Agent skills for agentic coding tools. Extremely opinionated. Updated (almost) daily.
Skill Claude CodeCodex
Use when auditing comments, docstrings, or embedded documentation prose in a scope — to strip bloat and rewrite cluttered-but-justified entries. Triggers on "audit comments", "clean up docstrings", "strip stale comments", "comment cleanup".
Skill Claude CodeCodex
Use when the goal is to reduce code size, remove unnecessary complexity, or simplify a module without removing user-facing behavior.
Skill Claude CodeCodex
Use when auditing and fixing end-to-end contracts and compatibility in a scope — HTTP/RPC APIs, events/messages, schemas, files, CLIs, libraries, configuration, database consumers, and external integrations. Triggers on "audit contracts", "API compatibility review", "schema compatibility audit", "check…
Skill Claude CodeCodex
Use when auditing and fixing logic bugs in a scope — off-by-one, wrong operator, inverted condition, unhandled boundary cases, unit/dimension mismatch, code that doesn't do what its name or docstring claims. Triggers on "audit correctness", "fix logic bugs", "check for off-by-one", "correctness review".
Skill Claude CodeCodex
Use when auditing and fixing end-to-end data integrity in a scope — invariant violations, partial or conflicting writes, unsafe migrations/backfills, duplicate or reordered effects, precision or time corruption, stale derived stores, broken retention/deletion, and unrecoverable drift. Triggers on "audit data…
Skill Claude CodeCodex
Use when auditing and fixing error handling in a scope — swallowed exceptions, defaults returned on error, optional chaining masking missing data, floating promises / missing awaits, entry points with no error boundary, resource leaks on error paths. Triggers on "audit error handling", "hunt silent failures", "fix…
Skill Claude CodeCodex
Use when auditing and fixing logging in a scope — missing observability, INFO bloat that doesn't scale, stale or wrong-level messages, payload dumps on routine paths. Triggers on "audit logs", "fix logging", "logging review", "clean up log noise".
Skill Claude CodeCodex
Use when cutting code in a folder that doesn't earn its keep — whether a solution is over-engineered, where maintenance cost can be reduced, or where a feature should be removed entirely.
Skill Claude CodeCodex
Use when auditing and unifying pattern consistency in a scope — divergent implementations of the same concern, reimplementations of existing utilities, naming violations, import disorder, unused dependencies. Triggers on "audit patterns", "fix inconsistencies", "unify conventions", "fix reimplementations", "pattern…
Skill Claude CodeCodex
Use when auditing and fixing performance hot paths in a scope — N+1 queries, overfetching, wasted recomputation, blocking hot paths, unbounded growth. Triggers on "audit performance", "fix slow paths", "check for N+1", "performance review".
Skill Claude CodeCodex
Use when auditing and fixing reliability or resilience in a scope — timeouts, retries, idempotency, partial failure, dependency outages, overload, failover, recovery, reconciliation, and startup/shutdown behavior. Triggers on "audit reliability", "review resilience", "failure recovery review", "resilience audit"…
Skill Claude CodeCodex
Use when auditing and fixing security in a scope — injection (SQL, shell, template), auth/authz gaps, secrets in code or logs, weak crypto, missing validation at trust boundaries, XSS, SSRF, path traversal. Triggers on "audit security", "security review", "fix vulnerabilities", "OWASP check". Performs a comprehensive…
Skill Claude CodeCodex
Use when auditing repo topology in a scope — code grouped by type where the repo groups by feature, god-modules, misplaced files, leaky or missing module boundaries, layer-direction violations, import cycles, over-nesting. Triggers on "audit structure", "repo structure review", "fix module boundaries", "check…
Skill Claude CodeCodex
Use when the user wants a thorough audit of the existing test suite — aggressively cutting tests that exist just to exist, rewriting weak ones to actually catch the bugs they should, identifying production code that is uncovered or thinly covered, and adding tests where coverage would catch real defects. Trigger on…
Skill Claude CodeCodex
Use when running the full audit sweep on a scope — runs all focused audit dimensions (necessity, structure, patterns, contracts, correctness, data integrity, error handling, logs, perf, reliability, security, tests, complexity, comments) as an isolated parallel workflow that integrates in dependency order. Triggers on…
Skill Claude CodeCodex
Use when the user asks to commit, create a git commit, checkpoint changes, save work to git, or write a commit message.
Skill Claude CodeCodex
Use when the user wants a UI/UX/frontend build request rewritten into an expert design brief before an LLM builds from it. Rewrites the prompt, never executes it; sharpens vague gestures into named techniques, makes implicit constraints explicit, and surfaces absent load-bearing dimensions as author-facing fill slots…
Skill Claude CodeCodex
Use when the requested deliverable is distinct competing approaches to compare before choosing what to implement.
Skill Claude CodeCodex
Use when the user wants an independent expert review of work done in this conversation before accepting or extending it.
Skill Claude CodeCodex
Use when the user asks to merge another branch into the current branch, pull upstream changes without rebasing, or resolve merge conflicts.
Skill Claude CodeCodex
Creates and rigorously edits concise, credible, native-sounding Czech or English business writing. Use for one-pagers, executive communication, management documents, B2B marketing, PR, proposals, presentations, websites, sales materials, cold outreach, emails, announcements, localization, and rewriting. Requires…
Skill Claude CodeCodex
Use when a task needs an implementation-ready design document before code changes begin.
Skill Claude CodeCodex
Use when the user asks to create or update a pull request for the current branch.
Skill Claude CodeCodex
Use when the user asks to create, refine, evaluate, or optimize an LLM system prompt.
