Run the pi-lens retrospective — turn a session, an incident, or a merged bug fix into environment changes (checks, hooks, contract lines, deletions), classified mechanical-vs-judgement, each with its red transcript or an issue naming the recurrence. Use at every regroup, after any merged bug fix, on the second round on one defect shape, or when asked "what should we change so this does not recur".
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
# Retro
> Source of truth: `docs/pi-lens-retro.md`. This file is the invocation
> procedure; on any conflict the contract wins.
## Invoke
`/retro` with no argument runs over the current session's ledger and
transcripts. `/retro <PR|issue|run id|"incident: ...">` scopes it to one
incident. The retro is read-only on the repo except for the outputs the
contract names.
## Steps
1. Read `docs/pi-lens-retro.md` in full, then the inputs it names for the
scope: ledger, transcripts, PR bodies and verdicts, CI logs on the exact
head.
2. Collect candidates by category; skip categories with no evidence.
3. Classify each candidate mechanical or judgement. Mechanical is the default.
4. Mechanical: build the check now when it is contained (governance test,
hook, CI job, preflight row) and paste its red on the incident's shape and
its mutation transcript; otherwise file it with the recurrence named.
Judgement: one line in the catalog or the owning role contract.
5. Steering audit: every no-op line names the decision it changed or is
deleted.
6. Record one mistake row per distinct mistake in
`docs/pi-lens-merge-policy.md` ("Common mistakes").
…Read the whole file at its exact version.
How to install
mdr add apmantza/pi-lens/retro@sha256:40a800a14e3624d3The line at the top of this page pins the label git:20260930.dd23166, 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.
