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 goes beyond that by detailing the response shape (speaker/text/timestamp segments, overall status and duration) and naming the underlying REST endpoint, which helps an agent anticipate what it will receive.

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 compact sentence that front-loads the action and return content, followed by a short REST reference. No filler or redundancy.

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?

With no output schema, the description usefully characterizes the transcript payload, and for a single-parameter read tool that is nearly sufficient. Minor gaps remain: no mention of what happens if a transcript is missing/unavailable, nor any size or pagination considerations for long calls.

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% and the single 'id' parameter is fully documented there (including the 'AC' prefix). The description adds only 'by its id', so it neither clarifies nor misleads — baseline 3 for a fully-schema-documented parameter.

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 the transcription for a call) and enumerates the returned content: dialogue segments with speaker, text, timestamps, plus status and duration. This clearly separates it from siblings like get_call_summary and get_call_recordings, so an agent can route correctly without opening any schema.

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 implied by the return content (use it when you need the actual dialogue, not a summary), but the description never states when to prefer this over get_call_summary, get_call, or get_call_recordings, nor any preconditions such as requiring the call to have been transcribed.

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