configure_plugin_chat

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

With no annotations, the description carries full burden. It clearly discloses mutation via the '[mutation]' tag and explains partial update behavior, including automatic merging of JSON fields (config_design, config_texts, config_behavior). However, it does not detail error handling, idempotency, or what happens to unspecified fields.

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 extremely concise: two sentences and a tag. The first sentence clearly states the purpose, and the second provides critical behavioral detail about partial updates. No redundant or unnecessary information. Every word earns its place.

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?

Given the complexity (14 parameters, nested JSON objects, no output schema, no annotations), the description is adequate but lacking. It covers partial update behavior but omits response format, error scenarios, permission requirements, or expected outcomes. A more complete description would include success/failure indicators and usage examples.

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?

Input schema has 100% coverage with descriptions for all 14 parameters, so baseline is 3. The description adds significant value by explaining that JSON fields (config_design, config_texts, config_behavior) support partial updates and merging, which is not evident from the schema alone. This clarifies how to use those parameters effectively.

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 configures the chat web widget (verb 'Configurar' and resource 'plugin Chat'/'widget de chat web'). While it differentiates from other configure tools by specifying the chat plugin, it does not explicitly distinguish it from sibling tools like 'configure_plugin_productqa' or 'configure_webhooks', missing a clear differentiator.

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. The description does not mention any prerequisites, exclusions, or scenarios where this tool is appropriate over other configure_plugin tools. The agent must infer usage purely from the tool name and resource focus.

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