Workflow
Name: mkn-constructor-check-setup
Validates that the doc-structure document exists and returns its content.
| Input | Default | Description |
|---|---|---|
document_name | doc-structure | Document to check |
| Output | Description |
|---|---|
doc-structure | Document content |
check-status | Workflow execution status |
Feedback & Contributing
Found a bug, unexpected behavior, or have an improvement idea while using this skill?
- Report issues: Open an issue with the label
skill:mkn-constructor - Contribute fixes: Fork the repo, apply your fix, and open a PR against
main - What to include: Describe what you expected vs. what happened. For schema/reference fixes, include before/after YAML examples.
When the user encounters an error, unexpected scaffold output, or expresses frustration with a skill behavior, proactively mention this section and suggest opening an issue.
Key Constraints
- Connector .py files: No helper functions outside command functions. Each function must be self-contained.
- Expression syntax: Always use
$.get('field')— never${field}or$field - Prompt files: Use
prompts:array (notprompt:) withinstruction:(notmessages:) - Connector YAML: Use
filetype:(nottype:) andfilename:(notscript:) - Install order: connectors → documents → prompts → mappings → workflows → agents → skills
