Produce an ATDD-first implementation plan in Claude Code's native plan mode, with named design patterns called out where they earn their keep. The skill enters plan mode automatically (via the EnterPlanMode tool), runs /flagrare:codebase-explore to ground the plan in the actual codebase, then produces a plan-mode plan that MUST include both: (1) 3-5 acceptance tests in plain English defining 'done' before any implementation, written behavior-first against the public API only; and (2) any…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# ATDD Plan

This skill produces an implementation plan in **Claude Code's native plan mode**. It does not reinvent plan mode's output shape, Claude already knows how to write a plan-mode plan. The skill exists to enforce three things plan mode alone won't:

1. **Plan mode is actually used**: `EnterPlanMode` at skill start, `ExitPlanMode` at skill end. The user gets the native approve/edit/reject button UI, not a wall of markdown.
2. **The plan is grounded in the real codebase**: `/flagrare:codebase-explore` runs before any planning, so the plan references the actual files, conventions, and reusable pieces that exist.
3. **The plan contains the two non-negotiables below.**

Everything else about the plan's form, length, section ordering, tone, follows plan mode's defaults. Don't impose extra structure on top.

**REQUIRED BACKGROUND:** Invoke `/flagrare:testing-philosophy` before writing the Acceptance Tests. It defines, layer-agnostically, what a good test is, behavior over implementation, the Testing Trophy, and the e2e necessity floor below. The AT rules here are its application to planning; read both.

How to install

The exact contents, by fingerprint
mdr add flagrare/agent-skills/atdd-plan@sha256:5af8bceec5bd3f42

The line at the top of this page pins the label git:20261002.8acabf4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
