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

No annotations are supplied, so the description carries the full behavioral burden. It usefully discloses the return format ('full Markdown') and the non-obvious behavior that a section's id resolves to its parent page, but it says nothing about read-only guarantees, auth/permission requirements, or whether fetches are cached or rate-limited.

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?

One dense sentence with the resource and return format front-loaded and the id-provenance caveat tucked into a parenthetical. Nothing is padded and no sentence is wasted.

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?

With an output schema present, the description need not explain return values, and its single-parameter, read-only surface is small. It covers what the tool does, where the id comes from, and the section-id edge case, though it omits error handling and sibling disambiguation.

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 a single documented id parameter, establishing a baseline of 3. The description goes beyond the schema by explaining where the id originates ('from search') and that a section-level id silently resolves to the containing page, which is meaningful input semantics an agent would otherwise miss.

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+resource: 'Return the full Markdown of one docs page,' which tells the agent exactly what comes back rather than a vague 'get page'. It ties the input to 'an id from search', implicitly distinguishing it from search tools, but it never contrasts with the very similar sibling get_page, leaving the closest alternative unresolved.

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 phrase 'by an id from search' implies the intended workflow (search first, then fetch), and the parenthetical hints that section ids are acceptable. However, there is no explicit statement of when to use this over get_page or what happens when an id is invalid or missing, so usage is only implied.

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