## 🔎 PHASE 1 — Automation Cost Context Reconstruction **Workflow reconstructed:** Customer Ticket → n8n Trigger → AI Classification → PostgreSQL Lookup → Zendesk Update → Notification **Confirmed from input:** - 50,000 executions/month - n8n is used - OpenAI API is used - PostgreSQL is used - Zendesk is used - Current stated cost: $420/month - Classification quality must be preserved **Missing information:** - Exact token usage - Exact model - API request count - Retry count - Database query count - Infrastructure billing breakdown - Failure rate **Status:** 🟡 Optimization analysis can begin, but exact savings cannot yet be calculated. --- # 💰 PHASE 2 — Cost Model Reconstruction | Cost Category | Usage Driver | Current Cost | Evidence | Opportunity | |---|---|---:|---|---| | AI | 50k ticket classifications | Unknown | Usage supplied | Token/model optimization | | Workflow | 50k executions | Unknown | Usage supplied | Reduce unnecessary executions | | Database | Ticket lookups | Unknown | Architecture supplied | Query optimization/cache | | Zendesk API | Ticket updates | Unknown | Architecture supplied | Deduplication | | Notifications | Workflow notifications | Unknown | Architecture supplied | Conditional notifications | | Total | Monthly automation | $420 | User-supplied | Optimize cost structure | **Important:** The $420 is supplied data, but its internal breakdown is unknown. The skill requires unavailable pricing to remain unquantified rather than fabricated. Pasted text --- # 📊 PHASE 3 — Usage & Execution Analysis Potential execution pattern: **50,000 tickets** → 50,000 AI calls → 50,000 database lookups → 50,000 Zendesk updates Potential concern: - Every ticket appears to trigger the full workflow. - Some tickets may not require AI classification. - Some tickets may have unchanged classification. - Some database lookups may repeat. - Some notifications may be unnecessary. ⚠️ These are **optimization hypotheses**, not confirmed waste. The skill explicitly distinguishes high usage from wasteful usage. Pasted text --- # 🔬 PHASE 4 — Cost Driver & Waste Detection **Potential cost drivers:** 1. 🤖 AI inference on every ticket 2. 🔄 Repeated workflow execution 3. 🗄️ Database lookups 4. 🌐 Zendesk API requests 5. 🔔 Notifications **Highest-priority investigation:** **AI calls → repeated processing → unnecessary API operations** ### Evidence strength - AI call volume: 🟢 High - Duplicate AI calls: 🟡 Unknown - Duplicate API calls: 🟡 Unknown - Unnecessary notifications: 🟡 Unknown - Excessive polling: ⚪ Not identified No component is declared "wasteful" without evidence. Pasted text --- # 🤖 PHASE 5 — AI & Token Cost Optimization ### Option A — Model Routing Simple tickets: **Cheaper model** Complex tickets: **Higher-capability model** Potential benefit: - Lower AI cost for simple classifications. Risk: - Classification quality could decline. Validation: - Compare classification accuracy between current and proposed routing. ### Option B — Reduce Prompt Context Current: **Large ticket context → AI** Proposed: **Relevant ticket fields → AI** Potential benefit: - Lower input-token consumption. Risk: - Missing context could reduce classification accuracy. ### Option C — Deterministic Pre-Filtering Example: If ticket contains known structured category: **Rules → Classification** Otherwise: **AI → Classification** Potential benefit: - Avoid unnecessary AI calls. This follows the skill's requirement to compare expensive models, lower-cost models, deterministic logic, and cached results based on required quality rather than price alone. Pasted text --- # 🔄 PHASE 6 — Workflow Execution Optimization **Current:** Ticket → AI → DB → Zendesk → Notification **Potential optimized flow:** Ticket → Check whether classification is required → If yes → AI → DB → Check whether Zendesk update is actually different → Update only if necessary → Notify only when required ### Potential improvements - Conditional execution - Deduplication - State reuse - Conditional notifications - Avoid unnecessary updates These approaches are explicitly within the workflow optimization framework. Pasted text --- # 🌐 PHASE 7 — API & Third-Party Optimization ### Zendesk Investigate: - Duplicate ticket updates - Unnecessary fields - Repeated requests - Pagination behavior - Retry behavior - Whether event-driven triggers can replace polling ⚠️ No webhook or batching capability is assumed without provider evidence. ### PostgreSQL Investigate: - Repeated queries - Identical lookups - Query frequency - Required fields - Index usage **Priority:** 🟡 Investigate before changing architecture. --- # ☁️ PHASE 8 — Infrastructure Optimization Current infrastructure information is insufficient. Therefore: **CPU:** Unknown **Memory:** Unknown **Runtime:** Unknown **Concurrency:** Unknown **Storage:** Unknown **Network:** Unknown ### Recommendation Collect infrastructure utilization before right-sizing. 🚫 Do not reduce resources simply because infrastructure costs appear high. The skill specifically requires performance and reliability trade-offs to be evaluated before resource reduction.
