create_collection

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

No annotations exist, so the description bears the full burden of disclosing behavior. It states the core creation action and nesting, but does not say what happens when parent does not exist, whether duplicate names are rejected, or whether creation is otherwise validated. This is minimal transparency for a mutating 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?

One sentence, eight words, action front-loaded and every phrase adds value. No redundant restatement of the schema.

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 two-parameter creation tool this is mostly sufficient, but with no annotations and no output schema it remains thin on error cases, prerequisites (parent must exist), and behavior on duplicate names. The core operation is clear, yet an agent is left guessing at failure behavior.

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 coverage is 0%, so the description must carry parameter meaning. It does clarify the parent behavior ('optionally nested inside another'), which maps to the parent parameter, but leaves name semantics and any constraints entirely to inference from the schema.

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?

States a specific action ('Create') on a specific resource ('collection') and adds the optional nesting scope. This clearly separates it from siblings like list_collections (listing) and move_to_collection (moving existing objects/collections).

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?

Gives no guidance on when to use this tool instead of alternatives such as move_to_collection or list_collections, and no prerequisites are mentioned. The only hint is that nesting is optional, but no if/then routing is provided.

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