Gemini doesn't find edit tool

[ssoteloserrano]

Description

An error occurred during a process run by the build agent, which uses the Gemini 2.5 Pro model. The model attempted to call the edit tool, but this tool appears to be unavailable in the agent's environment. This resulted in an "invalid tool" error.

Full Error Message: ⚙ invalid [error=Model tried to call unavailable tool 'edit'. Available tools: invalid, bash, webfetch, glob, grep, list, read, todowrite, todoread, task, architecture_scan, testing_scan, config_scan, playwright_browser_close, playwright_browser_resize, playwright_browser_console_messages, playwright_browser_handle_dialog, playwright_browser_evaluate, playwright_browser_file_upload, playwright_browser_fill_form, playwright_browser_install, playwright_browser_press_key, playwright_browser_type, playwright_browser_navigate, playwright_browser_navigate_back, playwright_browser_network_requests, playwright_browser_take_screenshot, playwright_browser_snapshot, playwright_browser_click, playwright_browser_drag, playwright_browser_hover, playwright_browser_select_option, playwright_browser_tabs, playwright_browser_wait_for., tool=edit]

I wonder if the agent directive to strip tools is messing with the coding agent too?

[rekram1-node]

can u share a session of this happening?

[starcraft66]

@rekram1-node Here's an example of it happening with Claude. I've only seen this happen since I started using oh-my-opencode this morning: https://opncd.ai/share/gxGWfMcs

I realize that this is happening because I'm in plan mode and the agent doesn't seem to be aware of it. I'm guessing that's an issue with the agent's prompt.
