Conciseness

Dense and imperative throughout with no explanations of concepts Claude already knows, but contains minor duplication that could be trimmed: the 'support: one-source' rule appears in two separate rule bullets, and 'Preserve the source's own claim' overlaps 'Preserve the source's language'. This fits anchor 4 (efficient, minor instances of over-explanation) rather than 5, where every token earns its place with no repeated rules.

Actionability

Fully executable instruction-level guidance: exact file paths ('raw/YYYY-MM-DD-slug.md', 'wiki/sources/<slug>.md', 'wiki/questions/YYYY-MM-DD-<slug>.md'), a concrete citation format ('<repo>@<sha>:<path>:<line>'), specific commands ('git show <sha>:<path>', 'git status'), an exact commit message format ('kb(ingest): <source title>'), and explicit anti-patterns ('Never use git add .'). Per the rubric's scoring notes, absence of code in an instruction-only skill is not penalized when guidance is this actionable.

Workflow Clarity

Steps 0–10 are clearly sequenced with explicit validation checkpoints and feedback loops: inspect git status before editing, ask before combining uncommitted edits, report failed or truncated fetches rather than inventing archives, review the diff for secrets before committing, and an explicit failure path ('record that in log.md as left open — never leave it silent'). Validation is present, so the batch-operation cap does not apply.

Progressive Disclosure

No bundle files exist; the single body is well-organized into Boundaries / Protocol / Rules with clear section headers, so navigation is easy. However, at ~120 lines with three sub-procedures inlined in step 0 (URL handling, pinned code reads, and a full last-answer paragraph that is a candidate for its own reference file), it fits anchor 4 (good structure, minor organization gaps) rather than 5 — the under-50-lines exception does not apply.

Specificity

Lists multiple concrete actions — 'read it in full, compile durable cited pages, and update the index, log, and overview in one commit' — and enumerates all four accepted input types, giving comprehensive coverage of the operation. Anchor 4 would require minor gaps in coverage, but the read/compile/update/commit pipeline plus input handling is complete.

Completeness

Explicitly answers both what ('read it in full, compile durable cited pages, and update the index, log, and overview in one commit') and when ('Use when the user says ingest, compile this source, add this to the wiki, or pastes a link'), with concrete trigger phrases matching the top anchor exactly.

Trigger Term Quality

Provides four natural trigger phrases users would say: 'ingest, compile this source, add this to the wiki, or pastes a link to read into it'. Coverage is good but not comprehensive — common variations like 'archive this', 'save/remember this source', or 'knowledge base' are missing, so it sits between anchors 3 and 5, noticeably above the midpoint.

Distinctiveness Conflict Risk

Occupies a clear niche (wiki ingestion pipeline, integration with /kb-ask, wiki-specific triggers like 'add this to the wiki') with distinct trigger terms and minimal conflict risk against other skills.
