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

Goes well past the annotations: revoke is immediate on every channel, delegates act with their own token/session, every act is recorded under their account in the audit trail, a transfer resets access, and the tool cannot be used with a managementToken. These are exactly the operational traits annotations cannot convey, and nothing here conflicts with idempotentHint/destructiveHint.

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?

Front-loaded with the action semantics before the role coverage, so the important routing information comes first. The two long enumeration lists (what 'mainteneur' covers and does not cover) are dense, but each item carries real scoping information rather than filler.

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 4-parameter mutation tool with annotations but no output schema, the definition covers auth requirements, side effects, and role scope thoroughly. Minor gaps remain: no indication of what a 'list' response contains and no explanation of dropId's role.

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 only 50% (action and dropId lack schema descriptions), and the description compensates well: it defines each action value, the default, that email must belong to an EXISTING Dropyour account, and that revoke takes email. Only dropId's semantics remain unelaborated beyond the schema's pattern.

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 states a precise verb+resource ('Let ANOTHER Dropyour account maintain one of your apps... take it back at any time') and enumerates the four actions. It is clearly separable from siblings like dropyour_delete or dropyour_update_settings, since it explicitly says those powers are NOT covered by the granted role.

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?

Strong context: it names the typical scenario (integrator transfers an app to a client, then the client grants 'mainteneur'), gives the pre-condition ('Requires a connected account (no managementToken)'), and lists what the role cannot do, which implicitly routes to other tools. It stops short of naming specific sibling tools as alternatives for the excluded operations.

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