What it does
Testing is an agent skill from inbrainfun/inbrain. Skill validation framework PLUS daily test-suite health and regression intelligence. Validates skill conformance (frontmatter, manifest coverage, resolver coverage). Runs the project test suite in tiered phases (unit / evals / integration / system health), classifies failures, and produces a regression-aware report.
Its SKILL.md is about 2k 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 Test generation, LLM evaluation and GraphQL.
When your agent uses it
- Tasks that involve Test generation
- Tasks that involve LLM evaluation
- Tasks that involve GraphQL
Example prompts
- “/testing”
Workflow steps
7 steps, taken from the step headings in SKILL.md.
- Run unit tests
- Run evals (if the project has an evals config)
- Run system health checks
- Git diff analysis (CRITICAL — regression intelligence)
- Classify each failure
- Report format
- Auto-fix protocol
What it can do on your machine
Read from SKILL.md and the folder at commit 5231990. 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:
bungit
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use 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
Testing loads about 2k tokens when it runs. Until then it costs about 81 tokens; SKILL.md has 803 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 803 words (~1,979 tokens).
“This skill has two related but distinct modes:”
- name
- testing
- version
- 1.1.0
- triggers
- validate skills, test skills, skill health check, run conformance tests, run the tests, how are the tests, what's broken, daily test run
- tools

Questions about Testing
What does Testing do?
Skill validation framework PLUS daily test-suite health and regression intelligence. Testing is an agent skill from inbrainfun/inbrain. Skill validation framework PLUS daily test-suite health and regression intelligence.
When should I use Testing?
Testing fits situations like: tasks that involve Test generation; tasks that involve LLM evaluation; tasks that involve GraphQL.
How do I install Testing in Claude Code?
Run `npx skills add inbrainfun/inbrain --skill testing -a claude-code`. Or copy the skill folder (skills/testing in inbrainfun/inbrain) 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 inbrainfun/inbrain --skill testing -a codex`. Or copy the skill folder (skills/testing in inbrainfun/inbrain) 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 inbrainfun/inbrain --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 (bun and git).
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 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 2k tokens (SKILL.md is roughly 7.9k 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: Eval Guide (microsoft/eval-guide, 138 stars), Suite Converter (Margin-Lab/evals, 161 stars), Synthetic Eval Data Generator (ai-evals-course/evals-skills, 1.5k stars) and Axiom Eval Writer (openclaw/clawhub, 9.5k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
Who maintains Testing?
inbrainfun (a GitHub user) maintains it in inbrainfun/inbrain, which has 142 GitHub stars. The repository holds 54 skills in this directory. The repository was last updated on July 17, 2026.
