ads_module_tools

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

With no annotations, the description carries the full burden of behavioral disclosure. It does not confirm that this is read-only, describe authentication or configuration requirements, explain what happens with an invalid module_id, or indicate the shape of the result.

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 single sentence is front-loaded and free of filler. It is appropriately brief, though it leaves important details to other unfilled fields.

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?

The tool has one required parameter, no annotations, and no output schema, so the description must do more work. It omits how to discover valid module_id values and what the tool returns, which are important for correct invocation.

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 description coverage is 0%, so module_id is completely undocumented in the schema. The description only implies that module_id identifies 'one configured provider MCP module' but gives no format, source, or constraints for obtaining valid module IDs.

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 states a specific verb and resource: discovering tools exposed by a configured provider MCP module. It is clear enough to distinguish discovery from execution, but it does not explicitly contrast with the nearby sibling ads_module_call.

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?

There is no guidance on when to use this tool versus ads_module_call or ads_module_plan. The phrase 'Discover tools' implies a discovery role, but no prerequisites, exclusions, or selection criteria are provided.

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