## Your Target ## Your Target
Evaluate story **`{{CURRENT_STORY_ID}}`**. This is the story the generator just worked on. Evaluate story **`{{CURRENT_STORY_ID}}`**.
## Evaluation Process ## Evaluation Process
1. **Read `.loop/prd.json`** — find story `{{CURRENT_STORY_ID}}` and its acceptance criteria 1. Read `.loop/prd.json` — find the story and its acceptance criteria
2. **Read the sprint contract** at `.loop/contracts/{{CURRENT_STORY_ID}}.contract.md` (if it exists) 2. Read the sprint contract at `.loop/contracts/{{CURRENT_STORY_ID}}.contract.md` (if it exists)
3. **Read `.loop/progress.md`** — check the latest session log entry for what the generator claims to have done 3. Read `.loop/progress.md` — check what the generator claims to have done
4. **Examine the actual changes:** 4. Run `git diff {{PRE_GENERATOR_SHA}}..HEAD` to see actual changes
- Run `git diff {{PRE_GENERATOR_SHA}}..HEAD` to see ALL changes the generator made 5. Read modified files IN FULL (not just the diff)
- Read the modified files IN FULL (not just the diff) to understand context 6. For EACH acceptance criterion — does the code ACTUALLY satisfy it? Not "looks like it might" — ACTUALLY.
5. **For EACH acceptance criterion in prd.json**, independently verify: 7. Run quality checks yourself (typecheck, tests, lint)
- Does the code ACTUALLY satisfy this criterion? 8. **Actually run the code.** Use whatever tools are available. Code that looks correct but doesn't run is not complete.
- Not "does it look like it might" — does it ACTUALLY?
6. **Run quality checks yourself:**
- Typecheck (if applicable)
- Tests (if applicable)
- Lint (if applicable)
7. **Check for regressions:**
- Did the changes break anything that was working before?
- Did the generator modify files outside the story's scope?
8. **Check for anti-patterns:**
- Placeholder or stub implementations disguised as complete
- Hardcoded values that should be configurable
- Missing error handling at system boundaries
- Security issues (hardcoded secrets, unsanitized input, SQL injection)
## Verdict Format ## Verdict
You MUST do TWO things when delivering your verdict: Write your verdict to `{{LOOP_DIR}}/.verdict` AND include it in your response.
### 1. Write the verdict to a file **PASS:** `<verdict>PASS</verdict>`
Write your verdict to `{{LOOP_DIR}}/.verdict` using the Write tool. This file is how the loop harness reads your decision. **REJECT:**
**If PASS:**
```
<verdict>PASS</verdict>
```
**If REJECT:**
``` ```
<verdict>REJECT</verdict> <verdict>REJECT</verdict>
<rejection_reason> <rejection_reason>Specific, actionable description with file paths and line numbers.</rejection_reason>
[Specific, actionable description of what failed and why.
Include file paths and line numbers.
Be concrete — "the function doesn't handle null input" not "there might be edge cases".]
</rejection_reason>
``` ```
### 2. Also include the verdict in your response ## Reject If
End your response with the same verdict block so it's visible in the terminal output. - Any acceptance criterion not met
- Tests, typecheck, or lint fail
- Runtime errors (page doesn't load, build fails, crashes)
- Placeholder/stub code
- Regressions in existing functionality
## Runtime Verification ## Scope
Do not just read the code — **actually run it.** Use whatever tools are available to you (bash, MCP tools, etc.) to verify the project builds, runs, and behaves correctly. Code that looks correct but doesn't run is not complete. Read ≤ {{MAX_FILES_TO_READ}} files · Focus on what the generator changed
**Runtime errors = automatic REJECT.**
## What Warrants Rejection
- ANY acceptance criterion not actually met (not "mostly met" — MET)
- Tests fail
- Typecheck fails
- Runtime errors (page doesn't load, console errors, server crashes)
- Placeholder/stub code left in place
- Security vulnerability introduced
- Regression in existing functionality
- Contract's Done Conditions not satisfied (if contract exists)
## What Does NOT Warrant Rejection
- Code style preferences (as long as it matches project conventions)
- Minor naming choices
- Missing optimization that wasn't in the criteria
- Absence of features not in the story scope
## Scope Budget
- Maximum files to read: {{MAX_FILES_TO_READ}}
- Focus your verification on the files the generator changed
- You do NOT need to read the entire codebase

- **Read before writing.** Understand existing code before modifying it. Search for existing implementations before creating new ones. - **Read before writing.** Understand existing code before modifying.

- **No placeholders.** Every implementation must be complete and functional. If a story is too large, stop and note what remains — do NOT leave stub/placeholder code. - **Run quality gates** before committing (typecheck, tests, lint — whatever the project uses).
- **Commit after completing the story.** Message format: `feat: [Story ID] - [Story Title]` - **Commit** with message: `feat: [Story ID] - [Story Title]`
## Quality Gates ## After Completing
Before marking a story as complete: 1. Update `.loop/prd.json` — set `passes: true` for the story
- Run the project's type checker (if applicable) 2. Append a summary to `.loop/progress.md` — what was done, files changed, learnings
- Run the project's test suite (if applicable) 3. Update Codebase Patterns in progress.md if you discovered a reusable pattern
- Run the project's linter (if applicable)
- All must pass. If they fail, fix the issues before committing.
## After Completing the Story
1. **Update `.loop/prd.json`** — set `passes: true` for the completed story (the harness also sets this on evaluator PASS as a safety net, but you should still do it)
2. **Append to `.loop/progress.md`** with this format:
```
### [Story ID] — [Story Title]
Date: YYYY-MM-DD HH:MM
**What was done:**
- Bullet points of changes made
**Files changed:**
- path/to/file.ext — brief description
**Learnings for future iterations:**
- Patterns discovered, gotchas encountered, useful context
---
```
3. **Update Codebase Patterns** (top of progress.md) if you discovered a reusable pattern
4. **Update AGENTS.md/CLAUDE.md** in modified directories if you discovered genuinely reusable knowledge (API conventions, non-obvious requirements, testing approaches)
## Completion Signal ## Completion Signal
- If ALL stories in prd.json have `passes: true`, respond with: `<promise>COMPLETE</promise>` If ALL stories have `passes: true`, respond with: `<promise>COMPLETE</promise>`
- Otherwise, end your response normally. The next iteration will pick up the next story.
