feature-spec skillA

feature-spec is agent-read markdown (skill) from hahaknight/claude-skills-pro: MUST USE before implementing any non-trivial feature (new endpoint, new module, new user-facing behavior) or when the user describes a feature vaguely — 先出方案/需求不清/design first. Converts vague asks into a 1-page spec with scope, contracts, edge cases, and test scenarios — getting alignment BEFORE code is written. Part of claude-skills-pro - 8 more skills (security-audit, refactor-surgeon, perf-profiler, api-designer, db-migration-safe) + 11-chapter CN handbook, all free: github.com/Hahaknight/cla.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add hahaknight/claude-skills-pro/feature-spec@git:20260911.d1f3748
Exact content
mdr add hahaknight/claude-skills-pro/feature-spec@sha256:bb91e44616af4674

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
