What it does
Skill Creator is an agent skill from inbrainfun/inbrain. Create new skills following the Inbrain conformance standard. Generates SKILL.md with frontmatter, Contract, Phases, Output Format, and Anti-Patterns. Checks MECE against existing skills. Updates manifest and resolver.
Its SKILL.md is about 560 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 Agent Workflows, covering Skill authoring and GraphQL.
When your agent uses it
- Tasks that involve Skill authoring
- Tasks that involve GraphQL
Example prompts
- “/skill-creator”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Identify the gap. What capability is missing? What user intent has no skill?
- MECE check. Review skills/manifest.json and skills/RESOLVER.md. Does any existing skill already cover this? If so, extend it instead of…
- Create SKILL.md. Use this template
- Add to manifest. Update skills/manifest.json with name, path, description.
- Add to resolver. Update skills/RESOLVER.md with routing entry in the appropriate category.
- Verify. Run bun test test/skills-conformance.test.ts to confirm the new skill passes.
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:
bun
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
Skill Creator loads about 555 tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 163 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 163 words (~555 tokens).
