create_bin

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

No annotations are provided, so the description carries the full burden. It mentions 'confirm it exists,' which indicates a post-creation verification, but it does not disclose what happens on failure, whether duplicate names are allowed, or any permissions required. For a mutation tool, this is insufficient behavioral detail.

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 concise sentence with no redundant wording. It clearly and efficiently communicates the tool's action and the confirmation step.

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 one parameter and no output schema, the description covers the core action and verification. However, it does not explain the return value or behavior when the bin already exists, which leaves some context gaps. It is adequate but not fully complete.

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 fully describes the only parameter 'name' (with description 'Bin name'), achieving 100% schema description coverage. The tool description adds no additional parameter semantics beyond the schema, so the baseline score of 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 clearly states the tool's function: 'Create a bin in the project panel and confirm it exists.' It uses a specific verb ('create'), identifies the resource ('bin in the project panel'), and adds a verification step. This distinguishes it from sibling tools like 'create_sequence_from_items'.

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 implies the usage (when you need to create a bin) but does not provide explicit guidance on when to use it vs alternatives or any exclusions. There are no directly competing sibling tools, so reliance on the name and description is acceptable, but still lacks formal guidance.

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