# What the verified UI supports

Each part of the Slack client the verified UI draws, the Web API methods it calls and what it leaves out.

This page lists every part of the Slack client the [verified UI](https://www.rystic.ai/docs/simulators/slack/features/verified-ui.md) draws. A test checks each **Works** row through the Web API, so write tasks against those rows; the Web API column names the methods each one calls, which a grader reads.

|---|---|---|
| shell | app load → current actor in the rail avatar and actor switch | `auth.test` |
| shell | workspace name and icon at the top of the sidebar | `team.info` |
| shell | server holds the Socket Mode link; each event refreshes the open page | `apps.connections.open` |

**Gap**: the UI shows it, and it does not yet work as it does in the real service.

| Area | Feature | Why |
|---|---|---|
| conversations | conversation tabs: one per canvas conversations.info lists in properties.tabs, titled by the canvas → the canvas in the tab, with its outline and ⋮ | The simulator's conversations.canvases.create adds no canvas tab to conversations.info's properties.tabs, so a channel's canvas shows only in the page that made it. |
| people & status | Edit profile → Upload photo (multipart image) | The simulator's users.setPhoto refuses a multipart/form-data body with invalid_form_data and an image sent as text with no_image, while Slack takes the image as a multipart file, so the upload shows that error. |
| search & navigation | rail Files → the Files sidebar → Canvases: + New, a search box and All / Created by you / Shared with you over the viewer's canvases (files.list types=canvases), each opening its canvas, a row's ⋮ → Delete canvas | The simulator's files.list lists no canvas that canvases.create made, so the browser shows none. |
| apps & views | a button press → the app opens a modal → its title, blocks, text inputs, Cancel and Submit | Waits on the simulator: views.open does not yet take the trigger_id of a press, and the simulator does not yet tell a person's client that an app opened a modal for them. |
| apps & views | modal → Submit → views.submit with the text inputs' state; an empty or clear ack closes it, and an input left empty when required, malformed (email, URL, number) or outside its length or value limits says so under it first | Waits on the simulator: views.open does not yet take the trigger_id of a press, and the simulator does not yet tell a person's client that an app opened a modal for them. |
| apps & views | modal → Submit → an errors ack → each message under its input block, the modal open with what was typed | Waits on the simulator: views.open does not yet take the trigger_id of a press, and the simulator does not yet tell a person's client that an app opened a modal for them. |
| apps & views | modal → Submit → an update ack → the modal swaps to the ack's view, keeping what was typed into inputs it keeps | Waits on the simulator: views.open does not yet take the trigger_id of a press, and the simulator does not yet tell a person's client that an app opened a modal for them. |
| apps & views | modal → Submit the app doesn't ack → Slack's generic error at the top of the modal, the inputs as typed | Waits on the simulator: views.open does not yet take the trigger_id of a press, and the simulator does not yet tell a person's client that an app opened a modal for them. |
| sidebar | 'you' on your own DM, 'invited you' on a DM someone else opened | The simulator's conversations.info on an IM names no creator, as Slack's documented IM object names none, so the "invited you" suffix has nothing to read. |
| canvases & lists | the canvas view's header: the canvas's title | The simulator's files.info returns file_not_found for a canvas, so the header says its title can't be read. |
| canvases & lists | rail Files → the Files sidebar → Lists: + New, a search box and All / Created by you / Shared with you over the viewer's Lists (files.list types=lists), each opening its List | The simulator's files.list lists no List that slackLists.create made, so the browser shows none. |
| canvases & lists | List header ⋯ → Download as CSV | The simulator's slackLists.download.get returns a link the simulator doesn't serve, so the download says it's unavailable. |

**Out**: the UI leaves it out on purpose.

| Area | Feature | Why |
|---|---|---|
| shell | `api.test` | Connectivity check; no screen in the Slack client calls it. |
| shell | rail Agents & tools | Disabled, says why on click: the simulator serves no app, agent or workflow directory. |
| shell | rail Admin | Disabled, says why on click: needs admin.*, which the simulator doesn't serve. |
| shell | rail foot moon: Turn on focus mode | Disabled, says why on click: the simulator models no focus mode (no users.prefs or dnd.setSnooze). Real Slack's moon is focus mode, not a theme switch. |
| shell | top bar: Chat with Slackbot AI, right of Search | Disabled, says why on click: the simulator serves no Slack AI. |
| shell | top bar: Help (?) at the right end | Disabled, says why on click: Slack's help center and feedback aren't part of the simulator. |
| shell | rail foot Create new (+) → Huddle | Disabled, says why on click: the simulator serves no huddle API. |
| shell | rail foot Create new (+) → Workflow | Disabled, says why on click: the simulator serves no workflows. |
| shell | rail foot Create new (+) → Invite people | Disabled, says why on click: needs admin.users.invite, which the simulator doesn't serve. |
| messages | `chat.postEphemeral` | No client control sends one; showing a received one needs a client delivery the simulator keeps on the control plane. |
| messages | `chat.startStream` | Bot token only; the client never starts a stream, and renders a streamed message as any other. |
| messages | `chat.appendStream` | Bot token only; no client control. |
| messages | `chat.stopStream` | Bot token only; no client control. |
| messages | composer toolbar: More options (…), after Mention someone | Disabled, says why on click: shortcuts and workflows come from apps, which the simulator doesn't serve. |
| messages | message hover → Forward message…, between Reply in thread and Save for later | Disabled, says why on click: Slack forwards through a client method the Web API doesn't publish; chat.postMessage with a permalink would post a different message than a forward. |
| reactions | `reactions.list` | No Slack client screen lists the items a person reacted to. |
| threads | thread pane header: Summarize thread | Disabled, says why on click: the simulator serves no Slack AI. |
| threads | thread pane header ⋮ → Get notified about new replies | Disabled, says why on click: needs subscriptions.thread.*, which the simulator doesn't serve. |
| threads | thread pane header ⋮ → Mark unread | Disabled, says why on click: a thread's read mark needs subscriptions.thread.*, which the simulator doesn't serve; conversations.mark would move the channel's read mark instead. |
| conversations | channel header: Start huddle (headphones) and More Huddles options (chevron) | Disabled, says why on click: the simulator serves no huddle API. |
| conversations | channel header bell (Edit notifications) and header ⋮ → Edit notifications | Disabled, says why on click: needs users.prefs, which the simulator doesn't serve. |
| conversations | channel header ⋮ → Open in new window | Disabled, says why on click: this client is a single window. |
| conversations | conversation tabs: + → File, canvas, or list (New) | Disabled, says why on click: Slack adds the tab with conversations.addTab, which the simulator doesn't serve. |
| conversations | conversation tabs: + → Workflow | Disabled, says why on click: the simulator serves no workflows. |
| conversations | conversation tabs: + → Folder | Disabled, says why on click: bookmark folders aren't part of the simulator. |
| conversations | conversation tabs: + → Add template to channel | Disabled, says why on click: the simulator serves no channel templates. |
| conversations | conversation tabs: + → Edit tabs | Disabled, says why on click: no write reorders or removes a channel's tabs. |
| files | `upload/v1/{ticket} (PUT)` | The client POSTs the bytes; PUT is the same upload over another verb. |
| files | rail Files → the Files sidebar → Deleted | Disabled, says why on click: the simulator serves no read of deleted canvases and Lists. |
| files | rail Files → the Files sidebar → Starred | Disabled, says why on click: needs stars.list, which the simulator doesn't serve. |
| files | rail Files → the Files sidebar's More options | Disabled, says why on click: the Files sidebar's settings aren't part of the simulator. |
| files | the Canvases and Lists pages' Templates row and See all | Not drawn: the simulator serves no canvas or List templates. |
| people & status | `users.identity` | Sign in with Slack identity endpoint; the client has no screen for it. |
| scheduling | `reminders.info` | Later draws each reminder from reminders.list; no screen reads one reminder alone. |
| search & navigation | Later → Archived tab | Disabled, says why on click: archiving a Later item is Slack's saved.* state, which the simulator doesn't serve. |
| search & navigation | Later header → Filter | Disabled, says why on click: Later's filters read Slack's saved.* state, which the simulator doesn't serve. |
| search & navigation | Huddles | No huddle API in the simulator. |
| search & navigation | `search.all` | The results view asks search.messages and search.files, one per tab, so each tab pages on its own; search.all returns the same two lists and no other screen needs it. |
