Read-onlyIdempotent

Access Godot class documentation: retrieve class info, search classes, find method details, and explore inheritance hierarchies to get API answers.

Instructions

Query Godot class documentation: get_class_info, search_classes, find_method, get_inheritance.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

  "method": "tools/call",
  "params": {
    "arguments": {
      "action": "<action>"
    },
    "name": "docs"
  }
}

TDQS

B3.3/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is clear. The description adds no further behavioral context such as return format, pagination, or error behavior, which is acceptable given the strong annotation coverage.

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?

The description is a single, front-loaded sentence that immediately conveys the tool's purpose and lists its operation types. Every word earns its place, and there is no redundant or filler content.

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

Completeness3/5

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

For a tool with six parameters and four operation variants, the description is minimal but the schema and annotations fill in critical context. It does not explain return values or distinguish action-specific behaviors, which is a gap given there is no output schema, yet the tool's core purpose is clear enough for simple documentation queries.

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 description coverage is 100%, so the schema fully documents all six parameters. The description only repeats the action names already present in the enum, adding no additional meaning beyond what the input schema provides, thus meeting the baseline of 3.

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?

The description clearly states the tool queries Godot class documentation and lists the four supported actions (get_class_info, search_classes, find_method, get_inheritance). This distinguishes it from sibling tools by naming the specific resource and verb, though it does not elaborate on what each action does individually.

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 guidance is provided on when to use this tool versus alternatives, nor how to choose among the four listed actions. The description does not mention any conditions, prerequisites, or competing tools, leaving the agent to infer usage solely from the action names.

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