## Context The AI Agent workflow node's model dropdown could show a model that was not the one used at run time (e.g. the node displayed "Claude Haiku 4.5" while the run log showed `openai/gpt-5.6-sol`). Root cause: workflow agents were created with `modelId: AUTO_SELECT_SMART_MODEL_ID`. The builder's model `Select` cannot represent that value — auto-select ids are filtered out of the options (`useWorkspaceAiModelAvailability`) and the pinned "default" option remaps its value to the resolved concrete model id (`useAiModelOptions`) — so `Select` silently fell back to `options[0]`, the alphabetically first enabled model. Meanwhile the runtime correctly resolved auto-select to the instance's default smart model. ## What this PR does ### 1. New workflow agents store a concrete model id `WorkflowVersionStepOperationsWorkspaceService` now reads the workspace's `fastModel` setting, expands it through `AiModelRegistryService.getEffectiveModelConfig`, validates it with `validateModelAvailability`, and stores the concrete model id — so the dropdown displays the model that will actually run, and workflow agents default to the cheaper fast tier instead of the smart one. Falls back to `AUTO_SELECT_FAST_MODEL_ID` if the lookup or validation fails (workspace missing, no AI provider configured, model disabled), so node creation never breaks. ### 2. Exclude `search_help_center` and `navigate_app` from workflow agent runs `ActionToolProvider` adds both tools unconditionally, but they only make sense in an interactive chat session (navigation targets the user's browser; help-center search is a support tool). They are now excluded via `WORKFLOW_AGENT_EXCLUDED_TOOL_NAMES` in `AgentAsyncExecutorService`, alongside the existing output-navigation exclusions. Chat agents are unaffected. ## Test coverage - Existing specs for `WorkflowVersionStepOperationsWorkspaceService` and `AgentAsyncExecutorService` updated/passing (new constructor deps mocked). - `nx typecheck twenty-server` and `lint:diff-with-main` pass. <!-- This is an auto-generated description by cubic. --> <a href="https://cubic.dev/pr/twentyhq/twenty/pull/23447?utm_source=github" target="_blank" rel="noopener noreferrer" data-no-image-dialog="true"><picture><source media="(prefers-color-scheme: dark)" srcset="https://www.cubic.dev/buttons/review-in-cubic-dark.svg"><source media="(prefers-color-scheme: light)" srcset="https://www.cubic.dev/buttons/review-in-cubic-light.svg"><img alt="Review in cubic" src="https://www.cubic.dev/buttons/review-in-cubic-dark.svg"></picture></a> <!-- End of auto-generated description by cubic. -->

Why Twenty
Twenty gives technical teams the building blocks for a custom CRM that meets complex business needs and quickly adapts as the business evolves. Twenty is the CRM you build, ship, and version like the rest of your stack.

Installation
Cloud
The fastest way to get started. Sign up at twenty.com and spin up a workspace in under a minute, with no infrastructure to manage and always up to date.
Build an app
Scaffold a new app with the Twenty CLI:
npx create-twenty-app my-app
Define objects, fields, and views as code:
import { defineObject, FieldType } from 'twenty-sdk/define';
export default defineObject({
nameSingular: 'deal',
namePlural: 'deals',
labelSingular: 'Deal',
labelPlural: 'Deals',
fields: [
{ name: 'name', label: 'Name', type: FieldType.TEXT },
{ name: 'amount', label: 'Amount', type: FieldType.CURRENCY },
{ name: 'closeDate', label: 'Close Date', type: FieldType.DATE_TIME },
],
});
Then ship it to your workspace:
npx twenty app:publish --private
See the app development guide for objects, views, agents, and logic functions.
Self-hosting
Run Twenty on your own infrastructure with Docker Compose, or contribute locally via the local setup guide.
Everything you need
Twenty gives you the building blocks of a modern CRM (objects, views, workflows, and agents) and lets you extend them as code. Here's a tour of what's in the box.
