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

With no annotations, the description carries full responsibility for behavioral disclosure. It only indicates the return format (plain text) and does not address error conditions, auth requirements, or whether 'chunkId' has any bounds or properties beyond what the schema already specifies (minimum 0).

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, front-loaded sentence ('Get a specific transcript chunk as plain text') with no filler or redundant information. It is concise and structured effectively.

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 tool has no output schema and no annotations. The description is too sparse to provide complete context; it doesn't explain how the chunk is identified, what constitutes a chunk, or what the client should expect in the response beyond 'plain text'. This is insufficient for a full understanding.

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% (no parameter descriptions). The description does not explain the 'guest' parameter (e.g., slug vs. ID) or the meaning of 'chunkId' beyond the schema's type and minimum. Parameter names are self-explanatory to a degree but the description adds no semantic value.

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 uses a specific verb 'Get' and identifies a specific resource 'a specific transcript chunk' as plain text, which clearly distinguishes it from sibling tools like getEpisodesGuestChunks (presumably listing chunks) and getEpisodesGuestTranscriptformat (full 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 guidance is provided on when to use this tool versus alternatives. It doesn't mention that it should be used after obtaining a chunk ID from getEpisodesGuestChunks, nor does it exclude other tools. The usage context is only implied by the tool name.

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