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

No annotations are provided, so the description carries the full behavioral burden. 'Fetch' implies a read operation, but the description does not disclose authorization requirements, rate limits, error behavior, or return characteristics; the subscriber-token detail appears only in the schema's access_token field.

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 a single short sentence with no wasted language and front-loads the core action. 'PRO' is slightly cryptic, but the overall structure is maximally concise.

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 two-parameter lookup, the description is minimally sufficient: it says what is fetched and where the ID comes from. But with no annotations and no output schema, it could do more to clarify the expected return shape or authentication expectations beyond the schema's access_token field.

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 50%. The description adds useful provenance for speech_id by saying it comes from search results, while the access_token parameter is documented in the schema itself. This is adequate but not full compensation for the undocumented speech_id schema entry.

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: 'Fetch one speech by speechID.' It clearly identifies this as a single-item lookup rather than a search, implicitly distinguishing it from the speech_search siblings, though it does not name those alternatives explicitly.

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 '(from search results)' implies the speechID should come from prior search output, giving some usage context. However, it does not explicitly state when to use this versus speech_search or speech_search_pro, nor any exclusions or prerequisites.

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