Conciseness

Efficient and assumes Claude's competence ('Use `rg` to find real usage before defining or renaming a term'; 'Glossaries are usually short enough to load entirely'), but there is minor redundancy: 'Before any edits, read the existing glossary' in Workflow Notes restates the 'Discover the Local Convention' section, and the section-audience guidance slightly overlaps 'Where a Term Goes'. Fits the 4 anchor (minor trimming possible) rather than the 5 anchor's every-token-earns-its-place.

Actionability

Concrete, executable guidance throughout for an instruction-only skill: a copy-paste entry-format template ('**Term** - One-line definition. Link to...'), concrete cross-link examples ('[ADR-005](adr/ADR-005-example.md)', '`src/example.ts`'), a specific command ('Use `rg`...'), and fully specified numbered steps per mode. Nothing is vague or pseudocode-like; fits the 5 anchor.

Workflow Clarity

Three modes with clearly sequenced numbered steps and real checkpoints: 'Confirm the term or a near-duplicate does not already exist', 'If the definition, canonical name, or placement is ambiguous, propose the wording first and ask the user to choose', and propose-only audits ('Keep audits propose-only unless the user explicitly asks'). Fits the 4 anchor due to a minor validation gap — no explicit verification step after applying an edit (e.g. re-checking placement or link validity post-edit) — so it does not reach the 5 anchor's explicit feedback loops.

Progressive Disclosure

A single self-contained file with a clear section hierarchy (what it is/is not, conventions, placement, ordering, format, three run modes, heuristics, notes) and no bundle files. Nothing that belongs in a separate file is inlined, there is no nesting, and navigation is easy — fitting the 5 anchor via the simple-skill exception for well-organized self-contained content.

Specificity

Names the domain ('project's glossary of domain terms, usually in docs/GLOSSARY.md') and lists multiple concrete actions: 'looking up terms, adding or updating definitions, renaming concepts, or auditing... for missing, stale, duplicated, or misplaced entries'. Coverage spans all of the skill's modes comprehensively, matching the top anchor rather than the 'minor gaps' anchor below.

Completeness

Explicitly answers 'what' ('Maintain a project's glossary of domain terms, usually in docs/GLOSSARY.md') and 'when' ('Use when looking up terms, adding or updating definitions, renaming concepts, or auditing a glossary...') with concrete trigger phrases. This matches the 5 anchor exactly; the 4 anchor's weaker 'when' does not apply.

Trigger Term Quality

Natural keywords like 'looking up terms', 'adding or updating definitions', 'renaming concepts', and 'GLOSSARY.md' are present and would be said by users, but a few natural synonyms are missing ('define a term', 'jargon', 'vocabulary', 'what does X mean'). Falls between the 4 anchor ('good keyword coverage; a few natural terms missing') and the 5 anchor's comprehensive synonym coverage.

Distinctiveness Conflict Risk

Clear niche (glossary maintenance) with distinct triggers (term lookup, definition updates, renaming, auditing against docs/code/decision records). Minimal overlap with other documentation skills; matches the 5 anchor ('clear niche with distinct triggers; minimal conflict risk').
