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.

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:

bash

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

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

bash

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 is listed below with a one-line description; actions that change state carry a [write] or [destructive] tag. Before constructing --data, fetch the action's live schema with oo connector schema to get its authoritative input fields.

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. [write]

Safety

• Untagged actions are reads (get / list / search) — safe to run directly.
• Actions tagged [write] change Plain state — confirm the exact payload and effect with the user before running.
• Actions tagged [destructive] remove or overwrite data — 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):

  bash

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

  powershell

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

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

  bash

  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:

  text

  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.
