Template Constructor

End-to-end skill for building, validating, and deploying Machina agent-templates and connectors.

| Reference | Description | |-----------|-------------| | init.md | Scaffold new template project from scratch | | create.md | Generate individual YAML components | | validate.md | Check YAML files against correct patterns | | install.md | Import templates via MCP (local or Git) | | analyze.md | Analyze template structure and dependencies | | trace.md | Trace agent execution chain with variable propagation | | secrets.md | Configure vault secrets for connectors | | api.md | MCP operations for all entities (CRUD, execute, search) | | yaml-reference.md | Complete YAML syntax and patterns | | connectors.md | All available connectors with docs | | frontend-api.md | Next.js frontend API integration |

Schemas

Authoritative field definitions for every Machina entity:

| Schema | Entity | |--------|--------| | agent.md | Agent definition | | connector.md | Connector (PyScript + REST API) | | document.md | Document task type | | mapping.md | Data transformation mapping | | prompt.md | Prompt definition + JSON Schema | | setup.md | _install.yml + _index.yml | | skill.md | SDK skill registration | | workflow.md | Workflow + task types |

Intent Routing

When the user triggers this skill, load the appropriate reference:

| User Says | Reference | |-----------|-----------| | "init template", "scaffold template", "new template project" | init.md | | "create agent", "create workflow", "scaffold YAML" | create.md | | "validate", "check YAML", "verify template" | validate.md | | "install", "import", "deploy template" | install.md | | "analyze", "what's in this template", "overview" | analyze.md | | "trace", "execution chain", "variable flow", "debug agent" | trace.md | | "secrets", "credentials", "configure API key" | secrets.md | | "API", "MCP operations", "search agents", "execute workflow" | api.md | | "YAML syntax", "task types", "expression syntax", "foreach" | yaml-reference.md | | "connectors", "list connectors", "connector docs" | connectors.md | | "frontend", "Next.js", "API integration", "document search" | frontend-api.md | | "report bug", "found issue", "feedback", "suggest improvement" | Show Feedback & Contributing section below |

For YAML field specifics, read the relevant schema from schemas/.

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 (not prompt:) with instruction: (not messages:)
• Connector YAML: Use filetype: (not type:) and filename: (not script:)
• Install order: connectors → documents → prompts → mappings → workflows → agents → skills
