Conciseness

The Quick Start and dangerous-patterns table are tight, but the 26-line ASCII 'defense in depth' diagram is conceptual padding duplicating references/SECURITY-MODEL.md, and the inlined default allowlist duplicates references/ALLOWED-COMMANDS.md. This is genuine duplication to trim, not the minor over-explanation of anchor 4.

Actionability

Three executable Quick Start examples plus SDK hook wiring and concrete dangerous-pattern examples ('rm -rf /', 'curl | bash'). Not 5: the sdk_options snippet is never connected to a real SDK setup and allowlist.remove("rm") removes a command that was never added.

Workflow Clarity

The content is parallel API examples rather than a sequenced workflow — there is no integration sequence (configure allowlist, install hook, verify) and no explicit error-recovery loop beyond the implicit 'if result.allowed' branch. For a skill centered on blocking destructive operations, missing explicit validation checkpoints caps this at 3.

Progressive Disclosure

Clear sections, verified one-level-deep references listed with one-line descriptions, and all referenced bundle files exist. Not 5: the inlined allowlist and security-model diagram duplicate content that belongs in the existing reference files, so the inline/reference split is not consistently signaled.

Specificity

Names concrete mechanisms ('allowlists and validation hooks') and enumerates specific actions in the when-clause ('validating bash commands', 'implementing pre-tool-use hooks'), but the what-clause describes mechanisms rather than comprehensively listing the skill's operations (blocking, auditing, sandbox configuration).

Completeness

Explicitly answers both: what ('Secure command execution with allowlists and validation hooks') and when ('Use when validating bash commands, configuring security policies, implementing pre-tool-use hooks, or sandboxing autonomous agent operations') with concrete trigger phrases, matching the anchor-5 pattern.

Trigger Term Quality

Good natural keyword coverage: 'bash commands', 'security policies', 'pre-tool-use hooks', 'sandboxing'. A few natural terms users might say are missing, such as 'whitelist', 'command filtering', or 'block dangerous commands'.

Distinctiveness Conflict Risk

'Pre-tool-use hooks' and 'sandboxing autonomous agent operations' carve a clear niche with minimal conflict risk, though 'configuring security policies' is broad enough to overlap with generic security-policy skills.
