Reads the diff between the current branch and main and produces a production pre-flight checklist of everything that must be done or configured once the change merges. Use before merging or deploying a branch.

Suggest tests worth writing for a feature using the ZOMBIES heuristic (Zero, One, Many, Boundaries, Interface, Exceptions, Simple scenarios). Pass a free-text feature description, or omit args to use the current branch's diff. Outputs only the categories that apply — not a full ZOMBIES checklist.

🌡️ Evaluate every dependency a branch pulls in — client or server, any language — against the WARM check (Worth it, Alive, Right-sized, Maintained securely). Diffs the branch against a base, finds newly added or upgraded direct dependencies across all manifests, and scores each one. Use when the user asks to "WARM check" a branch, vet new dependencies, or review what a PR adds to the dependency tree.

Triage a branch or diff by grouping changed files into feature areas, assigning each a risk tier (High/Medium/Low), and producing a scannable summary that helps decide where to spend review time. Use when the user asks to "triage" a branch, PR, or diff.

Scan a branch or diff against the First Five checklist (Error Handling, Input Boundaries, External Calls, State Mutations, Assumed Dependencies) and report only genuine concerns. Use when the user asks to "run the first five" on a branch or diff.

Prepare a structured, scannable review checklist for a branch or diff, grouped by feature change and applying the four-pass review order (Types, Data Flow, Business Logic, Edge Cases) within each feature. Use when the user asks to "prep a review", "review order", or wants a checklist to manually walk through changes.

Convert the current plan, code review, or structured content in context into a persistent markdown checklist file under .claude/plans/

Code review staged changes or a specific area of the codebase, optionally delegating to a chosen agent. Use when the user wants a code review.

Generate a detailed features.md document from a spec.md, or sync changes between spec.md and features.md when either file is updated. Use this skill whenever the user wants to expand a product spec into a full feature list, asks to "generate features", "create features.md", "expand the spec", "update features from spec", or "sync spec and features". Also trigger when the user has modified either spec.md or features.md and wants to keep them in sync. Always use this skill when both files are in play together.

Generate a detailed product specification document from a vague idea, rough description, or supporting materials (UI sketches, screenshots, notes, existing docs). Use this skill whenever the user wants to turn a rough concept into a structured spec — even if they say things like "write up a spec for...", "turn this idea into a requirements doc", "I have this rough idea for a product", "help me spec this out", "create a PRD for...", or uploads images/files and wants a spec written from them. Covers all product types including internal tools. Trigger this skill even if the request seems simple — a vague one-liner idea deserves a proper spec just as much as a detailed brief.
