fonzip_communication_permissions

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

Annotations already indicate the tool is not read-only and not destructive. The description adds that it can update and list changes, but it does not disclose deeper behavioral traits such as side effects of updates, required permission context, or response behavior. It neither contradicts annotations nor adds substantial behavioral insight.

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, compact sentence that front-loads the resource and immediately names the three supported operations. There is no filler or redundant restating of the tool name.

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 tool with nine parameters, three distinct actions, and no output schema, the description is too high-level. It does not explain that the action parameter determines required fields, nor does it mention pagination, date-based change listing, or return behavior. The schema carries most of the needed context.

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 parameter meanings and action-specific requirements. The description adds only high-level mapping to operations and does not enrich understanding of the nine parameters beyond what the schema provides.

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 (communication permissions for email/SMS/phone) and clearly lists three concrete operations: querying, updating, and listing changed permission statuses. This clearly distinguishes it from sibling tools such as fonzip_events or fonzip_donations.

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?

The resource domain is clear, so an agent can infer when this tool is relevant, but the description gives no explicit when-to-use guidance, no exclusions, and no comparison to alternatives. Usage is implied rather than stated.

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