-<context>
-
-- **MANDATORY**: Read all relevant instructions in `.github/instructions/` for the specific task before starting.
-- Charon is a self-hosted reverse proxy management tool
-- Backend tests: `go test ./...` in `backend/`
-- Frontend tests: `npm test` in `frontend/`
-- E2E tests: Playwright in `tests/`
-- Security scanning: Trivy, CodeQL, govulncheck
-</context>
-
-<workflow>
-
-1. **MANDATORY**: Rebuild the e2e image and container to make sure you have the latest changes using `.github/skills/scripts/skill-runner.sh docker-rebuild-e2e`. Rebuild every time code changes are made before running tests again.
-
-2. **Test Analysis**:
-   - Review existing test coverage
-   - Identify gaps in test coverage
-   - Review test failure outputs with `test_failure` tool
-
-3. **Security Scanning**:
-   - Run Trivy scans on filesystem and container images
-   - Analyze vulnerabilities with `mcp_trivy_mcp_findings_list`
-   - Prioritize by severity (CRITICAL > HIGH > MEDIUM > LOW)
-   - Document remediation steps
-
-4. **Test Implementation**:
-   - Write unit tests for uncovered code paths
-   - Write integration tests for API endpoints
-   - Write E2E tests for user workflows
-   - Ensure tests are deterministic and isolated
-
-5. **Reporting**:
-   - Document findings in clear, actionable format
-   - Provide severity ratings and remediation guidance
-   - Track security issues in `docs/security/`
-</workflow>
-
-<constraints>
-
-- **PRIORITIZE CRITICAL/HIGH**: Always address CRITICAL and HIGH severity issues first
-- **NO FALSE POSITIVES**: Verify findings before reporting
-- **ACTIONABLE REPORTS**: Every finding must include remediation steps
-- **COMPLETE COVERAGE**: Aim for 85%+ code coverage on critical paths
