create_module

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

Annotations confirm non-read-only and non-destructive behavior, which aligns with 'create' but the description adds no additional behavioral context (e.g., whether it modifies the current model state, permissions needed, or side effects). Minimal value beyond 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?

Single sentence, no unnecessary words. Front-loaded with action and resource. Every phrase earns its place.

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 3 parameters and no output schema. The description covers the core purpose, but lacks explanation of how 'members' are used or whether the module is scoped to a specific model. Adequate but not thorough.

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%, so the description does not need to compensate. It adds no parameter-specific meaning beyond the schema, earning the baseline score of 3.

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 tool creates a 'logical module/group for organizing variables,' specifying the action (create), resource (module/group), and purpose (organizing variables). It distinguishes from siblings like 'add_to_module' (which modifies existing) and 'delete_module'.

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 siblings such as 'add_to_module', 'rename_module', or 'create_model'. The description does not mention prerequisites, context, or alternatives.

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