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

Annotations already declare readOnlyHint=true and destructiveHint=false, and the description reinforces this with 'opens nothing by itself,' removing any doubt about side effects. It also discloses the return content ('screens, buttons, fields') and notes there is no official Podium MCP server, which explains why a guide-based approach exists. The final API detail is informative but not strictly behavioral.

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?

Three sentences, front-loaded with purpose and immediately followed by the crucial 'opens nothing by itself' caveat and the routing instruction. The closing sentence about Podium's official REST API and lack of an MCP server is tangentially useful justification but slightly off-task for selecting and invoking the tool.

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?

With no parameters and no output schema, the description carries the burden of explaining what comes back, and it does so ('step by step (screens, buttons, fields)'). It is complete enough for an agent to call it and know the result is guidance, not an executed payment; only the shape of the returned guide (text vs structured) is left unstated.

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 tool takes zero parameters, so there are no semantics to clarify and the baseline applies. The description correctly implies no inputs are required by presenting the tool as a self-contained lookup.

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 names a specific action (request payment) in a specific product and clarifies the actual mechanic: it 'Returns how to do it in Podium step by step.' The leading clause 'Request payment in the user's own Podium account from ChatGPT, Claude or any AI agent' initially reads as if the tool performs the action, and is only corrected by the following sentence, which slightly blunts the clarity.

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?

It gives an explicit next step and alternative: after getting the guide, 'do it with the cotlet_browser_* tools in the user's Podium Cloud Browser.' That correctly routes the agent to the browser siblings. It does not state when not to use this tool (e.g., versus a direct Podium API path), but the sequencing guidance is clear.

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