Capability Evolver

Meta-skill for AI agent self-improvement. Analyzes runtime logs to detect error patterns, regressions, and inefficiencies, then generates structured improvement proposals. Use when the user or agent asks to analyze logs, diagnose failures, improve agent reliability, generate evolution proposals, or assess system health. Supports analyze, evolve, and status actions.

What is This?

This is a native skill for OpenClaw and other AI agents. Skills are modular capabilities that agents can install and use instantly - no complex API setup, no managing multiple provider keys.

Real-World Use Cases

Scenario 1: Production Incident Response

Problem: Your agent crashed in production and you need to understand why

Solution:

1. Export last 1000 log entries
2. Run analyze action
3. Get error patterns and cascades
4. Identify root cause in minutes

Example:

const logs = await db.logs.findMany({ 
  where: { timestamp: { gte: incidentStart } },
  orderBy: { timestamp: 'asc' }
});

const analysis = await claw0x.call('capability-evolver', {
  action: 'analyze',
  logs: logs.map(l => ({
    timestamp: l.timestamp,
    level: l.level,
    message: l.message,
    context: l.context
  }))
});

// analysis.patterns shows: "auth-service.ts failed, then payment-api.ts failed"
// Root cause: auth service timeout cascaded to payment failures

Scenario 2: Continuous Improvement Pipeline

Problem: You want your agent to automatically improve based on production data

Solution:

1. Schedule daily log analysis
2. Generate evolution proposals
3. Auto-create GitHub issues for high-priority items
4. Track improvement over time

Example:

// Cron job: every day at 2am
async function dailyEvolution() {
  const logs = await getLast24HoursLogs();
  
  const evolution = await claw0x.call('capability-evolver', {
    action: 'evolve',
    logs,
    strategy: 'balanced'
  });
  
  // Create issues for critical recommendations
  for (const rec of evolution.recommendations.filter(r => r.priority === 'critical')) {
    await github.issues.create({
      title: `[Auto] ${rec.category}: ${rec.description}`,
      body: `Risk: ${rec.risk}\nApproach: ${rec.approach}`,
      labels: ['auto-generated', 'reliability']
    });
  }
  
  // Track health score trend
  await metrics.record('agent_health_score', evolution.estimated_improvement);
}
// Result: Health score improved from 45 to 85 over 3 months

Scenario 3: Multi-Agent Fleet Management

Problem: Managing 50+ agent instances, need to identify systemic issues

Solution:

1. Aggregate logs from all agents
2. Batch analyze to find common patterns
3. Fix once, deploy to all agents
4. Reduce fleet-wide error rate

Example:

# Collect logs from all agents
all_logs = []
for agent_id in agent_fleet:
    logs = fetch_agent_logs(agent_id, last_24h)
    all_logs.extend(logs)

# Analyze fleet-wide
result = client.call("capability-evolver", {
    "action": "analyze",
    "logs": all_logs
})

# result.patterns shows: "40 of 50 agents failing on auth-service.ts"
# Fix auth-service.ts once, deploy to all agents
# Result: 80% reduction in fleet-wide errors

Scenario 4: Pre-Deployment Health Check

Problem: Want to ensure new deployment doesn't introduce regressions

Solution:

1. Analyze logs from staging environment
2. Compare health score to production baseline
3. Block deployment if health score drops
4. Catch regressions before production

Example:

# .github/workflows/deploy.yml
- name: Health Check
  run: |
    STAGING_LOGS=$(fetch-logs staging)
    
    RESULT=$(curl -X POST https://api.claw0x.com/v1/call \
      -H "Authorization: Bearer $CLAW0X_API_KEY" \
      -d "{\"skill\":\"capability-evolver\",\"input\":{\"action\":\"analyze\",\"logs\":$STAGING_LOGS}}")
    
    HEALTH_SCORE=$(echo $RESULT | jq -r '.health_score')
    BASELINE=75
    
    if [ $HEALTH_SCORE -lt $BASELINE ]; then
      echo "Health score $HEALTH_SCORE below baseline $BASELINE"
      exit 1
    fi
# Result: Zero regression-related incidents in 6 months

Integration Recipes

OpenClaw Agent

import { Claw0xClient } from '@claw0x/sdk';

const claw0x = new Claw0xClient(process.env.CLAW0X_API_KEY);

// Analyze logs after each run
agent.onComplete(async () => {
  const logs = agent.getRecentLogs();
  
  const analysis = await claw0x.call('capability-evolver', {
    action: 'analyze',
    logs
  });
  
  if (analysis.health_score < 70) {
    console.warn('⚠️ Health score low:', analysis.health_score);
    console.log('Recommendations:', analysis.recommendations);
  }
});

LangChain Agent

from claw0x import Claw0xClient
import os

client = Claw0xClient(api_key=os.getenv("CLAW0X_API_KEY"))

def analyze_agent_health(logs):
    result = client.call("capability-evolver", {
        "action": "analyze",
        "logs": logs
    })
    
    return {
        "health_score": result["health_score"],
        "patterns": result["patterns"],
        "recommendations": result["recommendations"]
    }

# Use in monitoring
health = analyze_agent_health(agent.logs)
if health["health_score"] < 70:
    alert_team(health)

Custom Monitoring Dashboard

// Real-time health monitoring
async function updateHealthDashboard() {
  const logs = await db.logs.findMany({
    where: { timestamp: { gte: Date.now() - 3600000 } } // last hour
  });
  
  const analysis = await fetch('https://api.claw0x.com/v1/call', {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${process.env.CLAW0X_API_KEY}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      skill: 'capability-evolver',
      input: { action: 'analyze', logs }
    })
  });
  
  const result = await analysis.json();
  
  // Update dashboard
  dashboard.update({
    healthScore: result.health_score,
    errorRate: result.summary.error_count / result.summary.total_logs,
    topPatterns: result.patterns.slice(0, 5)
  });
}

setInterval(updateHealthDashboard, 60000); // every minute

Evolution Strategy Comparison

// Compare different evolution strategies
const logs = await getProductionLogs();

const strategies = ['balanced', 'innovate', 'harden', 'repair-only'];

const results = await Promise.all(
  strategies.map(strategy =>
    claw0x.call('capability-evolver', {
      action: 'evolve',
      logs,
      strategy
    })
  )
);

// Compare estimated improvements
for (let i = 0; i < strategies.length; i++) {
  console.log(`${strategies[i]}: ${results[i].estimated_improvement}`);
}

// Choose best strategy for current situation
const best = results.reduce((a, b) => 
  parseFloat(a.estimated_improvement) > parseFloat(b.estimated_improvement) ? a : b
);

How It Works — Under the Hood

Capability Evolver is a deterministic analysis engine that processes structured log data and produces actionable diagnostics. No LLM is involved �?the analysis is rule-based, which means results are reproducible and fast.

Analysis Engine

The core engine processes log entries through several analysis passes:

1. Pattern detection �?logs are grouped by context (file/module) and level (error/warn/info/debug). The engine looks for:

   • Repeated errors �?the same error message appearing multiple times indicates a systemic issue, not a transient failure
   • Error cascades �?errors in module A followed by errors in module B within a short time window suggest a dependency chain failure
   • Regression signals �?errors that appear after a period of clean logs suggest a recent change broke something
   • Inefficiency patterns �?excessive warn-level logs or repeated retries indicate performance issues

2. Health scoring �?a system health score (0�?00) is computed based on:

   • Error rate (errors / total logs)
   • Error diversity (unique error messages / total errors)
   • Warn-to-error ratio
   • Time distribution (clustered errors score worse than spread-out errors)

3. Recommendation generation �?based on detected patterns, the engine generates specific, actionable recommendations. These aren't generic advice �?they reference the actual files, error messages, and patterns found in your logs.

Evolution Strategies

When using the evolve action, you can choose a strategy that shapes the recommendations:

Strategy	Focus	Best For
auto	Balanced based on health score	Default �?let the engine decide
balanced	Equal weight to reliability and features	Stable systems with moderate issues
innovate	Prioritize new capabilities	Healthy systems ready to grow
harden	Prioritize reliability and error reduction	Systems with frequent failures
repair-only	Fix critical issues only	Systems in crisis

Evolution Proposals

The evolve action produces structured improvement proposals with:

• A unique evolution_id for tracking
• Prioritized recommendations with category labels (reliability, performance, architecture)
• Risk assessment (how risky is each proposed change)
• Estimated improvement (projected health score after implementing recommendations)

Why Deterministic (Not LLM)?

• Reproducible �?same logs always produce the same analysis. Critical for debugging and auditing.
• Fast �?sub-100ms processing. No API call to an AI provider.
• No hallucination risk �?the engine only reports patterns it actually found in the data.
• Cost-effective �?pure computation, no token costs.

The tradeoff: the engine can't understand semantic meaning in log messages the way an LLM could. It relies on structural patterns (frequency, timing, severity) rather than understanding what the error message means in context.
