agentc is a coding agent in C with no libc that fits under 1MB and idles under 1MB of RAM

Shown on HN Oct 7 and inspired by the pi agent, agentc is a static, embeddable coding agent with a TUI, agent loop, tools, MCP, and skills all built as extensions, aimed at tiny hardware or embedding in your own binaries without a Node dependency chain. CI builds cover Linux (x64, arm64, riscv64), Windows (x64, arm64), and macOS arm64; the Rust/C embedding API is still listed as coming in a few days, and the author wants Mac testers.

Claude Code 2.1.295 adds onFailure:block for hooks and Program Status Protocol for terminals

Released Oct 8, command and HTTP hooks can set onFailure: "block" so a hook that can't start, times out, or exits unexpectedly blocks the action instead of letting it through, and terminals that speak OSC 7501 can show whether Claude Code is working, waiting on you, or done. It also raises the MCP tool description cap through tool search from 2,048 to 16,384 characters, backs off remote MCP reconnects after outages, and folds in 2.1.294's fix for prompt/agent hooks that were allowing what they were written to block…
