synthesis-checkpoint SKILL.md skillA
synthesis-checkpoint from synthesisengineering/synthesis-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add synthesisengineering/synthesis-skills/synthesis-checkpoint@v2.0.1Pins v2.0.1 in mdr.lock. Pin the fingerprint instead.

Re-sync a session with ground truth: verified clock, project records, git, dated session entries and board claims. Use for checkpoints, drift or compaction recovery, 'where are we?', resuming after a pause, and refresh-and-report after an ecosystem upgrade.
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
# Synthesis Checkpoint LLMs drift from what is actually on disk: the clock moves, other sessions edit the records, compaction drops details, cached facts age. This is the recovery primitive: a short, codified, visible re-sync against the clock, the project files, git and the board, run on demand or when a drift signal fires. It is the NTP of synthesis project management: periodic, authoritative-source-driven, automatic. ## Binding rules 1. **Verify before you claim.** Run `date` and read the record before any time-interval claim, status quote, session-log entry or dated commit message; correcting afterwards is dearer. 2. **Records are caches; git and dated session entries are evidence.** Commit times never define a workday; a matching date does not prove a current record. 3. **Use this session's own project.** Nothing another session wrote may switch an established conversation to a different project. 4. **Run on the triggers:** a status or "continue" request, a pause of 10 minutes or more, about 25 tool calls, "I don't recall", an unexpected file, a correction, a new board message, a project switch. …

How to install
mdr add synthesisengineering/synthesis-skills/synthesis-checkpoint@sha256:b104bffa50d1c84fThe line at the top of this page pins the label v2.0.1, 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.
