abel3005 Bundle Contradiction Audit사내 규정·지침·계약서 등 문서 묶음에서 서로 충돌하는 조항을 찾아내고, 어느 쪽이 우선하는지와 수정 문안까지 담은 점검 리포트를 만든다. 취업규칙·사규·운영지침·매뉴얼·계약서·정책 문서를 다루면서 "개정하면 어디를 같이 고쳐야 하는지", "규정끼리 안 맞는 것 같다", "예전 지침이 아직 살아 있는지", "문서 간 정합성/일관성 점검", "규정 충돌", "개정 영향 분석", "폐기 누락" 같은 말이 나오면 반드시 이 스킬을 사용한다. 사용자가 '충돌 점검'이라는 단어를 쓰지 않아도, 여러 문서를 놓고 서로 안 맞는 부분을 찾아 달라거나 한 문서를 고쳤을 때의 파급을 묻는 상황이면 사용한다. 문서 요약, 단일 문서 교정, 번역에는 사용하지 않는다.

google Bundle Github Pr ReviewReview a GitHub pull request and leave inline comments in a natural human reviewing voice, indistinguishable from comments typed by hand on the GitHub web UI. Deliberately bounded to defects a reader can settle by looking at the anchored line, rather than a deep audit, so every comment is cheap for the author to check. Scales to 2-20 comments by PR size, parallelises analysis across sub-agents, drafts for approval, then posts individually with human pacing. Use when the user says "review this PR", "review PR 123", pastes a github.com/.../pull/N link, or asks for comments on a pull request. Don't use for reviewing local uncommitted changes or a diff against a branch (use the `review` skill for that).

hainrixz Skill Fix 2Opt-in writer (the /claude-db:fix command). Applies the safe, reversible schema/migration changes from an audit — adding indexes, NOT NULL/CHECK/UNIQUE constraints, missing FKs, type corrections, default/generated columns — as expand-contract migrations. Dry-run preview by default; writes only after explicit per-change confirmation, and only via the migration-writer subagent. Runs only when the user invokes it — never auto-triggered.
-
hainrixz Skill Score 2Recompute and display the two database scores (Design & Integrity + Performance & Scale) from a findings JSON, without re-auditing. Use to re-show or refresh the scores after an audit, to re-score with a different paradigm profile, or to score a saved findings file.

julianobarbosa Bundle Git 2Complete Git version control workflow automation. USE WHEN user mentions commit, push, pull request, PR, branch, merge, rebase, stash, git status, staged files, unstaged changes, OR any version control operations. Handles conventional commits, security checks, and GitHub CLI integration.
-
man-git007 Bundle Senior JS DeveloperUse this skill to write tests and implement code for a JavaScript/TypeScript feature, bug fix, or task from an already-approved implementation plan — writing tests first against the plan's test scenarios, then code against SOLID and OWASP standards, with an approval checkpoint before each phase, before branching and opening a PR. This skill expects an approved plan as input, ideally one produced by the js-feature-planner skill (a plans/*.md file or pasted plan content), rather than a raw user story or issue. If the user wants to jump straight to code without an approved plan, suggest running js-feature-planner first. Trigger on phrases like "implement this plan," "write the tests for this," "let's build this feature" when a plan is available, or "let's code this now."
-
cyl19970726 Bundle Video Content Reconstruction 3Reconstruct a video's full content with an adaptive, evidence-backed two-round workflow. Use when Codex must understand, restore, analyze, convert to an article, document, or audit any video whose important information may live across speech, subtitles, on-screen text, interfaces, actions, parameters, before/after states, examples, claims, counterexamples, or visual transitions. First probe the viewer's intended cognitive change, information carriers, meaning changes, relationship structure, and omission risks; then derive and execute a video-specific capture protocol. Do not route by a closed content taxonomy.
