Conciseness

The body is operational and free of basic-concept padding, but the runtime background-handling guidance is stated at length in step 7 and then largely repeated in the 'Always Do This' bullets (Codex yield_time_ms, nohup, heartbeat cadence), and the num_molecules range / flat $0.025 cost points are restated — fitting 'Mostly efficient but includes some unnecessary explanation or could be tightened'; not a 4 because the redundancy is more than minor.

Actionability

Quotes a copy-paste-ready command block with concrete flags ('estimate-cost', 'start --idempotency-key ... --raw-output --transform id', 'download-results --poll-interval-seconds 60') and explicit placeholder-substitution instructions, covering the common submit-and-download flow — matching 'Fully executable; copy-paste ready code or commands; specific examples cover the common cases'.

Workflow Clarity

Quotes an 8-step sequenced workflow with explicit validation checkpoints ('Enforce 10 <= num_molecules <= 1,000,000 before calling estimate-cost', 'show the USD cost, wait for explicit confirmation'), an 'Always Do This' checklist, and feedback loops for auth/sandbox failures and detached-download restart — matching 'Clear sequence with explicit validation steps; feedback loops for error recovery; checklists'; the batch-operation cap does not apply because validation is present.

Progressive Disclosure

Quotes well-signaled one-level-deep references to real files ('Read [references/api.md](references/api.md) for exact shapes', '[references/results.md](references/results.md) for output layout') with API shapes and results layout appropriately split out, but the verbose runtime-specific heartbeat/background instructions live inline in SKILL.md rather than a dedicated reference, fitting 'Good structure; most content is appropriately placed; minor organization gaps'; not a 5 because of that inline bulk.

Specificity

Quotes 'Design new small-molecule binders with Boltz' — it names the domain and one concrete action, but lists only a single primary verb rather than multiple specific actions, matching the anchor 'Names domain and 1-2 concrete actions, but not comprehensive'; it is not a 4 because no additional distinct actions are enumerated.

Completeness

Quotes 'Design new small-molecule binders with Boltz' (what) and 'Use when generating novel ligands or hits for a target without a fixed compound library' (when) with an explicit negative boundary 'Not for screening existing molecules or one-off docking' — clearly and explicitly answers both what and when with concrete trigger phrases, matching the top anchor.

Trigger Term Quality

Quotes 'novel ligands or hits for a target', 'fixed compound library', 'screening existing molecules', and 'one-off docking' — good natural keyword coverage including negative triggers, but missing common synonyms like 'drug candidates' or 'lead compounds', fitting 'Good keyword coverage; a few natural terms missing'; not a 5 because coverage is not comprehensive.

Distinctiveness Conflict Risk

Quotes 'without a fixed compound library' and 'Not for screening existing molecules or one-off docking' — a clear niche with an explicit boundary against the sibling screening/docking skills, minimal conflict risk, matching 'Clear niche with distinct triggers; minimal conflict risk'.
