Dense and fluff-free with no explanation of concepts Claude already knows — every section is operational (file map, wiring table, gotchas, verification recipe). Not a 2 because there is no unnecessary explanation to tighten; the volume reflects the genuine 10-agent scope rather than padding.

Provides exact file paths, copy-paste JSON hook entries, concrete shell test commands, and a direct script probe. The /ABSOLUTE/HOME/ placeholder is explicitly justified ("Use absolute paths in configs"), so it stays copy-paste ready. Not a 2 because the guidance is fully executable, not pseudocode.

The "Add or tune a pattern" section is a clear numbered sequence with explicit validation checkpoints ("Must pass 100%", the python compile check, test-guard.sh ending "failed: 0") and an E2E verification recipe. Not a 2 because validation and feedback steps are explicit; the destructive-operation cap does not apply since verification is present.

No bundle files exist (references/, scripts/, assets/ are absent) and the 95-line body is a monolith with substantial inline content (the per-agent wiring table and the gotchas list) that could be split into reference files. Not a 3 because there are no signaled one-level-deep bundle references; not a 1 because sections are well-organized, not a nested wall of text.

Names multiple concrete actions — "adding or tuning blocked-command patterns, wiring the guard into a new agent or a new machine, debugging why a command was (or was not) blocked" — plus an explicit command denylist (rm -rf, dd/mkfs, curl|sh, git push --force). Matches the anchor listing multiple specific concrete actions; not a 2 because it is comprehensive rather than partial.

Explicitly answers what ("One shared denylist of catastrophic shell commands ... enforced as a PreToolUse/pre-exec guard") and when via an explicit "Use when ..." clause with concrete triggers. Matches the anchor requiring both what and when; not a 2 because the when clause is explicit, not merely implied.

Includes natural phrasings a user would say — "command guard, guardrails, dangerous command hook, or PreToolUse safety" — covering common variations. Not a 2 because it spans several natural synonyms rather than a single keyword.

A clear niche (cross-agent catastrophic-command guardrails) with distinct triggers unlikely to overlap with other skills. Not a 2 because the scope and trigger terms are specific enough to avoid collisions.
