Use when a feature has ACs and specs and needs an architecture plan before implementation. Triggers — "/engineer.plan", "plan this feature", "plan the implementation", "design the architecture".
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
# plan
Produce a feature's architecture plan — Checkpoint 4, the most consequential architectural checkpoint. Where engineering authority over **code design** and **performance** is exercised: the agent proposes, the human decides.
Mixed mode — the agent proposes the architecture, the human confirms it, then the rest of the plan is drafted.
## When to use
After `discover-acs` (Checkpoint 2) and `atdd:atdd` (Checkpoint 3). Produces `plan.md`.
If `spec.md` is missing, warn — planning should follow spec formalization — but the user may override and plan from `acs.md` alone (flag the skipped step in the handoff).
**Not for:** Given/When/Then specs (`atdd:atdd`); small changes to an existing plan (`feature-edit`).
## Workflow
**Step 0 — Entry gate.** Before starting, verify the prior checkpoint is complete: run `${CLAUDE_PLUGIN_ROOT}/scripts/dae_handoff.py <feature-dir> --through 3`. On a non-zero exit, **stop** and surface the gap to the human — do not proceed.
Verify branch hygiene: run `${CLAUDE_PLUGIN_ROOT}/scripts/dae_branch.py <feature-dir>`.
On a non-zero exit, **stop** and surface the message to the human — switch

How to install
mdr add swingerman/engineer/plan@sha256:1ca04293e3a63771The line at the top of this page pins the label git:20261020.53d8135, 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.
