Conciseness

The body is dense and procedural — exact files to read, classification rules, a scoring rubric, and a complete output template with no tutorials on concepts Claude already knows. Minor padding exists ("These are the most intellectually interesting outputs of the period", "think of it as a weekly review session", and a Notes section that restates guidance already embedded in steps), matching anchor 4 rather than anchor 5's every-token-earns-its-place standard.

Actionability

Fully executable guidance throughout: exact paths ("$OBSIDIAN_VAULT_PATH/log.md — last 200 lines"), a concrete period-parsing table, explicit link-interestingness scoring (+3/+2/+2/+1), a copy-ready markdown output template with frontmatter, exact bash commands (${QMD_CLI:-qmd} update/embed/ls), and an exact log-line format — a direct match for anchor 5.

Workflow Clarity

Steps 1-7 are clearly sequenced with explicit validation checkpoints and feedback loops: fewer than 5 active pages → offer to widen and stop, empty vault → stop, QMD failure → report separately without rollback, plus a six-row edge-case table covering missing optional files. The skill is read-only except two optional writes, so the destructive/batch validation cap does not apply.

Progressive Disclosure

No bundle files exist, so all 235 lines are inline in one file, but structure is good: scannable numbered sections, and cross-references to llm-wiki/SKILL.md sections are clearly signaled and one level deep. Not anchor 5 because a file this long never splits content into a references bundle (the output template and QMD boilerplate are candidates); not anchor 3 because nothing is buried and organization is genuinely strong.

Specificity

"Produce a day/week/month knowledge digest summarizing what was learned, updated, and connected in the wiki" names the domain and several concrete actions (summarize learned/updated/connected). It falls short of anchor 5 because it omits other concrete outputs the skill produces (emerging themes, notable connections, recommended re-reads), and exceeds anchor 3 because more than 1-2 specific actions are stated.

Completeness

Both parts are present: the "what" is explicit ("Produce a day/week/month knowledge digest summarizing what was learned, updated, and connected") and the "when" is an explicit "Use for" clause ("Use for readable recent-learning summaries"). Not anchor 5 because the when-clause lacks concrete trigger-phrase variations; not anchor 3 because trigger guidance is explicit rather than weakly implied.

Trigger Term Quality

Includes good natural keywords — "knowledge digest", "day/week/month", "wiki", "learned", "recent-learning summaries" — covering the main vocabulary a user would say. A few natural terms are missing, e.g. "what did I learn this week", "weekly review", "digest of my notes", which keeps it below anchor 5.

Distinctiveness Conflict Risk

"wiki-status reports source and ingestion state instead" explicitly disambiguates against the nearest competing skill, giving a clear niche (knowledge summaries vs. ingestion status) with distinct triggers and minimal conflict risk — a direct match for anchor 5.
