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

No annotations are provided, so the description carries the full burden. It only states 'update' but does not disclose side effects, required permissions, idempotency, error responses, or consequences of updating a group. A mutation tool without behavioral context is risky.

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 short sentence, which is concise but arguably too terse. It is front-loaded with the key action and resource. However, it could be improved by including more context without becoming verbose. It is adequate but not excellent.

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?

Given the tool's simplicity (3 params, no output schema, no nested objects), the description is somewhat incomplete. It does not mention return behavior, error conditions, or success indicators. While the schema covers parameters, the description misses critical context for a mutation 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?

The input schema has 100% description coverage for all 3 parameters. However, the description adds no extra meaning beyond the example of 'name'. It does not clarify how to obtain groupId or accountId, or the relationship between them. Baseline for full schema coverage is 3, but the lack of added value reduces it to 2.

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 action ('update') and the resource ('WhatsApp Group details'), with an example ('name'). It distinguishes from sibling tools like create or delete. However, it implies more than just name can be updated, but the schema only shows name as a mutable parameter, causing slight ambiguity.

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 description provides no guidance on when to use this tool versus alternatives (e.g., update_whatsapp_template). There are no prerequisites, limitations, or when-not-to-use instructions. The agent has no help in deciding between this and other update tools.

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