.agents/ — Generic Agent Workflows (Codex / Cursor / etc.)

Path	Purpose
workflows/*-ag.md	11 workflow definitions (mirror of .claude/commands/)

Note: Workflows and commands are currently identical byte-by-byte. If .agents/ is meant to target a different agent runtime (Codex), the variants need to diverge meaningfully.

• _references/ — read-only clones of related OSS projects (LiteLLM, 9router, ClawRouter, CLIProxyAPI, modelrelay, new-api, etc.) for cross-reference during development
• _tasks/ — per-release task tracking files (informal)

Not included in npm pack output. See .npmignore.
