Use when a user wants to record why one world won over the others, as a decision-diary entry. Not for remote, credential, publish, deploy, or irreversible changes.

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

# Decision diary

## Contract

| Field | Bound contract |
|---|---|
| Trigger | User wants to record why one world won over the others. |
| Authority | Reversible local: writes only one decision-diary entry at the agreed diary location; rollback is version control. No remote mutation. |
| Side effect | A decision-diary entry documenting why one world won. |
| Done | The decision and its rationale are recorded in the decision diary. |

## Inputs

Winning decision: the world or option that won. Required.
Considered worlds: every option that was on the field, including the winner. Required.
Rationale: why the winning world won and why each rejected world lost. Required.
Decision-diary location: the local file path where the entry is appended. Required; if no location is established, the user must supply it.
Optional inputs: date, surrounding context, human opinions, agent doubts, and obvious assumptions that shaped the choice.

## Procedure

1. Confirm the winning decision and the full set of considered worlds from the user. Do not infer a winner or invent options that were not on the field. Done when: the winning decision and all considered worlds are confirmed from the user.

How to install

The exact contents, by fingerprint

mdr add outlinedriven/outline-driven-development/decision-diary@sha256:16b6b5eb9ea580c6

The line at the top of this page pins the label git:20260912.5c5b759, 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.
