Conciseness

The body is lean, imperative, and assumes Claude's competence — no concepts are over-explained — with only minor redundancy: the worktree prohibition is stated in the Core Contract ('Do not create or suggest worktrees'), the child prompt template ('Do not create a worktree'), and Success Criteria ('Worktrees are not created'). That repetition could be trimmed but the rest earns its tokens, so it sits above anchor 3 and below the perfectly lean 5.

Actionability

Guidance is copy-paste ready: exact commands ('$orchestrator on/off/status'), seven exact tool names to search for, a ready-to-send child prompt template, a thread title format ('<BRANCH-OR-TICKET> <short task title>'), and a concrete status table schema. These cover the common creation, routing, and status cases the skill will actually face.

Workflow Clarity

Routing Rules is a 9-step sequence with explicit decision points (per-branch vs not, branch key resolution fallbacks, found vs not found) and error-recovery guards: 'If mode state is unclear, ask once before executing locally', 'If these tools are not available, stop and report', and a required child closeout report of branch key, PR URL, blockers, and next owner. The Success Criteria section functions as an explicit checklist. This is not the 4 anchor because checkpoints are not merely 'mostly present' — every risky branch (missing mapping, missing tools, unclear mode, concurrent same-checkout work) has an explicit guard.

Progressive Disclosure

The skill is a single ~150-line file with no bundle directories (references/, scripts/, assets/ do not exist), and the body makes no dangling file references — all sections are well-labeled and navigable. It is not the 5 anchor because that expects clearly signaled one-level-deep references splitting detail out (e.g. the child prompt template or status table could live in a reference file), though at this length a single well-organized file is defensible.

Specificity

The description names several concrete actions — 'Turn the current Codex thread into a coordination thread', 'routes per-branch implementation work to durable reusable child threads', 'without worktrees' — which goes beyond the 1-2-action anchor but stops short of comprehensive coverage of what the skill does (mode toggles, status reporting, thread reuse, safety rules).

Completeness

The 'what' is clear (turn the thread into a coordination thread routing work to child threads), but there is no 'Use when...' clause or equivalent explicit trigger guidance, which caps completeness at 3 per the judging guidelines. It is not a 2 because the 'what' is specific and concrete, not vague.

Trigger Term Quality

Relevant keywords exist ('Codex thread', 'coordination thread', 'child threads', 'worktrees') but they lean toward internal jargon ('durable reusable child threads', 'per-branch'), and natural user phrases like 'orchestrate', 'delegate', or 'dispatch work' are missing. It clearly lists relevant terms yet lacks common variations, so it is not the sparse 2 or the well-covered 4.

Distinctiveness Conflict Risk

'Codex thread', 'per-branch', 'child threads', 'without worktrees' carve out a distinct orchestration niche with mostly unique triggers, with only minor overlap risk against generic delegation/subagent skills. It is not a 5 because the trigger vocabulary is jargon-adjacent and a user asking broadly to 'delegate' or 'parallelize' work could plausibly match other skills.
