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
25 new tests (all Bedrock API calls mocked, no real AWS creds needed):
tests/hermes_cli/test_bedrock_model_picker.py (20 tests):
- provider_model_ids("bedrock") uses live discovery, returns regional
model IDs, falls back gracefully on empty/exception, resolves all
bedrock aliases (aws, aws-bedrock, amazon-bedrock) to live discovery
- list_authenticated_providers() section 2: bedrock appears with AWS
creds, model list from discover_bedrock_models(), total_models
matches, is_current flag works, absent creds hides bedrock, discovery
failure does not crash, no duplicate entries
- Region routing: botocore profile eu-central-1 yields eu.* model IDs
end-to-end; env var takes priority over botocore profile
- providers.py overlay: exists with correct transport/auth_type, label
is non-empty, all aliases normalize to bedrock
tests/agent/test_bedrock_adapter.py (5 tests):
- resolve_bedrock_region() botocore profile fallback, botocore failure
fallback, us-east-1 hard fallback (with botocore mocked)
