Welcome to Chapter 4: Agents, Skills, and Command Orchestration. In this part of Everything Claude Code Tutorial: Production Configuration Patterns for Claude Code, you will build an intuitive mental model first, then move into concrete implementation details and practical production tradeoffs.
This chapter focuses on day-to-day orchestration patterns.
- route tasks through commands with minimal ambiguity
- choose the right specialist agent for each task class
- activate supporting skills for quality and speed
- structure complex workflows into deterministic phases
planbefore execution- delegate to specialized agents during implementation
- run review/security passes before merge
- close with verification and learnings capture
/plan -> /tdd -> /code-review -> /verify -> /learn
You now have a practical command/agent orchestration baseline.

The summarizeCategoryScores function in scripts/harness-audit.js handles a key part of this chapter's functionality:
}
function summarizeCategoryScores(checks) {
const scores = {};
for (const category of CATEGORIES) {
const inCategory = checks.filter(check => check.category === category);
const max = inCategory.reduce((sum, check) => sum + check.points, 0);
const earned = inCategory
.filter(check => check.pass)
.reduce((sum, check) => sum + check.points, 0);
const normalized = max === 0 ? 0 : Math.round((earned / max) * 10);
scores[category] = {
score: normalized,
earned,
max,
};
}
return scores;
}
function buildReport(scope) {
const checks = getChecks().filter(check => check.scopes.includes(scope));
const categoryScores = summarizeCategoryScores(checks);
const maxScore = checks.reduce((sum, check) => sum + check.points, 0);
const overallScore = checks
.filter(check => check.pass)
.reduce((sum, check) => sum + check.points, 0);
const failedChecks = checks.filter(check => !check.pass);
const topActions = failedChecksThis function is important because it defines how Everything Claude Code Tutorial: Production Configuration Patterns for Claude Code implements the patterns covered in this chapter.
The buildReport function in scripts/harness-audit.js handles a key part of this chapter's functionality:

function buildReport(scope) {
const checks = getChecks().filter(check => check.scopes.includes(scope));

const maxScore = checks.reduce((sum, check) => sum + check.points, 0);
const overallScore = checks
.filter(check => check.pass)
.reduce((sum, check) => sum + check.points, 0);
const failedChecks = checks.filter(check => !check.pass);
const topActions = failedChecks
.sort((left, right) => right.points - left.points)

The printText function in scripts/harness-audit.js handles a key part of this chapter's functionality:
}
function printText(report) {
console.log(`Harness Audit (${report.scope}): ${report.overall_score}/${report.max_score}`);
console.log('');
for (const category of CATEGORIES) {
const data = report.categories[category];
if (!data || data.max === 0) {
continue;
}
console.log(`- ${category}: ${data.score}/10 (${data.earned}/${data.max} pts)`);
}
const failed = report.checks.filter(check => !check.pass);
console.log('');
console.log(`Checks: ${report.checks.length} total, ${failed.length} failing`);
if (failed.length > 0) {
console.log('');
console.log('Top 3 Actions:');
report.top_actions.forEach((action, index) => {
console.log(`${index + 1}) [${action.category}] ${action.action} (${action.path})`);
});
}
}
function showHelp(exitCode = 0) {
console.log(`

process.exit(exitCode);
}
