Write or revise a plan file, proposal, design doc or handoff the user reviews before approving work; carries the Review Card contract and the addendum rules. Use before writing anything into .agent-harness/plans/, and for any markdown deliverable whose job is to get a go/no-go.
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
The trigger lives in the `plan-ceremony` stance. This is the contract. ## Why this exists A plan has two audiences and they are not the same reader. - **The reviewer reviews the approach.** System design, steps, and the decisions that are theirs — in one screen, before they read anything else. - **The implementing agent executes it.** Paths, sequencing, edge cases, evidence. One document written for both produces the 884-line file the reviewer gets lost in. So a plan is one file with a hard seam: a **Review Card** above the first `---`, an **Addendum** below it. **Failure test:** if the reviewer has to scroll to learn what is being built, the plan has failed, however good the work behind it is. ## The Review Card Everything above the first `---`. **Target 50 source lines, hard cap 70**, diagram included. The one thing allowed to push past 70 is a full `## Decisions for the reviewer` block — three lines each, five maximum. Never cut a real decision to hit a budget. Not an introduction to the plan — the whole plan at review altitude. These sections, this order. Do not rename them, do not add to them, do not fold one into another. …

How to install
mdr add jakeselby/agent-harness/plan-authoring@sha256:67b8d8f958017157The line at the top of this page pins the label git:20260928.ca93e6d, 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.
