marketplace-create-extension SKILL.md skillA

marketplace-create-extension from dcc-mcp/dcc-mcp-core is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add dcc-mcp/dcc-mcp-core/marketplace-create-extension@git:20261104.1b24f3d

Pins git:20261104.1b24f3d in mdr.lock. Pin the fingerprint instead.

Infrastructure skill — scaffold a new marketplace extension package (SKILL.md + tools.yaml + scripts/) with MIT-0 licensing. Use when creating a publishable marketplace entry for any DCC host. Not for editing existing extensions or driving live DCC scenes — use domain skills for that.

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

# Marketplace Create Extension

## CLI-First Control Path

For marketplace and live-DCC operations, use the `dcc-mcp` skill and
`dcc-mcp-cli` whenever shell access is available. Its consent-gated install and
`dcc-mcp-cli update` contract (check, download, and stage in one step) is the
single source of truth; do not invent a package-local CLI bootstrap path.

Scaffold a new marketplace extension package with the standard dcc-mcp
skill layout and MIT-0 licensing. Follows the same patterns as
`dcc-mcp-skills-creator`.

The scaffold tool creates one Skill. To distribute several generated Skills
together, place them under `skills/` in an Agent Plugins 1.0 package with a root
`plugin.json`; keep them separate when they do not share one release and
uninstall boundary.

## Tools

### `marketplace_create_extension__create`
Scaffold a new extension directory containing SKILL.md (MIT-0), tools.yaml
(with full annotations), and a scripts/ directory with a placeholder action
script that uses `dcc_mcp_core.skills_helper`.

## Prerequisites

- dcc-mcp-core installed
- Write access to the target output directory

## Generated Layout

```
<name>/
├── SKILL.md       # MIT-0 frontmatter + body

How to install

The exact contents, by fingerprint

mdr add dcc-mcp/dcc-mcp-core/marketplace-create-extension@sha256:b2df5e25d4ffc089

The line at the top of this page pins the label git:20261104.1b24f3d, 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.
