Subject: [PATCH 1/7] refactor: Make workflows reusable for external
 repositories

This change refactors the GitHub Actions workflows to support 'workflow_call' triggers.

Key changes:
- Added 'workflow_call' triggers to all relevant workflows.
- Replaced hardcoded 'phlex' references with dynamic repository information.
- Added inputs to configure checkout paths, build matrices, and skip relevance checks.
- Ensured workflows remain backward-compatible with existing triggers.

This allows the workflows to be called from external repositories, improving their reusability and portability.

Subject: [PATCH 2/7] refactor: Make workflows reusable for external
 repositories

This change refactors the GitHub Actions workflows to support 'workflow_call' triggers.

Key changes:
- Added 'workflow_call' triggers to all relevant workflows.
- Replaced hardcoded 'phlex' references with dynamic repository information.
- Added inputs to configure checkout paths, build matrices, and skip relevance checks.
- Ensured workflows remain backward-compatible with existing triggers.
- Fixed an issue with constructing CMake sanitizer options by correctly extracting the repository name.
- Corrected the relevance check in `actionlint-check.yaml` to handle pull request context from `workflow_call`.

This allows the workflows to be called from external repositories, improving their reusability and portability.

Subject: [PATCH 3/7] refactor: Make workflows reusable for external
 repositories

This change refactors the GitHub Actions workflows to support 'workflow_call' triggers, making them self-contained and portable for use in external repositories.

Key changes:
- Added 'workflow_call' triggers to all relevant workflows with inputs to configure behavior like checkout paths, build matrices, and relevance check skipping.
- Replaced hardcoded 'phlex' references with dynamic repository information.
- Ensured workflows remain backward-compatible with existing triggers.
- Fixed an issue with constructing CMake sanitizer options by correctly extracting the repository name from the full 'owner/repo' string.
- Corrected the relevance check in `actionlint-check.yaml` to handle pull request context from `workflow_call`.
- Updated workflows to explicitly check out the 'phlex' repository for ancillary scripts or to use canonical remote paths for reusable actions, ensuring they are self-contained.

Subject: [PATCH 4/7] docs: Correct bot command example for forks

Corrects the example bot command in the reusable workflows guide for contributors working on a fork of the repository.

The previous example, `@your-github-usernamebot format`, was incorrect. The correct command is `@phlexbot format`, as the dynamic repository name in the workflow resolves to `phlex` even in a fork.

+# Using Reusable Workflows from the Phlex Repository
+
+This guide explains how to integrate the reusable GitHub Actions workflows from the `Framework-R-D/phlex` repository into your own project.
+
+### Prerequisites
+
+#### Personal Access Token (PAT)
+
+For workflows that automatically commit fixes to pull requests (e.g., formatters), you must create a Personal Access Token (PAT) and add it as a secret to your repository.
+
+1.  **Create a PAT:** Follow the GitHub documentation to [create a fine-grained personal access token](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/managing-your-personal-access-tokens#creating-a-fine-grained-personal-access-token).
+    *   Give it a descriptive name (e.g., `WORKFLOW_FIXES_PAT`).
+    *   Grant it the following repository permissions:
+        *   `Contents`: `Read and write`
+        *   `Pull requests`: `Read and write`
+2.  **Add the PAT as a Repository Secret:**
+    *   In your repository, go to `Settings` > `Secrets and variables` > `Actions`.
+    *   Create a new repository secret named `WORKFLOW_PAT` and paste your PAT as the value.
+
+### Calling a Reusable Workflow
+
+To use a workflow, you call it from a workflow file in your own repository's `.github/workflows/` directory. The basic syntax is:
+
+```yaml
+jobs:
+  some_job:
+    uses: Framework-R-D/phlex/.github/workflows/<workflow_file_name>.yaml@main
+    with:
+      # ... inputs for the workflow ...
+    secrets:
+      WORKFLOW_PAT: ${{ secrets.WORKFLOW_PAT }}
+```
+
+**Note:** Always reference the workflows using the `@main` ref to ensure you are using the latest stable version.
+
+---
+
+### For Contributors Working on a Fork of Phlex
+
+If you are developing on a fork of `Framework-R-D/phlex` itself, the CI/CD workflows will run automatically on your pull requests within the fork, just as they do on the main repository. You do not need to use the `uses:` syntax described below.
+
+However, to enable the automatic fixing features (e.g., for `cmake-format-fix` or `python-fix`), you will need to perform two steps:
+
+1.  **Enable Workflows:** By default, GitHub Actions are disabled on forks. You must manually enable them by going to the `Actions` tab of your forked repository and clicking the "I understand my workflows, go ahead and enable them" button.
+2.  **Create the `WORKFLOW_PAT` Secret:** The auto-fix workflows require a Personal Access Token (PAT) with write permissions to commit changes back to your PR branch. Follow the instructions in the "Prerequisites" section above to create a PAT and add it as a secret named `WORKFLOW_PAT` **to your forked repository's settings**.
+
+Once you have done this, you can trigger the auto-fix workflows by commenting on a pull request in your fork (e.g., `@phlexbot format`).
+
+---
+
+### Available Workflows and Their Inputs
+
+#### 1. `cmake-build.yaml`
+
+Builds and tests your project using CMake.
+
+**Usage Example:**
+
+```yaml
+jobs:
+  build_and_test:
+    uses: Framework-R-D/phlex/.github/workflows/cmake-build.yaml@main
+    with:
+      # Optional: A list of build combinations to run (e.g., "gcc/asan clang/tsan")
+      build-combinations: 'all -clang/valgrind'
+      # Required for PRs from forks if you want auto-formatting to work
+      ref: ${{ github.head_ref }}
+      repo: ${{ github.repository }}
+```
+
+**All Inputs:**
+*   `checkout-path` (string, optional): Path to check out code to.
+*   `build-path` (string, optional): Path for build artifacts.
+*   `skip-relevance-check` (boolean, optional, default: `false`): Bypass the check that only runs the build if C++ or CMake files have changed.
+*   `build-combinations` (string, optional): A space-separated list of build combinations to run.
+*   `ref` (string, optional): The branch or ref to check out.
+*   `repo` (string, optional): The repository to check out from (e.g., `my-org/my-repo`).
+*   `pr-base-sha` (string, optional): Base SHA of the PR for relevance check.
+*   `pr-head-sha` (string, optional): Head SHA of the PR for relevance check.
+
+#### 2. `python-check.yaml`
+
+Checks Python code for formatting and type errors using `ruff` and `mypy`.
+
+**Usage Example:**
+
+```yaml
+jobs:
+  check_python:
+    uses: Framework-R-D/phlex/.github/workflows/python-check.yaml@main
+```
+
+**All Inputs:**
+*   `checkout-path` (string, optional): Path to check out code to.
+*   `skip-relevance-check` (boolean, optional, default: `false`): Bypass the check that only runs if Python files have changed.
+*   `pr-base-sha` (string, optional): Base SHA of the PR for relevance check.
+*   `pr-head-sha` (string, optional): Head SHA of the PR for relevance check.
+
+#### 3. `cmake-format-fix.yaml`
+
+Automatically formats CMake files using `gersemi` and commits the changes. Typically triggered by an `issue_comment`.
+
+**Usage Example (in a workflow triggered by `issue_comment`):**
+
+```yaml
+name: 'Bot Commands'
+on:
+  issue_comment:
+    types: [created]
+
+jobs:
+  format-cmake:
+    # Run only on comments from collaborators/owners that start with the bot command
+    if: >
+      github.event.issue.pull_request &&
+      (github.event.comment.author_association == 'COLLABORATOR' || github.event.comment.author_association == 'OWNER') &&
+      startsWith(github.event.comment.body, format('@{0}bot format', github.event.repository.name))
+    uses: Framework-R-D/phlex/.github/workflows/cmake-format-fix.yaml@main
+    with:
+      # The ref and repo of the PR need to be retrieved and passed

+      repo: ${{ steps.get_pr_info.outputs.repo }}
+    secrets:
+      WORKFLOW_PAT: ${{ secrets.WORKFLOW_PAT }}
+```
+*Note: You would need a preliminary step (`get_pr_info`) to extract the PR's `ref` and `repo` from the `issue_comment` event.*
+
+**All Inputs:**
+*   `checkout-path` (string, optional): Path to check out code to.
+*   `ref` (string, **required**): The branch or ref to check out.
+*   `repo` (string, **required**): The repository to check out from.
+
+#### 4. `python-fix.yaml`
+
+Automatically formats and fixes Python code using `ruff` and commits the changes. Typically triggered by an `issue_comment`.
+
+**Usage Example (in a workflow triggered by `issue_comment`):**
+*Similar to `cmake-format-fix.yaml`, but triggered by a command like `@<repo>bot python-fix`.*
+
+**All Inputs:**
+*   `checkout-path` (string, optional): Path to check out code to.
+*   `ref` (string, **required**): The branch or ref to check out.
+*   `repo` (string, **required**): The repository to check out from.
+
+#### Other Workflows
+
+The repository also provides `actionlint-check.yaml`, `cmake-format-check.yaml`, and `codeql-analysis.yaml`, which can be used in a similar manner.

-# Composite Actions Refactoring Summary
-
-## Overview
-
-Refactored GitHub Actions workflows to use composite actions for better maintainability and single-point-of-maintenance of common functionality.
-
-## Created Composite Actions
-
-### 1. setup-build-env
-
-**Location**: `.github/actions/setup-build-env/action.yaml`
-
-**Purpose**: Verifies the Spack build environment and creates build directories
-
-**Provides**:
-
-- Creates build directory
-- Outputs source and build directory paths
-
-### 2. configure-cmake
-
-**Location**: `.github/actions/configure-cmake/action.yaml`
-
-**Purpose**: Configures CMake with preset detection and standard options
-
-**Features**:
-
-- Automatic CMakePresets.json detection
-- Configurable build type and extra options
-- Standard FORM options applied
-- Preset usage logging
-
-### 3. build-cmake
-
-**Location**: `.github/actions/build-cmake/action.yaml`
-
-**Purpose**: Builds the project with CMake
-
-**Features**:
-
-- Configurable target selection
-- Auto-detected or custom parallel jobs
-
-## Updated Workflows
-
-### cmake-build.yaml
-
-**Before**: ~45 lines of inline bash with duplicated logic
-**After**: Clean composite action calls
-
-**Changes**:
-
-- Replaced Configure CMake step with `configure-cmake` action
-- Replaced Build step with `build-cmake` action
-- Added `setup-build-env` action
-- Reduced from ~45 to ~20 lines for core build logic
-
-### clang-tidy-check.yaml
-
-**Before**: ~30 lines of duplicated CMake configuration
-**After**: Clean composite action calls
-
-**Changes**:
-
-- Replaced configuration/build steps with composite actions
-- Specified Debug build type and compile commands export
-- Consistent with cmake-build pattern
-
-### clang-tidy-fix.yaml
-
-**Before**: ~30 lines of duplicated CMake configuration
-**After**: Clean composite action calls
-
-**Changes**:
-
-- Same refactoring as clang-tidy-check
-- Maintains PR-specific checkout behavior
-
-## Benefits Achieved
-
-### 1. Single Point of Maintenance
-
-- **Container image**: Only needs updating in composite actions
-- **Preset detection logic**: Centralized in `configure-cmake`
-- **Standard CMake options**: Defined once in `configure-cmake`
-- **Environment setup**: Centralized in `setup-build-env`
-
-### 2. Consistency
-
-- All workflows use identical configuration patterns
-- Same preset detection across all builds
-- Uniform directory structure handling
-
-### 3. Reduced Duplication
-
-- Eliminated ~100+ lines of duplicated bash code
-- Preset detection logic written once, used everywhere
-- Build commands standardized
-
-### 4. Easier Updates
-
-- To change container image: Update one place
-- To add CMake option: Update `configure-cmake` inputs
-- To modify preset logic: Update one action file
-
-### 5. Better Readability
-
-- Workflows are more declarative
-- Intent is clearer (configure, then build)
-- Less inline bash to parse
-
-## Migration Path for Future Workflows
-
-New workflows should follow this pattern:
-
-```yaml
-steps:
-  - name: Checkout code
-    uses: actions/checkout@v4
-    with:
-      path: phlex-src
-
-  - name: Setup build environment
-    uses: ./phlex-src/.github/actions/setup-build-env
-
-  - name: Configure CMake
-    uses: ./phlex-src/.github/actions/configure-cmake
-    with:
-      build-type: <Release|Debug>
-      extra-options: '<additional options>'
-
-  - name: Build
-    uses: ./phlex-src/.github/actions/build-cmake
-    with:
-      target: <optional target>
-```
-
-## Maintenance Guidelines
-
-1. **Updating container image**: Edit container specification in each workflow (still needs updating in multiple places due to GitHub Actions limitation that composite actions cannot specify containers)
-
-2. **Updating CMake options**: Edit `configure-cmake/action.yaml` inputs and defaults
-
-3. **Updating preset logic**: Edit `configure-cmake/action.yaml` preset detection
-
-4. **Updating build logic**: Edit `build-cmake/action.yaml`
-
-5. **Testing changes**: Test composite action changes on feature branch before merging
-
-## Future Enhancements
-
-Potential future improvements:
-
-1. Add composite action for test execution
-2. Add composite action for artifact upload patterns
-3. Create preset for coverage builds
-4. Add validation checks to composite actions

Subject: [PATCH 7/7] docs: Recommend pinning reusable workflows to SHA

Updates the `REUSABLE_WORKFLOWS.md` documentation to address the security concerns raised in the review comments on PR #262.

The key changes are:
- The introductory note now explains the security risks of using a mutable branch like `@main` and recommends pinning to a specific commit SHA for stability and security.
- All `uses:` examples in the document have been updated to use a specific commit SHA instead of `@main`.
- The explanatory text clarifies that `@main` can still be used for development purposes at the user's own risk.

-**Note:** Always reference the workflows using the `@main` ref to ensure you are using the latest stable version.
+**Note:** For stability and security, it is highly recommended to pin the workflow to a specific commit SHA rather than a branch like `@main`. Using a mutable branch means you will automatically receive updates, which could include breaking changes or, in a worst-case scenario, malicious code. Pinning to a commit SHA ensures you are using a fixed, reviewed version of the workflow.
+
+For development purposes, you may choose to use `@main` at your own risk to get the latest changes.
