Ant is Anthropic's official command-line interface for the Claude API, launched April 8 alongside Claude Managed Agents. It ships with native Claude Code integration, YAML-based versioning of API resources (prompts, tools, agent configs), streaming support for all Claude models, and direct hooks into the new Sessions and Environments APIs. Think of it as the Vercel CLI equivalent for Claude — deploy, version, and manage your Claude-powered apps from the terminal. The YAML-first design is significant: developers can define agent configurations as code, diff them, roll them back, and deploy them to Managed Agent environments without touching a web UI. The CLI treats Claude prompts and tool definitions as first-class infrastructure artifacts, solving the "prompt drift" problem where what's in your codebase diverges from what's running in production. Ant also integrates with the new advisor-tool beta (also launched April 8) — a pattern that pairs a fast executor model with a higher-intelligence advisor model for mid-generation reasoning. For teams already on the Anthropic platform, Ant is the missing piece that turns the API from "endpoint you POST to" into a full development toolchain.
Developer Tools
Devin for Terminal
Local CLI coding agent that keeps working when you close your laptop

Cognition's Devin for Terminal brings the full autonomous coding power of Devin to your command line. Unlike the browser-based Devin interface, the Terminal version lets you trigger complex engineering tasks from your CLI and continue working — or close your laptop entirely — while Devin executes in the cloud in a persistent session. The key innovation is bidirectional handoff: you initiate locally, Devin Cloud takes over with a persistent execution environment that survives network drops, sleep cycles, and machine switches. This bridges the "last mile" problem of autonomous coding tools — the frustrating requirement to stay connected while a long job runs. Launched April 29, 2026, Devin for Terminal is free to use and signals Cognition's push toward deeper developer workflow integration beyond browser-only interfaces. The clear implication: the future of coding agents isn't a tab you keep open, it's infrastructure that runs in the background.
Reviewer scorecard
“YAML-versioned agent configs that you can diff and deploy from the terminal is exactly what's been missing from the Claude ecosystem. I've been committing prompt strings to git as plaintext — Ant treats them as proper infrastructure. The Managed Agents integration means I can ship an agent to production with one command.”
“The 'keep working when you close your laptop' pitch is exactly right. I've lost countless Devin sessions to network hiccups. Persistent cloud-backed execution from my terminal is the architecture I've wanted since day one. This is how async development should work.”
“Ant is vendor-specific tooling from Anthropic for Anthropic infrastructure. Every piece of your workflow that runs through this CLI is one more lock-in vector. The advisor-tool feature sounds clever but is in beta — the YAML format and agent config schema are likely to change significantly before v1.0.”
“Devin's benchmarks have always been impressive; real-world results sometimes less so. A terminal wrapper doesn't change the underlying model's limitations — it just makes them more convenient to encounter. And Cognition still hasn't fully addressed cost transparency on longer sessions.”
“Anthropic shipping a CLI the same day as Managed Agents is a clear signal: they're building a full developer platform, not just a model API. The advisor-tool pattern — pairing speed and intelligence mid-generation — is architecturally interesting and points toward heterogeneous model routing becoming standard in agentic systems.”
“Devin for Terminal is a preview of where all coding tools are heading: invisible infrastructure that executes while you're away. The terminal is the right interface — it meets developers where they already live. Expect every major coding agent to have a persistent CLI within 6 months.”
“The fact that I can version my Claude prompts like code, see what changed, and roll back if something breaks is massive for anyone building creative tooling on Claude. Prompt drift has killed projects before — treating prompts as deployable artifacts with version history is the right abstraction.”
“Terminal tools aren't for most creators — but for technical creatives who build their own tools, persistent agent execution is a genuine unlock. Kick off a refactoring job, go design something, come back to a finished PR. That's a workflow shift.”
