Where a new test belongs and how to scope CI jobs, steps, and workflow triggers so they run only when a change can affect them.

  • So they run only when a change can affect them
  • SKILL.md covers Why this is a cost question, Adding a test, Test workers and Adding or changing a CI job, plus 2 more sections
  • Calls pnpm, vitest and expo
  • Changing a CI job

What it does

Adding Tests And CI is an agent skill from BuilderIO/agent-native. Where a new test belongs and how to scope CI jobs, steps, and workflow triggers so they run only when a change can affect them. Use when adding or moving a test, adding or changing a CI job, step, or workflow, or when a job is slow or runs on unrelated changes.

Its SKILL.md is about 2.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Testing & QA. The repository describes itself as: A framework for building agentic apps.

When your agent uses it

  • So they run only when a change can affect them
  • Changing a CI job
  • Runs on unrelated changes

Example prompts

  • “/adding-tests-and-ci”

What it can do on your machine

Read from SKILL.md and the folder at commit e16da0c. 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

    Shell commands in SKILL.md call:

    • pnpm
    • vitest
    • expo
    • git
    • node

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

  • Network

    No URLs in SKILL.md. Its commands use pnpm and git, which can reach the network depending on how they are called.

    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

Adding Tests And CI loads about 2.3k tokens when it runs. Until then it costs about 70 tokens; SKILL.md has 1,387 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~70
When it runs · the whole SKILL.md, loaded when a task matches
~2.3k

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,387 words (~2,345 tokens).

“Every agent-native workflow draws on one org-wide pool of GitHub-hosted runners. On the Team plan it held 60 concurrent jobs, and on 2026-09-29 the Fast tests gate waited a median 445 s just for a slot. BuilderIO moved to Enterprise…”
