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

With no annotations, the description carries the full burden. It adds the behavioral constraint of being called first, but does not disclose potential side effects (e.g., overwriting previous directory, requiring permissions, or return behavior). The minimal behavioral info is adequate for a simple initialization tool but lacks depth.

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 two sentences, no wasted words, and front-loaded with purpose. Every sentence earns its place, efficiently conveying the core function and a critical usage constraint.

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 1-parameter tool with an output schema (not shown), the description covers the essential function and ordering constraint. It lacks detail on return values or error handling, but assuming the output schema fills that gap, the description is nearly complete.

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 description coverage is 0% for the single parameter 'path'. The description implies path is a directory path for the project, but adds no details on format, absolute/relative, or validation rules. This adds minimal meaning beyond the schema's structure.

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 'Set patent project directory' with a specific verb and resource. It also distinguishes from sibling tools by declaring it as a prerequisite, positioning it uniquely as the setup tool.

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?

Explicitly says 'Must be called before any other tool', providing clear guidance on when to use it. This establishes a strict ordering rule that distinguishes its usage from all sibling tools.

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