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

No annotations are provided, so the description carries the full burden. It doesn't disclose whether this is a read-only operation, any required permissions, or potential side effects. While it describes the return value, this is insufficient to understand the tool's behavioral profile.

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 well-structured with a concise first sentence that captures the purpose, followed by a clear Args section and a Returns section. Every line provides useful information without redundancy or fluff.

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 description covers purpose, all parameters, and the return value. However, it lacks information about when to use the tool, any limitations, or behavioral expectations. Given the absence of annotations and output schema, this is a minor gap, but the tool is relatively simple.

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%, but the description compensates well by explaining each parameter in the Args section, including types and intended use (e.g., absolute path for repo_path, comma-separated list for external_modules, format options for output_format). This adds significant value beyond the schema.

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 it analyzes repository importance using the CodeRank algorithm to identify critical modules, providing a specific verb and resource. It distinguishes itself from sibling tools by referencing a specific algorithm, though it doesn't explicitly contrast with similar hotspot analysis tools.

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 when repository importance is needed but gives no explicit guidance on when to use this tool versus alternatives, nor does it mention any exclusions or prerequisites. The context is clear enough for a basic understanding but lacks comparative guidance.

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