Conciseness

The body is lean and assumes Claude's competence — no concept tutorials, no filler — with every section carrying functional weight (pipeline diagram, inputs, output template, workflow, routing). Minor instances remain that could be trimmed, e.g. the 'Why This Step Exists' rationale paragraph and the 'Version: 1.0.0' footer, so it fits 'efficient; minor instances of over-explanation' rather than the every-token-earns-its-place anchor at 5.

Actionability

Gives concrete, executable guidance: the exact output path ('~/.claude/briefs/YYYY-MM-DD-<slug>.md'), a complete fill-in markdown template, and an 8-step numbered workflow. It falls short of fully copy-paste-ready because some steps are underspecified — 'prompt the founder for the missing pieces' does not say which pieces or how to ask — placing it at 'mostly executable; concrete with minor gaps' rather than 5.

Workflow Clarity

The workflow has a clear 8-step sequence with explicit ordering constraints ('Write success + kill criteria BEFORE the decision (this is the rigor moment)') and well-defined inputs for each branch (office-hours output vs. raw topic). Checkpoint-style validation of the drafted brief (e.g. re-checking it against the intake answers) is only implicit, which keeps it below the explicit-validation anchor at 5; the steps are far too complete and sequenced for a 3.

Progressive Disclosure

Sections are well-organized and the related-skill/agent links ('context-engine', 'board-meeting', 'cs-chief-of-staff') are one level deep and clearly signaled. No bundle files exist, but the ~118-line body inlines the full output template and the 15-item role checklist that could partially live in a reference file — good structure with minor organization gaps, matching the 4 anchor rather than the ideal split at 5.

Specificity

Names several concrete actions — 'Generate a one-page strategy brief from an office-hours intake', 'locking options, assumptions, and success criteria' — with minor coverage gaps (e.g. saving/routing behavior is not mentioned). It lists more than 1-2 actions but is not a comprehensive capability inventory, so it fits the 'several specific actions; minor gaps' anchor rather than 3 or 5.

Completeness

Explicitly answers both what ('Generate a one-page strategy brief from an office-hours intake') and when ('Use when a strategic question needs to be framed before boardroom deliberation — e.g. locking options, assumptions, and success criteria for a pricing change or a market-entry decision') with concrete trigger phrases and examples. This matches the top anchor exactly; neither what nor when is vague or implicit.

Trigger Term Quality

'strategy brief', 'strategic question', 'pricing change', 'market-entry decision', and 'boardroom' are phrases users would naturally say when needing this skill. Common synonyms like 'one-pager', 'decision memo', or 'planning doc' are missing, which keeps it below the comprehensive-synonyms anchor at 5.

Distinctiveness Conflict Risk

The '/cs:brief' pipeline position and terms like 'office-hours intake' and 'boardroom deliberation' give it a clear niche with distinct triggers. Phrases like 'strategic question needs to be framed' could mildly overlap with generic planning/strategy skills, so it sits at 'mostly distinct; minor overlap risk' rather than the minimal-conflict anchor at 5.
