v0.1.1Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states that the tool mutates/saves a scene file, not whether it overwrites the existing file, how newPath behaves beyond the schema's variant hint, or what happens on failure.
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?
One short sentence with no filler or redundant content; the core action is front-loaded. It is appropriately concise, even though it sacrifices detail that is captured in other dimensions.
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?
With no annotations and no output schema, the description should compensate but does not; it omits overwrite behavior, success/failure signaling, and any preconditions. The schema covers parameters, so the tool is not wholly underspecified, but the description alone is insufficient for confident invocation.
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 description coverage is 100%: projectPath and scenePath are described as paths, and newPath is explicitly documented as an optional path for creating variants. The description adds no additional parameter meaning, so the baseline 3 applies.
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 specific verb 'save' with the resource 'scene file,' clearly indicating a persistence operation. It does not explicitly differentiate from create_scene, though 'save changes' implies an existing scene, so it stops short of full sibling distinction.
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 is given on when to use this tool versus create_scene or other scene tools, and no prerequisites or exclusions are provided. The word 'changes' implies use after modifications, but that is not actionable enough to help an agent choose correctly.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
