Vercel deleted 80% of its agent’s tools—and the agent got better
Nate B Jones argues that adding more context/memory/tools isn’t how agents improve. Vercel studied a top rep’s actual workflow (filtering inbound messages, qualifying leads, researching companies, drafting responses), built an agent around those real patterns rather than idealized processes, and refined it afterward—with human review still in the loop for judgment-critical decisions. Counterintuitive but effective: less tool sprawl → more reliable outcomes

Don’t build more AI agents until you watch this (YouTube)
A video essay on why most agent projects fail by overbuilding upfront. Vercel’s case study is highlighted as a cleaner approach to agent design that prioritizes observed workflows and surgical scope before adding integrations, autonomy, or memory extensions.

Structured Summary by Topic
Product Launches & Platform Updates
- Vercel’s Agent Optimization — Vercel removed most tools from their agent and observed better performance, validating a “less is more” approach to agentic design. The team reverse-engineered the workflow of top performers rather than designing an idealized system, then deployed with human-in-the-loop review for non-trivial decisions:
Research & Analysis
- Agent Design Patterns — Current thinking challenges conventional wisdom about agent capabilities and suggests that scope discipline (removing tool surface area, focusing on high-confidence patterns) yields more reliable results than maximalist architectures. Vercel’s experiment is presented as evidence that studying real workflows produces better agents than prescribing them from first principles:
Content & Video Essays
- Nate B Jones — “Don’t build more AI agents until you watch this” (YouTube transcript available)
A comprehensive video on agent design philosophy, using Vercel’s approach as the core case study. Transcript confirms discussion of filtering inbound messages, lead qualification workflows, research tasks vs judgment calls, and iterative refinement after initial deployment:
Tooling & Engineering Practices
- Workflow Reverse-Engineering for Agents — Vercel’s method involved watching one of their best sales representatives handle an “unusually messy inbox” (spam, real leads, support questions mislabeled as inbound sales, accounts worth different levels of effort), identifying what the rep ignored vs answered, how they validated serious opportunities, when research preceded a reply, and where human judgment remained necessary. The agent was built to replicate those exact patterns—not an idealized workflow but observed behavior. Human review remains in place for decision points requiring judgment:
