Feature Build

Feature Build

Write code that fits the decisions already made — not framework-default scaffolding. This skill is thin on purpose: it keeps the build faithful to STACK.md and hands the real language work to specialists.

Before writing code

1. Read STACK.md, CLAUDE.md, and TASTE.md. If STACK.md is missing, run the tech-charter skill first — nothing is built on an undecided stack. (Check for and open these with your Read/Glob tools, not shell commands — OS portability.)
2. Stay inside the declared stack. A dependency not in STACK.md is not yours to add — if the feature genuinely needs one, go back and amend STACK.md as a decision, don't slip it in.
3. Name the smallest change that delivers the feature. YAGNI: no speculative abstraction, no layer a requirement hasn't forced.

Build

• Tests first. If tdd-guide is available, hand off to it. Otherwise write the failing test, make it pass, refactor — same loop, done inline.
• Match the surrounding code — its naming, its idioms, its error-handling. New code should be unattributable as "the AI part."
• Errors handled explicitly, at every boundary. No silent swallow.
• The one decision. Even in code, the fit to this project should be visible — a chosen boundary, a deliberate data shape — not a generated template.

Delegate the language review (portable)

Hand off to the most specific reviewer that exists in the install; skip silently if none do:

• Python → python-reviewer · TypeScript/JS → typescript-reviewer · Go → go-reviewer · Rust → rust-reviewer · React → react-reviewer (and the same pattern for other languages).
• No language-specific reviewer? Use code-reviewer if present, else review inline against CLAUDE.md.
• Build broken? build-error-resolver if present, else fix inline.

These are optional accelerators, not requirements — the skill works without any of them.

Before calling it done

Hand to the dev-critic agent (always shipped with this plugin) against STACK.md + TASTE.md. If it finds an undeclared dependency or code no human clearly decided, redo it.
