update-account

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

No annotations are provided, so the description must disclose behavioral details. It states 'Update an existing user account,' implying mutation but does not mention potential side effects (e.g., deactivation via the 'active' field), required permissions, or any irreversible impacts. This is insufficient for a tool with no other behavioral hints.

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 two sentences long and front-loads the key action and resource. Every sentence adds value: first defines scope, second clarifies use cases. No unnecessary filler.

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 has 11 parameters, no output schema, and no annotations, the description is too brief. It does not explain return values, validation requirements, or the implications of specific fields like 'active' or 'account_type.' The description alone does not provide enough context for complete agent understanding.

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 baseline is 3. The description adds a high-level categorization of parameters (contact details, permissions, etc.), which provides some semantic grouping but no additional constraints or usage nuances beyond what the schema already offers.

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 tool updates an existing user account and lists specific aspects like contact details, permissions, timezone settings, and account configuration. It provides a clear purpose but does not explicitly differentiate from sibling tools like update-account-timezone or bulk-update-account-permissions.

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 mentions 'Use for profile management and access control updates,' which gives context on when to use. However, it lacks explicit guidance on when not to use or alternative tools, leaving some ambiguity among related siblings.

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