# Feature Development — The Hands-Off Recipe This skill is the **operating manual** for building features the right way: every architectural choice captured before code was written, every phase reviewed by independent agents, every claim backed by reproducible evidence, every step reversible. By the end an external reviewer can audit the full trail and reach the same conclusion you did. --- ## When to use This skill handles **Medium and Deep** work. Classification happens inside the skill at Stage 0 — auto-classify, announce, proceed without asking. - **Light** — zero new logic, diff readable in 10 seconds: handle inline with TDD + self-review. Do NOT enter Stage 1. Exit the skill and handle it as the main agent. - **Medium** — fixes or improves existing behavior, no new product surface: abbreviated spec audit → fix plan → single-round review (architect + tester) → TDD execution with code-reviewer + phase-auditor → phase-auditor final check. - **Deep** — adds new capability or surface that didn't exist: full 7-stage recipe. ### Classification rule **Core question:** "Am I changing what already exists, or adding something new?" Changing/fixing → Medium. Adding new capability → Deep. | Path | When | Examples | |---|---|---| | **Light** | Zero new logic. Diff readable in 10 sec. | Typo, rename, comment, config value, reorder imports | | **Medium** | Fixes or improves existing behavior. No new product surface. | Bug fix (multi-file ok), refactor a module, add miss
