+# Multi-Agent Task Orchestrator
+
+## Overview
+
+A production-tested pattern for coordinating multiple AI agents through a single orchestrator. Instead of letting agents work independently (and conflict), one orchestrator decomposes tasks, routes them to specialists, prevents duplicate work, and verifies results before marking anything done. Battle-tested across 10,000+ tasks over 6 months.
+
+## When to Use This Skill
+
+- Use when you have 3+ specialized agents that need to coordinate on complex tasks
+- Use when agents are doing duplicate or conflicting work
+- Use when you need audit trails showing who did what and when
+- Use when agent output quality is inconsistent and needs verification gates
+
+## How It Works
+
+### Step 1: Define the Orchestrator Identity
+
+The orchestrator must know what it IS and what it IS NOT. This prevents it from doing work instead of delegating:
+
+```
+You are the Task Orchestrator. You NEVER do specialized work yourself.
+You decompose tasks, delegate to the right agent, prevent conflicts,
+and verify quality before marking anything done.
+
+WHAT YOU ARE NOT:
+- NOT a code writer — delegate to code agents
+- NOT a researcher — delegate to research agents
+- NOT a tester — delegate to test agents
+```
+
+This "NOT-block" pattern reduces task drift by ~35% in production.
+
+### Step 2: Build a Task Registry
+
+Before assigning work, check if anyone is already doing this task:
+
+```python
+import sqlite3
+from difflib import SequenceMatcher
+
+def check_duplicate(description, threshold=0.55):
+    conn = sqlite3.connect("task_registry.db")
+    c = conn.cursor()
+    c.execute("SELECT id, description, agent, status FROM tasks WHERE status IN ('pending', 'in_progress')")
+    for row in c.fetchall():
+        ratio = SequenceMatcher(None, description.lower(), row[1].lower()).ratio()
+        if ratio >= threshold:
+            return {"id": row[0], "description": row[1], "agent": row[2]}
+    return None
+```
+
+### Step 3: Route Tasks to Specialists
+
+Use keyword scoring to match tasks to the best agent:
+
+```python
+AGENTS = {
+    "code-architect": ["code", "implement", "function", "bug", "fix", "refactor", "api"],
+    "security-reviewer": ["security", "vulnerability", "audit", "cve", "injection"],
+    "researcher": ["research", "compare", "analyze", "benchmark", "evaluate"],
+    "doc-writer": ["document", "readme", "explain", "tutorial", "guide"],
+    "test-engineer": ["test", "coverage", "unittest", "pytest", "spec"],
+}
+
+def route_task(description):
+    scores = {}
+    for agent, keywords in AGENTS.items():
+        scores[agent] = sum(1 for kw in keywords if kw in description.lower())
+    return max(scores, key=scores.get) if max(scores.values()) > 0 else "code-architect"
+```
+
+### Step 4: Enforce Quality Gates
+
+Agent output is a CLAIM. Test output is EVIDENCE.
+
+```
+After agent reports completion:
+1. Were files actually modified? (git diff --stat)
+2. Do tests pass? (npm test / pytest)
+3. Were secrets introduced? (grep for API keys, tokens)
+4. Did the build succeed? (npm run build)
+5. Were only intended files touched? (scope check)
+
+Mark done ONLY after ALL checks pass.
+```
+
+### Step 5: Run 30-Minute Heartbeats
+
+```
+Every 30 minutes, ask:
+1. "What have I DELEGATED in the last 30 minutes?"
+2. If nothing → open the task backlog and assign the next task
+3. Check for idle agents (no message in >30min on assigned task)
+4. Relance idle agents or reassign their tasks
+```
+
+## Examples
+
+### Example 1: Delegating a Code Task
+
+```
+[ORCHESTRATOR -> code-architect] TASK: Add rate limiting to /api/users
+SCOPE: src/middleware/rate-limit.ts only
+VERIFICATION: npm test -- --grep "rate-limit"
+DEADLINE: 30 minutes
+```
+
+### Example 2: Handling a Duplicate
+
+```
+User asks: "Fix the login bug"
+Registry check: Task #47 "Fix authentication bug" is IN_PROGRESS by security-reviewer
+Decision: SKIP — similar task already assigned (78% match)
+Action: Notify user of existing task, wait for completion
+```
+
+## Best Practices
+
+- Always define NOT-blocks for every agent (what they must refuse to do)
+- Use SQLite for the task registry (lightweight, no server needed)
+- Set similarity threshold at 55% for anti-duplication (lower = too many false positives)
+- Require evidence-based quality gates (not just agent claims)
+- Log every delegation with: task ID, agent, scope, deadline, verification command
+
+## Common Pitfalls
+
+- **Problem:** Orchestrator starts doing work instead of delegating
+  **Solution:** Add explicit NOT-blocks and role boundaries
+
+- **Problem:** Two agents modify the same file simultaneously
+  **Solution:** Task registry with file-level locking and queue system
+
+- **Problem:** Agent claims "done" without actual changes
+  **Solution:** Quality gate checks git diff before accepting completion
+
+- **Problem:** Tasks pile up without progress
+  **Solution:** 30-minute heartbeat catches stale assignments and reassigns
