Conciseness

Every sentence delivers plugin-specific information Claude cannot know (OAuth architecture, the skill routing map, tool constraints, spend-approval guardrails) with zero padding and no explanation of known concepts. This matches the lean anchor where every token earns its place; the nearest lower anchor (4) requires trimmable over-explanation, which is absent.

Actionability

Concrete, executable routing ("Use **report** and **attribution** to review performance, **media-plan** and **launch** to prepare approved campaign changes") and specific guardrails ("obtain explicit approval for spend-changing actions") with pointers to real files. It falls short of fully copy-paste-ready anchor 5 because "verify provider readback" and the MCP tool usage are stated as policies without an example invocation.

Workflow Clarity

This is a simple single-purpose router skill under 50 lines whose single action is unambiguous: each user intent maps to a named skill. It even includes explicit checkpoints (read brand-and-safety guidance before copy or spend, obtain approval, verify provider readback before claiming completion), satisfying the simple-skill exception for a top score.

Progressive Disclosure

The body is a pure overview that delegates detail to well-signaled, one-level-deep references — "[brand and safety guidance](../../context/brand-and-safety.md)" with its purpose stated, the bundled tool directory, and eight named sibling skills — with no nested reference chains. This matches the clear-overview anchor 5 rather than anchor 4, which requires organization gaps.

Specificity

The description names its domain and topics concretely ("bundled skills, supported MCP tools, OAuth setup, and support options") but relies on a single generic action verb ("Explain") and never says what the plugin actually does. This matches the anchor for a named domain with 1-2 concrete actions that is not comprehensive, not the level above which requires several specific actions.

Completeness

The "what" is clear (explains the bundle's skills, MCP tools, OAuth setup, support), but there is no "Use when..." clause or equivalent trigger guidance, capping completeness at 3 per the judging guidelines. It is not a 2 because the "what" is specific rather than vague.

Trigger Term Quality

"OAuth" and "support" are terms a user would naturally say, and "MCP tools" is semi-natural, but common variations like "help", "sign in", "connect", or "what can this plugin do" are missing. Some relevant keywords with missing synonyms fits anchor 3, below the good-coverage anchor 4.

Distinctiveness Conflict Risk

"OAuth setup" and "bundled skills" anchor it to this specific plugin, but a generic explain/help description could overlap with other help or onboarding skills. Somewhat specific with residual overlap risk matches anchor 3 rather than the mostly-distinct anchor 4.
