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

Annotations already establish that this is a non-read-only but non-destructive, closed-world operation, so the bar is lower. The description still earns credit by disclosing the naming scheme, that non-target slots stay as chosen, and that each resulting variant is a plain project with no takes — meaningful output-shape information.

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?

Three tight sentences that lead with the action and naming before the downstream export hint and the output shape. No filler, though the parenthetical placement slightly interrupts the flow.

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 three-parameter creation tool with no output schema, it covers what gets created, how it is named, what is left unchanged, and the next step. The only notable gap is whether it returns the new project identifiers or requires an open project in the response.

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 67%, with takeIds and projectId already documented in the schema. The phrase 'for each take of a slot' clarifies that slotId selects the slot whose takes are multiplied, but it adds no syntax or ID-format detail beyond what the schema supplies.

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 verb and resource: it creates one variant project per take of a slot, with a naming pattern. It is distinguishable in substance from create_variants and create_language_variants, though it never names those siblings, so the agent must infer the boundary.

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?

Adds useful context that takes make one-variable tests and points to export_projects as the follow-up step. It gives no explicit when-not guidance and never explains how this differs from create_variants or create_language_variants, which are the most likely near-miss choices.

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