bm-checkpoint SKILL.md skillA

bm-checkpoint from basicmachines-co/basic-memory is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add basicmachines-co/basic-memory/bm-checkpoint@git:20261024.3d433fd

Pins git:20261024.3d433fd in mdr.lock. Pin the fingerprint instead.

Create an immutable Codex handoff in Basic Memory and return an exact bm-orient resume command.

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 Codex Work

Create a durable, immutable handoff note for current Codex work. Use this when
the user asks to checkpoint, wrap up, hand off, remember the work state, or when
the post-compaction SessionStart context requests the deliberate handoff.

When no project is pinned, discover projects with `bm_project(command="list")`
and pass the selected project's external ID as `project` on note/search calls.
With several addressable projects, these calls require an explicit scope even
when a default is configured.

## Gather

Read `~/.codex/basic-memory.json`, then the nearest project
`.codex/basic-memory.json`; project keys override user keys:

- `primaryProject`, default omitted
- `captureFolder`, default `codex/<git top-level directory name>`
- `placementConventions`, optional
- `sessionProfile`, default `general`
- `repository`, required when `sessionProfile` is `coding`

Apply the `bm-writing` skill before drafting the note.

Gather repo evidence:

- the original objective that started the thread and why it mattered
- the latest user intent, including corrections or scope changes that supersede
  the original objective
- the approach taken and why it solves the problem

How to install

The exact contents, by fingerprint
mdr add basicmachines-co/basic-memory/bm-checkpoint@sha256:cc1cc48ffb120870

The line at the top of this page pins the label git:20261024.3d433fd, 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.
