Tools & Utilities
Essential command-line tools and system utilities.
deslop
Remove AI-generated code slop from files or diffs. Use this skill when reviewing AI-generated code to clean up unnecessary comments, defensive code, type hacks, and style inconsistencies. Triggers include "deslop", "remove slop", "clean up AI code", "review for slop".
coding-standard-javascript
Enforce JavaScript/ES6+ and TypeScript coding standards including camelCase variables, PascalCase classes, and kebab-case filenames.
biome-config
Update Biome linting rules, formatting configs, and import organization settings. Use when adding new lint rules, customizing code style, or fixing workspace-specific linting issues.
security-audit
Security vulnerability analysis to detect hardcoded secrets, dangerous patterns, and unsafe code practices.
webapp-testing
Toolkit for interacting with and testing local web applications using Playwright. Supports verifying frontend functionality, debugging UI behavior, capturing browser screenshots, and viewing browser logs.
codesearch-code-search
MANDATORY: Query CodeSearch BEFORE using grep, glob, find, or search. Performs 400x faster semantic and structural code search via SQL on indexed codebase. Use for finding functions, classes, patterns, callers, and implementations. Agents MUST query CodeSearch first; grep is only allowed after CodeSearch returns zero results.
cfn-edit-safety
Pre-edit backup and post-edit validation for safe file modifications. Use when you need to capture file state before edits, validate changes after modifications, revert files to previous state, or ensure edit safety with automatic backup and validation hooks.
ripgrep
Use when searching text in files, codebases, books, or documents. Use when finding files by pattern, searching large files that are too big to read fully, extracting specific content from many files, or when grep/find is too slow. Triggers on "search for", "find occurrences", "look for pattern", "search in files".
release-prep
I want to prepare this project for the next release, which will be {input}. Please do the following:
osgrep-reference
Comprehensive CLI reference and search strategies for osgrep semantic code search. Use for detailed CLI options, index management commands, search strategy guidance (architectural vs targeted queries), and troubleshooting. Complements the osgrep plugin which handles daemon lifecycle.
code-review
Review pull requests and uncommitted code changes. Use when user asks to review a PR, review changes, review uncommitted code, review a diff, or similar code review requests. Activates for phrases like "review this PR", "review my changes", "review before I commit", "check this diff", "review diff", "review commit <sha>".
tampermonkey
Write Tampermonkey userscripts for browser automation, page modification, and web enhancement. Use when: creating browser scripts, writing greasemonkey scripts, automating user interactions, injecting CSS or JavaScript into web pages, modifying website behaviour, building browser extensions, hiding unwanted page elements, adding form auto-fill, scraping website data, intercepting requests, detecting URL changes in SPAs, or storing persistent user preferences. Covers userscript headers (@match, @grant, @require), synchronous and async GM_* API functions, common patterns (DOM mutation, URL change detection, element waiting), security sandboxing, and cross-browser compatibility (Chrome, Firefox, Edge).
colored-output
Centralized colored output formatter for all skills, agents, and commands with ANSI escape codes
devtools
This skill helps launch and configure the Chrome DevTools MCP server, giving Claude visual access to a live browser for debugging and automation. Use when the user asks to set up browser debugging, launch Chrome with DevTools, configure chrome-devtools-mcp, see what my app looks like, take screenshots of my web application, check the browser console, debug console errors, inspect network requests, analyse API responses, measure Core Web Vitals or page performance, run a Lighthouse audit, test button clicks or form submissions, automate browser interactions, fill out forms programmatically, simulate user actions, emulate mobile devices or slow networks, capture DOM snapshots, execute JavaScript in the browser, or troubleshoot Chrome DevTools MCP connection issues. Supports Windows, Linux, and WSL2 environments.
performing-systematic-debugging-for-stubborn-problems
Applies a modified Fagan Inspection methodology to systematically resolve persistent bugs and complex issues. Use when multiple previous fix attempts have failed repeatedly, when dealing with intricate system interactions, or when a methodical root cause analysis is needed. Do not use for simple troubleshooting. Triggers after multiple failed debugging attempts on the same complex issue.
polyflup-history
Chronological log of system improvements and session summaries for PolyFlup.
web-validation
Comprehensive web page validation with authentication, screenshot capture, mobile testing, and enhanced error detection
bundle-analysis
Analyze and optimize JavaScript bundle size, identify large dependencies, and improve load times. Use when bundles are large, investigating performance issues, or optimizing frontend assets.
ts-morph-analyzer
Use when debugging TypeScript/JavaScript bugs by tracing call chains, understanding unfamiliar codebases quickly, making architectural decisions, or reviewing code quality. Extract function signatures and JSDoc without full file reads, trace call hierarchies up/down, detect code smells, and follow data flow. Triggers on debugging, understanding codebase, architectural analysis, signature extraction, call tracing.
chrome-devtools
Control and inspect Chrome browser using Chrome DevTools Protocol - navigate pages, debug network requests, analyze performance, take screenshots, interact with elements, and automate browser tasks.
domain-name-brainstormer
Generates creative domain name ideas for your project and checks availability across multiple TLDs (.com, .io, .dev, .ai, etc.). Saves hours of brainstorming and manual checking.
cfn-compilation-error-fixer
Two-phase compilation error fixer for Rust and TypeScript using Cerebras LLM bulk processing + dedicated agent cleanup. Use when you have 20+ compilation errors that need fast bulk reduction, or when errors are mostly mechanical (type mismatches, missing imports, syntax issues).
