form_get_binding_action

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

The annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint, so the safety profile is covered. The description adds the GET endpoint path and input concepts, but it does not explain what a binding action is, what the response contains, or any auth/rate-limit behavior.

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 short and front-loaded with the core operation. The second sentence repeats the endpoint already present in the title annotation, so it is slightly redundant.

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 simple two-parameter read tool, annotations and full schema coverage make it callable. However, with no output schema, the description does not explain return values or clarify the domain meaning of a binding action, leaving a noticeable contextual gap.

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 description coverage is 100%, so both resourceType and externalType are documented in the schema. The description mirrors those parameter names without adding format, allowed values, or coupling semantics beyond the schema.

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 uses a specific verb-resource pair: get binding action for an action resource type and external input type. It is clear enough to understand the basic purpose, but it does not differentiate this tool from nearby siblings such as form_get_resource_action or form_get_action_form.

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 states the required inputs but gives no guidance on when to use this tool versus alternatives. There is no mention of prerequisites, exclusions, or sibling tools, so the agent must infer usage from the name and schema.

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