#!/usr/bin/env python3 """Builder. Processes both specifications handed off by the Agent (agents/agent.md's ===BUILDER-HANDOFF=== block, extracted by worker.py) and direct XMPP messages to builder@ (queued by the same listener.py, pointed at a separate connection/queue). Both land in the same builder-inbox queue. Each job runs its own atomic Codex or Claude Code session -- never resumed -- with an iteration limit (AGENT_BUILDER_ITERATION_LIMIT, see docs/intent/builder-iterationslimit.md); a sender's previous reply is carried into their next job as explicit context text instead, so a handoff can still be followed up on directly. The Builder can converse, plan, and implement changes. Board jobs carry a validated runtime snapshot: Codex uses --sandbox workspace-write, while Claude Code uses the installed builder settings. Both receive one --add-dir per entry in AGENT_BUILDER_WRITABLE_DIRS and cannot commit, push or deploy themselves. They edit files and, when done, mark the response with a ===COMMIT-MESSAGE=== block. This script then commit+pushes to dev for whichever repo(s) actually changed -- since 2026-09-06 with no separate nix eval/build verification beforehand (deliberate simplification for development speed; `nixos-rebuild switch` itself still refuses to activate a config that fails to build) -- and, for nixos-config, queues a persistent deployment request for the separate blunix runner. No SSH, no other host, no separate human approval step anymore. Other repositories deploy via webhook, unaffected. A handoff from anyone but the owner never runs a model right away: it waits in AGENT_BUILDER_START_PENDING_DIR for an explicit `/annehmen ` (or `/ablehnen `) from the owner -- see queue_for_start_approval()/handle_start_pending_command(). This is separate from, and earlier than, the existing post-work `/freigeben`/`/verwerfen` gate in AGENT_BUILDER_PENDING_DIR, which only covers the commit once work is already done.

Du kannst selbst NICHT committen, pushen oder deployen -- eine feste Rechte-Regel verbietet dir `git commit`, `git push`, `sudo`, `nixos-rebuild` und jeden Schreibzugriff unter `.git/` direkt, auch mit Schreibrechten sonst im Repo.
