# Episode: Cursor Composer 2, AgentMail, design bash tools et le futur des warehouses
## Episode Summary
In this news-focused episode, Julien and his co-host dive into the latest developments in AI engineering, from the Cursor Composer 2 controversy involving Kimi licensing to innovative approaches like bash-style interfaces for AI agents. They explore practical tools like AgentMail for isolating agent communications, discuss the shift from function calling to CLI-style commands, and debate whether warehouses like Snowflake and Databricks can maintain relevance in an agent-first world where OpenAI and Anthropic are positioning themselves as the new cloud platforms.
## Key Topics Discussed
- **Cursor Composer 2 licensing drama** - Controversy over potential unlicensed use of Kimi 4.2.5 model and performance comparisons with Claude Opus
- **Cursor's Instant Grep** - New search algorithm dramatically faster than ripgrep (13ms vs 16 seconds on large codebases)
- **AgentMail** - Temporary email addresses for AI agents to maintain isolation and security
- **Bash-style interfaces for agents** - Moving away from function calling to Unix-style commands for agent tools
- **Vercel's Bash library** - TypeScript implementation with multiple file system types (in-memory, overlay, read-write, mountable)
- **OpenAI acquiring Astral (UV/Ruff)** and Anthropic acquiring Bun - Big AI companies becoming the new cloud providers
- **The future of data warehouses** - Whether Snowflake, Databricks, and BigQuery can adapt to an agent-driven world
- **UI testing as the remaining bottleneck** - LLMs struggling with visual interface testing and location tasks
- **DBT Fusion going GA** - Static SQL validation for better agent loops in analytics
## Notable Quotes
> "I don't want to give access to my mailboxes to my agents. But the strategy to get around that is just to give temporary email addresses to agents for each project... I found the idea quite brilliant. It's really oriented for agents."
> "OpenAI and Anthropic become the new cloud of this age. I think it's them who are going to be the AWS, the GCP and the Azure of this age... They're basically creating the whole ecosystem so that you just have to do cloud code or co-work, deploy, and then it goes to Anthropic."
> "The more you talk to people, the more everyone is literally doing exactly [the same thing]. When we work on agents, everyone recreates the system, the tools, the file system, the orchestration, the browser screenshots, the memory, the prompts, the streaming, the test results, the logs."
