    Wiring Audit · nickcrew bundle

    User-triggered audit that finds wiring drift between a project's UI surfaces and backend capabilities — orphan surfaces (UI calls endpoints/hooks/procedures that no longer exist), unwired capabilities (backend routes/exports that nothing surfaces), shape drift (both exist but contracts mismatch), method drift (URL matches, HTTP verb does not), validation drift (frontend vs backend rules diverged), permission drift (UI exposes what backend forbids or vice versa), stale labels (UI text references renamed backend concepts), and unsurfaced configuration (env vars or flags that gate behavior with no UI or CLI to control them). This skill should be used when the user asks to "audit our wiring," "find UI/backend drift," "find unwired capabilities," "find stale surfaces," "check for contract violations," "find unused endpoints," "find unused hooks," "what mismatches between UI and backend," or any similar request whose deliverable is a prioritized findings report rather than a descriptive snapshot.

Auto-engages on prose writing tasks; checks banned punctuation, stock vocabulary, and mechanical patterns. For the structural judgment pass on rhythm and rhetorical reflexes, use ai-tells-review. Not a replacement for voice skills like nick-voice; this removes machine fingerprints, it does not add a target voice.

    Mapping Suite · nickcrew bundle

    User-triggered orchestrator that walks the user through running multiple sibling mapping/audit/doc skills against a shared scope, then assembles their outputs into one navigable artifact. Coaches rather than auto-runs — at each step the orchestrator presents the next sibling skill, recommended scope inheritance, and approval gate; the user invokes the sibling and confirms before moving on. Resolves the prior arch-analysis lookup once at suite start so every sibling skill inherits the same scope. Records each run's output path in a suite manifest. Produces a combined navigation HTML that links to each sibling's standalone HTML for one-stop sharing. Ships two named recipes — "release-driver onboarding" (for tooling that drives releases) and "deployed-system onboarding" (for systems that get deployed) — and supports custom plans. Trigger on "run our mapping suite," "do a complete onboarding," "build the combined report," "I need to onboard to system X," "give me the full picture of this codebase," or when the us

    Atomic Commits · nickcrew

    Use this skill when a working tree contains uncommitted changes that need to be split into a sequence of atomic commits — typically after a long session, an agent hand-off, a rebase resolution, or anytime `git status` shows mixed work that was not committed as it landed. The skill assumes the agent has fresh context and did not author most of the diff, so it treats the working tree as evidence to investigate before grouping. Optimizes for `git bisect`: each commit is the smallest buildable and deployable unit, and no smaller. Uses `cortex git commit` for file-level commits and `cortex git patch --diff` when unrelated changes share a file.
