Test-driven development for behaviour a unit test cannot reach, by writing the expectation against the running app before writing the code. Declare the consequence first, watch it fail, implement, watch it pass. Use when building a user-facing feature, when the user asks for TDD on UI or full-stack work, when a unit test cannot express the outcome that matters, or when you want a red-green loop that runs against the real app instead of mocks.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'agentic-tdd' ] || [ -L ~/.agents/skills/'agentic-tdd' ]; then echo 'A skill folder named agentic-tdd already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/reticlehq/reticle' "$d" && git -C "$d" checkout --quiet '9d5855e46979cfc7e9f7f4de2f2e16200a08921f' -- 'skills/agentic-tdd' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/agentic-tdd' ~/.agents/skills/'agentic-tdd' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'agentic-tdd' ~/.claude/skills/'agentic-tdd' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
