Conciseness

The body is overwhelmingly lean imperative instruction — exact templates, commands, and formats — with only minor over-explanation: the scaffold step 2 justification paragraph ("Measured 2026-08-22 over three save-new runs — the asset is 214 lines and none of the three copied it: two wrote their own 57-line schema...") is dated evidence narrative that could be trimmed to its operative rule, and motivational asides like "without it, the memex does not compound". Not 5: those few sentences don't earn their place; not 3: they are confined to one paragraph, and the rest assumes Claude's competence without padding.

Actionability

Fully executable guidance throughout: the exact WebFetch prompt ("Extract the complete article content. Return: title, author(s)..."), copy-paste grep command (grep -rln "<new page title>" <memex-root>/pages/), exact frontmatter and index/log templates, precise slug rules (lowercase, strip non-[a-z0-9-], truncate 60, date prefix, -2/-3 collision handling), and explicit CREATE/UPDATE decision criteria for entities. Not 4: no gaps — the common cases (URL, file, free text) each have concrete handling.

Workflow Clarity

A clearly sequenced 10-step workflow with explicit validation and feedback loops despite the batch nature (5–15 pages per source): step 7 is a marked "CRITICAL — do not skip" backlink audit with a validate-then-fix loop (grep for mentions, add missing SALP REFs at first natural mention), WebFetch failure has a retry-once-then-stop loop, and Error Handling enumerates five failure modes with recovery actions (recreate missing index.md, create missing raw/articles/). The contradiction-handling section adds a checkpoint requiring both pages be touched. Not 4: checkpoints are not merely 'mostly present' — the audit, retry, and error-recovery loops are explicit, so the batch-operation cap at 3 does not apply.

Progressive Disclosure

Structure is appropriate: the 175-line body carries only the workflow, while the schema/templates/anchor grammar live in the referenced assets/AGENTS.md — a real, verified bundle file referenced one level deep and clearly signaled ("Copy the schema asset file... Locate it at assets/AGENTS.md"); the short index/log scaffold templates are correctly inlined as single-use content. Not 4: the split is clean and navigation is easy, with no content that belongs in a separate file inlined beyond the minimal SALP notation note needed for inline correctness.

Specificity

The description lists four concrete actions — "Stores the raw source", "extracts cross-linked entity pages", "audits backlinks", "updates the index" — which comprehensively covers the save pipeline at the description level, matching the anchor-5 pattern of multiple specific actions with comprehensive coverage. Not 4: unlike 'minor gaps in coverage', the store/extract/audit/index chain covers the whole workflow; the omitted log-append is a sub-step, not a capability gap.

Completeness

It explicitly answers both parts: what ("Stores the raw source, extracts cross-linked entity pages, audits backlinks, updates the index") and when ("Use when the user gives a source (URL, file, or text) to save into the project's memex"), with concrete trigger phrasing plus a negative boundary ("Not for casual reads"). Not 4: the 'when' clause is fully explicit with enumerated source types, not merely present-but-improvable.

Trigger Term Quality

Good natural-term coverage: "save", "source", "URL, file, or text", "memex", "knowledge bank" — phrases a user of this project would naturally say ("save this URL"). Not 5: common synonyms like "add", "store", or "capture" are absent, so it falls at 'good keyword coverage; a few natural terms missing' rather than comprehensive synonym coverage.

Distinctiveness Conflict Risk

"memex" is a distinct project-specific niche term, so the description is unlikely to fire for unrelated skills, and "Not for casual reads" adds an explicit boundary against mis-triggering on generic read/browse requests. Not 4: there is no meaningful overlap with a neighboring skill's triggers — the domain term alone disambiguates.
