This makes adding dry-run to new handlers error-prone and the existing code confusing.\n\n**Goal:** Single mechanism where the engine routes to `simulate()` or `execute()` based on `services.dry_run`. Each handler optionally overrides `simulate()` for custom behavior.\n\n## Design\n\n### New abstractions\n\n1. **`Outcome::simulated(node_id)`** — factory returning `Success` with `notes: \"[Simulated] {node_id}\"`\n2. **`Handler::simulate()`** — trait method with default returning `Outcome::simulated(&node.id)`\n3. **`dispatch_handler()`** — free function in `handler/mod.rs` that calls `simulate()` or `execute()` based on `services.dry_run`\n\n### Dispatch change\n\nReplace direct `handler.execute()` calls with `dispatch_handler()` at two sites:\n- `engine.rs:964` — in `execute_with_retry()`\n- `parallel.rs:439` — child handler dispatch in spawned tasks\n\n### Handler simulate() overrides\n\n| Handler | Override? | Behavior |\n|---|---|---|\n| Start, Exit, Conditional | No | Default: generic `[Simulated]` success |\n| **WaitHandler** | No | Default: instant success, **no sleep** |\n| **CommandHandler** | Yes | Empty `command.output`/`command.stderr` context updates + note with script text |\n| **AgentHandler** | Yes | `last_stage`, `last_response`, `response.{id}` context updates with simulated text |\n| **PromptHandler** | Yes | Same as Agent — simulated response context updates |\n| **FanInHandler** | Yes | Call `heuristic_select()` directly (no LLM, no git merge) |\n| **HumanHandler** | Yes | Auto-select first choice, set `human.gate.selected`/`human.gate.label` + `suggested_next_ids` |\n| **ParallelHandler** | Yes | Find join node → set `jump_to_node`, set `parallel.branch_count`, dispatch children via `dispatch_handler()`, skip all git worktree ops |\n| SubWorkflowHandler | No | Default. Already propagates `dry_run` to child engine's `RunConfig`; child engine will use `dispatch_handler()` automatically |\n\n### Cleanup from execute()\n\n- **CommandHandler**: remove `if services.dry_run { ... }` block (move logic to `simulate()`)\n- **AgentHandler/PromptHandler/FanInHandler**: leave `backend=None` paths as-is for now (they become unreachable during dry-run but serve as error fallback). Making backend non-optional is a separate follow-up.\n\n## Files to modify\n\n1. `lib/crates/fabro-workflows/src/outcome.rs` — add `Outcome::simulated()`\n2. `lib/crates/fabro-workflows/src/handler/mod.rs` — add `simulate()` to trait, add `dispatch_handler()`\n3. `lib/crates/fabro-workflows/src/engine.rs` — use `dispatch_handler()` in `execute_with_retry()` (~line 964)\n4. `lib/crates/fabro-workflows/src/handler/command.rs` — move dry-run block to `simulate()`, remove from `execute()`\n5. `lib/crates/fabro-workflows/src/handler/agent.rs` — add `simulate()` override\n6. `lib/crates/fabro-workflows/src/handler/prompt.rs` — add `simulate()` override\n7. `lib/crates/fabro-workflows/src/handler/fan_in.rs` — add `simulate()` override\n8. `lib/crates/fabro-workflows/src/handler/human.rs` — add `simulate()` override\n9. `lib/crates/fabro-workflows/src/handler/parallel.rs` — add `simulate()` override, use `dispatch_handler()` for child dispatch\n\n## Tests\n\n- Test `dispatch_handler()` routes to `simulate()` when `dry_run=true`, `execute()` when `false`\n- Test each handler's `simulate()` returns expected context updates\n- Update existing `dry_run_skips_execution` test in command.rs to test `simulate()` directly\n- Update `codergen_handler_simulation_mode` in agent.rs\n- Update `prompt_handler_simulation_mode` in prompt.rs\n\n## Verification\n\n```bash\ncargo test -p fabro-workflows # all tests pass\ncargo clippy -p fabro-workflows --tests -- -D warnings # no new warnings\nfabro run --dry-run # workflow completes instantly, no real execution\n```\n\n\n## Completed stages\n- **toolchain**: success\n - Script: `command -v cargo >/dev/null || { curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y && sudo ln -sf $HOME/.cargo/bin/* /usr/local/bin/; }; cargo --version 2>&1`\n - Stdout:\n ```\n cargo 1.94.0 (85eff7c80 2026-01-15)\n ```\n - Stderr: (empty)\n- **preflight_compile**: success\n - Script: `cargo check 2>&1`\n - Stdout:\n ```\n Updating crates.io index\n

This makes adding dry-run to new handlers error-prone and the existing code confusing.\n\n**Goal:** Single mechanism where the engine routes to `simulate()` or `execute()` based on `services.dry_run`.

`lib/crates/fabro-workflows/src/handler/mod.rs` — add `simulate()` to trait, add `dispatch_handler()`\n3. `lib/crates/fabro-workflows/src/engine.rs` — use `dispatch_handler()` in `execute_with_retry()` (~line 964)\n4. `lib/crates/fabro-workflows/src/handler/command.rs` — move dry-run block to `simulate()`, remove from `execute()`\n5. `lib/crates/fabro-workflows/src/handler/agent.rs` — add `simulate()` override\n6. `lib/crates/fabro-workflows/src/handler/prompt.rs` — add `simulate()` override\n7. `lib/crates/fabro-workflows/src/handler/fan_in.rs` — add `simulate()` override\n8. `lib/crates/fabro-workflows/src/handler/human.rs` — add `simulate()` override\n9. `lib/crates/fabro-workflows/src/handler/parallel.rs` — add `simulate()` override, use `dispatch_handler()` for child dispatch\n\n## Tests\n\n- Test `dispatch_handler()` routes to `simulate()` when `dry_run=true`, `execute()` when `false`\n- Test each handler's `simulate()` returns expected context updates\n- Update existing `dry_run_skips_execution` test in command.rs to test `simulate()` directly\n- Update `codergen_handler_simulation_mode` in agent.rs\n- Update `prompt_handler_simulation_mode` in prompt.rs\n\n## Verification\n\n```bash\ncargo test -p fabro-workflows # all tests pass\ncargo clippy -p fabro-workflows --tests -- -D warnings # no new warnings\nfabro run --dry-run # workflow completes instantly, no real execution\n```\n\n\n## Completed stages\n- **toolchain**: success\n - Script: `command -v cargo >/dev/null || { curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y && sudo ln -sf $HOME/.cargo/bin/* /usr/local/bin/; }; cargo --version 2>&1`\n - Stdout:\n ```\n cargo 1.94.0 (85eff7c80 2026-01-15)\n ```\n - Stderr: (empty)\n- **preflight_compile**: success\n - Script: `cargo check 2>&1`\n - Stdout:\n ```\n Updating crates.io index\n

Let me provide a summary of everything that was implemented:\n\n## Summary of Changes\n\n### 1. `outcome.rs` — Added `Outcome::simulated()`\n- New factory method `Outcome::simulated(node_id)` returning `Success` with `notes: \"[Simulated] {node_id}\"`\n- Added test `outcome_simulated_factory`\n\n### 2. `handler/mod.rs` — Added `simulate()` to trait + `dispatch_handler()`\n- Added `Handler::simulate()` trait method with default implementation returning `Outcome::simulated(&node.id)`\n- Added `dispatch_handler()` free function that routes to `simulate()` when `services.dry_run` is true, otherwise `execute()`\n- Added tests: `dispatch_handler_routes_to_simulate_when_dry_run`, `dispatch_handler_routes_to_execute_when_not_dry_run`\n\n### 3. `engine.rs` — Dispatch change\n- Replaced `handler.execute(...)` with `crate::handler::dispatch_handler(handler, ...)` in `execute_with_retry()`\n\n### 4. `handler/command.rs` — Moved dry-run to `simulate()`\n- Added `simulate()` override with empty `command.output`/`command.stderr` context updates + note with script text\n- Removed `if services.dry_run { ... }` block from `execute()`\n- Updated test `dry_run_skips_execution` → `simulate_skips_execution` (tests `simulate()` directly)\n- Added test `dispatch_routes_to_simulate_in_dry_run`\n\n### 5. `handler/agent.rs` — Added `simulate()` override\n- Sets `last_stage`, `last_response`, `response.{id}` context updates with simulated text\n- Updated test `codergen_handler_simulation_mode` → `codergen_handler_simulate`\n\n### 6. `handler/prompt.rs` — Added `simulate()` override\n- Same context updates as agent handler (simulated response)\n- Updated test `prompt_handler_simulation_mode` → `prompt_handler_simulate`\n\n### 7. `handler/fan_in.rs` — Added `simulate()` override\n- Calls `heuristic_select()` directly (no LLM, no git merge)\n- Added test `fan_in_simulate_uses_heuristic`\n\n### 8. `handler/human.rs` — Added `simulate()` override\n- Auto-selects first choice from outgoing edges\n- Sets `human.gate.selected`, `human.gate.label`, and `suggested_next_ids`\n- Added test `simulate_selects_first_choice`\n\n### 9. `handler/parallel.rs` — Added `simulate()` override + dispatch change\n- Finds join node → sets `jump_to_node`; sets `parallel.branch_count`; dispatches children via `dispatch_handler()` (which recurses into their `simulate()`); skips all git worktree ops\n- Updated child dispatch in `execute()` to use `dispatch_handler()`\n- Added test `parallel_handler_simulate`\n\n### Handlers using default `simulate()` (no override needed)\n- **Start, Exit, Conditional, Wait**: Use default generic `[Simulated]` success — WaitHandler no longer sleeps during dry-run\n- **SubWorkflowHandler**: Uses default; already propagates `dry_run` to child engine via `RunConfig`", "failure_class": "", - "internal.node_visit_count": 1, "internal.retry_count.preflight_lint": 1, - "failure_signature": "", - "last_response": "All changes are correct.

Fix any issues found. + +## Phase 1: Identify Changes + +Run git diff (or git diff HEAD if there are staged changes) to see what changed. If there are no git changes, review the most recently modified files that the user mentioned or that you edited earlier in this conversation. + +## Phase 2: Launch Three Review Agents in Parallel + +Use the Agent tool to launch all three agents concurrently in a single message. Pass each agent the full diff so it has the complete context. + +### Agent 1: Code Reuse Review + +For each change: + +1. Search for existing utilities and helpers that could replace newly written code. Use Grep to find similar patterns elsewhere in the codebase — common locations are utility directories, shared modules, and files adjacent to the changed ones. +2. Flag any new function that duplicates existing functionality. Suggest the existing function to use instead. +3. Flag any inline logic that could use an existing utility — hand-rolled string manipulation, manual path handling, custom environment checks, ad-hoc type guards, and similar patterns are common candidates. + +### Agent 2: Code Quality Review + +Review the same changes for hacky patterns: + +1. Redundant state: state that duplicates existing state, cached values that could be derived, observers/effects that could be direct calls +2. Parameter sprawl: adding new parameters to a function instead of generalizing or restructuring existing ones +3. Copy-paste with slight variation: near-duplicate code blocks that should be unified with a shared abstraction +4. Leaky abstractions: exposing internal details that should be encapsulated, or breaking existing abstraction boundaries +5. Stringly-typed code: using raw strings where constants, enums (string unions), or branded types already exist in the codebase + +### Agent 3: Efficiency Review + +Review the same changes for efficiency: + +1. Unnecessary work: redundant computations, repeated file reads, duplicate network/API calls, N+1 patterns +2. Missed concurrency: independent operations run sequentially when they could run in parallel +3. Hot-path bloat: new blocking work added to startup or per-request/per-render hot paths +4. Unnecessary existence checks: pre-checking file/resource existence before operating (TOCTOU anti-pattern) — operate directly and handle the error +5. Memory: unbounded data structures, missing cleanup, event listener leaks +6. Overly broad operations: reading entire files when only a portion is needed, loading all items when filtering for one + +## Phase 3: Fix Issues + +Wait for all three agents to complete. Aggregate their findings and fix each issue directly. If a finding is a false positive or not worth addressing, note it and move on — do not argue with the finding, just skip it. + +When done, briefly summarize what was fixed (or confirm the code was already clean). \ No newline at end of file diff --git a/nodes/simplify/provider_used.json b/nodes/simplify/provider_used.json new file mode 100644 index 000000000..c1905ff10 --- /dev/null +++ b/nodes/simplify/provider_used.json @@ -0,0 +1,5 @@ +{ + "mode": "agent", + "provider": "anthropic", + "model": "claude-opus-4-6" +} \ No newline at end of file diff --git a/nodes/simplify/response.md b/nodes/simplify/response.md new file mode 100644 index 000000000..e416c5402 --- /dev/null +++ b/nodes/simplify/response.md @@ -0,0 +1,21 @@ +## Summary of Changes + +All three review agents completed. Here's what was found and fixed: + +### Issues Fixed + +1. **Copy-paste duplication between `AgentHandler::simulate()` and `PromptHandler::simulate()`** — The two implementations were byte-for-byte identical (building `simulated_text`, setting `LAST_STAGE`, `LAST_RESPONSE`, `response_key`). Extracted a shared `simulate_llm_handler(node)` helper in `agent.rs` that both handlers now delegate to. + +2. **Inconsistent `Outcome::success()` vs `Outcome::simulated()` in `CommandHandler::simulate()`** — Every other handler used `Outcome::simulated(&node.id)` as the base, but `CommandHandler` used `Outcome::success()` and manually set notes. Changed to use `Outcome::simulated()` for consistency (the custom notes string is still applied afterward). + +3. **Missing trailing newlines in all 9 changed files** — The original implement commit stripped trailing newlines from every file it touched. Restored them all. + +4. **Clarifying comment in `FanInHandler::simulate()`** — Added a comment noting that the `Outcome::simulated()` notes are intentionally overridden with handler-specific detail. + +### Findings Not Actioned (correctly skipped) + +- **ParallelHandler::simulate() runs branches sequentially** — Not a problem. Simulate is pure in-memory work (sub-microsecond per branch), parallelism would add overhead. +- **`truncate()` call on always-short string** — Negligible cost (fast-path no-op comparison). +- **`dispatch_handler()` overhead** — One boolean check per handler invocation; negligible vs. the handler work itself. +- **`shell_quote()` duplication across crates** — Pre-existing, not introduced by this diff. +- **Pre-existing clippy warning in `cli/pr.rs`** — Not related to this change. \ No newline at end of file diff --git a/nodes/simplify/status.json b/nodes/simplify/status.json new file mode 100644 index 000000000..0613a7f8c --- /dev/null +++ b/nodes/simplify/status.json @@ -0,0 +1,6 @@ +{ + "status": "success", + "notes": "Stage completed: simplify", + "failure_reason": null, + "timestamp": "2026-03-15T23:18:57.187491+00:00" +} \ No newline at end of file
