search_source

Read-onlyIdempotent

Find code patterns in project source files with a bounded regex search. Set file glob and max results to control the scope.

Instructions

Run a bounded regex search across project source files.

TDQS

C2.9/5.0
Behavior2/5

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

Annotations already declare readOnlyHint=true and idempotentHint=true, indicating a safe, read-only operation. The description adds 'bounded' but does not elaborate on behavioral traits beyond what annotations convey, such as how bounds are enforced or what the search scope entails.

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

Conciseness3/5

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

The description is a single sentence, which is concise but overly minimal. It sacrifices essential details for brevity, resulting in a structure that is too terse to be fully useful.

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?

Given the tool has 4 parameters, an output schema, and moderate complexity, the description fails to explain key aspects like the role of 'file_glob', the behavior of 'bounded', or the format of results. The output schema may cover return values, but parameter guidance is severely lacking.

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%, meaning no parameter explanations exist in the schema. The description provides no additional meaning for parameters like 'pattern', 'file_glob', 'timeout_seconds', or 'max_results', leaving the agent without critical usage details.

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

Purpose5/5

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

The description clearly states the action ('Run') and resource ('bounded regex search across project source files'), and it distinguishes from siblings like 'search_output' which targets output instead of source.

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

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description does not explicitly state when to use this tool versus alternatives (e.g., 'search_output'). Usage is implied by the name and context, but no guidance on exclusions or prerequisites is provided.

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