Conciseness

The body is efficient and assumes Claude's competence (no explanations of what agents or parallelism are), but the flat-layout prefix rule is explained twice — once in Prerequisites ("A prefix counts as a domain when 2+ files share it") and again in Step 1 — and the Examples transcript runs long. This matches anchor 4 ('minor instances of over-explanation that could be trimmed') rather than anchor 5's every-token-earns-its-place.

Actionability

As an instruction-only skill the guidance is fully executable: exact glob probe patterns, verbatim menu and message templates ("No agent files found. Checked: [list paths probed]...", "You selected N agents (max 5)..."), concrete spawn parameters (`subagent_type: "general-purpose"`, `prompt: "{agent file content}\n\nTask: {task description}"`), and a worked example transcript. This matches anchor 5 ('copy-paste ready... specific examples cover the common cases').

Workflow Clarity

Five clearly sequenced steps include explicit validation checkpoints and error-recovery feedback loops: a no-files guard that reports probed paths and stops, max-5 enforcement at selection time with a narrowing prompt, and per-agent failure handling ("note the failure inline... and continue"). This matches anchor 5; anchor 4 would require some checkpoints to be merely implicit or missing.

Progressive Disclosure

Sections are well-organized (When to Use, Prerequisites, Configuration, five-step How It Works, Rules, Examples) and everything is one level deep with no nested references, but the ~155-line body is fully inlined including a long example transcript that could arguably live in a separate file. This matches anchor 4 ('good structure... minor organization gaps') rather than anchor 5's clearly split content.

Specificity

"Interactive agent picker for composing and dispatching parallel teams" names the domain and two concrete actions (composing, dispatching), matching the '1-2 concrete actions, not comprehensive' anchor. It falls short of anchor 4 because it does not list several specific actions such as discovering agent files, presenting a domain menu, enforcing team-size limits, or synthesizing results.

Completeness

The 'what' is clear (an interactive picker that composes and dispatches parallel agent teams), but there is no 'Use when...' clause or any equivalent explicit trigger guidance, which caps completeness at anchor 3 per the judging guidelines. It is not anchor 2 because the 'what' is specific rather than vague.

Trigger Term Quality

The description includes some relevant keywords ("agent picker", "teams", "parallel") but is missing natural phrases users would actually say such as "build a team", "browse agents", "pick agents", or "multi-agent". This matches anchor 3 ('some relevant keywords but missing common variations or synonyms') rather than anchor 4's good keyword coverage.

Distinctiveness Conflict Risk

The description carves out a fairly distinct niche (interactive picking and composition of agent personas into parallel teams) with only minor overlap risk against generic multi-agent orchestration or team-creation skills, matching anchor 4. It is not anchor 5 because it lacks distinct trigger phrases that would fully separate it from those related skills.
