@weave-os/router

One command, anywhere, to point Claude Code, Codex, opencode, or pi at the Weave Router.

The package was renamed from @workweave/router. The old package remains published as a compatibility alias and continues to receive the same releases; it prints a migration warning directing users to @weave-os/router.

npx @weave-os/router                       # interactive: pick Claude Code / Codex / opencode / pi, then scope
npx @weave-os/router --claude              # skip the picker, target Claude Code
npx @weave-os/router --codex               # skip the picker, target the OpenAI Codex CLI
npx @weave-os/router setup --claude --codex # configure both native clients
npx @weave-os/router accounts list --claude # list enrolled subscription accounts
npx @weave-os/router login claude           # enroll Claude Pro/Max with PKCE
npx @weave-os/router login codex            # enroll ChatGPT Pro/Plus device flow
npx @weave-os/router status                 # connectivity, native configs, account health
npx @weave-os/router --opencode            # skip the picker, target opencode
npx @weave-os/router --pi                  # skip the picker, target pi + Loom UI
npx @weave-os/router --scope project       # per-repo install, commit settings.json (or .codex/ / opencode.json)
npx @weave-os/router --local               # self-hosted via docker-compose (localhost:8080)
npx @weave-os/router --base-url https://router.acme.internal
npx @weave-os/router --non-interactive     # reads $WEAVE_ROUTER_KEY, no prompts (defaults to claude)

Re-running the installer to pick up changes reuses the key already on disk, so you paste it once and never again — for every client, not just Claude Code. update is the never-prompting form of that (safe for cron; errors instead of asking when no key can be found):

npx @weave-os/router --claude                # reuses the installed key
npx @weave-os/router --codex                 # same for Codex, opencode, and pi
npx @weave-os/router --claude --rotate-key   # ignore it and prompt for a new one
npx @weave-os/router update --claude         # non-interactive refresh in place

For Claude Code the installed statusline and /force-model, /router-* slash commands also refresh themselves in the background about once a week (never overwriting a wrapper you edited). Opt out with WEAVE_STATUSLINE_UPDATE=0, or just the commands with WEAVE_COMMANDS_UPDATE=0. Codex installs native $ skills plus managed SessionStart/Stop hooks: the latest routed model is reflected in the terminal title and a compact Weave Router · … status message is shown when the router reports a new route. Existing Codex hooks are preserved. OpenCode and pi have their own target-specific integrations.

Version-pin for reproducible setups:

npx @weave-os/router@0.1.0 --claude --scope project

Switch on/off without uninstalling (keeps your config so switching back is instant; requires an explicit client):

npx @weave-os/router off --claude      # route Claude Code directly to Anthropic
npx @weave-os/router on --claude       # route Claude Code through the router again
npx @weave-os/router status --codex    # is Codex on the router or direct?

Claude Code reads its router setting at launch, so quit and reopen it after an on/off. Codex and opencode pick it up on their next run. Inside Claude Code the slash commands /router-off, /router-on, and /router-status do the same. Codex installs $router-status, $router-off, $router-on, and $router-models skills that call the same CLI verbs, plus a $disable-routing skill that switches its next session back to the normal provider; Codex does not support third-party /disable-routing slash commands. The shell equivalent is npx @weave-os/router disable-routing. Cursor has no config file we own — toggle its base URL override in Settings → Models instead.

Pick which models the router is allowed to route to:

npx @weave-os/router models --claude                  # list every model, with its on/off state
npx @weave-os/router models --codex                   # same, for a Codex install
npx @weave-os/router models disable gpt-5.6 --claude  # take one out of rotation
npx @weave-os/router models enable gpt-5.6 --claude   # put it back

Inside Claude Code that's /router-models (alias /models). Editing needs a router that serves the model-selection API; against the Weave-hosted router the list still prints and points you at the dashboard, where model selection is an organization-wide setting.

Uninstall:

npx @weave-os/router --uninstall                       # Claude Code, user scope
npx @weave-os/router --uninstall --codex               # Codex, user scope
npx @weave-os/router --uninstall --opencode            # opencode, user scope
npx @weave-os/router --uninstall --pi                  # pi, user scope
npx @weave-os/router --uninstall --scope project       # Claude Code, inside the repo
npx @weave-os/router --uninstall --codex --scope project

What it does

This package is a thin Node wrapper around install.sh from the Weave Router repo. It exists so you can install from any machine with Node ≥ 18 — no curl | sh, no Git clone, no PATH fiddling. Everything the shell installer documents (targets, scopes, flags, environment variables) works identically here.

Four install targets:

• Claude Code (default) — patches ~/.claude/settings.json (or <repo>/.claude/settings.json with --scope project) so claude routes through Weave automatically. Anthropic plan credentials flow through to api.anthropic.com.
• Codex (--codex) — patches ~/.codex/config.toml (or <repo>/.codex/config.toml) with a managed [model_providers.weave] block plus model_provider = "weave". The provider preserves the existing ChatGPT OAuth login. No install pins X-Weave-Router-Strategy; every endpoint keeps its router's configured default. HMM or forced gpt-5.6-sol, gpt-5.6-terra, and gpt-5.6-luna turns use that plan; every other selected model uses its WorkWeave deployment or BYOK credential. The block lives between begin/end markers so re-running the installer rewrites it cleanly and --uninstall --codex removes it without touching the rest of your config. Codex does not load third-party slash-command files; the installer provides native skills $force-model ($fm), $unforce-model ($ufm), and $router-feedback ($rf), each of which execs a local scripts/emit.sh that prints the same leading-space directive Claude Code uses (for example, /force-model gpt-5.6-terra) — you can also type that form directly. It also installs $router-status, $router-off, $router-on, and $router-models, which call this installer's own verbs, plus a $disable-routing skill that returns the next Codex session to the default provider without logging out or deleting the router configuration. The managed lifecycle hooks also keep the latest routed model in the terminal title and emit a compact status message when the router reports a new route.
• opencode (--opencode) — merges a provider.weave entry (backed by opencode's built-in @ai-sdk/anthropic provider) into ~/.config/opencode/opencode.json (or <repo>/opencode.json with --scope project). The router speaks the Anthropic Messages API natively, so opencode talks to it unmodified. Re-install rewrites only the managed provider.weave block; --uninstall --opencode strips it and leaves your other providers and settings alone.
• pi (--pi) — registers the weave provider and installs this package as a pi extension. Stock pi then gets the Loom startup header, Wooly's animated mascot, the persistent actual-route display, cumulative session savings, /fm + /ufm model-pin commands with a [forced] status, and the context-isolated dispatch tool. There is no forked pi binary and no separate Loom runtime.

See the main installer docs for the full reference.

Requirements

• Node ≥ 18 (ships with npx)
• bash on PATH (macOS / Linux native; Windows needs Git Bash or WSL)
• jq on PATH — used by the Claude Code status line, the Codex lifecycle helper, and the opencode/pi JSON merges.

Why npx

npx @weave-os/router gives Windows support via Git Bash, painless version pinning, and discoverability via the npm registry.

Older npm

On npm ≤ 6 the bundled npx treats an undeclared -y as consuming the next token, so npx -y @weave-os/router --claude silently drops the package name and resolves the following argument as the command instead. Either upgrade (npm i -g npm@latest) or name the binary explicitly:

npx --package @weave-os/router -y -- weave-router --claude

That form is correct on every npm version.
