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

With no annotations, the description should disclose behavioral traits. 'Retrieve' implies a non-mutating lookup, and 'full content' hints at the outcome, but it does not describe error behaviors, return format, or access restrictions. This is the minimum viable transparency.

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; the verb and object are front-loaded. It is an ideal concise description for the given function.

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 one-parameter retrieval tool with no output schema, the description is generally adequate, but it misses reinforcement of usage context and return expectations, leaving some ambiguity for an agent deciding whether this fulfills a request.

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?

The input schema already describes page_path thoroughly (repo path, short path, or GitHub URL), and the tool description adds no extra semantic beyond the page reference. At 100% schema coverage, the baseline 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 names a clear action ('Retrieve') and a clear resource ('full content of a specific documentation page'). It is easy to distinguish it from search-like siblings, but it does not explicitly contrast with them, so it falls slightly short of full sibling differentiation.

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?

No guidance is given on when to pick this tool over list_documentation_sections, search_documentation, or get_cheaha_quick_start. The description only states the function, leaving the agent to infer that it is for known page paths.

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