Update Collection Metadata

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

Annotations already indicate the tool is not readOnly, not destructive, idempotent, and open world, which covers basic behavioral traits. The description adds no further context about side effects, authentication needs, rate limits, or what happens to existing metadata. Given annotations exist, a score of 3 is appropriate as the description is not contradictory but adds minimal value.

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 unnecessary words. It is appropriately front-loaded and concise. However, it is so brief that it may sacrifice completeness for brevity.

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 tool has 4 parameters with 100% schema coverage and annotations present, but no output schema. The description does not explain the return value or any side effects (e.g., whether the update is immediate, if it returns the updated metadata). For a mutation tool, this missing context reduces completeness.

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 has 100% parameter description coverage, so the baseline is 3. The description does not add any additional meaning beyond what the schema already provides for each parameter. The fields (collId, title, description, language) are self-explanatory from their names and schema descriptions.

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 clearly states the action ('Update') and the resource ('metadata for a collection'). It is specific and not a tautology. However, it does not distinguish from closely related sibling tools like 'transkribus_coll_modify' or 'transkribus_coll_update_default_tag_defs', which could also update collection metadata.

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 provides no guidance on when to use this tool versus alternatives. There is no mention of prerequisites, when not to use, or which specific use cases this tool addresses. Among many collection siblings, the agent has no context to select this one.

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