update_privacy_settings

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

No annotations are provided, so the description must fully convey behavioral traits. It only states 'Update' without disclosing side effects (e.g., immediate effect, logout, connection required) or how unspecified settings behave (e.g., unchanged). This is insufficient for an agents safe reasoning.

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, concise sentence that immediately communicates the tools purpose and scope. It is well front-loaded and contains no redundant information.

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?

Given the tool has 7 parameters, no annotations, and no output schema, the two-line description is inadequate. It omits critical details like defaults, parameter interactions, and whether settings are independent or cumulative, making it incomplete for fully autonomous usage.

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 description adds context by listing the settings (profile, status, etc.), but does not explain the meaning of enum values (e.g., 'all', 'contacts') or the special 'match_last_seen' for online. With schema coverage at 14%, the description partially compensates but leaves gaps in interpretation.

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 verb 'Update' and the resource 'privacy settings of the instance', and lists the specific settings affected (read receipts, profile, status, online, last seen, group add). This differentiates it from sibling tools like fetch_privacy_settings.

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 no guidance on when to use this tool versus alternatives. It does not mention the prerequisite of having a connected instance or suggest fetching current settings before updating, leaving the agent without usage context.

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