set_config

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

Annotations already provide readOnlyHint=false, idempotentHint=true, destructiveHint=false. Description adds HTTP method (PUT) and clarifies idempotency, but does not disclose additional behavioral traits like required permissions or side effects. Consistent with annotations.

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?

Description is concise but includes redundant statements ('Update settings' and 'Modifies an existing record'). The emoji and HTTP method are informative but not structured for easy scanning. Could be more efficient.

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?

No output schema is provided, and description does not clarify the response format. The tool's purpose is unclear without knowing what 'settings' are updatable. Given minimal schema and annotations, the description is insufficiently complete.

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 coverage is 100% but only includes an 'id' parameter; description does not explain what other fields can be updated or the format of the request body. Adds no meaning beyond the schema, which is sparse.

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 identifies the action ('updates data', 'Update settings') and resource ('Configs'), but the resource is vague; it doesn't specify what kind of config. It distinguishes from sibling update tools only by name, not by explicit differentiation.

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 on when to use this tool versus alternatives. No mention of prerequisites, context, or when not to use. The description only states the operation without any usage direction.

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