farmer is an npm package that intercepts tool-call permission requests from AI coding agents and routes them to a mobile-friendly dashboard. Instead of watching a terminal scroll as Claude Code or another agent quietly runs shell commands, you get a swipe-card view on your phone where each pending tool call shows the command, its arguments, and the agent's reasoning — and you approve or deny with a swipe. The architecture is deliberately simple: farmer acts as a hook in the agent's tool-call loop, holds execution until you respond, then forwards your decision back. It ships with a Claude Code adapter out of the box and a documented adapter interface for other agents. The mobile UI is a PWA, so there's nothing to install — just navigate to the local server address in Safari or Chrome. For developers running long agentic sessions — overnight refactors, automated test generation, or repo-wide migrations — farmer fills a real gap. Current tools either block the terminal or run with blind trust. farmer offers a middle path: human-in-the-loop control without requiring you to be physically at your machine.

Warp started as a beautiful Rust-built terminal with AI autocomplete, and five years later it's become an Agentic Development Environment (ADE) — and as of today, it's fully open source under AGPL. The company is open-sourcing its client codebase with OpenAI as the founding sponsor, with GPT-5.5 powering the agentic workflows that manage community contributions through their cloud orchestration platform, Oz. Oz is the novel piece: it's Warp's cloud agent system that handles code generation, planning, testing, and implementation in the open-source repo. Community members propose ideas and verify outputs; agents do the implementation. The pitch is "Open Agentic Development" — where even non-technical users can meaningfully contribute to production-grade tools by collaborating with agents rather than writing code directly. With the core client under AGPL and UI framework crates under MIT, Warp joins a growing list of developer tools betting that open-source + AI-powered development is faster than closed-source iteration. The OpenAI sponsorship is eyebrow-raising given Warp supports multiple coding agents including Claude Code — but it signals that even competitors are investing in the open development model.
Reviewer scorecard
“This solves the exact anxiety of kicking off a Claude Code session and then walking away. The swipe-card mobile UI is well thought out — you can do a quick code review of the pending command right from the notification. The adapter interface is clean enough that I could wire it to my own agents in an afternoon.”
“Warp has always had the best terminal UX, and going open-source removes the biggest objection to adopting it in security-conscious environments. The Oz agent-managed development model is experimental, but the AGPL client is immediately useful today.”
“The security model is concerning: you're routing tool-call details through a local WebSocket server that's exposed to your network. Anyone on the same WiFi can potentially see (or intercept) pending commands. There's no auth on the dashboard in v0.1. Fix that before using this on anything sensitive.”
“AGPL is open source with an asterisk — you can read the code, but commercial use requires a commercial license. And letting GPT-5.5 manage your open-source repo sounds exciting until the first time an agent merges a subtly broken PR into main.”
“Human-in-the-loop approval is going to become a compliance requirement for agentic AI in enterprise settings. farmer is ahead of the curve — the patterns it's establishing for mobile-first agent oversight will likely influence how official agent SDKs handle permission gating.”
“Warp's Open Agentic Development model is a preview of how all software will be built: humans proposing direction, agents implementing, community verifying. This isn't just a terminal going open-source — it's a working prototype of post-human software development.”
“I run AI agents to manage my content pipeline and frequently can't be at my desk. The idea of approving file writes and API calls from my phone while I'm at a coffee shop is exactly what I've wanted. The activity feed is a nice touch for auditing what ran while I was away.”
“For technical creators who live in the terminal, Warp's AI features have always been best-in-class. Open-sourcing means the community can extend it with custom integrations — finally a terminal that can grow with whatever workflow you invent next.”
