Conciseness

The body is dense and free of Claude-known concept padding, but the same key points are stated multiple times: "A verdict without a cited source is a guess, not a finding" appears in both the intro and Mindset sections, step 2's bullet "AVOID trusting a claim about this repository's own constraints... without reading the actual source first" is restated nearly verbatim in Anti-Patterns #2, and When to Use / When NOT to Use largely restate the frontmatter description the reader already has. This is more than the minor trimmable instances of anchor 4 and fits anchor 3's "could be tightened".

Actionability

The guidance is fully concrete and executable: a copy-paste validator invocation with exit-code semantics ("scripts/validate-tech-evaluation.sh <path-to-yaml>" with exit 0 / exit 1 meanings), the exact verdict enum, the exact scaffold path, a verbatim subagent instruction list, and a concrete BAD/GOOD YAML rationale example. As an instruction-only skill, this meets the copy-paste-ready anchor 5.

Workflow Clarity

The six-step workflow is clearly sequenced with an explicit validation checkpoint (step 3, with exit-code interpretation), a failure feedback loop ("send the YAML back to the subagent rather than manually patching it into shape"), and a completion confirmation ("confirm the new file is present in the regenerated index before reporting the evaluation as complete"). This matches the anchor-5 pattern of validate -> fix -> retry with checkpoints.

Progressive Disclosure

The body is a genuine overview: all five referenced bundle files (references/question-dimensions.md, references/finding-record-layout.md, assets/templates/tech-evaluation-scaffold.yaml, assets/schemas/tech-evaluation.schema.json, scripts/validate-tech-evaluation.sh) exist and are one level deep, clearly signaled both inline and in a dedicated References table with a When-to-Use column. Content is appropriately split with easy navigation.

Specificity

The description lists multiple concrete actions covering the full pipeline: "Investigate a candidate library, dependency, or file format against a fixed question set", "end with exactly one cited recommendation (adopt / keep_current / reject / needs_more_research)", and "Validates the structured output against a JSON schema before writing a human-readable finding". Coverage is comprehensive with no gaps, matching the anchor-5 example rather than the minor-gaps anchor 4.

Completeness

It explicitly answers both what (investigate against a fixed question set, validate against a JSON schema, write a human-readable finding, one cited recommendation) and when ("Use when choosing between candidate npm packages, dependencies, or file formats for a specific integration point, or when a plan or ADR decision hinges on an unverified factual claim"), with concrete trigger phrases. It also adds explicit negative triggers ("Do NOT use for one-line version lookups..."), which strengthens rather than weakens completeness.

Trigger Term Quality

It provides an explicit trigger list of natural phrases users would actually say ("evaluate this library", "investigate this dependency", "compare X vs Y", "which format should we use", "is this package maintained") plus concrete Use-when conditions mentioning npm packages, dependencies, file formats, and ADRs. This is comprehensive coverage including synonyms, exceeding the few-terms-missing anchor 4.

Distinctiveness Conflict Risk

The skill occupies a clear niche (evidence-cited technology evaluation with schema-validated output) with distinct triggers and explicit exclusions ("Do NOT use for one-line version lookups, purely subjective preference calls... or a technology choice already settled by an existing ADR"). Minimal conflict risk with adjacent research/comparison skills.
