Update a Nuvio profile

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

The description discloses key behaviors beyond annotations: it snapshots the previous state before the write, supports dry_run to avoid writes, and can be reverted via nuvio_undo. Annotations only indicate it's a write and non-destructive, so this adds valuable context about reversibility and dry-run capability.

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, well-structured sentence that front-loads the core purpose ('sparsely update one profile'), lists the relevant fields, and adds behavioral notes (dry_run, snapshot, revert). No unnecessary words.

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 tool with 7 parameters and no output schema, the description omits crucial information: what the function returns (e.g., the updated profile or a diff when dry_run is true), how omitted fields behave (remain unchanged), and any prerequisites (e.g., profile must exist). It doesn't clarify the response format, which is especially important given no output schema.

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 only 14% (only dry_run has a description). The description lists the updatable fields but doesn't explain semantics for each parameter, such as the relationship between avatar_id and avatar_url, nullability implications, or that profile_id is the required identifier. It compensates minimally by listing the fields, but insufficiently for low schema coverage.

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 a single profile with specific fields (name, avatar color, avatar id/url, uses_primary_addons), using 'sparsely update' to indicate partial modification. It distinguishes from create/delete siblings by the verb 'update' and resource 'profile', though it doesn't explicitly name alternatives.

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 'sparsely update' and dry_run, but provides no explicit guidance on when to use this tool versus nuvio_create_profile, nuvio_delete_profile, or other update tools. It doesn't state when not to use it or what conditions select this tool.

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