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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description still earns credit by disclosing the response shape (verdict + score, or 'research is still running') and by pointing out that full reports live on the project page rather than being returned here — useful non-obvious behavior.

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?

Two sentences, zero filler, with the primary trigger and the return payload front-loaded and the exclusion placed last. Every clause carries information.

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 single-parameter read tool with an output schema and full annotation coverage, the description supplies the decision criteria, the returned verdict semantics, and the boundary against the sibling interview tool. Nothing an agent needs to call it correctly is missing.

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 description coverage is 0%, so the description technically carries the burden, but it says nothing about project_id beyond implying a project is selected. The parameter name is largely self-explanatory and the schema supplies a format pattern, so this is adequate rather than deficient, but no added meaning is provided.

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 and resource ('get ... result' for a GoNoGo project) and enumerates exactly what is returned: the GO / NO-GO verdict and score, or a still-running status. It also names what it is not ('Do not use to start a new interview'), which cleanly separates it from the interview_with_alex sibling.

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?

Gives an explicit trigger ('when the user asks for the verdict, score or research status'), a concrete example scenario ('after finishing an interview with Alex'), and an explicit exclusion ('Do not use to start a new interview'). The routing decision is fully determined without opening any schema.

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