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.

Save a deliberate work checkpoint to Basic Memory with the story, changed files, verification, decisions, blockers, and the next action. Use when the user asks to checkpoint, wrap up, hand off, or remember the state of the work.

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 Claude Work

Create a durable handoff note for the current work. Use this when the user asks
to checkpoint, wrap up, hand off, remember the state of the work, or before a
long context transition. This is the deliberate, high-signal counterpart to the
automatic PreCompact checkpoint.

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

Resolve config: read the `basicMemory` block with the same precedence the hooks
use. For the user-level base, append `settings.json` to the literal value of
`CLAUDE_CONFIG_DIR` when that environment variable is present; do not trim it,
expand `~`, or treat an empty value as unset. Use `~/.claude/settings.json` only
when the variable is absent. Then the project's `.claude/settings.json` and
`.claude/settings.local.json` override it per key:

- `primaryProject`, optional; discover and explicitly select the listed default or sole project when absent
- `captureFolder`, default `sessions`
…

How to install

The exact contents, by fingerprint
mdr add basicmachines-co/basic-memory/bm-checkpoint@sha256:873da5ef6a7f7ddd

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.
