CI/CD

Analyze and map code structure, data flow, and dependencies in legacy codebases. Use for understanding call stacks, dependency trees, side effects, risk profiles, and generating Mermaid diagrams. Ideal for legacy codebases with zero tests.

Master conceptual analysis methodology - defining concepts through necessary and sufficient conditions. Use for: analyzing concepts, testing definitions, finding counterexamples. Triggers: 'what is X', 'define', 'definition', 'necessary conditions', 'sufficient conditions', 'counterexample', 'conceptual analysis', 'analysis', 'concept', 'essence', 'iff', 'if and only if'.

Audit all filename and naming conventions in the codebase against CLAUDE.md standards and common patterns. Use when user asks to check naming conventions, audit filenames, find naming inconsistencies, or validate file naming patterns.

Physics-inspired story analysis system that treats narrative as trajectories through dimensional space. Tracks dimensions like intimacy, trust, power, and stakes to calculate tension, validate pacing, and diagnose story problems. Genre-aware with formulas for romance, thriller, mystery, and fantasy. Use when analyzing story structure, engineering tension, validating character arcs, diagnosing pacing issues, or generating dimensional targets for scenes.

Query the China Biographical Database (CBDB) API to retrieve comprehensive biographical data about historical Chinese figures. Use this skill when searching for information about Chinese historical figures, scholars, officials, or literary figures from the 7th century BCE through the 19th century CE. Applicable for queries about biographical details, social relationships, official positions, or when users mention specific Chinese names or CBDB person IDs.

Guide users through a structured workflow for co-authoring documentation. Use when user wants to write documentation, proposals, technical specs, decision docs, or similar structured content. This workflow helps users efficiently transfer context, refine content through iteration, and verify the doc works for readers. Trigger when user mentions writing docs, creating proposals, drafting specs, or similar documentation tasks.

Generate comprehensive philosophy and standards documents for any domain (UX design, landing pages, email outbound, API design, etc.). Load when user says "create philosophy doc", "generate standards for [domain]", "build best practices guide", or "create benchmarking document". Conducts deep research, synthesizes findings, and produces structured philosophy documents with principles, frameworks, anti-patterns, checklists, case studies, and metrics.

Plans and executes release and operational readiness tasks, including versioning, changelogs, deployment and rollback.

Designing Slash Commands for Claude Code. Create and optimize slash commands with proper argument parsing, tool permissions, and agent orchestration. Use when building workflow entry points, automation commands, or user-facing shortcuts.

Updated Wave 3 MITM execution skill incorporating Nov 18 platform stability discoveries, domain-specific AI defenses, and WordPress container isolation. Use for Wave 3 challenges with realistic success rates and mitigation strategies.

Write self-documenting code with clear structure and naming, adding minimal concise comments only to explain complex logic sections, avoiding temporal comments about changes or fixes. Use this skill when writing code in any file across the codebase to ensure proper commenting practices. Use this skill when deciding whether to add comments to functions, classes, or complex algorithms, when reviewing existing comments for relevance and evergreen quality, or when refactoring code to be more self-explanatory. Use this skill for Python files, JavaScript/TypeScript files, or any programming language where code documentation is needed. Use this skill when establishing documentation standards, avoiding over-commenting, or removing outdated temporal comments about recent changes.

This skill should be used when debugging web applications, diagnosing page errors, inspecting console output, or capturing screenshots of pages. It provides Chrome DevTools Protocol (CDP) automation via the chromectl.py script for collaborative or automated browser debugging.

Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Claude's capabilities with specialized knowledge, workflows, or tool integrations.

Update documentation files based on recent changes while enforcing project writing guidelines.

Compact YAML format for defining parallel task specifications with scope, boundaries, and agent assignments. Use when creating task files for parallel development.

Work with Gemini File API for document caching and efficient multi-query workflows. Use when discussing file uploads, caching strategies, token optimization, or comparing File API vs inline document approaches.

Build and merge M4B audiobooks on Linux from multiple audio files or multi-part M4B sets, with chapter generation, metadata normalization, UTF-8/Russian encoding handling, and validation. Use when combining MP3/M4A/AAC/FLAC/OGG/WAV into one M4B, merging split M4B parts, or fixing audiobook chapters and metadata.
