You now have Tessl installed and configured. Here's what you have:

**✓ Tessl CLI** - Installed and authenticated as ${username}

**✓ skill-builder Skill** - A working example in \`examples/skill-builder/\` that helps you create more skills

**✓ Quality Checks Passed**
- Skill Review: ${reviewResults.score}/100 (structure ✓)
- Tile Eval: ${tileEvalResults.passed}/${tileEvalResults.total} scenarios passed (function ✓)
${repoEvalResults ? `- Repo Eval: ${repoEvalResults.passed}/${repoEvalResults.total} scenarios passed (integration ✓)` : '- Repo Eval: skipped (optional)'}

## What You Can Do Now

1. **Try skill-builder:** Use it to create your first skill
2. **Explore the registry:** Run \`tessl skill search\` to see what's available
3. **Read the docs:** Visit https://docs.tessl.io for more

## What You Learned

- **Skills** are tested, versioned agent capabilities
- **Review** validates structure before function
- **Evals** test real behavior with scenarios
- **The quality pipeline** ensures production readiness

Setup took ${duration} seconds. Happy building! 🚀

**Completed:** ${new Date().toISOString()}
**Duration:** ${duration} seconds
**User:** ${username}

## Execution Summary

All onboarding steps completed successfully.

## Results

### Skill Review
- Score: ${reviewResults.score}/100
- Status: ${reviewResults.score >= 80 ? 'Passed' : 'Needs improvement'}

### Tile Eval
- Scenarios: ${tileEvalResults.total}
- Passed: ${tileEvalResults.passed}
- Failed: ${tileEvalResults.total - tileEvalResults.passed}
- Pass Rate: ${Math.round((tileEvalResults.passed / tileEvalResults.total) * 100)}%

${repoEvalResults ? `### Repo Eval
- Scenarios: ${repoEvalResults.total}
- Passed: ${repoEvalResults.passed}
- Pass Rate: ${Math.round((repoEvalResults.passed / repoEvalResults.total) * 100)}%
` : '### Repo Eval\nSkipped (optional step)\n'}

## Artifacts Created

- \`examples/skill-builder/\` - Example skill
- \`.tessl/evals/\` - Repo eval scenarios
- \`onboarding-summary.md\` - Human summary
- \`onboarding-report.md\` - This report

## Next Steps

User should:
1. Try skill-builder to create a new skill
2. Explore the registry
3. Read documentation

Agents should:
- Suggest using skill-builder for new skills
- Remember user understands quality pipeline
- Maintain review ≥80%, eval ≥80% standards
