+# Repository Guidelines
+
+## Project Structure & Module Organization
+- `src/omnibase_core/`: core framework code (core, models, enums, exceptions, utils, validation).
+- `tests/`: unit, integration, and performance suites (`tests/{unit,integration,performance}`; fixtures in `tests/fixtures`).
+- `scripts/validation/`: ONEX validators used by pre-commit and CI.
+- `docs/` and top-level *.md reports: design, standards, and performance notes.
+- `examples/`: runnable examples and reference patterns.
+
+## Build, Test, and Development Commands
+- Setup: `poetry install` (Python 3.12). Optional hooks: `pre-commit install`.
+- Lint/Format: `poetry run ruff check .`, `poetry run black .`, `poetry run isort .`.
+- Type Check: `poetry run mypy --config-file mypy.ini`.
+- Tests: `poetry run pytest -q` (async auto, test paths in `tests/`).
+- Validators: `pre-commit run -a`. Key scripts: `validate_structure.py`, `validate_naming.py`, `validate-no-backward-compatibility.py`, `validate-contracts.py`, `validate-union-usage.py`, `validate-pydantic-patterns.py`, `validate-one-model-per-file.py`, `validate-typing-syntax.py`, `validate-enum-case-consistency.py`.
+- Build: `poetry build`. CLI help (if installed): `poetry run omni-agent --help`.
+
+## Coding Style & Naming Conventions
+- Python: 4-space indent; Black line length 88; isort profile black; Ruff rules per `pyproject.toml`.
+- Typing: strict MyPy; modern syntax (`X | Y`, `list[str]`); no `Dict[str, Any]` in models.
+- Naming: one model per file; files `model_*.py` with classes `Model*`; enums `enum_*.py` with classes `Enum*` (validators enforce).
+- Patterns to avoid: `to_dict/from_dict/*_legacy` methods, manual YAML parsing; rely on Pydantic and provided utilities.
+
+## Testing Guidelines
+- Framework: Pytest (+ pytest-asyncio). Test discovery matches `test_*.py` and `*_test.py`.
+- Structure: unit in `tests/unit`, integration in `tests/integration`, performance in `tests/performance`.
+- Coverage: target ≥85% where practical; include critical paths and error handling.
+- Run full suite locally before PR: `pre-commit run -a && poetry run pytest`.
+
+## Commit & Pull Request Guidelines
+- Commits: Conventional style with clear scope; imperative mood; optional emoji accepted (see `git log`).
+  - Examples: `feat(models): add ModelUserProfile`, `fix(validation): handle __pycache__`, `chore(ci): update hooks`.
+- PRs: include description, linked issues, rationale, test results, and screenshots/logs when relevant. Require green pre-commit, passing tests, and ONEX validators.
+
+## Security & Configuration Tips
+- Never commit secrets; `.env` is ignored. Prefer Poetry extras (`--with full|cli|monitoring|kubernetes`).
+- Use dependency injection and provided validators; do not introduce custom serialization or ad-hoc config loaders.
+
+## Validation Suite Overview
+- Pre-commit runs ONEX checks from `scripts/validation/`. Run individually, for example:
+  - `poetry run python scripts/validation/validate_structure.py . omnibase_core`
+  - `poetry run python scripts/validation/validate-no-backward-compatibility.py --dir src/`
+  - `poetry run python scripts/validation/validate-contracts.py .`
+- Key validators (one-liners):
+  - `validate_structure.py`: Repository layout and required paths.
+  - `validate_naming.py`: File/class naming (Model*/Enum*), casing.
+  - `validate-no-backward-compatibility.py`: Blocks `to_dict/from_dict/*_legacy` patterns.
+  - `validate-contracts.py`: Contract YAML schema and fields (e.g., `node_type`).
+  - `validate-union-usage.py`: Safe Union usage and constraints.
+  - `validate-pydantic-patterns.py`: Enforces approved Pydantic idioms.
+  - `validate-one-model-per-file.py`: Exactly one model per file.
+  - `validate-typing-syntax.py`: Modern typing (`|`, `list[str]`).
+  - `validate-enum-case-consistency.py`: Consistent enum case and values.
+- Address violations before PRs; pre-commit must be green.
+
+- Additional hooks:
+  - `validate-no-manual-yaml.py`: Ban ad-hoc YAML parse/dumps in code.
+  - `validate-dict-any-usage.py`: Flag `Dict[str, Any]` in typed domains.
+  - `validate-no-dict-conversion.py` / `validate-no-dict-methods.py`: Disallow dict conversions and `to_dict/from_dict`.
+  - `validate-string-versions-and-ids.py`: Enforce version/id string patterns.
+  - `audit_optional.py`: Audit Optional usage and nullability.
+  - `validate-generic-patterns.py` / `validate-generic-type-methods.py`: Enforce safe generics and forbid type-bound methods.
+  - `validate-typed-references.py`: Detect typed-reference anti-patterns.
+  - `validate-timestamp-fields.py`: Ensure timestamp fields use approved types.
+  - `validate-onex-error-compliance.py`: Standardize ONEX error models/handling.
+  - `validate-stubbed-functionality.py`: Block stubbed/placeholder implementations.
+  - `validate-elif-limit.py`: Enforce max elif chain length.
+
+## Further Reading
+- `docs/VALIDATION_INTEGRATION_GUIDE.md`: How validators integrate with pre-commit and CI.
+- `STANDARDS_COMPLIANCE.md`: ONEX standards applied in this repo.
+- `OMNI_ECOSYSTEM_STANDARDIZATION_FRAMEWORK.md`: Ecosystem-wide conventions and rationale.

+## Shared Agent References
+- Local knowledge base (for contributors using the agent toolchain):
+  - `~/.claude/agents/AGENT_FRAMEWORK.md` (agent architecture)
