Conciseness

Every element — category/severity label tables, assignee rules (@dr5hn, @copilot), response templates, and policy rules — is repo-specific knowledge Claude could not infer, with zero concept explanations or padding. Not 4: there is no over-explanation to trim; each table and template earns its tokens.

Actionability

The body provides exact labels (`data-correction`, `priority:high`), concrete category→label and severity tables, specific assignees, and copy-paste-ready response templates with links to the contribution guidelines and update tool. Not 4: guidance is fully executable for the common triage cases; as an instruction-only skill the absence of code is not penalized.

Workflow Clarity

A clear five-step sequence (classify → entity labels → severity → action → respond) with explicit guardrails ("Do not close issues without maintainer approval"), but no validation checkpoints such as checking for duplicate issues or confirming labels were applied. Not 5: no explicit validation/feedback steps exist; not 3: the sequence is complete and the operations (labeling, commenting) are low-risk, so the missing-validation cap does not apply.

Progressive Disclosure

The single-file body is well-organized with clearly headed sections and no buried references (none exist), but at ~95 lines the response templates are inlined content that could be split into a references file. Not 5: it exceeds the under-50-line simple-skill exception and inlines template content; not 3: structure is good, nothing is disorganized or nested.

Specificity

"Triage and classify new issues", "categorise, label, prioritise, or respond to a GitHub issue", and "deciding whether an issue can be auto-fixed or needs human intervention" list multiple concrete actions with comprehensive coverage of the triage domain. Not 4: there are no minor gaps — the actions span classification, labeling, prioritization, response, and auto-fix decisions.

Completeness

The description explicitly answers what ("Triage and classify new issues for the CSC database repository") and when ("Use this skill whenever an issue is opened, assigned to you, or needs classification. Trigger on: …") with concrete trigger phrases. Not 4: the when-clause is explicit and specific, not merely present.

Trigger Term Quality

Natural trigger phrases include "new issue triage", "'classify this issue'", "'what type of issue is this'", "labelling requests", and "data correction reports", covering synonyms and common user phrasings. Not 4: it includes quoted natural-language variations rather than missing a few common terms.

Distinctiveness Conflict Risk

The description is anchored to a specific repository and workflow ("CSC database repository", auto-fix vs. human intervention), but generic terms like "bug reports", "feature requests", and "issue assignment" carry minor overlap risk with general issue-management skills. Not 5: those generic trigger terms could fire for closely related issue-triage skills; not 3: the niche is clearly and consistently defined.
