// features Everything you need. Nothing you don't. Built to run in Alpine containers, v86 VMs, and cheap VPS boxes. If it has sh + curl + jq, claw runs.

⚡Shell tool callsThe model emits <shell>…</shell> blocks. claw runs them and feeds results back. YOLO by default; pass --confirm to be prompted.🧠Rolling memoryPrompts and replies are journaled to JSONL. When windows overflow, an LLM compacts them into durable session rules and a per-session markdown journal.🔁Mentor modeA second assistant pass critiques the first answer against your original request, then revises. Toggle with --mentor or /mentor on.🔌Multi-providerSwitch between OpenAI and Anthropic with a single flag. Configurable base URLs let you point at any OpenAI-compatible endpoint.📦Zero dependenciesPure POSIX sh + curl + jq. Runs on busybox ash. No Python, no Node, no package managers. One file. One install.🗂Named sessionsRun isolated sessions with claw -s myproject. Each has its own history, compacted rules, and journal — switch instantly with /load.📚SkillsDrop any .md file into ~/.config/clawlite/instructions/ and it becomes part of the system prompt — project context, tool guides, domain knowledge. No restart needed.

// demo See it in action.

The model uses shell tools to inspect the filesystem and answer in context — all from a single shell script.

<shell>find /var/log -maxdepth 2 -type f -printf '%s\t%T@\t%p\n' \ | sort -rn | head -3 | awk '{printf "%.0fM\t%s\t%s\n", $1/1048576, $2, $3}'</shell> 128M 1714935621 /var/log/syslog 44M 1714849221 /var/log/auth.log 12M 1714762821 /var/log/kern.log

The three largest log files:

syslog 128 MB — last modified ~1 day ago auth.log 44 MB — last modified ~2 days ago kern.log 12 MB — last modified ~3 days ago
