Conciseness

The body is efficient and assumes Claude's competence, listing hook triggers as concrete match rules rather than explaining what hooks or context windows are; a few sections restate the blocking-vs-non-blocking distinction and SOURCE provenance lines that could be trimmed slightly.

Actionability

It provides concrete, executable guidance — explicit extension lists, command match patterns, exit-code-2 blocking behavior, and pipeline exceptions — with only minor gaps (e.g. the exact hook script path or how additionalContext is formatted is not shown).

Workflow Clarity

The mermaid flowchart lays out a clear decision sequence, but the core operation (running hooks that block or warn on tool calls) has no explicit validation/verification checkpoints or error-recovery feedback loops; per the rubric, workflows involving batch/destructive enforcement without validation cap at 3.

Progressive Disclosure

Structure is good: an overview with well-signaled one-level-deep reference to ./references/investigation-escalation.md (which exists), and hook details kept inline rather than buried; minor gap is that some inline hook-behavior tables could live in a dedicated reference file.

Specificity

Names the domain (orchestrator context window discipline) and lists several concrete actions — 'Prevents the orchestrator from reading source files it will not edit, running diagnostic commands that waste context, and rationalizing delegation bypasses' and 'Activates PreToolUse hooks that surface decision points before source file reads and diagnostic command execution' — with only minor coverage gaps.

Completeness

It states both what it does (prevents specific wasteful orchestrator behaviors, activates PreToolUse hooks) and when to use it ('Use when setting up orchestrator guardrails, reviewing delegation discipline, or diagnosing context window waste'), though the 'when' trigger could be slightly more explicit about the most common natural scenario.

Trigger Term Quality

It includes some relevant phrases a user might say ('reviewing delegation discipline', 'diagnosing context window waste in multi-agent workflows'), but the natural trigger terms are specialized jargon (orchestrator, hooks, guardrails) rather than the everyday phrases a user would naturally utter, and synonyms/common variations are thin.

Distinctiveness Conflict Risk

The niche is clearly scoped to the orchestrator role and context-window discipline in multi-agent workflows, with distinct triggers unlikely to fire for unrelated skills; only minor overlap risk with general delegation or review skills.
