Conciseness

Mostly efficient, rule-dense prose with no basic-concept padding, but the paid-pilot workspace rules (no customer workspace, the docs/production-paid-call-verification.md runbook, the one-case acceptance) are restated across Workflow step 11, the 'Automatic publication and verification' section, and the Invariants, and step 11 is a run-on paragraph that could be tightened. Not 2 because the majority of sections (Core model, steps 1-10, UI navigation) are lean with every sentence carrying a rule.

Actionability

Concrete, executable commands throughout — 'deepline search "<transition input -> transition outcome>" --type plays', 'deepline plays settings set --play <name> --name path --value ...', 'deepline plays get <name> --source --live' — plus a concrete '.play.ts' shape and the 'billing.maxCreditsPerRun' setting. Not 5 because the central artifact (the orchestrator Play) is shown only as an inline signature fragment ('export default async function (input: EngineInput) { ... }') rather than a complete example, and no sample table schema is given.

Workflow Clarity

A clearly sequenced 11-step workflow with an explicit validation step ('Validate every edge' enumerating invalid states, child failures, and replay of a completed transition) and a separate dependency-ordered publication checklist with per-step verification ('read its Live version and Live max credits per run lines') and explicit stop-on-failure feedback loops. Matches the anchor for explicit validation steps, error recovery, and checklists; the paid/batch operations all carry verification, so no cap applies.

Progressive Disclosure

Good section structure and one clearly signaled, real, one-level-deep reference ('Read references/state-machine-contract.md when designing the transition table, Customer DB table roles, Play shape, and tests'), whose content matches the promise. Not 5 because the ~50-line publication/pilot runbook and the long Deliverable list are inlined in SKILL.md where a second reference file would keep the overview leaner; not 3 because the reference is clearly signaled and structure is solid.

Specificity

Names several concrete actions — 'Build, publish, and verify a Deepline Play as a durable state machine over Customer DB tables, including a small paid pilot' — plus a concrete artifact and storage target. Not 5 because coverage has minor gaps (transition Plays, table contracts, deliverables are unmentioned); not 3 because it lists more than 1-2 specific actions.

Completeness

Explicitly answers both: the 'what' ('Build, publish, and verify a Deepline Play as a durable state machine over Customer DB tables, including a small paid pilot') and the 'when' with a concrete trigger phrase ('Invoke this skill explicitly when the user asks to build an engine'). Matches the anchor for clearly and explicitly answering both.

Trigger Term Quality

Natural phrases a user would say are present — 'build an engine', 'publish', 'verify', 'state machine', 'paid pilot'. Not 5 because common synonyms like 'orchestrator', 'workflow', or 'orchestrate' are missing; not 3 because keyword coverage is good, not partial.

Distinctiveness Conflict Risk

A clear niche with distinct triggers — 'Deepline Play', 'Customer DB tables', 'paid pilot' — that no generic skill would share, and the trigger ('asks to build an engine') is scoped to this domain. Minimal conflict risk.
