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

The annotations already establish read-only, idempotent, non-destructive behavior. The description adds a meaningful behavioral/safety note that transcript text is user-supplied recording content, which is useful context beyond the annotations, though it does not discuss pagination termination or result limits.

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 followed by a relevant content-safety note. There is no wasted wording.

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?

The annotations and output schema reduce the description's burden, and it covers scope plus user-supplied-content safety. Still, with four parameters and 0% schema description coverage, it leaves pagination mechanics and parameter behavior too implicit for a fully complete definition.

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 0%, so the description must compensate for undocumented parameters. 'Bounded page' loosely gestures at cursor/pageSize/characterBudget, but it does not explain cursor semantics, the relationship between pageSize and characterBudget, or the transcriptionId format beyond what the schema already enforces.

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 verb and resource: 'Reads a bounded page from a completed transcript.' It clearly scopes the tool to paginated reading of completed transcripts, though it does not explicitly name sibling alternatives such as get_transcript_artifact or export_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?

The phrase 'completed transcript' implies the tool should be used only after transcription has finished, and 'bounded page' implies paginated reading. However, there is no explicit guidance on when to choose this over get_transcript_artifact, export_transcript, search_library, or edit_transcript_text.

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