trello_action

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

No annotations are provided, so the description carries the full burden. It only says 'Interact with the Trello REST API', which is generic. It does not disclose side effects (e.g., create/update are destructive), rate limits, authentication needs beyond what's in the schema, or return value structure.

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 concise sentence that covers the tool's scope. It is front-loaded with the key information but is slightly too brief; it could benefit from a bit more detail without becoming verbose.

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 (17 parameters, 6 actions) and lack of output schema or annotations, the description is inadequate. It does not explain how to use the tool end-to-end, what results look like, or how actions relate to parameters. A more complete description would include return value hints or 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?

Schema coverage is 100%, so each parameter has a description in the schema. The tool description adds no additional semantic information beyond listing the action types, which is redundant with the enum. Baseline 3 is appropriate.

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 that the tool interacts with the Trello REST API and lists specific actions like list boards, create cards, etc. It is precise about the resource (Trello) and the operations, distinguishing it from sibling tools which are other platform wrappers.

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 on when to use this tool versus alternatives like airtable_action or clickup_action. The description does not mention prerequisites, recommended scenarios, or exclusions.

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