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

No annotations are provided, so the description carries the burden. It discloses the status values and that output_url appears only when completed, which is useful behavioral context. However, it does not mention polling behavior, error cases, or whether the job result is retained/deleted, which would be valuable for a job-status tool.

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, front-loaded with the core purpose and return fields, then a useful sibling comparison. No wasted words.

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 single-parameter fetch tool, the description covers the purpose, the return fields, and the relationship to sibling tools. It lacks explicit polling/error behavior, but the simplicity of the tool and the 100% schema coverage make the definition largely 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?

Schema description coverage is 100% and the single parameter 'id' is already described as 'Transcribe job UUID'. The description adds that the ID refers to a transcribe job created via transcribe_audio, which is a small clarification, but it does not add format or source details beyond the schema. Baseline 3 is appropriate.

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 ('Fetch'), a specific resource ('current state of a single transcribe job by ID'), and the exact fields returned (status values and output_url). It also explicitly distinguishes itself from the sibling get_transcode, so an agent can tell them apart without opening schemas.

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 says it mirrors get_transcode but for SRT generation jobs created via transcribe_audio, which gives clear context for when to use it. It does not explicitly state when not to use it or name alternatives beyond get_transcode, but the context is sufficient for a single-ID fetch tool.

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