Scaffold, review, upgrade, or diagnose agent skills against best-practice frontmatter, progressive disclosure, token-aware structure, and the agent-skills.git symlink + inventory wiring. Modes: scaffold (default — new skill), review (audit existing skill), upgrade (split a single-file skill into multi-file), diagnose…

Authors, audits, and maintains project documentation across CLAUDE.md / .claude/rules/, AGENTS.md, README.md, and Diátaxis docs/ trees (root + nested for monorepos). Four modes: init scaffolds a tiered docs setup from scratch; update detects drift (dead @imports, renamed commands, stale narrative) and incrementally…

Audits CLAUDE.md files (root, nested, .claude/rules/.md) for context bloat and emits ranked suggestions across two levers — (1) shrink inventory entries, (2) flag rarely-used agent-invokable skills that should become slash-only to drop their description from the always-on available-skills list. Triggers on Claude…

Persists context across conversations as plain markdown so every future session can enrich a topic-scoped memory (e.g. parenting, relationship-anna, work-history, project-acme). Four operations: write (extract candidates, resolve as ADD / UPDATE / DELETE / NOOP per Mem0), read (load a ≤ 200-line INDEX; fetch detail…

Generates a personal markdown changelog of merged or closed pull requests authored by the current user and Linear tickets the user closed or worked on, over a configurable window (default 7 days), grouped by feature area (e.g. Dashboards, Agent0). Inputs sourced from gh search prs --author=@me and the Linear MCP. Use…

Diagnoses a failed CI check, classifies it with an explicit verdict (code-bug | workflow-bug | dep-bug | env-bug | flaky | unsure), confidence-gates the fix (>=90 auto, 80-89 ask, <80 escalate), applies it, pushes, and iteratively verifies until CI passes — reverting the last commit if a brand-new failure appears.…

Generate a short, narrative GitHub pull request description (≤ 25 lines, hard ceiling 40), push the branch, open the PR as a draft, then run the review-loop skill for a bounded review-apply-simplify convergence before finalizing. The review-loop (pr-reviewer → implement-suggestion → polish simplify, up to 5…

Selects the right chart type and visualization library for React/Next.js (web) and Expo/React Native (mobile) data visualization tasks, then applies accessibility and anti-pattern guardrails. Maps data shape and intent (comparison, composition, distribution, relationship, evolution, flow, geographic, hierarchical) to…

Scaffolds, audits, and tests Storybook stories for React (web) and React Native / Expo (native) component libraries. Generates three artefacts in two files per invocation: a visual regression .stories.tsx file containing a Default story (variants grouped into a single snapshot) and a Playground story (interactive args…

Reviews UX, accessibility, and microcopy for web and React Native (Expo) applications. Analyzes UI code against established UX principles, WCAG 2.2 accessibility standards, platform guidelines (Apple HIG, Material Design 3), and UX writing best practices. Triggers on: "ux review", "review ux", "check accessibility"…

Reviews and guides LLM/AI application engineering: prompt design, prompt caching, multimodal inputs, RAG, agent loops and tool design, resilience (rate limits, retries, fallbacks), memory, model migration, evals, testing, prompt-injection defence, and observability. Synthesises practices from Anthropic, OpenAI…
Skill Claude CodeCodex
Language-agnostic skill for authoring and reviewing code with low cognitive complexity, readability, and long-term maintainability. Covers guard clauses, single-responsibility functions, type-driven design (illegal states unrepresentable, branded primitives, discriminated unions), schema-first validation, single…

Rates confidence that the current work fully solves the stated requirement. Supports plan validation, code review, and analysis (root-cause, refactor, diagnose) modes. Plan mode combines LLM judgment with deterministic rule checks (multi-signal gate); a failed rule caps the gate at 89% regardless of LLM score. Use…
Skill Claude CodeCodex
Adversarially challenges a proposed plan, code change, or bug diagnosis from a hostile pre-mortem perspective. Walks a fixed taxonomy of failure modes, blast radius, rollback, hidden coupling, and maintainability; every finding must cite a file, line, or named assumption; forces a steelman of at least one alternative.…

Developer Experience (DX) review and advisory skill for CLI tools, shell scripts, developer tooling, and automation. Analyzes code against established CLI design guidelines (clig.dev, Heroku CLI Style Guide, 12 Factor CLI), composability principles, error handling best practices, and developer ergonomics. Triggers on…

Ensures every delivery ships with the telemetry needed to prove its impact and catch its own regressions: RUM/analytics events for user-facing web changes (delegates to rum-tracking), OpenTelemetry traces/metrics/structured logs for new or changed API endpoints, and explicit error/warning signal paths so failures…
Skill Claude CodeCodex
Reviews whether a change takes the most optimal approach for its stated intent and, when it does not, researches the code, validates a concretely better approach via holistic analysis, and either proposes it (report mode) or applies it behind a confidence gate (apply mode). Judges four axes — codebase-fit, simplicity…

Re-runnable pre-PR quality gate for the current branch. Composes two existing passes over the branch diff: a broad pr-reviewer pass (read-only review via the branch's open PR, which pr-reviewer requires) and a code-quality simplify pass (applies Class M mechanical refactors behind a confidence ≥ 90 % gate, reverting…
