get_user_settings

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

Annotations already declare readOnlyHint=true and idempotentHint=true, fully covering the behavioral safety profile. The description adds the detail that it retrieves from the 'user_settings table' and returns all settings, which is consistent and non-contradictory.

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, front-loaded sentence that efficiently states the verb, resource, and relationship to the sibling tool with no wasted 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?

Given zero parameters and no output schema, the description, combined with annotations, is complete for understanding the tool's purpose and behavior. It clearly specifies the data source and the sibling tool for single-key access.

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 tool has zero parameters (input schema empty), so schema description coverage is 100%. The description adds value by specifying that it returns 'all user settings', which clarifies the scope beyond the schema.

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 'Get all' and the resource 'user settings from user_settings table', and explicitly distinguishes it from the sibling tool 'get_user_setting' by noting it gets all settings versus a single setting by key.

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 on when to use this tool (to get all settings) and explicitly names the alternative sibling tool 'get_user_setting' for getting one setting by key, but does not mention any conditions when not to use it or other alternatives.

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