The meta skill. An agent skill from inbrainfun/inbrain.

Works in 8 steps: Should This Be a Skill? → Audit → Write SKILL.md + Code (items 1-2) → …
Tasks that involve Quality gates
SKILL.md covers Contract, The Checklist, Phase 0: Should This Be a Skill? and Phase 1: Audit, plus 10 more sections
Calls jq, bun and gemini; needs OPENAI_API_KEY and ANTHROPIC_API_KEY

What it does

Skillify is an agent skill from inbrainfun/inbrain. The meta skill. Turn any raw feature into a properly-skilled, tested, resolvable unit of agent capability. Cross-modal eval is the recommended Phase 3 quality gate: 3 frontier models from different providers critique the output, you iterate to quality, THEN write tests that lock in the proven-good behavior.

Its SKILL.md is about 2.9k 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 Quality gates and Test generation.

When your agent uses it

Tasks that involve Test generation

Example prompts

“/skillify”

Requirements

A credential in ANTHROPIC_API_KEY

Workflow steps

8 steps, taken from the step headings in SKILL.md.

Should This Be a Skill?
Audit
Write SKILL.md + Code (items 1-2)
Cross-Modal Eval (item 3) — THE QUALITY GATE

Resolver + Check-Resolvable (items 7-9)

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:
- jq
- bun
- gemini
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 these keys or tokens, usually read from environment variables:
- OPENAI_API_KEY
- ANTHROPIC_API_KEY
- GOOGLE_GENERATIVE_AI_API_KEY
- TOGETHER_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Skillify loads about 2.9k tokens when it runs. Until then it costs about 79 tokens; SKILL.md has 1,056 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~79
When it runs · the whole SKILL.md, loaded when a task matches: ~2.9k

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 1,056 words (~2,856 tokens).

“A feature is "properly skilled" when all 11 checklist items pass. Item 3 (cross-modal eval) is informational in v1.1.0 — it does not gate the skillpack-check audit, but a missing or stale receipt is surfaced so the user knows where…”

Can I use Skillify 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 skillify -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/skillify, .gemini/skills/skillify, .github/skills/skillify and .opencode/skills/skillify in your project.

What does Skillify need to run?

Going by SKILL.md and its folder, Skillify needs the command-line tools its instructions call (jq, bun and gemini) and credentials named OPENAI_API_KEY, ANTHROPIC_API_KEY, GOOGLE_GENERATIVE_AI_API_KEY and TOGETHER_API_KEY. Our summary lists: A credential in OPENAI_API_KEY; A credential in ANTHROPIC_API_KEY.
