+# GitHub Actions CI/CD
+
+This directory contains GitHub Actions workflows for the sqlite-mcp-server project.
+
+## Workflows
+
+### `ci.yml` - Continuous Integration
+
+This workflow runs on:
+- Every push to `main` and `develop` branches
+- Every pull request targeting `main` and `develop` branches
+- Pull request events (opened, synchronize, reopened)
+
+#### Jobs
+
+1. **Test** - Runs tests across multiple Go versions
+   - Go versions: 1.21, 1.22, 1.23
+   - Runs unit tests with race detection
+   - Generates coverage reports
+   - Uploads coverage to Codecov (only for Go 1.23)
+
+2. **Lint** - Code quality checks
+   - Runs golangci-lint with comprehensive linting rules
+   - Checks code formatting, style, and potential issues
+   - Uses custom configuration from `.golangci.yml`
+
+3. **Integration Test** - End-to-end testing
+   - Builds the server binary
+   - Sets up test databases
+   - Runs quick integration tests
+   - Depends on test and lint jobs passing
+
+4. **Security** - Security scanning
+   - Runs Gosec security scanner
+   - Uploads results to GitHub Security tab
+   - Scans for common security vulnerabilities
+
+5. **Status Check** - PR status summary
+   - Summarizes all job results for PR requirements
+   - Posts status comments on pull requests
+   - Updates existing status comments instead of creating duplicates
+   - Required for PR merges
+
+### `release.yml` - Automatic Tagging and Releases
+
+This workflow automatically creates tags and releases when code is merged to the `main` branch.
+
+#### Triggers
+- **Automatic**: Every push to `main` branch (after successful PR merge)
+- **Manual**: Workflow dispatch with version type selection
+
+#### Jobs
+
+1. **Check Changes** - Analyzes commits for release-worthy changes
+   - Examines commit messages since last tag
+   - Determines appropriate version bump (major/minor/patch)
+   - Skips release if no significant changes
+
+2. **Create Tag** - Generates new version tag and GitHub release
+   - Calculates semantic version based on commit analysis
+   - Supports manual version override via workflow dispatch
+   - Runs final tests before tagging
+   - Generates automated changelog
+   - Creates annotated Git tag
+
+3. **Build Release Assets** - Cross-platform binary compilation
+   - Linux AMD64/ARM64
+   - macOS AMD64/ARM64 (Intel/Apple Silicon)
+   - Windows AMD64
+   - Generates SHA256 checksums
+
+4. **Create GitHub Release** - Publishes release with assets
+   - Uploads all platform binaries
+   - Includes automated changelog
+   - Links to full commit comparison
+
+5. **Notify** - Reports release status
+   - Success/failure notifications
+   - Links to new release
+
+#### Version Bump Logic
+- **Major** (`1.x.x`): Commits with `BREAKING`, `major`, `feat!`, `fix!`
+- **Minor** (`x.1.x`): Commits with `feat`, `feature`
+- **Patch** (`x.x.1`): All other changes (fixes, docs, etc.)
+
+## Manual Release
+
+You can manually trigger a release from the GitHub Actions tab:
+
+1. Go to **Actions** → **Release and Tagging**
+2. Click **Run workflow**
+3. Choose:
+   - **Version bump type**: `patch`, `minor`, or `major`
+   - **Custom version**: Override with specific version (e.g., `v2.1.0`)
+4. Click **Run workflow**
+
+This is useful for:
+- Creating releases outside of the normal merge cycle
+- Fixing version numbering issues
+- Creating custom version numbers
+
+## Local Development
+
+You can run the same checks locally using the Makefile:
+
+```bash
+# Install golangci-lint and run all CI checks
+make ci-local
+
+# Run just the linter
+make lint
+
+# Run linter with auto-fix
+make lint-fix
+
+# Run tests with race detection
+make test-race
+
+# Generate coverage report
+make coverage
+```
+
+## Configuration Files
+
+- `.golangci.yml` - golangci-lint configuration
+  - Enables comprehensive set of linters
+  - Customized rules for the project
+  - Excludes certain checks for test files
+
+## Pull Request Features
+
+The CI workflow includes several PR-specific enhancements:
+
+### Automated Comments
+- **Test Results**: Comments with build and test status
+- **Status Summary**: Comprehensive status check with all job results
+- **Smart Updates**: Updates existing comments instead of creating duplicates
+
+### Status Checks
+- All jobs must pass for PR merge approval
+- Clear visual indicators for each job status
+- Links to detailed action logs
+
+### Security Integration
+- SARIF upload to GitHub Security tab
+- Security findings visible in PR conversations
+- Automated security scanning on every PR
+
+## Coverage Reports
+
+- Coverage reports are generated for each test run
+- Codecov integration provides detailed coverage tracking
+- HTML coverage reports are generated locally with `make coverage-html`
+- Coverage changes are tracked and reported on PRs
