color_load_version

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

With no annotations, the description should carry full behavioral disclosure. It clearly states that the operation is destructive ('replacing current'), which is a key behavioral trait. However, it does not explain whether the operation is reversible, what happens to the existing version data, or how remote versions (version_type=1) are handled, leaving some behavioral ambiguity.

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 two sentences, front-loaded with the core action, and includes a useful contrast with a sibling tool. There is no unnecessary filler, making it concise and well-structured.

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 description covers the tool's primary function and key differentiator, and the schema fully documents parameters. While it lacks detail on error conditions or version-type nuances, the combination of schema and brief description is adequate for the tool's complexity, though it could be more comprehensive given the lack of annotations.

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 input schema provides descriptions for all 5 parameters, giving 100% schema coverage. The description itself does not add any parameter-specific information beyond what the schema already documents, so it neither enhances nor detracts from the schema's baseline clarity.

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 a specific action 'Load' with a clear object 'a specific grade version onto a timeline item' and states the effect 'replacing current.' It also distinguishes this tool from set_current_version, making its purpose unambiguous relative to a sibling.

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 explicitly contrasts with set_current_version: 'Unlike set_current_version (which switches), load_version replaces the current grade data with the contents of the named version.' This tells the agent when to choose this tool over the alternative, providing clear usage guidance.

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