Pulls a prior session's checkpoint as fenced, scrubbed recovery context. Use when the user is continuing prior work; skip it on a fresh, unrelated task.
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
# Resume Checkpoint (pull tool) A model-invokable tool that fetches and judges a prior session's checkpoint **on demand**, when the user is continuing prior work and the SessionStart pointer was not enough (or was declined). ## When to call Call this skill when the user is **continuing prior work** and you need the prior session's context to proceed efficiently: - The user says "continue", "resume", "pick up where we left off", "what were we working on", or names a prior task/topic. - A `⤸resumable` statusline signal is showing and the user's ask relates to prior work. - The SessionStart pointer offered a checkpoint and the user's first prompt confirms they intend to resume. ## When NOT to call (negative trigger) Do not call this on a fresh, unrelated task. It costs ~300 tokens per call. A no-match returns one line, but calling it on every fresh session wastes the tokens the pointer gate was built to save. If the user's opening is clearly a new, self-contained task with no reference to prior work, do not call. ## What it returns - The single best-scoring checkpoint (content relevance, IDF-weighted), or a one-line "No relevant checkpoint found." …

How to install
mdr add alexgreensh/token-optimizer/resume-checkpoint@sha256:83a5b5674c7092ddThe line at the top of this page pins the label git:20261010.d43ebe5, 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.
