smoke-testing

A guide for smoke testing, meaning checking that a user-visible action works on the deployed system and that diagnostics show no hidden failure.

In plain words
What is it for?
Use it to define smoke-test prompts for deployment handoffs or to run and assess those checks after deployment.
Why use it?
It prevents passing build checks or unit tests from being mistaken for proof that the live feature actually works.

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 A, and why

smoke-testing scanned grade A with 1 finding 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 176 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Smoke Testing

Style: Mode-B-lite. Outcome-first smoke discipline for Product Owner definition and AI Developer execution.

Purpose

Prevent pre-outcome signals from being mislabeled as smoke success. A smoke test passes only when the operator-visible action works on the deployed surface and the system's ground-truth diagnostics show no hidden failure.

When to invoke

  • Product Owner drafts verification-gate.md for a user-facing or operator-facing change.
  • Product Owner drafts docs/tmp/handoff/<date>-<slug>-deploy.md and includes S1..Sn smoke prompts.
  • AI Developer / Deploy phase runs post-deploy smoke prompts.
  • A previous smoke missed a production bug and the smoke method must be corrected.
  • Operator asks whether smoke evidence is sufficient.

Do not invoke when

  • The task is only pre-deploy source validation: lint, typecheck, unit tests, static bundle checks, file hash checks.
  • No deployed or runtime behavior exists to exercise.
  • A live user session is required but consent/session handling is not available; invoke workflows/live-user-verification.md first.

Required inputs

Input Where it lives If missing
Operator-visible success criterion verification-gate.md smoke section PO must write it before designing checks
Smoke prompts S1..Sn docs/specs/<slug>/verification-gate.md Stop; smoke cannot be improvised after deploy
Deployed surface / base URL / command deploy handoff Stop; ask PO to amend handoff
Ground-truth diagnostic surface smoke prompt field: logs, request dumps, DB row, rendered UI, response body Stop; PO must define it or explicitly mark unknown
Existing smoke harness docs/specs/<slug>/smoke.spec.ts, script path, curl command, or manual steps Use if present; do not substitute weaker checks silently
UI / browser plan, if applicable S fields or templates/smoke-test-playwright.md Require route, viewport, primary action, stable locators, auth plan, unique test data, expected outcome, diagnostics
CLI edition map, for Fusebase Apps work docs/fusebase-cli-edition.md Continue only if smoke can name another ground-truth diagnostic surface
Evidence directory docs/tmp/handoff/<date>-<slug>-smoke/ Create before execution

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-testing is a skill published in the GitHub repository fusebase-dev/fusebase-flow (9 stars, last pushed 7d ago), licensed MIT. It adds 60 tokens to every session and 3,353 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
