Use PROACTIVELY when user says "design", "architecture", "structure", "pattern", "framework", "system design", "component", "module", "interface", or "abstraction". Automatically delegate for architectural decisions, system design, pattern selection, component decomposition, and strategic technical planning. Senior software architect specializing in scalable, maintainable solutions.

Use PROACTIVELY and IMMEDIATELY when encountering errors, test failures, stack traces, crashes, or unexpected behavior. Automatically delegate when user says "debug", "error", "fix", "failing", "broken", "issue", "bug", "crash", or "exception". Expert debugging specialist for root cause analysis and rapid issue resolution.

Use PROACTIVELY when user says "implement", "build", "create", "develop", "feature", "add", "write code", or "execute spec". Automatically delegate for specification-driven development, feature implementation, code writing, and acceptance criteria execution. Specification-driven feature development specialist who transforms specs into production-ready code.

Use PROACTIVELY when user requests "plan", "create spec", "break down", "decompose", "estimate", "strategy", or "requirements analysis". Automatically delegate for transforming ambiguous requirements into clear specifications, strategic decomposition, dependency mapping, and comprehensive planning. Strategic planning specialist who creates implementation-ready specifications.

Use PROACTIVELY after implementation when user says "test", "testing", "qa", "quality", "coverage", "validation", "verify", or "assert". Automatically delegate for creating comprehensive test suites, identifying edge cases, validating implementations, and ensuring high code quality standards. Testing and quality assurance specialist.

Use PROACTIVELY when user says "refactor", "improve", "cleanup", "optimize", "restructure", "simplify", "reduce complexity", "extract", or "consolidate". Automatically delegate for code quality improvements, technical debt reduction, and maintainability enhancements while preserving behavior. Code improvement and refactoring specialist.

Use PROACTIVELY when user says "research", "explore", "find", "search", "analyze", "understand", "investigate", "discover", "map", "trace", or "locate". Automatically delegate for multi-file analysis, codebase exploration, pattern discovery, dependency mapping, and architecture understanding tasks. Deep codebase exploration specialist with advanced search strategies.

Use PROACTIVELY after implementation or when user says "review", "quality check", "audit", "inspect", "validate", "assess", "evaluate", or "critique". Automatically delegate before shipping code for comprehensive quality review, security analysis, best practices validation, and actionable feedback. Senior code reviewer ensuring highest standards.

Use PROACTIVELY when user mentions "security", "vulnerability", "auth", "authentication", "authorization", "encryption", "crypto", "token", "password", "injection", "xss", "csrf", or "owasp". Automatically delegate for security-sensitive code, authentication systems, encryption implementations, and vulnerability detection. Senior security engineer ensuring secure coding practices.

Use PROACTIVELY and IMMEDIATELY before ANY implementation request to verify Research→Plan→Implement workflow compliance. Automatically delegate to enforce proper phase progression, check for active specifications, and prevent premature implementation. Reports violations without forcing fixes - primary agent decides next steps.

Systematically debug issues with reproduction steps, error analysis, hypothesis testing, and root cause fixes. Use when investigating bugs, analyzing production incidents, or troubleshooting unexpected behavior.

Execute specification-driven implementation with automatic quality gates, multi-agent orchestration, and progress tracking. Use when building features from specs, fixing bugs with test coverage, or refactoring with validation.

Intelligent project analysis with auto-framework detection and adaptive setup. Use when user wants to initialize Quaestor, setup a new project, or analyze existing project structure.

Create, manage, and track specifications through their full lifecycle from draft to completion. Use when user wants to plan features, create specs, check progress, activate work, or complete specifications.

Optimize performance with profiling, caching strategies, database query optimization, and bottleneck analysis. Use when improving response times, implementing caching layers, or scaling for high load.

Validate quality with multi-agent review, auto-fix issues, generate organized commits, and create PRs with rich context. Use after completing features to ensure quality gates pass and ship confidently.

Audit security with vulnerability scanning, input validation checks, and auth/authz review against OWASP Top 10. Use when implementing authentication, reviewing security-sensitive code, or conducting security audits.
