Appendix A: Key File Paths Quick Reference
This appendix uses Claude Code’s directory layout as the example (
.claude/commands/,
.claude/agents/, .claude/skills/, .claude/hooks/). See the “Other platforms” section below,
or chapter 13 for the full per-platform layout.Core files
Shipped commands (Claude Code)
On platforms where SessionStart is automatic,
start is not installed as a user-facing command. Agent-less platforms still ship a manual start workflow.
Shipped sub-agents (Claude Code)
Shipped skills (Claude Code)
Hook scripts (Claude Code)
Other platforms
Each platform writes into its own directory (see chapter 13 for the full layout):.cursor/commands/,.cursor/skills/,.cursor/agents/,.cursor/hooks/,.cursor/hooks.json,.cursor/rules/trellis.mdc.opencode/commands/trellis/,.opencode/agents/,.opencode/skills/,.opencode/plugins/.codex/prompts/,.codex/skills/,.codex/agents/(TOML),.codex/hooks/,AGENTS.md.kiro/steering/,.kiro/prompts/,.kiro/skills/,.kiro/agents/.gemini/commands/trellis/(TOML),.gemini/skills/,.gemini/agents/,.gemini/hooks/.qoder/commands/,.qoder/skills/,.qoder/agents/,.qoder/hooks/.codebuddy/commands/trellis/,.codebuddy/skills/,.codebuddy/agents/,.codebuddy/hooks/.factory/commands/trellis/,.factory/droids/,.factory/skills/,.factory/hooks/.github/copilot-instructions.md,.github/prompts/,.github/skills/,.github/agents/,.github/copilot/hooks/.pi/prompts/,.pi/skills/,.pi/agents/,.pi/extensions/trellis/,.pi/settings.json.kilocode/workflows/,.kilocode/skills/.agent/workflows/,.agent/skills/(Antigravity).devin/workflows/,.devin/skills/.agents/skills/(shared cross-platform layer, written by Codex configurator)
