project_open

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

With no annotations provided, the description carries full burden but omits critical behavioral context: what happens to currently open projects, whether this is destructive/replacing, error handling for missing files, or return value format.

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?

Extremely concise with zero waste; front-loaded purpose statement followed by Args documentation. 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?

Adequate for a single-parameter tool but has clear gaps regarding state management side effects and error conditions that would help sequence this tool correctly in multi-step workflows.

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?

Compensates effectively for 0% schema description coverage by specifying 'Absolute path' (crucial constraint) and '.aup3' format requirement that the schema's 'Path' title alone doesn't convey.

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 uses specific verb 'Open' with clear resource 'Audacity project file (.aup3)', distinguishing it from siblings like project_import_audio (which handles media files) and project_new.

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 .aup3 format specification implicitly guides usage toward existing project files rather than audio imports, but lacks explicit when-to-use guidance versus alternatives like project_new or project_import_audio.

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