Steps use checkbox (`- [ ]`) syntax for tracking.\n\n**Goal:** Add `output_schema` validation for agent and prompt nodes, with context-preserving repair turns when structured output does not validate.\n\n**Architecture:** Introduce a small structured-output layer in `fabro-workflow` that resolves node-level schema declarations, extracts JSON output, validates it, and produces either routing side effects or a parsed custom output context update. Agent and prompt execution must perform schema repair inside the active LLM conversation instead of using the workflow executor retry path.\n\n**Tech Stack:** Rust, Graphviz workflow attrs, `serde_json`, workspace `jsonschema`, existing `fabro-llm::ResponseFormat`, Fabro agent sessions, `cargo nextest`.\n\n---\n\n## Public Interface\n\nWorkflow authors can opt in on agent and prompt nodes:\n\n```dot\nreview [\n shape=tab,\n output_schema=\"routing\",\n output_retries=2\n]\n\naudit [\n shape=tab,\n output_schema=\"@schemas/audit-result.schema.json\",\n output_retries=2\n]\n```\n\n- `output_schema=\"routing\"` uses Fabro's built-in routing directive schema.\n- `output_schema=\"@path/to/schema.json\"` loads a JSON Schema file through existing workflow file-reference rules.\n- `output_retries` controls corrective turns inside the same node execution. Default: `2`. `0` means validate once and fail without a repair turn.\n- Schema failures are terminal node failures after `output_retries` is exhausted. They are not `retry_requested` outcomes and do not consume `max_retries`.\n- `backend=\"acp\"` with `output_schema` is unsupported in v1 and returns a clear validation error.\n\n## Implementation Tasks\n\n### Task 1: Node Attributes And File Reference Resolution\n\n**Files:**\n- Modify: `lib/crates/fabro-types/src/graph.rs`\n- Modify: `lib/crates/fabro-workflow/src/static_reference.rs`\n- Modify: `lib/crates/fabro-workflow/src/transforms/file_inlining.rs`\n- Test: existing unit tests in those files\n\n- [ ] Add `Node::output_schema(&self) -> Option<&str>` next to other agent/prompt attrs.\n- [ ] Add `Node::output_retries(&self) -> i64` returning `self.int_attr(\"output_retries\").unwrap_or(2).max(0)`.\n- [ ] Teach static reference validation that node attr `output_schema` values starting with `@` are file inline references.\n- [ ] Extend file inlining so `output_schema=\"@schemas/foo.json\"` is replaced with the schema file contents before execution, while `output_schema=\"routing\"` stays unchanged.\n- [ ] Add tests for absent attrs, default retries, zero retries, file inlining, and unresolved schema reference diagnostics.\n\nRun:\n\n```bash\ncargo nextest run -p fabro-types -p fabro-workflow graph:: file_inlining static_reference\n```\n\nExpected: targeted tests pass.\n\n### Task 2: Structured Output Module\n\n**Files:**\n- Create: `lib/crates/fabro-workflow/src/handler/structured_output.rs`\n- Modify: `lib/crates/fabro-workflow/src/handler/mod.rs`\n- Modify: `lib/crates/fabro-workflow/Cargo.toml`\n- Test: unit tests in `structured_output.rs`\n\n- [ ] Add `jsonschema.workspace = true` to `fabro-workflow` dependencies.\n- [ ] Define `OutputSchemaKind` with `Routing` and `JsonSchema { schema: serde_json::Value }`.\n- [ ] Parse `node.output_schema()` into `None`, `Routing`, or custom JSON Schema. Treat literal `routing` as the only built-in keyword.\n- [ ] Add a built-in routing schema requiring an object with at least one recognized field: `preferred_next_label`, `outcome`, `failure_reason`, `suggested_next_ids`, or `context_updates`.\n- [ ] Reuse balanced-object scanning semantics for response text: validate the last JSON object that is relevant to the selected schema.\n- [ ] Return a structured validation result containing the parsed JSON object, concise error messages, and enough information to build a repair prompt.\n- [ ] Add tests for valid routing JSON, missing routing fields, wrong routing field types, valid custom schema, invalid custom schema, invalid JSON, and no JSON object.\n\nRun:\n\n```bash\ncargo nextest run -p fabro-workflow structured_output\n```\n\nExpected: structured-output unit tests pass.\n\n### Task 3: Routing Extraction Compatibility\n\n**Files:**\n- Modify: `lib/crates/fabro-workflow/src/handler/agent.rs`\n- Test: existing agent handler unit tests\n\n- [ ] Keep the loose default unchanged when `output_schema` is absent.\n- [ ] Move current `STATUS_FIELDS`, balanced JSON scanning, and routing-field application behind reusable functions in `structured_output.rs` or call the new module from `agent.rs`.\n- [ ] For `output_schema=\"routing\"`, require schema-valid routing JSON and surface validation failures for repair instead of silently ignoring bad candidates.\n- [ ] Preserve existing routing fallback priority for agent nodes: response text first, then `status.json`, then last file touched.\n- [ ] Keep prompt-node routing behavior response-only unless later tasks explicitly add prompt `status.json` support.\n\nRun:\n\n```bash\ncargo nextest run -p fabro-workflow handler::agent\n```\n\nExpected: existing loose routing tests still pass, plus new strict routing tests pass.\n\n### Task 4: Prompt Node Same-Context Repair\n\n**Files:**\n- Modify: `lib/crates/fabro-workflow/src/handler/llm/api.rs`\n- Modify: `lib/crates/fabro-workflow/src/handler/prompt.rs`\n- Test: prompt/API backend tests in those files\n\n- [ ] In `AgentApiBackend::one_shot`, keep `messages` mutable across attempts.\n- [ ] When a prompt node has a custom JSON Schema, set `response_format=JsonSchema` on the initial and repair LLM requests. For `routing`, use `JsonObject` or no provider-native schema if provider behavior would conflict with Fabro's routing extraction.\n- [ ] After each LLM response, validate according to `output_schema`.\n- [ ] On validation failure with repair attempts remaining, append `Message::assistant(response.text())`, then append a corrective `Message::user(repair_message)`, and call `client.complete` again with the same messages.\n- [ ] On success, return the validated response text and aggregate usage across all attempts.\n- [ ] On exhaustion, return a terminal failed outcome with failure reason `output schema validation failed after N repair attempt(s)`.\n- [ ] Update `PromptHandler` so validated custom output is added to `context_updates[\"output.{node_id}\"]`; routing output still updates outcome routing fields.\n\nRun:\n\n```bash\ncargo nextest run -p fabro-workflow handler::prompt handler::llm::api\n```\n\nExpected: prompt repair keeps previous assistant output in the message list and succeeds after a corrective response.\n\n### Task 5: Agent Node Same-Session Repair\n\n**Files:**\n- Modify: `lib/crates/fabro-workflow/src/handler/llm/api.rs`\n- Modify: `lib/crates/fabro-workflow/src/handler/agent.rs`\n- Test: agent/API backend tests in those files\n\n- [ ] In `AgentApiBackend::run`, validate the final assistant response before releasing, closing, or caching the session.\n- [ ] On validation failure with repair attempts remaining, call `session.process_input(repair_message)` on the same `Session`.\n- [ ] Recompute the final assistant response after each repair turn from `session.history()`.\n- [ ] Aggregate usage across all new assistant turns, including repair turns, without double-counting reused session history.\n- [ ] Do not set provider-native `response_format` for agent sessions in v1, because agent sessions may need normal tool-use messages before final output.\n- [ ] Return terminal failure after exhaustion; do not return a retryable backend error and do not request workflow node retry.\n- [ ] Update `AgentHandler` to apply validated routing/custom output to the final `Outcome`.\n\nRun:\n\n```bash\ncargo nextest run -p fabro-workflow handler::agent handler::llm::api\n```\n\nExpected: agent repair sends a second `process_input` to the same session and final validated output drives outcome/context updates.\n\n### Task 6: ACP Guardrail\n\n**Files:**\n- Modify: `lib/crates/fabro-workflow/src/handler/llm/acp.rs`\n- Test: ACP backend tests in that file\n\n- [ ] At the start of `AgentAcpBackend::run`, reject nodes where `node.output_schema().is_some()`.\n- [ ] Use a clear error message: `output_schema is not supported with backend=\"acp\" in this release`.\n- [ ] Add a test proving the ACP backend does not launch a process when `output_schema` is present.\n\nRun:\n\n```bash\ncargo nextest run -p fabro-workflow handler::llm::acp\n```\n\nExpected: ACP guardrail test passes.\n\n### Task 7: Docs\n\n**Files:**\n- Modify: `docs/public/agents/outputs.mdx`\n- Modify: `docs/public/reference/dot-language.mdx`\n\n- [ ] Document `output_schema=\"routing\"` and `output_schema=\"@schema.json\"` under routing/structured outputs.\n- [ ] Document same-context repair behavior explicitly: Fabro sends validation feedback to the same agent/prompt context before failing.\n- [ ] Document `output_retries`, default `2`, and distinction from `max_retries`.\n- [ ] Document v1 scope: agent/prompt nodes only; ACP unsupported; custom schema output stored at `output.{node_id}`.\n\nRun:\n\n```bash\nrg -n \"output_schema|output_retries|output\\\\.\" docs/public/agents/outputs.mdx docs/public/reference/dot-language.mdx\n```\n\nExpected: docs mention the new attrs and storage behavior.\n\n### Task 8: Full Verification\n\n**Files:**\n- No new files beyond prior tasks\n\n- [ ] Run focused workflow tests:\n\n```bash\ncargo nextest run -p fabro-workflow\n```\n\n- [ ] Run formatting check:\n\n```bash\ncargo +nightly-2026-04-14 fmt --check --all\n```\n\n- [ ] Run clippy:\n\n```bash\ncargo +nightly-2026-04-14 clippy --workspace --all-targets -- -D warnings\n```\n\n- [ ] If snapshots change, inspect before accepting:\n\n```bash\ncargo insta pending-snapshots\n```\n\nOnly run `cargo insta accept` after verifying every pending snapshot is expected.\n\n## Acceptance Criteria\n\n- Existing workflows without `output_schema` behave exactly as before.\n- `output_schema=\"routing\"` prevents malformed/missing routing JSON from silently falling through to normal edge selection.\n- Invalid structured output results in a corrective LLM turn in the same context window.\n- Prompt repair preserves previous assistant output in the message list.\n- Agent repair preserves the same live session and does not re-run the node from scratch.\n- Exhausted output repair attempts produce a clear terminal failure.\n- Custom schema output is available to downstream nodes at `output.{node_id}`.\n- Docs clearly distinguish `output_retries` from `max_retries`.\n\n## Assumptions\n\n- `output_retries=2` is the default.\n- Custom schema validation targets the final JSON object in the response text.\n- `status.json` fallback remains routing-specific.\n- Provider-native response schema is used for prompt nodes only where it is safe.\n- ACP support can be added later after there is a guaranteed context-preserving repair mechanism.\n", + "thread.simplify_gpt.current_node": "verify", + "thread.simplify_opus.current_node": "simplify_gpt", + "internal.retry_count.implement": 0, + "failure_signature": "verify|deterministic|script failed with exit code: ## output from https://github.com/fabro-sh/fabro * branch main -> fetch_head .. main -> origin/main committer identity unknown *** please tell me who you are. run git config --global user.email \"y" + }, + "node_outcomes": { + "toolchain": { + "status": "succeeded", + "context_updates": { + "command.output": "blob://sha256/fc14b2ba2d770e5cd3169df7a29525c962adfc4cfa3097b9098c63ebd61a748c" + }, + "notes": "Script completed: 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/;

Steps use checkbox (`- [ ]`) syntax for tracking.\n\n**Goal:** Add `output_schema` validation for agent and prompt nodes, with context-preserving repair turns when structured output does not validate.\n\n**Architecture:** Introduce a small structured-output layer in `fabro-workflow` that resolves node-level schema declarations, extracts JSON output, validates it, and produces either routing side effects or a parsed custom output context update. Agent and prompt execution must perform schema repair inside the active LLM conversation instead of using the workflow executor retry path.\n\n**Tech Stack:** Rust, Graphviz workflow attrs, `serde_json`, workspace `jsonschema`, existing `fabro-llm::ResponseFormat`, Fabro agent sessions, `cargo nextest`.\n\n---\n\n## Public Interface\n\nWorkflow authors can opt in on agent and prompt nodes:\n\n```dot\nreview [\n shape=tab,\n output_schema=\"routing\",\n output_retries=2\n]\n\naudit [\n shape=tab,\n output_schema=\"@schemas/audit-result.schema.json\",\n output_retries=2\n]\n```\n\n- `output_schema=\"routing\"` uses Fabro's built-in routing directive schema.\n- `output_schema=\"@path/to/schema.json\"` loads a JSON Schema file through existing workflow file-reference rules.\n- `output_retries` controls corrective turns inside the same node execution. Default: `2`. `0` means validate once and fail without a repair turn.\n- Schema failures are terminal node failures after `output_retries` is exhausted. They are not `retry_requested` outcomes and do not consume `max_retries`.\n- `backend=\"acp\"` with `output_schema` is unsupported in v1 and returns a clear validation error.\n\n## Implementation Tasks\n\n### Task 1: Node Attributes And File Reference Resolution\n\n**Files:**\n- Modify: `lib/crates/fabro-types/src/graph.rs`\n- Modify: `lib/crates/fabro-workflow/src/static_reference.rs`\n- Modify: `lib/crates/fabro-workflow/src/transforms/file_inlining.rs`\n- Test: existing unit tests in those files\n\n- [ ] Add `Node::output_schema(&self) -> Option<&str>` next to other agent/prompt attrs.\n- [ ] Add `Node::output_retries(&self) -> i64` returning `self.int_attr(\"output_retries\").unwrap_or(2).max(0)`.\n- [ ] Teach static reference validation that node attr `output_schema` values starting with `@` are file inline references.\n- [ ] Extend file inlining so `output_schema=\"@schemas/foo.json\"` is replaced with the schema file contents before execution, while `output_schema=\"routing\"` stays unchanged.\n- [ ] Add tests for absent attrs, default retries, zero retries, file inlining, and unresolved schema reference diagnostics.\n\nRun:\n\n```bash\ncargo nextest run -p fabro-types -p fabro-workflow graph:: file_inlining static_reference\n```\n\nExpected: targeted tests pass.\n\n### Task 2: Structured Output Module\n\n**Files:**\n- Create: `lib/crates/fabro-workflow/src/handler/structured_output.rs`\n- Modify: `lib/crates/fabro-workflow/src/handler/mod.rs`\n- Modify: `lib/crates/fabro-workflow/Cargo.toml`\n- Test: unit tests in `structured_output.rs`\n\n- [ ] Add `jsonschema.workspace = true` to `fabro-workflow` dependencies.\n- [ ] Define `OutputSchemaKind` with `Routing` and `JsonSchema { schema: serde_json::Value }`.\n- [ ] Parse `node.output_schema()` into `None`, `Routing`, or custom JSON Schema. Treat literal `routing` as the only built-in keyword.\n- [ ] Add a built-in routing schema requiring an object with at least one recognized field: `preferred_next_label`, `outcome`, `failure_reason`, `suggested_next_ids`, or `context_updates`.\n- [ ] Reuse balanced-object scanning semantics for response text: validate the last JSON object that is relevant to the selected schema.\n- [ ] Return a structured validation result containing the parsed JSON object, concise error messages, and enough information to build a repair prompt.\n- [ ] Add tests for valid routing JSON, missing routing fields, wrong routing field types, valid custom schema, invalid custom schema, invalid JSON, and no JSON object.\n\nRun:\n\n```bash\ncargo nextest run -p fabro-workflow structured_output\n```\n\nExpected: structured-output unit tests pass.\n\n### Task 3: Routing Extraction Compatibility\n\n**Files:**\n- Modify: `lib/crates/fabro-workflow/src/handler/agent.rs`\n- Test: existing agent handler unit tests\n\n- [ ] Keep the loose default unchanged when `output_schema` is absent.\n- [ ] Move current `STATUS_FIELDS`, balanced JSON scanning, and routing-field application behind reusable functions in `structured_output.rs` or call the new module from `agent.rs`.\n- [ ] For `output_schema=\"routing\"`, require schema-valid routing JSON and surface validation failures for repair instead of silently ignoring bad candidates.\n- [ ] Preserve existing routing fallback priority for agent nodes: response text first, then `status.json`, then last file touched.\n- [ ] Keep prompt-node routing behavior response-only unless later tasks explicitly add prompt `status.json` support.\n\nRun:\n\n```bash\ncargo nextest run -p fabro-workflow handler::agent\n```\n\nExpected: existing loose routing tests still pass, plus new strict routing tests pass.\n\n### Task 4: Prompt Node Same-Context Repair\n\n**Files:**\n- Modify: `lib/crates/fabro-workflow/src/handler/llm/api.rs`\n- Modify: `lib/crates/fabro-workflow/src/handler/prompt.rs`\n- Test: prompt/API backend tests in those files\n\n- [ ] In `AgentApiBackend::one_shot`, keep `messages` mutable across attempts.\n- [ ] When a prompt node has a custom JSON Schema, set `response_format=JsonSchema` on the initial and repair LLM requests. For `routing`, use `JsonObject` or no provider-native schema if provider behavior would conflict with Fabro's routing extraction.\n- [ ] After each LLM response, validate according to `output_schema`.\n- [ ] On validation failure with repair attempts remaining, append `Message::assistant(response.text())`, then append a corrective `Message::user(repair_message)`, and call `client.complete` again with the same messages.\n- [ ] On success, return the validated response text and aggregate usage across all attempts.\n- [ ] On exhaustion, return a terminal failed outcome with failure reason `output schema validation failed after N repair attempt(s)`.\n- [ ] Update `PromptHandler` so validated custom output is added to `context_updates[\"output.{node_id}\"]`; routing output still updates outcome routing fields.\n\nRun:\n\n```bash\ncargo nextest run -p fabro-workflow handler::prompt handler::llm::api\n```\n\nExpected: prompt repair keeps previous assistant output in the message list and succeeds after a corrective response.\n\n### Task 5: Agent Node Same-Session Repair\n\n**Files:**\n- Modify: `lib/crates/fabro-workflow/src/handler/llm/api.rs`\n- Modify: `lib/crates/fabro-workflow/src/handler/agent.rs`\n- Test: agent/API backend tests in those files\n\n- [ ] In `AgentApiBackend::run`, validate the final assistant response before releasing, closing, or caching the session.\n- [ ] On validation failure with repair attempts remaining, call `session.process_input(repair_message)` on the same `Session`.\n- [ ] Recompute the final assistant response after each repair turn from `session.history()`.\n- [ ] Aggregate usage across all new assistant turns, including repair turns, without double-counting reused session history.\n- [ ] Do not set provider-native `response_format` for agent sessions in v1, because agent sessions may need normal tool-use messages before final output.\n- [ ] Return terminal failure after exhaustion; do not return a retryable backend error and do not request workflow node retry.\n- [ ] Update `AgentHandler` to apply validated routing/custom output to the final `Outcome`.\n\nRun:\n\n```bash\ncargo nextest run -p fabro-workflow handler::agent handler::llm::api\n```\n\nExpected: agent repair sends a second `process_input` to the same session and final validated output drives outcome/context updates.\n\n### Task 6: ACP Guardrail\n\n**Files:**\n- Modify: `lib/crates/fabro-workflow/src/handler/llm/acp.rs`\n- Test: ACP backend tests in that file\n\n- [ ] At the start of `AgentAcpBackend::run`, reject nodes where `node.output_schema().is_some()`.\n- [ ] Use a clear error message: `output_schema is not supported with backend=\"acp\" in this release`.\n- [ ] Add a test proving the ACP backend does not launch a process when `output_schema` is present.\n\nRun:\n\n```bash\ncargo nextest run -p fabro-workflow handler::llm::acp\n```\n\nExpected: ACP guardrail test passes.\n\n### Task 7: Docs\n\n**Files:**\n- Modify: `docs/public/agents/outputs.mdx`\n- Modify: `docs/public/reference/dot-language.mdx`\n\n- [ ] Document `output_schema=\"routing\"` and `output_schema=\"@schema.json\"` under routing/structured outputs.\n- [ ] Document same-context repair behavior explicitly: Fabro sends validation feedback to the same agent/prompt context before failing.\n- [ ] Document `output_retries`, default `2`, and distinction from `max_retries`.\n- [ ] Document v1 scope: agent/prompt nodes only; ACP unsupported; custom schema output stored at `output.{node_id}`.\n\nRun:\n\n```bash\nrg -n \"output_schema|output_retries|output\\\\.\" docs/public/agents/outputs.mdx docs/public/reference/dot-language.mdx\n```\n\nExpected: docs mention the new attrs and storage behavior.\n\n### Task 8: Full Verification\n\n**Files:**\n- No new files beyond prior tasks\n\n- [ ] Run focused workflow tests:\n\n```bash\ncargo nextest run -p fabro-workflow\n```\n\n- [ ] Run formatting check:\n\n```bash\ncargo +nightly-2026-04-14 fmt --check --all\n```\n\n- [ ] Run clippy:\n\n```bash\ncargo +nightly-2026-04-14 clippy --workspace --all-targets -- -D warnings\n```\n\n- [ ] If snapshots change, inspect before accepting:\n\n```bash\ncargo insta pending-snapshots\n```\n\nOnly run `cargo insta accept` after verifying every pending snapshot is expected.\n\n## Acceptance Criteria\n\n- Existing workflows without `output_schema` behave exactly as before.\n- `output_schema=\"routing\"` prevents malformed/missing routing JSON from silently falling through to normal edge selection.\n- Invalid structured output results in a corrective LLM turn in the same context window.\n- Prompt repair preserves previous assistant output in the message list.\n- Agent repair preserves the same live session and does not re-run the node from scratch.\n- Exhausted output repair attempts produce a clear terminal failure.\n- Custom schema output is available to downstream nodes at `output.{node_id}`.\n- Docs clearly distinguish `output_retries` from `max_retries`.\n\n## Assumptions\n\n- `output_retries=2` is the default.\n- Custom schema validation targets the final JSON object in the response text.\n- `status.json` fallback remains routing-specific.\n- Provider-native response schema is used for prompt nodes only where it is safe.\n- ACP support can be added later after there is a guaranteed context-preserving repair mechanism.\n", "internal.retry_count.toolchain": 0, "thread.simplify_gpt.current_node": "verify", "thread.implement.current_node": "simplify_opus", "internal.retry_count.verify": 0, + "response.fixup": "All verify steps pass:\n- Merge with origin/main: clean\n- Format check: clean\n- Docs refresh: up-to-date\n- Banned auth patterns: none\n- Clippy: clean\n- Tests: 6273 passed, 181 skipped\n- Docs check: up-to-date\n- bun install / typecheck (web + api-client) / web tests: all pass\n- Release build (`-p fabro-cli`): success\n\nThe verify failure root cause was missing local git identity for the merge commit.
