Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description fully discloses behavioral traits: authentication needed (HTTP 401 otherwise), metered charge ($0.001–$0.25), royalty logging. It does not mention rate limits or idempotency, but for a read-like operation this is acceptable. No contradiction with annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single paragraph that efficiently covers purpose, usage, auth, cost, and return value. It is front-loaded with the main action. However, it could be slightly more structured (e.g., bullet points) for quick scanning. No wasted sentences.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no output schema, the description adequately explains the return value ('full content payload with provenance metadata'). It covers auth, cost, parameter details, and usage boundaries. Lacks explicit mention of error cases beyond 401, but the tool is simple and the description is fairly complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with both parameters described in the schema. The description adds only redundant detail for pocket_id and query. It provides context about the hex format but does not significantly add meaning beyond the schema. Baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action: 'Pull licensed creator content from a specific pocket by ID.' It distinguishes from sibling tools by explicitly saying 'Do NOT use for browsing or discovery — use search_pockets or list_pockets instead.' This provides a specific verb+resource and differentiates from alternatives.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives explicit when-to-use context: 'retrieve verified, provenance-tracked content for generation, RAG, or training purposes.' It also states when not to use and provides alternative tools. Auth requirements ('Requires a valid Bearer token') and cost implications are mentioned, offering clear guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
