Core changes:
- Added claw-code/src/token_budget.py for projected prompt size, chat-framing overhead, output reserve, and soft/hard input limits.
- Wired preflight prompt-length validation and auto-compact/context collapse into claw-code/src/agent_runtime.py.
- Extended claw-code/src/compact.py so compaction reports usage back to the runtime.
- Added inspection surfaces in claw-code/src/agent_slash_commands.py and claw-code/src/main.py:
- /token-budget and /budget
- token-budget
- Hardened claw-code/src/tokenizer_runtime.py so arbitrary simple model names fall back cleanly instead of trying a slow Transformers
lookup.
- Exported the new helpers in claw-code/src/__init__.py.
Docs and tracking:
- Updated claw-code/PARITY_CHECKLIST.md to mark prompt-length validation, token-budget calculation, and auto-compact/context collapse as
done.
- Updated claw-code/README.md and claw-code/TESTING_GUIDE.md with the new commands and behavior.
Tests:
- Added claw-code/tests/test_token_budget.py.
- Updated claw-code/tests/test_agent_runtime.py, claw-code/tests/test_agent_slash_commands.py, claw-code/tests/test_main.py, and claw-code/
tests/test_agent_context_usage.py.
