Conciseness

The body is lean and every section carries environment-specific information Claude would not already know (sync-before-read ordering, plan path, status markers, git author convention). There is no padding or explanation of concepts Claude already knows, matching anchor 5.

Actionability

Concrete, copy-paste-ready commands are provided (`agentteams-sync`, `git config user.name/user.email` with placeholders) plus a real plan.md path. It stops short of anchor 5 because workflow step 2 ("Execute the task following normal task execution flow") is a vague pointer with no specifics, and "mark it as started in your memory" gives no mechanism.

Workflow Clarity

The workflow presents a clear, correctly ordered 3-step sequence (mark started → execute → @mention report), but step 2 defers to an undefined "normal task execution flow" and there are no checkpoints (e.g., verifying the task is marked in plan.md or confirming the @mention was received). No destructive/batch operations are involved, so the validation cap does not apply; this sits at anchor 4 rather than 5.

Progressive Disclosure

The skill is under 50 lines, single-purpose, needs no external references (no references/, scripts/, or assets/ bundle exists), and the body is organized into clear, well-signaled sections (Gotchas, Project Context, Workflow, Git Config). Per the simple-skill guideline this matches anchor 5.

Specificity

The description lists three domain-specific capabilities — "project plan reading, task coordination with other Workers, and git author config" — which matches the anchor for several specific actions with minor gaps. It falls short of anchor 5 because the actions are stated as nominal phrases rather than a comprehensive, concrete action list (e.g., what plan reading or coordination actually involves).

Completeness

It explicitly answers 'when' with a concrete "Use when you are invited to a Project Room or assigned a task within a multi-worker project" and 'what' with "Covers project plan reading, task coordination with other Workers, and git author config". Both halves are explicit with concrete trigger phrases, matching anchor 5 rather than anchor 4 where the 'when' would be weaker or less specific.

Trigger Term Quality

"invited to a Project Room", "assigned a task", "multi-worker project", and "Workers" are natural phrases a user in this environment would say, giving good keyword coverage. Not anchor 5 because common variations and synonyms (e.g., team project, collaboration, coordinator) are absent; not anchor 3 because the key trigger phrases are present and specific rather than merely 'some relevant keywords'.

Distinctiveness Conflict Risk

"Project Room" and "multi-worker project" establish a clear niche with distinct triggers, and "assigned a task" is qualified by the multi-worker project scope, minimizing conflict with generic task-execution skills. This matches anchor 5; anchor 4 would require noticeable overlap with a closely related skill, which is not evident.
