The data behind `routineos migrate` is `skills/routineos/registry/migrate-concepts.json` (format `routineos.migrate-concepts.v1`). This page lists every concept and app in it. A test keeps the two in step.

## How a node type is matched

A parser looks a node type up with `migrate.lookup(node_type, tool)`. The tool is `n8n`, `windmill` or `zapier`. Matching is exact first. If nothing matches exactly, the longest entry that ends in `*` and is a prefix of the node type wins. For example `lmChat*` matches every chat-model sub-node. A node type that matches nothing is `step.unknown`. The map is lookup-only, so a wrong node name never matches anything and never breaks a conversion.

## Status

- `mapped`: RoutineOS has a direct equivalent.
- `partial`: it converts, with a stated difference.
- `needs-person`: it converts to a placeholder that a person must finish.
- `unmapped`: reported, with no equivalent.

Every concept with a status other than `mapped` produces an issue in the migration report when it is met.

## Apps

The Claude connector column has two values. `verified` means the app was listed as a claude.ai connector on 2026-10-30, in the session that built this map. `unverified` means it was not on that list. An unverified app falls back to Zapier MCP (connector kind `mcp`) and the report marks it unverified. Neither value says the connector can do everything the source workflow did. Language model providers such as OpenAI are not apps: they map to `step.ai-model` and `step.llm`.

The message column says whether an action on the app counts as sending a message (the pack action kind is `send`). Other write actions are `post`, or `delete` when the step operation is a delete.

## Read operations

An operation counts as a read only when it is in `read_operations`: `get`, `getAll`, `getMany`, `list`, `search`, `read`, `lookup`, `download`, `find`, `select`. A missing or unknown operation counts as a write, so the routine comes out approval-gated.

## Before the gate

Only these step concepts may run before the approval gate, and only when they read: `step.app`, `step.http`, `step.llm`, `step.agent`, `step.transform`, `step.branch`, `step.merge`, `step.loop`, `step.ai-tool`, `step.ai-model`, `step.ai-output-parser`, `step.wait-time` and `step.store`. An app or http step needs explicit read access, a store step needs a read operation, and a write connector or write access always moves the step after the gate. Every other step (code, subworkflow, respond, unknown, approval, memory, vector) runs after the gate, so a routine that has one is approval-gated even when nothing in it is known to write. A step that needs a later step or the gate moves after the gate with it. An agent tool with no app, http, workflow, code or vector mapping (for example a calculator, a search tool or an MCP client) makes its agent step a write, so the agent runs after the gate and the tool raises a needs-person issue.
