checkpoint SKILL.md skillC
checkpoint from derive-to/derive is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add derive-to/derive/checkpoint@git:20260717.5a980e6Pins git:20260717.5a980e6 in mdr.lock. Pin the fingerprint instead.

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
# checkpoint (commit a layer of working state) Commit a one-page layer of this session's working state to the work's Derive lineage, so any later session — yours tomorrow, a teammate's, another machine — continues cold without re-explaining. Uses the Derive MCP `checkpoint` tool. ## When to fire - A task the user asked for is complete (the natural boundary). - Before a risky or destructive step (the layer is the restore point). - Wrapping up a session, or the user says "checkpoint". Don't wait for a clean ending — sessions get interrupted; checkpoint at the boundary you're at, not the one you hoped to reach. ## How 1. **Find the lineage.** Read `.derive/lineage` at the repo root. If it exists, its content is the lineage's `short_id` — pass it. If not, this is the first checkpoint: call `checkpoint` with `work` (a short name — the feature or branch name) and NO `short_id`, then write the returned `short_id` to `.derive/lineage` so every later session finds it. 2. **Call `checkpoint`** with: - `state` — where the work stands, a few plain sentences a cold reader gets. - `decisions` — each with its why, including approaches rejected (so the next …

How to install
mdr add derive-to/derive/checkpoint@sha256:654591824bd88e10The line at the top of this page pins the label git:20260717.5a980e6, 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.
