create_lab

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

No annotations provided, so full burden on description. States creation but omits behavioral details: is it idempotent? Does it overwrite? What errors occur if path is invalid? No side effects mentioned. Only minimal context beyond parameter list.

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 plus a clean 'Args:' list. Every line is informative and well-structured. No redundant or filler content. Could be slightly more compact if combined, but overall efficient.

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?

Missing context about what 'empty' means in a lab (no nodes/links?), what the return value is (output schema exists but description doesn't clarify), and any prerequisites for the path. Siblings offer related creation tools (add_lab_node, add_lab_network) but no comparative context provided.

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 0%, so description must add value. It provides a path example ('/User1') and notes automatic '.unl' extension for name. Other parameters (version, author, etc.) are only lightly elaborated (e.g., 'free-form version string'). Adds some meaning but not fully compensating for missing 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?

Clearly states 'Create a new (empty) lab.' Uses a specific verb and identifies the resource. Differentiates from siblings like get_lab, edit_lab, delete_lab by focusing on creation.

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 versus alternatives (e.g., add_folder for folders). Lacks prerequisites such as whether the target path must exist or what happens if a lab with the same name exists. No mention of when not to use it.

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