AI Agent CLI

A CLI coding agent built from scratch, version by version — implementing a ReAct-style agent loop, tool calling (bash execution, planning, clarifying questions), human-in-the-loop approval gates for risky actions, persistent cross-session memory, context compaction/summarization, and E2B-sandboxed command execution.

Engineered a production-style agentic loop with guardrails, persistent memory, and sandboxed execution to safely run autonomous multi-step coding tasks.
