Conciseness

The body is dominated by lean imperative bullets with no explanation of concepts Claude already knows ('remove filler and meta commentary', 'Avoid vague terms: "handle", "improve"...'). Minor trimming is possible: the persona preamble ('You are a planning/orchestration assistant...'), 'When to Use This Skill' repeating the frontmatter triggers, and overlap between 'Order of operations' and 'Your Output Responsibilities' — efficient but not every token earns its place, so 4 rather than 5.

Actionability

Fully copy-paste-ready guidance for an instruction-only skill: a complete markdown task template, a canonical 8-step section ordering, exact lint messages ('[E]: MISSING — migration task must include a content completeness assertion'), and concrete commands ('grep -h "^status:" real_data/*.md | sort -u', 'uv run plugins/development-harness/scripts/verify_migration_fidelity.py'). Absence of code is not penalized since the guidance is highly actionable, matching the 5 anchor.

Workflow Clarity

Multi-step processes are clearly sequenced ('1. Use CLEAR to structure... 2. Add CoVe only where accuracy risk justifies verification. 3. Control verbosity...') with explicit validation checkpoints and feedback loops ('Revise the output if any check fails or uncertainty remains', 'If any item fails, revise the task prompt'). The pre-finalize linting checklist and scorer-behavior gate provide error-recovery loops, matching the 5 anchor.

Progressive Disclosure

The skill is a single ~285-line file with no references/ bundle; specialized conditional content is inlined — the ~75-line migration section ('four additional [E] criteria are mandatory... before the task scores as CLEAR-compliant') and the swarm-planning guidance apply only to specific task types and could live in one-level-deep reference files. Structure exists (clear headers, template), but content that should be separate is inline, matching anchor 3 rather than 4.

Specificity

Several concrete actions are named: 'Applies CLEAR (Concise, Logical, Explicit, Adaptive, Reflective) to structure and write agent task prompts' and 'adds CoVe (Chain of Verification) checks where accuracy risk is meaningful'. Minor gaps remain (scoring drafts, revising, and linting against CLEAR are core duties in the body but absent from the description), so this sits at anchor 4 rather than 5, and clearly above anchor 3's 1–2 actions.

Completeness

Both what and when are explicit: what — 'Applies CLEAR... to structure and write agent task prompts, then adds CoVe (Chain of Verification) checks'; when — 'Use when orchestration or planning agents are producing task plans, task prompts, or TASK.md instructions' plus 'Activates on draft task prompts, swarm plans, migration tasks, and multi-step plans'. This matches the 5 anchor with concrete trigger phrases.

Trigger Term Quality

Good natural keyword coverage: 'task plans', 'task prompts', 'TASK.md instructions', 'swarm plans', 'migration tasks', 'multi-step plans', plus 'unambiguous, verifiable, and resistant to hallucination'. A few natural phrasings a user might say are missing (e.g. 'write tasks for agents', 'agent instructions', 'worker tasks'), placing it at anchor 4 rather than comprehensive anchor 5.

Distinctiveness Conflict Risk

It occupies a clear niche (task-prompt authoring for worker agents) with distinct triggers like 'TASK.md instructions' and 'swarm plans', but the opening 'Use when orchestration or planning agents are producing task plans' overlaps with general planning/orchestration skills. Minor overlap risk with closely related skills puts it at anchor 4, not 5.
