Conciseness

The body avoids explaining concepts Claude already knows and is dense with actionable specifics, but the same content is stated multiple times: the parallel backend/frontend spawn example appears twice ("Canonical command path" and "Step 2"), and the Scheduling, Structural Flow, and Logical Operations sections all restate the plan/spawn/monitor/QA cycle. This matches 'mostly efficient but could be tightened' rather than score 4, which would require only minor trimming.

Actionability

Concrete, mostly executable guidance throughout: a real command path (`oma agent spawn backend <backend-prompt-file> <session-id> --task-id ... -w ./backend &`), specific flags (`--vendor`, `--isolation worktree`, `--read-only`), and a concrete progress-file naming pattern. It is not 5 because the second spawn example uses non-executable literals (`session-id`, `plan.backend_task.id`), and steps like "Verify API contracts align between agents" state what to do without a concrete check.

Workflow Clarity

The sequence is explicit (Entry -> PREPARE/ACT/VERIFY/FINALIZE -> Steps 1-4) with a dedicated QA validation step and a recovery section containing feedback loops ("pause downstream frontend/mobile work until backend/API contract is reconciled", "rerun affected checks before finalizing"). It is not 5 because several checkpoints are named but not operationalized (how to detect contract divergence or stalled progress), and the duplicated three-section structure mildly obscures which flow to follow.

Progressive Disclosure

Structure is good: well-labeled sections with shared policy details pushed to clearly signaled one-level-deep references (`../_shared/core/collaboration-policy.md`, `../_shared/core/execution-policy.md`, `../_shared/runtime/memory-protocol.md`) plus a closing References section. It is not 5 because no references/ bundle exists in the skill directory itself, the cross-directory shared files cannot be verified from this bundle, and the ~170-line body retains duplicated content that could be consolidated or split.

Specificity

"Coordinate assigned specialist tasks and handoffs manually" names the multi-agent coordination domain and two actions (coordinate tasks, handoffs), but they are abstract verbs without more concrete capability detail, matching the 'domain plus 1-2 concrete actions' anchor. It is not score 4 because no additional specific operations are enumerated, and not score 2 because the actions are more than a bare generic claim like 'Processes PDF files'.

Completeness

Both parts are explicitly present: 'what' ("Coordinate assigned specialist tasks and handoffs manually") and 'when' ("Use when supervising a multi-agent project step by step"), so the score 3 cap for a missing trigger clause does not apply. It is not 5 because the 'when' is a single scenario and the 'what' is thin relative to the 'concrete trigger phrases plus comprehensive what' exemplar.

Trigger Term Quality

"Use when supervising a multi-agent project step by step" supplies natural phrases users would say ('multi-agent', 'supervising', 'step by step', 'handoffs'). It falls short of the score 5 anchor because common synonyms like 'delegate to agents', 'orchestrate', or 'spawn agents' are absent, and it clearly exceeds the score 3 'some keywords, missing variations' example.

Distinctiveness Conflict Risk

"manually" and "supervising" carve out a niche distinct from an automated orchestrator skill, giving minor overlap risk only with closely related orchestration skills. It is not 5 because the description does not state the automated-orchestrator boundary, so a user asking for generic 'agent orchestration' could trigger it over a sibling skill.
