+    instructions: |
+      Principles:
+      - Extract all requirements before coding. Missing one means failure.
+      - Understand before changing. Research the code first.
+      - Follow existing patterns and AGENTS.md if it exists.
+      - Stop when requirements are met. Nothing more.
+      - Verify through deterministic means.
+      - Your context degrades. The TODO is your memory. Update it after each step.
+
+    prompt: |
+      Solve GitHub issue #${ISSUE_NUMBER}: ${ISSUE_TITLE}
+
+      The issue is saved at /tmp/issue.json
+
+      Trigger comment:
+      ${TRIGGER_COMMENT}
+
+      Write this to your TODO immediately and update as you progress:
+
+      ## Phase 1: Understand
+      - [ ] Read /tmp/issue.json
+      - [ ] Write all requirements (explicit + implicit) to /tmp/requirements.md
+      - [ ] Read AGENTS.md if it exists
+
+      ## Phase 2: Research
+      - [ ] Explore codebase with analyze and rg
+      - [ ] Identify files that need to change
+      - [ ] Update TODO with findings
+
+      ## Phase 3: Plan
+      - [ ] Decide on implementation approach
+      - [ ] For nontrivial issues, use subagents to evaluate architecture or implementation choices
+      - [ ] Update TODO with specific changes to make
+
+      ## Phase 4: Implement
+      - [ ] Implement minimal fix per /tmp/requirements.md
+      - [ ] Before adding anything, check: is it in the requirements? If not, don't.
+      - [ ] No .github/, no lock files, no secrets
+
+      ## Phase 5: Verify
+      - [ ] source bin/activate-hermit
+      - [ ] cargo check
+      - [ ] cargo test (affected crates)
+      - [ ] cargo fmt
+      - [ ] ./scripts/clippy-lint.sh
+      - [ ] Fix failures, retry up to 3 times
+
+      ## Phase 6: Confirm (MANDATORY)
+      - [ ] Reread /tmp/issue.json
+      - [ ] Reread /tmp/requirements.md
+      - [ ] Confirm all requirements met, nothing extra added
+      - [ ] Write a summary of changes to /tmp/issue_summary.txt
+
+      The Phase 6 "Reread" steps MUST appear in your updated TODO. Skipping them is failure.
+
+      Only write /tmp/issue_summary.txt if the fix is complete and verified.
+      Run `git add` for any new files required for the fix.
+      Do NOT commit. Leave changes in the working directory for the workflow to handle.
