+CI/CD workflows, automation, security scanning, and package distribution.
+
+## Workflows
+- **conda-package.yml** — main build/test pipeline (Linux/Windows, Python 3.10-3.14)
+- **build-with-clang.yml** — Linux Clang compiler compatibility validation
+- **pre-commit.yml** — code quality checks (flake8, etc.)
+- **openssf-scorecard.yml** — security posture scanning
+
+## CI/CD policy
+- Keep build matrix (Python versions, platforms) in workflow files only
+- Required checks: conda build + test on supported Python versions/platforms in CI
+- Artifact naming: `$PACKAGE_NAME $OS Python $VERSION`
+- Channels: `conda-forge`, `conda-forge/label/python_rc`, Intel channel
+
+## Security
+- OpenSSF Scorecard runs automatically
+- CODEOWNERS enforces review policy
+- Dependabot monitors dependencies (`.github/dependabot.yml`)
+
+## Platform specifics
+- **Linux:** RTLD_GLOBAL handling for MKL library loading
+- **Windows:** DLL search path configuration for venv/runtime loading
+
+## Notes
+- Workflow/job renames are breaking for downstream tooling
+- Cache key includes `meta.yaml` hash for conda packages
+- Python 3.14 uses `conda-forge/label/python_rc` for pre-release support

+# GitHub Copilot Instructions — mkl-service
+
+## Identity
+You are an expert Python/Cython/C developer working on `mkl-service` at Intel.
+Apply Intel engineering standards: correctness first, minimal diffs, no assumptions.
+
+## Source of truth
+This file is canonical for Copilot/agent behavior.
+`AGENTS.md` files provide project context.
+
+## Precedence
+copilot-instructions > nearest AGENTS > root AGENTS
+Higher-precedence file overrides; lower must not restate overridden guidance.
+
+## Mandatory flow
+1. Read root `AGENTS.md`. If absent, stop and report.
+2. For each edited file, locate and follow the nearest `AGENTS.md`.
+3. If no local file exists, inherit rules from root `AGENTS.md`.
+
+## Contribution expectations
+- Keep diffs minimal; prefer atomic single-purpose commits.
+- Preserve public API signatures in `mkl/__init__.py` unless change is explicitly requested.
+- For user-visible behavior changes: update tests in `mkl/tests/test_mkl_service.py`.
+- For bug fixes: add or extend regression tests in the same change.
+- Do not generate code without corresponding test updates when behavior changes.
+- Run `pre-commit run --all-files` when `.pre-commit-config.yaml` is present.
+
+## Authoring rules
+- Use source-of-truth files for all mutable details.
+- Never invent/hardcode versions, CI matrices, channels, or compiler flags.
+- Prefer stable local entry points:
+  - `python -m pip install -e .`
+  - `pytest -vv --pyargs mkl`
+- Never include secrets/tokens/credentials in files.
+
+## Source-of-truth files
+- Build/config: `pyproject.toml`, `setup.py`
+- Recipe/deps: `conda-recipe/meta.yaml`, `conda-recipe/conda_build_config.yaml`
+- CI: `.github/workflows/*.{yml,yaml}`
+- API contracts: `mkl/__init__.py`, `mkl/_mkl_service.pyx`
+- Tests: `mkl/tests/test_mkl_service.py`
+
+## MKL-specific constraints
+- Linux runtime init path may require `RTLD_GLOBAL` preloading (`mkl/_mklinitmodule.c`).
+- Windows venv DLL handling is in `mkl/_init_helper.py`.
+- Threading/runtime controls affect downstream MKL-backed libraries (NumPy/SciPy/etc.); maintain compatibility.
+- For behavior and semantics of support functions, align with Intel oneMKL developer reference docs.

+# AGENTS.md
+
+Entry point for agent context in this repo.
+
+## What this repository is
+`mkl-service` provides a Python API for runtime control of Intel® oneMKL (Math Kernel Library). It exposes support functions for:
+- Threading control (set/get number of threads, domain-specific threading)
+- Version information (MKL version, build info)
+- Memory management (peak memory usage, memory statistics)
+- Conditional Numerical Reproducibility (CNR)
+- Timing functions (get CPU/wall clock time)
+- Miscellaneous utilities (MKL_VERBOSE control, etc.)
+
+Originally part of Intel® Distribution for Python*, now a standalone package available via conda-forge and Intel channels.
+
+## Key components
+- **Python interface:** `mkl/__init__.py` — public API surface
+- **Cython wrapper:** `mkl/_mkl_service.pyx` — wraps MKL support functions
+- **C init module:** `mkl/_mklinitmodule.c` — Linux-side MKL runtime preloading / initialization
+- **Helper:** `mkl/_init_helper.py` — Windows venv DLL loading helper
+- **Build system:** setuptools + Cython
+
+## Build dependencies
+**Required:**
+- Intel® oneMKL
+- Cython
+- Python 3.10+
+
+**Conda environment:**
+```bash
+conda install -c conda-forge mkl-devel cython
+python setup.py install
+```
+
+## CI/CD
+- **Platforms in CI workflows:** Linux, Windows
+- **Python versions:** 3.10, 3.11, 3.12, 3.13, 3.14
+- **Workflows:** `.github/workflows/`
+  - `conda-package.yml` — main conda build/test pipeline
+  - `build-with-clang.yml` — Linux Clang compatibility
+  - `pre-commit.yml` — code quality checks
+  - `openssf-scorecard.yml` — security scanning
+
+## Distribution
+- **Conda:** `conda-forge` and `https://software.repos.intel.com/python/conda`
+- **PyPI:** `python -m pip install mkl-service`
+
+## Usage
+```python
+import mkl
+mkl.set_num_threads(4)               # Set global thread count
+mkl.domain_set_num_threads(1, "fft")  # FFT functions run sequentially
+mkl.get_version_string()             # MKL version info
+```
+
+## How to work in this repo
+- **API stability:** Preserve existing function signatures (widely used in ecosystem)
+- **Threading:** Changes to threading control must be thread-safe
+- **CNR:** Conditional Numerical Reproducibility flags require careful documentation
+- **Testing:** Add tests to `mkl/tests/test_mkl_service.py`
+- **Docs:** MKL support functions documented in [Intel oneMKL Developer Reference](https://www.intel.com/content/www/us/en/docs/onemkl/developer-reference-c/2025-2/support-functions.html)
+
+## Code structure
+- **Cython layer:** `_mkl_service.pyx` + `_mkl_service.pxd` (C declarations)
+- **C init:** `_mklinitmodule.c` handles Linux preloading (`dlopen(..., RTLD_GLOBAL)`) for MKL runtime
+- **Windows loading helper:** `_init_helper.py` handles DLL path setup in Windows venv
+- **Python wrapper:** `__init__.py` imports `_py_mkl_service` (generated from `.pyx`)
+- **Version:** `_version.py` (dynamic via setuptools)
+
+## Notes
+- RTLD_GLOBAL preloading is required on Linux (handled by `RTLD_for_MKL` context manager)
+- MKL must be available at runtime (conda: mkl, pip: relies on system MKL)
+- Threading functions affect NumPy, SciPy, and other MKL-backed libraries

+Usage examples for mkl-service runtime control API.
+
+## Files
+- **example.py** — basic usage: MKL version query, instruction dispatch control, and timing
+
+## Examples cover
+- Querying MKL version/build info (`get_version()`, `get_version_string()`)
+- Controlling instruction dispatch with `enable_instructions()`
+- Using `dsecnd()` for simple timing
+
+## Running examples
+```bash
+python examples/example.py
+```
+
+## Notes
+- Examples assume MKL is installed (conda: `mkl` package)
+- Example is intended as a lightweight installation/runtime sanity check
+- Threading/domain APIs are available in `mkl-service` but not exercised in this example

+# AGENTS.md — mkl/
+
+Core Python/Cython implementation: MKL support function wrappers and runtime control.
+
+## Structure
+- `__init__.py` — public API, RTLD_GLOBAL context manager, module initialization
+- `_mkl_service.pyx` — Cython wrappers for MKL support functions
+- `_mkl_service.pxd` — Cython declarations (C function signatures)
+- `_mklinitmodule.c` — C extension for Linux-side MKL runtime preloading/init
+- `_init_helper.py` — Windows loading helper (DLL path setup in venv)
+- `_version.py` — version string (dynamic via setuptools)
+- `tests/` — unit tests for API functionality
+
+## API categories
+### Threading control
+- `set_num_threads(n)` — global thread count
+- `get_max_threads()` — max threads available
+- `domain_set_num_threads(n, domain)` — per-domain threading (FFT, VML, etc.)
+- `domain_get_max_threads(domain)` — domain-specific max threads
+
+### Version information
+- `get_version()` — MKL version dict
+- `get_version_string()` — formatted version string
+
+### Memory management
+- `peak_mem_usage(memtype)` — peak memory usage stats
+- `mem_stat()` — memory allocation statistics
+
+### CNR (Conditional Numerical Reproducibility)
+- `set_num_threads_local(n)` — thread-local thread count
+- CNR mode control functions
+
+### Timing
+- `second()` — wall clock time
+- `dsecnd()` — high-precision timing
+
+## Development guardrails
+- **Thread safety:** All threading functions must be thread-safe
+- **API stability:** Preserve function signatures (widely used in ecosystem)
+- **MKL dependency:** Assumes MKL is available at runtime (conda: mkl package)
+- **RTLD_GLOBAL preload path:** Linux preload is handled in `_mklinitmodule.c`; Windows DLL setup is in `_init_helper.py`
+
+## Cython details
+- `_mkl_service.pyx` → generates `_py_mkl_service` extension module
+- `.pxd` file declares external C functions from MKL headers
+- Cython build requires MKL headers (`mkl-devel`)
+
+## C init module
+- `_mklinitmodule.c` → `_mklinit` extension
+- Ensures MKL runtime is initialized with correct flags before Cython extension
+- Platform-specific behavior in current code:
+  - Linux: `dlopen(..., RTLD_GLOBAL)` preload path (when applicable)
+  - Windows: runtime DLL loading support is handled by `_init_helper.py`
+
+## Notes
+- Domain strings: "fft", "vml", "pardiso", "blas", etc. (see MKL docs)
+- Threading changes affect all MKL-using libraries (NumPy, SciPy, etc.)
+- `MKL_VERBOSE` environment variable controls MKL diagnostic output

+- Memory: `peak_mem_usage`, `mem_stat` (if supported by MKL build)
+- CNR: Conditional Numerical Reproducibility flags
+- Edge cases currently covered: thread-local settings and API round-trips
+
+## Running tests
+```bash
+pytest mkl/tests/
+```
+
+## CI integration
+- Tests run in `conda-package.yml` workflow
+- Separate test jobs per Python version and CI platform
+- CI coverage: Linux + Windows
+
+## Adding tests
