io.github.joe-bell/cva/security-review

Security code review for vulnerabilities. Use when asked to "security review", "find vulnerabilities", "check for security issues", "audit security", "OWASP review", or review code for injection, XSS, authentication, authorization, cryptography issues. Provides systematic review with confidence-based reporting.

io.github.nexu-io/open-design/html-ppt-zhangzara-capsule

A year-end self-review for a product manager — the role, the outcomes, the learning, and the ask, all evidence-backed. Built as a decision-grade career deck for manager, review committee.

io.github.nexu-io/open-design/html-ppt-zhangzara-retro-windows

An IT security-awareness training on spotting phishing — the tells, the drill, and what to do in the first 60 seconds. Built as a decision-grade professional training deck for all employees.

io.github.handsontable/handsontable/react-wrapper-dev

Use when developing or modifying the @handsontable/react-wrapper package - React components, hooks, settings mapping, selection preservation during updateSettings, and the wrapper's TypeScript prop types and generated .d.ts. Use this whenever a task touches HotTableProps/HotColumnProps typing or IDE autocomplete for <HotTable>/<HotColumn> props, the declaration build, or a report that React/TypeScript users get no prop suggestions - even if the wrapper is not named explicitly.

io.github.liuzhengdongfortest/CodeStable/cs-refactor

Refactor 主入口。触发：优化/重构/拆分/性能/代码太长，且不改变行为、不新增需求。不要用于新增功能(cs-feat)、修复 bug(cs-issue)、对外文档(cs-docs)、大需求拆解(cs-epic)。

io.github.apache/shardingsphere/review-pr

Used to review whether an Apache ShardingSphere PR truly fixes the root cause, assess side effects and regression risks, and judge code correctness or mergeability from public evidence. If not mergeable, produce committer-tone change requests or needs-discussion feedback when the PR direction, root-cause model, or problem framing should be reopened. Also use for GitHub-visible PR discussion, review comments, challenged findings, and copy-ready committer replies where review correctness, mergeability, change-request validity, or root-cause evidence is being judged. Supports full-coverage ledger review for high-risk or explicitly anti-drip requests, and self-iterates before final output.

io.github.microsoft/vscode/agent-host-logs

Analyze Agent Host debug log exports. Use when given an ah-logs or ahp-logs zip/folder, an Export Agent Host Debug Logs bundle, events.jsonl, AHP JSONL transport logs, Agent Host.log, remote-agenthost.log, or copilot-logs.

io.github.microsoft/vscode/code-oss-logs

Find and read timestamped process logs from Code OSS dev builds, including main.log, renderer.log, extension host logs, and agenthost.log. For bundles produced by Export Agent Host Debug Logs, use agent-host-logs.

io.github.Yeachan-Heo/oh-my-codex/code-review

Run a comprehensive code review

io.github.DietrichGebert/ponytail/ponytail

Lazy senior dev mode for any coding task (write, refactor, fix, review): YAGNI, stdlib first, no unrequested abstractions. Not for non-coding requests.

io.github.DietrichGebert/ponytail/ponytail

Forces the laziest solution that actually works, simplest, shortest, most minimal. Channels a senior dev who has seen everything: question whether the task needs to exist at all (YAGNI), reach for the standard library before custom code, native platform features before dependencies, one line before fifty. Supports intensity levels: lite, full (default), ultra. Use on ANY coding task: writing, adding, refactoring, fixing, reviewing, or designing code, and choosing libraries or dependencies. Also use whenever the user says "ponytail", "be lazy", "lazy mode", "simplest solution", "minimal solution", "yagni", "do less", or "shortest path", or complains about over-engineering, bloat, boilerplate, or unnecessary dependencies. Do NOT use for non-coding requests (general knowledge, prose, translation, summaries, recipes).

io.github.compozy/compozy/writing-tech-post

Authors engineering blog posts end-to-end: launch deep-dives, incident postmortems, architecture migrations, performance case studies, tutorials, AI/agent system writeups, security disclosures, and research-to-product translations. Picks the correct archetype, plans the abstraction ladder, enforces an evidence cadence (diagrams, benchmarks, profiles, traces, code, ablations), tunes voice against publisher house styles (Datadog, Vercel, GitHub, AWS, Meta, Cloudflare, Jane Street), and runs a pre-publish gate for narrative momentum and disclosure ethics. Use when drafting a new engineering post, restructuring a draft that feels flat, deciding which evidence form belongs where, validating that depth and product context are balanced, or preparing a postmortem, migration, or performance narrative for external publication. Do not use for API reference documentation, README authoring, marketing copy, release notes, generic SEO content, ghost-written executive thought leadership, or non-engineering long-form essays.

io.github.compozy/compozy/writing-skills

Author, refactor, and debug agent skills. Use when creating a new skill from scratch, pruning or restructuring a bloated SKILL.md, tightening a skill description's triggers, or diagnosing bundled references the agent ignores. Don't use for agent instruction files like CLAUDE.md or AGENTS.md (use agent-md-refactor), general documentation, or READMEs.

io.github.compozy/compozy/refactoring-analysis

Audits a codebase for refactoring opportunities using Martin Fowler's code smell and technique catalog — long functions, duplication, high coupling, complex conditionals, primitive obsession — and writes a prioritized report to docs/_refacs/. Use when auditing code quality, planning a refactoring sprint, or reviewing architectural health; not for style/formatting, performance, or security audits.

io.github.compozy/compozy/testing-boss

Testing doctrine for tests that reveal bugs instead of passing for the wrong reason — spanning software and LLM/AI systems. Use when authoring or reviewing tests, adding a mock, deciding where a test belongs, letting a coding agent generate tests, triaging flaky CI, designing an eval suite for an LLM/agent feature, or rebuilding a brittle suite. Not for general code review, library debugging unrelated to tests, CI pipeline design beyond tests, or production observability.

io.github.compozy/compozy/typescript-advanced

Master TypeScript's advanced type system including generics, conditional types, mapped types, template literals, and utility types for building type-safe applications. Use when implementing complex type logic, creating reusable type utilities, or ensuring compile-time type safety in TypeScript projects. Don't use for plain JavaScript, runtime validation libraries (Zod, Yup), or basic TypeScript syntax questions.

io.github.openai/plugins/security-diff-scan

Use when the user asks for a security review of a pull request, commit, branch diff, working-tree patch, or other Git-backed change set.

io.github.openai/plugins/security-scan

Use for a standard, single-pass security audit of an entire repository or a scoped path, package folder, or submodule with no diff to review. This is the default repository scan. Do not use for PR/commit/branch/working-tree diffs, or for deep, multi-pass, or variance-reducing scans.

io.github.github/awesome-copilot/mcp-implementation-security-review

Review the implementation source code of MCP (Model Context Protocol) servers, clients, and tool handlers against a security baseline — authentication, sessions, rate limiting, input-schema validation, official-SDK usage, RCE vectors, and the OWASP MCP Top 10 — producing a report with file/line evidence. Use this skill when: - Reviewing an MCP server implementation for security before release - Checking a server against the baseline controls (MCP-01 to MCP-05) and the OWASP MCP Top 10 - Auditing tools for RCE vectors (command/code injection, unsafe deserialization, path traversal, SSTI, dependency hijacking, SSRF) - Verifying auth, session, rate-limiting, and input-validation controls on a network-exposed server - Reviewing MCP client code that handles untrusted server responses and session IDs - Requests like "review this MCP server for security" or "is my MCP server implementation secure?"

io.github.ScriptedAlchemy/tracedecay/automation-run-review

Use when Review self-improvement automation runs and activation policy.

io.github.posit-dev/py-shiny/testing

Use when writing or running end-to-end tests for a Shiny for Python (py-shiny) app - launching an app under pytest, locating and asserting on UI components (inputs, outputs, cards, navsets), simulating user interaction with Playwright, or when tempted to hand-roll CSS selectors, raw Playwright locators, or sleep() waits against Shiny-rendered HTML.

io.github.browserbase/skills/browser

Automate web browser interactions using natural language via CLI commands. Use when the user asks to browse websites, navigate web pages, extract data from websites, take screenshots, fill forms, click buttons, or interact with web applications. Supports remote Browserbase sessions with Browserbase Identity, Verified browsers, automatic CAPTCHA solving, and residential proxies — ideal for protected websites and JavaScript-heavy pages.
