+# skills Development Patterns
+
+> Auto-generated skill from repository analysis
+
+## Overview
+
+This repository demonstrates best practices for developing modular Python "skills" without a framework. It emphasizes clear documentation, consistent coding conventions, and structured workflows for adding, enhancing, and documenting skill packages. The patterns here are ideal for maintainable, collaborative Python codebases.
+
+## Coding Conventions
+
+- **File Naming:**  
+  Use PascalCase for Python files and directories.  
+  *Example:*  
+  ```
+  CodexCrossProviderSessionRepair/
+  RepairSession.py
+  ```
+
+- **Import Style:**  
+  Use relative imports within skill packages.  
+  *Example:*  
+  ```python
+  from .RepairSession import RepairSession
+  ```
+
+- **Export Style:**  
+  Use named exports (explicitly define what is exported).  
+  *Example:*  
+  ```python
+  __all__ = ["RepairSession"]
+  ```
+
+- **Commit Messages:**  
+  Follow the [Conventional Commits](https://www.conventionalcommits.org/) style.  
+  - Prefixes: `docs`, `feat`
+  - Example:  
+    ```
+    docs: update SKILL.md with new workflow
+    feat: add session repair logic
+    ```
+
+## Workflows
+
+### update-documentation-files
+**Trigger:** When you want to improve, clarify, or add documentation for the repository or a skill.  
+**Command:** `/update-docs`
+
+1. Edit or add content to `README.md` at the root or within a skill directory.
+2. Optionally update or add language-specific README files (e.g., `README.zh-CN.md`).
+3. Update `CHANGELOG.md` and/or `SKILL.md` as needed.
+4. Commit changes with a `docs:`-prefixed message.
+
+*Example:*
+```bash
+# Edit documentation files
+git add codex-cross-provider-session-repair/README.md
+git commit -m "docs: clarify session repair steps"
+```
+
+---
+
+### add-or-enhance-skill-package
+**Trigger:** When you want to introduce a new skill or make significant updates to an existing skill's implementation and documentation.  
+**Command:** `/add-skill`
+
+1. Create or update the skill directory with necessary files (`README.md`, `SKILL.md`, scripts, tests, etc.).
+2. Add or update scripts (e.g., `install.sh`, `package.py`, `repair.py`).
+3. Update or add tests in the `tests/` subdirectory.
+4. Update documentation files within the skill (`README.md`, `CHANGELOG.md`, `SKILL.md`, etc.).
+5. Commit all changes together.
+
+*Example:*
+```bash
+# Add a new skill
+mkdir codex-cross-provider-session-repair
+touch codex-cross-provider-session-repair/README.md
+touch codex-cross-provider-session-repair/SKILL.md
+touch codex-cross-provider-session-repair/scripts/repair.py
+mkdir codex-cross-provider-session-repair/tests
+touch codex-cross-provider-session-repair/tests/test_repair.py
+
+git add codex-cross-provider-session-repair/
+git commit -m "feat: add codex cross-provider session repair skill"
+```
+
+## Testing Patterns
+
+- **Framework:** Not explicitly specified; use standard Python testing practices.
+- **Test File Pattern:** Name test files as `*.test.*` or place them in a `tests/` subdirectory.
+- **Example:**
+  ```
+  codex-cross-provider-session-repair/tests/test_repair.py
+  ```
+- **Typical Test Structure:**
+  ```python
+  import unittest
+  from ..scripts.repair import repair_session
+
+  class TestRepairSession(unittest.TestCase):
+      def test_repair(self):
+          self.assertTrue(repair_session())
+  ```
+
+## Commands
+
+| Command      | Purpose                                                       |
+|--------------|---------------------------------------------------------------|
+| /update-docs | Update documentation files (README, SKILL.md, CHANGELOG, etc) |
+| /add-skill   | Add or enhance a skill package with code, tests, and docs     |
+```

+
+Use this workflow when working on **add-or-enhance-skill-package** in `skills`.
+
+## Goal
+
+Adds a new skill package or enhances an existing one by updating code, scripts, tests, and documentation within the skill directory.
+
+## Common Files
+
+- `codex-cross-provider-session-repair/README.md`
+- `codex-cross-provider-session-repair/SKILL.md`
+- `codex-cross-provider-session-repair/CHANGELOG.md`
+- `codex-cross-provider-session-repair/scripts/install.sh`
+- `codex-cross-provider-session-repair/scripts/package.py`
+- `codex-cross-provider-session-repair/scripts/repair.py`
+
+## Suggested Sequence
+
+1. Understand the current state and failure mode before editing.
+2. Make the smallest coherent change that satisfies the workflow goal.
+3. Run the most relevant verification for touched files.
+4. Summarize what changed and what still needs review.
+
+## Typical Commit Signals
+
+- Create or update the skill directory with necessary files (README, SKILL.md, scripts, tests, etc.)
+- Add or update scripts (e.g., install.sh, package.py, repair.py)
+- Update or add tests in the tests/ subdirectory
+- Update documentation files within the skill (README.md, CHANGELOG.md, SKILL.md, etc.)
+- Commit all changes together
+
+## Notes
+
+- Treat this as a scaffold, not a hard-coded script.
+- Update the command if the workflow evolves materially.
