mattpocockSkill

code-review

mattpocock/skills/skills/engineering/code-review/SKILL.md

Review the changes since a fixed point (commit, branch, tag, or merge-base) along two axes: Standards (does the code follow this repo's documented coding standards?) and Spec (does the code match what the originating issue/spec asked for?). Runs both reviews in parallel sub-agents and reports them side by side. Use when the user wants to review a branch, a PR, work-in-progress changes, or asks to \"review since X\".

SupabaseReads credentialsSkill

review-the-docs

supabase/supabase/.agents/skills/review-the-docs/SKILL.md

Review Supabase docs changes locally in your `supabase/supabase` checkout — either an open PR (triage, classify, verify) or your own branch before opening a PR (local self-review). Covers markdown pipeline, MDX content, tutorials, examples, Studio links, and docs tooling. Use when asked to review docs PRs, self-review a draft branch, check who has approved, verify build output, or evaluate supabase/supabase documentation changes.

MicrosoftReads credentialsSkill

api-review

microsoft/playwright/.claude/skills/api-review/SKILL.md

Produce the "Playwright 1.xx API Review" artifact for a range of commits - the public API additions and the breaking or behavior changes that affect existing users since the last API review or since the last release, ordered by impact, each with links, before/after snippets and a documentation check. Covers microsoft/playwright (Node.js) and the Python, Java and .NET ports. Use when asked for an API review, to review API changes, or to check what changed in the public API since a release or since the last review.

addyosmaniSkill

spec-driven-development

addyosmani/agent-skills/skills/spec-driven-development/SKILL.md

Creates specs before coding. Use when starting a new project, feature, or significant change and no specification exists yet. Use when drafting a PRD or requirements document with objectives and scope, or when requirements are unclear, ambiguous, or only exist as a vague idea. Use when a single requirement spans several independently testable capabilities and needs decomposing into a capability map of modules before specifying. Use when evolving a shipped spec — scoping a V1, deferring ideas to a V2 backlog, or writing a follow-up spec for a change to an existing feature.

release-note-generation

microsoft/PowerToys/.github/skills/release-note-generation/SKILL.md

Toolkit for generating PowerToys stable or preview release notes from GitHub milestones, commit ranges, or Azure DevOps release-candidate builds. Prepare draft preview releases with three-component GitHub tags while preserving four-component build and asset versions. Use when asked to create release notes, summarize milestone PRs, generate changelog, prepare a draft preview release, calculate PR deltas across main and stable, update release documentation, manage PR milestones, or prepare and validate release assets.
