Build or refresh the codemunch symbol index for the current project. Walks every source file, extracts all symbols (functions, classes, methods, constants, types) with their exact file location and line range, and writes a fast-lookup index to .claude/codemunch/index.json. Uses LSP when available, falls back to ctags, then ripgrep patterns.

Project Manager role skill. Use when you need to break down tasks, define a WBS, manage dependencies, control delivery pace, or translate confirmed requirements and architecture into an executable task plan. Keywords: task breakdown, WBS, milestones, dependency management, delivery plan, risk control, Sprint planning.

Check domain availability (Available/Taken) for any TLD with confidence scoring, SSL certificate inspection, and IP resolution. Uses 5+ sources in parallel — RDAP, WHOIS (TLD-specific patterns for 30+ ccTLDs/gTLDs, IANA fallback for unknown TLDs), authoritative DNS NS lookup as GDPR tiebreaker for .de/.eu/.at/.ch/.es, DNS A/AAAA, HTTP reachability, and TLS certificate validation. Returns a clear b

Deep Python-specific security audit skill with 50+ vulnerability class coverage across 7 categories. Trigger when auditing Python code: "audit this Python app", "find Python security issues", "check Flask/Django for vulnerabilities", "Python SAST review", "check for pickle vulnerabilities", "review this FastAPI code". Covers misconfiguration, injection, crypto, XSS, deserialization, and ML/AI atta

Use ao gerar código Python para aplicações web, APIs ou ao lidar com entrada de usuário, prevenindo vulnerabilidades do OWASP Top 10 em Django, Flask e FastAPI.

Orientação especializada para desenvolvimento Plone 6 e Volto. Abrange backend (Python, Dexterity, plone.restapi) e frontend (React, Volto, Blocks).

Language-specific vulnerability hotspot reference for manual code audit. Trigger when the user asks to: "what sinks should I look for in Java?", "Python security hotspots", "dangerous functions in Go", "JavaScript injection patterns", or when starting a manual audit of a specific language and needing a sink/source checklist.

Python-specific idioms, philosophy, and expert-level patterns. Use when working with Python code, including Jupyter notebooks (.ipynb). Covers Pythonic thinking, common pitfalls from other language backgrounds, testing ecosystem navigation, type hints trade-offs, and when to use modern Python features.

Install claude-cobrain daemon in direct python3 mode (no LaunchAgent).

HTTP 402 payment protocol for AI agent commerce — three-actor model (Client, Resource Server, Facilitator), ERC-3009 transferWithAuthorization, server middleware (@x402/express), client patterns in TypeScript and Python, facilitator integration, agent-to-agent payments, pricing strategies, and replay protection. Works on Base, Ethereum, Arbitrum, Optimism, Polygon, and Solana.

Object-oriented design principles, patterns, and practices. Use when working with object-oriented languages (Java, C#, C++, Python, Ruby, Swift, etc.) without language-specific skills available, or when applying OOP in multi-paradigm codebases.
