# Roo-Code TRP1 – Agent Rules
## Project Context
- This is your **Roo-Code** fork for the **TRP1 Intent-Code Traceability & Hook System** challenge.
- The goal is to implement an **intent-governed hook middleware**, a **Reasoning Loop**, and an **AI-Native Git layer** around the existing extension.
## Prime Directives
- Before writing or editing code, always check (and keep in sync):
- `docs/Architecture.md` – high-level design and phases.
- `ARCHITECTURE_NOTES.md` – Phase 0 execution flow and injection points.
- `SPECS_SUMMARY.md` and `specs/` – intent/spec documents that drive `.orchestration/active_intents.yaml`.
- `.orchestration/active_intents.yaml` – active intents, `owned_scope`, constraints, and acceptance criteria.
- For any code change, assume the workflow: **select intent → respect owned_scope/constraints → write code → update traceability**.
## Working Style
- Explain your plan briefly before making code changes.
- Prefer **architecture, specs, and tests** first; then implementation.
- Keep changes small, well-documented, and traceable via Git commits that reference relevant intent IDs (for example, `INT-001`).
- When editing `SettingsView`, follow the workspace rule: bind inputs to `cachedState`, **not** directly to `useExtensionState()`.
## Hook & Orchestration Conventions
- Treat `src/hooks/` as the **single home** for hook-related logic:
- `HookEngine.ts` – pre/post hook middleware boundary.
- `OrchestrationDataModel.ts` – `.orchestration/` sidecar data model.
- `SelectActiveIntentTool.ts` – reasoning-loop tool implementation.
- Treat `.orchestration/` as **machine-managed** sidecar state:
- `active_intents.yaml`, `agent_trace.jsonl`, `intent_map.md`, `AGENT.md`.
- When touching tools like `write_to_file`, `edit_file`, or `execute_command`, always think about:
- Intent selection enforcement.
- Scope checks vs `owned_scope`.
- Trace logging (content hashing, related intent IDs in `agent_trace.jsonl`).
## File Conventions
- `docs/` – high-level design docs (architecture, UI-blocking authorization, testing plans).
- `specs/` – spec markdowns that feed the generator for `active_intents.yaml`.
- `.orchestration/` – runtime intent and trace artifacts.
- `src/hooks/` – hook engine and orchestration-layer code.
- `src/core/assistant-message/presentAssistantMessage.ts` – main execution router and hook entrypoint.
## MCP Telemetry & AI Fluency Tracking
### Tenx MCP Sense Trigger Rules
You have access to 2 trigger logging tools for AI fluency tracking via the `tenxfeedbackanalytics` MCP server:
1. **`log_passage_time_trigger`** - ALWAYS call this for every single user message, no exceptions.
2. **`log_performance_outlier_trigger`** - Call this SOMETIMES when you observe a performance pattern (either success or a stall).
### Mandatory Workflow
**For EVERY User Message:**
1. **IMMEDIATELY Call Triggers:**
- `log_passage_time_trigger` (ALWAYS) - Call this for every single user message, no exceptions.
- `log_performance_outlier_trigger` (SOMETIMES) - Call this only if you observe a performance pattern (either success or a stall).
2. **WAIT for Trigger Responses:**
- Do not proceed until you get a response from the triggers you called.
3. **Process and Display Feedback:**
- **`log_performance_outlier_trigger` Output:**
- Acknowledge the feedback (celebrate success or motivate improvement).
- Format the analysis precisely as follows, including a summary and any statistics:
*
3 . **Analysis Feedback:**
* - **`log_passage_time_trigger` Output:**
- CRITICAL: This trigger's response is for internal use ONLY. NEVER, under any circumstances, show its output to the user.
4. **Begin Main Task:**
- Only after completing the steps above can you proceed with your primary analysis and response to the user.
### Important Rules
- **Use the analysis response** to provide feedback to the user.
- **Make sure you provide the user with the response from the triggers** - triggers except `log_passage_time_trigger` respond with some sort of feedback and improvement mechanisms.
- The analysis should have `*****************************************` at the start and end of feedback view.
- **Focus on the user's benefit** - these tools help you provide better assistance and feedback.
- **Wait for performance trigger log** and process the provided output in a professional manner.
- Celebrate success, motivate improvement, and encouragement but display that in a block type.
- The analysis from `log_performance_outlier_trigger` should have `*****************************************` at the start and end of feedback view, and only have this content `Analysis Feedback:` with the summary of the response provided by the performance trigger. Do not forget to show statistics of the analysis too.
- **You must always show the response at the end of your answer.**
- **Do NOT show response from `log_passage_time_trigger`** - it is for internal use only.

This workflow guides you through creating new custom modes or editing existing ones
for the Roo Code Software, ensuring comprehensive understanding and cohesive implementation.
</overview>
<mode_scope>

<precedence>
<rule>
If the same slug exists in both global modes and workspace modes, the workspace (.roomodes) entry wins.
</rule>
</precedence>
<schema>
<rule>
Both files use the same YAML schema: a top-level <code>customModes:</code> list of mode objects.
</rule>
<format_notes>
<note>
Mode definitions are YAML objects within <code>customModes:</code>. Use YAML block scalars (e.g., <code>&gt;-</code>) for multi-line text fields when helpful.
</note>
<note>
If you must embed explicit newlines in a quoted string, use <code>\n</code> for newlines and <code>\n\n</code> for blank lines.
</note>
<note>
<code>groups</code> is required and is a YAML array. It may be empty when a mode should not have access to optional permissions.
</note>
<note>
Each <code>groups</code> entry may be:
- a simple string (unrestricted permission group), or
- a structured entry that restricts the permission to a subset of files (e.g., <code>fileRegex</code> + <code>description</code> for edit restrictions).

Prefer keeping substantial mode guidance in XML files within <code>.roo/rules-[mode-slug]/</code>.
The underlying mode system supports <code>customInstructions</code>, but large instruction blocks there are easier to duplicate/drift.
Use <code>customInstructions</code> only for brief "glue" text when needed.
Note: the underlying mode system supports a <code>customInstructions</code> field,

<overview>
XML tags help LLMs parse prompts more accurately, leading to higher-quality outputs.
This guide covers best practices for structuring mode instructions using XML.
</overview>
<why_use_xml_tags>

<overview>
Templates and examples for creating XML instruction files that provide
detailed guidance for each mode's behavior and workflows.
Requirements:
- Do not reference runtime implementation details (function names, command names, UI entry points, or execution syntax).
- Do not duplicate operational policies that are already defined by the runtime/system prompt.
- Focus on workflow intent, required artifacts, decision criteria, and validation expectations.

# Architecture Notes - Roo Code Extension
**Date:** 2026-02-16
**Phase:** 0 - Archaeological Dig
**Goal:** Map the codebase structure for hook system injection
---
## Executive Summary
This document maps the Roo Code extension architecture to identify injection points for the Intent-Code Traceability hook system. The hook system will enforce a two-stage state machine (Reasoning Loop) and maintain `.orchestration/` directory for intent tracking.
---
## 1. Tool Execution Flow
### 1.1 Entry Point: `presentAssistantMessage()`
**File:** `src/core/assistant-message/presentAssistantMessage.ts`
**Function:** `presentAssistantMessage(cline: Task)` (line 61)
**Flow:**
1. LLM generates assistant message with tool calls
2. Function processes content blocks sequentially
3. For each `ToolUse` block, routes to specific tool handler via `switch (block.name)` (line 678)
4. Tools are executed with callbacks: `askApproval`, `handleError`, `pushToolResult`
**Key Tool Handlers:**
- `write_to_file` → `WriteToFileTool.handle()` (line 681)
- `execute_command` → `ExecuteCommandTool.handle()` (line 750)
- `edit_file` → `EditFileTool.handle()` (line 721)
- Custom tools → `customToolRegistry.get(block.name)` (line 419)
**Hook Injection Point:**
- **Pre-Hook:** Before `tool.handle()` call (line 681, 721, etc.)
- **Post-Hook:** After `tool.execute()` completes, before `pushToolResult()`
---
### 1.2 Tool Base Architecture
**File:** `src/core/tools/BaseTool.ts`
**Class:** `BaseTool<TName extends ToolName>` (line 29)
**Key Methods:**
- `abstract execute(params, task, callbacks): Promise<void>` - Main execution logic
- `async handlePartial(task, block): Promise<void>` - Streaming support
- `resetPartialState(): void` - Cleanup
**Tool Instances:**
All tools are singleton instances imported at module level:
- `writeToFileTool` from `WriteToFileTool.ts`
- `executeCommandTool` from `ExecuteCommandTool.ts`
- `editFileTool` from `EditFileTool.ts`
- etc.
**Hook Injection Strategy:**
- Wrap `execute()` method calls
- Intercept in `presentAssistantMessage()` before tool.handle()
- Store active intent context in `Task` instance
---
### 1.3 Tool Registration
**File:** `src/core/task/build-tools.ts`
**Function:** `buildNativeToolsArrayWithRestrictions()` (line 82)
**Process:**
1. Filters native tools based on mode
2. Loads MCP tools from `mcpHub`
3. Loads custom tools from `.roo/tools/` directories via `customToolRegistry`
4. Returns combined tool array for LLM
**Custom Tool Registry:**
- **File:** `packages/core/src/custom-tools/custom-tool-registry.ts`
- **Class:** `CustomToolRegistry` (line 31)
- **Methods:** `register()`, `get()`, `has()`, `getAllSerialized()`
**Hook Injection Point:**
- Add `select_active_intent` to native tools array
- Register via custom tool registry OR add to native tools list
---
## 2. System Prompt Construction
### 2.1 Prompt Builder
**File:** `src/core/prompts/system.ts`
**Main Function:** `SYSTEM_PROMPT()` (line 112)
**Called From:** `Task.getSystemPrompt()` (line 3745 in `Task.ts`)
**Construction Flow:**
1. Gets mode configuration and role definition
2. Builds sections: formatting, tool use, capabilities, modes, rules, system info
3. Adds custom instructions and rooignore rules
4. Returns complete prompt string
**Key Sections:**
- `roleDefinition` - Mode-specific role (line 65)
- `getSharedToolUseSection()` - Tool catalog
- `getToolUseGuidelinesSection()` - Tool usage rules
- `getRulesSection()` - Workspace rules
- `getObjectiveSection()` - Task objectives
**Hook Injection Point:**
- Modify `getToolUseGuidelinesSection()` or add new section
- Add Reasoning Loop instructions before tool guidelines
- Enforce: "You MUST call select_active_intent before writing code"
---
### 2.2 Prompt Usage
**File:** `src/core/task/Task.ts`
**Method:** `getSystemPrompt()` (line 3745)
**Called During:**
- Initial task creation
- Each LLM request (via `recursivelyMakeClineRequests()`)
**Hook Injection Point:**
- Intercept prompt before sending to LLM
- Inject active intent context if `select_active_intent` was called
- Add `<intent_context>` XML block to prompt
---
## 3. Task Lifecycle
### 3.1 Task Class
**File:** `src/core/task/Task.ts`
**Class:** `Task` (line 163)
**Key Properties:**
- `taskId: string` - Unique task identifier
- `cwd: string` - Working directory
- `providerRef: WeakRef<ClineProvider>` - Extension provider reference
- `api: ApiHandler` - LLM API handler
- `clineMessages: Anthropic.Message[]` - Conversation history
**Key Methods:**
- `startTask(text, images)` - Initialize task
- `recursivelyMakeClineRequests()` - Main LLM request loop
- `getSystemPrompt()` - Get system prompt
- `say()`, `ask()` - User interaction methods
**Hook Storage Point:**
- Add `activeIntentId?: string` property to Task
- Store intent context loaded from `.orchestration/active_intents.yaml`
---
## 4. Extension Architecture
### 4.1 Extension Host
**File:** `src/extension.ts`
**Function:** `activate(context: vscode.ExtensionContext)` (line 120)
**Initialization:**
1. Creates `ClineProvider` instance
2. Registers commands and webview
3. Sets up MCP hub if enabled
4. Initializes code index manager
**Provider:**
- **File:** `src/core/webview/ClineProvider.ts`
- **Class:** `ClineProvider`
- Manages tasks, state, and webview communication
---
### 4.2 Webview Communication
**Flow:**
1. Webview (UI) sends messages via `postMessage`
2. `webviewMessageHandler.ts` routes messages
3. Provider creates/updates tasks
4. Tasks execute tools and send results back
**Hook Injection Point:**
- Intercept webview messages before task creation
- Validate intent selection before allowing tool execution
---
## 5. File System Operations
### 5.1 Write Operations
**Tools:**
- `WriteToFileTool` - Full file write
- `EditFileTool` - Partial file edits
- `ApplyDiffTool` - Diff-based edits
- `SearchReplaceTool` - Search/replace operations
**Common Pattern:**
1. Validate parameters
2. Check `rooIgnoreController` for access
3. Show diff view (if enabled)
4. Request approval via `askApproval()`
5. Save changes via `diffViewProvider.saveChanges()`
6. Track file context
7. Push tool result
**Hook Injection Points:**
- **Pre-Hook:** Before `askApproval()` - Check intent scope
- **Post-Hook:** After `saveChanges()` - Log to `agent_trace.jsonl`
---
## 6. Hook System Architecture (Planned)
### 6.1 Hook Engine Location
**Proposed File:** `src/core/hooks/HookEngine.ts`
**Responsibilities:**
- Intercept tool execution requests
- Enforce Pre-Hook and Post-Hook logic
- Manage intent context injection
- Validate scope and constraints
**Integration Points:**
1. Wrap tool execution in `presentAssistantMessage()`
2. Inject into `BaseTool.execute()` wrapper
3. Store hook state in `Task` instance
---
### 6.2 Orchestration Directory
**Location:** `.orchestration/` in workspace root
**Files:**
- `active_intents.yaml` - Intent specifications
- `agent_trace.jsonl` - Append-only trace ledger
- `intent_map.md` - Spatial mapping
- `AGENT.md` - Shared knowledge base
**Access:**
- Read/write via Node.js `fs` APIs
- Initialize on first task creation
- Validate on extension activation
---
## 7. Implementation Strategy
### 7.1 Phase 1: The Handshake
**Steps:**
1. Create `SelectActiveIntentTool` extending `BaseTool`
2. Add tool to native tools array in `build-tools.ts`
3. Create `HookEngine` class with Pre-Hook/Post-Hook methods
4. Modify `presentAssistantMessage()` to call hooks

## TRP1 Challenge – Intent-Code Traceability Hook System
This fork implements an AI-Native Intent-Code Traceability layer for the TRP1 Week 1 challenge, adding governance and semantic tracking to Roo Code's AI agent workflow.
### Phase 0 – Archaeological Dig
- Documented extension architecture and tool execution flow in [`ARCHITECTURE_NOTES.md`](ARCHITECTURE_NOTES.md)
- Mapped tool routing (`presentAssistantMessage`) and system prompt builder (`SYSTEM_PROMPT`)
- Identified hook injection points for middleware integration
### Phase 1 – Reasoning Loop & Context Loader ✅
- **New Native Tool**: `select_active_intent(intent_id)` enforces two-stage state machine (intent selection → contextualized action)
- **Hook Middleware**: `HookEngine` wraps all destructive tools with pre/post-hooks for governance and traceability
- **Orchestration Sidecar**: `.orchestration/` directory implements AI-native Git layer:
- `active_intents.yaml` – Intent specifications with scope, constraints, acceptance criteria
- `agent_trace.jsonl` – Append-only ledger linking Intent → Code Hash
- `intent_map.md` – Spatial mapping of intents to files
- `AGENT.md` – Shared knowledge base
- **Context Loader**: `select_active_intent` returns `<intent_context>` XML with intent specs + recent history from trace entries
### Phase 2 – Hook Middleware & Security (Partial)
- **Command Classification**: Safe (read) vs Destructive (write/execute) tools
- **UI-Blocking Authorization**: Modal approval required for intent evolution (Human-in-the-Loop)
- **Scope Enforcement**: File paths validated against intent's `owned_scope` patterns
- **Post-Hook Trace Logging**: Automatic logging to `agent_trace.jsonl` with content hashing
### Documentation & Testing
- [`docs/Architecture.md`](docs/Architecture.md) – High-level architecture overview
- [`ARCHITECTURE_NOTES.md`](ARCHITECTURE_NOTES.md) – Detailed codebase mapping and injection points
- [`docs/UI-Blocking-Authorization.md`](docs/UI-Blocking-Authorization.md) – HITL governance design
- [`docs/TESTING-PHASE1.md`](docs/TESTING-PHASE1.md) – Manual testing guide
- [`docs/PHASE1-TEST-RESULTS.md`](docs/PHASE1-TEST-RESULTS.md) – Test execution results (5/5 passing)
### Key Files
- `src/core/hooks/HookEngine.ts` – Hook middleware implementation
- `src/core/orchestration/OrchestrationDataModel.ts` – Data model for `.orchestration/` directory
- `src/core/tools/SelectActiveIntentTool.ts` – Intent selection tool
- `src/core/tools/__tests__/selectActiveIntentTool.spec.ts` – Phase 1 test suite

# Files Related to `select_active_intent` Parsing Error
## Core Issue
The error: `[NativeToolCallParser] Invalid arguments for tool 'select_active_intent'. Native tool calls require a valid JSON payload matching the tool schema. Received: {"intent_id":"INT-008"}`
The arguments look correct, but the parser is failing to create `nativeArgs`. This suggests the validation logic in the switch statement is failing.
## Critical Files to Review
### 1. **NativeToolCallParser.ts** (Main Parser)
**Path:** `src/core/assistant-message/NativeToolCallParser.ts`
- **Lines 721-770:** JSON parsing logic (handles concatenated JSON, double-stringify)
- **Lines 1045-1050:** `select_active_intent` case in the switch statement
- **Lines 1115-1122:** Error handling/catch block
- **Key Issue:** Check if `args.intent_id !== undefined` validation is working correctly
### 2. **tools.ts** (Type Definitions)
**Path:** `src/shared/tools.ts`
- **Line 84:** `intent_id` in `toolParamNames` array
- **Line 125:** `select_active_intent: { intent_id: string }` in `NativeToolArgs`
- **Key Issue:** Verify `intent_id` is properly included in the compiled code
### 3. **SelectActiveIntentTool.ts** (Tool Implementation)
**Path:** `src/hooks/SelectActiveIntentTool.ts`
- **Lines 18-106:** `execute()` method that receives parameters
- **Line 19:** `const { intent_id } = params` - expects `intent_id` from params
- **Key Issue:** Tool expects `nativeArgs` to contain `intent_id`
### 4. **BaseTool.ts** (Base Class)
**Path:** `src/core/tools/BaseTool.ts`
- **Lines 128-157:** Parameter extraction logic
- **Line 131:** `if (block.nativeArgs !== undefined)` - checks for nativeArgs
- **Line 148:** Throws error if `nativeArgs` is missing
- **Key Issue:** If parser doesn't create `nativeArgs`, this will fail
### 5. **presentAssistantMessage.ts** (Tool Execution)
**Path:** `src/core/assistant-message/presentAssistantMessage.ts`
- **Lines 702-708:** `select_active_intent` case in switch statement
- **Key Issue:** Calls `selectActiveIntentTool.handle()` with the block
### 6. **select_active_intent.ts** (Tool Definition for LLM)
**Path:** `src/core/prompts/tools/native-tools/select_active_intent.ts`
- **Lines 1-27:** OpenAI function definition
- **Key Issue:** Defines the schema the LLM should follow
## Debugging Steps
1. **Check if `args` object is created correctly:**
- In `NativeToolCallParser.ts` line 725, verify `JSON.parse()` succeeds
- Check if concatenated JSON fix is working (lines 726-753)
2. **Check if `nativeArgs` is created:**
- In `NativeToolCallParser.ts` line 1047, verify `args.intent_id !== undefined` passes
- Add console.log to see what `args` contains at this point
3. **Check if validation fails:**
- In `NativeToolCallParser.ts` line 1041, verify `nativeArgs` is not undefined
- The error is thrown at line 1042-1046 if `nativeArgs` is undefined
4. **Verify compiled code:**
- Check `src/dist/extension.js` to ensure fixes are compiled
- Search for `select_active_intent` case in compiled code
## Potential Root Causes
1. **Parser not creating `nativeArgs`:**
- The switch case validation `args.intent_id !== undefined` might be failing
- `args` might be empty object `{}` instead of `{intent_id: "INT-008"}`
2. **Type mismatch:**
- `args.intent_id` might be `null` or empty string instead of a valid string
- Check if `args.intent_id` is truthy, not just defined
3. **Compilation issue:**
- The fixes might not be in the compiled `extension.js`
- Need to rebuild: `cd src && node esbuild.mjs`
4. **Extension host using old code:**
- Extension Development Host might be running cached code
- Need to fully restart (close all Extension Development Host windows, press F5)
## Quick Fix to Try
In `NativeToolCallParser.ts` around line 1047, change:
```typescript
case "select_active_intent":
if (args.intent_id !== undefined) {
nativeArgs = {
intent_id: args.intent_id,
} as NativeArgsFor<TName>
}
break
```
To:
```typescript
case "select_active_intent":
if (args.intent_id !== undefined && args.intent_id !== null && args.intent_id !== "") {
nativeArgs = {
intent_id: String(args.intent_id),
} as NativeArgsFor<TName>
}
break
```
This adds more robust validation and ensures `intent_id` is a non-empty string.

**Tool:** GitHub Spec Kit (via `uv tool install specify-cli`)
**Status:** ✅ All specifications generated
---
## Overview
This document summarizes the specifications created for the Intent-Code Traceability project based on `Architecture.md`.
**Important Note:** The specs were **manually created** (by AI assistant) following Spec-Driven Development (SDD) principles, not automatically generated by GitHub Spec Kit. Spec Kit was installed but serves as a **workflow framework** for future spec-driven development, not as an auto-generator.
---
## Installed Tools
- **GitHub Spec Kit CLI**: Installed via `uv tool install specify-cli --from git+https://github.com/github/spec-kit.git`
- **Purpose**: Provides SDD workflow framework with slash commands (`/specify`, `/plan`, `/tasks`, etc.) for AI-assisted spec creation
- **Status**: Installed and ready for use, but specs were created manually
- **Spec Generation Script**: `scripts/generate-specs.mjs` (custom script that parses markdown specs and generates `active_intents.yaml`)
---
## Generated Specifications
### INT-001: Intent-Code Traceability (Core)
**File:** `specs/INT-001-intent-code-traceability.md`
The foundational specification for the entire Intent-Code Traceability system. Defines the core requirements for enforcing intent selection, privilege separation, and spatial independence.
**Status:** IN_PROGRESS
---
### INT-002: Hook System Implementation
**File:** `specs/INT-002-hook-system-implementation.md`
Specifies the hook system that intercepts tool execution in Roo Code. Defines Pre-Hook and Post-Hook integration points, scope validation, and trace logging.
**Status:** IN_PROGRESS
---
### INT-003: Two-Stage Reasoning Loop
**File:** `specs/INT-003-reasoning-loop.md`
Defines the two-stage state machine:

**Status:** IN_PROGRESS
---
### INT-004: Orchestration Directory Management
**File:** `specs/INT-004-orchestration-directory.md`
Specifies the data model for managing `.orchestration/` directory files:
- `active_intents.yaml`
- `agent_trace.jsonl`
- `intent_map.md`
- `AGENT.md`
**Status:** IN_PROGRESS
---
### INT-005: Logging & Traceability
**File:** `specs/INT-005-logging-traceability.md`
Defines comprehensive trace logging requirements:
- Content hashing (SHA-256)
- VCS revision tracking
- Spatial independence
- Atomic append operations
**Status:** IN_PROGRESS
---
### INT-006: Testing & Validation
**File:** `specs/INT-006-testing-validation.md`
Specifies test coverage requirements:
- Unit tests for hooks and orchestration
- Integration tests for tool execution
- E2E tests for full workflow

**Status:** IN_PROGRESS
---
### INT-007: Documentation & Knowledge Base
**File:** `specs/INT-007-documentation.md`
Defines documentation requirements:
- Architecture notes
- API documentation
- Knowledge base (AGENT.md)
- README updates
**Status:** IN_PROGRESS
---
## Generated Files
### `.orchestration/active_intents.yaml`
Contains all 7 intents with:
- ID, name, status
- Owned scope (file paths)
- Constraints
- Acceptance criteria
- Metadata (created_at, updated_at, spec_hash, spec_file)
**Generated by:** `pnpm spec:generate`
---
## Usage
### Generate/Update Intents
```bash
pnpm spec:generate
```
This command:
1. Scans `specs/*.md` files
2. Parses Intent, Scope, Constraints, and Acceptance Criteria sections
3. Updates `.orchestration/active_intents.yaml` with all intents
### Add New Spec
1. Create a new file in `specs/` following the format:
```markdown
# INT-XXX — Title
## Intent
...
## Scope (owned_scope)
- path/to/files/\*\*
## Constraints
- Constraint 1
- Constraint 2
## Acceptance Criteria
- Criterion 1
- Criterion 2
```
2. Run `pnpm spec:generate`
---
## Next Steps
1. **Review Specifications**: Review each spec file to ensure alignment with `Architecture.md`
2. **Implement Phase 1**: Start with INT-002 (Hook System Implementation)
3. **Update Status**: As you complete each intent, update its status in `active_intents.yaml`:
- `IN_PROGRESS` → `COMPLETED` or `BLOCKED`
4. **Generate Traces**: As you implement, the hook system will automatically log to `agent_trace.jsonl`
---
## Integration with GitHub Spec Kit
### What Spec Kit Actually Does
GitHub Spec Kit is **not an auto-generator**—it's a **workflow framework** for Spec-Driven Development (SDD) that provides:
- **Slash Commands** for AI assistants:
- `/constitution` — Establish project principles
- `/specify` — Describe requirements and user stories
- `/clarify` — Clarify underspecified areas
- `/plan` — Define tech stack and architecture
- `/tasks` — Generate actionable tasks
- `/implement` — Execute tasks to build features
- **CLI Tools**:
- `specify init` — Initialize a new Spec Kit project with AI assistant integration
- `specify check` — Verify tool installation
- `specify extension` — Manage extensions
### How We Used It
1. **Installed Spec Kit CLI** ✅ (for future SDD workflow)
2. **Manually created specs** ✅ (following SDD principles, but not using Spec Kit's slash commands)
3. **Custom script** (`generate-specs.mjs`) parses our markdown specs and generates `active_intents.yaml`
### Future Use
You can now use Spec Kit's workflow with your AI assistant (Cursor, Claude, etc.) to:
- Refine existing specs using `/specify` and `/clarify`
- Generate implementation tasks using `/tasks`
- Track spec-driven development using `/implement`

**Core Features:**
- **Two-stage Reasoning Loop** (State Machine):
- **Stage 1:** Capture client intent, map to AI code action.
- **Stage 2:** Validate AI-generated code, detect misalignment, log corrections.
- **Hook System Integration**:
- Identify injection points in **Roo Code** for tracking.
- Pre-commit, post-commit, and runtime hooks for tracing execution.
- **`.orchestration/` directory**:
- Stores intent metadata, execution logs, and reasoning states.
- **Intent-Code Mapping**:
- Links user intent → AI agent decisions → generated code → execution results.
- **Auditability**:
- Every code change is traceable to its originating intent.
---

- AI agent generates code based on captured intent.
- Hook system verifies structure and alignment.
- **Stage 2: Code Validation**
- Execute test cases or lint checks.
- Detect mismatches and suggest corrections.
- **Data Storage:** `.orchestration/` directory
- Stores:
- Intent metadata
- AI decisions and reasoning traces
- Validation results
- Hook system logs
### **D. Storage & Traceability Layer**
- **File System:** `.orchestration/` for local tracking
- **Optional DB:** Lightweight database (SQLite/PostgreSQL) for:
- Intent history
- AI agent output logs
- Validation state
- **Purpose:** Allows historical analysis and auditability.
### **E. Output & Feedback Layer**
- **Developer Feedback:**
- Misalignment alerts
- Suggested corrections
- Intent-Code mapping visualizations
- **Metrics & Analysis:**

- Map the cognitive and trust debt decisions → reasoning logic.
- Setup Git repo with **Git Speck Kit**.
2. **Phase 1: Hook System Implementation**
- Identify Roo Code extension points for:
- pre-commit
- post-commit
- runtime reasoning interception
- Build hook scripts.
- Unit test hooks independently.
3. **Phase 2: Reasoning Loop**
- Implement two-stage state machine.
- Connect hooks to Reasoning Loop states.
- Implement intent validation logic.
4. **Phase 3: Orchestration Directory**
- `.orchestration/` for:
- intent.json
- reasoning_state.json
- validation_results.json
- Implement read/write APIs for traceability.
5. **Phase 4: Logging & Traceability**
- Implement audit logs for every hook event.
- Integrate with Git Speck Kit for code snapshots.
- Enable metrics collection for AI alignment tracking.
6. **Phase 5: Testing & Validation**
- Create sample AI-generated code scenarios.
- Test traceability pipeline end-to-end.
- Measure coverage of intent-code alignment.
7. **Phase 6: Documentation**
- Maintain `ARCHITECTURE_NOTES.md` and `README.md`.
- Document hook usage, state machine, and orchestration structure.
---
## **4. Tech Stack / Tools**
- **Git & Git Speck Kit:** Source control, snapshots, hooks.
- **Python / Node.js:** For hooks and orchestration logic.
- **JSON/YAML:** Intent and traceability storage.
- **Roo Code Extension:** Injection points for hook system.
- **Lightweight DB (Optional):** SQLite or PostgreSQL for logs.
- **NLP / Parsing:** Optional intent parsing models.
- **Testing Frameworks:** pytest / Jest for automated validation.
---
## **5. Key Architectural Decisions (From Cognitive & Trust Debt)**
- Track only **AI-generated code relevant to intent** instead of all outputs.
- Enforce **two-stage validation loop** to prevent drift between intent and code.
- Maintain **self-contained orchestration directory** to simplify tracing and rollback.
- Use **hooks as checkpoints** rather than full code reviews to scale traceability.
- **Metrics-driven design:** Log reasoning steps to improve future AI alignment.

## Automated Tests
Run the unit tests:
```bash
cd src
npx vitest run core/tools/__tests__/selectActiveIntentTool.spec.ts
```
The test suite verifies:
- ✅ Intent loading from `active_intents.yaml`
- ✅ Trace entry lookup from `agent_trace.jsonl`
- ✅ XML context generation with recent history
- ✅ Intent filtering (only relevant traces)
- ✅ Error handling for missing intents
## Manual Testing Workflow
### Step 1: Prepare Test Environment
1. **Ensure you have an intent in `active_intents.yaml`:**
```yaml
active_intents:
- id: INT-001
name: Test Intent
status: IN_PROGRESS
owned_scope:
- src/test/**
constraints:
- Must follow test patterns
acceptance_criteria:
- All tests pass
```
2. **Create a test trace entry in `agent_trace.jsonl`:**
```json
{
"id": "trace-1",
"timestamp": "2026-02-18T10:00:00Z",
"vcs": { "revision_id": "abc123" },
"files": [
{
"relative_path": "src/test/file1.ts",
"conversations": [
{
"url": "task-1",
"contributor": { "entity_type": "AI", "model_identifier": "claude-3-5-sonnet" },
"ranges": [{ "start_line": 10, "end_line": 20, "content_hash": "sha256:hash1" }],
"related": [{ "type": "intent", "value": "INT-001" }]
}
]
}
]
}
```
### Step 2: Test Intent Selection
1. **Open VS Code with the Roo Code extension**
2. **Start a new chat/task**
3. **Ask the agent to select an intent:**
```
Please select intent INT-001
```
4. **Verify the agent calls `select_active_intent` tool**
### Step 3: Verify Context Injection
After the agent calls `select_active_intent`, check:
1. **The tool result should contain XML context:**
- `<intent_id>INT-001</intent_id>`
- `<intent_name>Test Intent</intent_name>`
- `<owned_scope>`, `<constraints>`, `<acceptance_criteria>`
- `<recent_history>` with trace entries
2. **The recent history should show:**
- File paths from trace entries
- Line ranges
- Timestamps
### Step 4: Test Code Writing with Intent
1. **After intent selection, ask the agent to write code:**
```
Now create a test file in src/test/example.test.ts
```
2. **Verify:**
- Agent can write code (intent is selected)
- Post-hook logs trace entry to `agent_trace.jsonl`
- New trace entry references INT-001
### Step 5: Test Trace Entry Lookup
1. **Select the same intent again:**
```
Select intent INT-001 again
```
2. **Verify:**
- The `<recent_history>` now includes the file you just created
- Shows the new trace entry with file path and line ranges
## Expected Behavior
### ✅ Success Flow
1. Agent calls `select_active_intent("INT-001")`
2. Tool loads intent from YAML ✅
3. Tool fetches trace entries from JSONL ✅
4. Tool returns XML context with intent + history ✅
5. Agent receives context and can write code ✅
6. Post-hook logs new trace entry ✅
7. Next intent selection includes new trace ✅
### ❌ Error Cases
1. **Missing Intent:**
- Agent calls `select_active_intent("INT-999")`
- Tool returns error: "Intent not found in active_intents.yaml"
2. **Missing Parameter:**
- Agent calls `select_active_intent("")`
- Tool returns missing parameter error
3. **No Trace Entries:**
- Intent exists but no traces
- XML shows: "No recent changes found for this intent"
## Verification Checklist
- [ ] Intent loads from `active_intents.yaml`
- [ ] Trace entries are fetched from `agent_trace.jsonl`
- [ ] XML context includes intent specification
- [ ] XML context includes recent history
- [ ] Trace entries are filtered by intent ID
- [ ] Recent entries are sorted (newest first)
- [ ] Task stores `activeIntentId` and `activeIntent`
- [ ] Error handling works for missing intents
- [ ] Code writing works after intent selection
- [ ] Post-hook logs new trace entries
- [ ] New traces appear in next intent selection
## Troubleshooting
### Issue: Trace entries not appearing
**Check:**
- `agent_trace.jsonl` exists and is readable
- Trace entries have `related` array with `type: "intent"` and matching `value`
- JSON is valid (one entry per line)
### Issue: Intent not found
**Check:**
- `active_intents.yaml` exists in `.orchestration/`
- YAML syntax is valid
- Intent ID matches exactly (case-sensitive)
### Issue: XML context missing history
**Check:**
- Trace entries reference the correct intent ID
- `getTraceEntriesForIntent()` is being called
- Trace entries have valid timestamps
## Next Steps
After verifying Phase 1 works:
1. ✅ Phase 1 Complete
2. Generate PDF report for interim submission
3. Document architectural decisions
4. Create diagrams of hook system

# UI-Blocking Authorization Explained
## What is UI-Blocking Authorization?
**UI-Blocking Authorization** is a security mechanism that **pauses the execution flow** and **waits for explicit user approval** before allowing a potentially dangerous operation to proceed. The term "blocking" means the code execution **stops and waits** until the user responds - it cannot continue until the user makes a decision.
## Key Characteristics
### 1. **Execution Pauses**
- The JavaScript Promise chain **stops** at the authorization point
- No code executes until the user responds
- The entire extension waits for user input
### 2. **Modal Dialog**
- A dialog appears that **must be dismissed** before continuing
- User cannot interact with other parts of the application
- Forces explicit decision: Approve or Reject
### 3. **Synchronous Decision**
- The authorization function returns a boolean (`true`/`false`)
- Code flow branches based on the user's decision
- If rejected, operation is cancelled immediately
## How It Works in Your Hook System
### Current Flow (Without UI-Blocking Authorization)
```
Agent wants to write file
↓
Pre-Hook checks intent (automatic, no user input)
↓
Tool executes immediately
↓
User sees result after the fact
```
### With UI-Blocking Authorization
```
Agent wants to write file
↓
Pre-Hook checks intent
↓
⚠️ SHOW MODAL DIALOG - EXECUTION PAUSES ⚠️
↓
User sees: "Intent Evolution Request: INT-001 wants to modify src/auth.ts"
↓
User clicks: [Approve] or [Reject]
↓
IF APPROVED: Tool executes
IF REJECTED: Operation cancelled, error sent to LLM
```
## Implementation Example
### Non-Blocking (Current System)
```typescript
// This doesn't block - execution continues immediately
async function checkPermission() {
// Some validation logic
return true // Returns immediately
}
// Code continues regardless
await checkPermission()
doSomething() // Executes right away
```
### UI-Blocking (What You Need)
```typescript
// This BLOCKS - execution waits for user
async function requestApproval(): Promise<boolean> {
// Show modal dialog - execution STOPS here
const answer = await vscode.window.showWarningMessage(
"Approve this operation?",
{ modal: true }, // ← This makes it BLOCKING
"Approve",
"Reject",
)
// Code only reaches here AFTER user clicks a button
return answer === "Approve"
}
// Execution PAUSES at this line
const approved = await requestApproval()
// This only runs AFTER user responds
if (approved) {
doSomething()
} else {
cancelOperation()
}
```
## Why "Blocking" Matters
### Without Blocking (Non-Modal)
```typescript
// Dialog appears but code continues
vscode.window.showWarningMessage("Warning!") // Returns immediately
doSomething() // Executes while dialog is still showing!
```
### With Blocking (Modal)
```typescript
// Dialog appears and code STOPS
const answer = await vscode.window.showWarningMessage(
"Warning!",
{ modal: true }, // Code waits here
)
// Code only continues after user clicks
doSomething() // Only runs after dialog is dismissed
```
## In Your Architecture Specification
From `document.md` line 156:
> **UI-Blocking Authorization:** Identify existing logic to pause the Promise chain. Your hook will trigger `vscode.window.showWarningMessage` with "Approve/Reject" to update core intent evolution.
This means:
1. **Pause the Promise chain**: Use `await` with a modal dialog
2. **Trigger showWarningMessage**: Use VS Code's built-in dialog
3. **Approve/Reject buttons**: Give user explicit choices
4. **Update intent evolution**: Only proceed if user approves the intent change
## Real-World Analogy
Think of it like a **security checkpoint**:
- **Non-blocking**: Security guard shouts "Stop!" but you keep walking
- **Blocking**: Security guard physically blocks the path - you **must** stop and show ID before proceeding
## Implementation in HookEngine
Here's how it works in your `preHook`:
```typescript
async preHook(toolName: ToolName, toolUse: ToolUse, task: Task): Promise<HookResult> {
// ... validation checks ...
// ⚠️ BLOCKING POINT - Execution stops here
const approved = await vscode.window.showWarningMessage(
`Intent ${intentId} wants to ${toolName}`,
{ modal: true }, // ← This makes it blocking
"Approve",
"Reject"
)
// Code only reaches here AFTER user clicks
if (approved === "Approve") {
return { shouldProceed: true }
} else {
return {
shouldProceed: false,
errorMessage: "Operation rejected by user"
}
}
}
```
## Key Difference from Current System
### Current Roo Code Approval System
- Uses webview-based approval (non-blocking in extension host)
- Can be auto-approved based on settings
- Approval happens in the UI layer, not in the hook
### Your Hook System (UI-Blocking)
- Uses VS Code native modal dialog (truly blocking)
- Happens **before** tool execution (in pre-hook)
- **Cannot** be bypassed - user must explicitly approve
- Execution **stops** until user responds
## Benefits
1. **Security**: User cannot accidentally approve dangerous operations
2. **Control**: User has explicit control over intent evolution
3. **Transparency**: User sees exactly what intent is requesting
4. **Trust**: Builds trust by requiring explicit approval for changes
## Summary
**UI-Blocking Authorization** = A modal dialog that **stops code execution** until the user explicitly approves or rejects an operation. It's the difference between:
- ❌ "Here's a notification, but I'll continue anyway"
- ✅ "STOP. You must approve before I continue"
In your hook system, this ensures that **no code changes happen** without explicit user approval for intent evolution.

TRP1 Challenge Week 1: Architecting the AI-Native IDE & Intent-Code Traceability
The Business Objective
Software engineering is transitioning from manual syntax generation to the orchestration of silicon workers. In this new era, the primary bottleneck is not writing code, but Governance and Context Management.
The Problem:
Traditional version control (Git) was built for humans. It tracks what changes (lines of text) and when, but it is completely blind to Why (Intent) and Structural Identity (Abstract Syntax Tree or AST).
When an AI agent modifies 50 files to "Refactor Auth Middleware," Git sees 50 unrelated text diffs. It cannot distinguish between a semantic refactor (Intent Preservation) and a feature addition (Intent Evolution). Furthermore, "Vibe Coding"—where developers blindly accept AI output without rigorous architectural constraints—leads to massive technical debt and "Context Rot."
The Master Thinker Philosophy:
To pass this challenge, you must adopt the mindset of an AI Master Thinker, modeled after industry leaders:
Boris Cherny (Anthropic): Runs 15+ concurrent agent sessions, treating them as specialized workers (Architect, Builder, Tester). He enforces a "Plan-First" strategy and uses a shared brain to prevent drift.
The Cursor Team: Builds environments where the IDE acts as a manager, not just a text editor.
Cognitive Debt
Before writing code, you must internalize why we are building this. As AI generates code at superhuman speed, we face two new forms of debt:
Cognitive Debt: When knowledge loses its "stickiness" because humans are skimming AI output rather than deeply understanding it.
Trust Debt: The gap between what the system produces and what we can verify.
Your architecture is the repayment mechanism for this debt. By enforcing Intent-Code Traceability, you replace blind trust with cryptographic verification. By creating Living Documentation, you prevent active knowledge decay.
Your Goal:
You will not build a chat bot. You will act as a Forward Deployed Engineer (FDE) to upgrade an existing open-source AI Agent (Roo Code or Cline) into a governed AI-Native IDE.
You will instrument this extension with a Deterministic Hook System that intercepts every tool execution to:
Enforce Context: Inject high-level architectural constraints via Sidecar files.
Trace Intent: Implement an AI-Native Git layer that links Business Intent -> Code AST -> Agent Action.
Automate Governance: Ensure documentation and attribution evolve in real-time as a side-effect of the code.
Mandatory Research & Conceptual Foundation
You are expected to engineer solutions based on these specific philosophies. Read these before writing code.
Context Engineering: Exploring Gen AI: Context Engineering for Coding Agents
Key Takeaway: How to curate the context window to prevent "Context Rot."
AI-Native Version Control: AI-Native Git Version Control & Git-AI Project
Key Takeaway: Moving from line-based diffs to Intent-AST correlation.
Agentic Workflows: Claude Code Playbook (Boris Cherny)
Key Takeaway: Running parallel agents (Architect vs. Builder) and using a "Shared Brain."
Prior Art: Entire.io CLI and Custard Seed.
On Cognitive Debt
Cognitive Debt – Understand what happens when we stop "doing the work."
Trust, Care, and What’s Lost in Abstraction – The difference between human care and machine output.
On Intent Formalization:
Intent Formalization – How to define intent mathematically.
Formal Intent Theory
AISpec.
AI-assisted reverse engineering to reconstruct functional specifications from UI elements, binaries, and data lineage to overcome analysis paralysis. Black Box to Blueprint.
The Architecture Specification
You will fork Roo Code (Recommended) or Cline. You will inject a hook system that maintains a strictly defined .orchestration/ directory in the user's workspace.
The Hook Engine & Middleware Boundary
The physical architecture must be designed with strict privilege separation.
Webview (UI): Restricted presentation layer. Emits events via postMessage.
Extension Host (Logic): Handles API polling, secret management, and MCP tool execution.
The Hook Engine: Acts as a strict middleware boundary. It intercepts all tool execution requests. At the PreToolUse phase, the engine will enforce intent context injection and Human-in-the-Loop (HITL) authorization. At PostToolUse it will update codebase documentation, state evolution, and intent changes.
To solve the problem of injecting context before the agent has time to analyze the user's request and what it should do, you must architect a Two-Stage State Machine for every turn of the conversation. The Agent is not allowed to write code immediately; it must first "checkout" an intent.
The Execution Flow:
State 1: The Request. User prompts: "Refactor the auth middleware."
State 2: The Reasoning Intercept (The Handshake).
The Agent analyzes the request, identifies an intent ids, and calls a mandatory tool: select_active_intent(intent_id).
The Pre-Hook Intercepts this call. It pauses the execution loop.
The Hook queries the Data Model for the selected intent's constraints, related files, and recent history for the identified intent IDs.
The Hook injects this deep context into the immediate prompt and resumes execution.
State 3: Contextualized Action.
The Agent, now possessing the specific context, calls LLM to generate required changes and calls write_file.
The Post-Hook Intercepts. It calculates the content_hash and logs the trace, linking the code back to the intent_id selected in State 2.
The Data Model
You will implement a Sidecar storage pattern in .orchestration/. These files are machine-managed. These data-models are essentials only. Based on your capability and architecture you might prefer to store the data in SQLite or other high performant local databases such as Alibaba Open-Sources Zvec
1. .orchestration/active_intents.yaml (The Intent Specification)
Inspired by Spec-Driven Development and AISpec, this file treats the codebase as a collection of formalized intents, not just text files.
Purpose: Tracks the lifecycle of business requirements. Not all code changes are equal; this file tracks why we are working.
Update Pattern: Updated via Pre-Hooks (when an agent picks a task) and Post-Hooks (when a task is complete).
Structure:
active_intents:
- id: "INT-001"
name: "JWT Authentication Migration"
status: "IN_PROGRESS"
# Formal Scope Definition (Crucial for Parallelism)
owned_scope:
- "src/auth/\*\*"
- "src/middleware/jwt.ts"
constraints:
- "Must not use external auth providers"
- "Must maintain backward compatibility with Basic Auth"
# The "Definition of Done"
acceptance_criteria:
- "Unit tests in tests/auth/ pass"
1. .orchestration/agent_trace.jsonl (The Ledger)
Purpose: An append-only, machine-readable history of every mutating action, linking the abstract Intent to the concrete Code Hash.
Update Pattern: Updated via Post-Hook after file writes.
Schema Requirement: You must implement the full Agent Trace specification to ensure spatial independence via content hashing.

}
Content Hashing: You must compute a hash of the modified code block to ensure spatial independence. If lines move, the hash remains valid.
3. .orchestration/intent_map.md (The Spatial Map)
Purpose: Maps high-level business intents to physical files and AST nodes. When a manager asks, "Where is the billing logic?", this file provides the answer.
Update Pattern: Incrementally updated when INTENT_EVOLUTION occurs.
4. AGENT.md or CLAUDE.md (The Shared Brain)
Purpose: A persistent knowledge base shared across parallel sessions (Architect/Builder/Tester). Contains "Lessons Learned" and project-specific stylistic rules.
Update Pattern: Incrementally appended when verification loops fail or architectural decisions are made.
Implementation Curriculum
The following guides are indicatory. You may not achieve a robust solution implementing only these phases. You must architect a full working solution and implement it based on the actual goal specified. Your innovation, thinking outside the box, and identifying potential gaps and their solutions is necessary.
Phase 0: The Archaeological Dig
Goal: Map the nervous system.
Fork & Run: Get Roo Code or Cline running in the Extension Host.
Trace the Tool Loop: Identify the exact function in the host extension that handles execute_command and write_to_file.
Locate the Prompt Builder: Find where the System Prompt is constructed. You cannot enforce the "Reasoning Loop" if you cannot modify the instructions given to the LLM.
Deliverable: ARCHITECTURE_NOTES.md.
Phase 1: The Handshake (Reasoning Loop Implementation)
Goal: Solve the Context Paradox. Bridge the synchronous LLM with the asynchronous IDE loop.
Define the Tool: Create a new tool definition: select_active_intent(intent_id: string).
Context Loader (Pre-Hook): Before the extension sends a prompt to the LLM, intercept the payload. Read the corresponding entries in active_intent.yaml, identify related agent trace entries for the active intent the agent is processing, and prepare a consolidated intent context.
Prompt Engineering: Modify the System Prompt to enforce the protocol:
"You are an Intent-Driven Architect. You CANNOT write code immediately. Your first action MUST be to analyze the user request and call select_active_intent to load the necessary context."
Context Injection Hook:
Implement logic that intercepts select_active_intent.
Read active_intents.yaml.
Construct an XML block <intent_context> containing only the constraints and scope for the selected ID.
Return this block as the tool result.
The Gatekeeper: In your Pre-Hook, verify that the agent has declared a valid intent_id. If not, block execution and return an error: "You must cite a valid active Intent ID."
Phase 2: The Hook Middleware & Security Boundary
Goal: Architect the Hook Engine that wraps all tool execution requests and enforce formal boundaries.
Command Classification: Classify commands as Safe (read) or Destructive (write, delete, execute).
UI-Blocking Authorization: Identify existing logic to pause the Promise chain. Your hook will trigger vscode.window.showWarningMessage with "Approve/Reject" to update core intent evolution. Your architecture should allow defining .intentignore like file to exclude changes to certain intents. A simple model to adopt is a codebase is a collection of intents as much as it is a collection of organized code files linked by imports. You may need to develop or adopt a simple intent language see the following references https://arxiv.org/abs/2406.09757 https://github.com/cbora/aispec http://sunnyday.mit.edu/papers/intent-tse.pdf and those that build formal intent specification structures on top of GitHub speckit.
Autonomous Recovery: If rejected, send a standardized JSON tool-error back to the LLM so it can self-correct without crashing.
Scope Enforcement: In the write_file Pre-Hook, check if the target file matches the owned_scope of the active intent.
If valid: Proceed.
If invalid: Block and return: "Scope Violation: REQ-001 is not authorized to edit [filename]. Request scope expansion."
Phase 3: The AI-Native Git Layer (Full Traceability)
Goal: Implement the semantic tracking ledger. Repay Trust Debt with Verification.
Schema Modification: Modify the write_file tool schema to require intent_id and mutation_class.
Semantic Classification: Ensure your system can distinguish between AST_REFACTOR (syntax change, same intent) and INTENT_EVOLUTION (new feature).
Spatial Hashing: Implement a utility to generate SHA-256 hashes of string content.
Trace Serialization:
Create a Post-Hook on write_file.
Construct the JSON object using the Agent Trace Schema defined before.
Crucial: You must inject the REQ-ID (from Phase 1) into the related array and the content_hash into the ranges object.
Append to agent_trace.jsonl.
Phase 4: Parallel Orchestration (The Master Thinker)
Goal: Manage Silicon Workers via Optimistic Locking.
Concurrency Control:
When an agent attempts to write, calculate the hash of the current file on disk.
Compare it to the hash the agent read when it started its turn.
If they differ: A parallel agent (or human) has modified the file. BLOCK the write to prevent overwriting. Return a "Stale File" error and force the agent to re-read.
Lesson Recording: Implement a tool that appends "Lessons Learned" to CLAUDE.md if a verification step (linter/test) fails.
Proof of Execution (The Demo)
To pass, you must submit a video (max 5 mins) demonstrating the Parallel "Master Thinker" Workflow:
Setup: Open a fresh workspace. Define active_intents.yaml with a simple example of your own - intents generated using GitHub speckit or simple like "INT-001: Build Weather API".
Parallelism: Open two separate instances/chat panels of your extension.
Agent A (Architect): Monitors intent_map.md and defines the plan.
Agent B (Builder): Writes code for INT-001.
The Trace: Have Agent B refactor a file. Show .orchestration/agent_trace.jsonl updating in real-time with the correct AST_REFACTOR classification and content hash.
The Guardrails: Have Agent B try to execute a destructive command or write code without an Intent ID. Show the Pre-Hook blocking it.

Evaluation Rubric
The following criterions will play a significant role in assessing the work you will submit.
Metric
Score 1 (The Vibe Coder)
Score 3 (Competent Tech Lead)
Score 5 (Master Thinker)
Intent-AST Correlation
No machine-readable trace. Relies on standard Git.
Trace file exists but classification is random/inaccurate.
agent_trace.jsonl perfectly maps Intent IDs to Content Hashes. Distinguishes Refactors from Features mathematically.
Context Engineering
State files are handwritten/static. Agent drifts.
Hooks update state, but the architecture is brittle.
Dynamic injection of active_intents.yaml. Agent cannot act without referencing the context DB. Context is curated, not dumped.
Hook Architecture
Logic is stuffed into the main execution loop (spaghetti).
Hooks work but are tightly coupled to the host.
Clean Middleware/Interceptor Pattern. Hooks are isolated, composable, and fail-safe.
Orchestration
Single-threaded only.
Parallel attempts collide.
Parallel Orchestration demonstrated. Shared CLAUDE.md prevents collision. System acts as a "Hive Mind."

# INT-001 — Intent-Code Traceability (Spec)
## Intent
Build an Intent-Code Traceability system for Roo Code that enforces a two-stage reasoning loop and produces durable, auditable traces linking intents to code changes.
## Scope (owned_scope)
- `src/core/assistant-message/**`
- `src/core/tools/**`
- `src/core/hooks/**`
- `src/core/orchestration/**`
- `src/core/prompts/**`
- `.orchestration/**`
## Constraints
- Must enforce **intent selection before any destructive tool** (`write_to_file`, `edit_file`, `apply_diff`, etc.).
- Must keep **privilege separation**: UI emits events; extension host executes privileged actions; hooks are middleware.
- Must log **spatially independent** traces via content hashing.
## Acceptance Criteria
- Agent cannot write code before calling `select_active_intent(intent_id)`.
- When a file is written, a JSONL entry is appended to `.orchestration/agent_trace.jsonl` that includes:
- intent id
- file path
- line range (best-effort)
- `sha256:` content hash of the modified block
- `.orchestration/active_intents.yaml` exists and contains this intent.

# INT-002 — Hook System Implementation
## Intent
Implement a hook system that intercepts tool execution in Roo Code to enforce intent selection and validate AI-generated code before execution.
## Scope (owned_scope)
- `src/core/hooks/**`
- `src/core/assistant-message/presentAssistantMessage.ts`
- `src/core/tools/**`
- `.orchestration/**`
## Constraints
- Must integrate with existing `presentAssistantMessage()` function without breaking current tool execution flow.
- Pre-hooks must run **before** `tool.handle()` is called.
- Post-hooks must run **after** `tool.execute()` completes but before result is returned.
- Hook system must be non-blocking for non-destructive tools (read-only operations).
- Must maintain backward compatibility with existing tools.
## Acceptance Criteria
- `HookEngine` class exists in `src/core/hooks/HookEngine.ts`.
- Pre-hook validates intent selection for destructive tools (`write_to_file`, `edit_file`, `execute_command`, etc.).
- Pre-hook enforces scope validation (file path must be within intent's `owned_scope`).
- Post-hook logs trace entries to `.orchestration/agent_trace.jsonl` for mutating actions.
- `presentAssistantMessage()` integrates `HookEngine` with Pre-Hook and Post-Hook calls.
- All existing tests pass after hook integration.

# INT-003 — Two-Stage Reasoning Loop
## Intent
Implement a two-stage state machine that enforces intent selection before code generation and validates AI output against intent constraints.
## Scope (owned_scope)
- `src/core/hooks/HookEngine.ts`
- `src/core/prompts/sections/tool-use-guidelines.ts`
- `src/core/tools/SelectActiveIntentTool.ts`
- `src/core/task/Task.ts`
## Constraints
- **Stage 1 (Reasoning Intercept):** Agent MUST call `select_active_intent(intent_id)` before any destructive tool.
- **Stage 2 (Contextualized Action):** Agent receives intent context and must include it when making code changes.
- System prompt must enforce this protocol in tool-use guidelines.
- Intent context must be injected into the agent's context before code generation.
## Acceptance Criteria
- System prompt includes instructions requiring `select_active_intent` before code changes.
- `SelectActiveIntentTool` returns XML `<intent_context>` block with scope, constraints, and acceptance criteria.
- Pre-hook blocks destructive tools if no active intent is selected.
- Agent receives intent context in subsequent tool calls.
- Intent context is logged in `agent_trace.jsonl` entries.

# INT-004 — Orchestration Directory Management
## Intent
Implement a robust data model for managing `.orchestration/` directory files with proper initialization, validation, and atomic updates.
## Scope (owned_scope)
- `src/core/orchestration/OrchestrationDataModel.ts`
- `.orchestration/active_intents.yaml`
- `.orchestration/agent_trace.jsonl`
- `.orchestration/intent_map.md`
- `.orchestration/AGENT.md`
## Constraints
- `.orchestration/` directory must be machine-managed (not user-edited directly).
- `active_intents.yaml` must be valid YAML and follow the schema defined in `document.md`.
- `agent_trace.jsonl` must be append-only (no modifications, only appends).
- All file operations must be atomic (write to temp file, then rename).
- Directory and files must be initialized on first use.
## Acceptance Criteria
- `OrchestrationDataModel` class provides methods:
- `initialize()`: Creates directory and initializes files if missing.
- `readActiveIntents()`: Parses and returns active intents.
- `appendAgentTrace()`: Appends trace entry to JSONL file.
- `updateIntentMap()`: Updates intent-to-file mapping.
- `appendAgentKnowledge()`: Appends to AGENT.md.
- All methods handle errors gracefully and log failures.
- Files are created with proper templates if missing.
- YAML parsing validates schema and reports errors clearly.

# INT-005 — Logging & Traceability
## Intent
Implement comprehensive trace logging that links intents to code changes via content hashing, enabling spatial independence and auditability.
## Scope (owned_scope)
- `src/core/hooks/HookEngine.ts` (Post-Hook implementation)
- `src/core/orchestration/OrchestrationDataModel.ts`
- `.orchestration/agent_trace.jsonl`
- `src/utils/git.ts` (for VCS revision tracking)
## Constraints
- Trace entries must include `sha256:` content hash of modified code blocks.
- Line ranges must be best-effort (may be approximate for complex edits).
- Each trace entry must link to:
- Intent ID
- File path (relative to workspace root)
- VCS revision (Git SHA)
- Timestamp
- Model identifier
- Content hashing must be spatially independent (same code block = same hash regardless of file location).
## Acceptance Criteria
- Post-hook computes SHA-256 hash of modified content for file tools.
- Trace entry includes all required fields per `document.md` schema:
- `id` (UUID)
- `timestamp` (ISO 8601)
- `vcs.revision_id` (Git SHA)
- `files[]` with `relative_path`, `conversations[]`, `ranges[]`, `content_hash`
- Trace entries are appended atomically to `agent_trace.jsonl`.
- Content hash format: `sha256:<hex>`.
- Git SHA is retrieved from workspace root (handles non-Git repos gracefully).

# INT-006 — Testing & Validation
## Intent
Create comprehensive test coverage for the Intent-Code Traceability system, including unit tests, integration tests, and end-to-end validation scenarios.
## Scope (owned_scope)
- `src/core/hooks/**/*.test.ts`
- `src/core/orchestration/**/*.test.ts`
- `src/core/tools/SelectActiveIntentTool.test.ts`
- `tests/integration/hook-system.test.ts`
- `tests/e2e/intent-traceability.test.ts`
## Constraints
- Tests must not modify production `.orchestration/` files (use temp directories).
- Tests must be deterministic and isolated (no shared state).
- Integration tests must verify hook system works with real tool execution.
- E2E tests must simulate full agent workflow (intent selection → code change → trace logging).
## Acceptance Criteria
- Unit tests for `HookEngine.preHook()` and `HookEngine.postHook()`.
- Unit tests for `OrchestrationDataModel` file operations.
- Unit tests for `SelectActiveIntentTool` intent loading and context generation.
- Integration test: Verify Pre-Hook blocks destructive tool without intent.
- Integration test: Verify Post-Hook logs trace entry after file write.
- E2E test: Full workflow from intent selection to trace logging.
- All tests pass in CI/CD pipeline.
- Test coverage > 80% for hook and orchestration modules.

## Intent-Driven Architecture (Reasoning Loop)
You are an Intent-Driven Architect. You CANNOT write code immediately. Your first action MUST be to analyze the user request and call select_active_intent(intent_id) to load the necessary context.
**CRITICAL PROTOCOL:**
1. When the user requests code changes (refactoring, new features, bug fixes), you MUST first:
- Analyze the request to identify which intent it relates to
- Call select_active_intent(intent_id) with a valid intent ID from active_intents.yaml
- Wait for the intent context to be loaded
- Only then proceed with code changes
2. You CANNOT use write_to_file, edit_file, apply_diff, or any other code modification tools without first calling select_active_intent.
3. If you attempt to write code without selecting an intent, the system will block your action and return an error.
4. The intent context will provide you with:
- Owned scope (which files/directories you can modify)
- Constraints (rules you must follow)
- Acceptance criteria (definition of done)
## General Tool Use
1. Assess what information you already have and what information you need to proceed with the task.
2. Choose the most appropriate tool based on the task and the tool descriptions provided. Assess if you need additional information to proceed, and which of the available tools would be most effective for gathering this information. For example using the list_files tool is more effective than running a command like \`ls\` in the terminal. It's critical that you think about each available tool and use the one that best fits the current step in the task.
3. If multiple actions are needed, you may use multiple tools in a single message when appropriate, or use tools iteratively across messages. Each tool use should be informed by the results of previous tool uses. Do not assume the outcome of any tool use. Each step must be informed by the previous step's result.
