Open source contribution best practices with PR validation scripts. Use for pull requests, community contributions, or encountering personal artifacts in PRs, working on main branch, untested submissions, unrelated changes, unfocused PRs.
Manages GitHub assets branch for persistent image hosting in PRs. Creates orphan branch, uploads files, generates raw URLs. Bypasses transient CDN tokens. Triggers on keywords: assets branch, upload screenshots, pr images, persistent images, github assets
Rewrites git history safely with dry-run-first workflow. Supports commit amending, squashing, rewording, tag updates, and force pushing. Always proposes plan before execution. Triggers on keywords: rewrite history, squash commits, amend commit, fix commit, update tags, rebase history, clean history, fix tag
Use when receiving code review feedback (especially if unclear or technically questionable), when completing tasks or major features requiring review before proceeding, or before making any completion/success claims. Covers three practices - receiving feedback with technical rigor over performative agreement, requesting reviews via code-reviewer subagent, and verification gates requiring evidence before any status claims. Essential for subagent-driven development, pull requests, and preventing false completion claims.
Search the web using Exa AI for real-time information retrieval. Use when users ask to search online, find current information, look up recent events, or need data beyond knowledge cutoff. Triggers on "search the web", "find online", "look up", "what's the latest on", "search for".
Control JetBrains IDE programmatically for file operations, code analysis, refactoring, and terminal execution. Use when users want to interact with IntelliJ/WebStorm/PyCharm, run configurations, refactor code, or analyze files. Triggers on "open file in IDE", "run configuration", "refactor", "find files in project", "IDE terminal".
Run verification commands and confirm output before claiming success. Use when about to claim work is complete, fixed, or passing, before committing or creating PRs.
Detect test smells, overmocking, flaky tests, and coverage issues. Analyze test effectiveness, maintainability, and reliability. Use when reviewing tests or improving test quality.
Implements API rate limiting using token bucket, sliding window, and Redis-based algorithms to protect against abuse. Use when securing public APIs, implementing tiered access, or preventing denial-of-service attacks.
Configures HTTP security headers to protect against XSS, clickjacking, and MIME sniffing attacks. Use when hardening web applications, passing security audits, or implementing Content Security Policy.
This skill should be used when the user asks to "add turnstile", "implement bot protection", "validate turnstile token", "fix turnstile error", "setup captcha alternative", or encounters error codes 100*/300*/600*, CSP errors, or token validation failures. Provides CAPTCHA-alternative protection for Cloudflare Workers, React, Next.js, and Hono.
Validate at every layer data passes through to make bugs impossible. Use when invalid data causes failures deep in execution, requiring validation at multiple system layers.
Validate Spectr specifications and change proposals without requiring the spectr binary USE WHEN you're in a sandboxed or restricted execution context and spectr is not available in your path. DO NOT USE WHEN you need a lightweight alternative for task acceptance, but have the spectr binary available. DO NOT USE when you have the spectr binary available.
Comprehensive testing guide for Cloudflare Workers using Vitest and @cloudflare/vitest-pool-workers. Use for test setup, binding mocks (D1/KV/R2/DO), integration tests, or encountering test failures, mock errors, coverage issues.
Create minimal subtests to isolate and fix complex bugs. Use when a test fails and the issue is buried in complexity.
Use this when updating the codex submodule or when patch files in codex-patches/ need to be added, regenerated, or repaired.
Accept Spectr change proposals by converting tasks.md to tasks.jsonc without requiring the spectr binary. USE WHEN you're in a sandboxed or restricted execution context and spectr is not available in your path. DO NOT USE WHEN you need a lightweight alternative for task acceptance, but have the spectr binary available. DO NOT USE when you have the spectr binary available.
