-1. **Read `.loop/progress.md`** — check the **Codebase Patterns** section first (top of file), then skim recent session log entries for context
-2. **Read `.loop/prd.json`** — find the highest-priority story where `passes: false`
-3. **Read the sprint contract** for that story at `.loop/contracts/{story-id}.contract.md` (if it exists)
-4. **Check the story's `notes` field** — if it contains `[REJECTED]` entries, those are feedback from a previous evaluator. Address the specific issues raised.
-5. **Confirm the git branch** — the loop has already checked you out on the correct branch per `prd.json.branchName`. Run `git branch --show-current` to verify if needed.

-## Work Rules
+## Rules
 
 - **ONE story per iteration.** Do not attempt multiple stories.
-- **Read before writing.** Understand existing code before modifying it. Search for existing implementations before creating new ones.
-- **Follow existing patterns.** Check Codebase Patterns in progress.md. Match the project's style, naming, and structure.
-- **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.
-- **Commit after completing the story.** Message format: `feat: [Story ID] - [Story Title]`
+- **Read before writing.** Understand existing code before modifying.
+- **No placeholders.** Every implementation must be complete and functional.
+- **Run quality gates** before committing (typecheck, tests, lint — whatever the project uses).
+- **Commit** with message: `feat: [Story ID] - [Story Title]`
 
-## Quality Gates
+## After Completing
 
-Before marking a story as complete:
-- Run the project's type checker (if applicable)
-- Run the project's test suite (if applicable)
-- 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)
+1. Update `.loop/prd.json` — set `passes: true` for the story
+2. Append a summary to `.loop/progress.md` — what was done, files changed, learnings
+3. Update Codebase Patterns in progress.md if you discovered a reusable pattern
 
 ## Completion Signal
 
-- If ALL stories in prd.json have `passes: true`, respond with: `<promise>COMPLETE</promise>`
-- Otherwise, end your response normally. The next iteration will pick up the next story.

-- Maximum lines to write: {{MAX_LINES_TO_WRITE}}
-- Maximum files to modify: {{MAX_FILES_TO_MODIFY}}
-- If you approach a limit, stop and note what remains in progress.md.
