Conciseness

The body is efficient: a dispatch table, exact fallback prompts, and pointed references, with essentially no explanation of concepts Claude already knows. It could still be trimmed — the three bash 'Usage Examples' blocks are illustrative comments rather than instructions, and each Anti-Pattern carries a "Why:" rationale that is somewhat padded. Not 5 because of those padded sections; not 3 because nothing here is redundant teaching, and the AskUserQuestion guard is genuinely novel operational knowledge.

Actionability

Concrete, executable guidance throughout: a dispatch table mapping each subcommand to a specific protocol file ("Read references/protocols/anchor.md → execute"), an exact AskUserQuestion prompt with enumerated options A-D, explicit sub-agent spawn instructions, and a 4-element structured output format. Not 5 because the `deep` sub-agent prompt is only sketched ("target description + relevant file paths") rather than given as a ready-to-use prompt, and the 'Usage Examples' are commentary rather than runnable invocations.

Workflow Clarity

Sequencing is clear: parse subcommand → dispatch table → execute protocol; no-subcommand fallback routes through an explicit question; and the AskUserQuestion guard is a genuine validation checkpoint with error recovery (empty answers → numbered text list → wait for reply). Not 5 because the "Wait for user reply" loop has no timeout/escalation path and per-subcommand execution details are deferred to referenced files without an explicit completion check in the body.

Progressive Disclosure

Good structure: the body stays an overview (dispatch, guard, output format pointer) while pattern catalogs and protocol steps live in four real, one-level-deep reference files, all listed with content descriptions in the References section (all verified to exist). Not 5 due to minor organization gaps: the body's 'When to Use' section substantially duplicates reference.md's When-To-Use Guide, and the body states "9 patterns" while reference.md's header reads "v1: 8 patterns" (its table actually lists 9), a small cross-file inconsistency.

Specificity

Top-level actions ("Challenge, push back, play devil's advocate on AI output") are near-synonyms rather than distinct capabilities, but the subcommand list ("anchor (committed too fast), verify (facts wrong?), framing (wrong problem?), deep") enumerates four concrete, distinct functions. Not 5 because the headline verbs overlap instead of covering comprehensively distinct actions; not 3 because the subcommand breakdown clearly exceeds 1-2 concrete actions.

Completeness

Both questions are explicitly answered: "what" via "Challenge, push back, play devil's advocate on AI output" and "when" via the explicit "Use when:" clause with concrete trigger phrases. This matches the anchor 5 example's structure (action list + explicit trigger phrases) and the subcommand list further enriches the 'what'.

Trigger Term Quality

The "Use when" clause provides comprehensive natural phrasing users would actually say: "challenge this, are you sure, push back, prove it, what if you're wrong, devil's advocate, stress test, poke holes, second opinion, sanity check, too confident, really?, question this decision". These are synonyms and colloquial variations, matching the top anchor exactly.

Distinctiveness Conflict Risk

The niche (adversarial challenge of AI output) is distinct with dedicated triggers like "devil's advocate" and "poke holes". However, broadly applicable phrases such as "second opinion", "sanity check", "prove it", and "stress test" could also plausibly trigger verification or code-review skills, creating minor overlap risk. Not 5 because of that overlap; not 3 because the core triggers are unmistakably about challenging/pushing back.
