Create, scaffold, customize, validate, and locally test Qwen Code extensions. Use when the user wants a new Qwen Code extension, needs help choosing an extension template, wants to add QWEN.md context, commands, skills, agents, MCP servers, settings, hooks, channels, or LSP servers, or asks how to link and test an extension locally. Invoke with `/extension-creator` followed by an extension path and optional template name.
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
# Extension Creator
Use this skill to create Qwen Code extensions with the existing extension
scaffold command and bundled templates.
## Workflow
1. Identify the target extension path and requested capabilities.
2. Run `qwen extensions new --help` when you need to confirm the currently
available templates.
3. Choose the setup path:
- If the path does not exist and a template is set, scaffold with
`qwen extensions new "$extension_path" "$template"`.
- If the path does not exist and no template is selected, omit the final
argument.
- If the path exists and has `qwen-extension.json`, use the existing
manifest. Read its `name`; if `qwen extensions list` already shows that
name, treat the task as an iteration on a linked extension and use the
Iterating on a Linked Extension flow instead of linking again unless the
user explicitly wants to re-link it.
- If the path exists but is not an extension, create a minimal
`qwen-extension.json` with `name` set to the directory basename and
`version` set to `"1.0.0"` before customizing.
4. Quote or escape every user-provided shell argument. Choose a final path

How to install
mdr add qwenlm/qwen-code/extension-creator@sha256:dd8584149a186e87The line at the top of this page pins the label git:20260626.5a8918e, 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.
