yoetz

Fast CLI for routing code and media work through the right LLM path: direct API calls when available, multi-model councils when you need agreement, and browser recipes for web-only models such as ChatGPT Pro and Claude's Fable 5.

Yoetz is built for coding agents and terminal workflows: gitignore-aware bundles, structured JSON output, reproducible session artifacts, live model resolution, local budget checks, and multimodal inputs across OpenAI, OpenRouter, Gemini, and LiteLLM-compatible backends.

Yoetz is under active development. Command behavior may change before 1.0.

What It Does

• Bundle repository context into prompt-ready artifacts without fighting .gitignore.
• Ask one model with text, code, images, or video.
• Council multiple models in parallel when you want independent opinions.
• Review staged diffs or files with agent-readable output.
• Generate images and video through providers that expose generation APIs.
• Use browser recipes for web-only model surfaces while keeping terminal output parseable.

Agent Skills

Yoetz also ships an agent skill so Claude Code, Codex CLI, and compatible agent runtimes know how to call the CLI safely: resolve live model IDs, keep stdout parseable, bundle large context first, and use browser recipes intentionally.

The skill source lives at skills/yoetz/SKILL.md and is versioned with the CLI release metadata.

First Run

Start with a command that needs no API key:

yoetz bundle -p "Summarize this project" -f README.md --format json

Then configure at least one provider. Environment variables are enough for most users:

export OPENROUTER_API_KEY=...
export OPENAI_API_KEY=...
export GEMINI_API_KEY=...

For persistent configuration:

mkdir -p ~/.config/yoetz
cat > ~/.config/yoetz/config.toml <<'EOF'
[defaults]
provider = "openrouter"
# Optional after resolving a current model ID:
# model = "<id from yoetz models resolve>"

[providers.openrouter]
base_url = "https://openrouter.ai/api/v1"
api_key_env = "OPENROUTER_API_KEY"
kind = "openai-compatible"
EOF

From a source checkout, you can start from the full example instead:

cp docs/config.example.toml ~/.config/yoetz/config.toml

Yoetz also supports YOETZ_CONFIG_PATH, repo-local ./yoetz.toml, and config profiles. See docs/config.example.toml for the shape.

The default models frontier lab list is configurable with [frontier].families; --all and --family continue to bypass that list.

yoetz ask writes artifacts to ~/.yoetz/sessions/<id>/ by default. Headless callers can skip that entirely with yoetz ask --no-session (or [sessions] no_session = true), and [sessions] max_age_days / [sessions] max_count prune old or excess session dirs on startup. Both are off by default, and [sessions] is only honored from trusted config locations, never from repo-local ./yoetz.toml. A max_count of 0 removes all completed sessions while preserving active writers. A legacy session with no lease file is left alone for its first five minutes to avoid racing a writer that has just created the directory. In JSON output, --no-session emits session_dir: "" and response_json: null; artifact consumers must handle those values without constructing a path.

Resolve live model IDs before putting them in scripts:

yoetz models sync
yoetz models frontier --format json
yoetz models frontier --family anthropic --format json

Common Workflows

Ask With File Context

MODEL_ID=$(yoetz models frontier --family openai --format json | jq -r '.[0].model.id')
yoetz ask \
  -p "Explain the error handling tradeoffs in this file" \
  -f crates/yoetz-cli/src/main.rs \
  --provider openrouter \
  --model "$MODEL_ID" \
  --format json

Review A Diff

yoetz review diff --staged --format json
yoetz review file --path crates/yoetz-core/src/bundle.rs --format json

Run A Council

OPENAI_MODEL=$(yoetz models frontier --family openai --format json | jq -r '.[0].model.id')
GEMINI_MODEL=$(yoetz models frontier --family gemini --format json | jq -r '.[0].model.id')
XAI_MODEL=$(yoetz models frontier --family xai --format json | jq -r '.[0].model.id')

yoetz council \
  -p "Which API shape is safer for agents?" \
  -f crates/yoetz-core/src/types.rs \
  --models "$OPENAI_MODEL,$GEMINI_MODEL,$XAI_MODEL" \
  --format json

--models is explicit on purpose. Pick current IDs from yoetz models frontier or yoetz models resolve, and pass the returned IDs verbatim. Avoid using stale provider names or hand-written wrapper paths.

Bundle For Another Tool

yoetz bundle \
  -p "Review the browser transport design" \
  -f "crates/yoetz-cli/src/browser*.rs" \
  -f recipes/chatgpt.yaml \
  --format json

The JSON response points to session artifacts under ~/.yoetz/sessions/<id>/, including bundle.md.

Multimodal Input

MODEL_ID=$(yoetz models resolve "gemini" --format json | jq -r '.[0].id')
yoetz ask -p "Describe this diagram" --image diagram.png --provider gemini --model "$MODEL_ID" --format json
yoetz ask -p "Summarize this clip" --video demo.mp4 --provider gemini --model "$MODEL_ID" --format json

Use --image-mime or --video-mime for signed URLs or extensionless files.

Generate Media

IMAGE_MODEL_ID=$(yoetz models list -s image --format json | jq -r '.models[] | .id | select(startswith("gemini/")) | sub("^gemini/"; "")' | head -1)
yoetz generate image \
  -p "A clean product diagram of a terminal-first LLM router" \
  --provider gemini \
  --model "$IMAGE_MODEL_ID" \
  --format json

VIDEO_MODEL_ID=$(yoetz models list -s veo --format json | jq -r '.models[] | .id | select(startswith("gemini/")) | sub("^gemini/"; "")' | head -1)
yoetz generate video \
  -p "A short UI walkthrough" \
  --provider gemini \
  --model "$VIDEO_MODEL_ID" \
  --format json

Generation still requires a provider-specific --provider plus a model that that provider accepts. List or resolve live models before pinning a script.

Agent Usage

Yoetz is designed to be called by agents and scripts.

export YOETZ_AGENT=1
yoetz ask -p "Return JSON only" -f src/lib.rs --format json --output-final /tmp/yoetz-result.json

Useful agent-facing guarantees:

• --format json keeps stdout parseable.
• --response-format json and --response-schema request model-side structured output; --format json only controls the Yoetz CLI envelope.
• Progress and diagnostics use stderr where possible.
• --output-final writes the final response to a stable path.
• ask, bundle, council, and review create replayable session artifacts.
• Budget flags such as --max-cost-usd and --daily-budget-usd are local preflight/accounting aids, not provider-side hard limits.

Agent skill installation options are listed in Agent Skills.

Browser Recipes: ChatGPT Pro And Claude

Browser recipes let Yoetz use web-only model surfaces from the terminal. The built-in ChatGPT recipe targets GPT-5.6 Sol at the account's known top tier (Pro or Extra High) and is fail-closed: if Yoetz cannot prove the requested surface is available, it stops instead of silently downgrading. The built-in Claude recipe applies the same contract to claude.ai with exactly Fable 5 and Effort Max.

yoetz browser check --format json
yoetz browser recipe --recipe chatgpt --bundle ~/.yoetz/sessions/<id>/bundle.md --format json
yoetz browser check --claude --format json
yoetz browser recipe --recipe claude --bundle ~/.yoetz/sessions/<id>/bundle.md --format json

Both recipes support chrome-devtools-mcp, dev-browser, agent-browser, and chrome-extension-native. The default browser stack is extension-free unless a connected native extension advertises the selected site. That recipe then selects chrome-extension-native as its only default transport and fails closed. Use an explicit --transport <name> to select another browser transport.

The native path is one pinned multi-site package named Yoetz Native Transport, so existing ChatGPT installations keep the same extension ID and gain Claude support without re-pairing. Choose the site scope when managing or checking it:

yoetz browser extension setup --chatgpt --open-chrome
yoetz browser extension doctor --chatgpt
yoetz browser extension status --chatgpt --format json
yoetz browser recipe --recipe chatgpt --transport chrome-extension-native --bundle bundle.md --format json

yoetz browser extension setup --claude --open-chrome
yoetz browser extension doctor --claude
yoetz browser extension status --claude --format json
yoetz browser extension canary --claude
yoetz browser recipe --recipe claude --transport chrome-extension-native --bundle bundle.md --format json

Load the managed $YOETZ_DIR/chatgpt-native-extension directory unpacked in the Chrome profile that hosts the target AI sessions; do not load a repo checkout. Setup, update, and reload share machine-global native-host and managed extension state. Recipe runs hold a shared lifecycle lock; setup, update, reload, and auto-heal require its exclusive side and fail with extension_lifecycle_busy instead of changing the loaded artifact mid-run.

Independent ChatGPT and Claude recipe runs may share one connected extension profile: each job owns a separate background tab, and profile selectors are routing controls, not a prerequisite for parallelism. On released v0.5.42, a live run proved exactly two concurrent Claude recipes in one connected profile on an Enterprise workspace account. The jobs overlapped for 125s and used distinct conversations. Both verified Fable 5 and Effort Max. Tab non-activation has separate evidence: the released adapter sets activateOnCreate:false, a single-job live probe measured tab_active=false at every phase, and service-worker coverage asserts that no tab activation call occurs. The concurrency evidence covers two jobs, not higher fanout or other account types. Service-worker coverage separately proves two Claude jobs use distinct background tabs through overlapping phases and that cancelling one does not affect the other. Both sites may run only against one frozen loaded artifact. Give each parallel recipe its own Yoetz bundle session directory; reusing one managed bundle.md fails with session_busy rather than overwriting that session's response.json or followup.json.

Upgrade the installed CLI before another lane runs extension auto-heal after a release. An older CLI can overwrite the newer stamped managed copy.

Claude conversation resume supports --var conversation=<uuid|url> and --followup on the native transport. inline_warn_tokens defaults to 150,000 and warns when a bundle is likely to become retrieval-backed; set it to 0 to disable the heuristic. This warning does not change Yoetz's byte limits.

The native-host extension transport is currently macOS/Linux-only. Windows CLI and Scoop installs work for the API-backed Yoetz flows, but chrome-extension-native setup fails closed until Windows native messaging host registration is implemented.

For multiple loaded Chrome profiles, select the connected bridge with --var extension_instance_id=<id> from yoetz browser extension status --chatgpt (or --claude), or opt into profile_email routing with yoetz browser extension grant-identity --chatgpt (or --claude).

The detailed browser transport model lives in ARCHITECTURE.md.

Provider Support

Capabilities vary by model and provider. Use yoetz models frontier, yoetz models list, and yoetz models resolve against the live registry before pinning examples.

Provider	Text	Vision	Image Gen	Video Gen	Video Understanding
OpenRouter	Yes	Model-dependent	No	No	No
OpenAI	Yes	Yes	Yes	Yes (Sora)	No
Gemini	Yes	Yes	No	Yes (Veo)	Yes
Z.AI	Yes	Model-dependent	No	No	No
LiteLLM-compatible	Yes	Model-dependent	No	No	No

Anthropic, xAI, and Z.AI models are commonly reached through OpenRouter, but can also be configured as direct providers when you need provider-specific routing.

Common API key variables:

Variable	Used for
OPENROUTER_API_KEY	OpenRouter
OPENAI_API_KEY	OpenAI
GEMINI_API_KEY	Gemini
ANTHROPIC_API_KEY	Direct Anthropic-compatible provider configs
XAI_API_KEY	Direct xAI/OpenAI-compatible provider configs
ZAI_API_KEY	Direct Z.AI/OpenAI-compatible routing
LITELLM_API_KEY	LiteLLM proxy

Safety And Trust

Bundles are prompt-input artifacts, not trusted control channels. Treat bundled repository content, issues, logs, and pasted browser output as untrusted input. Keep intent in explicit CLI flags and the user prompt, avoid bundling secrets, and review generated changes before applying them.

Project trust signals:

• CI covers Rust tests, formatting, linting, dependency policy, secret scanning, MSRV, extension script tests, and browser smoke checks.
• Release archives ship with SHA256SUMS.txt.
• Security policy: SECURITY.md.
• Code of conduct: CODE_OF_CONDUCT.md.

Development

git clone https://github.com/avivsinai/yoetz.git
cd yoetz
