Get call details

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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds useful context about what is returned (timeline and transcription, if enabled) and the single-call scope, but it does not disclose output format, pagination, or behavior when transcription is disabled.

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?

One sentence with no filler: it front-loads the two key outputs (timeline, transcription) and then specifies the identifier source. Every word earns its place.

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 read-only tool, the description tells what is returned, the source of the required identifier, and the transcription caveat. It omits secondary details like output structure or error behavior, but nothing essential for correct invocation 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?

The schema only defines uuid as a non-empty string with no further meaning. The description compensates by explaining that the uuid comes from talk_list_calls, giving the parameter provenance and purpose. For a single parameter with 0% schema coverage, this is sufficient though minimal.

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 states a specific resource (event timeline and transcription for one call) and the retrieval action, and it distinguishes the tool by tying the identifier to the uuid produced by talk_list_calls. This clearly separates it from listing, status, and generic get siblings.

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 phrase 'by the uuid from talk_list_calls' gives clear context: obtain the call identifier from the list tool first, then use this tool for that specific call. It does not explicitly state exclusions or alternative tools, so it stops short of a 5.

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