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

With no annotations, the description carries full burden for behavioral disclosure. It states the tool projects blast radius and historical outcomes, implying analysis without side effects, but it does not confirm read-only behavior, specify required permissions, or describe the output format. Important behavioral traits are omitted.

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 8-word sentence, which is highly concise, but at the expense of necessary detail. For a tool with two parameters and no other documentation, it is underspecified and does not earn its brevity.

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?

Given the absence of annotations, output schema, and parameter descriptions, the description is critically incomplete. It fails to provide essential context about inputs, outputs, or tool behavior, making it difficult for an agent to use effectively.

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%, meaning the description provides no information about the two parameters (file_path and change_description). The agent is left without any guidance on how to specify these inputs or what values are expected, severely hindering correct invocation.

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 'Project' and identifies the resource as 'blast radius and historical outcomes', clearly indicating the tool's purpose of assessing impact of a proposed change. However, it doesn't explicitly distinguish from siblings like 'predict_regression' or 'validate_change', which could also involve outcomes.

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?

No guidance is provided on when to use this tool versus alternatives. The sibling tools include 'validate_change' and 'predict_regression', which may serve similar or complementary roles. The description lacks any context about appropriate use cases, prerequisites, or exclusions.

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