Advisory copy-edit of prose — reports grammar, logic, and flow issues as suggestions without rewriting the text. Use when the user asks to 'check grammar', 'proofread', 'copy-edit', 'find errors in', or 'review the writing' of an article, email, doc, or post, and wants to keep control of the wording. Not for removing…

Use when: the user asks you to check, rewrite, humanize, or de-slop English text that shows signs of AI generation (ChatGPT, Claude, Gemini, Grok, DeepSeek, GPT-5, Qwen, Llama, any LLM). Trigger for requests like: 'humanize this', 'make it sound human / natural', 'remove the AI voice', 'this reads like a chatbot', 'AI…

Read-only, mechanical audit of a landing or marketing page's conversion structure — single primary CTA per view, form-field friction, ad-to-headline message match, trust/social-proof presence, above-the-fold value, and CLS-safe banners/interstitials — producing evidence-backed findings and a SHIP / FIX / BLOCK verdict…
Skill Claude CodeCodex
Audit a public-facing client (browser extension, mobile/desktop app, SPA, CLI, SDK, or any open-sourced client that talks to a private backend) so its public surface stays self-contained and doesn't help attackers. Use when asked to review a repo for leaked backend internals, secrets, or abuse-enabling disclosure; to…

Applies structured logging, levels, PII handling, and wide-event (canonical log line) patterns. Use when adding or reviewing logs, choosing log levels, designing request logging, after an incident where logs were insufficient or leaked data, or when the user says 'logging', 'log format', 'what should we log'…
Skill Claude CodeCodex
Runs an authorization-gated penetration-test engagement against a target (repo, web app, API, network, cloud, or mobile client) following PTES, OWASP WSTG/MASTG/API Top 10, and NIST SP 800-115 — from scoping and rules of engagement through recon, attack-surface mapping, testing, exploitation-to-proof, and a findings…
Skill Claude CodeCodex
Read-only audit of performance and reliability — event-loop discipline, streaming and backpressure, memory/CPU diagnostics, production shutdown/timeout/job habits, cross-service resilience topology (circuit breakers, retry budgets, queue bounds, dual-writes), and frontend delivery (Core Web Vitals, bundle size…
Skill Claude CodeCodex
Read-only regression sweep over a codebase and its live surfaces: a layered aspect pass (typecheck, lint, generated-artifact drift, unit and integration suites, black-box wire contract, cross-implementation parity, downstream consumer build) compared against a recorded baseline so the answer is deltas, plus nine…
Skill Claude CodeCodex
Structured root-cause analysis for incidents, recurring failures, and process problems that have no failing test to run — 5-Whys, fishbone, PDCA, and a one-page A3 write-up. Use for a postmortem, incident retro, 'why does this keep happening', quality or process breakdown, or 'find the root cause' of a non-code issue.…
Skill Claude CodeCodex
Audits code for common vulnerabilities: injection, secrets, auth, dependency CVEs, CI/CD pipeline exposure, and cryptographic misuse — with confidence-gated, evidence-backed findings mapped to CWE/OWASP. Use when reviewing security, before a release, after adding auth/payments/sensitive-data handling, when hardening…
Skill Claude CodeCodex
Read-only SEO and AI-discoverability audit of a site or codebase — technical SEO, generated-page (programmatic SEO) safety, and agent/LLM readability — producing evidence-backed findings and a SHIP / FIX / BLOCK verdict. Use when the user asks to 'audit my SEO', 'check for thin content / cannibalization', 'will Google…

Removes installed agent skills from every AI agent on the machine — Claude Code, Codex, Gemini CLI, Cursor, Copilot, opencode, Amp, Windsurf, and any other agent that reads a skills/ directory — behind a keep list that can spare one collection, this skill alone, or a named set. Cross-platform by construction: the…
Skill Claude CodeCodex
Audits a repository for machine-written 'AI slop' markers across every surface — code, comments, tests, docs, configs and CI — against a verified catalog: glyph pockets, stale and false comments, change-narration, drift-bait numbers, template stamps, misleading prefixes, impossible defensiveness, copy-paste drift…
Skill Claude CodeCodex
Learns a website's writing style by deep-crawling it in a live browser and distills a reusable style guide (voice, tone rules, lexicon, rhythm, structure, golden samples), then rewrites any documents or page sources in that voice with a cross-document consistency pass. Use when the user says 'learn the style of '…
Skill Claude CodeCodex
Designs and writes tests that catch real regressions — placement (unit/integration/E2E), factories and fixtures, behavior-first assertions, characterization tests for legacy code, property/fuzz tests for parsers. Use when asked to 'write tests', 'add test coverage', 'test this module', 'напиши тесты', when a bug fix…

Translate Russian text of any kind into natural English while preserving every structural element, formatting marker, link, identifier, and the author's human voice. Use when translating Russian articles, docs, prose, fiction, marketing copy, technical content, transcripts, or any other Russian-language text to…
