Conciseness

The body is dense procedural policy that assumes Claude's competence and never explains what PCB/CAD/Gerbers are; a few long layered sentences keep it just short of fully lean.

Actionability

It gives concrete executable guidance — exact tool calls (pcb.run, cad.export, cad.print.prepare), exact file paths, and exact skills to load — with only minor gaps typical of an instruction-only orchestrator.

Workflow Clarity

A clear numbered read order and explicit phase-gating with validation checkpoints (empty open_questions, blocked-section reporting, release-before-ending) is present, but some error-recovery feedback loops are implicit rather than spelled out.

Progressive Disclosure

The body is an overview pointing to three real one-level-deep reference files (operating-model.md, product-hardware-cad-workflow.md, pcb-workflow.md), clearly signaled in the read order; references are path-based rather than markdown links, a minor gap.

Specificity

The phrase 'Use before Project Replicator product, hardware, PCB, CAD, manufacturing, or review work' names the domain broadly but describes no concrete capability — the only action is 'Use before', so it lands at 'names the domain but actions are minimal or generic'.

Completeness

It gives a clear 'when' ('Use before ... work') but omits the 'what' — the description never states what the skill does, matching the 'only when is present without what' anchor.

Trigger Term Quality

'product, hardware, PCB, CAD, manufacturing, or review' are natural terms users would say, giving good keyword coverage, though some common synonyms/variations are missing.

Distinctiveness Conflict Risk

The 'Project Replicator' proper noun and PCB/CAD narrowing add specificity, but the broad enumeration of overlapping domains keeps real conflict risk with sibling replicator skills.
