What it does
Testing is an agent skill from golemcloud/golem. Running and debugging tests in the Golem workspace. Use when writing tests, running specific tests, filtering tests, debugging test failures, or understanding test infrastructure.
Its SKILL.md is about 1.8k 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, covering Failing and flaky tests and Debugging. The repository describes itself as: Golem Cloud is the agent-native platform for building AI agents and distributed applications that never lose state, never duplicate work, and never require you to build…
When your agent uses it
- Running specific tests
- Filtering tests
- Debugging test failures
- Understanding test infrastructure
Example prompts
- “/testing”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Identify which tagged PrecompiledComponent or test component files the selected tests require.
- Build those components first by following their AGENTS.md, or run cargo make build-test-components if a broad rebuild is simpler.
- Only then run the Rust test command.
What it can do on your machine
Read from SKILL.md and the folder at commit 2dea6b9. 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:
cargorg
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):
test-r.vigoo.dev
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 1.8k tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 634 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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 634 words (~1,794 tokens).
“Root-workspace Rust tests use test-r. Each test crate or integration-test entry point using test-r must call test_r::enable!(), and test_r::test must be in lexical scope wherever #[test] is used. Separate workspaces may have their own harness setup.”

Questions about Testing
What does Testing do?
Running and debugging tests in the Golem workspace. An agent skill from golemcloud/golem. Testing is an agent skill from golemcloud/golem. Running and debugging tests in the Golem workspace.
When should I use Testing?
Testing fits situations like: running specific tests; filtering tests; debugging test failures; understanding test infrastructure.
How do I install Testing in Claude Code?
Run `npx skills add golemcloud/golem --skill testing -a claude-code`. Or copy the skill folder (.agents/skills/testing in golemcloud/golem) 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 golemcloud/golem --skill testing -a codex`. Or copy the skill folder (.agents/skills/testing in golemcloud/golem) 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 golemcloud/golem --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 (cargo and rg).
Does Testing access the network?
SKILL.md names 1 domain. As links in the text: test-r.vigoo.dev. This is read from the text; nothing was executed.

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 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 1.8k tokens (SKILL.md is roughly 7.2k 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?
