web_search

Search the web using Gemini AI to retrieve answers and relevant source links.

Instructions

Ask Gemini queries with web search context.

Note: This uses Gemini CLI's automatic web search capability.
The model determines when to search based on query context.
Best-effort web search - not guaranteed for every query.

Args:
    query: Search query or question to look up on the web
    directory: Working directory for command execution
    model: Optional model alias (flash, pro, or custom)
    timeout_seconds: Optional per-call timeout override in seconds

Returns:
    Gemini's response with potential web sources

Behavior3/5

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

No annotations provided, so description carries full burden. It mentions automatic web search and best-effort nature, but omits details like rate limits, cost, or potential failure modes. Adequate but not thorough.

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

Conciseness4/5

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

Description is front-loaded with purpose, followed by notes and args in a clear docstring format. Slightly verbose but well-structured; no redundant sentences.

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

Completeness4/5

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

Output schema exists, so return values are covered. Description explains tool behavior, parameters, and limitations. Complete for a web search tool with given complexity.

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

Parameters4/5

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

Schema coverage is 0%, but description adds meaning to all 4 parameters: query as search term, directory as working directory, model as optional alias, timeout as per-call override. This compensates well for missing schema descriptions.

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 tool name 'web_search' and description 'Ask Gemini queries with web search context' clearly state the purpose. It distinguishes from siblings (consult_gemini, consult_gemini_with_files) by explicitly mentioning web search context.

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

Usage Guidelines4/5

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

Description explains that the model determines when to search and that it's best-effort, giving guidance on when to use and expectations. However, it does not explicitly state when not to use or mention alternatives.

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