Create new skills following the GBrain conformance standard. Generates SKILL.md with frontmatter, Contract, Phases, Output Format, and Anti-Patterns. Checks MECE against existing skills. Updates manifest and resolver.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Skill Creator
## Contract
This skill guarantees:
- New skill follows conformance standard (frontmatter + required sections)
- MECE check: no overlap with existing skills' triggers
- Manifest.json updated
- RESOLVER.md updated with routing entry
- Skill passes conformance tests (`bun test test/skills-conformance.test.ts`)
## Phases
1. **Identify the gap.** What capability is missing? What user intent has no skill?
2. **MECE check.** Review `skills/manifest.json` and `skills/RESOLVER.md`. Does any existing skill already cover this? If so, extend it instead of creating a new one.
3. **Create SKILL.md.** Use this template:
```yaml
---
name: {skill-name}
version: 1.0.0
description: |
{One paragraph describing what the skill does and when to use it.}
triggers:
- "{trigger phrase 1}"
- "{trigger phrase 2}"
tools:
- {tool1}
- {tool2}
mutating: {true|false}

How to install
mdr add garrytan/gbrain/skill-creator@sha256:71d0fd9c45d85f2eThe line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
