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

Annotations already indicate a mutating (readOnlyHint=false) but non-destructive operation, and the description adds a meaningful behavioral consequence: only an ACTIVE binding delivers, so inactive/draft statuses suppress delivery. This goes beyond the structured 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?

Two short sentences deliver the action and the key business rule with no filler. The purpose is front-loaded and 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?

For a two-parameter, fully schema-documented mutation with no output schema, the description provides sufficient context: what action to take, the valid statuses, and the behavioral consequence. It could include a pointer to related tools or side effects, but those are not essential for this simple operation.

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 the schema already documents binding_id and the status enum. The description reinforces that statuses are active/inactive/draft but adds no parameter-specific meaning 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 names a specific resource (partner binding) and the exact action (activate, deactivate, or draft), making the tool's purpose obvious. It is clear enough to distinguish from general create/update/delete siblings, though it does not explicitly name a distinguishing sibling.

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 given about when to use this tool instead of update_partner_binding or other status-related siblings. The sentence 'Only an ACTIVE binding delivers' implies why status matters, but it does not state selection criteria or exclusions.

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