Auto-generates a changelog from git commits, sprint data, and design documents. Produces both internal and player-facing versions.
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
Read the argument for the target version or sprint number. If a version is given, use the corresponding git tag. If a sprint number is given, use the sprint date range.
Verify the repository is initialized: run `git rev-parse --is-inside-work-tree` to confirm git is available. If not a git repo, inform the user and abort gracefully.
---
## Phase 2: Gather Change Data
Read the git log since the last tag or release:
```
git log --oneline [last-tag]..HEAD
```
If no tags exist, read the full log or a reasonable recent range (last 100 commits).
Read sprint reports from `production/sprints/` for the relevant period to understand planned work and context behind changes.
Read completed design documents from `design/gdd/` for any new features implemented during this period.
---
## Phase 3: Categorize Changes
Categorize every change into one of these categories:
- **New Features**: Entirely new gameplay systems, modes, or content
- **Improvements**: Enhancements to existing features, UX improvements, performance gains
- **Bug Fixes**: Corrections to broken behavior
- **Balance Changes**: Tuning of gameplay values, difficulty, economy

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.
