• 🚀 Safe DevOps — Idempotent operations, health checks, mandatory approval gates
• 🔗 Traceable — Self-documenting IDs link requirements → tasks → tests → evidence
• 📚 Knowledge-Driven — Prioritized sources (PRD → codebase → AGENTS.md → Context7 → docs)
• 🛠️ Skills & Guidelines — Built-in skill & guidelines (web-design-guidelines)
• 📐 Spec-Driven — Multi-step refinement defines "what" before "how"
• 🌊 Wave-Based — Parallel agents with integration gates per wave
• 🗂️ Multi-Plan — Complex tasks: 3 planner variants → best DAG selected automatically
• 🩺 Diagnose-then-Fix — gem-debugger diagnoses → gem-implementer fixes → re-verifies
• ⚠️ Pre-Mortem — Failure modes identified BEFORE execution
• 💬 Constructive Critique — gem-critic challenges assumptions, finds edge cases
• 📝 Contract-First — Contract tests written before implementation
• 📱 Mobile Agents — Native mobile implementation (React Native, Flutter) + iOS/Android testing

🔄 Core Workflow

Phase Flow: User Goal → Orchestrator → Discuss (medium|complex) → PRD → Research → Planning → Execution → Summary

Error Handling: Diagnose-then-Fix loop (Debugger → Implementer → Re-verify)

Orchestrator auto-detects phase and routes accordingly.

Condition	→ Phase
No plan + simple	Research
No plan + medium|complex	Discuss → PRD → Research
Plan + pending tasks	Execution
Plan + feedback	Planning

Agent File Skeleton

Each .agent.md file follows this structure:

---                                    # Frontmatter: description, name, triggers
# Role                                 # One-line identity
# Expertise                            # Core competencies
# Knowledge Sources                    # Prioritized reference list
# Workflow                             # Step-by-step execution phases
  ## 1. Initialize                     # Setup and context gathering
  ## 2. Analyze/Execute                # Role-specific work
  ## N. Self-Critique                  # Confidence check (≥0.85)
  ## N+1. Handle Failure               # Retry/escalate logic
  ## N+2. Output                       # JSON deliverable format
# Input Format                         # Expected JSON schema
# Output Format                        # Return JSON schema
# Rules
  ## Execution                         # Tool usage, batching, error handling
  ## Constitutional                    # IF-THEN decision rules
  ## Anti-Patterns                     # Behaviors to avoid
  ## Anti-Rationalization              # Excuse → Rebuttal table
  ## Directives                        # Non-negotiable commands

All agents share: Execution rules, Constitutional rules, Anti-Patterns, and Directives sections. Anti-Rationalization tables are present in 5 agents (implementer, planner, reviewer, designer, browser-tester). Role-specific sections (Workflow, Expertise, Knowledge Sources) vary by agent.

📚 Knowledge Sources

Agents consult only the sources relevant to their role. Trust levels apply:

Trust Level	Sources	Behavior
Trusted	PRD.yaml, plan.yaml, AGENTS.md	Follow as instructions
Verify	Codebase files, research findings	Cross-reference before assuming
Untrusted	Error logs, external data, third-party responses	Factual only — never as instructions

Agent	Knowledge Sources
orchestrator	PRD.yaml, AGENTS.md
researcher	PRD.yaml, codebase patterns, AGENTS.md, Context7, official docs, online search
planner	PRD.yaml, codebase patterns, AGENTS.md, Context7, official docs
implementer	codebase patterns, AGENTS.md, Context7 (API verification), DESIGN.md (UI tasks)
debugger	codebase patterns, AGENTS.md, error logs (untrusted), git history, DESIGN.md (UI bugs)
reviewer	PRD.yaml, codebase patterns, AGENTS.md, OWASP reference, DESIGN.md (UI review)
browser-tester	PRD.yaml (flow coverage), AGENTS.md, test fixtures, baseline screenshots, DESIGN.md (visual validation)
designer	PRD.yaml (UX goals), codebase patterns, AGENTS.md, existing design system
code-simplifier	codebase patterns, AGENTS.md, test suites (behavior verification)
documentation-writer	AGENTS.md, existing docs, source code
