Test Writing Workflow
iOfficeAI/AionUi
Sets the test-writing workflow for the repository: risk-first scenario lists, behavior-focused Vitest tests, a full run before each commit and a coverage target.
A skill your agent uses when writing or modifying Vitest tests, .vitest setup, Anvil/Foundry or Rundler fixtures, per-package test config, or CI affected-test behavior.

What it does
Testing is an agent skill from alchemyplatform/aa-sdk. Use when writing or modifying Vitest tests, .vitest setup, Anvil/Foundry or Rundler fixtures, per-package test config, or CI affected-test behavior.
Its SKILL.md is about 310 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files (for example `rules/affected-tests.md`, `rules/anvil-and-rundler.md` and `rules/vitest-workspace.md`).
It sits in Testing & QA, covering Unit testing. It works with Vitest. The licence is MIT.
When your agent uses it
- Modifying Vitest tests
- Rundler fixtures
- Per-package test config
- CI affected-test behavior
Example prompts
- “/testing”
What it can do on your machine
Read from SKILL.md and the folder at commit 2d60342. 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
No URLs in SKILL.md.
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
Testing loads about 305 tokens when it runs. Until then it costs about 40 tokens; SKILL.md has 82 words of instructions outside code blocks.
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.

Testing
aa-sdk uses Vitest workspace projects with shared .vitest setup. CI runs
affected package tests and a separate typecheck-only Vitest pass.
Rules
| Rule | When to read |
|---|---|
| Vitest projects | Before changing tests or per-package Vitest config. |
| Anvil and Rundler | Before changing tests that depend on local chain fixtures. |
| Affected tests | Before choosing local verification for package changes. |

Questions about Testing
What does Testing do?
A skill your agent uses when writing or modifying Vitest tests, .vitest setup, Anvil/Foundry or Rundler fixtures, per-package test config, or CI affected-test behavior. Testing is an agent skill from alchemyplatform/aa-sdk.vitest setup, Anvil/Foundry or Rundler fixtures, per-package test config, or CI affected-test behavior.
When should I use Testing?
Testing fits situations like: modifying Vitest tests; rundler fixtures; per-package test config; CI affected-test behavior.
How do I install Testing in Claude Code?
Run `npx skills add alchemyplatform/aa-sdk --skill testing -a claude-code`. Or copy the skill folder (.agents/skills/testing in alchemyplatform/aa-sdk) into .claude/skills/testing in your project. Claude Code loads it when a task matches its description.
How do I install Testing in Codex?
Run `npx skills add alchemyplatform/aa-sdk --skill testing -a codex`. Or copy the skill folder (.agents/skills/testing in alchemyplatform/aa-sdk) into .agents/skills/testing in your project. Codex loads it when a task matches its description.
Can I use Testing in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add alchemyplatform/aa-sdk --skill testing -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/testing, .gemini/skills/testing, .github/skills/testing and .opencode/skills/testing in your project.
What does Testing need to run?
SKILL.md names no scripts, command-line tools or credentials: Testing is instructions for the agent only.
Does Testing access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Testing safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Testing use?
Testing is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Testing use?
About 305 tokens (SKILL.md is roughly 1.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Testing?
Skills that share tags, products or a category with Testing: Test Writing Workflow (iOfficeAI/AionUi, 33k stars), Vitest (supabase/supabase, 111k stars), Test Guard (amElnagdy/guard-skills, 1.3k stars) and Control UI E2E (openclaw/openclaw, 392k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
