update_custom_attribute_in_account

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

No annotations are available, and the description does not disclose behavioral traits such as whether the update is idempotent, what fields can be changed, required permissions, or side effects. For a mutation tool, this is insufficient.

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 sentence with no extraneous words. However, it is too brief to convey useful information beyond the basic action, making it minimally viable.

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 simple one-parameter tool with no output schema, the description fails to provide sufficient context about the update behavior or expected result. It lacks completeness even for a low-complexity tool.

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 fully describes the 'id' parameter, but the description adds no extra meaning. It does not explain what properties are being updated or how the update is performed. The schema coverage is 100% but the description provides no additional value.

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 'Update custom attribute in Account' clearly states the action (update) and the resource (custom attribute in an account). It distinguishes itself from sibling tools like add, get, delete, and get details.

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 provided on when to use this tool versus alternatives like adding or deleting a custom attribute, or any preconditions or dependencies.

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