At a glance

A skill your agent uses when reviewing CI coverage, automated checks, or test strategy related to Write integration tests for key workflows.

  • Reviewing CI coverage
  • SKILL.md covers Quick Reference, Check, Fix and Explain, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Automated checks

What it does

Integration Testing is an agent skill from thedaviddias/Front-End-Checklist. Use when reviewing CI coverage, automated checks, or test strategy related to Write integration tests for key workflows. Focus on whether the rule is continuously verified, not just documented.

Its SKILL.md is about 510 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/rule.md`).

It sits in Testing & QA, covering Integration testing. The repository describes itself as: 🗂 The essential checklist for modern web development, for humans and AI agents. The licence is MIT.

When your agent uses it

  • Reviewing CI coverage
  • Automated checks
  • Test strategy related to Write integration tests for key workflows

Example prompts

  • “/integration-testing”

What it can do on your machine

Read from SKILL.md and the folder at commit e8d14d0. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • frontendchecklist.io

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Integration Testing loads about 514 tokens when it runs, and up to ~1.5k if it reads all its reference files. Until then it costs about 53 tokens; SKILL.md has 222 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~53
When it runs · the whole SKILL.md, loaded when a task matches
~514
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Write integration tests for key workflows

Unit tests verify individual functions in isolation, but they can't catch the bugs that occur when those functions interact — a perfectly correct validation function and a correct database function can still fail when wired together incorrectly. Integration tests catch these wiring bugs before they reach production, where they're expensive to diagnose.

Quick Reference

  • Integration tests verify that multiple units work correctly together
  • Test at the boundary where different parts of your system meet
  • Use a real database in tests (test DB or in-memory) rather than mocking everything
  • Test happy paths and the most critical error paths

Check

Identify the key integration points in this codebase — where API routes call services, where services interact with the database, and where components interact with state management. Are these tested?

Fix

Write integration tests for the identified critical paths, testing the interactions between components rather than each in isolation.

Explain

Explain integration testing, how it differs from unit and E2E testing, and what tools to use for API and component integration tests.

Code Review

Review tests, CI workflows, and enforcement points related to Write integration tests for key workflows. Flag exact gaps where the rule is not automatically verified or where failures do not block regressions.
