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

Annotations already declare readOnlyHint=true and idempotentHint=true, and the description is consistent with them by stating it 'opens nothing by itself'. Beyond that it discloses the return shape (step-by-step screens, buttons, fields) and explains why the API route is unavailable on One App Free/Standard plans, which justifies the browser fallback. The undated-looking 'checked 14 Oct 2026' caveat is odd but the disclosure level is above the annotation baseline.

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 core sentence about returning steps and using the browser tools is front-loaded and earns its place, but the lead-in 'from ChatGPT, Claude or any AI agent' is promotional filler. The closing paragraph on Odoo Online API plan restrictions is relevant context yet verbose, with a dated check that reads like a changelog note.

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 what to do next, and it does both. An agent knows it receives navigation instructions and must then drive the browser. It could still name the concrete prerequisites (e.g. which invoice/payment to register) but is otherwise sufficient for a zero-arg 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 tool takes zero parameters, so there is nothing for the description to disambiguate; baseline is 4. The description correctly implies no inputs are needed to obtain the instructions, and adds no misleading parameter language.

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?

Names a specific verb and resource (register payment in the user's Odoo account) but then immediately re-scopes the function: it returns step-by-step instructions and 'opens nothing by itself'. That clarification is valuable because the name alone would suggest an action tool, yet the opening line and the 'step by step (screens, buttons, fields)' detail make the real behavior unambiguous.

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?

Explicitly states the follow-up workflow: get the steps here, then execute with the cotlet_browser_* tools in the user's Odoo Cloud Browser. That is a clear alternative-routing instruction rather than an inferred one. It does not say when NOT to use it or point to adjacent Odoo tools (e.g. listing unpaid invoices to identify the target), so it falls short of full when/when-not coverage.

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