profile_create

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

No annotations are provided, so the description must carry the behavioral disclosure burden. It discloses only that a profile is created, not side effects, required inputs, failure modes, response behavior, or implied constraints such as needing a valid group_id. For a mutating create operation, this is a significant transparency gap.

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 one clean, front-loaded sentence with no filler. It is efficiently written, though it is a simple statement rather than a structured explanation that leverages the richness of the tool's 30 parameters.

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?

There is no output schema and no annotations, so the description alone must make the tool safely invocable. It omits the required group_id dependency, proxy method interaction (none/saved/your), defaults, and expected result. For a 30-parameter creation tool, this is incomplete.

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%, and the schema already documents all 30 parameters, their enums, defaults, and conditional meanings. The description adds no parameter-level meaning beyond the schema, so the baseline of 3 is appropriate.

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 states a specific verb ('Create') and a specific resource ('browser profile'), and the mention of fingerprint and proxy settings gives clear scope. It is clearly distinct from profile_update, profile_delete, and proxy_create by its wording. However, it does not explicitly contrast with sibling tools, so it stops short of a 5.

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 gives no guidance on when to use this tool versus alternatives such as profile_update, profile_delete, or proxy_create. It only declares what the tool does, with no conditions, prerequisites, or 'use this when...' direction.

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