WarpGrep search subagent integration

[bhaktatejas922]

Given the existing subagent infrastructure, WarpGrep could plug in as a dedicated search subagent. It runs in an isolated context window, issues 8 parallel grep/read/list calls per turn (up to 4 turns), and returns only file:line-range spans. Keeps search noise out of the main agent's context.

SWE-bench Pro with Opus: 39% fewer input tokens, 26% fewer turns, 10% higher solve rate, 15% cheaper.

OpenAI-compatible endpoint.

I've been looking into this and have a few questions before proposing an implementation plan:

1. No existing subagent infrastructure: The issue mentions "given the existing subagent infrastructure," but I don't see any subagent system in the codebase. The current search tools (search_files using ripgrep, codebase_search using semantic indexing) are standard tool calls, not delegated to a separate agent. Could you clarify what you mean by subagent infrastructure, or is the intent to create this as the first subagent-style integration?

2. Integration point: How should WarpGrep fit into the existing tool landscape?

   • As a replacement/alternative for codebase_search (semantic search)?
   • As a new standalone tool (e.g. warp_grep) that the agent can invoke alongside existing search tools?
   • As an internal implementation detail that transparently replaces how search_files or codebase_search work under the hood?

3. Configuration: WarpGrep requires an API key and endpoint URL. Should this be:

   • A new provider configuration in the API settings?
   • A setting under experimental features?
   • Something else?

4. Scope: The WarpGrep docs show it as an OpenAI-compatible chat completion endpoint that receives search queries and returns file spans. Is the expectation that Roo Code would make HTTP calls to the WarpGrep endpoint during tool execution, or is there a local/SDK component involved?

Please mention @roomote in a comment with answers and I'll put together a concrete implementation plan.
