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

Beyond the annotations (readOnly false, destructive false, idempotent true), the description discloses verification before mutation, the RSS feed impact on the next build, and the one-to-one ownership constraint. This adds substantial behavioral context.

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 three sentences, each serving a distinct purpose: the action, the verification mechanism, and the scope. No redundancy or fluff.

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 description covers purpose, prerequisites, effects, and constraints. It lacks explicit return value or error behavior, but for a mutation tool with no output schema, the provided context is sufficient for an agent to select and invoke the tool.

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?

The input schema already provides descriptions for all 4 parameters, including referencing publisher_upload_audio for the key. The description adds the one-to-one constraint but does not provide additional parameter-level detail beyond what the schema covers.

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 clearly states the tool confirms a finished upload and attaches it to an episode, making it live. It distinguishes from sibling publisher_upload_audio by specifying the attach step and the RSS feed effect.

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 description implies usage after upload via the key reference and 'Confirm a finished upload'. It does not explicitly name alternatives, but the context is clear enough for an agent to infer the correct sequence.

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