What it does

Testing is an agent skill from kortix-ai/suna. Use for every Kortix test task, behavior change, bug fix, refactor, API route change, CLI change, SDK change, browser journey, test failure, coverage question, local benchmark, or testing infrastructure change. Enforce the single local-first runner, black-box flow contracts, package-local SDK tests, browser-only Playwright tests, and real input/output verification.

Its SKILL.md is about 3.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `agents/openai.yaml`, `references/api-latency-baseline.md` and `references/e2e-evaluation.md`).

It sits in Testing & QA, covering Debugging, Failing and flaky tests and Browser testing. It works with Playwright. The repository describes itself as: The open-source AI Operating System.

When your agent uses it

Every Kortix test task
Behavior change
API route change
Browser journey

Example prompts

“/testing”

Requirements

Docker

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

Assign or reuse one stable flow ID.
Describe the complete contract in tests/spec/end-to-end.md.
Implement the contract through HTTP or a real CLI process.
Write each ctx.step() as one natural-language action and result.
Cover authentication, setup, the action, read-back proof, negative paths, and
List every touched API route in meta.routes.
Regenerate tests/spec/routes.generated.json after route changes.

What it can do on your machine

Read from SKILL.md and the folder at commit 0d0613a. 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
- bun
- terraform
- git
- node
- supabase
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use pnpm, git and supabase, 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

Testing loads about 3.6k tokens when it runs, and up to ~14k if it reads all its reference files. Until then it costs about 94 tokens; SKILL.md has 1,850 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~94
When it runs · the whole SKILL.md, loaded when a task matches: ~3.6k
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~14k

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

NoteMentions a .env fileSKILL.md:161

hook encrypts `.env` files and runs `scripts/check-blocked-terms.sh`.

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

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,850 words (~3,599 tokens).

“Use one repository-level command: pnpm test.”

Questions about Testing

What does Testing do?

A skill your agent uses for every Kortix test task, behavior change, bug fix, refactor, API route change, CLI change, SDK change, browser journey, test failure, coverage question, local benchmark…. Testing is an agent skill from kortix-ai/suna. Use for every Kortix test task, behavior change, bug fix, refactor, API route change, CLI change, SDK change, browser journey, test failure, coverage question, local benchmark, or testing infrastructure change.

When should I use Testing?

Testing fits situations like: every Kortix test task; behavior change; API route change; browser journey.

How do I install Testing in Claude Code?

Run `npx skills add kortix-ai/suna --skill testing -a claude-code`. Or copy the skill folder (.agents/skills/testing in kortix-ai/suna) 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 kortix-ai/suna --skill testing -a codex`. Or copy the skill folder (.agents/skills/testing in kortix-ai/suna) 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 kortix-ai/suna --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?

Going by SKILL.md and its folder, Testing needs the command-line tools its instructions call (pnpm, bun, terraform, git, node and supabase). Our summary lists: Docker.

Does Testing access the network?

SKILL.md contains no URLs. Its commands use git, which can reach the network depending on how they are called. This is read from the text; nothing was executed.

Is Testing safe to install?

Our automated static check of SKILL.md found notes only (mentions a .env file), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.

What licence does Testing use?

Testing has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.

How many tokens does Testing use?

About 3.6k tokens (SKILL.md is roughly 14k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 11k tokens, read only when the agent opens those files.

What are the alternatives to Testing?

Skills that share tags, products or a category with Testing: Debugging (idavidov13/agentic-playwright, 223 stars), E2E (sendou-ink/sendou.ink, 297 stars), Debug E2E Test (bitovi/ai-enablement-prompts, 121 stars) and Activitypub Testing (Microck/ordinary-claude-skills, 401 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Testing?

kortix-ai (a GitHub organization) maintains it in kortix-ai/suna, which has 20,256 GitHub stars. The repository holds 20 skills in this directory. The repository was last updated on October 7, 2026.
