Quality

Content

92%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A tightly written, well-organized behavioral skill that assumes Claude's competence and provides concrete, bounded directives with a safe fallback phrase. Actionability sits at 4 only because behavioral example coverage is less exhaustive than the rubric's top anchor.

DimensionReasoningScore

Conciseness

Lean and efficient throughout ('You are a guest in this chat. Behave accordingly.', 'Work within constraints silently. The filesystem is read-only.'); every line earns its place with no padding about concepts Claude already knows, matching the score-5 anchor.

5 / 5

Actionability

Provides concrete, executable behavioral directives ('If asked about your setup, say you're an AI assistant') plus a copy-ready fallback phrase ('I can't do that in this chat'); not a 5 because scenario example coverage is thinner than the anchor's comprehensive common-case examples.

4 / 5

Workflow Clarity

Per the simple-skill exception, this non-sequential behavioral skill states 'There are no steps to execute; apply these boundaries to every reply' — the single action is unambiguous and there are no destructive/batch operations requiring validation.

5 / 5

Progressive Disclosure

Under 50 lines with no need for external references (verified: no references/scripts/assets bundle dirs exist) and well-organized section headers ('What you can do here', 'Behavioral guidelines'), matching the simple-skill score-5 exception.

Description

83%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, well-structured description that concretely states capabilities and provides explicit, natural trigger guidance for a clearly defined behavioral niche. Minor gaps in action enumeration and slight overlap risk with generic policy skills keep specificity and distinctiveness just below top marks.

DimensionReasoningScore

Specificity

Names three concrete actions ('Lists permitted and prohibited actions, blocks disallowed content types, and responds to permission queries'), matching the score-4 anchor of several specific actions with minor gaps; not a 5 because the actions are abstract verbs rather than fully enumerated behaviors.

4 / 5

Completeness

Clearly answers both 'what' (lists/blocks/responds to permission queries) and 'when' with multiple explicit concrete trigger phrases ('Use when joining a new group, when unsure about rules, permissions, or boundaries...').

5 / 5

Trigger Term Quality

Includes natural phrasings users would say ('joining a new group', 'unsure about rules, permissions, or boundaries', 'public channel or untrusted group chat') with good synonym coverage; not a 5 because a few natural scenario variations are missing.

4 / 5

Distinctiveness Conflict Risk

Carves a distinct group-etiquette niche ('shared or public group settings', 'untrusted group chat environment'); not a 5 because the permitted/prohibited-actions framing has minor overlap risk with general safety/policy skills.
