When a logic function declares
`workflowActionTriggerSettings.outputSchema`, use it as the step's
initial output schema so downstream steps can pick variables without
first running the Test tab. A successful test run still overrides the
schema with the inferred shape, preserving "test wins" behavior. Falls
back to the existing "Generate Function Output" LINK placeholder when no
schema is declared (custom code steps, older functions).

Adds an optional label field to logic-function input schema properties
(InputSchemaProperty and InputJsonSchema). When set, the workflow
builder renders the label in place of the raw property key for both leaf
inputs and nested sections; when unset, it falls back to the key.
jsonSchemaToInputSchema propagates the label so app authors can declare
it in their JSON schema. Payload paths, the variable picker, and saved
workflow inputs continue to use the property key — labels are
display-only.
## Summary
Replaces the bolted-on `isTool` + `toolInputSchema` fields on
`LogicFunctionManifest` with two distinct, opt-in triggers that align
with the existing `cron` / `databaseEvent` / `httpRoute` trigger
pattern:
- **`toolTriggerSettings`** — exposes the function as an AI tool (chat /
MCP / function calling). Uses standard JSON Schema (the format LLMs
natively understand).
- **`workflowActionTriggerSettings`** — exposes the function as a step
in the visual workflow builder. Uses Twenty's rich `InputSchema` so the
builder can render proper `FieldMetadataType`-aware editors, variable
pickers, labels, and an optional `outputSchema`.
A function can opt into none, one, or both. Each surface gets the schema
format appropriate for it.
### Why
`isTool: true` previously exposed the function as both an AI tool AND a
workflow node, with the same JSON Schema feeding both — but the workflow
builder really wants Twenty's `InputSchema` (with `CURRENCY`,
`RELATION`, `EMAILS`, etc.) and the AI surface really wants standard
JSON Schema. Today the workflow builder hacks around this by treating
JSON Schema as `InputSchema`, which silently breaks for any
non-primitive field type. Splitting the triggers fixes that and lets
each surface evolve independently.
### Migration
- **Fast** instance command adds the two new nullable columns.
- **Slow** instance command backfills `toolTriggerSettings` +
`workflowActionTriggerSettings` from `isTool=true` rows (preserving
today's both-surfaces behaviour) then drops the legacy columns.
### Stacked
Stacked on top of #20181. Merge that first, then this.
## Test plan
- [ ] CI green (oxlint, typecheck, jest, vitest)
- [ ] Run `--include-slow` upgrade against a workspace with existing
`isTool=true` logic functions; verify both new columns populated and old
columns dropped
- [ ] Verify AI chat sees migrated tool functions (Linear create-issue,
Exa search) and can call them with the JSON Schema
- [ ] Add an AI-tool function from the Settings UI (toggles
`toolTriggerSettings`) and verify it shows up in chat
- [ ] Add a workflow-action function from the Settings UI (toggles
`workflowActionTriggerSettings`) and verify it appears in the workflow
node picker
- [ ] In the workflow builder, edit a `LOGIC_FUNCTION` step and verify
input fields render (no more JSON-Schema-as-InputSchema hack)
- [ ] Try defining a function with no triggers in the SDK and verify
`defineLogicFunction` rejects it

**PR 1 of 2.** Follow-up PR ships the Exa app, sets it as a default
pre-installed app, and removes the current `WebSearchTool` /
`WebSearchService` / `ExaDriver`. This PR adds the plumbing; no
user-visible change yet.
## Summary
- Server admins can declare a list of npm app packages to auto-install
on every new workspace and backfill onto existing workspaces via CLI.
- Server-level secrets (like Exa's API key) live on the
`ApplicationRegistration` (one row per server, encrypted) and are
injected into logic function execution env at runtime. No more
per-workspace storage of global secrets.
- A generic `POST /app/billing/charge` endpoint lets app logic functions
emit workspace usage events for metered features. Exa uses it in PR 2;
future apps (call recorder, etc.) reuse it.
- `LogicFunctionToolProvider` tool name prefix changes `logic_function_`
→ `app_`. Shorter, accurate (they come from installed apps).
## What's in this PR
**Logic function executor — server-level variables**
- `LogicFunctionExecutorService.getExecutionEnvVariables` now resolves
env vars in the order: hardcoded defaults →
`ApplicationRegistrationVariable[]` (server-level) →
`ApplicationVariable[]` (workspace-level override). The manifest
`serverVariables` schema has existed; this closes the loop.
**Config**
- `PRE_INSTALLED_APPS` — comma-separated list of npm packages. Default:
empty.
**\`PreInstalledAppsService\`** (new module)
- \`onApplicationBootstrap()\` — fetches each package's manifest from
the app registry CDN, upserts an \`ApplicationRegistration\`, and seeds
declared \`serverVariables\` from matching env vars (e.g.
\`EXA_API_KEY\` env → encrypted registration variable).
- \`installOnWorkspace(workspaceId)\` — installs all pre-installed apps
on a single workspace. Tolerates per-app failures.
**Auto-install on new workspace activation**
- \`WorkspaceService.prefillCreatedWorkspaceRecords\` invokes
\`installOnWorkspace\` after prefilling standard records. Non-blocking
on failure.
**Backfill CLI command**
- \`install-pre-installed-apps\` — iterates active and suspended
workspaces, installs pre-installed apps that aren't yet installed.
Idempotent. Run after changing \`PRE_INSTALLED_APPS\`.
**App billing endpoint**
- \`POST /app/billing/charge\`. Authenticated via \`APPLICATION_ACCESS\`
token (already injected into logic function execution env as
\`DEFAULT_APP_ACCESS_TOKEN\`). Body: \`{ creditsUsedMicro, quantity,
unit, operationType, resourceContext? }\`. Emits \`USAGE_RECORDED\` with
\`applicationId\` as \`resourceId\`. Generic — reusable by any app.
**Tool name prefix**
- \`LogicFunctionToolProvider.buildLogicFunctionToolName\` now produces
\`app_<name>\` instead of \`logic_function_<name>\`. Only affects tools
sourced from logic functions; other tool providers unchanged.
## Stats
- 16 files, +501 / −2
- 7 new files (1 command, 1 service × 2, 1 controller, 1 DTO, 2 modules)
- Typecheck: 7 pre-existing errors, zero new
- Prettier clean
## Behavior deltas
- **\`PRE_INSTALLED_APPS\` default = empty**: existing servers see no
change on merge.
- **\`ApplicationRegistrationVariable\` is now read by the executor**:
apps that were using manifest \`serverVariables\` but expecting them to
be ignored by the executor will now see them injected. No apps ship with
\`isTool: true\` logic functions today, so this is latent — first
consumer is Exa in PR 2.
- **Tool prefix**: currently no logic-function tools are named
\`logic_function_*\` in any production flow. The prefix change affects
only future tools emitted by \`LogicFunctionToolProvider\`.
## Risks
- **CDN unavailability at startup**: if the app registry CDN is down,
\`ensureRegistrationsExist\` logs warnings but doesn't block server
start. Installation on new workspaces during this window will find no
registrations and log a non-blocking error. Backfill command can retry
after CDN recovers.
- **Cold-start overhead**: \`ensureRegistrationsExist\` is called once
per process on bootstrap. Current configurable default is empty, so zero
overhead. When an admin sets \`PRE_INSTALLED_APPS\`, they accept one
HTTP call per package at boot.
- **Server-level variables flow**:
\`ApplicationRegistrationVariable.encryptedValue\` is shared by all
workspaces of a server. Appropriate for a single-tenant Exa key. Not
appropriate for per-tenant keys — those go in workspace-level
\`ApplicationVariable\` and override.
## Test plan
- [ ] \`npx nx typecheck twenty-server\` passes (verified: 7
pre-existing unrelated errors, zero new)
- [ ] Set \`PRE_INSTALLED_APPS=@twenty-apps/hello-world\` (or any real
npm-published app), \`HELLO_WORLD_API_KEY=xxx\`, restart server:
\`ApplicationRegistration\` row is upserted,
\`ApplicationRegistrationVariable\` for HELLO_WORLD_API_KEY is populated
(encrypted).
- [ ] Create a new workspace: the app is auto-installed,
\`ApplicationEntity\` row created, \`LogicFunctionEntity\` rows created.
- [ ] Existing workspace: run \`yarn nx run twenty-server:command
install-pre-installed-apps\`: apps install across all workspaces,
idempotent on re-run.
- [ ] Trigger a logic function that reads
\`process.env.HELLO_WORLD_API_KEY\`: value resolves from the
server-level \`ApplicationRegistrationVariable\`.
- [ ] Log a charge from the handler: \`POST /app/billing/charge\` with
\`Authorization: Bearer \$DEFAULT_APP_ACCESS_TOKEN\` body
\`{creditsUsedMicro: 1000, quantity: 1, unit: "INVOCATION",
operationType: "WEB_SEARCH"}\` → returns \`{success: true}\`,
\`USAGE_RECORDED\` event emitted with correct
\`resourceId=applicationId\`.
- [ ] Tool name generated by \`LogicFunctionToolProvider\` starts with
\`app_\`.
## What's NOT in this PR (PR 2 scope)
- The Exa app itself (\`packages/twenty-apps/...\` directory)
- Removing \`WebSearchTool\`, \`WebSearchService\`, \`ExaDriver\`,
\`web-search\` module
- Removing \`WEB_SEARCH_DRIVER\` config var
- Removing the current \`exa_web_search\` entry in
\`ActionToolProvider\`
- Chat preload list updated to \`app_exa_web_search\`
- Frontend \`getToolDisplayMessage\` branch for \`app_exa_web_search\`
- Setting \`PRE_INSTALLED_APPS\` default to include \`@twenty-apps/exa\`
