- May 8, 2026 (v3.05.78): Research lab Phase A — autonomous multi-day research; WeChat smart-reply +
/draftsemi-auto reply; reliability + UX hardening across the lab pipeline. Two big surfaces shipped together: (a) the research lab is no longer single-shot —/lab resume <run_id> [<stage>]reconstructsLabStatefrom SQLite to continue or rewind a run;/lab iterate <run_id>runs a 3-reviewer self-review on the final report (novelty / rigor / clarity / evidence, 1-10), routes the lowest-scoring dimension to the corresponding stage (novelty→QUESTIONING, rigor→IMPLEMENTATION, clarity→DRAFTING, evidence→EXPERIMENT), rewinds + re-runs, loops untiltarget_score/max_iterations/ plateau / budget;/lab backlog add <topic> --iterate --target=N --max=N --prio=Nqueues many topics,/lab daemon startruns them 24/7 in a single-worker loop with crash-recovery (reset_running_backlogunsticks stale rows on next start);/lab modelsprints the effective per-role model + which API key drove each pick + warns when reviewers span <N families (homogeneous review = no meta-loop signal);/lab migrate-paths [--apply]renames legacylab_xxx/output dirs to the human-readable<date>_<time>_<topic-slug>_<run_id_short>form (e.g.2026-05-08_14-30_post-transformer-architectures-survey_b16036de/). (b) WeChat smart-reply panel — when a whitelisted contact sends an inbound message, an auxiliary cheap model drafts 3 candidate replies and pushes them as a panel to yourfilehelper(文件传输助手); reply with1/2/3/AA 1to send, freeform text to customise,xto skip,qfor queue. SQLite-persisted at~/.cheetahclaws/wx_smart_reply.db(in-memory fallback on init failure); contacts JSON at~/.cheetahclaws/wx_contacts.jsonis mtime-hot-reloaded; bot-owner self-uid is auto-recorded on first inbound and excluded from smart-reply unconditionally, so your own messages always reach the agent regardless of whitelist contents. (c)/draft <message>slash command — semi-automatic reply suggestion path for cases where the bot can't intercept the inbound directly (bot account ≠ user main account on iLink ClawBot). 3 candidates drafted via the auxiliary model, optionally tone-conditioned via@<contact_uid_or_label>againstwx_contacts.json; when invoked from a bridge channel (WeChat / Telegram / Slack), candidates are also echoed back to the originating uid + stashed inbridges.draft_cacheso a digit-only reply (1/2/3) consumes the chosen text one-shot, no agent invocation, no smart-reply panel triggered. Reliability hardening on top of #88's MCP work:research/http.pynow uses 429-aware backoff (10/30/60/120s vs 0.5/1/2/4s for 5xx) and honoursRetry-Afterheaders (capped at 180s); the lab surveyor stage grounds in realresearch.aggregator.research()hits before invoking the LLM (top-30 academic+tech results passed as context, persisted assurvey_search_hitsartifact for replay) — fabricated-citation rate drops sharply on tested topics;_dedupe_self_repeat()trims cheap-model degenerate sampling (text == text+text) before storage so reviewer prompts don't see doubled inputs;_extract_numbereddedupes by content (questioner emitting1..5\n1..5keeps 5, not 10); the citation verifier now has a per-citation 30sconcurrent.futureshard wall-clock (kills slow-loris sockets that urllib's socket-timeout ignores) + a 5-min stage-level cap with progress callbacks surfaced to/lab logs(the 11-min hang we saw in the field is gone). REPL ergonomics:/lab daemon startand/lab startnow print the eventual report.md path up front + live-stream stage transitions to the terminal as they happen;/lab status <run_id>shows both new + legacy paths so the user can find old reports too;/configparses JSON-style values (lists, dicts, signed numbers, quoted strings) —/config wechat_smart_reply_whitelist=["wxid_..."]no longer silently saved as a literal string; leading whitespace before/is now stripped before slash-dispatch (so a paste with a stray space still hits the dispatcher, not the agent). Tests: 884 passing (842 unit/integration + 22 e2e), zero regressions; ~80 new pytest cases covering iteration scoring, state reconstruction, backlog atomicity, verifier hard-timeout, slug edge cases, dedupe patterns, self-uid bypass.** - May 7, 2026 (v3.05.77): MCP HTTP/SSE transport + OAuth 2.0 PKCE,
.envloader,ANTHROPIC_ENDPOINTcorporate-proxy override, AskUserQuestion UI polish (#88, #89) —cc_mcp/client.pynow speaks Streamable HTTP (POST →text/event-streamreply) in addition to stdio and pure SSE, with theAccept: application/json, text/event-streamheader servers like sap-jira require to stop 406-ing. OAuth 2.0: newcc_mcp/oauth.pyimplements the full MCP Authorization spec — RFC 9728 resource-server discovery → RFC 8414 AS metadata → RFC 7591 dynamic client registration → Authorization Code + PKCE (S256) flow with browser redirect → automatic refresh-token rotation. Tokens persist atomically to~/.cheetahclaws/mcp_oauth.jsonat mode0600with the parent directory locked to0700. The redirect-URI port is picked once and reused for both registration and the local callback server, the OAuth scope is sourced from the AS's advertisedscopes_supported(preferringmcpif listed, otherwise the first one, otherwise omitted entirely so servers without anmcpscope no longer reject withinvalid_scope), and_ensure_oauth()is guarded by a dedicated lock so concurrent 401-retries can't race on the httpx client rebuild. REPL:/mcp add <name> --transport http <url>and/mcp add <name> --transport sse <url>for one-line HTTP server registration; explicit/mcp listsubcommand with full-width tool descriptions wrapped at 72 cols. Server name sanitization: hyphenated names likegithub-toolsnow resolve correctly through themcp__server__toolqualified-name path..envloader:_load_env()runs at the very top ofcheetahclaws.pybefore any other import readsos.environ, so.envkeys are visible to every module without losing existing-shell-var precedence (os.environ.setdefault). MCP HTTPheadersvalues are passed throughos.path.expandvars, so"Authorization": "Bearer $GITHUB_TOKEN"works out of the box.ANTHROPIC_ENDPOINTenv var (also reachable via.env) overrides the persistedanthropic_endpointconfig and is used by both the streaming Anthropic client (providers.pypassesbase_url=...toanthropic.Anthropic) and the connectivity probes in/doctor/ setup wizard, letting corporate proxies swapapi.anthropic.comcleanly. UI:AskUserQuestionis auto-approved alongsideEnterPlanMode/ExitPlanMode(it's an interactive tool by definition, a permission prompt was redundant), the spinner and result line are suppressed inprint_tool_start/end, the question text is rendered throughclr()with Markdown stripped (**bold**,`code`,*italic*), and option indices/descriptions are colorized. The REPL prompt now prints a full-width─rule viaos.get_terminal_size()(80-char fallback) before each input, matching Claude Code's visual rhythm.** - May 5, 2026: Telegram bridge file round-trip + cross-channel pickable permission prompts (#84) —
bridges/telegram.pypreviously only had_tg_send(text viasendMessage), so when the model claimed it had "sent a file" it was just text and the[approve][reject]text in permission prompts only looked like buttons. Added_tg_send_document(multipart/form-data upload, 49 MB cap with explicit oversize/empty/missing/network/API-rejection error reporting), an inbounddocumenthandler that saves uploads to/workspace(ortempfile.gettempdir()outside Docker) with sanitized filenames and a path-aware prompt, a!sendfile <path>user command for explicit on-demand sends, and an auto-send hook in_bg_runnerthat mails any file written by theWritetool — FIFO-paired with the in-flightfile_path, skipped onError:/Denied:results, and de-duplicated per turn so parallel writes don't double-mail. Cross-channel permission UX:ask_input_interactive(options=[(label, value), …])now renders an interactive picker on every bridge — Telegram gets a realinline_keyboard(callback_data="cc:<prompt_id>:<value>",_handle_callback_querydoes auth + stale-prompt-id drop +answerCallbackQuery+editMessageText "✓ Selected: y"), Slack and WeChat get a numbered menu in the message body (reply with digit / canonical letter / label word — all resolve via_resolve_choice), terminal prints the same numbered menu before the input cursor;ask_permission_interactivepasses[(✅ Approve, y), (❌ Reject, n), (✅✅ Accept all, a)]. Backward-compatible: every existingask_input_interactivecall site (nooptions=) keeps free-text behavior. 49 new pytest cases (tests/test_telegram_bridge.py+tests/test_options_menu.py) — no real network calls. 718 passed, zero regressions on the 669 pre-existing.--accept-allwas a red herring; the bridge simply lacked the upload code path. - May 3, 2026: Research Lab — autonomous multi-agent paper writing with sandboxed experiments + web UI. New
/lab start <topic>(CLI) and/labpage (web) drive 9 specialised agents — PI / Questioner / Surveyor / Designer / Engineer / Analyst / Writer / Reviewer × 3 / Lay Reader — through 9 stages: questioning → literature survey → outline → code drafting → sandboxed Python execution → analysis → paper drafting with reviewer iteration → citation verification (arXiv / Semantic Scholar / CrossRef) → finalisation. Reviewer pool defaults to 3 different provider families to reduce same-source rubber-stamping. Real experiments via subprocess sandbox with timeout /RLIMIT_CPU/RLIMIT_AS(v0 isolation; Docker is Phase 2.5). Output is a Markdown report with verified citations + BibTeX bundle + the engineer's runnable script and any plots. Targets arXiv-grade preprint quality, not top conferences — the LLM substrate caps quality, not orchestration. Single-run cost typically $2-15. Branch:feature/research-lab. Full guide:docs/guides/research-lab.md. - May 2, 2026: Daemon foundation lands (#80) —
cheetahclaws serve+cheetahclaws daemon {status, stop, logs, rotate-token}are real. F-1 of the 9-PR daemon roadmap merged via PR #80, on top of a re-landed spike (PR #81) that the RFC 0001 contract code lives in. End users see no new feature yet — F-1 ships the headless daemon + control surface, but no service runs inside it./healthz/readyz/metricsare now auth-gated by default per RFC 0001 §3 (opt out via--unauthenticated-metrics). Plus a polish follow-up (#82) closing four nits:daemonverbs honor--token-pathvia atoken_pathfield ondaemon.json;--helpdispatch returns 0; serve-mode prints flush immediately under&redirection. - May 2, 2026: Docker chat UI assets 404 follow-up (#73) —
web/server.pynow resolves_WEB_DIRviaimportlib.resources.files("web")instead ofPath(__file__).parent, so static files are found whether the package is installed editable or non-editable. The dotfile guard in the static-file branch now only inspects path segments inside_WEB_DIR, so installs sitting under.venv/,.local/, etc. no longer 404 every asset.[tool.setuptools.package-data]forwebwidened tostatic/**/*so non-editable wheels reliably ship the fullweb/static/subtree. Plus a newdocs/guides/docker.md"Custom Dockerfile pitfalls" section covering the editable-install requirement and the most common 404 root cause for users rolling their own image. - Apr 30, 2026: Docker / home-server support (#73) —
Dockerfile,docker-compose.yml,.env.example, host Ollama viahost.docker.internal, workspace bind-mount for Samba sharing.--webmode now auto-starts configured Telegram / WeChat / Slack bridges in the same process so a single container delivers browser UI + phone bridge. Plus two terminal/agent fixes:AskUserQuestionno longer deadlocks the terminal (#69) — synchronous render+read instead of a queue/event the agent thread can't drain.messages_to_openaiemitscontent: ""instead ofnullfor tool-only assistant turns so Ollama's OpenAI-compat endpoint stops 400-ing withinvalid message content type: <nil>; 400 /BadRequestErrorreclassified as a non-retryableINVALID_REQUESTso a malformed body no longer trips the circuit breaker (#71). - Apr 24, 2026: Support Deepseek V4 models, multi-model prompt adaptation — single shared
default.mdbaseline + tiny per-family overlays (Anthropic XML tags · Gemini 3 explicit Agentic Mode · OpenAI o-series no-narration). Routing is by model family, not provider/runtime — same Qwen prompt whether served via DashScope, Ollama, or OpenRouter. Overlays must cite a vendor prompting guide (≤ 20 lines, enforced by tests). DeepSeek v4 thinking-mode protocol (reasoning_contentround-trip +thinking: ONby default). fix(setup-wizard): tolerate api_key_env=None for ollama/lmstudio (#59) - Apr 20, 2026 (v3.05.76): Research pipeline — 20 sources across academia/tech/finance/social/web + cross-platform attention heat table, publication trend sparkline, notable-citer analysis, entity extraction, multi-query expansion, side-by-side compare, saved reports, weekly trend tracking via
/monitor, one-click/ssjwizard. Also including Chinese platforms: Zhihu (知乎) · Bilibili (B站) · Weibo (微博) · Rednote (小红书). - Apr 18, 2026 (v3.05.75): External plugin discovery via
CHEETAHCLAWS_PLUGIN_PATH+ safer dependency management; tool-history integrity fix for OpenAI-compatible providers (DeepSeek et al.); end-to-end prompt-cache token tracking across providers with full checkpoint round-trip - Apr 16, 2026 (v3.05.74): Web UI production hardening — persistence, multi-user auth, ops endpoints, JS module split, pytest suite

Why CheetahClaws
Claude Code is a powerful, production-grade AI coding assistant — but its source code is a compiled, 12 MB TypeScript/Node.js bundle (~1,300 files, ~283K lines). It is tightly coupled to the Anthropic API, hard to modify, and impossible to run against a local or alternative model.
CheetahClaws reimplements the same core loop in ~40K lines of readable Python, keeping everything you need and dropping what you don't. See here for more detailed analysis (CheetahClaws v3.03), English version and Chinese version

Where Claude Code wins
- UI quality — React/Ink component tree with streaming rendering, fine-grained diff visualization, and dialog systems.
- Tool breadth — 44 tools including
RemoteTrigger,EnterWorktree, and more UI-integrated tools. - Enterprise features — MDM-managed config, team permission sync, OAuth, keychain storage, GrowthBook feature flags.
- AI-driven memory extraction —
extractMemoriesservice proactively extracts knowledge from conversations without explicit tool calls. - Production reliability — single distributable
cli.js, comprehensive test coverage, version-locked releases.
Where CheetahClaws wins
- Multi-provider — switch between Claude, GPT-4o, Gemini 2.5 Pro, DeepSeek, Qwen, MiniMax, or a local Llama model with
--modelor/model— no recompile needed. - Local model support — run entirely offline with Ollama, LM Studio, or any vLLM-hosted model.
- Readable source — the full agent loop is 174 lines (
agent.py). Any Python developer can read, fork, and extend it in minutes. - Zero build —
pip install -r requirements.txtand you're running. Changes take effect immediately. - Dynamic extensibility — register new tools at runtime with
register_tool(ToolDef(...)), install skill packs from git URLs, or wire in any MCP server. - Task dependency graph —
TaskCreate/TaskUpdatesupportblocks/blocked_byedges for structured multi-step planning (not available in Claude Code). - Two-layer context compression — rule-based snip + AI summarization, configurable via
preserve_last_n_turns. - Notebook editing —
NotebookEditdirectly manipulates.ipynbJSON (replace/insert/delete cells) with no kernel required. - Diagnostics without LSP server —
GetDiagnosticschains pyright → mypy → flake8 → py_compile for Python and tsc/shellcheck for other languages, with zero configuration. - Offline voice input —
/voicerecords viasounddevice/arecord/SoX, transcribes with localfaster-whisper(no API key, no subscription), and auto-submits. Keyterms from your git branch and project files boost coding-term accuracy. - Cloud session sync —
/cloudsavebacks up conversations to private GitHub Gists with zero extra dependencies; restore any past session on any machine with/cloudsave load <id>. - SSJ Developer Mode —
/ssjopens a persistent power menu with 10 workflow shortcuts: Brainstorm → TODO → Worker pipeline, expert debate, code review, README generation, commit helper, and more. Stays open between actions; supports/commandpassthrough. - Telegram Bot Bridge —
/telegram <token> <chat_id>turns cheetahclaws into a Telegram bot: receive user messages, run the model, and send back responses — all from your phone. Slash commands pass through, and a typing indicator keeps the chat feeling live. - WeChat Bridge —
/wechat loginauthenticates with WeChat via a QR code scan (the same iLink Bot API used by the official WeixinClawBot /openclaw-weixinplugin), then starts a long-poll bridge. Slash command passthrough, interactive menu routing, typing indicator, session auto-recovery, and per-peercontext_tokenmanagement all work out of the box. - Slack Bridge —
/slack <xoxb-token> <channel_id>connects cheetahclaws to a Slack channel using the Slack Web API (stdlib only — noslack_sdkrequired). Pollsconversations.historyevery 2 seconds; replies update an in-place "Thinking…" placeholder. Slash command passthrough, interactive menu routing, and auto-start on launch. - Worker command —
/workerauto-implements pending tasks frombrainstorm_outputs/todo_list.txt, marks each one done after completion, and supports task selection by number (e.g.1,4,6). - Force quit — 3× Ctrl+C within 2 seconds triggers immediate
os._exit(1), unblocking any frozen I/O. - Proactive background monitoring —
/proactive 5mactivates a sentinel daemon that wakes the agent automatically after a period of inactivity, enabling continuous monitoring loops, scheduled checks, or trading bots without user prompts. - Rich Live streaming rendering — When
richis installed, responses stream as live-updating Markdown in place (no duplicate raw text), with clean tool-call interleaving. - Native Ollama reasoning — Local reasoning models (deepseek-r1, qwen3, gemma4) stream their
<think>tokens directly to the terminal viaThinkingChunkevents; enable with/verboseand/thinking. - Native Ollama vision —
/image [prompt]captures the clipboard and sends it to local vision models (llava, gemma4, llama3.2-vision) via Ollama's native image API. No cloud required. - Built-in Web UI —
--weblaunches a production-ready browser interface: multi-user accounts (bcrypt + JWT), SQLite-backed session history that survives restarts, rich Chat UI at/chatwith streaming messages, tool cards, permission approval, sidebar session CRUD + search + markdown export, light/dark/system theme, settings panel with per-provider API keys. Full xterm.js PTY terminal at/keeps 100% CLI parity. Ops endpoints (/health,/metrics) + structured JSON logs + 21 pytest end-to-end tests. Nine tiny vanilla-JS modules underweb/static/js/— no Node.js, no React, no build step.cheetahclaws --webauto-picks a free port if 8080 is taken. - Reliable multi-line paste — Bracketed Paste Mode (
ESC[?2004h) collects any pasted text — code blocks, multi-paragraph prompts, long diffs — as a single turn with zero latency and no blank-line artifacts. - Rich Tab completion — Tab after
/shows all commands with one-line descriptions and subcommand hints; subcommand Tab-complete works for/mcp,/plugin,/tasks,/cloudsave, and more. - Checkpoint & rewind —
/checkpointlists all auto-snapshots of conversation + file state;/checkpoint <id>rewinds both files and history to any earlier point in the session. - Plan mode —
/plan <desc>(or theEnterPlanModetool) puts Claude into a structured read-only analysis phase; only the plan file is writable. Claude writes a detailed plan, then/plan donerestores full write permissions for implementation.
CheetahClaws vs OpenClaw
OpenClaw is another popular open-source AI assistant built on TypeScript/Node.js. The two projects have different primary goals — here is how they compare.

| Hackability | Large codebase (245K lines), harder to modify | ~12K lines — full agent loop visible in one file |
Where OpenClaw wins
- Omni-channel inbox — connects to 20+ messaging platforms (WhatsApp, Signal, iMessage, Discord, Teams, Matrix, WeChat…); users interact from wherever they already are.
- Always-on daemon — Gateway runs as a background service (launchd/systemd); no terminal required for day-to-day use.
- Mobile-first — macOS menu bar, iOS Voice Wake / Talk Mode, Android camera/screen recording — feels like a native app, not a CLI tool.
- Live Canvas — agent-driven visual workspace rendered in the browser; supports A2UI push/eval/snapshot.
- Browser automation — dedicated Chrome/Chromium profile with snapshot, actions, and upload tools.
- Production reliability — versioned npm releases, comprehensive CI, onboarding wizard,
openclaw doctordiagnostics.
Where CheetahClaws wins
- Coding toolset — Read/Write/Edit/Bash/Glob/Grep/NotebookEdit/GetDiagnostics are purpose-built for software development; CheetahClaws understands diffs, file trees, and code structure.
- True local model support — full Ollama/vLLM/LM Studio integration with streaming, tool-calling, and vision — no cloud required.
- 8+ model providers — switch between Claude, GPT-4o, Gemini, DeepSeek, Qwen, MiniMax, and local models with a single
--modelflag. - Hackable in minutes — 12K lines of readable Python; the entire agent loop is in
agent.py; extend withregister_tool()at runtime without rebuilding. - Zero setup —
pip install cheetahclawsand runcheetahclaws; no daemon, no pairing, no onboarding wizard. - MCP support — connect any MCP server (stdio/SSE/HTTP); tools auto-registered.
- SSJ Developer Mode —
/ssjpower menu chains Brainstorm → TODO → Worker → Debate in a persistent interactive session; automates entire dev workflows. - Offline voice —
/voicetranscribes locally withfaster-whisper; no subscription, no OAuth, works without internet. - Session cloud sync —
/cloudsavebacks up full conversations to private GitHub Gists with zero extra dependencies.
When to choose which
| If you want… | Use |
|---|---|
| A personal assistant you can message on WhatsApp/Signal/Discord | OpenClaw |
| An AI coding assistant in your terminal | CheetahClaws |
| Full offline / local model support | CheetahClaws |
| A mobile-friendly always-on experience | OpenClaw |
| To read and modify the source in an afternoon | CheetahClaws |
| Browser automation and a visual Canvas | OpenClaw |
| Multi-provider LLM switching without rebuilding | CheetahClaws |
Key design differences
Agent loop — CheetahClaws uses a Python generator that yields typed events (TextChunk, ToolStart, ToolEnd, TurnDone). The entire loop is visible in one file, making it easy to add hooks, custom renderers, or logging.
Tool registration — every tool is a ToolDef(name, schema, func, read_only, concurrent_safe) dataclass. Any module can call register_tool() at import time; MCP servers, plugins, and skills all use the same mechanism.
Context compression
| Claude Code | CheetahClaws | |
|---|---|---|
| Trigger | Exact token count | len / 3.5 estimate, fires at 70 % |
| Layer 1 | — | Snip: truncate old tool outputs (no API cost) |
| Layer 2 | AI summarization | AI summarization of older turns |
| Control | System-managed | preserve_last_n_turns parameter |
Memory — Claude Code's extractMemories service has the model proactively surface facts. CheetahClaws's memory/ package is tool-driven: the model calls MemorySave explicitly, which is more predictable and auditable. Each memory now carries confidence, source, last_used_at, and conflict_group metadata; search re-ranks by confidence × recency; and /memory consolidate offers a manual consolidation pass without silently modifying memories in the background.
Who should use CheetahClaws
- Developers who want to use a local or non-Anthropic model as their coding assistant.
- Researchers studying how agentic coding assistants work — the entire system fits in one screen.
- Teams who need a hackable baseline to add proprietary tools, custom permission policies, or specialised agent types.
- Anyone who wants Claude Code-style productivity without a Node.js build chain.

| Voice input | Record → transcribe → auto-submit. Backends: sounddevice / arecord / SoX + faster-whisper / openai-whisper / OpenAI API. Works fully offline. |
| Brainstorm | /brainstorm [topic] generates N expert personas suited to the topic (2–100, default 5, chosen interactively), runs an iterative debate, saves results to brainstorm_outputs/, and synthesizes a Master Plan + auto-generates brainstorm_outputs/todo_list.txt. |
| SSJ Developer Mode | /ssj opens a persistent interactive power menu with 15 shortcuts: Brainstorm, TODO viewer, Worker, Expert Debate, Propose, Review, Readme, Commit, Scan, Promote, Video factory, TTS factory, Monitor, Trading, Agent. Stays open between actions; /command passthrough supported. |
| Trading agent v3.1 | Automatic candidate discovery: /trading discover all scans an S&P 100 universe and surfaces tickers from four orthogonal sources — SEC EDGAR Form 4 insider clusters, recent ≥10% earnings beats with post-print drift, momentum-quality factor intersection, leading sector ETFs' top holdings — then merges with a cross-source confluence bonus. /trading rank composite-ranks candidates by factor + discovery + calibration tilt. /trading anomaly flags unusual volume / price gaps / vol regime spikes. /trading monitor scan --notify telegram slack wechat runs anomaly + stop-loss + earnings + new-insider-filing detection and dispatches alerts to bridges. Single-name analysis: /trading analyze <SYMBOL> runs a multi-agent pipeline (Bull/Bear → Judge → Risk Panel → PM) with macro / earnings / insider / sentiment / trends / book context auto-injected. /trading review runs incremental HOLD/ADD/TRIM/EXIT debate on existing positions. Autonomous mode: /trading manage start hundred 100 creates a virtual $100 portfolio that the agent allocates + rebalances via mean-variance optimization (step / report). Persistent paper-trade tracker → /trading calibration answers "is the agent any good?" with hit-rate by confidence + t-stat vs zero. Hard risk verifier enforces position / sector / stop / earnings-blackout caps. /trading walkforward does honest OOS rolling-chunk backtesting. /trading ml train builds a LightGBM stacker. Broker abstraction: PaperBroker works out of the box, IBKRBroker stub for pip install ib_insync + IB Gateway. Supports US/HK/A-share stocks and 20+ cryptos. |
| Monitor | /monitor (no args → wizard) subscribes to AI-monitored topics on a schedule and pushes reports to Telegram/Slack/console. Topics: ai_research (arxiv), stock_<TICKER>, crypto_<SYMBOL>, world_news (Reuters/BBC/AP), custom:<query>. Schedules: 15m to weekly. Background scheduler daemon with /monitor start/stop/status. |
| Research (multi-source) | /research <topic> fans out to 20 sources in parallel and synthesizes a brief with inline citations, a cross-platform attention heat table, top-mentioned entities (models / benchmarks / orgs / people), and a 12-month publication trend sparkline: arXiv · Semantic Scholar · OpenAlex · HuggingFace Papers · alphaXiv · Google Scholar · HackerNews · GitHub · Reddit · StackOverflow · Google News · Polymarket · SEC EDGAR · Tavily · Brave · Twitter/X · 知乎 Zhihu · B站 Bilibili · 微博 Weibo · 小红书 Xiaohongshu. Supports --range 30d|6m|1y|… / --since YYYY-MM-DD / --until YYYY-MM-DD — each source translates to its native date filter. --citations surfaces "Notable citing authors" with ≥10k total citations. --expand asks the model for 2-6 sibling subqueries and merges their results for broader coverage. /research compare "A" vs "B" [vs "C"] produces a side-by-side comparative brief with [A-N]/[B-N]/[C-N]-prefixed citations. Every run auto-saves to ~/.cheetahclaws/research_reports/; /reports list|open|delete|path to browse, --save-as PATH to export. Weekly trend tracking: /subscribe research:<topic> weekly (or /ssj → 17. Trend Track) re-runs the whole pipeline automatically and pushes digests to Telegram / Slack / console. One-click wizard via /ssj → 16. Research / 17. Trend Track / 18. Reports. 13/20 sources zero-config; 7 optional (Tavily · Brave · Twitter · Zhihu · Weibo · Xiaohongshu · Google Scholar). See docs/guides/research.md. |
| Autonomous Agents | /agent (no args → wizard) launches autonomous background agent loops driven by Markdown task templates. 4 built-in templates: research_assistant, auto_bug_fixer, paper_writer, auto_coder. Iteration summaries pushed via bridge. Custom templates: drop a .md file into ~/.cheetahclaws/agent_templates/. |
| Remote Control job queue | All three bridges (Telegram/Slack/WeChat) maintain a per-bridge FIFO job queue when the AI is busy. !jobs / !j — dashboard; !job <id> — detail; !retry <id> — re-run a failed job; !cancel [id] — stop current job. Tool step tracking with on_tool_start/on_tool_end hooks. Persistent log at ~/.cheetahclaws/jobs.json. |
| Worker | /worker [task#s] reads brainstorm_outputs/todo_list.txt, implements each pending task with a dedicated model prompt, and marks it done (- [x]). Supports task selection (/worker 1,4,6), custom path (--path), and worker count limit (--workers). Detects and redirects accidental brainstorm .md paths. |
| Telegram bridge | /telegram <token> <chat_id> starts a bot bridge: receive messages from Telegram, run the model, and reply — all from your phone. Typing indicator, slash command passthrough (including interactive menus), and auto-start on launch if configured. |
| WeChat bridge | /wechat login authenticates via QR code scan (same as WeixinClawBot / openclaw-weixin plugin), then starts the iLink long-poll bridge. context_token echoed per peer, typing indicator, slash command passthrough, session expiry auto-recovery. Credentials saved for auto-start on next launch. |
| Slack bridge | /slack <xoxb-token> <channel_id> connects to a Slack channel via the Web API (no external packages). Polls conversations.history every 2 s; replies update an in-place "Thinking…" placeholder. Slash command passthrough, interactive menu routing, auth validation on start, auto-start on next launch. |
| Video factory | /video [topic] runs the full AI video pipeline: story generation (active model) → TTS narration (Edge/Gemini/ElevenLabs) → AI images (Gemini Web free or placeholders) → subtitle burn (Whisper) → FFmpeg assembly → final .mp4. 10 viral content niches, landscape or short format, zero-cost path available. |
| TTS factory | /tts interactive wizard: AI writes script (or paste your own) → synthesize to MP3 in any voice style (narrator, newsreader, storyteller, ASMR, motivational, documentary, children, podcast, meditation, custom). Engine auto-selects: Gemini TTS → ElevenLabs → Edge TTS (always-free). CJK text auto-switches to a matching voice. |
| Vision input | /image (or /img) captures the clipboard image and sends it to any vision-capable model — Ollama (llava, gemma4, llama3.2-vision) via native format, or cloud models (GPT-4o, Gemini 2.0 Flash, …) via OpenAI image_url multipart format. Requires pip install cheetahclaws[vision]; Linux also needs xclip. |
| Tmux integration | 11 tmux tools for direct terminal control: create sessions/windows/panes, send commands, capture output. Auto-detected; zero impact if tmux is absent. Enables long-running tasks that outlive Bash tool timeouts. Cross-platform (tmux on Unix, psmux on Windows). |
| Shell escape | Type !command in the REPL to execute any shell command directly without AI involvement (!git status, !ls, !python --version). Output prints inline. |
| Proactive monitoring | /proactive [duration] starts a background sentinel daemon; agent wakes automatically after inactivity, enabling continuous monitoring loops without user prompts |
| Force quit | 3× Ctrl+C within 2 seconds triggers os._exit(1) — kills the process immediately regardless of blocking I/O |
| Rich Live streaming | When rich is installed, responses render as live-updating Markdown in place. Auto-disabled in SSH sessions to prevent repeated output; override with /config rich_live=false. |
| Context injection | Auto-loads CLAUDE.md, git status, cwd, persistent memory |
| Session persistence | Autosave on exit to daily/YYYY-MM-DD/ (per-day limit) + history.json (master, all sessions) + session_latest.json (/resume); sessions include session_id and saved_at metadata; /load grouped by date |
| Cloud sync | /cloudsave syncs sessions to private GitHub Gists; auto-sync on exit; load from cloud by Gist ID. No new dependencies (stdlib urllib). |
| Extended Thinking | Toggle on/off for Claude models; native <think> block streaming for local Ollama reasoning models (deepseek-r1, qwen3, gemma4) |
| Cost tracking | Token usage + estimated USD cost |
| Non-interactive mode | --print flag for scripting / CI |
| Web UI | --web opens the browser. Multi-user accounts (bcrypt + JWT), SQLite-persisted history, session CRUD + markdown export, light/dark/system theme, /health + /metrics, auto-picks a free port if 8080 is busy. pip install 'cheetahclaws[web]'. |

Note: Tool calling requires a model that supports function calling. Recommended local models:
qwen2.5-coder,llama3.3,mistral,phi4.
OpenAI newer models (gpt-5 / o3 / o4 family): These models require
max_completion_tokensinstead of the legacymax_tokensparameter. CheetahClaws handles this automatically — no configuration needed.
Reasoning models:
deepseek-r1,qwen3, andgemma4stream native<think>blocks. Enable with/verboseand/thinkingto see thoughts in the terminal. Note: models fed a large system prompt (like cheetahclaws's 25 tool schemas) may suppress their thinking phase to avoid breaking the expected JSON format — this is model behavior, not a bug.
Installation
Quick Install (one command)
curl -fsSL https://raw.githubusercontent.com/SafeRL-Lab/cheetahclaws/main/scripts/install.sh | bash
Or
pip install cheetahclaws
Works on Linux, macOS, WSL2, and Android (Termux). The installer handles everything: checks Python 3.10+, clones the repo, installs via pip, and adds cheetahclaws to your PATH.
After installation:
source ~/.zshrc # macOS (zsh)
# or: source ~/.bashrc # Linux (bash)
cheetahclaws # start chatting!
First run will guide you through setup (pick provider, set API key). Or run cheetahclaws --setup anytime.
Windows: Native Windows is not supported. Install WSL2 and run the command above inside WSL.
Android / Termux: The installer auto-detects Termux and skips incompatible optional dependencies. Manual install:
pkg install python git && pip install cheetahclaws.
Alternative: install with pip
git clone https://github.com/SafeRL-Lab/cheetahclaws.git
cd cheetahclaws
pip install .
After that, cheetahclaws is available as a global command:
cheetahclaws # start REPL
cheetahclaws --model gpt-4o # choose a model
cheetahclaws -p "explain this" # non-interactive
cheetahclaws --setup # re-run setup wizard
To update after pulling new code:
cd cheetahclaws
git pull
pip install --force-reinstall .
Upgrading from a pre-2026-05-08 install? If you see
ModuleNotFoundError: No module named 'prompts'(ormodular.trading.discover, etc.) at startup, your existing wheel is from before the issue #97 packaging fix and is missing several sub-packages.pip install --force-reinstall .rebuilds and ships them all — see #97 for the root-cause writeup.
Optional extras
pip install ".[voice]" # voice input (sounddevice)
pip install ".[vision]" # clipboard image capture (Pillow)
pip install ".[autosuggest]" # typing-time slash command autosuggest (prompt_toolkit)
pip install ".[browser]" # headless browser for JS-rendered pages (playwright)
pip install ".[files]" # PDF + Excel reading (pymupdf, openpyxl)
pip install ".[ocr]" # image OCR (pytesseract, Pillow)
pip install ".[trading]" # trading agent (yfinance, rank-bm25)
pip install ".[all]" # everything above
Note: After installing
[browser], runplaywright install chromiumto download the browser binary.
Alternative: install with uv
uv installs cheetahclaws into an isolated environment and puts it on your PATH:
# Install uv (if not already installed)
curl -LsSf https://astral.sh/uv/install.sh | sh
# Clone and install with all optional dependencies (voice, vision, autosuggest, browser, files, OCR, trading etc.)
git clone https://github.com/SafeRL-Lab/cheetahclaws.git
cd cheetahclaws
uv tool install ".[all]"
Prefer a minimal install? Use uv tool install . (core only) and add extras later, e.g. uv tool install ".[voice,vision,autosuggest]" --reinstall.
To update: uv tool install ".[all]" --reinstall
To uninstall: uv tool uninstall cheetahclaws
Alternative: run directly from source (no install)
git clone https://github.com/SafeRL-Lab/cheetahclaws.git
cd cheetahclaws

Usage: Open-Source Models (Local)
Option A — Ollama (Recommended)
Ollama runs models locally with zero configuration. No API key required.
Step 1: Install Ollama
# macOS / Linux
curl -fsSL https://ollama.com/install.sh | sh
# Or download from https://ollama.com/download
Step 2: Pull a model
# Best for coding (recommended)
ollama pull qwen2.5-coder # 4.7 GB (7B)
ollama pull qwen2.5-coder:32b # 19 GB (32B)
# General purpose
ollama pull llama3.3 # 42 GB (70B)
ollama pull llama3.2 # 2.0 GB (3B)
# Reasoning
ollama pull deepseek-r1 # 4.7 GB (7B)
ollama pull deepseek-r1:32b # 19 GB (32B)
# Other
ollama pull phi4 # 9.1 GB (14B)
ollama pull mistral # 4.1 GB (7B)
Step 3: Start Ollama server (runs automatically on macOS; on Linux run manually)
ollama serve # starts on http://localhost:11434
Step 4: Run cheetahclaws
cheetahclaws --model ollama/qwen2.5-coder
cheetahclaws --model ollama/llama3.3
cheetahclaws --model ollama/deepseek-r1
Or
python cheetahclaws.py --model ollama/qwen2.5-coder
python cheetahclaws.py --model ollama/llama3.3
python cheetahclaws.py --model ollama/deepseek-r1
python cheetahclaws.py --model ollama/qwen3.5:35b
List your locally available models:
ollama list
Then use any model from the list:
cheetahclaws --model ollama/<model-name>
Option B — LM Studio
LM Studio provides a GUI to download and run models, with a built-in OpenAI-compatible server.
Step 1: Download LM Studio and install it.
Step 2: Search and download a model inside LM Studio (GGUF format).
Step 3: Go to Local Server tab → click Start Server (default port: 1234).
Step 4:
cheetahclaws --model lmstudio/<model-name>
# e.g.:
cheetahclaws --model lmstudio/phi-4-GGUF
cheetahclaws --model lmstudio/qwen2.5-coder-7b
The model name should match what LM Studio shows in the server status bar.
Option C — vLLM / Self-Hosted OpenAI-Compatible Server
For self-hosted inference servers (vLLM, TGI, llama.cpp server, etc.) that expose an OpenAI-compatible API:
Quick Start for option C: Step 1: Start vllm:
CUDA_VISIBLE_DEVICES=7 python -m vllm.entrypoints.openai.api_server \
--model Qwen/Qwen2.5-Coder-7B-Instruct \
--host 0.0.0.0 \
--port 8000 \
--enable-auto-tool-choice \
--tool-call-parser hermes
Step 2: Start cheetahclaws:
export CUSTOM_BASE_URL=http://localhost:8000/v1
export CUSTOM_API_KEY=none
cheetahclaws --model custom/Qwen/Qwen2.5-Coder-7B-Instruct
# Example: vLLM serving Qwen2.5-Coder-32B
python -m vllm.entrypoints.openai.api_server \
--model Qwen/Qwen2.5-Coder-32B-Instruct \
--port 8000 \
--enable-auto-tool-choice \
--tool-call-parser hermes
# Then run cheetahclaws pointing to your server:
cheetahclaws
Inside the REPL:
/config custom_base_url=http://localhost:8000/v1
/config custom_api_key=token-abc123 # skip if no auth
/model custom/Qwen2.5-Coder-32B-Instruct
Or set via environment:
export CUSTOM_BASE_URL=http://localhost:8000/v1
export CUSTOM_API_KEY=token-abc123
cheetahclaws --model custom/Qwen2.5-Coder-32B-Instruct
For a remote GPU server:
/config custom_base_url=http://192.168.1.100:8000/v1
/model custom/your-model-name
Model Name Format
Three equivalent formats are supported:
# 1. Auto-detect by prefix (works for well-known models)
cheetahclaws --model gpt-4o
cheetahclaws --model gemini-2.0-flash
cheetahclaws --model deepseek-chat
# 2. Explicit provider prefix with slash
cheetahclaws --model ollama/qwen2.5-coder
cheetahclaws --model kimi/moonshot-v1-128k
# 3. Explicit provider prefix with colon (also works)
cheetahclaws --model kimi:moonshot-v1-32k
cheetahclaws --model qwen:qwen-max
Auto-detection rules:
| Model prefix | Detected provider |

Trading Agent
CheetahClaws includes a built-in AI-powered trading analysis and backtesting module. Install trading dependencies:
pip install "cheetahclaws[trading]"
Multi-agent analysis
/trading analyze NVDA
Runs a 5-phase pipeline: data collection (technical indicators, fundamentals, news) → Bull/Bear researcher debate → research judge recommendation → risk management panel (aggressive / conservative / neutral) → portfolio manager final decision with a 5-tier rating: BUY / OVERWEIGHT / HOLD / UNDERWEIGHT / SELL.
Each agent uses BM25 memory to recall similar past situations and learns from outcomes via post-trade reflection.
Backtesting
/trading backtest AAPL dual_ma # single strategy
/trading backtest TSLA # AI picks best strategy
4 built-in strategies: dual_ma (SMA crossover), rsi_mean_reversion, bollinger_breakout, macd_crossover. Engines for US/HK equities and crypto. Reports Sharpe, Sortino, Calmar, max drawdown, win rate, profit factor.
SSJ integration
/ssj → 14. 📈 Trading opens a guided sub-menu:
| Option | Action |
|---|---|
| a. Quick Analyze | Full multi-agent analysis for any symbol |
| b. Backtest | Pick strategy or compare all 4 |
| c. Price Check | Current price + key metrics |
| d. Indicators | 11 technical indicators report |
| e. Trading Bot | Autonomous multi-symbol analysis |
| f. History | Past trading decisions |
| g. Memory | Trading memory status |
Supported markets
US stocks (AAPL), HK stocks (0700.HK), A-shares (000001.SZ), crypto (BTC, ETH, + 18 more). Data sources with automatic fallback chains — no API keys required.
Full guide: docs/guides/trading.md
Web UI
A production-ready browser interface with real user accounts, SQLite-backed session history, and ops endpoints — bundled Python stdlib HTTP server plus nine small vanilla-JS modules, no Node.js / React / build step.
Install and start
pip install 'cheetahclaws[web]' # pulls sqlalchemy + bcrypt + PyJWT
cheetahclaws --web # auto-picks a free port (tries 8080 first)
cheetahclaws --web --port 9000 # bind exactly :9000 (fails loudly if taken)
cheetahclaws --web --host 0.0.0.0 # open to the local network
cheetahclaws --web --no-auth # skip login (localhost dev only)
On first visit to http://localhost:<port>/chat, the UI routes you to a registration form — the first account becomes admin. Subsequent visits show Sign in. Credentials: bcrypt-hashed password + 7-day JWT cookie (ccjwt, HttpOnly, SameSite=Strict). The JWT signing key is persisted to ~/.cheetahclaws/web_secret so logins survive restarts.
Chat UI (/chat)
| Feature | Details |
|---|---|
| Streaming chat | WebSocket for live prompts + SSE for long-running slash commands |
| Persistent history | Every session + message lives in SQLite (~/.cheetahclaws/web.db). Server restart does not lose state. |
| Sidebar session management | Title auto-titled from first user message, relative time ("12m ago"), message count, busy dot, client-side search, right-click menu (Rename / Export Markdown / Delete) |
| Cross-user isolation | Each user only sees their own sessions — enforced at DB query and in-memory cache |
| Tool cards | Collapsible cards show tool name, inputs, outputs, status (running / done / denied) |
| Permission approval | Inline Allow / Deny buttons |

PTY Terminal (/)
Full xterm.js terminal — still there, still 100% CLI parity. Uses the same one-time generated password (printed on startup) — separate from the chat JWT flow.

Docker / Home Server
For headless deployments (home server with local Ollama, cloud VM, container host) the repo ships a Dockerfile and docker-compose.yml. The web UI plus any configured Telegram / WeChat / Slack bridge run together in a single container:
cp .env.example .env # set UID/GID and any cloud API keys
mkdir -p workspace data
docker compose up -d --build
# open http://<host-ip>:8080/chat
The container reaches an Ollama instance running on the host via host.docker.internal:11434. Mount ./workspace into the container and share it over Samba to access the agent's working files from your phone or other PCs.

FAQ
Q: How do I add an MCP server?
Option 1 — via REPL (stdio server):
/mcp add git uvx mcp-server-git
Option 2 — create .mcp.json in your project:
{
"mcpServers": {
"git": {"type": "stdio", "command": "uvx", "args": ["mcp-server-git"]}
}
}
Then run /mcp reload or restart. Use /mcp to check connection status.
Q: An MCP server is showing an error. How do I debug it?
/mcp # shows error message per server
/mcp reload git # try reconnecting
If the server uses stdio, make sure the command is in your $PATH:
which uvx # should print a path
uvx mcp-server-git # run manually to see errors
Q: Can I use MCP servers that require authentication?
For HTTP/SSE servers with a Bearer token:
{
"mcpServers": {
"my-api": {
"type": "sse",
"url": "https://myserver.example.com/sse",
"headers": {"Authorization": "Bearer sk-my-token"}
}
}
}
For stdio servers with env-based auth:
{
"mcpServers": {
"brave": {
"type": "stdio",
"command": "uvx",
"args": ["mcp-server-brave-search"],
"env": {"BRAVE_API_KEY": "your-key"}
}
}
}
Q: Tool calls don't work with my local Ollama model.
Not all models support function calling. Use one of the recommended tool-calling models: qwen2.5-coder, llama3.3, mistral, or phi4.
ollama pull qwen2.5-coder
cheetahclaws --model ollama/qwen2.5-coder
Q: How do I connect to a remote GPU server running vLLM?
/config custom_base_url=http://your-server-ip:8000/v1
/config custom_api_key=your-token
/model custom/your-model-name
Q: How do I check my API cost?
/cost
Input tokens: 3,421
Output tokens: 892
Est. cost: $0.0648 USD
Q: Can I use multiple API keys in the same session?
Yes. Set all the keys you need upfront (via env vars or /config). Then switch models freely — each call uses the key for the active provider.
Q: How do I make a model available across all projects?
Add keys to ~/.bashrc or ~/.zshrc. Set the default model in ~/.cheetahclaws/config.json:
{ "model": "claude-sonnet-4-6" }
Q: Qwen / Zhipu returns garbled text.
Ensure your DASHSCOPE_API_KEY / ZHIPU_API_KEY is correct and the account has sufficient quota. Both providers use UTF-8 and handle Chinese well.
Q: Can I pipe input to cheetahclaws?
echo "Explain this file" | cheetahclaws --print --accept-all
cat error.log | cheetahclaws -p "What is causing this error?"
Q: How do I run it as a CLI tool from anywhere?
Use uv tool install — it creates an isolated environment and puts cheetahclaws on your PATH:
cd cheetahclaws
uv tool install ".[all]"
After that, just run cheetahclaws from any directory. To update after pulling changes, run uv tool install ".[all]" --reinstall. For a minimal install, use uv tool install . and add extras as needed.
Q: How do I set up voice input?
# Minimal setup (local, offline, no API key):
pip install sounddevice faster-whisper numpy
# Then in the REPL:
/voice status # verify backends are detected
/voice # speak your prompt
On first use, faster-whisper downloads the base model (~150 MB) automatically.
Use a larger model for better accuracy: export NANO_CLAUDE_WHISPER_MODEL=small
Q: Voice input transcribes my words wrong (misses coding terms).
The keyterm booster already injects coding vocabulary from your git branch and project files.
For persistent domain terms, put them in a .cheetahclaws/voice_keyterms.txt file (one term per line) — this is checked automatically on each recording.
Q: Can I use voice input in Chinese / Japanese / other languages?
Yes. Set the language before recording:
/voice lang zh # Mandarin Chinese
/voice lang ja # Japanese
/voice lang auto # reset to auto-detect (default)
Whisper supports 99 languages. auto detection works well but explicit codes improve accuracy for short utterances.
