Create, validate, and maintain Frontier skills following the agentskills.io specification. Use when scaffolding a new skill, auditing skill compliance, restructuring for progressive disclosure, or adding scripts/references/assets to an existing skill.
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 > Create, validate, and maintain skills that follow the [agentskills.io](https://agentskills.io) open specification. ## When to Use - Creating a new skill from scratch - Auditing existing skills for spec compliance - Restructuring a skill for progressive disclosure - Adding scripts/, references/, or assets/ to an existing skill ## Knowledge vs Execution Principle Choose the implementation by the kind of work: | Problem Type | Solution | Example | |---|---|---| | **Knowledge** (stable knowledge, changing weekly/monthly) | Skill (Markdown) | Coding standards, triage workflows, deployment conventions | | **Execution** (live API call at runtime) | MCP Server | Query a database, create a GitHub issue, send an email | | **Hybrid** (both) | Skill orchestrating subordinate MCP tools | Skill encodes workflow + judgment; MCP provides API calls | **Standalone Principle**: Every skill SHOULD produce useful output without MCP connections.

How to install
mdr add jnpiyush/agentx/skill-creator@sha256:75f7497b7cf9092cThe 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.
