get_module_schema

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

No annotations are provided, so the description must carry the full burden of behavioral disclosure. It mentions 'slim' and 'when catalog has it,' but fails to specify what happens when the module is missing from the catalog (e.g., error, empty result) or what 'slim' entails. This leaves the agent uncertain about failure modes.

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 concise sentence with no filler. Every term adds meaning, including 'slim' and 'when catalog has it,' making it efficiently front-loaded and appropriately sized.

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 is simple with one parameter and has an output schema, so return values are presumably covered. However, the description lacks guidance on missing-module behavior and does not situate this tool relative to siblings like search_modules, leaving practical edge cases unaddressed.

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 input schema provides only a 'module' string with no description (0% coverage). The description adds critical semantic meaning by specifying that the parameter expects a module FQCN (fully qualified class name), clarifying the required input format beyond the raw 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 uses the clear verb 'Return' and specifies the resource: 'slim arg schema for a module FQCN'. This distinguishes it from sibling tools like search_modules and run_module, making its purpose unambiguous.

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 phrase 'when catalog has it' implies a conditional context but does not explicitly contrast with alternatives like search_modules. There is no explicit when-to-use or when-not-to-use guidance, though the intended usage is somewhat inferable from sibling names.

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