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

No annotations provided, and the description does not disclose behavioral traits such as side effects (e.g., altering internal state), error handling, blocking behavior, or execution limits. For a script execution tool, more transparency is needed.

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 brief, includes an example, lists aliases, and specifies constraints. Every sentence adds value without redundancy.

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?

Given the simple input schema and presence of an output schema (not shown), the description is largely complete. It covers file type, existence requirement, and aliases. Could mention return value or execution behavior, but output schema likely covers that.

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?

With 0% schema coverage, the description adds crucial meaning: the 'path' parameter must point to a local file with .cxc or .py extension. The example further clarifies usage. This compensates for the bare 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?

Clearly states the tool runs ChimeraX command scripts (.cxc) or Python scripts (.py), with specific verbs and resource types. Distinguishes from sibling tools that perform specific actions like minimizing energy or opening structures.

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?

Indicates file must exist locally with .cxc or .py extension and gives an example, but lacks explicit guidance on when to use this tool vs. other tools for specific operations. Does not mention alternatives or use-case exclusions.

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