Conciseness

The body is mostly operational with useful cost rationale ("Reading is the dominant cost of this skill", "This usually returns 15–30 lines per hit instead of 100–500"), but contains a few trimmable asides like "This preserves existing behavior — nothing changes unless the user asks for it" and "this is the expensive path and they should know". It is not a 5 because of these minor over-explanations, and not a 3 because nearly all content is actionable instruction rather than concept explanation.

Actionability

Guidance is concrete and near copy-paste ready: specific paths ("Read `~/.obsidian-wiki/config` to get `OBSIDIAN_VAULT_PATH`"), a concrete grep pattern ("`^(title|tags|aliases|summary):`"), an executable command ("`Grep -A 10 -B 2 "<query-term>" <candidate-file>`"), a full QMD invocation block, and templates for the log line and answer format. Not a 4 because the specific commands, file paths, and templates cover the common cases end to end.

Workflow Clarity

Steps 1–6 are clearly sequenced with explicit escalation conditions and guards ("only if Steps 2/2b are inconclusive", "GUARD: If `$QMD_WIKI_COLLECTION` is empty or unset, skip this entire step", "If you're still short, **then** fall back to a broad content grep") and conditional exits at every tier. It is not a 5 because there is no explicit verification checkpoint on the output (e.g., confirming cited `[[page]]` names actually exist), and not a 3 because decision points and fallbacks are explicit at each step.

Progressive Disclosure

Sections are well organized (Before You Start, Visibility Filter, Retrieval Protocol, Answer Format) and references are one level deep and clearly signaled ("Follow the Retrieval Primitives table in `llm-wiki/SKILL.md`", "See `.env.example` for setup"). It is not a 5 because the body depends on `llm-wiki/SKILL.md` and `.env.example`, neither of which exists in this skill's bundle (no references/, scripts/, or assets/ directories are present), and not a 3 because structure and reference signaling are otherwise good and the inline protocol content is appropriately placed.

Specificity

Multiple specific concrete actions are listed with comprehensive coverage: "Answer questions by searching the compiled Obsidian wiki", "find information across their wiki", "synthesized answers with citations", "explore connections between topics", and the index-only mode that "returns answers from page summaries and frontmatter without reading page bodies". Not a 4 because the action list covers the skill's full capability set, including the fast mode, with no notable gaps.

Completeness

Both what and when are answered explicitly: the what in "Answer questions by searching the compiled Obsidian wiki" (with capability details) and the when in "Use this skill when the user asks a question about their knowledge base..." followed by multiple concrete trigger phrases. Not a 4 because the when-clause is explicit and enumerates specific triggers rather than leaving timing implicit.

Trigger Term Quality

Comprehensive natural-language triggers including synonyms and quoted phrases users would actually say: "knowledge base", "wiki", "what do I know about X", "find everything related to Y", plus fast-mode triggers "quick answer", "just scan", "don't read the pages", "fast lookup". Not a 4 because it goes beyond good keyword coverage to explicit quoted user phrasings for both normal and fast modes.

Distinctiveness Conflict Risk

The skill occupies a clear niche — a compiled personal Obsidian wiki — with triggers keyed to it ("knowledge base", "their wiki", "wiki pages") that would not naturally invoke unrelated skills. Not a 4 because the trigger vocabulary is domain-specific enough that overlap risk with generic search or document skills is minimal.
