Conciseness

The body is dense, imperative, and free of padding — it never explains what GitHub or issues are, and every bullet states a skill-specific rule Claude could not infer. It sits at anchor 4 rather than 5 only because of minor repetition (the visible-summary/`<details>` rules are restated across the new-issue, edit-issue, and Quick Checks sections) and a few wordy phrasings that could be tightened.

Actionability

Concrete guidance throughout: exact paths (`.github/ISSUE_TEMPLATE/`), commands (`gh issue create`, `gh issue edit`, `/label <label name>`, `Suggested labels: ...`), concrete label names (`severity/major`, `severity/moderate`, `component/*`), and a concrete mechanism (`<details>` blocks). Anchor 5 is missed by minor gaps — no complete example invocations with flags (e.g. `gh issue edit --title ... --body-file ...`) and the duplicate-search step names no search command.

Workflow Clarity

The workflow has a clear numbered sequence (write → search → template → patch → label → file-based edits) with explicit validation checkpoints ("diff the patched body against the current issue body before calling gh", review against the template before calling gh), a genuine feedback loop for error recovery (label permissions missing → `/label` comment → `Suggested labels: ...` fallback), and a closing Quick Checks checklist — matching anchor 5's sequence + validation + feedback loop + checklist pattern.

Progressive Disclosure

There are no bundle files (references/, scripts/, assets/ are absent), and the ~50-line body needs none: it is cleanly organized into Overview, Workflow, and Quick Checks sections with no content that belongs in a separate file. Per the rubric's scoring note for short, single-purpose skills with no external references, this warrants a 5.

Specificity

The description lists several concrete actions — "Create or edit TiDB issues, choose labels, or check for duplicates before filing" — in a named domain (TiDB issue tracking). It stops short of anchor 5 because coverage has minor gaps: it never mentions applying issue templates or patching existing issue bodies, both of which are core parts of the skill's workflow.

Completeness

The "what" is clear (create/edit issues, choose labels, check duplicates), but there is no "Use when..." clause or equivalent explicit trigger guidance; "before filing" only weakly implies when to use the skill. Per the judging guidelines, a missing 'Use when' clause caps completeness at 3 — it is above anchor 2 because the "what" is concrete, but below anchor 4 which requires an explicit 'when'.

Trigger Term Quality

Natural terms users would say are present: "TiDB", "issues", "labels", "duplicates", "filing". It misses a few common variations such as "bug report", "GitHub issue", or "severity", so it fits anchor 4 (good coverage, a few natural terms missing) rather than the comprehensive synonym/extension coverage of anchor 5.

Distinctiveness Conflict Risk

"TiDB issues" carves out a clear niche with distinct triggers (TiDB, labels, duplicates), matching anchor 5's minimal conflict risk. It does not sit at anchor 4, since even a generic GitHub-issue skill would be distinguished by the TiDB qualifier and the metadata/label focus.
