create_source

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

With no annotations, the description bears full responsibility for behavioral disclosure. It only indicates a write operation ('Create') without detailing side effects like triggering fetches, duplicate handling, or authorization needs. This is a significant gap for a mutation tool.

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 extremely concise: one line and a parameter list. Every sentence adds value, and it is front-loaded with the purpose. 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?

For a creation tool with no output schema, the description covers the input parameters well but omits details about the return value (e.g., the created source object) and fails to mention any required authentication or permissions, though these are common in API contexts.

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?

Given 0% schema coverage, the description effectively explains each parameter, including the allowed values for source_type and usage of url and query. However, it could be improved by noting conditional requirements (e.g., url required for rss/reddit, query for google).

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 action ('Create a new news source') and the resource, distinguishing it from siblings like update_source or delete_source. However, it could be more precise by explaining what constitutes a 'news source' in this context.

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 such as update_source. The description does not mention any prerequisites or context (e.g., that this is for adding new sources, not modifying existing ones).

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