Do not change release workflows, secrets, protected files, or security settings without a high-risk issue and human/admin approval. +9. Do not infer the contents of web references. Read each required reference and each pertinent sublink before summarizing or using it. +10. If a required reference or tool is unavailable, record the blocker and continue only with work that does not depend on the missing fact. + +## 1. Phase model + +Each phase must be a separate issue and pull request unless the repository owner explicitly combines phases. Earlier phases must be green before later phases become blocking. + +### Phase 0: Bootstrap the harness + +Goal: add the repo-local harness and CI structure without changing product behavior. + +Allowed changes: + +- Repository intake documentation. +- Reference manifest and notes. +- `AGENTS.md`, `CLAUDE.md`, harness docs, testing docs, and quality score. +- Issue and pull request templates. +- CI workflow with an aggregate `ci-required` job. +- Validation scripts for harness files and references. +- Local command wrappers such as `Makefile` and `noxfile.py`. +- Tool configuration for existing tools or new development-only tools. +- Claude Code project skills, subagents, hooks, and workflows if syntax can be validated against the installed Claude Code version. +- Placeholder/stub docs where repository-specific facts still need owner confirmation. + +Disallowed changes: + +- Product source behavior changes. +- Public API changes. +- Default branch rename. +- Release publishing changes that could publish artifacts. +- Coverage thresholds that immediately fail on known legacy gaps unless the repo already satisfies them. +- Required security jobs that are known to fail on existing code without a staged remediation plan. + +Phase 0 acceptance criteria: + +- The current test suite still passes, or existing failures are documented as pre-existing with exact reproduction commands. +- `make harness-check` passes. +- The CI workflow has no required path filters and exposes an aggregate `ci-required` job. +- A manual GitHub configuration checklist exists. +- `QUALITY_SCORE.md` is initialized from discovered facts. +- The pull request clearly states that no product behavior changed. + +### Phase 1: Configure GitHub protections + +Goal: make GitHub reject unsafe merges to the discovered default branch. + +This phase usually needs a human/admin because repository settings, branch protection, rulesets, environments, secrets, and security features may not be writable by the coding agent. + +Acceptance criteria: + +- Direct pushes to the default branch are blocked. +- Pull requests are required before merge. +- `ci-required` is a required status check. +- Required conversations must be resolved. +- CODEOWNER review is required for harness, CI, release, security, and packaging files. +- Force pushes and branch deletion are blocked. +- Admin bypass is disabled after an emergency access path is confirmed. + +### Phase 2: Enforce clean-context agent workflow + +Goal: require evidence that code changes were developed through independent test-author, implementer, and reviewer roles. + +Acceptance criteria: + +- PRs with source changes fail validation when linked issue, red-test proof, implementation metadata, or review metadata is missing. +- Red tests must be shown to fail on the base commit for the intended reason. +- Implementation must not modify red tests except through the documented test-amendment protocol. +- Numerical/scientific changes require numerics review metadata. + +### Phase 3: Ratchet test coverage and test quality + +Goal: move from baseline coverage to practical complete coverage. + +Acceptance criteria: + +- Coverage baseline is recorded. +- Total coverage cannot decrease without a linked waiver issue. +- Diff coverage is required for changed Python code after the repo can support it. +- Public APIs have behavior assertions, not only import or smoke tests. +- Numerical tolerances and fixtures follow repo policy. + +### Phase 4: Harden downstream and release flows + +Goal: protect users, dependent repositories, and package publishing. + +Acceptance criteria: + +- If the repo has downstream consumers, it can run downstream smoke tests against a local build. +- Package build and installed-artifact smoke tests are required. +- Release workflows require protected environments and human approval. +- Release tokens are not exposed to ordinary pull request workflows. + +## 2. Repository intake + +Run repository intake before making Phase 0 changes. Write the result to: + +```text +docs/generated/repo-intake.md +``` + +The intake must identify facts, assumptions, and open questions separately. + +### 2.1 Required facts to discover + +Record: + +- Repository name and remote URL. +- Default branch. +- Current branch and base commit SHA. +- Primary language and secondary languages. +- Package/import name or names. +- Public package/module layout. +- Existing test directories and test runner. +- Existing CI workflows and triggers. +- Existing release workflows and publishing targets. +- Existing package metadata and supported runtime versions. +- Existing dependency files. +- Development dependency mechanism, if any. +- Existing linters, formatters, type checkers, and docs tools. +- Current coverage tooling and coverage baseline, if available. +- Existing fixtures, generated files, and binary data. +- Hardware-facing, scientific, numerical, image-processing, or device-control areas. +- Downstream projects or consumers, if documented in the repo. +- Files that should require human/admin review. + +### 2.2 Required intake commands + +Use commands appropriate to the repo. The following are examples, not assumptions: + +```bash +git remote -v +git branch --show-current +git rev-parse HEAD +git symbolic-ref refs/remotes/origin/HEAD || true +find . -maxdepth 3 -type f | sort | sed 's#^./##' | head -300 +find .github -maxdepth 3 -type f -print 2>/dev/null | sort +find . -maxdepth 3 \( -name 'pyproject.toml' -o -name 'setup.py' -o -name 'setup.cfg' -o -name 'requirements*.txt' -o -name 'tox.ini' -o -name 'noxfile.py' \) -print +find . -maxdepth 3 \( -name 'test*.py' -o -name '*_test.py' \) -print | sort +``` + +If Python packaging exists, inspect metadata using the safest available route: + +```bash +python - <<'PY' +from pathlib import Path +for name in ['pyproject.toml', 'setup.py', 'setup.cfg']: + path = Path(name) + if path.exists(): + print(f'--- {name} ---') + print(path.read_text(errors='replace')[:6000]) +PY +``` + +Do not run release, publish, deployment, hardware-control, or destructive commands during intake. + +### 2.3 Intake output template + +```markdown +# Repository intake + +Date: +Base commit: +Default branch: +Current branch: + +## Facts + +## Assumptions + +## Open questions + +## Package and public API map + +## Existing tests + +## Existing CI and release workflows + +## Dependency and runtime support + +## Hardware/scientific/numerical areas + +## Fixtures and generated data + +## Downstream or integration surface + +## Files requiring human/admin review + +## Phase 0 implementation notes +``` + +## 3.

Mark unknowns as unknown and create follow-up issues. + +## 19. Downstream compatibility + +If intake finds downstream consumers, add a downstream policy. If no downstream consumers are known, create a placeholder stating that none were discovered. + +For a library repo, downstream smoke should: + +1. Build a local package artifact. +2. Create an isolated environment. +3. Install the downstream project with the local artifact. +4. Run a minimal smoke subset. +5. Record logs and versions. + +If a change breaks downstream behavior, choose one: + +1. Fix compatibility in the current repo. +2. Open coordinated downstream PRs. +3.
