Conciseness

The body is ~700 lines of dense implementation spec — prior-search credit stem matching, exclusion parsing for rg/grep/fd/tree/git, 8.3 short names, ADS-style path handling, hard-link realpathing — that is hook-internal behavior, not guidance the agent needs at invocation time. Anchor 2 ("noticeably verbose; several unnecessary explanations or padded sections") fits: it is not explaining things Claude already knows, but much of it is edge-case enumeration that could be trimmed or moved to reference files, which is below the mostly-efficient anchor 3.

Actionability

Quick Start gives two concrete install paths ("pip install gateguard-ai\ngateguard init", enabling scripts/hooks/gateguard-fact-force.js via hooks.json), a full env-var table with defaults, an executable metrics report command, and a copy-paste JSON env example. Minor gaps keep it below 5: Option A never shows the actual hooks.json snippet to enable the hook, and no command verifies the hook is active.

Workflow Clarity

The operative sequence exists (enable hook → set env vars → handle first-touch denials by presenting facts and retrying, with the parallel-batch warnings), but there is no checkpoint verifying the gate is installed and firing before relying on it, and the installation steps are buried under ~500 lines of gate-behavior spec that precedes Quick Start. A destructive/batch-adjacent tool skill without an explicit validation step cannot exceed 3.

Progressive Disclosure

No references/, scripts/, or assets/ directories exist in the bundle, yet the body cites scripts/hooks/gateguard-fact-force.js, scripts/gateguard-report.js, and docs/gateguard/change-profile.md as if present — key navigation targets are dangling. Meanwhile ~400 lines of matching-rule spec (prior-search credit, comment-only edits, sibling collapse) that clearly belongs in separate reference files are inlined in SKILL.md, matching anchor 2.

Specificity

The description lists multiple concrete actions with comprehensive coverage: "denies the first Edit/Write/Bash (including MultiEdit and NotebookEdit) attempt until the agent presents concrete facts (importers, data schemas, verbatim user instruction), then allows retry" — each gate behavior is named specifically, including tool variants and the retry mechanism.

Completeness

It explicitly answers both what the skill does (three-stage deny/force/allow fact-forcing gate with named facts) and when to use it ("Use when enabling or configuring the GateGuard hook, exempting paths via env vars, or handling first-touch denials"), with concrete trigger phrases.

Trigger Term Quality

Trigger phrases like "enabling or configuring the GateGuard hook", "exempting paths via env vars", and "handling first-touch denials" are natural for this skill's audience, and tool names (Edit/Write/Bash, MultiEdit, NotebookEdit) match what users would say. A few plainer synonyms (e.g., "block edits", "hook keeps asking me to list importers") are missing, so it sits between the good and comprehensive anchors — noticeably above the midpoint.

Distinctiveness Conflict Risk

The GateGuard/fact-forcing niche is highly specific — a PreToolUse hook that denies first edit attempts and demands importers/data schemas — and it positions itself against neighbors ("No competitor does all three"), so the risk of triggering for the wrong skill is minimal.
