list_build_scenes

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

With no annotations, the description carries the full burden. It clearly indicates a read operation ('list') and specifies the output format ('as JSON'). This is sufficient for a simple tool with no parameters.

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 sentence with no extraneous words. Every part earns its place, making it highly concise.

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?

Given the tool's simplicity (no parameters, no output schema), the description is complete enough. It explains the source ('EditorBuildSettings') and output format ('JSON'). One could argue it could mention that these are the scenes configured for building, but that is implied.

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 schema has 0 parameters and schema coverage is 100%, so baseline is 4. The description does not need to add parameter information. It correctly implies no inputs are required.

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 'List scenes in EditorBuildSettings (build order) as JSON.' It uses a specific verb ('List') and resource ('scenes in EditorBuildSettings'), and the parenthetical 'build order' clarifies the scope, distinguishing it from sibling tools like list_all_scenes which list all scenes in the project.

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 description implies the tool is used to retrieve scenes that are part of the build order, but it does not explicitly state when to use this over alternatives like list_all_scenes or get_scene_summary. No exclusions or alternative tool suggestions are provided.

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