Conciseness

The ~30-line body is lean and efficient: it opens with a one-line purpose ("Use this skill for current AgentTeams topology and runtime state"), gives three executable commands, and states rules without any padding or explanation of concepts Claude already knows. Every token earns its place, matching the 5 anchor.

Actionability

The bash block is copy-paste ready with env-var fallbacks ("${AGENTTEAMS_WORKER_CR_NAME:-$AGENTTEAMS_WORKER_NAME}") and a jq pipeline to chain team lookup, and the failure paths are concrete ("If team-scoped queries are denied, ask your coordinator"). It falls short of 5 only because "Use `agt` CLI when available" leaves the unavailable-CLI fallback undefined — a minor gap in the executable path.

Workflow Clarity

This is a simple, single-purpose skill and the task is unambiguous: the three commands form an implicit sequence (get own worker → extract team CR → list team workers), and both failure modes have explicit escalation checkpoints (denied queries → ask coordinator; missing metadata → "ask your coordinator. Do not guess."). Per the simple-skill guidance this earns a 5.

Progressive Disclosure

The skill is under 50 lines with no need for external references (no references/, scripts/, or assets/ files exist), and its sections (Source Of Truth, What To Use It For) are well-organized with clearly labeled negative guidance and routing rules. Per the under-50-lines guideline, well-organized sections alone justify a 5.

Specificity

Names several concrete lookup targets ("team topology, worker phase, runtime state, or identity") plus an explicit scope exclusion ("Do not use for standard task flows"), matching the 'several specific actions with minor gaps' anchor. It stops short of a 5 because it never states how the lookup is performed or what the skill returns.

Completeness

Both are present: what ("look up team topology, worker phase, runtime state, or identity") and when ("Use only when you need to... that is NOT available from the current message context"). Not a 5 because the 'what' side is thinner — the mechanism and output of the lookup are left unstated, so the trigger guidance is more explicit than the capability description.

Trigger Term Quality

Good keyword coverage: "team topology", "worker phase", "runtime state", "identity", "coordinator", and "meta.json.room_id" give strong natural-term coverage for this domain. A few plausible synonyms (e.g. 'worker status', 'team members', 'room ID lookup') are missing, so it fits the 4 anchor rather than comprehensive 5.

Distinctiveness Conflict Risk

The description is unusually well-scoped: an explicit positive trigger ("Use only when you need to look up... NOT available from the current message context") and an explicit negative trigger ("Do not use for standard task flows — the coordinator is the message sender"). This clear niche with stated exclusions minimizes conflict risk, matching the 5 anchor.
