AI summary

Added agent self‑evaluation, Claude request APIs, accurate world context, and a one‑click shutdown script.

Full changelog

v5.4.0

Three local LLMs with persistent psychological states running on your hardware. See the README for what actually happened when we let them run overnight.

What's new

For agents

  • invoke_claude — agents submit implementation requests to a human with system write access. They design, you decide whether to build.
  • check_claude_status — agents check whether their requests were fulfilled.
  • self_evaluate — agents assess their own work against actual file evidence using their own model.
  • /agentOS/design/ — writable space for agent specs and architectural proposals.
  • Agents now receive accurate world context in every existence prompt (what environment they're actually in, what capabilities actually do). Previously they invented hardware that doesn't exist.
  • Futility stressor now checks whether deployed tools actually get called in subsequent goals, not just whether goals complete.
  • synthesize_capability: 90s dedup guard stops spin loops. Auto-test on deployment surfaces broken code immediately.

Bug fixes

  • autonomy_loop: shell commands that exit 0 with no stdout now count as successful artifacts.
  • fs_write: non-string content auto-coerced to JSON instead of 422.

For users

  • stop.bat — one-click shutdown. Stops containers, clears VRAM. Run launch.bat to resume. State preserved.
  • GPU block in docker-compose.yml documented as optional.
  • config.example.json updated to qwen3.5:9b.

Setup

Download the ZIP, extract anywhere, double-click install.bat. Everything else is automatic.
