skill-creator skillA

skill-creator is agent-read markdown (skill) from jnpiyush/agentx: 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..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

## Knowledge vs Execution Principle

Every agent task is either a **knowledge problem** or an **execution problem**:

| Problem Type | Solution | Example |
|---|---|---|
| **Knowledge** (know something) | Skill (Markdown) | Coding standards, triage workflows, deployment conventions |
| **Execution** (do something) | MCP Server | Query a database, create a GitHub issue, send an email |
| **Hybrid** (know how to do well) | Skill that references MCP tools | Skill encodes workflow + judgment; MCP provides API calls |

**Standalone Principle**: Every skill SHOULD produce useful output without MCP connections.
If disconnecting all MCP servers makes the skill non-functional, the knowledge layer is
not properly separated from the execution layer.

When deciding whether to create a skill or an MCP server, ask:
