updatePrivacySettings

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

No annotations are provided, so the description bears full responsibility. It only says 'Updates' without disclosing whether the operation is destructive, requires authentication, or affects other settings. The behavioral impact is unclear.

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 sentence and front-loaded, but it is underspecified. Conciseness does not compensate for missing critical details.

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?

With no output schema, partial parameter descriptions, and no annotations, the description lacks completeness. It does not explain return values, side effects, or the meaning of the two boolean parameters.

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 33% (only profile_id described). The tool description adds no meaning to the parameters disguisedTrackers or allowAffiliate, leaving the agent to infer their purposes from names alone.

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 'Updates privacy protection options,' which gives a clear verb and resource. However, it is vague and does not specify which privacy options (e.g., tracker disguising, affiliate tracking) are involved, nor does it differentiate from sibling tools like updateSecuritySettings or updateBlockPageSettings.

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. With many sibling update tools, the description should indicate the specific context or scenarios for updating privacy protection options, but it does not.

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