Create Custom Integration
SkillAI & modelsCreate a new custom integration (API/service wrapper) for the workspace. Guides the user through defining the integration's slug, display name, description, category, and required env keys. Writes .claude/skills/custom-int-{slug}/SKILL.md via POST /api/integrations/custom. Use when the user says 'create an integration', 'add a new integration', 'new custom integration', 'I want to connect X to the workspace', or wants to wire up a new external API/service.

What this skill tells your AI
The instructions your AI receives, as published by evolution-foundation/evo-nexus in .claude/skills/create-integration/SKILL.md and read by ahel’s review.
Guide the user through creating a new custom integration — a wrapper around an external API or service that the workspace's agents can use.
What You're Building
A custom integration is a skill with the custom-int- prefix:
- Lives in
.claude/skills/custom-int-{slug}/SKILL.md - Gitignored (personal to the workspace, not shipped)
- Appears in the dashboard
/integrationspage under the "Custom Integrations" section - Documents the env keys, auth method, and example calls so agents know how to use it
When to use
Use when the user wants to connect a new external API/service that isn't already in the core integration list (Stripe, Omie, Discord, Telegram, etc.). If the integration already exists as core (int-*), don't duplicate — extend or use the existing one.
Step 1: Understand the Integration
Ask the user (short, direct):
- Display name — e.g., "Airtable", "Notion Databases", "Custom CRM". Human-readable.
- Slug — kebab-case ID (e.g.,
airtable). Auto-suggest from display name, let them override. Must be[a-z0-9-]+and not already taken. - Category — one of:
messaging(WhatsApp, Telegram, Discord, email)payments(Stripe, Asaas, Pix, crypto)crm(HubSpot, Salesforce, Pipedrive)social(Instagram, LinkedIn, YouTube, TikTok)productivity(Notion, Airtable, ClickUp, Linear)other
- Description — 1-2 sentences. What does this integration do? What would agents use it for?
- Env keys — what environment variables are needed? Ex:
AIRTABLE_API_KEY,AIRTABLE_BASE_ID. List names only (no values — the user adds those to.envlater). - Auth method (optional, guides the SKILL.md template body) — bearer token, API key in header, OAuth, basic auth, none.
- Base URL (optional) — the API's root URL. Helps generate example calls.
Step 2: Verify slug uniqueness
Check the existing integrations (core + custom) to make sure the slug isn't taken:
from dashboard.backend.sdk_client import evo
existing = evo.get("/api/integrations")
taken = [i["slug"] for i in existing]
if slug in taken or f"int-{slug}" in taken or f"custom-int-{slug}" in taken:
# ask user for a different slug
Also grep the filesystem as a safety check:
ls .claude/skills/int-{slug} .claude/skills/custom-int-{slug} 2>/dev/null
Step 3: Call the API
Use from dashboard.backend.sdk_client import evo — auto-handles URL + auth.
import json
from dashboard.backend.sdk_client import evo
integration = evo.post("/api/integrations/custom", {
"slug": "airtable",
"displayName": "Airtable",
"description": "Query and update Airtable bases. Use when agents need to read/write records in Airtable tables.",
"category": "productivity",
"envKeys": ["AIRTABLE_API_KEY", "AIRTABLE_BASE_ID"],
})
print(json.dumps(integration))
The backend creates .claude/skills/custom-int-{slug}/SKILL.md with a template that documents setup, env keys, and usage. Response shape matches the standard integration entry (with kind: "custom").
Step 4: Add env keys to .env
Remind the user to add the env keys to .env (locally) and, if deploying, to the production .env too:
AIRTABLE_API_KEY=<value>
AIRTABLE_BASE_ID=<value>
The dashboard shows the integration as "Not configured" until the env keys are set.
Step 5: Fill in the SKILL.md body
The backend creates a minimal template. The user (or an agent they delegate to) should flesh out the SKILL.md with:
- Auth details (how the API expects credentials)
- Base URL and common endpoints
- Example calls with
from dashboard.backend.sdk_client import evoOR direct HTTP usingrequests/httpx - Rate limits, quirks, response shapes
Offer to open the file for editing or to delegate to a specialist agent (e.g., @apex-architect for architecture review, @quill-writer for docs polish).
Step 6: Show what happens next
Explain to the user:
- The integration now appears in
/integrations→ "Custom Integrations" section with a[Custom]badge - Agents can discover it via skill search (it's indexed as a skill)
- Edit description/env keys anytime via the pencil icon on the card
- Delete via the trash icon (removes the SKILL.md folder entirely)
- The SKILL.md is gitignored — doesn't leak into the upstream repo
Notes
- If the user just wants to describe a local script (no external API), suggest
create-routineorcreate-commandinstead. - If the integration needs complex state (OAuth tokens, pagination cursors), recommend the user ask
@apex-architectto design the adapter before filling in SKILL.md. - Custom integrations share the same discoverability as core ones — mentioning them in an agent chat (
@agent please call my airtable integration) works once the env is set.
