Agent Builder — Session Context

What this project does

Design, build, and test autonomous N8N agents on server-01 sandbox before any production promotion. First two agents: Agent Builder Agent + N8N Builder Agent.

Scheduled work (2026-06-16, running behind — started ~6:38 PM)

1. Vision Alignment Grill-Me — Agent Builder + N8N Builder vision + testing methodology
2. Agent Builder Agent — Deploy + Test (server-01 sandbox)
3. N8N Builder Agent — Deploy + Test (server-01 sandbox)

Architecture

• Agents run as N8N workflows on server-01 (n8n-sandbox, port 5679)
• Sandbox-first: all agents tested in sandbox before any production promotion
• server-01 sandbox stack: n8n-sandbox, postgres-sandbox, vault-sandbox, bitwarden-bridge-sandbox, vaultwarden-sandbox
• Sandbox N8N API key: prod Vault at secret/sandbox/n8n
• Sandbox reachable at 192.168.1.90

Key decisions (set during vision grill-me — 2026-06-16)

• Agent Builder Agent: builds claude_agent and script types — Ollama (llama3.1:8b) does the building, claude -p is overseer/validator
• N8N Builder Agent: builds n8n_automation types — Ollama generates workflow JSON, imports via N8N API, assigns credentials
• automation_ideas schema changes needed: rename description → task_description (full structured spec), add type (n8n_automation/claude_agent/script), add builder_status
• New agent_test_results table needed in api_business DB
• Sandbox must mirror production: AppRole, Vaultwarden, bridge all configured before any agent deploys
• Promotion = user approval required after all 4 test levels pass (not auto-promote in v1)
• Dedicated backfill session needed for all 48 existing automation_ideas rows (type + task_description)
• claude -p uses SDK credits (Pro = $20/month hard limit) — use sparingly, Ollama does the heavy lifting
• Local model: llama3.1:8b already pulled on server-01 (4.9GB, fits in RTX 2060 Super 8GB VRAM)

Testing methodology

• Four levels: Structure → Deployment → Smoke → Assertion
• LLM outputs validated on structure/side-effects only, never exact string match
• All results logged to agent_test_results table
• NTFY notification on pass and fail
• Full methodology: .claude/playbook_testing_methodology.md

Agents

Agent Builder Agent

• Status: pending — prereqs not complete
• Purpose: Receives automation spec from automation_ideas DB, uses Ollama to build claude_agent or script type automations, deploys to sandbox, runs automated tests, notifies user for promotion approval
• Builds: claude agents (via claude -p) and Python scripts (Docker containers)

N8N Builder Agent

• Status: pending — prereqs not complete
• Purpose: Receives automation spec from automation_ideas DB, uses Ollama to generate N8N workflow JSON using n8n_automations playbook as context, imports to sandbox N8N via API, assigns credentials, runs automated tests
• Will be used to build: id=12 (Media Pipeline Learning), id=7 (Friday Research Session Prep)

Related personal_projects DB rows

• id=4: N8N Workflow Builder Script (pending, weekend_block1)

Prereq checklist (must complete before any agent deployment)

• Schema: rename automation_ideas.description → task_description, add type, add builder_status, add priority
• Create agent_test_results table in api_business
• Sandbox Vault: set up AppRole auth method (credentials at /opt/appdata/docker/docker-compose/vault/approle/ on server-01)
• Sandbox Vault: store sandbox N8N API key at secret/sandbox/n8n (key name: claude-sandbox, verified working)
• Verify sandbox Bitwarden bridge ↔ Vaultwarden sandbox end-to-end (bridge on port 8080, returns [] for empty vault — correct)
• Write Agent Builder Agent playbook → .claude/playbook_agent_builder_agent.md
• Write N8N Builder Agent playbook → .claude/playbook_n8n_builder_agent.md
• Backfill session: COMPLETE. All pending rows reviewed across sessions 1-3. Blocked rows verified (32, 30, 13, 27, 23, 24, 22, 2, 21, 35, 36, 55, 56, 18 — all still blocked, no changes without proper review). Admin done: id=28 → p10, id=57 keeps p9, dummy row id=16 deleted. Session 3 (2026-06-18) final batch: ids 47, 48, 31, 26, 54.
  • id=25: type→n8n_automation, status→pending (8b model lifts hardware block), full rewrite with SDK credit model, model router + cost gate + subscription monitor, model_effort_routing_log training table
  • id=17: type→n8n_automation, expanded with token_waste_patterns DB table (evolution mechanism), JSONL-based detection, NTFY claude-audit gate, fan-out plan noted
  • id=42: expanded with hybrid trigger (Claude flags + asks), B+C output (DB + wrap-up surface), human gate permanent, hard boundary (business research = id=55 only), voice note
  • id=46: type→n8n_automation, Hermes ref removed, playbook_schema.md bootstrap design, three risk tiers, id=52 detector/id=46 executor boundary, fan-out plan noted
  • id=43: Vault AppRole required (youtube-oauth-script, new policy), vault_registry entries, port 8085 (8080 reserved for bridge), dynamic Vault IP, write verification, token refresh companion
  • id=45: hard dep on id=43 (Vault auth), niche_saturation_thresholds DB table (evolution), niche_check_results table, three-signal output (saturated/viable/unclear), id=18 stage 2 integration

New automation_ideas rows added 2026-06-18 (ids 59–67)

• id=59: Claude Audit Research Prep (n8n_automation, p12) — Saturday briefing for 12:45 PM review
• id=60: Claude Audit Topic Detector (n8n_automation, p11) — detects new topics → claude_config.audit_topics; must build first
• id=61: Claude Config Dev Work Scheduler (n8n_automation, p13) — Sunday session prep from Saturday decisions
• id=62: Monthly Security Audit (n8n_automation, p7) — first Monday of month, 7-area audit → security_audit DB
• id=63: Security Patch Backlog Handler (claude_agent, p7) — works security_audit.findings; Vault/prod always human-gate
• id=64: Business Projects Worker (claude_agent, BLOCKED p29) — 12:45–4:30 PM daily; blocked pending business_projects schema
• id=65: Personal Projects Worker (claude_agent, BLOCKED p29) — 5:30–8:00 PM daily; blocked pending personal_projects schema
• id=66: Media Pipeline Project Worker (claude_agent, BLOCKED p29) — Wednesday 5:30–8:00 PM; blocked pending id=65 + scope
• id=67: N8N Builder Agent (claude_agent, p2, ready_to_build) — builds all n8n_automation rows; deploy Monday June 22 alongside id=24

Readiness check — COMPLETE (2026-06-18 evening)

All 8 prereq checklist items verified live on server-01:

• Vault AppRole: token acquired, N8N secret readable
• N8N sandbox API: returns 200 with real key
• Bridge /items: returns [] (correct for empty sandbox vault)
• Ollama: llama3.1:8b loaded
• agent_test_results table: confirmed correct schema + FK

June 20 (Saturday) — Session progress

id=57 partially complete. Carried over from June 19 (sick day).

id=57 — DONE this session:

• Production N8N migrated from primary server → server-01 port 5678
• Vault-backed start.sh: secrets pulled from production Vault at runtime, nothing on disk
• n8n-server01 AppRole created in production Vault (scoped to secret/data/n8n read-only)
• Stale root token in Bitwarden replaced — regenerated via generate-root (3/5 keys), updated, revoked
• Traefik static route live: /traefik/dynamic/n8n.yaml → 192.168.1.90:5678
• Rollback procedure documented + all 4 checks passed: /opt/appdata/docker/docker-compose/n8n/ROLLBACK.md
• claude-policy extended: AppRole management + sys/generate-root paths added

id=57 — REMAINING (next session):

• Sandbox Vaultwarden population — bw CLI approach FAILED (version mismatch); use Vaultwarden REST API directly (id=70 tracks implementation); 53 infra items, dummy values, no production data
• N8N sandbox credentials (-sandbox suffix names)
• Sudo bridge deploy on server-01 (Phase 2) — then disable NOPASSWD:ALL in /etc/sudoers.d/administrator on server-01

id=51 — NOT STARTED. Scope locked:

• Option B zero-exposure proxy: agent sends "run X using secret Y", proxy executes + injects secret, returns result only
• Must be live before builder agents deploy

June 20 Session 2 (continuation)

• Sandbox Vault auto-unseal deployed: vault-sandbox-unseal.sh + vault-sandbox-watch-unseal.sh + 2 systemd services, unsealed and verified
• Sandbox Vault AppRole mirror: 9 policies + 5 roles recreated from production (claude-code, claude-policy, n8n, n8n-outreach-policy, n8n-policy, n8n-rotation-policy, n8n-scheduling-policy, n8n-server01-policy, nextcloud-init)
• Production Bitwarden audit: 294 items total, 53 infra items identified (all username/password, some with notes)
• Sandbox Vaultwarden population BLOCKED: bw CLI 2026.5.0 WASM crypto error on create — use Vaultwarden REST API next session (id=70)
• sudo bridge NOT on server-01: server-01 has NOPASSWD:ALL; plan = deploy bridge first (Phase 2), then disable NOPASSWD
• ids added: 69 (Vaultwarden Version Monitor, p16), 70 (Sandbox Vaultwarden Seeder, p17)
• feedback_bw_cli_vaultwarden_create.md added to docker MEMORY.md

June 22 (Monday) — Builder Agents (extended session)
