blockbench_open_project

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

No annotations are provided, so the description carries full burden. It states the action ('open') and the result ('new tab for inspection/editing'), but omits side effects, error conditions, permissions, or behavior if the file is already open. This is insufficient for safe invocation.

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?

A single, front-loaded sentence with no unnecessary words. Every part adds value: verb, resource type, source, and purpose.

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 tool with one parameter and no output schema, the description covers the core purpose and parameter context. However, it fails to mention return behavior (e.g., success/error indication) or error handling (e.g., file not found), leaving 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?

With only one parameter (path) and 0% schema description coverage, the description adds some meaning by specifying 'from a local path' and 'uncompressed .bbmodel'. However, it does not clarify path format (absolute/relative) or whether the extension is required, so it only partially compensates.

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 clearly states the verb 'Open', the resource '.bbmodel project', and the context 'from a local path in a new Blockbench project tab for inspection or editing'. This effectively distinguishes it from sibling tools like blockbench_create_rig or blockbench_export_model.

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 implies usage when one wants to inspect or edit an existing .bbmodel file, but it does not explicitly state when not to use it or mention alternative tools. No exclusions or prerequisites are provided, limiting guidance.

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