Update Project Incidents Configuration

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

The description goes well beyond annotations by disclosing partial update semantics, defaulting of project_id, the request payload nesting behavior, return value, and specific HTTP error statuses (401, 403, 404). This is rich, non-obvious behavioral context that significantly aids the agent in anticipating side effects and failures.

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 densely informative but every sentence earns its place—purpose, modifications, permissions, partial update, payload handling, defaulting, return value, failures, and endpoint reference. It is front-loaded with the primary purpose and structured logically without redundancy.

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?

For a 3-parameter update tool with no output schema, the description is exceptionally complete. It covers return values, error scenarios, permissions, defaults, partial update semantics, and API context. No significant information gaps remain for an agent to invoke the tool confidently.

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?

Despite 100% schema coverage, the description adds meaningful parameter semantics: the Read-level permission constraint on default_distribution_ids, the PATCH-like partial update behavior, and the clarification that fields are passed as top-level arguments despite being nested in the payload. These insights help the agent format arguments correctly and understand validation rules.

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 uses a specific verb ('Updates') and clearly defines the resource ('the project's Incidents tool configuration') and what it modifies ('privacy defaults and/or the default distribution list'). It effectively distinguishes this mutation tool from the read-only get_project_incidents_configuration sibling.

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: when to use the tool (to update configuration) and important usage guidance such as 'Send only the fields you intend to change; omitted fields keep their current values' and permission requirements for distribution list members. However, it does not explicitly mention alternatives or when not to use this tool, missing the top tier of guidance.

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