zernio_update_profile

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

The description only states 'Update' and gives no behavioral details beyond the schema. There are no annotations to clarify safety or side effects. As a mutation tool, the agent needs to know whether updates are partial or full, whether changes are reversible, and if there are permission requirements.

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, clear sentence with no wasted words. It is front-loaded with the verb and resource. While concise, it could be more informative without sacrificing brevity.

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 update tool with three optional parameters and no output schema, the description is adequate but minimal. It covers the basic purpose but lacks details on return values, edge cases, or behavioral context that would help an agent use it confidently.

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, so the schema already documents each parameter. The description adds no additional semantic information beyond what the schema provides, resulting in a baseline score of 3.

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 'Update the current user's Zernio profile information.' It identifies the verb (update), resource (profile), and scope (current user). However, it fails to distinguish from the sibling tool 'zernio_update_zernio_profile', which appears to have a similar purpose.

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. There is no mention of prerequisites, when not to use, or how it differs from similar tools like 'zernio_update_zernio_profile'.

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