🔄 Rekap & Persiapan Akhir
Hari terakhir dimulai dengan rekap singkat materi Day 4:
| Konsep | Poin Kunci |
|---|---|
| Context Engineering | Seni mengelola input token agar output konsisten dengan business goal |
| Sub-agents | Reusable, testable, hemat context — tapi batasi kreativitas agent |
| Anti-patterns | Human trap, solution-focused, content-generation-as-goal |
| Evaluasi | Business problem → metrik → testing ketat → R&D empiris |
🔑 Pengingat Terakhir: LLM menghasilkan konten yang plausible — tugas AI engineer adalah membuatnya accurate melalui testing, metrik, dan structured outputs.
🔧 Konversi Sub-agents ke Sub-workflows
Sebelum membangun orchestrator agent, kedua sub-agent dari Day 4 harus dikonversi menjadi sub-workflows yang siap dipanggil.
SDR Sub-agent
SEBELUM: SESUDAH:

│ Manual │ │ When Executed by Another │
│ Trigger │ ──▶ Agent │ Workflow │ ──▶ Agent
│ (tombol) │ │ │
└──────────────┘ │ Input: Accept All Data │
└──────────────────────────┘Langkah:
- Hapus trigger manual
- Tambah trigger → "When executed by another workflow"
- Input Data Mode → Accept All Data
- Save → Publish (wajib agar bisa dipanggil!)
RevOps Sub-agent
SEBELUM: SESUDAH:

│ │ │ │
└──────────────┘ │ Input Schema: │
│ ├── field: sales_lead_ │
│ │ description │
│ └── type: string │
└──────────────────────────┘Langkah Tambahan untuk RevOps:
- Tambah Input Schema → field
sales_lead_description(string) - Update AI Agent prompt → expression
{{ $json.sales_lead_description }} - Tambah Sticky Notes untuk dokumentasi visual (Parse Data + Store to Pipedrive)
- Save → Publish
💡 Sticky Notes adalah praktik baik untuk membuat workflow bisa dibaca oleh orang lain — label setiap section dengan deskripsi singkat.
🤖 Business Development Manager Agent
Agent utama pertama! Ini adalah orchestrator yang mengoordinasi ketiga sub-agent.

System Prompt
You are the sales manager for an accounting software firm at CTI.
You are provided with the ICP for an ideal prospect.
You must carry out these steps:
1. Use your Prospecting Subagent tool ONCE to search online for leads,
providing a query based on the ICP.
2. For EACH identified prospect, use your RevOps Subagent tool repeatedly
to store the information in the CRM database.
Use the tool ONCE for EACH prospect.
3. Use your SDR Subagent tool ONCE — this tool will retrieve everyone
in Pipedrive and draft an outbound sales email for all of them.
Then reply with a summary of the outcome.Structured Output
json
{
"success": true,
"summary": "A concise description of what happened"
}⚠️ Catatan Desain: Data prospect dikembalikan sebagai natural language dari Prospecting, lalu di-parse ulang oleh RevOps ke JSON. Ini sengaja untuk fleksibilitas — banyak sumber data di masa depan bisa menggunakan format berbeda. Pendekatan lebih ketat: buat input terpisah per field (name, company, role, email).
🐛 Debugging & End-to-End Test
Tiga bug ditemukan saat pengujian pertama:
Bug #1: RevOps Input Field Salah
❌ SALAH: Field "sales_lead_description" diisi dengan deskripsi statis
→ Agent selalu mengirim teks yang sama ke RevOps
✅ BENAR: Field "sales_lead_description" → "Set by model"
→ Deskripsi pindah ke field "Description" yang terpisahBug #2: IF Node — Boolean vs String
❌ SALAH: String comparison → "is $json.output.success equal to 'true'?"
→ Membandingkan boolean dengan string "true" → selalu false!
✅ BENAR: Boolean comparison → "is $json.output.success TRUE?"
→ Evaluasi boolean yang benarBug #3: RevOps — Email Field Kosong
❌ SALAH: Create Person node tidak menyertakan email
→ SDR tidak bisa draft email (alamat kosong)
✅ BENAR: Tambah field "email" di Create Person
→ Expression: {{ $('AI Agent').item.json.output.email }}
→ Republish workflow setelah fix!End-to-End Test Berhasil! ✅

└──────────┘Mengapa Webhook, Bukan Sub-workflow?
Berbeda dari sub-agent sebelumnya, kali ini trigger menggunakan Webhook (bukan "When executed by another workflow") karena sub-agent ini akan dipanggil oleh ElevenLabs Voice Agent — yang berkomunikasi via HTTP POST, bukan melalui n8n internal.
