impl

# Impl Use this Codex skill for phase-shaped implementation from `specs/91-impl-plan.md`. The canonical workflow is the Claude impl skill at `.claude/skills/impl/SKILL.md`; follow it, with the Codex-specific adjustments below. ## Codex Adjustments - Read `AGENTS.md`, `CLAUDE.md`, `specs/91-impl-plan.md`, cited specs, and relevant `docs/research/` memos before editing. - Use Codex's normal task tracking and local review. Use subagents only when the user explicitly asks for delegated or parallel agent work. - Preserve user changes. Check `git status --short` before edits and avoid broad staging commands. - Keep implementation scoped to the requested phase. Defer out-of-phase findings to `specs/93-improvements-review.md`. ## Workflow 1. Bind the exact phase or milestone from `specs/91-impl-plan.md`. 2. Read every cited spec section and relevant research memo. 3. Identify exit criteria before writing code. 4. Implement tasks in dependency order. 5. Run local tests after meaningful changes and all standard gates before done. 6. Review the diff against the specs and `CLAUDE.md`; fix valid in-phase findings. 7. Report changed files, quality gates, residual risk, and the next unlocked phase. ## Required Gates ```bash cargo build --workspace --all-targets cargo test --workspace --all-targets cargo +nightly fmt -- --check cargo clippy --workspace --all-targets -- -D warnings RUSTDOCFLAGS="-D warnings" cargo doc --workspace --no-deps ``` For boundary modules and external-input paths, also run the stricter Clippy command from `AGENTS.md`. Run `cargo deny check` and `cargo audit` if dependencies change. ## Quality Bar No TODOs, placeholders, dead-code suppressions, `unsafe`, `unwrap`, or `expect` in production paths. Public surfaces need docs and tests. Spec adherence is binary: if implementation and spec disagree, stop and reconcile the mismatch in writing before continuing.
