Week 2: Giving Our Agents Memory — and Hands
One week after standing up the core architecture, we taught our agents to remember what they learn, fetch the right tools on demand, and delegate work like a growing org chart. Here’s what shipped, what surprised us, and where the next sprint is heading.
1. Vector Stores = Long-Term Memory
Implemented OpenAI vector store API to hold every file, prompt, and decision as searchable embeddings.
Batch uploads & JSON logging keep inserts fast and traceable.
File-aware retrieval lets an agent cite the exact doc it saw three tasks ago—no token-wasting “remind me” prompts.
Why we should care: memory lowers inference cost and makes each agent smarter the longer it runs.
2. Tool Management: Zapier Becomes the Agent’s Hands
Database of tools + attachment system means every agent knows which apps (Sheets, Webhooks, socials, etc.) it can reach.
Structured JSON “tool requirements” streamline calls to Zapier’s new Assistants API.
Validation layer blocks bad payloads before they hit production webhooks.
Outcome: agents can now spin up a real-time competitor-analysis workflow with zero human wiring.
3. Smarter Hierarchies, Cleaner Delegation
Fixed sub-agent creation and enabled any agent to spawn specialists.
External tool requests propagate automatically, so a Finance agent can ask Ops to fetch data without PM hand-offs.
All agents can now have sub-agents—the org chart draws itself.
4. Stability & Observability Upgrades
Squashed our infamous “double-CEO” bug.
Sanitised the repo (IDE cruft gone, tighter .gitignore).
Google Docs logging plus richer structured logs give us trace-level insight when something misbehaves.
5. Hard-Won Lessons
What Happened | Takeaway | Adjustments |
|---|---|---|
Vector store inserts slowed during large file batches | Embeddings need throttling per rate-limit window | Added batch size auto-tuner |
Some agents asked for tools they didn’t have | Capability awareness wasn’t stored | Tools now written to agent memory at creation |
Delegation loops stalled when a sub-agent failed silently | Missing error bubbles | Added retry + alert hooks |
6. Roadmap for Week 3
Ship Zapier actions in prod so agents can push data, not just request it.
Conversation memory & collaborative delegation—agents share context instead of repeating themselves.
Compare old vs. new summary quality to quantify vector-store impact.
Full agent orchestration layer to schedule, monitor, and auto-heal multi-agent workflows.
“Vector stores are our agents’ memory, Zapier their hands, and collaboration their mind.” — Entonomy Engineering Team
We’re still early, but the rails for autonomous, revenue-producing businesses are getting sturdier every sprint. Stick around—next week the agents start shipping Zapier-powered deliverables to real endpoints.
