Use to orchestrate a team-based ATDD workflow — six phases (spec writing, spec review, pipeline generation, implementation, refine, verify & harden) each handled by a fresh agent so no role erodes across a long-running feature. Triggers — "build a feature with a team", "use ATDD with agents", "create an ATDD team", "orchestrate agents for ATDD", "coordinate agents for feature development", "add ATDD roles to my team", "add spec-writer and reviewer to the team".
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
# Team-Based ATDD Workflow Orchestrate an agent team that follows the Acceptance Test Driven Development workflow. The team lead coordinates specialist agents through six phases. Each phase is run by a **fresh agent invocation** — no agent persists across phases. ## Why fresh per phase A long-lived agent's context compacts as a feature runs for hours. Compaction silently erodes role identity and discipline: agents lose their role, invent constraints that do not exist, and skip expensive-but-required steps. A fresh per-phase agent reloads its instructions clean — the same insight as the engineer plugin's per-skill model. The "team" exists for **parallelism** across features, not for keeping agents alive within one feature. ## Team Detection Before spawning phase agents, check for existing teams: 1. Read `~/.claude/teams/` to list active teams. 2. If a team exists, present the user with a choice: - **Extend** — run the ATDD phases for this feature alongside the existing team. - **Replace** — shut down the existing team and run ATDD fresh. - **New team** — run the ATDD pipeline as a separate team. If no team exists, proceed directly. ## Roles …

How to install
mdr add swingerman/engineer/atdd-team@sha256:046b6b62c088f869The line at the top of this page pins the label git:20261020.a98004e, 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.
