From 5721b312b64ab487572262ee4b02fba5cc3e46af Mon Sep 17 00:00:00 2001 From: nasser1941 <9349840+nasser1941@users.noreply.github.com> Date: Tue, 6 Oct 2026 00:47:03 +0200 Subject: [PATCH] Add JSON output, a Python API and a GitHub Action lcode -p --output json prints one result object (status, answer, tool calls, files changed, usage); --output stream-json prints an event per model step and tool result, then the result. --max-steps and --allowed-tools limit a run, and the exit code says how it ended. Without a person to ask, permission requests are refused. from lcode import Session runs requests from Python: run() returns the same result, stream() yields the events, and approve() decides permission requests. cmd_chat now sets up its agent through the same open_agent(). lcode action, with action.yml, runs lcode as a GitHub Action on a self-hosted runner: it answers @lcode in issues and pull requests from trusted people, commits changes to a new pull request (or the pull request's branch), and can review pull requests. The model can't run git steps itself, and its reply is written after the change is proposed.
