Tool Adapters — thin pointers, not prompt dumps

AGENTS.md is the universal contract. The instantiated AGENTS.md at the project root is the source of truth; Codex reads it natively, and most modern agents (Claude Code, Cursor, Antigravity) do too. This folder holds the tiny per-tool adapter files that point each tool at it. Every adapter is a pointer — never a copy of AGENTS.md content.

Where each file goes

The 18 vibe-* files above are optional slash-command shortcuts — one per workflow stage (research → build), mirroring the Claude Code skills in .claude/skills/. Each is a thin wrapper that defers to the root part*.md files as the single source of truth. Invoke with /vibe-research etc. in Cursor and Antigravity, or /prompts:vibe-research in Codex (restart Codex after copying so it picks the prompts up; Codex prompts are user-level only, so they work in every project but can't live inside one).

Notes

• Cursor: the .mdc frontmatter (description, alwaysApply: true) makes the rule load in every chat. Legacy .cursorrules still works but is deprecated — delete it if one exists.
• Antigravity: current versions read AGENTS.md natively; the .agent/rules/ file is an always-on workspace rule that reinforces it. Global (all-project) rules live in ~/.gemini/GEMINI.md.
• Codex: see codex/README.md. Optional: personal reusable prompts in ~/.codex/prompts/.
• Any other tool (Gemini CLI, Copilot, Windsurf, Lovable…): open its custom-instructions feature and paste: "Read AGENTS.md — it is the source of truth for this project. Details in agent_docs/."
