Step-by-Step Instructions

1. Agent Specialization Overview

SPECIALIZATION PRINCIPLE
══════════════════════════════════════════════════════════════

Generalist Agent:
  ✓ Can do many things
  ✗ Master of none
  ✗ Inconsistent quality across domains
  ✗ Hard to maintain quality as scope grows

Specialist Agents:
  ✓ Deep expertise in one domain
  ✓ Consistent high-quality output
  ✓ Targeted skill sets reduce errors
  ✓ Can be independently improved
  ✗ Need coordination (→ multi-agent-coordinator)

RULE: A specialist should NEVER attempt work outside its
domain. Instead, it should request a handoff.

8. Handoff Protocol

HANDOFF PROTOCOL
══════════════════════════════════════════════════════════════

When an agent needs to hand off work to another:

1. RECOGNIZE THE BOUNDARY
   "This task requires database changes — outside my domain"

2. PREPARE HANDOFF PACKAGE
   {
     "from": "frontend-agent",
     "to": "backend-agent",
     "type": "handoff",
     "context": {
       "why": "New feature requires a new API endpoint",
       "current_state": "UI component ready, waiting for API",
       "requirements": [
         "GET /api/notifications?unread=true",
         "Response: { items: Notification[], total: number }",
         "Must support pagination (page, limit params)"
       ],
       "files_in_progress": ["src/components/NotificationBell.tsx"],
       "blocked_until": "API endpoint is available"
     }
   }

3. COORDINATOR ROUTES THE HANDOFF
   - Validates the receiving agent has capacity
   - Adds context from the handoff package
   - Assigns the new task with source reference

4. RECEIVING AGENT ACKNOWLEDGES
   - Confirms understanding of requirements
   - Asks clarification if needed (through coordinator)
   - Begins work

5. COMPLETION CALLBACK
   - Receiving agent notifies coordinator when done
   - Coordinator unblocks the originating agent
   - Originating agent resumes with the new deliverable

9. Knowledge Boundary Definition

DEFINING KNOWLEDGE BOUNDARIES
══════════════════════════════════════════════════════════════

For each specialist, define three zones:

GREEN ZONE (Full Authority):
  - Agent can act independently
  - No review needed
  - Example: Frontend agent modifying React components

YELLOW ZONE (Collaboration Required):
  - Agent can propose changes
  - Needs review from another specialist
  - Example: Backend agent adding auth middleware (security review)

RED ZONE (Forbidden):
  - Agent must NOT act
  - Must request handoff
  - Example: Frontend agent modifying database schemas

BOUNDARY ENFORCEMENT:
  Option 1: File-path based (agent can only modify certain directories)
  Option 2: Skill-based (agent only attempts tasks matching its skills)
  Option 3: Review-based (all changes reviewed by the domain owner)
  Recommended: Combine all three for defense in depth

10. Adding a New Specialist

# Template for creating a new specialist agent

agent: <domain>-specialist
name: "<Domain> Agent"
description: >
  <One paragraph describing the agent's expertise and purpose>

skills:
  - <Skill 1>
  - <Skill 2>
  - <Skill 3>
  # List 8-15 specific skills

system_prompt: |
  You are a <Domain> Specialist Agent.
  
  ALWAYS:
  - <Rule 1>
  - <Rule 2>
  
  NEVER:
  - <Restriction 1>
  - <Restriction 2>
  
  HANDOFF TRIGGERS:
  - "<Condition>" → handoff to <agent>

boundaries:
  can_modify:
    - "<glob pattern>"
  can_review:
    - "<glob pattern>"
  cannot_modify:
    - "<glob pattern>"

Best Practices

Keep specialists focused — a narrow domain produces better output
Define clear boundaries — ambiguity leads to conflicts and duplication
Use handoff protocols — never let an agent silently work outside its domain
Give security veto power — security decisions should not be overridden by convenience
Version specialist configs — track changes to agent configurations in version control
Test specialist boundaries — verify agents refuse out-of-scope tasks
Start with 3 agents — frontend, backend, devops; add more as needed
Share contracts — agents should agree on interfaces (API specs, schemas)
Review handoffs — monitor handoff frequency to optimize task decomposition
Iterate on prompts — refine system prompts based on observed agent behavior
