Get a single benchmark summary by id

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

No annotations are provided, so the description carries the behavioral disclosure burden. It does disclose that this is a fetch/read operation and that the response includes a full summary JSON blob, but it says nothing about not-found behavior, authentication, rate limits, or error handling. Adequate but not rich.

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 front-loaded sentence with no filler. It states the action, resource, and return detail efficiently.

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 one-parameter get-by-id tool with no output schema, the description covers the essential call purpose and return content well. It lacks explicit error or edge-case behavior and sibling routing, but the low complexity keeps this gap minor.

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%, so the schema already fully documents the single required 'id' parameter. The description's mention of 'UUID id' aligns with the schema but adds no new meaning beyond confirming that the parameter is the lookup key.

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 action ('Fetch'), the resource ('one summaries row'), and the lookup criterion ('by its UUID id'). It also mentions the distinctive return content ('full summary JSON metrics blob'), which helps distinguish it from list-oriented siblings like list_summaries.

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 a targeted single-row lookup by id, which is clear enough for a simple get-by-id tool. However, it does not explicitly say when to prefer this over list_summaries or mention any exclusions or alternative routing.

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