smoke-test

A browser-based smoke-testing tool for checking that a web app’s main pages and API health endpoints work after starting the development server. Smoke testing is a quick check for obvious failures.

In plain words
What is it for?
It is for testing frontend routes, API endpoints, optional create-and-edit flows, and screenshots with Playwright, a browser automation tool.
Why use it?
It catches broken pages, console errors, and failed network requests before changes are shared or reviewed.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

smoke-test scanned grade C with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

How it starts

The opening of the file, as written. The whole thing — 196 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Smoke Test

Navigate key application routes using Playwright and verify they render without errors.

Arguments

  • --frontend-only — Only test frontend routes (skip API health checks)
  • --api-only — Only test API health endpoints
  • --interactive — Run interactive CRUD flows after route testing (creates test data)
  • --screenshot — Take screenshots of each page (saved to /tmp/smoke-test/)
  • {url} — Test a specific URL instead of the default routes

Configuration

Read cloudstack.json from the project root at the start of execution. Extract:

  • FRONTEND_PATH = frontend.path (default: web)
  • DEV_PORT = frontend.devPort (default: 5173)
  • UI_LIBRARY = frontend.uiLibrary (default: shadcn)
  • STATE_SERVER = frontend.stateManagement.server (default: tanstack-query)
  • STATE_CLIENT = frontend.stateManagement.client (default: zustand)
  • MULTI_TENANT = backend.multiTenancy (default: false)

Also extract:

  • API_PORT = backend.devPort (default: 5000)
  • ORCHESTRATOR = localDev.orchestrator (default: none) — e.g., aspire, docker-compose, none
  • ORCHESTRATOR_PORT = localDev.orchestratorPort (default: none)

If cloudstack.json does not exist, auto-detect by checking package.json dependencies.

Auth Configuration

Check cloudstack.json for localDev.authConfig. If present, use it. Otherwise, detect the auth store pattern from the codebase (see screenshot skill for details).

Prerequisites

The local environment must be running. If not, suggest starting the dev server first.

Process

Step 1: Verify Services Are Up

Check that the expected ports are responding before running browser tests:

# Check API
curl -sf http://localhost:{API_PORT}/health/live > /dev/null 2>&1 && echo "API: UP" || echo "API: DOWN"

# Check Frontend
curl -sf http://localhost:{DEV_PORT} > /dev/null 2>&1 && echo "Frontend: UP" || echo "Frontend: DOWN"

If ORCHESTRATOR is set (e.g., aspire, docker-compose), also check the orchestrator dashboard:

# Only if ORCHESTRATOR_PORT is configured
curl -sf http://localhost:{ORCHESTRATOR_PORT} -k > /dev/null 2>&1 && echo "Orchestrator: UP" || echo "Orchestrator: DOWN"

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

smoke-test is a skill published in the GitHub repository makigjuro/cloudstack-ai-plugins (1 stars, last pushed 1mo ago), licensed MIT. It adds 44 tokens to every session and 1,965 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
