{"type":"custom_message","customType":"gsd-auto","content":"You are executing GSD auto-mode.\n\n## Working Directory\n\nYour working directory is `/home/aux/projects/content-to-kb-automator`. All file reads, writes, and shell commands MUST operate relative to this directory. Do NOT `cd` to any other directory.\n\nA researcher explored the codebase and a planner decomposed the work — you are the executor. The task plan below is your authoritative contract for the slice goal and verification bar, but it is not a substitute for local reality. Verify the referenced files and surrounding code before changing them. Do not do broad re-research or spontaneous re-planning. Small factual corrections, file-path fixes, and local implementation adaptations are part of execution. Escalate to `blocker_discovered: true` only when the slice contract or downstream task graph no longer holds.\n\n\n\n\n\n## Backing Source Artifacts\n- Slice plan: `/home/aux/projects/content-to-kb-automator/.gsd/milestones/M013/slices/S04/S04-PLAN.md`\n- Task plan source: `.gsd/milestones/M013/slices/S04/tasks/T01-PLAN.md`\n- Prior task summaries in this slice:\n- (no prior tasks)\n\nThen:\n0. Narrate step transitions, key implementation decisions, and verification outcomes as you work. Keep it terse — one line between tool-call clusters, not between every call — but write complete sentences in user-facing prose, not shorthand notes or scratchpad fragments.\n1.  Follow any activated skills before writing code. If no skills match this task, skip this step.\n2. Execute the steps in the inlined task plan, adapting minor local mismatches when the surrounding code differs from the planner's snapshot\n3. Build the real thing. If the task plan says \"create login endpoint\", build an endpoint that actually authenticates against a real store, not one that returns a hardcoded success response. If the task plan says \"create dashboard page\", build a page that renders real data from the API, not a component with hardcoded props. Stubs and mocks are for tests, not for the shipped feature.\n4. Write or update tests as part of execution — tests are verification, not an afterthought. If the slice plan defines test files in its Verification section and this is the first task, create them (they should initially fail).\n5. When implementing non-trivial runtime behavior (async flows, API boundaries, background processes, error paths), add or preserve agent-usable observability. Skip this for simple changes where it doesn't apply.\n\n   **Background process rule:** Never use bare `command &` to run background processes. The shell's `&` operator leaves stdout/stderr attached to the parent, which causes the Bash tool to hang indefinitely waiting for those streams to close. Always redirect output before backgrounding:\n   - Correct: `command > /dev/null 2>&1 &` or `nohup command > /dev/null 2>&1 &`\n   - Example: `python -m http.server 8080 > /dev/null 2>&1 &` (NOT `python -m http.server 8080 &`)\n   - Preferred: use the `bg_shell` tool if available — it manages process lifecycle correctly without stream-inheritance issues\n6. If the task plan includes a **Failure Modes** section (Q5), implement the error/timeout/malformed handling specified. Verify each dependency's failure path is handled. Skip if the section is absent.\n7. If the task plan includes a **Load Profile** section (Q6), implement protections for the identified 10x breakpoint (connection pooling, rate limiting, pagination, etc.). Skip if absent.\n8. If the task plan includes a **Negative Tests** section (Q7), write the specified negative test cases alongside the happy-path tests — malformed inputs, error paths, and boundary conditions. Skip if absent.\n9. Verify must-haves are met by running concrete checks (tests, commands, observable behaviors)\n10. Run the slice-level verification checks defined in the slice plan's Verification section. Track which pass. On the final task of the slice, all must pass before marking done. On intermediate tasks, partial passes are expected — note which ones pass in the summary.\n11. After the verification gate runs (you'll see gate results in stderr/notify output), populate the `## Verification Evidence` table in your task summary with the check results. Use the `formatEvidenceTable` format: one row per check with command, exit code, verdict (✅ pass / ❌ fail), and duration. If no verification commands were discovered, note that in the section.\n12. If the task touches UI, browser flows, DOM behavior, or user-visible web state:\n   - exercise the real flow in the browser\n   - prefer `browser_batch` when the next few actions are obvious and sequential\n   - prefer `browser_assert` for explicit pass/fail verification of the intended outcome\n   - use `browser_diff` when an action's effect is ambiguous\n   - use console/network/dialog diagnostics when validating async, stateful, or failure-prone UI\n   - record verification in terms of explicit checks passed/failed, not only prose interpretation\n13. If the task plan includes an Observability Impact section, verify those signals directly. Skip this step if the task plan omits the section.\n14. **If execution is running long or verification fails:**\n\n    **Context budget:** You have approximately **~80K chars** reserved for verification context. If you've used most of your context and haven't finished all steps, stop implementing and prioritize writing the task summary with clear notes on what's done and what remains. A partial summary that enables clean resumption is more valuable than one more half-finished step with no documentation. Never sacrifice summary quality for one more implementation step.\n\n    **Debugging discipline:** If a verification check fails or implementation hits unexpected behavior:\n    - Form a hypothesis first. State what you think is wrong and why, then test that specific theory. Don't shotgun-fix.\n    - Change one variable at a time. Make one change, test, observe. Multiple simultaneous changes mean you can't attribute what worked.\n    - Read completely. When investigating, read entire functions and their imports, not just the line that looks relevant.\n    - Distinguish \"I know\" from \"I assume.\" Observable facts (the error says X) are strong evidence. Assumptions (this library should work this way) need verification.\n    - Know when to stop. If you've tried 3+ fixes without progress, your mental model is probably wrong. Stop. List what you know for certain. List what you've ruled out. Form fresh hypotheses from there.\n    - Don't fix symptoms. Understand *why* something fails before changing code. A test that passes after a change you don't understand is luck, not a fix.\n15. **Blocker discovery:** If execution reveals that the remaining slice plan is fundamentally invalid — not just a bug or minor deviation, but a plan-invalidating finding like a wrong API, missing capability, or architectural mismatch — set `blocker_discovered: true` in the task summary frontmatter and describe the blocker clearly in the summary narrative. Do NOT set `blocker_discovered: true` for ordinary debugging, minor deviations, or issues that can be fixed within the current task or the remaining plan. This flag triggers an automatic replan of the slice.\n16. If you made an architectural, pattern, library, or observability decision during this task that downstream work should know about, append it to `.gsd/DECISIONS.md` (read the template at `~/.gsd/agent/extensions/gsd/templates/decisions.md` if the file doesn't exist yet). Not every task produces decisions — only append when a meaningful choice was made.\n17. If you discover a non-obvious rule, recurring gotcha, or useful pattern during execution, append it to `.gsd/KNOWLEDGE.md`. Only add entries that would save future agents from repeating your investigation. Don't add obvious things.\n18. Read the template at `~/.gsd/agent/extensions/gsd/templates/task-summary.md`\n19. Write `/home/aux/projects/content-to-kb-automator/.gsd/milestones/M013/slices/S04/tasks/T01-SUMMARY.md`\n20. Call `gsd_complete_task` with milestone_id, slice_id, task_id, and a summary of what was accomplished. This is your final required step — do NOT manually edit PLAN.md checkboxes. The tool marks the task complete, updates the DB, and renders PLAN.md automatically.\n21. Do not run git commands — the system reads your task summary after completion and creates a meaningful commit from it (type inferred from title, message from your one-liner, key files from frontmatter). Write a clear, specific one-liner in the summary — it becomes the commit message.\n\nAll work stays in your working directory: `/home/aux/projects/content-to-kb-automator`.\n\n**You MUST call `gsd_complete_task` AND write `/home/aux/projects/content-to-kb-automator/.gsd/milestones/M013/slices/S04/tasks/T01-SUMMARY.md` before finishing.**\n\nWhen done, say: \"Task T01 complete.\"\n## Slice Plan Excerpt\nSource: `.gsd/milestones/M013/slices/S04/S04-PLAN.md`\n**Goal:** Extend the prompt optimization loop from stage-5-only to stages 2-4, with stage-appropriate scoring rubrics, fixture formats, and variant validation — so `optimize --stage N` works for any pipeline stage.\n**Demo:** After this: Run `python -m pipeline.quality optimize --stage 3 --iterations 5` — optimizes extraction prompts with stage-appropriate scoring\n\n## UNIT: Execute Task T01 (\"Generalize scorer with stage config registry and update variant generator\") — Slice S04 (\"Expand to Pipeline Stages 2-4\"), Milestone M013\n\n## Resume State\n- No continue file present.

Generalize ScoreResult to use a `scores: dict[str, float]` field instead of 5 named fields (keep backward compat via properties). Add a `score_stage_output()` method to ScoreRunner that accepts arbitrary stage output + input and scores using the stage's rubric. Update variant_generator.py to accept format markers as a parameter rather than using the hardcoded `_FORMAT_MARKERS` list, and generalize the meta-prompt to work for any stage (not just synthesis).\n\n## Context\n\nThe existing scorer has a hardcoded `SCORING_RUBRIC` with 5 stage-5 dimensions (structural, content_specificity, voice_preservation, readability, factual_fidelity). `ScoreResult` has these as named float fields.

Each stage has a full LLM-as-judge rubric tailored to its output type (segmentation quality for stage 2, extraction quality for stage 3, classification quality for stage 4, synthesis quality for stage 5).\n\nReplaced `ScoreResult`'s five named float fields with a generic `scores: dict[str, float]`. Added `@property` accessors for `structural`, `content_specificity`, `voice_preservation`, `readability`, and `factual_fidelity` that delegate to the dict — preserving backward compatibility for all existing callers (optimizer.py, `__main__.py`'s `getattr` pattern).\n\nAdded `score_stage_output(stage, output_json, input_json)` to `ScoreRunner` — selects the stage config, builds a generic user prompt, calls the LLM judge with the stage's rubric, and parses scores using the stage's dimension list. `score_page()` now delegates to `score_stage_output(stage=5, ...)`.\n\nGeneralized `variant_generator.py`: `VARIANT_META_PROMPT` is now a template with a `{dimension_descriptions}` placeholder. `generate()` accepts `format_markers` and `stage` keyword arguments. It resolves dimensions and markers from `STAGE_CONFIGS[stage]` when not explicitly provided. The `_build_user_prompt` helper now accepts a `dimensions` parameter and reads scores from `scores.scores` dict instead of `getattr`.\n\n## Verification\n\n```\ncd backend && python -c \"from pipeline.quality.scorer import STAGE_CONFIGS, ScoreResult, ScoreRunner, DIMENSIONS; assert 2 in STAGE_CONFIGS and 3 in STAGE_CONFIGS and 4 in STAGE_CONFIGS and 5 in STAGE_CONFIGS; r = ScoreResult(scores={'structural': 0.8, 'readability': 0.7}, composite=0.75); print('scorer ok')\"\n# → scorer ok\n\ncd backend && python -c \"from pipeline.quality.variant_generator import PromptVariantGenerator; print('generator ok')\"\n# → generator ok\n```\n\nAlso verified: `StageConfig.get_schema()` returns correct Pydantic classes for all 4 stages, backward-compat `getattr(result, dim)` pattern works for stage 5 dimensions.\n\n## Verification Evidence\n\n| # | Command | Exit Code | Verdict | Duration |\n|---|---------|-----------|---------|----------|\n| 1 | `python -c \"from pipeline.quality.scorer import STAGE_CONFIGS, ScoreResult, ScoreRunner, DIMENSIONS; assert 2 in STAGE_CONFIGS and 3 in STAGE_CONFIGS and 4 in STAGE_CONFIGS and 5 in STAGE_CONFIGS; r = ScoreResult(scores={'structural': 0.8, 'readability': 0.7}, composite=0.75); print('scorer ok')\"` | 0 | ✅ pass | 1s |\n| 2 | `python -c \"from pipeline.quality.variant_generator import PromptVariantGenerator; print('generator ok')\"` | 0 | ✅ pass | 1s |\n| 3 | `python -c \"from pipeline.quality.scorer import STAGE_CONFIGS, ScoreResult, DIMENSIONS; [cfg.get_schema() for cfg in STAGE_CONFIGS.values()]; r = ScoreResult(scores={'structural': 0.8}, composite=0.8); assert r.structural == 0.8; print('compat ok')\"` | 0 | ✅ pass | 1s |\n\n## Diagnostics\n\nNone — this is a data structure and method generalization. Errors surface via ScoreResult.error field and logger.warning for missing/invalid dimensions.\n\n## Deviations\n\n- Added `SCORING_RUBRIC` as a backward-compat alias for `_STAGE_5_RUBRIC` since `synthesize_and_score()` and the stage 5 config both reference it.\n- Made `VARIANT_META_PROMPT` a template string with `{dimension_descriptions}` rather than a static string — cleaner than building dimension text procedurally.\n\n## Known Issues\n\n- `__main__.py` line 148 uses `getattr(result.best_score, d) for d in DIMENSIONS` which only works for stage 5. Will need updating when the optimize CLI is generalized for other stages (expected in a later task in this slice).\n\n## Files Created/Modified\n\n- `backend/pipeline/quality/scorer.py` — Added StageConfig class, STAGE_CONFIGS registry (stages 2-5), per-stage rubric strings, generalized ScoreResult to use scores dict with backward-compat properties, added score_stage_output() method\n- `backend/pipeline/quality/variant_generator.py` — Templatized VARIANT_META_PROMPT with per-stage dimension descriptions, added format_markers/stage params to generate(), updated _build_user_prompt to use scores dict\n","path":"/home/aux/projects/content-to-kb-automator/.gsd/milestones/M013/slices/S04/tasks/T01-SUMMARY.md"}}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":1,"output":1683,"cacheRead":86458,"cacheWrite":599,"totalTokens":88741,"cost":{"input":0.000005,"output":0.042075,"cacheRead":0.043229,"cacheWrite":0.00374375,"total":0.08905275}},"stopReason":"toolUse","timestamp":1775035179259}}
