color_add_version

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

Annotations are absent, so the description carries the full burden. It only states the action without disclosing side effects (e.g., whether the new version becomes active, name uniqueness requirements, or effects on existing versions). The word 'local' adds a small constraint, but this remains a thin mutation description.

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?

A single, front-loaded sentence communicates the operation in 11 words. No filler or duplication of schema details; it earns its place.

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?

For a relatively simple create operation, the combination of complete schema descriptions and an output schema makes the minimal description workable. However, it omits usage context (current timeline, version management workflow) that would help an agent choose correctly among the many color_version sibling tools.

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% and all four parameters (item_name, track_type, track_index, version_name) have meaningful schema descriptions. The tool description itself adds no parameter-specific meaning, but the schema fully compensates, so baseline 3 is appropriate.

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 verb ('Create') and identifies the exact resource ('new local grade version on a timeline item'). It clearly distinguishes from sibling version tools such as color_load_version or color_delete_version by specifying it creates a new local version on an item.

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 explicit when/when-not or alternatives are given. The phrase 'on a timeline item' implies it is for adding a version to an existing item, and sibling tools define the surrounding version workflow, but the description does not state when to prefer this over color_load_version or color_get_versions.

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