Generates a sprint or milestone retrospective by analyzing completed work, velocity, blockers, and patterns. Produces actionable insights for the next iteration.
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
## Phase 1: Parse Arguments
Determine whether this is a sprint retrospective (`sprint-N`) or a milestone retrospective (`milestone-name`).
---
## Phase 1b: Check for Existing Retrospective
Before loading any data, glob for an existing retrospective file:
- For sprint retrospectives: `production/retrospectives/retro-[sprint-slug]-*.md`
(also check `production/sprints/sprint-[N]-retrospective.md` as an alternate location)
- For milestone retrospectives: `production/retrospectives/retro-[milestone-name]-*.md`
If a matching file is found, present the user with:
```
An existing retrospective was found: [filename]
[A] Update existing retrospective — load it and add/revise sections
[B] Start fresh — generate a new retrospective, archiving the old one
```
Wait for user selection before continuing. If updating, read the existing file and
carry its content forward into the generation phase, revising sections with new data.
---
## Phase 2: Load Sprint or Milestone Data
Read the sprint or milestone plan from the appropriate location:
- Sprint plans: `production/sprints/`
- Milestone definitions: `production/milestones/`
**If the file does not exist or is empty**, output:

The line at the top of this page pins the label git:20260621.096f040, 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.
