Conciseness

The body is lean with useful sections (Quick Start, Checkpoint Types, Structure, Workflow) and no padding aimed at concepts Claude already knows. The 'Purpose' section ('Creates and manages checkpoints that enable rollback to known-good states...') largely repeats the title and description and could be trimmed, matching anchor 4 ('efficient; minor instances that could be trimmed') rather than anchor 5's every-token-earns-its-place.

Actionability

The Quick Start is real, executable code — 'from scripts.checkpoint_manager import CheckpointManager', 'await manager.create_checkpoint("before-refactor")', 'await manager.restore_checkpoint(checkpoint.id)' — verified against the actual bundle script. It stays at anchor 4 rather than 5 because 'project_dir' is an undefined placeholder, there's no example of error handling or listing checkpoints, and only the happy path is shown.

Workflow Clarity

The Workflow section lists a clear sequence (CREATE → STORE → VALIDATE → RESTORE → VERIFY), but the steps are abstract labels with no commands and no feedback loop (validate → fix → retry) for what is a destructive restore operation. Per the rubric's scoring notes, missing feedback loops on destructive changes cap workflow_clarity at 3; it is not lower because the sequence itself is coherent and validation/verification steps are explicitly named.

Progressive Disclosure

The body is a short, well-organized overview that keeps the full implementation in the bundle file, clearly signaled one level deep: 'See scripts/checkpoint_manager.py for full implementation' — and that file actually exists with the referenced class and methods. Content is appropriately split with easy navigation, matching anchor 5.

Specificity

The description names the domain ('Manage checkpoints for rollback capability') plus 1-2 concrete actions (creating save points, restoring previous states), but the action list ('rolling back changes, managing recovery points, or restoring previous states') is largely synonyms of one capability rather than several distinct actions. It matches anchor 3 ('names domain and 1-2 concrete actions, but not comprehensive'), not anchor 4's 'several specific actions' with only minor gaps.

Completeness

It answers both 'what' ('Manage checkpoints for rollback capability') and 'when' ('Use when creating save points, rolling back changes...') with concrete trigger phrases. The 'what' clause is a single thin statement that doesn't convey what a checkpoint contains or does, so it fits anchor 4 ('when' could be more explicit/the what could be fuller) rather than anchor 5's clearly comprehensive both.

Trigger Term Quality

Natural phrases like 'save points', 'rolling back changes', 'recovery points', and 'restoring previous states' give good keyword coverage a user would plausibly say. It falls short of anchor 5 because common synonyms such as 'snapshots', 'backups', or 'undo' are missing.

Distinctiveness Conflict Risk

Checkpoint/rollback management is a clear niche with distinct trigger terms, so it is mostly distinguishable from unrelated skills. There is minor overlap risk with generic version-control, backup, or git-restore skills, matching anchor 4 rather than anchor 5's minimal conflict risk.
