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

Given no annotations are provided, the description discloses key behavioral traits: it produces a diff visualization report categorizing changes as Added/Removed/Modified. This is sufficient for an agent to understand the tool's operation.

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 sentence with zero fluff, conveying the core purpose and output format efficiently.

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?

With an output schema present and clear description of the report type, the definition is largely complete. It could benefit from mentioning the tool is read-only, but overall it provides sufficient context for an agent.

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 100%, so the baseline is 3. The description adds minor contextual hints (e.g., 'base (old) project'), but does not significantly improve understanding beyond the schema's own descriptions.

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 action ('compare two projects'), the resource ('projects'), and the output ('diff visualization report with Added/Removed/Modified'). This is specific and distinguishes it from sibling tools like analyze_project or merge_projects.

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 through context (comparing two projects vs. analyzing one or merging), but provides no explicit guidance on when to use this tool versus alternatives such as visualize_project or merge_projects.

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