getImportedSignatures

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

The description discloses the tool's behavior (resolving imported symbols to type signatures) beyond the readOnlyHint annotation. It could further explain how filePath is used or any limitations, but the core behavioral trait is well-covered.

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 extremely concise with two short sentences, each adding essential information. Purpose and usage are front-loaded with no superfluous words.

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 simple parameters, no output schema, and the readOnlyHint annotation, the description is fully adequate. It tells the agent what the tool does and when to use it, completing the contextual picture.

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 already provides 100% coverage with descriptions for both parameters (filePath, maxImports). The description adds no additional meaning beyond the schema, so it meets the baseline 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 clearly states the verb 'resolve' and the resource 'imported symbols → type signatures', and adds a usage hint. It distinguishes itself from siblings like 'getTypeSignature' and 'getImportTree' by focusing on resolving imported symbols specifically.

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 explicitly advises using the tool before calling unfamiliar functions, providing clear context for when to invoke it. However, it does not exclude any scenarios or mention alternatives, which would push it to a 5.

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