Remove unused imports (F401) and duplicate/shadowed import
redefinitions (F811) across the codebase using ruff's safe
autofixes. No behavioral changes -- imports only.
- ~1400 safe autofixes applied across 644 files (net -1072 lines)
- __init__.py re-exports preserved (excluded from F401 removal so
public re-export surfaces stay intact)
- Re-exports that are imported or monkeypatched by tests but look
unused in their defining module are kept with explicit # noqa:
F401 (gateway/run.py load_dotenv; run_agent re-exports from
agent.message_sanitization, agent.context_compressor,
agent.retry_utils, agent.prompt_builder, agent.process_bootstrap,
agent.codex_responses_adapter)
- Unsafe F841 (unused-variable) fixes deliberately skipped -- those
can change behavior when the RHS has side effects
- ruff lints remain disabled in pyproject.toml (only PLW1514 is
selected); this is a one-time cleanup, not a config change
Verification:
- python -m compileall: clean
- pytest --collect-only: all 27161 tests collect (zero import errors)
- core entry points import clean (run_agent, model_tools, cli,
toolsets, hermes_state, batch_runner, gateway)
- static scan: every name any test imports directly from an edited
module still resolves
Add hermes_cli.xai_retirement module that walks a Hermes config and
flags references to models being retired by xAI on May 15, 2026 per
the official migration guide.
Pure logic + dataclass, no I/O — testable in isolation and reusable
from a future hermes migrate xai sub-command.
Mappings (per https://docs.x.ai/developers/migration/may-15-retirement):
- grok-4 / grok-4-0709 -> grok-4.3
- grok-4-fast{,-reasoning,-non-reasoning} -> grok-4.3 (+reasoning_effort=none for non-reasoning)
- grok-4-1-fast{,-reasoning,-non-reasoning} -> grok-4.3 (+reasoning_effort=none for non-reasoning)
- grok-code-fast-1 -> grok-4.3
- grok-imagine-image-pro -> grok-imagine-image-quality
Slots scanned: principal.model, auxiliary.<any>.model (introspective),
delegation.model, tts.xai.model, plugins.image_gen.xai.model. Provider
prefix x-ai/ is normalized.
33 unit tests covering edge cases (empty/non-dict config, valid models,
ambiguous variants, all retired slots, formatter).
