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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds that results are recency-ordered and include IDs and status, which is useful since there is no output schema, but it says nothing about how many are returned, ordering ties, or what happens beyond the cap.

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 front-loaded sentence with no filler; every clause (recency, account scope, returned fields) earns its place. It is efficient, though one short clause about volume or ordering would have improved it at negligible cost.

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 read-only listing tool with one optional parameter and no output schema, the definition covers purpose, scope, and returned fields. The remaining gap is the absence of any mention of result count or pagination behavior, which is minor at this complexity.

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?

There is only one optional parameter (limit, default 10, max 50) and the schema is largely self-explaining even though its description coverage is 0%. The word 'recent' plus 'most recent' implies a bounded, newest-first window, but the description never mentions the limit or its cap, so it adds no meaning beyond the schema.

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 gives a specific verb and resource ('Lists the most recent transcription jobs') plus the fields returned (IDs and status), which is enough to distinguish this from get_transcript, which clearly fetches one job. It stops short of explicitly contrasting with the siblings, so it lands just below the top mark.

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?

Usage is only implied by the word 'recent' – an agent can infer this is the entry point for browsing before calling get_transcript, but the description never states when to use it, when not to, or what the alternatives are. No prerequisites or exclusions are given.

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