C2.9/5.0
Behavior2/5

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

No annotations are provided, so the description carries the full disclosure burden for a destructive operation. It says 'delete' but omits whether the unload is reversible, whether the task/module must be idle, whether mastership is required, and what happens on failure — significant gaps 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.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single compact sentence with the action and target front-loaded; nothing extraneous or padded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a destructive mutation tool with no annotations and no output schema, the description leaves out safety-relevant context such as preconditions, permission/mastership needs, and result reporting. The schema covers inputs, but the behavioral picture an agent needs before deleting a module is incomplete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, with both params documented (task example 'T_ROB1', module name). The description only echoes that a module is removed from a task, adding no format or constraint detail beyond the schema, so baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb ('Unload (delete)') and resource ('a RAPID module') plus the containing scope ('from a task'), which distinguishes it from read-oriented siblings like rws_read_module and rws_get_modules. The 'via RWS' phrasing is mildly redundant but harmless.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No indication of when this should be used versus alternatives such as rws_load_module_from_file, rws_write_module, or whether the module must first be stopped/not executing. No prerequisites such as required mastership are mentioned.

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