README.md

OpenClaude is an open-source coding-agent CLI for cloud and local model providers.

Use OpenAI-compatible APIs, Gemini, GitHub Models, Codex OAuth, Codex, Ollama, Atomic Chat, and other supported backends while keeping one terminal-first workflow: prompts, tools, agents, MCP, slash commands, and streaming output.

## Why OpenClaude

- One CLI across cloud APIs and local model backends — no per-provider tooling
- Guided provider setup and saved profiles with `/provider`
- Coding-agent workflows in one place: bash, file tools, grep, glob, agents, tasks, MCP, and web tools
- A bundled VS Code extension for launch integration and theme support
- A pixel-art hero companion who fires an arrow every time you press Enter (really — see [Meet your buddy](#meet-your-buddy))

## Quick Start

### Install

OpenClaude requires Node.js `>=22.0.0` for npm installs and runtime. Bun is
only needed for source builds and local development.

```bash
npm install -g @twigpine/openclaude@latest
```

**Upgrading from `@gitlawb/openclaude`?** The package moved to the `@twigpine`
scope and the old one is no longer updated. Both packages provide the
`openclaude` command, so npm refuses to install one over the other — remove
the old one first:

```bash
npm uninstall -g @gitlawb/openclaude
npm install -g @twigpine/openclaude@latest
```

Your settings and sessions (`~/.openclaude` and `~/.openclaude.json`) are not
touched. Don't use `--force` to install over the old package instead: a later
uninstall of the old one would then remove the `openclaude` command. If that
happens, uninstall `@twigpine/openclaude` and install it again.

If you're on Arch Linux, you can install OpenClaude from the community-maintained [AUR package](https://aur.archlinux.org/packages/openclaude):
```bash
paru -S openclaude
```

If the install later reports `ripgrep not found`, install ripgrep system-wide and confirm `rg --version` works in the same terminal before starting OpenClaude.

**Verify / troubleshoot installed version:**

```bash
openclaude --version
npm view @twigpine/openclaude dist-tags
npm install -g @twigpine/openclaude@latest
```

### Start

```bash
openclaude
```

Inside OpenClaude:

- run `/provider` for guided provider setup and saved profiles
- run `/onboard-github` for GitHub Models onboarding
- run `/search` to choose the web search backend (Exa by default) or add a search API key

> **Note:** OpenClaude does not automatically load project `.env` files. We recommend using the `/provider` command for setup, which saves provider profiles and credentials in `.openclaude-profile.json`. If you prefer environment variables, export them explicitly or run `openclaude --provider-env-file .env` for provider/setup variables. Export runtime/debug knobs from your shell or launcher.

### Resume or fork a conversation

Resume an existing conversation by session ID, or continue the most recent
conversation in the current directory:

```bash
openclaude --resume <session-id>
openclaude --continue
```

Add `--fork-session` to branch the conversation history into a new session ID
instead of reusing the original transcript:

```bash
openclaude --resume <session-id> --fork-session
openclaude --continue --fork-session
```

Forking is conversation branching only. It does not create filesystem isolation,
copy your working tree, or create a git worktree branch.

### Manage saved conversations

Run `/sessions` inside OpenClaude to list this project's saved conversations.
Press Enter on one to **Resume**, **Delete** (asks for confirmation, defaulting
to Cancel), or go **Back** to the list. As a shortcut, press `d` on a row and
then `d` again to delete it; any other key in between cancels. Deleting removes
the transcript and its sidecar files from disk and cannot be undone. The
session you are currently in is not listed and cannot be deleted.

### Background sessions

Run long non-interactive prompts detached from the current terminal:

```bash
openclaude --bg "fix failing tests"
openclaude --bg --name auth-refactor "refactor auth middleware"
openclaude ps
openclaude logs auth-refactor
openclaude logs auth-refactor -f
openclaude kill auth-refactor
```

Background sessions are local child processes. OpenClaude does not start a daemon
or network service, and permission/provider/model/settings flags are passed to
the child process the same way they are for a foreground `--print` run. Session
metadata and logs are stored under the resolved OpenClaude config directory,
usually `~/.openclaude/bg-sessions/`; `OPENCLAUDE_CONFIG_DIR` can point
OpenClaude somewhere else. `CLAUDE_CONFIG_DIR` is ignored for OpenClaude
background-session storage. Session names can be reused after older sessions
reach a terminal state; use the session ID to inspect older logs with the same
name. A naturally finished session is recorded as `exited` when its process
returns zero and `failed` when it returns nonzero or handles a termination
signal. `stale` remains the conservative result when the process disappears
without an observed outcome; an explicit successful `openclaude kill` is
recorded as `killed`, and `killed` takes precedence over a natural `exited` or
`failed` outcome for the same process. Terminal outcomes are stored separately
under `bg-sessions/terminal/`; deleting that directory makes finished sessions
fall back to liveness-derived status. OpenClaude does not infer POSIX signal
names on Windows.
Unobservable force termination, host crashes, and power loss remain `stale` on
every platform.

`openclaude attach <id-or-name>` currently reports the matching session and
points to `openclaude logs <id> -f`; full terminal reattach is not implemented
for local background sessions yet.

### OpenClaude config cutover

OpenClaude stores its own config under `~/.openclaude` and `~/.openclaude.json`
by default. It does not read `~/.claude`, project `.claude/` directories, or
`CLAUDE_CONFIG_DIR`; new users can start with an empty OpenClaude config and do
not need Claude Code installed.

If you previously used OpenClaude with `.claude` paths, migrate intentionally:
copy only the settings, commands, agents, skills, scheduled tasks, or other files
you personally created for OpenClaude into the matching `.openclaude` location.
Do not blanket-copy `.claude`, and do not copy Claude Code credentials or auth
files. For provider authentication, prefer running OpenClaude's provider setup
again or exporting provider-specific environment variables.

### Fastest OpenAI setup

macOS / Linux:

```bash
export CLAUDE_CODE_USE_OPENAI=1
export OPENAI_API_KEY=sk-your-key-here
export OPENAI_MODEL=gpt-4o

openclaude
```

Windows PowerShell:

```powershell
$env:CLAUDE_CODE_USE_OPENAI="1"
$env:OPENAI_API_KEY="sk-your-key-here"
$env:OPENAI_MODEL="gpt-4o"

openclaude
```

### Fastest local Ollama setup

macOS / Linux:

```bash
export CLAUDE_CODE_USE_OPENAI=1
export OPENAI_BASE_URL=http://localhost:11434/v1
export OPENAI_MODEL=qwen2.5-coder:7b

openclaude
```

Windows PowerShell:

```powershell
$env:CLAUDE_CODE_USE_OPENAI="1"
$env:OPENAI_BASE_URL="http://localhost:11434/v1"
$env:OPENAI_MODEL="qwen2.5-coder:7b"

openclaude
```

For Ollama, OpenClaude uses Ollama's native chat API and requests a 32768-token
context window on each chat request so same-session history is not silently
truncated by Ollama's OpenAI-compatible shim. Set `OPENCLAUDE_OLLAMA_NUM_CTX`
or `OLLAMA_CONTEXT_LENGTH` if you need a different request-level context size.
See [Advanced Setup](docs/advanced-setup.md#ollama-context-length) for
verification with `ollama ps`.

| NEAR AI | `/provider` or env vars | Unified gateway (Claude, GPT, Gemini + TEE open models); uses `NEARAI_API_KEY` at `https://cloud-api.near.ai/v1` |
| Cloudflare Workers AI | `/provider` or env vars | OpenAI-compatible API at `https://api.cloudflare.com/client/v4/accounts/<ACCOUNT_ID>/ai/v1`; uses `CLOUDFLARE_API_TOKEN`. Replace `<ACCOUNT_ID>` with your Cloudflare account id. |
| Ollama | `/provider` or env vars | Local inference with no API key |
| Atomic Chat | `/provider`, env vars, or `bun run dev:atomic-chat` | Local Model Provider; auto-detects loaded models |
| Bedrock / Vertex / Foundry | env vars | Anthropic-family cloud routes; Vertex is for Claude on Vertex AI, not arbitrary Model Garden models |

## What Works

- **Tool-driven coding workflows**: Bash, file read/write/edit, grep, glob, agents, tasks, MCP, and slash commands
- **Streaming responses**: Real-time token output and tool progress
- **Tool calling**: Multi-step tool loops with model calls, tool execution, and follow-up responses
- **Images**: URL and base64 image inputs for providers that support vision. Paste from the clipboard with Ctrl+V (Alt+V on Windows). 1080p/4K screenshots still attach. If processing fails and the image is over the 5MB payload limit or the 8000px API edge, the prompt shows that error instead of "No image found". For Anthropic requests containing more than 20 images (including retained conversation history and tool results), local images must fit within 2000×2000 pixels. On Amazon Bedrock and Google Cloud Vertex AI, document blocks also count toward that 20-block threshold. OpenClaude attempts to resize them before sending; if processing cannot produce a compliant image, it reports an actionable error rather than silently dropping attachments. Resize the affected images or start a new conversation with fewer images (or documents on those partners).
- **Provider profiles**: Guided setup plus saved user-level provider profile support
- **Local and remote model backends**: Cloud APIs, local servers, and Apple Silicon local inference
- **Codebase intelligence (repo map)**: Structural map of the repository ranked by PageRank importance, auto-injected into context when the `REPO_MAP` flag is enabled or the `REPO_MAP` environment variable is set. Inspect with `/repomap` (2048-token default). See [docs/repo-map.md](docs/repo-map.md) for details.
- **A companion with signature moves**: A truecolor pixel-art hero who lives beside your prompt and reacts when you work. See below.

## Meet Your Buddy

Run `/buddy` to hatch a companion — a truecolor pixel-art hero who stands
beside your prompt, idles, blinks, and fires their signature move every time
you submit a message:

```
/buddy                  hatch (first run) or pet your companion
/buddy set robinhood    the green archer — arrow shot on every Enter
/buddy set kaio         gold-haired warrior — charges a full-width energy wave
/buddy set strawhat     stretchy punch that snaps back
/buddy set merlin       twinkling sparkle stream
/buddy set kage         spinning shuriken
/buddy set ember        dragon fire with a real heat gradient
/buddy set corsair      cannonball with smoke trail
/buddy name Robin       rename your companion
/buddy set random       back to your rolled hero
```

Companions respect `prefersReducedMotion`, degrade gracefully to line art in
low-color terminals, and can be silenced with `/buddy mute`. Requires a
terminal at least 100 columns wide for the full sprite.

## Provider Notes

OpenClaude supports multiple providers, but behavior is not identical across all of them.

- Anthropic-specific features may not exist on other providers
- Tool quality depends heavily on the selected model
- Smaller local models can struggle with long multi-step tool flows
- Some providers impose lower output caps than the CLI defaults, and OpenClaude adapts where possible
- AI/ML API uses the OpenAI-compatible route, defaults to `gpt-4o`, and only surfaces chat-capable models from its public catalog
- Twigpine Opengateway is the fresh-install startup default and requires an API key from https://gitlawb.com/opengateway/keys. It uses one OpenAI-compatible base URL; switch between `mimo-*` and `google/gemini-3.1-flash-lite-preview` with `/model`, and do not pin the base URL to `/v1/xiaomi-mimo`.
- Z.AI GLM Coding Plan uses `https://api.z.ai/api/coding/paas/v4` with `glm-5.2` by default. On that direct route, GLM-5.3-Flash is selectable as `glm-5.3-flash` and accepts image input. Its OpenClaude effort choices are `low`, `high`, and `xhigh`, with `xhigh` requesting Z.AI `max`; GLM-5.3 and the existing GLM-5.2 query controls remain supported. These capabilities are not claimed for gateways that happen to carry the same model name.
- Xiaomi MiMo uses `api-key` header auth on the direct OpenAI-compatible route and currently does not support `/usage` reporting in OpenClaude
- GitHub Copilot serializes sub-agent execution by default to reduce Premium Request consumption — see [Agent Routing and Step Limits](docs/agent-routing.md#github-copilot-sub-agent-optimization) for tuning

For best results, use models with strong tool/function calling support.

## Agents

Route different agents to different models (cost optimization, splitting work
by model strength), cap sub-agent tool steps with `maxSteps`, and tune GitHub
Copilot sub-agent behavior. Configured via settings, agent frontmatter, and
environment variables:

- per-agent provider/model overrides via `agentModels` + `agentRouting` in `~/.openclaude/settings.json`
- model-only routes that reuse your current provider's credentials
- built-in agents (`Explore` and `Plan` [feature-gated], `verification` [feature-gated: requires `VERIFICATION_AGENT` + `tengu_hive_evidence`], `code-reviewer` [requires diff inline]) routable by type name

See [Agent Routing and Step Limits](docs/agent-routing.md) for the full guide.

## Web Search and Fetch

[Exa](https://exa.ai) is the default web search backend. With no setup, `WebSearch` on non-Anthropic models uses Exa's keyless free tier, which has per-second and daily limits. Run `/search` to pick a backend, add an API key, or test search:

```text
/search              # pick a backend
/search key exa      # add an Exa API key (hidden input) for higher limits
/search remove-key   # remove a saved Exa key
/search status       # show which backend handles searches
/search test         # run a test search
/search anysearch    # select AnySearch (works without a key)
/search key anysearch # optionally add an AnySearch API key in the hidden input
```

Other backends in the auto chain that you configure with a key (Tavily, Brave, Firecrawl, …) run before the Exa free tier, and DuckDuckGo is the last-resort fallback. When the active provider is Ollama, OpenClaude uses the signed-in local Ollama Web Search endpoint ahead of the free tier. Set `OLLAMA_API_KEY` to enable the hosted Ollama endpoint as a fallback. Set `EXA_FREE_TIER=0` if searches should never go to Exa without a key. See [Web Search Providers](src/tools/WebSearchTool/README_SEARCH_PROVIDERS.md) for every backend and option.

AnySearch is available as an explicit backend with `/search anysearch` or `WEB_SEARCH_PROVIDER=anysearch`. `ANYSEARCH_API_KEY` is optional; anonymous access has lower service limits. Set `ANYSEARCH_MAX_RESULTS` to an integer from 1 to 10 (default 10) to control the requested result count. AnySearch does not change the `auto` search order.

> **Note:** DuckDuckGo fallback works by scraping search results and may be rate-limited, blocked, or subject to DuckDuckGo's Terms of Service.

For Anthropic-native backends and Codex responses, OpenClaude keeps the native provider web search behavior unless you pick a specific backend with `/search` (for example `/search exa`).

To select Ollama search explicitly, use `WEB_SEARCH_PROVIDER=ollama`. A local Ollama route uses its configured `OPENAI_BASE_URL` or `OLLAMA_BASE_URL`; hosted search sends `OLLAMA_API_KEY` only to `https://ollama.com/api/web_search`.

`WebFetch` works, but its basic HTTP plus HTML-to-markdown path can still fail on JavaScript-rendered sites or sites that block plain HTTP requests.

Set a [Firecrawl](https://firecrawl.dev) API key if you want Firecrawl-powered search/fetch behavior:

```bash
export FIRECRAWL_API_KEY=your-key-here
```

With Firecrawl enabled:

- `WebSearch` can use Firecrawl's search API while the Exa free tier remains the default free path for non-Claude models
- `WebFetch` uses Firecrawl's scrape endpoint instead of raw HTTP, handling JS-rendered pages correctly

Free tier at [firecrawl.dev](https://firecrawl.dev) includes 500 credits. The key is optional.

## Headless gRPC Server

OpenClaude can run as a headless gRPC service with bidirectional streaming —
integrate its agentic capabilities into other applications, CI/CD pipelines,
or custom UIs. Start it with `npm run dev:grpc`; a test CLI client ships with
the repo. See [Headless gRPC Server](docs/grpc-server.md) for configuration
and client generation from `src/proto/openclaude.proto`.

## Development

Use Node.js `>=22.0.0` and Bun `1.3.13` or newer for source builds.

```bash
bun install
bun run build
node dist/cli.mjs
```

Day-to-day commands:

- `bun run dev` — build and launch from source
- `bun test` — full unit suite (Bun's built-in runner)
- `bun test path/to/file.test.ts` — focused runs for the areas you touch
- `bun run test:coverage` — coverage to `coverage/lcov.info` plus a visual report at `coverage/index.html` (`bun run test:coverage:ui` rebuilds just the UI)
- `bun run smoke` — smoke checks
- `bun run doctor:runtime`, `bun run verify:privacy`; for PR intent scanning, use the fresh-upstream, explicit-ref workflow in the [local pre-push validation contract](CONTRIBUTING.md#validation)

Focused suites: `bun run test:provider`, `bun run test:provider-recommendation`.

To benchmark the launcher module compile cache, build the CLI and run:

```bash
bun run build
bun run benchmark:startup
```

The benchmark requires Node `>=22.8.0`, where the compile-cache API was added;
the built OpenClaude launcher continues to support the declared Node `>=22.0.0`
runtime range.

The benchmark defaults to 30 separate-process warm runs and 10 isolated
empty-cache runs. It reports the median, IQR, MAD, first cache-populating run,
first warm-up, Node/OS/CPU details, bundle size, and commit. Direct bundle
timings are included only as a secondary diagnostic; the full launcher result
is the decision signal. Use
`bun run benchmark:startup -- --warm-runs 40 --cold-runs 10` to request a
larger sample set. The benchmark records results without enforcing a timing
threshold in CI.

OpenClaude leaves Node's standard compile-cache controls authoritative. Set
`NODE_DISABLE_COMPILE_CACHE=1` to disable the optimization, including for V8
coverage runs that require uncached compilation.

Before opening or updating a PR, run the authoritative [local pre-push validation contract](CONTRIBUTING.md#validation). The commands below are useful for narrow iteration, but they do not replace that required preflight:

- `bun run build`
- `bun run smoke`
- `bun run test:coverage` when your change affects shared runtime or provider logic
- focused `bun test ...` runs for the files and flows you changed
