claw: a single-shell-script LLM agent that runs on any Linux box with just curl and jq

claw is a pure POSIX shell script (v0, MIT license) that provides a full LLM agent — streaming chat, shell tool calls, rolling memory, and mentor mode — against OpenAI or Anthropic, requiring only sh, curl, and jq with no Node, npm, or Python.

The agent executes shell commands emitted by the model in <shell>…</shell> blocks (YOLO by default; --confirm flag enables prompts), journals prompts and replies to JSONL, and compacts overflow windows into durable session rules and markdown journals. A mentor mode flag toggles a second-pass critique-and-revise loop.

Installation takes 30 seconds: download the script from getclaw.site/claw, set OPENAI_API_KEY or ANTHROPIC_API_KEY, and run; also available live in the browser at linuxontab.com for immediate testing without installation.
