skill-tdd
Host: Codex CLI — This skill was designed for Claude Code and adapted for Codex. Cross-reference commands use installed skill names in Codex rather than
/octo:*slash commands. Use the active Codex shell and subagent tools. Do not claim a provider, model, or host subagent is available until the current session exposes it. For host tool equivalents, seeskills/blocks/codex-host-adapter.md.

The Iron Law
Violating the letter of this rule is violating the spirit of this rule.
Write code before the test? Delete it. Start over.
- Don't keep it as "reference"
