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

With no annotations, the description carries full burden for behavioral disclosure. It discloses that the tool creates a new version, is non-mutating, and preserves omitted fields—valuable context for a write operation. However, it does not cover permissions, rate limits, or error cases, leaving some gaps.

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 highly concise, with two sentences that front-load the core purpose and then add key operational details. Every sentence adds value, making it efficient and easy to parse.

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?

Despite having an output schema, the tool has 8 parameters with nested objects and zero schema descriptions. The description explains versioning behavior but omits parameter semantics, prerequisites, and usage conditions. This is insufficient for an agent to correctly invoke the tool with appropriate field values.

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 0%, so the description must compensate for parameter meaning, but it does not explain any of the 8 parameters. It mentions 'fields' generically without detailing operator_id, quality_bar, trusted_sources, etc. This leaves the agent to infer semantics from property names alone, which is insufficient.

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 the operator profile and clarifies that it creates a new version with a provenance receipt rather than mutating in place. This distinguishes it from sibling tools like get_operator_profile (read-only) and update_constraint (different resource).

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 clear context: partial updates are accepted and unspecified fields are preserved. It implies usage for updating operator profile fields, though it does not explicitly mention alternatives or when-not-to-use scenarios. The guidance is sufficient for most cases but lacks explicit exclusions.

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