bulk-update-account-permissions

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

With no annotations, the description must disclose behavioral traits. It only states it updates permissions, but omits critical details: whether it's atomic, merges or overwrites, permission requirements, error handling for partial failures, or rate limits. Minimal disclosure for a bulk mutation.

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 very concise at 5 words, efficiently conveying the core purpose. However, it could include more context without being verbose, such as hinting at the bulk nature or parameter dependencies.

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?

No output schema and no annotations. The description does not cover return behavior, success/failure signals, or effects on existing permissions. For a nested parameter tool, more context is needed to prevent misuse.

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 the schema already documents both parameters exhaustively. The description adds no additional meaning beyond the schema. Baseline score 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 the verb 'update' and resource 'permissions for multiple accounts', distinguishing it from sibling tools like 'update-account' (single account) and 'manage-account-permissions' (likely single account). The term 'bulk' further clarifies scope.

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 vs alternatives. For example, it doesn't mention that for single account updates, sibling tools like 'manage-account-permissions' or 'update-account' should be used. No prerequisites or contextual cues.

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