integration-builder

integration-builder is a skill for Claude Code, Codex from danielsalles/connector-platform-plugin. It costs 101 tokens per session (1,298 once invoked), scanned A, original, MIT.

A routing guide for connecting an app to third-party online services such as Notion, Slack, Linear, GitHub, or Stripe through an existing connector platform.

In plain words
What is it for?
Adding SaaS integrations and setting up their connection handling for personal projects or apps used by many customers.
Why use it?
It avoids writing each service connection from scratch and explains how connections are associated with either one developer or separate customers in a multi-customer app.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

integration-builder scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 122 lines — stays where its author put it; the contents beside it link to each section on GitHub.

integration-builder

The user is trying to add an integration to the project. The Connector Platform plugin already has the runtime — REST API + MCP server with 100+ pre-built connectors. Don't write integration code from scratch; route to the plugin.

How the platform models the user

Connector Platform has a builder ↔ end_user model. The token in .env.local represents the builder (the dev / company). Each authorization happens for a specific end_user identified by external_ref:

  • Personal mode (solo dev, the default for plugin users): single external_ref="__dev__" end_user. Connections show up immediately on the MCP alias /mcp/<builder_id>/self (auto-resolves to __dev__). The scaffolded handler defaults user_id to __dev__.
  • Multi-tenant (real SaaS with N customers): the dev replaces the hardcoded __dev__ with their session/JWT lookup so each end_user gets their own connections. MCP path becomes /mcp/<builder_id>/<external_ref>.

The dev doesn't have to flip a switch — the platform UI adapts based on the end_user count. You don't need to mention this to the user unless they ask why their connections appear under "Personal mode".

OAuth credentials (shared vs BYO)

Connectors with auth.type === 'oauth2' (github, notion, slack, etc.) default to the platform's shared OAuth app — fine for development, but in production the user should register their own at the provider and configure it at:

<portal>/builder/oauth-apps/<connector_slug>

This gives dedicated rate limits and a consent screen branded as their company instead of "Connector Platform". The /connector add command surfaces this heads-up automatically when scaffolding an OAuth-typed connector.

Decision tree

  1. Detect the integration name from the user's message. Common ones:
    • notion, slack, linear, github, gitlab, stripe, resend, hubspot, airtable, trello, asana, jira, intercom, zendesk, salesforce, mailchimp, sendgrid, dropbox, gmail, google-calendar, google-drive, openai, anthropic, etc.
    • Normalize: lowercase, hyphenate spaces, strip "api" suffix. "Google Calendar" → google-calendar. "Notion API" → notion.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
