Conciseness

The ~40-line body is lean and assumes Claude's competence: terse policy statements ("never rewrite a `user` requirement to make a design pass — ask that single item instead"), no explanations of known concepts, and JSON blocks only where the exact file schema cannot be guessed. Every token earns its place, matching anchor 5 rather than the minor-trimming-needed anchor 4.

Actionability

Fully executable instruction guidance: copy-paste-ready JSON templates for requirements.json and contract.json, the exact source enum ("user / default / research"), a named tool (AskQuestion) with concrete batching rules ("one batch, specific items only, each with 2-4 concrete options"), and an explicit write-back rule. Per the code-vs-instruction note, absence of code is not penalized since the guidance is this concrete.

Workflow Clarity

Six numbered steps in clear sequence with an explicit validation gate ("PRD is ready when `open_questions` is empty"), a feedback loop (open items → AskQuestion → write back with source "user" → empty the list), and an explicit stop-and-handoff rule. This is a drafting workflow, not a destructive or batch operation, so the validation cap does not apply, and it matches the anchor-5 pattern of explicit checkpoints with error-recovery guidance (the never-rewrite-user-requirements guard).

Progressive Disclosure

The pointer to the field contracts is clearly signaled and one level deep, but it targets "<repo>/reference/replicator-original/product/requirements-contract/references/product-files.md" — a placeholder path outside the skill bundle, and no references/ directory exists in the bundle, so the deferred content is unreachable from SKILL.md alone. Since the skill genuinely needs this reference, the under-50-lines exception does not apply, and broken reachability is more than the minor organization gap of anchor 4.

Specificity

"Write or revise hardware product requirements (product/README.md, product/requirements.json, product/contract.json)" names the domain, two concrete actions, and three specific output files, matching the several-specific-actions-with-minor-gaps anchor. It falls short of anchor 5 because it never indicates what requirement domains are covered (e.g., battery life, connectivity, enclosure), so coverage is not comprehensive.

Completeness

The what is explicit ("Write or revise hardware product requirements (product/README.md, product/requirements.json, product/contract.json)") and the when is an equally explicit trigger clause ("Use at the start of any hardware product design before parts selection"), matching the anchor-5 example structure of both answers with concrete trigger phrases.

Trigger Term Quality

Natural phrases like "hardware product requirements", "hardware product design", and "parts selection" give good keyword coverage, matching anchor 4. It misses common synonyms a user would say — "PRD", "product spec", "specification" — so it does not reach anchor 5's comprehensive synonym coverage.

Distinctiveness Conflict Risk

The "hardware" qualifier plus the pipeline position "before parts selection" carve out a clear niche with distinct triggers, minimal conflict risk against software-PRD, general-writing, or parts-selection skills. Matches the clear-niche anchor rather than the minor-overlap anchor 4.
