spix_call_summary

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

No annotations provided, and the description only indicates a read operation ('Get'). It does not disclose behavior when the call has no summary, or whether the summary is generated synchronously. The minimal description leaves the agent uninformed about edge cases.

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?

The description is one short sentence, which is efficient and front-loaded. However, it could be slightly expanded to improve completeness without losing conciseness.

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?

Given the lack of annotations and output schema, the description is insufficient. It does not explain what the summary contains, its format, or conditions for availability, leaving the agent with significant uncertainty.

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% for the single parameter 'session_id' (described as 'Call session ID'). The description adds no further semantics, so 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?

The description 'Get AI-generated call summary' uses a specific verb ('Get') and resource ('AI-generated call summary'), clearly distinguishing it from siblings like spix_call_show (call details) and spix_call_transcript (transcript).

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?

No explicit guidance on when to use this tool vs. alternatives, nor any prerequisites (e.g., call must be completed). The context from sibling names implies it is for post-call summary retrieval, but this is not stated.

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