Session Report

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

The description says 'save a Markdown report,' implying a write operation, but annotations set readOnlyHint=true, indicating it should not modify state. This is a direct contradiction.

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 sentence, concise and front-loaded with the main purpose. However, it sacrifices clarity for brevity, leading to ambiguity.

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 no output schema and two parameters, the description is incomplete. It does not describe the return value or parameter details, and the contradiction with annotations undermines completeness.

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 description does not explain any of the two parameters (session_id, response_format). Schema description coverage is 0%, so the description should compensate but fails to do so. Additionally, the description mentions Markdown but response_format defaults to json, causing further confusion.

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 it generates and saves a Markdown report listing specific contents (convergence, peer decisions, etc.), which provides a clear verb and resource. However, it does not distinguish from sibling tools like session_events or session_check_convergence, which might overlap.

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?

There is no guidance on when to use this tool versus alternatives. No context about prerequisites or typical use cases is provided.

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