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

With no annotations, the description carries the transparency burden. It indicates a read operation ('one read') and a comprehensive return, but it does not describe the exact output format, potential errors, or side effects, leaving some ambiguity.

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, clear sentence that efficiently lists the documentation topics. It is well-structured with no redundancy, making it easy to parse and act upon.

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 the simplicity of the tool and lack of output schema, the description provides enough context for typical use. However, it omits details about the return format (e.g., text or JSON) and any edge cases (e.g., missing docs), so it is not fully 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?

Since there are no parameters, the input schema is empty and fully covered. The description adds no parameter-specific information, so a baseline score of 3 is appropriate per the guidelines.

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 tool's purpose: retrieving the complete OAIA agent interface documentation. It specifies the covered topics (commit format, signing, scoring rule, registration flow) and distinguishes itself from sibling tools that perform actions like committing or registering.

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 implies usage when documentation is needed, but it does not explicitly state when to use this tool over others. There is no comparison to alternatives, though the sibling context suggests it is the go-to for interface reference.

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