open_in_monodraw

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only says 'Open a file' without explaining side effects, error behavior, or whether the tool requires the Monodraw application to be installed. This leaves the agent unaware of potential issues.

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, concise sentence that earns its place. It wastes no words and is immediately understandable, though it may be too brief for richer guidance.

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 tool's simplicity (one parameter, no output schema) and full schema coverage, the description is minimally adequate. However, it lacks context such as the intended workflow (e.g., opening a diagram file in Monodraw) or any mention of prerequisites. The sibling tools suggest a diagram domain, but the description does not reinforce this.

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 already documents the filePath parameter with a description matching the tool's purpose, so schema coverage is 100%. The description adds no additional parameter semantics, such as path formats, file type constraints, or whether relative paths are supported. Baseline 3 is appropriate.

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 specific action ('Open a file') and a specific application ('Monodraw'), making the tool's purpose unambiguous. It clearly distinguishes itself from sibling tools like export_diagram or list_diagrams, which serve different functions.

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?

There is no guidance about when to use this tool versus the alternatives. It does not mention typical use cases, prerequisites, or situations where another tool would be preferable. The description simply states what the tool does without any contextual advice.

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