  4. First observed

TDQS

C2.9/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds no additional behavioral context such as pagination behavior, limits, or the meaning of 'snapshot' vs 'files'. With annotations covering safety, the description adds minimal extra value.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, efficient sentence with no unnecessary words. It is appropriately front-loaded, stating the core function immediately.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool has 6 parameters, a oneOf constraint, and an output schema, yet the description explains none of these. It does not clarify the difference between 'files' and 'snapshot' inputs, how pagination works, or what the output format is. Given the complexity, the description is severely under-specified.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% and the description does not explain any of the 6 parameters. It does not clarify the roles of 'files', 'snapshot', 'symbol', 'limit', 'offset', or 'compact'. The description's mention of 'supplied files' and 'target file' vaguely maps to 'files' and 'symbol', but this is insufficient given the oneOf requirement and pagination parameters.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb ('Return') and resource ('supplied files') with a clear condition ('statically import one target file'). It distinguishes from siblings like find_references by focusing on file-to-file import relationships. However, the required parameter is named 'symbol' while the description refers to a 'target file', creating ambiguity about whether 'symbol' is a file path or a code symbol.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

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 like get_imports or find_references. The description does not mention any exclusions, prerequisites, or typical scenarios. The agent is left to infer usage from the name and description.

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