* fix: prompt caching breaks on Claude Opus 5 and Sonnet 5 shouldPreserveThinkingBlocks() matched modern Claude ids with a hardcoded family list plus /claude-[5-9]/ future-proofing. That regex assumes the generation follows the prefix (claude-5-x), but shipped generation-5 ids place the family in between (claude-opus-5, claude-sonnet-5, claude-mythos-5), so none matched and dropThinkingBlocks flipped to true. Signed thinking blocks were stripped from replayed history, diverging every request and invalidating the Anthropic prompt cache on the default opus/sonnet aliases. Read the generation from the id instead, preserving blocks for generation 4 and newer. This handles both id shapes and matches the idiom already used in audit-extra.sync.ts and live-model-filter.ts. Closes #121251 * fix: correct Claude thinking replay contract Use the canonical Claude model identity and exact Anthropic preservation contract when deciding whether replay may retain prior thinking blocks. Carry deployment metadata through provider-family and fallback paths, and include canonicalModelId in the transcript policy cache key. Release note: Restore prompt-cache reuse for Claude Opus 5 and Sonnet 5 while continuing to strip unsupported Sonnet and Haiku 4.5 thinking history. * refactor: remove unused replay compatibility helper Use the canonical Claude drop predicate at the remaining test call sites and remove the unconsumed preservation export so the dependency/dead-code gate stays clean. * fix: keep Claude replay contract internal Use canonical llm-core identity resolution without exporting a new llm-core capability, avoiding unintended Plugin SDK API drift. --------- Co-authored-by: FullerStackDev <263060202+fuller-stack-dev@users.noreply.github.com>
OpenClaw 🦞 — Your assistant, on your devices, in your chats
OpenClaw is a personal AI assistant that runs on your devices and meets you in the channels you already use. It is designed for a single operator and connects models, tools, messaging channels, and optional companion apps through one Gateway.

Install
The installer supports macOS, Linux, and Windows. It provisions a supported Node.js runtime when needed.
# macOS / Linux / WSL2
curl -fsSL https://openclaw.ai/install.sh | bash
# Windows PowerShell
iwr -useb https://openclaw.ai/install.ps1 | iex
Already manage Node.js? Install the published package instead (Node 22.22.3+, 24.15+, or 25.9+):
npm install -g openclaw@latest
See the installation guide for npm 12 lifecycle-script requirements, Docker, Nix, and other deployment paths.
Quick start
openclaw onboard --install-daemon
openclaw gateway status
openclaw dashboard
Onboarding verifies model access, creates the workspace, and configures the Gateway. The last command opens the Control UI; send a message there to confirm the assistant is working. See the getting started guide for channel setup and troubleshooting.
How it fits together
- The Gateway is the local control plane for sessions, tools, events, and channel connections.
- The Control UI, CLI, and TUI connect to the Gateway.
- Channels bring the assistant to WhatsApp, Telegram, Slack, Discord, Google Chat, Signal, iMessage, and other messaging services.
- Companion apps and nodes add voice, Canvas, camera, screen, and device-local actions on supported platforms.
OpenClaw works with hosted and local model providers. Its tools, skills, and plugins extend what an assistant can do.
Security
Treat inbound messages as untrusted input. DM-capable channels pair unknown senders by default; approve a pairing request with openclaw pairing approve <channel> <code>.
Tools run on the host for the main session unless you configure sandboxing. Read the security guide, exposure runbook, and sandboxing guide before connecting other users or exposing the Gateway remotely.

Development
The repository is a pnpm workspace. Plain npm install at the repository root is not supported.
git clone https://github.com/openclaw/openclaw.git
cd openclaw
pnpm install
pnpm build
pnpm ui:build
See CONTRIBUTING.md for the contribution workflow and the source setup guide for the development loop.
Community
OpenClaw is developed in the open by the OpenClaw Foundation, a non-profit. See CONTRIBUTING.md for maintainers and contribution guidelines; AI-assisted PRs are welcome.
Use the issue chooser for bugs and feature requests, ask setup questions in Discord, and report vulnerabilities through SECURITY.md. New capabilities usually belong in plugins built on the plugin SDK and shared through ClawHub.
OpenClaw was built for Molty, a space lobster AI assistant, by Peter Steinberger and the community. Explore the project lore, soul.md, Peter's site, Star History, and @openclaw.
Special thanks to Mario Zechner for his support and for pi, and to Adam Doppelt for the lobster.bot domain.
