Remove dead code: toolFormat field in getEnvironmentDetails

[hannesrudolph]

Summary

The toolFormat = "native" field in getEnvironmentDetails.ts is dead code and should be removed. We no longer need to tell models about the tool format since native tool calling is the only protocol we support (XML-based tool calling has been retired).

Location

src/core/environment/getEnvironmentDetails.ts

Current Code

const toolFormat = "native"

details += `\n\n# Current Mode\n`
details += `<slug>${currentMode}</slug>\n`
details += `<name>${modeDetails.name}</name>\n`
details += `<model>${modelId}</model>\n`
details += `<tool_format>${toolFormat}</tool_format>\n`

Suggested Action

Remove the toolFormat constant and the <tool_format> line from the environment details output.

I've analyzed this issue and here's my proposed implementation plan:

1. In src/core/environment/getEnvironmentDetails.ts, remove line 224: const toolFormat = "native"
2. Remove line 230: details += \<tool_format>${toolFormat}</tool_format>\n``

Verification:

• Confirmed toolFormat is only used in this file (lines 224 and 230)
• No tests reference tool_format, so no test updates needed
• This is a safe dead code removal since native tool calling is now the only supported protocol

Please mention @roomote in a comment saying that you approve this plan, and I'll proceed with the implementation.

@roomote approved.

I've seen the approval and will proceed with the implementation. I'll open a PR to share progress.
