remove_tag

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

With no annotations, the description carries the full burden of behavioral disclosure. It only states the action without mentioning side effects (e.g., whether the tag itself is deleted if no items remain), permissions, idempotency, or error behavior. This is a significant gap for a mutation tool.

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, compact sentence that is front-loaded and easy to parse. It avoids fluff, but could be slightly more structured by including edge-case behavior or parameter hints. It earns its place but is at the minimal end of acceptable.

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 simple tool with two integer parameters and no output schema, this description is adequate but leaves gaps. It does not explain what happens if the association does not exist, whether the operation is reversible, or if special permissions are required. These gaps are more impactful because no annotations are provided.

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 descriptions are tautological ('tag_id parameter', 'item_id parameter'), providing no real semantic value. The description itself does not explain the parameters or their roles. Although the parameter names are self-explanatory, neither the schema nor the description adds meaning beyond the names.

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 'Remove a tag from an item' clearly states the action (remove) and the resource (tag-item association). It is specific enough to distinguish from sibling tools like delete_tag (which removes the tag entirely) or add_tag (which adds the association), though it does not explicitly mention these alternatives.

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?

There is no guidance on when to use this tool versus alternatives such as add_tag, delete_tag, or get_item_tags. The description implies its use for untagging an item, but does not provide context, prerequisites, or exclusions.

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