dev-smoke

dev-smoke is a skill for Claude Code, Codex from codeaholicguy/ai-devkit. It costs 73 tokens per session (891 once invoked), scanned A, original, Apache-2.0.

An end-to-end smoke check runs the real application through the user flows affected by a change, using a temporary isolated script. It can cover a command-line tool, API, screen, or background job.

In plain words
What is it for?
Use it before declaring a feature or fix complete, especially when unit tests pass but the whole flow has not been checked. It reports what could not be tested if the application cannot run locally.
Why use it?
It catches broken user flows that unit tests may miss. It also avoids risking production systems by using temporary data, accounts, settings, and files.

About the project

AI DevKit is a local-first control layer that gives multiple AI coding agents shared configuration, a terminal dashboard, cross-agent messaging, local memory retrieval, and reusable engineering workflows. It is for developers and teams supervising agents such as Claude Code, Codex CLI, Gemini CLI, OpenCode, Pi, Cursor, Copilot, or Devin. The catalogue entries are composable skills and plugin components used within that agent-management system.

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

dev-smoke scanned grade A with 0 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 4d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (references/smoke-template.sh, references/web-smoke-template.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 43 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Smoke

Exercise the flows a change touches the way a user would, then throw the script away. Report with verify; use dev-testing for permanent tests.

Rules

  • Drive the real entry point: built binary, running server, CLI, UI, or job. Imported functions and mocks are not smoke checks.
  • Sandbox everything: temp dir, isolated HOME and config, empty git hooks, seeded test data, test accounts and tokens.
  • Never use production, shared environments, real accounts or credentials, or paid APIs. Ask before outward-facing side effects: messages, emails, webhooks, deploys, pushes.
  • Start servers on a dedicated port, wait until they respond, and stop the whole process tree on exit. Never reuse or kill the user's own servers.
  • Keep secrets out of the script and its output.
  • Write the script outside the repo; commit it only if the user asks to promote it.
  • Timebox setup. If the app cannot run locally, say what was not checked instead of faking a pass.

Workflow

  1. Read the change: git diff against the base branch, plus untracked files.
  2. Map impact outward: changed symbols -> callers -> entry points (commands, routes, screens, jobs, hooks, config, migrations) -> user flows. Add adjacent flows sharing the changed code, config, or data; note skipped flows and why.
  3. List scenarios as setup / action / expected result, ordered by risk. Wait for the user to add or cut flows; when running unattended, proceed and include the list in the report.
  4. Search memory for known setup: npx ai-devkit@latest memory search --query "<project> smoke setup" --tags "smoke". Build once, then write the script from references/smoke-template.sh (CLI, API) or references/web-smoke-template.mjs (browser). Each check asserts output, files, HTTP status, or exit code, not just "it ran"; API checks also assert the body and one error case (bad input, missing auth). Print PASS/FAIL per check and exit non-zero on any failure.
  5. Run it and read the full output.
  6. On a failure, first rule out a wrong check (selector, timing, setup), then rerun it on the base commit in a separate worktree (dev-worktree) to separate regressions from pre-existing failures.
  7. Report with verify: scenarios, command, exit code, per-check result, pre-existing failures, flows not covered.
  8. Delete the script and sandbox, or offer to promote valuable checks into permanent tests or the project's release smoke suite. Store non-obvious setup: npx ai-devkit@latest memory store --title "<project> smoke setup" --content "<start command, port, health URL, seeding, traps>" --tags "smoke".

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.
