checkpoint from qwerfunch/cladding is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Record a feature checkpoint event pinning the current git HEAD plus a spec digest, so a later rollback can restore the exact pre-change state. Use before a non-trivial feature implementation, before a refactor that touches many files, or whenever the user wants a known-good safety net the autonomous drive loop can fall back to. Activate only when the connected project contains spec.yaml or the user explicitly names Cladding; ignore ordinary requests in uninitialized projects.
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
# Cladding checkpoint Run `clad checkpoint <featureId>` from the project root. Iron Law backbone Phase 1 (iron-law.md §2.5) — the verb only **stamps** the audit-log entry; it never mutates the working tree or invokes `git commit`. The maintainer keeps the option to freeze the state with a normal git commit on top. The checkpoint event payload carries: - `featureId` — the spec id, accepts both `F-NNN` legacy and six-or-more-hex hash shapes; newly authored records emit `F-<hash8>`. - `gitHead` — full 40-char commit sha at the time of the call (or `null` when the project is not a git repository). - `specDigest` — sha-256 over the merged spec for replay verification. - `timestamp` — ISO 8601. ``` clad checkpoint F-001 clad checkpoint F-a3f9c2e1 ``` The output is a single Pulse line: `✓ checkpoint · <featureId> head=<sha12> digest=<digest12>`. The event lands in `.cladding/events.log.jsonl` as `type: "feature_checkpoint"` and can be inspected with `clad doctor --json` or `clad_get_events` over MCP. ## When to use - Before starting a feature with your AI host so a failed attempt has a known-good target to roll back to. …

How to install
mdr add qwerfunch/cladding/checkpoint@sha256:1d1d19a04fcf9da8The line at the top of this page pins the label git:20260905.d56eea5, 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.
