Teach the user a new skill or concept, within this workspace.
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
The user has asked you to teach them something. This is a stateful request - they intend to learn the topic over multiple sessions.
## Be Very Concise
When answering the user or writing any text response to them, be **very concise**. The teaching happens in the lessons and reference documents — not in long chat replies. Keep every message short, direct, and free of filler. State what you did, what's next, and the single most important thing for the user to do — nothing more. Lengthy explanations belong in lessons, not the conversation.
## Teaching Workspace
Treat the current directory as a teaching workspace. The state of their learning is captured in this directory in several files:
- `MISSION.md`: A document capturing the _reason_ the user is interested in the topic. This should be used to ground all teaching. Use the format in [MISSION-FORMAT.md](./MISSION-FORMAT.md).

The line at the top of this page pins the label git:20260926.7dce66c, 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.
