The Agent Stack #014 — Wednesday Stack The AI gateway everyone trusts just got compromised. LiteLLM, used by thousands of developers to manage model API calls, fell victim to credential-stealing malware via their security compliance partner Delve. This isn’t just another breach story—it’s a wake-up call about the fragile infrastructure we’re building AI agents on. What Actually Happened LiteLLM serves as a proxy layer between your applications and model providers like OpenAI, Anthropic, and Cohere. Think of it as the plumbing that routes your API calls, handles rate limiting, and logs usage. The ishaan-jaff/litellm repo has 13.7k stars and gets downloaded millions of times monthly. ...

The Agent Stack #009 — Wednesday Stack Building reliable AI agents means your tools can’t crash when the LLM does something unexpected. Which happens constantly. I’ve been testing ToolGuard, the “pytest for AI agent tool calls” that launched this week. The premise is simple: fuzz your Python tool functions with edge cases before your agent calls them in production. Missing JSON keys, type mismatches, 10MB payloads, null values — all the creative ways LLMs break your assumptions. ...

The Agent Stack #004 — Wednesday Stack Anthropic just shipped Claude Cowork plugins for finance, engineering, and design work. This isn’t another AI assistant announcement. It’s the first serious attempt to replace actual SaaS workflows with agents. I’ve been testing the Google Workspace integration for three days. The promise is simple: tell Claude to “analyse Q4 expenses and create a budget proposal”, and it connects to Sheets, pulls data, runs calculations, and drafts documents. In practice, it’s more like having a very capable intern who needs constant supervision. ...
