engine_static_dir_add

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

With no annotations, the description carries the behavioral burden. It discloses that the operation creates a folder and that the parent must already exist, which is meaningful. However, it does not state what happens if the folder already exists, whether creation is recursive, or any error behavior, leaving gaps for a write operation.

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?

Two short sentences with no filler. The action is stated first and the essential path constraint follows immediately; every word earns its place.

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 one-parameter folder-creation tool, the description provides the core information needed to call it: what it does and what the path must satisfy. It lacks conflict/error behavior and explicit sibling routing, but the low complexity means these are minor rather than blocking gaps.

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 schema provides only a string type with no description, so the description must compensate. It explains that 'path' is the whole new folder and that its parent must exist, which directly clarifies the required input beyond 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?

The description states a clear action ('Create') and resource ('a statics folder'), so an agent knows this tool creates a directory rather than a file. It is distinguishable from sibling rename/remove tools by the verb and from static_add by the word 'folder', though it does not explicitly name alternatives.

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 verb 'Create' implies when to use this tool: when a new statics folder is needed. It also provides a useful prerequisite, that the parent directory must exist, but it gives no explicit guidance on alternatives or exclusions relative to sibling directory tools.

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