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

No annotations are provided, so the description carries the burden. It usefully notes that only 'published' content is returned, implying a scope/visibility constraint, but says nothing about permissions, error behavior for missing or unpublished ids, or response size/pagination. Adequate but thin for an unannotated tool.

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?

A single sentence with zero waste, front-loading the action and result before naming the input source. Nothing needs trimming and nothing essential is buried.

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?

For a simple two-optional-parameter read tool with no output schema, the description covers purpose, input source, and result shape ('full text'), which is enough to call it correctly. The remaining gap is guidance on the id/path interaction when neither is required.

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 description coverage is 100% and both parameters have their own examples (ids and paths), so the schema already does the heavy lifting. The description adds only the provenance hint that the id comes from search_knowledge; it does not clarify how id and path interact when both are optional.

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?

States a specific verb and resource ('Return the full text of one published page or guide') and scopes it to a single document, which distinguishes it from the sibling search_knowledge that produces candidate ids. An agent can tell immediately this is the fetch-one step after a search.

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?

Explicitly tells the agent where the input comes from ('using an id from search_knowledge or its path'), which is a clear usage condition tying it to the retrieval workflow. It stops short of stating exclusions, such as when to prefer path over id or that unpublished docs cannot be fetched.

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