agent-browser CLI — headless Chromium for AI agents. Snapshot-and-ref workflow, core commands, and yai service interaction patterns. Auto-load when asked to open a browser, navigate a URL, click, fill, screenshot, or interact with any yai web UI (Grafana, n8n, Windmill, Langfuse, MinIO, etc.).
Browserless headless Chromium service on the yai stack — REST endpoints (screenshot, PDF, scrape, function), WebSocket CDP/Puppeteer/Playwright patterns, token auth, sizing. Auto-load on Browserless, headless browser, Puppeteer, Playwright, CDP, screenshot, PDF, scrape-script questions.
Generate clean architecture / flow diagrams as PNG+SVG for the yai stack. Hand-laid-out Python→SVG→PNG pipeline (no Mermaid auto-layout). Auto-load when asked to create, update, or render an architecture diagram, flow chart, system diagram, or "draw the stack".
Firecrawl web crawling & scraping API on the yai stack — scrape, crawl, extract endpoints, job status, concurrency knobs, proxy config. Auto-load on Firecrawl, web scrape, crawl, extract, markdown, web content questions.
Grafana on the yai stack — datasource UIDs, file provisioning (not TF), dashboard conventions, scrape targets page, Grafana plugin setup. Auto-load on Grafana, dashboard, datasource, DS_*, panel, templating variable, provisioning questions.
How to control every yai web UI — login recipes, navigation patterns, and common actions for Grafana, Langfuse, MinIO, n8n, Windmill, LiteLLM, Qdrant, and Traefik. Auto-load when asked to log in, navigate, click, or perform any action in a yai service UI.

OTLP ingest + Jaeger-compatible query API. URL in env: YAI_VTRACES_URL
(port 21428).
# Jaeger endpoint (for Grafana datasource and queries)
YAI_VTRACES_JAEGER_URL="${YAI_VTRACES_URL}/select/jaeger"
# OTLP ingest (from other services)
http://localhost:21428/insert/opentelemetry/v1/traces
# From inside another compose network:
http://host.docker.internal:21428/insert/opentelemetry/v1/traces
VictoriaTraces is still on a v0.x release line — read the release
notes before bumping the version in grafana/.env.
Configure these env vars in each service's .env to ship OTLP traces:
OTEL_EXPORTER_OTLP_TRACES_ENDPOINT=http://host.docker.internal:21428/insert/opentelemetry/v1/traces
OTEL_EXPORTER_OTLP_PROTOCOL=http/protobuf
| Service | Native OTLP support | service.name in traces |
|---|---|---|
| LiteLLM | Yes (built-in) | litellm |
| Langfuse | Yes (worker) | langfuse |
| n8n | Yes (OTEL env vars) | n8n |
| Windmill | Yes (OTEL env vars) | windmill |

OTEL_EXPORTER_OTLP_PROTOCOL=grpc.jaeger, pointed at YAI_VTRACES_JAEGER_URL.http://host.docker.internal:21428/insert/opentelemetry/v1/traces (not localhost from inside a container). Verify with curl -s http://localhost:21428/api/v2/services.trace_id via OTLP when success_callback: ["langfuse"] is set. The Langfuse trace ID and the vtraces span ID share a root — search by the same trace_id in both systems.
