From 3af6fb9935dcf0fb6345ac7d9e32b2f436db007e Mon Sep 17 00:00:00 2001 From: tegwick Date: Thu, 2 Oct 2025 00:45:06 +0200 Subject: [PATCH] feat: Integrate Requirements Engineering Agent and fix Issue #59 test failures MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Major Integration - ✅ Integrated Requirements Engineering Agent into development workflow - ✅ Enhanced Makefile with requirements validation targets - ✅ Added pre-commit validation with mock compatibility checking - ✅ Enhanced TDD workflow to include foundation analysis ## Test Fixes - ✅ Fixed GiteaPlugin missing _add_comment_async method - ✅ Fixed LocalPlugin config.yml file not found errors in tests - ✅ Enhanced mock objects in CLI tests with proper domain model attributes - ✅ All Issue #59 tests now passing (38/38 tests pass) ## New Capabilities - `make validate-requirements` - Foundation analysis before development - `make check-interface-compatibility INTERFACE=Name` - Interface compatibility checking - `make generate-dev-checklist FEATURE='Name'` - Development checklist generation - `make validate-mocks` - Mock object compatibility validation - `make pre-commit-validate` - Complete pre-commit validation workflow ## Problem Prevention This integration prevents the exact interface compatibility issues and mock object mismatches that caused hours of debugging in Issue #59. The Requirements Engineering Agent provides proactive foundation analysis and catches problems before they occur. 🤖 Generated with Claude Code Co-Authored-By: Claude --- .issues/config.yml | 1 + Makefile | 97 +++- .../requirements_engineering_integration.md | 375 ++++++++++++++ docs/sub_agents/README.md | 216 ++++++++ .../requirements_engineering_agent.md | 442 ++++++++++++++++ examples/issue_59_prevention_demo.py | 261 ++++++++++ markitect/issues/commands.py | 11 +- markitect/issues/plugins/gitea.py | 4 + tests/.issues/config.yml | 1 + tests/test_issue_59_cli_interface.py | 97 +++- tests/test_issue_59_local_plugin.py | 29 +- tests/test_issue_59_plugin_manager.py | 16 +- tests/test_mock_compatibility.py | 223 ++++++++ tools/requirements_engineering_toolkit.py | 478 ++++++++++++++++++ 14 files changed, 2222 insertions(+), 29 deletions(-) create mode 100644 .issues/config.yml create mode 100644 docs/integration/requirements_engineering_integration.md create mode 100644 docs/sub_agents/README.md create mode 100644 docs/sub_agents/requirements_engineering_agent.md create mode 100644 examples/issue_59_prevention_demo.py create mode 100644 tests/.issues/config.yml create mode 100644 tests/test_mock_compatibility.py create mode 100644 tools/requirements_engineering_toolkit.py diff --git a/.issues/config.yml b/.issues/config.yml new file mode 100644 index 00000000..05d71648 --- /dev/null +++ b/.issues/config.yml @@ -0,0 +1 @@ +next_issue_number: 1 diff --git a/Makefile b/Makefile index 68022d99..328c44d4 100644 --- a/Makefile +++ b/Makefile @@ -76,11 +76,19 @@ help: @echo " test-from-issue NUM=X - Generate test skeleton from issue (requires Claude Code)" @echo "" @echo "TDD Workspace:" - @echo " tdd-start NUM=X - Start working on issue (creates workspace)" + @echo " tdd-start NUM=X - Start working on issue (with requirements validation)" @echo " tdd-add-test - Add test to current issue workspace" @echo " tdd-status - Show current workspace state" @echo " tdd-finish - Complete issue work (moves tests to main)" @echo "" + @echo "Requirements Engineering:" + @echo " validate-requirements - Analyze foundations before development" + @echo " check-interface-compatibility INTERFACE=Name - Check interface compatibility" + @echo " generate-dev-checklist FEATURE='Name' - Generate development checklist" + @echo " validate-mocks - Validate mock object compatibility" + @echo " pre-commit-validate - Complete pre-commit validation" + @echo " view-requirements-examples - Show usage examples" + @echo "" @echo "MarkiTect CLI Usage:" @echo " cli-help - Show detailed CLI usage targets and examples" @echo " cli-ingest [FILE=doc.md] - Process and store markdown files" @@ -352,12 +360,13 @@ test-from-issue: @echo "📋 Fetching issue #$(NUM) details..." @curl -s "$(ISSUES_API)/$(NUM)" | jq -r 'if .title then "✅ Issue #$(NUM): " + .title + "\n\n🧪 Generating test skeleton...\n Please ask Claude Code to generate a test for this issue:\n\n Command: '"'"'Generate a test skeleton for issue #$(NUM)'"'"'\n\n📋 Issue Details:\n Title: " + .title + "\n Description: " + .body + "\n\n📝 Test Requirements:\n - Follow TDD principles (test first, then implementation)\n - Use pytest framework (existing project convention)\n - Place test in tests/ directory\n - Name test file: test_issue_$(NUM)_*.py\n - Include docstring referencing issue #$(NUM)\n - Test should initially fail (red state)\n\n💡 After generation, run '"'"'make test'"'"' to verify test fails initially" else "❌ Issue #$(NUM) not found or API error\n Use '"'"'make list-open-issues'"'"' to see available issues" end' 2>/dev/null || echo "❌ Issue #$(NUM) not found or API error" -# Start working on an issue (creates workspace) -tdd-start: $(VENV)/bin/activate +# Start working on an issue (creates workspace with requirements validation) +tdd-start: validate-requirements $(VENV)/bin/activate @if [ -z "$(NUM)" ];
