Conciseness

The body is lean and imperative with zero padding: it never explains concepts Claude already knows, and every line is operational (paths, formats, rules, a numbered resume flow). Matches the 5 anchor 'every token earns its place'; nothing to trim toward the 4 anchor.

Actionability

Fully executable guidance throughout: exact file paths ('/root/agentteams-fs/shared/tasks/{task-id}/progress/YYYY-MM-DD.md'), a copy-paste 'mc cp' push command, an exact log-entry format, a concrete task-history.json example, and explicit LRU rules. Copy-paste ready with no gaps, matching the 5 anchor.

Workflow Clarity

The resume flow is a clear 4-step numbered sequence with one fallback ('if not there, check history-tasks/{task-id}.json'), and the history-management rules are unambiguous. It falls short of the 5 anchor because there are no explicit validation checkpoints or error-recovery steps (e.g., what to do when spec.md or plan.md is missing from task_dir).

Progressive Disclosure

The skill bundle has no references/, scripts/, or assets/ directories, and the ~60-line body is self-contained with well-organized sections (Gotchas, Progress Log, Task History, Resume Flow) where every piece of content is operational and belongs inline. Per the rubric's simple-skill guidance, this earns the 5 anchor with no need for external references.

Specificity

Names several concrete actions ('progress logging, plan updates', 'resuming a task after session reset', 'managing task history') plus concrete artifacts ('progress log format, task-history.json, and resume flow'). Falls just short of the 5 anchor because 'plan updates' is offered as a trigger but is not reflected in the stated coverage of topics.

Completeness

Explicitly answers 'when' with three concrete trigger clauses ('Use when executing a task..., when resuming a task after session reset, or when managing task history') and answers 'what' explicitly ('Covers progress log format, task-history.json, and resume flow'). This matches the 5 anchor's requirement for explicit what-and-when with concrete triggers, and is clearly stronger than the 4 anchor, whose caveat is a less-explicit 'when'.

Trigger Term Quality

Includes natural phrases a user or coordinator would say — 'executing a task', 'progress logging', 'resuming a task', 'session reset', 'managing task history', 'task-history.json'. Good coverage, but common synonyms like 'continue a task' or 'pick up where you left off' are missing, so it does not reach the 5 anchor's comprehensive synonym coverage.

Distinctiveness Conflict Risk

Distinctly anchored to a niche via 'task-history.json', 'session reset', and 'progress log', but the opening trigger 'when executing a task' is broad enough to overlap with generic task-execution or planning skills. Mostly distinct with minor overlap risk, fitting the 4 anchor rather than the 5 anchor's 'minimal conflict risk'.
