inspect_local_workbook

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

With no annotations, the description states safety and read-only nature but omits exactly what 'contents' means (e.g., file list vs metadata) and error behavior. Adequate but minimal.

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?

Two sentences front-load the purpose and behavior, with zero waste. Ideal conciseness for a simple tool.

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?

No output schema exists, yet the description does not explain the return format or data. For a read-only inspection tool, the output is a critical missing piece.

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?

Schema covers 100% of parameters with clear description ('Absolute .twbx path'). The tool description adds no extra parameter meaning beyond the schema, so 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 clearly identifies the resource (local .twbx archive) and action (inspect contents), with 'Read-only' distinguishing it from mutation tools like build_workbook or publish_to_tableau_public.

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?

'Safely inspect' and 'Read-only' imply usage for examining archives without modification. No explicit alternatives or exclusions, but the context from siblings makes the intended use clear.

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