compare_work_to_prd

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

No annotations are provided, so the description must disclose behavioral traits. It implies a read-only comparison but does not explicitly state whether it modifies anything, how it locates the PRD, what 'current project context' means, or any limitations. This is a significant transparency gap.

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 entire description is one clear, front-loaded sentence with no filler. Every word contributes to the tool's purpose, making it efficient and easy to scan.

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?

The tool has a simple optional parameter and an output schema, so return values are covered. However, the description lacks behavioral details and usage context, such as what 'current project context' includes or whether this is a safe read operation, leaving some gaps for a moderately complex comparison tool.

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?

The input schema has full 100% coverage for the single 'path' parameter, including its default and description. The tool description adds no parameter-specific information, so the schema does the heavy lifting, warranting the baseline score of 3.

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 uses a specific verb ('compare') with clear resources ('current project context and tasks' vs 'PRD requirements') and states the purpose ('check alignment'). It is distinct from sibling tools like verify_requirements or verify_work by focusing on comparing work against the PRD.

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 gives no guidance on when to use this tool versus alternatives, nor does it mention exclusions or prerequisites. It only states what the tool does, leaving the agent to infer usage from the name and sibling context.

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