Use this skill when the user asks to "fan out agents", "spawn agents", "use an agent team", "parallel agents", "delegate to subagents", "act as team lead", "orchestrate implementation", "fan out teammates", or when a task decomposes into 2+ independent work items (parallel exploration, one implementer per issue, a multi-lens PR review panel). Covers the basic mechanics of spawning, briefing, supervising, and synthesizing subagents and teammates, plus the hard cap on fleet size.
Use this skill when the user asks to "explore this codebase", "understand this repo", "map the architecture", "review our stack", "get up to speed", "break ground" on an unfamiliar project or research field, "what is the state of this project", "audit the architecture", or before planning changes in a codebase you have not worked in. Produces a verified reconnaissance report before any design or edit.
Use this skill when the user asks to "implement this change", "fix this issue", "add this feature", "make this change properly", "ship this", or for any ordinary single-PR development task: one issue, one branch, one pull request. For multi-phase features use epic-dev; for unfamiliar code run codebase-onboarding first; for failing behavior use the debugging skill.
Execute the project epic development workflow for Codex. Use when the user asks for "epic dev", "epic-dev", "/epic-dev", "run the epic workflow", "create an epic", "resume the epic", "--resume", "--next-phase", "--finalize", phased feature delivery, sprint phases, GitHub sub-issues, or git worktrees for multi-phase implementation.
Use this skill when the user asks to "plan this feature", "write an implementation plan", "design before coding", "think through the approach", "review this plan", or before any multi-file change, architectural decision, experiment with a go/no-go outcome, or strategic pivot. Produces a verifiable plan with pre-registered decision gates and an explicit list of open judgment calls.
Install, update, or audit general user-level AI coding instructions across Claude Code, OpenAI Codex, GitHub Copilot CLI, and Cursor. Use when the user asks to set up global instructions, personal AGENTS.md or CLAUDE.md defaults, configure instructions for multiple agent systems, avoid repeated downstream project rules, install model-routing defaults, or migrate Claude-only user rules to cross-agent user scope.
This skill should be used when the user asks to "update rules", "sync rules", "update AGENTS.md", "update CLAUDE.md", "refresh rules", "update project config", "sync templates", "update vibe rules", "check for rule updates", "update user rules", "update global config", "refresh AGENTS.md", "refresh CLAUDE.md", "sync .rules directory", "what's new in templates", or wants to update existing agent/rules configuration from the latest templates without overwriting customizations.
This skill should be used when executing the epic-dev workflow, creating epic branches, managing sprint phases, working with git worktrees for phased feature development, or when the user mentions "epic dev", "epic-dev", "/epic-dev", "epic workflow", "sprint phases", "phased development", or "git worktree workflow".
