Add Collection to Model

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

Annotations indicate this is a write operation (readOnlyHint=false), which matches the description. However, the description adds no behavioral details beyond what the schema provides—e.g., what happens if the collection already exists, permission requirements, or side effects. With annotations present, the bar is lower, but the description still fails to add 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?

Extremely concise: one sentence, 10 words, no fluff. The action and key parameters are front-loaded, making it efficient for an agent to parse.

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 basic operation but omits important context: no return value description, no error conditions, no prerequisites (e.g., collection must exist), and no indication of whether the operation is idempotent (annotation says it is not). For a simple tool with full schema coverage, the description is incomplete.

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%, so baseline is 3. The description merely echoes 'by type and model ID' but does not add new parameter-level insights, examples, or constraints beyond the schema's own descriptions (e.g., type values, ID format).

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 ('Add a collection to a model') and the key identifiers ('by type and model ID'), distinguishing it from sibling tools like transkribus_model_add_collection_by_id which presumably uses only model ID.

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 guidance on when to use this tool vs. alternatives such as transkribus_model_add_collection_by_id or remove tools. The only hint is the inclusion of both type and modelId, but no usage context, prerequisites, or exclusions are provided.

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