Set up a project's meta-structure for agentic engineering — CLAUDE.md, AGENTS.md, docs/, README, and CHANGELOG. Use when starting a new project or retrofitting an existing codebase for the forge workflow.
Stay current with how OpenCode, OpenAI Codex, and Claude Code implement extensibility features (skills, slash commands, subagents, custom prompts). Use when comparing implementations across AI coding assistants, researching how a specific tool implements a feature, or syncing knowledge about agent extensibility patterns. Triggers include questions like "how does X implement skills?", "compare slash commands across tools", "what's the latest on Claude Code sub-agents?", or requests to understand agent extensibility approaches.
Mermaid Class Diagram Generator - Auto-activating skill for Visual Content. Triggers on: mermaid class diagram generator, mermaid class diagram generator Part of the Visual Content skill category.
Use when appending structured perf investigation notes and evidence.
Explore a codebase with parallel Haiku agents. Modes - --fast (1 agent), default (3), --deep (5). Use when user says "learn [repo]", "explore codebase", "study this repo".
Analyzes changes since last release and updates CHANGELOG.md ONLY. Does NOT trigger releases.
Use when changes are ready to ship and you need to communicate what changed, who it affects, and any required actions without exposing internal-only details.
Write unambiguous specifications using EARS (Easy Approach to Requirements Syntax) patterns. Provides 6 sentence templates that eliminate ambiguity: Ubiquitous, Event-driven, State-driven, Unwanted behavior, Optional feature, and Complex. Use when: "EARS", "specification writing", "write specs", "仕様を書く", "EARS記法", "仕様を明確化", "requirements specification", "unambiguous specification".
Write READMEs for software projects. The skill should be used when writing or revising a README or README.md file.
Use when coordinating non-trivial implementation work, executing implementation plans, or modifying AGENTS.md/CLAUDE.md.
Generate high-quality, "All-Star" README files for open-source repositories. Use this skill when a user asks to create, update, or improve a README.md file for their project.
Analyze repository structure and generate or update standardized AGENTS.md files that serve as contributor guides for AI agents. Supports both single-repo and monorepo structures. Measures LOC to determine character limits and produces structured documents covering overview, folder structure, patterns, conventions, and working agreements. Update mode refreshes only the standard sections while preserving user-defined custom sections. Use when setting up a new repository, onboarding AI agents to an existing codebase, updating an existing AGENTS.md, or when the user mentions AGENTS.md.
