Audit an implemented /spec-format spec against the codebase. Walk every tagged constraint, ground each one in file:line evidence, execute the acceptance commands, and emit a single audit document. The spec itself is never modified — the audit doc is the only artifact this skill writes.
Validate Spec is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/validate-spec/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use whenever the user asks to "validate a spec", "audit a spec", "check if spec is implemented", "verify the spec is done", "is this spec really done", or otherwise wants closure on spec-driven work. Read-only against the spec — produces an audit, never modifies the spec itself.
The Validate Spec Claude Code skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 69,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
