## Context
Logic functions can declare workflow inputs typed as records or arrays
of records (e.g. the People Data Labs enrichment functions), but the
workflow builder rendered those as a plain text input with a variable
picker, which is not usable.
## What this does
- Adds an `objectUniversalIdentifier` link on input schema properties,
so a record-typed input is tied to a workspace object.
- The SDK build infers it from a
`TwentyRecord<'objectUniversalIdentifier'>` marker type in the handler
signature, reading the object's universal identifier straight from the
source; explicit input schemas can still set the field directly.
- The workflow builder renders these inputs as a single record picker or
a record multi-select with the variable picker on the right. Selected
records are stored as record ids; `TwentyRecord<UID>` is a branded
`string`, so the handler signature reflects that it receives ids (a
bound variable resolves to whatever the referenced step produced).
- The multi-select collapses overflowing chips into a `+N` badge
(reusing `ExpandableList`) and its variable picker offers both record
objects and fields.
- Updates the People Data Labs enrichment inputs as the reference
implementation.

## Summary
Extends the workflow validation layer (introduced in #21422) and adds a
new
"expected output schema" capability for steps whose output structure is
only
known at runtime.
Some workflow steps (HTTP Request, Code, Logic Function, AI Agent
(coming soon), Webhook
trigger) don't have a statically known output shape, so downstream steps
can't
resolve `{{step.x.y}}` variable paths or validate them. This PR lets
users
declare a **sample/expected output** for those steps, derives an output
schema
from it, and uses that schema both to power variable resolution and to
surface
validation issues at build time.
## What's included
### Expected output schema (shared schemas + types)
- New `expectedOutputSchemaShape` reused across the HTTP request, code,
logic
function and AI agent action settings schemas, plus the webhook trigger
schema (`expectedOutputSchema` optional loose object).
- Mirrored on the server-side action/trigger settings types.
### Output schema computation (server)
- `workflow-schema.workspace-service` now computes a step's output
schema from
the user-declared `expectedOutputSchema` sample (via
`getOutputSchemaFromValue`) when no statically computed schema is
available.
### Validation layer (server)
- `STEP_HAS_NO_VARIABLE_REFERENCE` (warning): flags steps of
`VARIABLE_CONSUMING_ACTION_TYPES` (HTTP_REQUEST, CODE, LOGIC_FUNCTION,
SEND_EMAIL, record CRUD) that reference no upstream variable.
- `LOGIC_FUNCTION_OUTPUT_SCHEMA_MISMATCH` /
`AI_AGENT_OUTPUT_SCHEMA_MISMATCH`
(warnings): compare the declared output schema against the expected
sample
using the new shared `getOutputSchemaMismatchIssues` util (missing keys,
leaf/object mismatches, type mismatches).
- Trigger is now validated alongside steps (trigger type requirements +
trigger variable references).
- Validation issues no longer return both `suggestions` and
`availablePaths`
when they are identical (avoids redundant, costly payloads).
### Shared utilities
- New `getOutputSchemaMismatchIssues` (+ tests) in
`twenty-shared/logic-function`.
- Moved `agentResponseSchemaToOutputSchema` from `twenty-front` into
`twenty-shared/ai` so it can be reused on both sides.
### Frontend
- New `WorkflowExpectedOutputBodyInput` component (JSON sample editor
with
validation) used by HTTP request, code, logic function and AI agent step
editors.
- New `resolvePersistedStepOutputSchema` util + `useStepsOutputSchema`
update:
resolves a step's output schema from `outputSchema`, falling back to
`expectedOutputSchema`, with an AI_AGENT default.
- HTTP request / code / logic function editors persist
`expectedOutputSchema`
and derive `outputSchema` from it.
- Webhook trigger default settings include `expectedOutputSchema`.
BONUS : iterator loop validation

## Problem
`any[]` type prevented value input:
<img width="544" height="349" alt="Screenshot 2026-06-01 at 14 08 47"
src="https://github.com/user-attachments/assets/956238d0-6fea-4be1-b75a-ab0e6e6424ac"
/>
In the workflow Code action (and the Logic Function action), parameters
typed as any[], string[], etc. rendered as an empty grey box instead of
an "Enter value" text input. After any debounced save, even a properly
initialised array field would also collapse into an empty container.
The Array<T> / ReadonlyArray<T> generic form fell through to a generic
text input by accident (which "looked" right, but for the wrong reason —
no schema info downstream).
## Root causes
Three places treated arrays as plain objects via @sniptt/guards'
isObject (which is true for arrays):
1. WorkflowEditActionCodeFields.tsx — arrays went into the nested-fields
branch; Object.entries([]) is empty → empty container, no placeholder.
2. mergeDefaultFunctionInputAndFunctionInput.ts — recursed into arrays
during merge, turning [] into {}. Triggered on every debounced save, so
the bug surfaced after any edit.
3. get-function-input-schema.ts — only handled T[]
(SyntaxKind.ArrayType); Array<T> (SyntaxKind.TypeReference) was
unrecognised, so the form lost any item-type info.
## Summary
- Fixes a regression from #20208 where creating a new CODE workflow step
shows no input fields
- The split-triggers PR removed `SEED_LOGIC_FUNCTION_INPUT_SCHEMA` and
replaced `toolInputSchema` with `workflowActionTriggerSettings`, but
`CodeStepBuildService.createCodeStepLogicFunction` was not updated to
pass the seed schema — causing `logicFunctionInput` to default to `{}`
and no fields to render
- Adds `SEED_WORKFLOW_ACTION_TRIGGER_SETTINGS` constant (matching the
seed template's `{ a: string, b: number }` params) and passes it when
creating the seed logic function
## Test plan
- [x] Unit test updated to assert `logicFunctionInput` contains `{ a:
null, b: null }` on code step creation
- [x] Create a new CODE step in the workflow builder and verify input
fields `a` and `b` appear immediately

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\`
