What it does

Conversation Launcher is an agent skill from vellum-ai/vellum-assistant. Offer the user several spin-off conversations as clickable buttons on a single persistent card. Each click spawns a fresh seeded conversation in the sidebar; the user keeps their place in the current conversation. Use when you want to branch into N focused threads (research directions, draft choices, pending replies, triage of N items) without losing the current context. Not for single-destination pivots — just reply inline.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Designed for Vellum personal assistants

The repository describes itself as: An AI Assistant that’s easy to setup, does your work 24/7, knows your preferences and gets better over time. The licence is MIT.

When your agent uses it

  • You want to branch into N focused threads (research directions
  • Pending replies
  • Triage of N items) without losing the current context

Example prompts

  • “/conversation-launcher”

Requirements

  • Compatibility (from SKILL.md): Designed for Vellum personal assistants

What it can do on your machine

Read from SKILL.md and the folder at commit 33cc983. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are json).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Designed for Vellum personal assistants

    From compatibility in the SKILL.md frontmatter.

Context cost

Conversation Launcher loads about 1.2k tokens when it runs. Until then it costs about 113 tokens; SKILL.md has 514 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~113
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

🧭

Use this skill when you want to offer the user several spin-off conversations from the current one. You render one persistent card. Each button on the card spawns its own seeded conversation in the sidebar. The user can click multiple buttons without losing their place — the origin conversation (this one) keeps focus.

When this fits

  • Research branches — "here are three angles to pursue"
  • Draft choices — "here are the reply drafts I could write"
  • Triaging N items — "here are the five threads with pending replies"
  • Pending-reply fan-out — each sender gets their own drafting conversation

When this does NOT fit

  • Single-destination pivots — if there's one obvious next conversation, just reply inline or navigate there directly. One button is not a menu.
  • Options that share context and should stay in one thread — keep them here.
  • Inline Q&A the user can skim in place — answer; don't fan out.

How to render

Emit exactly one ui_show call with a card shaped like this, then end your turn:

json
{
  "surface_type": "card",
  "display": "inline",
  "persistent": true,
  "await_action": false,
  "data": {
    "title": "<framing headline>",
    "body": "<one short sentence framing the choice>"
  },
  "actions": [
    {
      "id": "opt-1",
      "label": "<short button label>",
      "style": "primary",
      "data": {
        "_action": "launch_conversation",
        "title": "<short conversation title>",
        "seedPrompt": "<full first-user-message seed>",
        "anchorMessageId": "<optional anchor message id from this conversation>"
      }
    },
    {
      "id": "opt-2",
      "label": "<short button label>",
      "style": "secondary",
      "data": {
        "_action": "launch_conversation",
        "title": "<short conversation title>",
        "seedPrompt": "<full first-user-message seed>"
      }
    }
  ]
}

Field notes:

  • persistent: true keeps the card visible after a click so the user can fire more buttons.
  • await_action: false lets the turn end without reserving the interactive-surface slot — the launcher dispatches its action directly, so blocking other surfaces is unnecessary.
  • Each action's data must contain _action: "launch_conversation", title, and seedPrompt. anchorMessageId is optional — include it when the spawned conversation should thread off a specific message in this one.
  • label is the button text (short, ≤ 4 words, ≤ 30 chars). title is the new conversation's sidebar name (3–5 words, specific not generic). seedPrompt is the first user message of the new conversation — written in first-person as if the user typed it, with enough context that the new conversation can pick up without re-asking.
  • Use style: "primary" for the recommended option (at most one), style: "secondary" for the rest.

Do nothing else

After rendering the card, end your turn. The click pipeline handles everything:

  • Do NOT run a follow-up step, issue any HTTP request, or write any file.
  • Do NOT send a chat message after the card. The card is the response.
  • Do NOT re-render the card on each click — it stays visible.

UX contract the client enforces

  • The card stays open and clickable for the lifetime of the live conversation — multiple buttons can be fired in succession without losing the user's place. If the conversation is closed and reopened later from history, the restored card reverts to single-click behavior (history rehydration drops the persistent flag — out of scope for this skill).
  • Each action.id fires at most once per card lifetime; sibling actions remain clickable.
  • Each spawned conversation inherits this conversation's guardian / trust context automatically.
  • Sidebar focus stays on this conversation. The user sees new entries appear and can navigate in at their pace.

Authoring tips

  • Don't invent options. Only surface branches the user has actually discussed or implied.
  • 2–5 buttons is the sweet spot. One option? Just reply inline. More than five? Trim or group.
  • Keep the card body to one sentence. The buttons carry the payload; the body just frames the choice.
  • Conversation titles should be highly concise, context-specific, and 3–5 words.
