Conciseness

Mostly efficient — no explanations of concepts Claude already knows — but the ~25-line ASCII box diagram and the full JSON dump could be tightened into a short numbered list and a compact schema sketch. Not 4: the box-art borders and complete example JSON are noticeable token padding, not just minor trimming.

Actionability

The Quick Start gives real, executable async Python that matches the actual script API (create_checkpoint with name/description, rollback, rollback_to_latest), all verified to exist. Not 5: common cases like listing, loading, or resuming a checkpoint after a restart are not shown, and no usage is demonstrated for three of the four listed scripts.

Workflow Clarity

The CHECKPOINT WORKFLOW diagram lays out a clear create → attempt → rollback sequence with sub-steps, but rollback is a destructive operation (git reset) and there are no explicit validation/verification steps (e.g., verify checkpoint integrity before reset, confirm state after rollback). Per the rubric, missing validation in destructive operations caps this at 3.

Progressive Disclosure

Section structure is good and the References section is clearly labeled with per-file descriptions, but both referenced files (references/CHECKPOINT-STRATEGY.md, references/ROLLBACK-PROCEDURES.md) do not exist — the references/ directory is absent from the bundle. Not 3: with dangling references, navigation to the detail material fails outright rather than being merely imperfectly organized.

Specificity

"State snapshots and rollback for safe experimentation" names the domain and two concrete actions (snapshots, rollback), but stops there — what state is captured or how is not enumerated. Not 4: an anchor-4 description would list several specific actions with only minor gaps in coverage.

Completeness

Explicitly answers both: what ("State snapshots and rollback for safe experimentation") and when ("Use when creating checkpoints, rolling back changes, managing recovery points, or implementing safe experimentation") with concrete trigger phrases. Not 4: the 'when' clause is already explicit and specific, so the anchor-4 caveat ('when' could be more explicit) does not apply.

Trigger Term Quality

"creating checkpoints, rolling back changes, managing recovery points" gives good natural keyword coverage a user would plausibly say. Not 5: common synonyms like "snapshot", "revert", "undo", or "restore" are missing.

Distinctiveness Conflict Risk

The checkpoint/recovery-point niche is distinct with dedicated triggers. Not 5: "rolling back changes" is broad enough to risk minor overlap with generic version-control or undo-type skills.
