update_account

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

Annotations already provide key behavioral traits: non-read-only (mutation), idempotent, non-destructive. The description adds no extra context beyond stating 'Update'. With annotations covering the safety profile, the description adds minimal value, scoring a baseline 3.

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 concise sentence, front-loaded with the action verb. It contains no unnecessary words, but could be structured to include more context without sacrificing brevity, thus a 4 rather than 5.

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 full schema descriptions, existing annotations, and an output schema, the description is minimally sufficient for a simple update tool. However, it lacks guidance on error handling, success behavior, or special cases, so it is adequate but not comprehensive.

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?

Input schema has 100% description coverage for all 7 parameters, including account_id. The tool description adds no additional meaning to the parameters beyond summarizing them as 'settings or details', so it meets the baseline 3 without further enrichment.

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 specifies the action 'Update' and the resource 'account', clearly indicating modification of an existing account. It is distinct from sibling tools like 'create_account' or 'delete_account', fulfilling the criteria for a specific verb+resource and differentiation.

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, such as when to update vs. create or delete. There is no mention of prerequisites, context, or exclusions, leaving the agent without usage direction.

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