add-enrichment

name: add-enrichment description: Add a code-defined table enrichment (registry entry) under apps/sim/enrichments/ backed by an ordered provider cascade, ensuring every provider tool it calls has hosted-key support. Use when adding a per-row table enrichment that fills cells via existing Sim tools.

Adding a Table Enrichment

Enrichments are code-defined entries in apps/sim/enrichments/ that run directly per table row (no workflow). Each enrichment declares inputs, outputs, and an ordered list of providers; the cascade runner tries providers in order and the first non-empty result fills the cell. Each provider calls one existing Sim tool via executeTool, which injects the workspace's BYOK key or a hosted key and bills usage automatically.

Because enrichments run on Sim's hosted keys by default, every provider tool you reference must have hosted-key support — otherwise it can only run when the workspace brings its own key. This command makes that check a required step.

Overview

Architecture (what you're plugging into)

• enrichments/types.ts — EnrichmentConfig { id, name, description, icon, inputs, outputs, providers } and EnrichmentProvider { id, label, toolId, buildParams, mapOutput }. Providers are plain data (no @/tools import) so the catalog stays client-safe.
• enrichments/providers.ts — toolProvider(...) (typed passthrough) plus shared input helpers: str(v), normalizeDomain(v), firstNonEmpty(arr), splitName(fullName).
• enrichments/run.ts — the server-only cascade runner. Calls executeTool(provider.toolId, { ...params, _context: { workspaceId } }), accumulates hosted-key cost, returns the first non-empty mapped result. You do not edit this — it works for any registry entry.
• enrichments/registry.ts — ENRICHMENT_REGISTRY / ALL_ENRICHMENTS / getEnrichment. Register new entries here.

Outputs automatically become table columns; billing, the catalog/sidebar UI, the column meta-header icon, and per-row execution all work with no extra wiring.

Step 1: Pick the data-source tool(s)

For each output the enrichment produces, decide which existing tool provides it. Look up the service's API and the tool in apps/sim/tools/{service}/ (e.g. hunter_email_finder, pdl_person_enrich, pdl_company_enrich). Confirm:

• The tool id is registered in apps/sim/tools/registry.ts.
• Its params accept what you can derive from table columns (read the tool's params).
• Its outputs / transformResponse actually expose the field you need (read the real output shape — don't assume).

Order providers cheapest / most-likely-to-hit first; the cascade stops at the first non-empty result. Apollo / LinkedIn are not hosted-safe (ToS) — don't use them.

Step 2: Verify hosted-key support — chain to /add-hosted-key if missing

This is the required gate. For every tool a provider calls, open apps/sim/tools/{service}/{action}.ts and check for a hosting block:

hosting: {
  envKeyPrefix: 'SERVICE_API_KEY',
  apiKeyParam: 'apiKey',
  byokProviderId: 'service',
  pricing: { /* ... */ },
  rateLimit: { /* ... */ },
}

• If hosting is present — good. Note the envKeyPrefix; the deployment needs {PREFIX}_COUNT + {PREFIX}_1..N env vars set for the hosted key to actually resolve at runtime (ops concern, not code). If those env vars aren't set in the target environment, the provider will only run with a workspace BYOK key.
• If hosting is absent — the tool can't use a Sim-provided key, so the enrichment would silently produce blank cells on hosted Sim. Stop and run /add-hosted-key <service> to add hosted-key support to that tool first, then come back. Do this for every provider tool that lacks it.

Why it matters: the cascade runner only bills (and only reads output.cost.total) when executeTool injected a hosted key, which requires the tool's hosting config. No hosting → no hosted key → the enrichment depends entirely on per-workspace BYOK.

Step 3: Write the enrichment definition

Create apps/sim/enrichments/{name}/{name}.ts and a barrel index.ts. Mirror the existing entries (work-email, phone-number, company-domain, company-info).

import { SomeIcon } from 'lucide-react'
import { filterUndefined } from '@sim/utils/object'
import { normalizeDomain, splitName, str, toolProvider } from '@/enrichments/providers'
import type { EnrichmentConfig } from '@/enrichments/types'

export const myEnrichment: EnrichmentConfig = {
  id: 'my-enrichment',
  name: 'My Enrichment',
  description: 'One concise sentence describing what it finds.',
  icon: SomeIcon,
  inputs: [
    // Person enrichments take a single canonical `fullName` (Clay-style);
    // split it with splitName() for tools that need first/last.
    { id: 'fullName', name: 'Full name', type: 'string', required: true },
    { id: 'companyDomain', name: 'Company domain', type: 'string' },
  ],
  outputs: [{ id: 'value', name: 'value', type: 'string' }],
  providers: [
    toolProvider({
      id: 'provider-a',
      label: 'Provider A',
      toolId: 'service_action', // must have `hosting` (Step 2)
      buildParams: (inputs) => {
        // Return null when there aren't enough inputs → cascade skips this provider.
        const name = splitName(inputs.fullName)
        const domain = normalizeDomain(inputs.companyDomain)
        if (!name || !domain) return null
        return { domain, first_name: name.firstName, last_name: name.lastName }
      },
      mapOutput: (output) => {
        // Return { [outputId]: value } on a hit, or null to fall through.
        const value = str(output.value)
        return value ? { value } : null
      },
    }),
    // ...additional fallback providers, in priority order.
  ],
}

// apps/sim/enrichments/{name}/index.ts
export { myEnrichment } from './my-enrichment'

Rules:

• Keep the file client-safe: import only lucide-react, @sim/utils/*, @/enrichments/providers, and the types. Never import @/tools here — the runner does the tool call.
• buildParams returns null when inputs are insufficient (provider skipped). mapOutput returns null/empty for a miss (falls through). Use filterUndefined when assembling optional tool params; coerce numbers explicitly (don't pass '' to number outputs).
• Output ids are the keys mapOutput returns; output names are the default column names (the user can rename them in the config).

Step 4: Register it

In apps/sim/enrichments/registry.ts, import and add the entry (catalog order is registration order):

import { myEnrichment } from '@/enrichments/my-enrichment'

export const ENRICHMENT_REGISTRY: EnrichmentRegistry = {
  // ...existing
  [myEnrichment.id]: myEnrichment,
}

Step 5: Verify

1. bunx tsc --noEmit (from apps/sim, NODE_OPTIONS=--max-old-space-size=8192) and bunx biome check on the changed files.
2. In a table → + New column → Enrichments → pick the new enrichment, map its inputs to columns, name the output column(s), Save. Confirm it appears in the catalog with its icon/description.
3. With hosted keys (or a workspace BYOK key) configured for each provider's service, run a row and confirm the cell fills; the dev-server log shows Enrichment hit { provider }. A row whose providers all miss completes blank; a row where every provider errored shows an error cell.

Checklist

• Each output mapped to a real tool field (verified against the tool's params/outputs)
• Every provider tool has a hosting block — ran /add-hosted-key for any that didn't
• Providers ordered cheapest / most-likely-first; Apollo/LinkedIn not used
• Enrichment file is client-safe (no @/tools import); uses toolProvider + shared helpers
• buildParams returns null on insufficient inputs; mapOutput returns null on a miss
• Registered in enrichments/registry.ts
• tsc + biome clean; created and ran the column end-to-end
