project.open

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

No annotations are provided, so the description must carry the full burden of behavioral disclosure. 'Open project' is a potentially major action (loading state, possibly affecting undo history or cached data), but the description reveals no side effects, permissions, or state changes beyond the implied 'open' action.

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?

At only two words, the description is extremely brief but not effectively concise—it sacrifices necessary detail. A concise description would front-load the purpose while adding minimal but critical context (e.g., 'Open an existing Binary Ninja project by path'). Current form is under-specified.

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 lack of annotations, no output schema, and the potentially complex operation of opening a project (involving file I/O, state initialization, errors), the description is completely inadequate. It fails to explain return values, failure modes, or what resources are loaded, leaving the agent to guess or fail.

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?

There is one parameter (path) with 0% schema description coverage. The description does not clarify what the path parameter expects (e.g., file path, URL, file system path format, required protocol). The input schema only specifies it as a required string, leaving the agent with no semantic guidance.

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 'Open project.' uses a clear verb+resource structure. It distinguishes the tool from sibling tools like project.create, project.close, and project.list, indicating the action of opening rather than creating or listing. However, it lacks detail on what 'open' entails (e.g., loading a project into the current context).

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 description provides no guidance on when to use this tool versus alternatives like session.open or project.create. It does not state prerequisites (e.g., the project must exist) or offer exclusions. The agent is left to infer usage context from the name alone.

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