Claude Skills by Mathews-Tom

Gate-oriented safety audit for code changes before landing, using a checklist with two-pass severity triage. Triggers on: "is this safe to land", "pre-landing review", "safety check before merge", "gate check", "/pre-landing-review". NOT for diff review, use pr-review.

Scaffolds per-repository agent context so coding agents share the same issue tracker rules, triage label vocabulary, domain glossary, ADR layout, and handoff conventions. Triggers on: "set up project context", "configure agent docs", "create CONTEXT.md", "setup agent workflow", "agent issue tracker setup", "triage labels", "domain glossary for agents". Use when a repo needs durable context files before planning, triage, debugging, TDD, architecture review, or multi-agent implementation.

LLM prompt engineering: analyzes failure modes, generates variants (direct, few-shot, CoT), designs rubrics, produces test suites. Triggers on: "prompt engineering", "generate prompt variants", "A/B test prompts", "optimize prompt", "improve this prompt". NOT for SKILL.md files, use skill-evaluator.

Systematic web application QA testing with issue taxonomy, health scoring, and regression tracking. Triggers on: "QA this", "test the app", "smoke test", "run QA", "systematic test", "regression test", "full QA", "/qa-systematic".

Evaluates RAG pipeline quality across retrieval (precision, recall, MRR) and generation (groundedness, hallucination rate). Triggers on: "audit RAG pipeline", "RAG quality", "hallucination detection", "why is RAG failing", "grounding check". NOT for general architecture audits, use architecture-reviewer.

> **DEPRECATED** — Modern Claude models produce accurate, well-explained regex patterns > with edge-case test suites natively, including multi-language usage examples. The uplift > delta from this skill approaches zero. Retained for archival reference only. Transforms matching requirements (positive and negative examples) into tested regex patterns with component-by-component explanations, capture group documentation, edge case identification, and ready-to-use code in Python and JavaScript.

Create motion graphics and videos using Remotion (React) with audio sync, web fonts, and TailwindCSS. Triggers on: "create a Remotion video", "React video", "motion graphics", "branded video", "product demo video", "video with voiceover". NOT for math animations, use concept-to-video.

Full security audit for public repositories across 12 attack surfaces: git history, secrets, CI/CD, containers, dependencies, licenses. Triggers on: "push to GitHub", "make repo public", "open source this", "is this safe to push", "release audit", "secret leaks".

Critical analysis of research papers evaluating methodology, claims-evidence alignment, and contribution significance. Triggers on: "critique this paper", "review this research", "analyze this study", "evaluate the methodology", "is this paper sound". NOT for formatting or submission readiness, use manuscript-review.

> **DEPRECATED** — Opus 4.7 uses adaptive thinking (optional at each step) and Sonnet 4.6 > handles structured chain-of-thought natively. For most tasks, prompting "Think carefully > and step-by-step; this is harder than it looks" elicits the required depth. This > methodology is retained as a reference pattern when deterministic, reviewable reasoning > traces are required (audits, proofs, post-hoc analysis) regardless of the model's > adaptive-thinking choice. Structured, reflective problem-...

Automated release pipeline: merges main, runs tests, pre-landing review, version bump, changelog, bisectable commits, and PR creation. Triggers on: "ship it", "release this", "prepare for release", "open a PR", "push and PR", "land this", "/ship-workflow".

Converts Opus-quality skills into deterministic Haiku-executable workflows via trace-driven distillation and cross-model validation. Triggers on: "distill this skill", "make this skill work on Haiku", "cross-model optimization", "optimize skill for cost". NOT for code simplification, use code-refiner.

Agent-native catalog and installer for armory packages across all 7 types. Browse, search, install, update, and remove without leaving session. Triggers on: "list available packages", "install skill", "armory install", "armory search", "/library list", "package catalog".

Analyzes SQL queries for missing indexes, N+1 patterns, suboptimal joins, and full table scans. Interprets EXPLAIN, detects anti-patterns, rewrites queries. Triggers on: "optimize this query", "slow query", "add indexes", "explain plan", "N+1 query", "why is this query slow".

Manages dependent branch stacks and stacked pull requests using safe Git topology rules. Triggers on: "create stacked PRs", "publish this stack", "sync my PR stack", "rebase this stack", "merge the stack", "retarget child PRs", "split this branch into stacked PRs", "validate this stack", "cleanup stacked branches". Use when local branches or one source branch need to become a dependency-ordered PR stack with correct parent bases, validation, synchronization, merge order, and cleanup.

Build self-contained static HTML artifacts opened in a browser: interactive diagrams, dashboards, infographics. Pure HTML5+CSS3+inline SVG, zero toolchain. Triggers on: "interactive HTML", "open in browser", "HTML artifact", "visual dashboard", "HTML infographic". NOT for PNG/SVG output, use concept-to-image.

Generates structured test assertions and failure diagnostics for skill packages from a definition and task prompt. Triggers on: "verify this skill", "generate assertions", "surrogate verification", "diagnose skill failure". NOT for code review, use pr-review.

Produces phased task boards from feature requests: dependency-mapped work items, parallelization flags, risk flags, edge cases, test matrices. Triggers on: "decompose this feature", "task breakdown with dependencies", "phased implementation plan", "work breakdown structure". NOT for effort estimates, use estimate-calibrator.

AI-optimized web search via Tavily API when no URL is provided. Returns clean AI-ready snippets for current info and news. Triggers on: "search the web", "look up online", "find recent information", "web search". NOT for known URLs, use web-fetch.

Generates pytest test suites with happy path, edge cases, error conditions, fixture scaffolding, mocks, async patterns. Triggers on: "generate tests", "write tests for", "test this function", "create test suite", "pytest for", "unit tests for", "mock strategy for".

Triggers on: "review UX", "audit this page", "redesign the dashboard", "UX review", "improve the layout", "dashboard UX audit", "component recommendations".

Web content fetching via curl and WebFetch when a specific URL is provided. Covers HTTP GET/POST, JSON APIs, HTML, auth, cookies. Triggers on: "fetch this URL", "download HTML", "call this API", "curl this endpoint". NOT for search, use tavily.
