Conciseness

The body is dense and operational — commands, contracts, and output templates with almost no generic explanation Claude already knows. But the multi-paragraph "Open with" good/bad tutorial (including the explanation of why the good version is good) and the 15-item Gotchas list contain minor padding that could be trimmed, matching anchor 4 rather than the lean anchor 5.

Actionability

Every phase has copy-paste-ready commands (minutes person/search/get with exact flags, calendar fallbacks including a concrete osascript snippet), an exact output template for the brief, precise slug/permission rules (chmod 700/600, YYYY-MM-DD-first-name.brief.md), and an exact closing line. Fully executable guidance covering the common cases — anchor 5.

Workflow Clarity

Phases 0–5 are clearly sequenced with explicit validation checkpoints and failure feedback loops: "Require exit status 0", "Never suppress a nonzero exit", verify via live-source search before declaring "first meeting on record", "If none return anything, ask once", and silent-exit behavior for hook mode. Matches anchor 5's sequence + checkpoints + error-recovery pattern.

Progressive Disclosure

The 205-line body is well-sectioned into phases, but everything is inline in a single file with no reference split at all — the extended Open-with tutorial, the detailed slug rules, and the long Gotchas list are candidates for a one-level-deep reference file. This matches anchor 3 (some structure, content that should be separate is inline) rather than 4, since no appropriately-split reference material exists.

Specificity

The description lists multiple concrete actions — "auto-detects your next calendar event, pulls relationship history, surfaces open commitments, and produces a one-page brief in under 30 seconds" — with comprehensive coverage of what the skill does, matching the anchor-5 example. It is not a 4 because there are no gaps in the capability enumeration; every core function is named with a concrete verb.

Completeness

Explicitly answers "what" (first sentence of concrete capabilities) and "when" ("Use this whenever the user says...") with concrete trigger phrases, plus a when-not-to clause ("use prep when the user wants to think hard about goals first"). Matches anchor 5 exactly; the 'Use when' cap of 3 clearly does not apply.

Trigger Term Quality

Nine quoted natural trigger phrases ("brief me", "give me a quick brief", "what's coming up", "background on my next call", "who am I meeting next", "brief me on Sarah", "I have a call in 10 min", "quick rundown", "right before walking into a meeting") cover synonyms, name-argument variants, and urgency variants a user would actually say. Matches anchor 5's comprehensive natural-term coverage.

Distinctiveness Conflict Risk

"Different from /minutes-prep — brief is the fast hook-fireable version that doesn't ask questions and doesn't set goals" plus "Use brief when speed matters; use prep when..." explicitly disambiguates from the only sibling skill. Clear niche with distinct triggers and minimal conflict risk; not a 4 because the one close neighbor is already explicitly fenced off.
