Yoetz Skill
Fast, agent-friendly LLM council tool for multi-model consensus, code review, and bundling.
When to Use
Explicit triggers only:
- "yoetz ask" / "yoetz council" / "yoetz review"
- "yoetz bundle" / "yoetz generate" / "yoetz browser"
- "use yoetz to..."
NOT triggered by:
- "second opinion" / "ask another model" (could be amq-cli)
- "council" alone / "review" alone (other skills may apply)
Installation (auto-bootstrap)
Before running any yoetz command, ensure the CLI is installed.
If command -v yoetz fails, install via one of the following:
| Platform | Command |
|---|
| macOS (Homebrew) | brew install avivsinai/homebrew-tap/yoetz |
| Linux (Homebrew if available) | brew install avivsinai/homebrew-tap/yoetz |
| From source (Rust 1.88+) | cargo install --git https://github.com/avivsinai/yoetz |
| Windows (Scoop) | scoop bucket add yoetz https://github.com/avivsinai/scoop-bucket && scoop install yoetz |
| Pre-built binary | Download from GitHub Releases and place in PATH |
Prefer Homebrew when available — pre-built binaries, fastest install.
Agent Contract
- Always use
--format json for parsing
- Set
YOETZ_AGENT=1 environment variable
- Parse JSON results and present summary to user
- For large bundles, run
yoetz bundle first to inspect size
- NEVER type a model ID from memory. Your training data model names are WRONG. Always resolve first.
Model Resolution Protocol (MANDATORY)
NEVER type a model ID from memory. Agent training data contains stale model names. Always query the live registry.
To find the current frontier model per provider:
yoetz models frontier --format json
To find a specific model:
yoetz models resolve "grok" --format json
Use the returned ID verbatim in your commands. Do not modify, shorten, or guess model IDs.
If the registry is stale or empty, sync first:
yoetz models sync
Search for models by keyword:
yoetz models list -s claude --format json
Quick Reference
| Task | Command |
|---|
| Find frontier model per provider | yoetz models frontier --format json |
| Find frontier model for a provider | yoetz models frontier --family openai --format json |
| Resolve a model ID | yoetz models resolve "grok" --format json |
| Search models | yoetz models list -s claude --format json |
| Ask single model | yoetz ask -p "question" -f src/*.rs --provider openai --model MODEL_ID --format json |
| Council vote | yoetz council -p "question" --models MODEL1,MODEL2,MODEL3 --format json |
| Review staged diff | yoetz review diff --staged --format json |
| Review file | yoetz review file --path src/main.rs --format json |
| Bundle files | yoetz bundle -p "context" -f src/**/*.rs --format json |
| Generate image | yoetz generate image -p "description" --provider openai --model MODEL_ID --format json |
| Estimate cost | yoetz pricing estimate --model MODEL_ID --input-tokens 1000 --output-tokens 500 |
| Browser check | yoetz browser check |
| Browser attach | yoetz browser attach |
| Browser login | yoetz browser login |
Replace MODEL_ID with IDs from yoetz models frontier or yoetz models resolve.
Council (Multi-Model Consensus)
Get opinions from multiple LLMs in parallel. --models is required.
yoetz council \
-p "Should we use async traits or callbacks for this API?" \
-f src/lib.rs -f src/api/*.rs \
--models openai/gpt-5.4,gemini/gemini-3.1-pro-preview,openrouter/xai/grok-4.20-multi-agent-beta \
--format json
Example council sets (illustrative — always resolve live IDs via yoetz models frontier):
- Cross-provider:
openai/<FRONTIER>,gemini/<FRONTIER>,openrouter/xai/<FRONTIER>
- Via OpenRouter only:
openrouter/openai/<FRONTIER>,openrouter/anthropic/<FRONTIER>,openrouter/google/<FRONTIER>
Ask (Single Model)
Quick question with file context:
yoetz ask \
-p "What's the bug in this error handling?" \
-f src/error.rs \
--provider openai --model gpt-5.4 \
--format json
For Anthropic/XAI models, use OpenRouter (no extra config needed):
yoetz ask -p "Review this" -f src/*.rs \
--provider openrouter --model anthropic/claude-sonnet-4.6 \
--format json
Review
Staged changes
yoetz review diff --staged --format json
Specific file
yoetz review file --path src/main.rs --format json
With custom model
yoetz review diff --staged --provider openai --model gpt-5.4 --format json
Bundle (for manual paste or browser mode)
Bundle creates a session with files at ~/.yoetz/sessions/<id>/bundle.md.
yoetz bundle -p "Explain this" -f src/**/*.rs --format json
BUNDLE=$(yoetz bundle -p "Review" -f src/*.rs --format json | jq -r .artifacts.bundle_md)
cat "$BUNDLE"
For browser workflows, pass the bundle.md path:
BUNDLE=$(yoetz bundle -p "Review" -f src/*.rs --format json | jq -r .artifacts.bundle_md)
yoetz browser recipe --recipe chatgpt --bundle "$BUNDLE"
Browser Mode
For web-only models like ChatGPT Pro that lack API access. Connects to your running Chrome via CDP (Chrome DevTools Protocol) to submit bundles through the web UI.
Prerequisites
npm install -g dev-browser
npm install -g agent-browser
How connection works
yoetz connects to your already logged-in Chrome session via auto-connect (CDP). No cookie extraction or separate browser needed.
Transport priority: chrome-devtools-mcp > dev-browser > agent-browser > manual browser upload.
Connection priority: explicit --cdp > auto-connect > cookie state > profile fallback.
Use --cdp http://127.0.0.1:9222 when you need to target a specific Chrome instance/profile.
First-time setup
Step 1: Enable remote debugging in Chrome
- Open Chrome and go to
chrome://inspect/#remote-debugging
- Ensure "Discover network targets" is enabled
If Chrome lands on chrome://inspect/#devices instead, that's fine. Keep "Discover network targets" enabled there.
Step 2: Run a recipe
BUNDLE=$(yoetz bundle -p "Review" -f src/*.rs --format json | jq -r .artifacts.bundle_md)
yoetz browser recipe --recipe chatgpt --bundle "$BUNDLE"
Step 3: Approve remote debugging (Chrome 146+)
Chrome 146+ may show an "Allow remote debugging?" dialog on the first live attach. Click Allow once for that browser instance.
Step 4: Verify connection
yoetz browser attach
Chrome 146+ notes
Chrome 146 introduced a security dialog for external CDP connections. Yoetz is extension-free by design, so the only way to get "approve once, then run silently" behavior is to keep the daemon/CDP session alive and avoid tearing it down between invocations.
Current policy:
- Prefer live attach over cookie sync:
chrome-devtools-mcp first, dev-browser second, agent-browser third.
- Trust an existing live-attach daemon by default; yoetz does not silently recycle it during normal attach/check/recipe flows.
- If recovery is actually needed, use
yoetz browser reset explicitly.
If you see "Allow remote debugging?" in Chrome, click Allow and retry.
Explicit --cdp is already supported on yoetz browser attach, check, recipe, and login, but it only bypasses auto-discovery. It does not bypass Chrome's approval gate when targeting the same live browser instance started from chrome://inspect.
If the approval dialog is frozen or unclickable, use the manual CDP path instead:
chrome --remote-debugging-port=9222 --user-data-dir=/tmp/chrome-debug
yoetz browser attach --cdp http://127.0.0.1:9222
Chrome for Testing is also a good fallback for this manual path.
Cookie sync (legacy fallback)
If auto-connect isn't available, cookie sync is still supported:
yoetz browser sync-cookies
yoetz browser check
Requires Node >= 24.4. If macOS shows a Keychain prompt for Chrome Safe Storage, click Always Allow.
Use ChatGPT Pro via recipe
BUNDLE=$(yoetz bundle -p "Review this code" -f src/*.rs --format json | jq -r .artifacts.bundle_md)
yoetz browser recipe --recipe chatgpt --bundle "$BUNDLE"
yoetz browser recipe --recipe chatgpt --bundle "$BUNDLE" --var model=gpt-5-4-pro
yoetz browser recipe --recipe chatgpt --bundle "$BUNDLE" --var thread=reuse
The wait loop reports completion_reason in its JSON output:
copy_button — the strong signal: a copy control rendered on the new
assistant message (response is fully streamed).
stable_idle_fallback — the page looked idle with unchanged length for
≥ max(90s, 3 × wait_interval_ms). Used when ChatGPT changes its copy-button
selectors; otherwise copy_button is the normal completion path.
Combined workflow: API + Browser
yoetz council -p "Review" -f src/*.rs \
--models openai/gpt-5.4,gemini/gemini-3.1-pro-preview --format json > api.json
BUNDLE=$(yoetz bundle -p "Review" -f src/*.rs --format json | jq -r .artifacts.bundle_md)
yoetz browser recipe --recipe chatgpt --bundle "$BUNDLE"
Recipe name resolution
Recipes can be specified by name (resolved from installed locations) or by path:
yoetz browser recipe --recipe chatgpt --bundle "$BUNDLE"
yoetz browser recipe --recipe ./my-recipes/custom.yaml --bundle "$BUNDLE"
Built-in recipes: chatgpt, claude, gemini.
Troubleshooting
| Symptom | Fix |
|---|
Allow remote debugging? dialog | Click Allow in Chrome, then retry. If the dialog is frozen, launch Chrome with --remote-debugging-port=9222 --user-data-dir=/tmp/chrome-debug and use yoetz browser attach --cdp http://127.0.0.1:9222 instead. |
auto-connect probe timed out | Chrome dialog is probably showing. Click Allow. If Chrome will not accept the dialog, switch to the explicit --cdp flow above. Install dev-browser first; agent-browser remains a fallback. |
chatgpt login required | Chrome was reached but the wrong profile/tab was used. Open ChatGPT in the target Chrome profile first, or connect that profile explicitly with --cdp, then retry. |
daemon already running | Run yoetz browser attach to check connection. If the daemon is stale, use yoetz browser reset, not agent-browser close directly. |
agent-browser failed | Ensure npx agent-browser --version works, or npm install -g agent-browser |
dev-browser failed | Ensure dev-browser --help works, verify Chrome remote debugging is enabled, and retry with --cdp if you need a specific Chrome profile. |
| Recipe not found | Use --recipe chatgpt (name) or full path. Check brew --prefix/share/yoetz/recipes/ |
cookie extraction failed | Legacy path: ensure Node >= 24.4, log into ChatGPT in Chrome, close Chrome, yoetz browser sync-cookies |
dev-browser Fallback
When yoetz browser recipe needs manual browser automation, use dev-browser directly against the authenticated Chrome session:
- Create bundle:
BUNDLE=$(yoetz bundle -p "Review" -f src/**/*.ts --format json | jq -r .artifacts.bundle_md)
- Connect to Chrome:
dev-browser --connect <<'EOF'
const page = await browser.getPage("chatgpt");
await page.goto("https://chatgpt.com/");
console.log(await page.title());
EOF
- Use the Playwright-style API:
browser.getPage(name), page.goto(url), page.click(selector), page.fill(selector, text), page.evaluate(fn), page.title()
- Use file helpers when needed:
saveScreenshot(buf, name), writeFile(name, data), readFile(name)
- Target a specific Chrome profile: prefer opening ChatGPT in that profile first, or connect to its explicit CDP endpoint with
yoetz browser recipe --cdp http://127.0.0.1:9222 ...
This keeps the default path aligned with the same browser transport users already rely on outside Yoetz.
How it works
The browser module connects to your running Chrome via CDP (Chrome DevTools Protocol):
- chrome-devtools-mcp (primary): built into yoetz, backed by
headless_chrome, attaches directly to your logged-in Chrome session
- dev-browser (fallback): Playwright-based transport for the same live-attach flow
- agent-browser (fallback 2): browser automation fallback with cookie/profile fallback support
- Cookie sync (final fallback): extracts cookies from Chrome's encrypted store, injects into agent-browser only after live attach paths are exhausted
- Extension-free by design: no browser extension is required or desired
- Daemon model: one persistent connection per session, reused across invocations until you explicitly run
yoetz browser reset
Provider Configuration
Built-in providers (work with just env var):
openai - OPENAI_API_KEY
gemini - GEMINI_API_KEY
openrouter - OPENROUTER_API_KEY
Via OpenRouter (recommended for Anthropic/XAI - no extra config):
openrouter/anthropic/claude-sonnet-4.6
openrouter/xai/grok-4.20-multi-agent-beta
Model format: provider/model
openai/gpt-5.4
gemini/gemini-3.1-pro-preview
openrouter/anthropic/claude-sonnet-4.6 (nested for OpenRouter)
Cost Control
yoetz pricing estimate --model gpt-5.4 --input-tokens 12000 --output-tokens 800
yoetz ask -p "Review" --max-cost-usd 1.00 --daily-budget-usd 5.00 --format json
Tips
- Use
--debug to capture raw responses during troubleshooting
- Gemini may return empty content if
--max-output-tokens is too low
- Session artifacts stored in
~/.yoetz/sessions/<id>/
- For image inputs:
yoetz ask -p "Describe" --image photo.png --format json
- ChatGPT recipe placeholder may vary by locale; check snapshot output if fill fails
