Capability Evolver

Local skill by Claw0x — runs entirely in your OpenClaw agent.

Runs locally. No external API calls, no API key required. Complete privacy.

Analyze agent runtime logs, detect patterns, compute health scores, and generate structured improvement proposals. Pure deterministic logic — no LLM, no external dependencies.

Quick Reference

When This Happens	Use Action	What You Get
Agent keeps failing	`analyze`	Error patterns + health score
Same error repeats	`analyze`	Root cause identification
Need improvement plan	`evolve`	Prioritized recommendations
System health check	`status`	Health score + summary
Post-deployment review	`analyze`	Regression detection
Fleet-wide diagnostics	`analyze` (batch)	Cross-agent patterns

Why deterministic? Reproducible results, no hallucination risk, sub-100ms processing, zero token costs.

Prerequisites

None. Just install and use.

5-Minute Quickstart

Step 1: Install (30 seconds)

openclaw skill add capability-evolver

Step 2: Analyze Your First Logs (1 minute)

const result = await agent.run('capability-evolver', {
  action: 'analyze',
  logs: [
    {timestamp: '2025-01-15T10:00:00Z', level: 'error', message: 'ETIMEDOUT', context: 'payment-api.ts'},
    {timestamp: '2025-01-15T10:01:00Z', level: 'error', message: 'ETIMEDOUT', context: 'payment-api.ts'},
    {timestamp: '2025-01-15T10:02:00Z', level: 'error', message: 'ETIMEDOUT', context: 'payment-api.ts'}
  ]
});

Step 3: Get Actionable Insights (instant)

{
  "patterns": [
    {
      "type": "repeated_error",
      "severity": "high",
      "description": "ETIMEDOUT appeared 3 times in payment-api.ts",
      "affected_contexts": ["payment-api.ts"]
    }
  ],
  "health_score": 45,
  "recommendations": [
    "Add timeout configuration to payment-api.ts",
    "Implement retry logic with exponential backoff",
    "Monitor payment API response times"
  ]
}

Step 3: Generate Evolution Plan (instant)

const evolution = await agent.run('capability-evolver', {
  action: 'evolve',
  logs: result.logs,
  strategy: 'harden'
});

Done. You now have a prioritized improvement roadmap, all processed locally.

Real-World Use Cases

Scenario 1: Production Incident Response

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

Solution:

Export last 1000 log entries
Run analyze action
Get error patterns and cascades
Identify root cause in minutes

Example:

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

Schedule daily log analysis
Generate evolution proposals
Review and apply recommendations
Track improvement over time

Example:

// Cron job: every day at 2am
async function dailyEvolution() {
  const logs = await getLast24HoursLogs();
const evolution = await agent.run('capability-evolver', {
action: 'evolve',
logs,
strategy: 'balanced'
});
// Store recommendations for review
for (const rec of evolution.recommendations.filter(r => r.priority === 'critical')) {
await db.recommendations.create({
title: 
${rec.category}: ${rec.description},
priority: rec.priority,
affected_files: rec.affected_files,
approach: rec.suggested_approach
});
}
// Track health score trend
await db.metrics.create({
date: new Date(),
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:

Aggregate logs from all agents
Batch analyze to find common patterns
Fix once, deploy to all agents
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:

Analyze logs from staging environment
Compare health score to production baseline
Block deployment if health score drops
Catch regressions before production

Example:

// Pre-deployment health check script
async function preDeploymentCheck() {
  const stagingLogs = await fetchStagingLogs();
const result = await agent.run('capability-evolver', {
action: 'analyze',
logs: stagingLogs
});
const BASELINE = 75;
if (result.health_score < BASELINE) {
console.error(
Health score ${result.health_score} below baseline ${BASELINE});
console.error('Critical patterns:', result.patterns.filter(p => p.severity === 'critical'));
process.exit(1);
}
console.log(✓ Health check passed: ${result.health_score});
}
// Result: Zero regression-related incidents in 6 months

Integration Recipes

OpenClaw Agent

// Analyze logs after each run
agent.onComplete(async () => {
  const logs = agent.getRecentLogs();
const analysis = await agent.run('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

def analyze_agent_health(logs):
    result = agent.run("capability-evolver", {
        "action": "analyze",
        "logs": logs
    })
return {
    &quot;health_score&quot;: result[&quot;health_score&quot;],
    &quot;patterns&quot;: result[&quot;patterns&quot;],
    &quot;recommendations&quot;: result[&quot;recommendations&quot;]
}

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 result = await agent.run('capability-evolver', {
action: 'analyze',
logs
});
// 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 =>
agent.run('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:

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
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)
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.
