📄 Description

  • LocalContextMiddleware: Adds runtime version detection (Python, Node) and git dirty file count to the environment context injected into agent conversations
  • LoopDetectionMiddleware: New proposal file (NOT wired in) that detects when the agent is stuck editing the same file repeatedly
    • Soft warning at 4 edits: appends a nudge to the tool output suggesting a different approach
    • Hard warning at 8 edits: injects a HumanMessage forcing the agent to stop and ask the user for help
    • Counters reset automatically on summarization (detected via message count drop) and on /clear or new threads (new middleware instance)

The loop detection middleware is ported from the Harbor benchmark harness where it ran across 445 TB2 trials, adapted for CLI's human-in-the-loop context.
