agent_loop.py:
- Add _truncate_context() with 2-phase strategy (truncate tool results,
then drop oldest middle messages while keeping assistant+tool pairs)
- Add max_context_tokens parameter
- Guard against double-encoded JSON tool arguments (model outputs
string instead of dict)
hermes_base_env.py:
- Wire max_context_tokens=max_token_length through all 3 HermesAgentLoop
construction sites
hermes_parser.py:
- Prevent double-encoding: when arguments are already a string, use as-is
instead of json.dumps() which would double-encode
swe_smith_oracle_env.py:
- Shaped reward structure for cold-start training:
0.0 (no tools) -> 0.05/call up to 0.3 -> 0.4 (install ok) -> 1.0 (tests pass)
- _build_scored_item() override: truncate tokens/masks from END to fit
max_token_len instead of discarding entire groups
All changes are in environments/ only — no effect on TUI/CLI agent loop.
- Updated `.gitignore` to exclude `testlogs` directory.
- Refactored `handle_web_function_call` in `model_tools.py` to support running async functions in existing event loops, improving compatibility with Atropos.
- Introduced a thread pool executor in `agent_loop.py` for running synchronous tool calls that internally use `asyncio.run()`, preventing deadlocks.
- Added `ToolError` class to track tool execution errors, enhancing error reporting during agent loops.
- Updated `wandb_log` method in `hermes_base_env.py` to log tool error statistics for better monitoring.
- Implemented patches in `patches.py` to ensure async-safe operation of tools within Atropos's event loop.
- Enhanced `ToolContext` and `terminal_tool.py` to utilize the new async handling, improving overall tool execution reliability.
- Added new environments for reinforcement learning, including `HermesSweEnv` for software engineering tasks and `TerminalTestEnv` for inline testing.
- Introduced `ToolContext` for unrestricted access to tools during reward computation.
- Updated `.gitignore` to exclude `wandb/` directory.
- Enhanced `README.md` with detailed architecture and usage instructions for Atropos environments.
- Added configuration files for SWE and terminal test environments to streamline setup.
- Removed unnecessary compiled Python files from `__pycache__`.
