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

Annotations declare readOnlyHint=false, signaling possible mutations, but the description does not add any context about side effects, permission requirements, or the risk of calling arbitrary methods. Since the tool can invoke any model method, including destructive ones, the lack of warning is a significant gap. The description adds nothing beyond what the annotation already implies.

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, efficient sentence that front-loads the core verb and resource. It includes two illustrative examples that aid understanding without excess words. It is concise and well-structured, though it could benefit from a brief usage 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?

For a generic method executor with readOnlyHint=false, the description is incomplete. It does not warn about potential data mutation, mention that method availability varies by model, or clarify error behavior. The tool is powerful and potentially dangerous, yet the description gives no guidance on safe invocation. Even with an output schema present, the lack of caution makes it under-specified.

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 has 100% description coverage for all four parameters (model, method, args, kwargs), so the schema already explains their purpose. The description adds no extra semantic detail, such as how arguments should be formatted or examples of common methods. With full schema coverage, a baseline of 3 is appropriate; no bonus is earned.

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 verb 'Llama' (calls) and the resource 'cualquier método del modelo' (any method of the model), with concrete examples like 'confirmar pedidos, validar facturas'. This distinguishes it from sibling tools like odoo_read, odoo_write, and odoo_create by positioning it as a generic method executor. It is not a tautology and gives a solid sense of what the tool does.

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 gives no explicit guidance on when to use this tool versus the alternatives. It implies that it is for calling arbitrary methods not covered by specialized tools, but it does not state exclusions or recommend this only for specific scenarios. An agent cannot determine when to prefer odoo_execute over odoo_read or odoo_write based on this text.

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