Plain

Plain (plain.com). Use this skill for ANY Plain request — reading, creating, and updating data. Whenever a task involves Plain, use this skill instead of calling the API directly.

Operate Plain through your OOMOL-connected account. This skill calls the plain connector with the oo CLI; OOMOL injects credentials server-side, so you never handle raw tokens.

Category: Communication, Productivity. Exposes 4 action(s).

Running an action

Assume the user has already installed the oo CLI, signed in, and connected Plain. Do not run oo auth login or open the connection URL proactively — just run the action. Fall back to First-time setup only when a command actually fails with an auth or connection error.

1. Inspect the contract to get the authoritative input/output schema before building a payload:

oo connector schema "plain" --action "<action_name>"

2. Run the action with a JSON payload that matches the input schema:

oo connector run "plain" --action "<action_name>" --data '<json>' --json

• --data takes a JSON object string or @path/to/file.json; omit it to send {}.
• The response is { "data": ..., "meta": { "executionId": "..." } }; the execution id lives under meta.executionId.

Each action below links to a reference file with its purpose and exact commands. Read the linked file, then fetch the live schema with oo connector schema before constructing --data.

Available actions

• get_customer_by_email — Fetch one Plain customer by exact email address.
• get_customer_by_external_id — Fetch one Plain customer by exact external ID.
• search_customers — Search Plain customers with one human-oriented term across full name, short name, email, and external ID.
• upsert_customer — Create or update one Plain customer using exactly one identifier plus create and update payloads.

Safety

• Read actions (get / list / search) are safe to run directly.
• Create, update, send, or post actions change Plain state — confirm the exact payload and effect with the user before running.
• Delete or remove actions are destructive — always confirm the target and get explicit approval first.

First-time setup

These are one-time steps — do not repeat them on every call. Run a step only when a command fails for the matching reason.

• oo: command not found — install the oo CLI (other platforms: https://cli.oomol.com/install-guide.md):

  curl -fsSL https://cli.oomol.com/install.sh | bash    # macOS / Linux
  

  irm https://cli.oomol.com/install.ps1 | iex           # Windows PowerShell
  

• Not signed in / authentication error — sign in to your OOMOL account once:

  oo auth login
  

• scope_missing / credential_expired / app_not_ready / app_not_found — Plain is not connected, or the connection expired or lacks a scope. Connect once (auth type: API key) at:

  https://console.oomol.com/app-connections?provider=plain
  

• HTTP 402 / OOMOL_INSUFFICIENT_CREDIT — billing stop. Recharge at https://console.oomol.com/billing/token-recharge before retrying.
