Record reconciled final outcomes to history.md, not intermediate requests or obsolete claims.

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

## Context

History files are cold-start context, not the source of truth for live behavior. Stale or incorrect
entries poison decision-making downstream. A stale-history incident proved that an old history claim
can cause future spawns to repeat a reversed decision. Reconcile an operational claim with current
implementation, workflows, tests, documentation, skills, and applicable decisions before acting on it.

## Patterns

- **Record the final outcome**, not the initial request.
- **Wait for confirmation** before writing to history — don't log intermediate states.
- **If a decision reverses**, update the entry immediately — don't leave stale data.
- **Link authority for operational facts.** Name the current source or workflow when a lesson
  depends on live behavior.
- **Promote reusable rules.** Move procedures and incident lessons that future roles need into a
  focused skill; history should retain only the evidence and outcome.

## Examples

✓ **Correct:**
- "Migration target: v0.8.17 (initial target was later corrected before execution)"
- "Node runtime: follow the current `package.json` `engines.node` requirement"

✗ **Incorrect:**

How to install

The exact contents, by fingerprint
mdr add bradygaster/squad/history-hygiene@sha256:2b5a282b5bd8aa22

The line at the top of this page pins the label git:20260911.f640e80, 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.
