What it does

Update is an agent skill from vellum-ai/vellum-assistant. Restart the Vellum assistant and gateway services. Smart branch handling: pulls from main by default, restarts in-place on feature branches, or switches to a specified branch. Pass --pull to force-pull on the current branch.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development. It works with Git. 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.

Workflow steps

8 steps, taken from the first numbered list in SKILL.md.

Ensure Bun is on PATH
Preflight snapshot - capture current state before making changes
Quiesce with vellum sleep - stop assistant and gateway processes. This is directory-agnostic and stops processes globally regardless of CWD
Verify stopped - run vellum ps and confirm no running processes. If vellum ps shows processes still running, run fallback cleanup to…
Smart branch handling - determine what git operations (if any) to perform
Install dependencies - only if git operations ran (dependencies are unlikely to have changed for a local-only restart)
Restart with vellum wake - start assistant and gateway from the current checkout. vellum wake must be run from the checkout directory that…
Verify fresh state - run vellum ps to confirm processes are running

What it can do on your machine

Read from SKILL.md and the folder at commit 844117a. 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
Shell commands in SKILL.md call:
- git
- bun
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
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.

Context cost

Update loads about 1.1k tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 372 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~58
When it runs · the whole SKILL.md, loaded when a task matches: ~1.1k

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.

Update - Restart Vellum (with Smart Branch Handling)

Restart the Vellum assistant and gateway services with branch-aware git behavior.

Arguments

The user may pass $ARGUMENTS to control branch behavior:

Invocation	Behavior
`/update` (no args, on `main`)	Pull latest from `origin/main` (default)
`/update` (no args, on a feature branch)	Skip git ops - restart with the current checkout
`/update <branch>`	Check out that branch, pull if it has a remote
`/update --pull`	Force pull on whatever branch you're currently on

Steps

Ensure Bun is on PATH:
bash
```
export PATH="$HOME/.bun/bin:$PATH"
```
Preflight snapshot - capture current state before making changes:
bash
```
vellum ps
```
Quiesce with vellum sleep - stop assistant and gateway processes. This is directory-agnostic and stops processes globally regardless of CWD:
bash
```
vellum sleep || true
```
Verify stopped - run vellum ps and confirm no running processes. If vellum ps shows processes still running, run fallback cleanup to force-kill them:
bash
```
vellum ps
```
Fallback cleanup if vellum ps confirms processes are still running:
bash
```
pkill -x "vellum-assistant" || true
pkill -f "gateway/src/index" || true
lsof -ti :7830 | xargs kill -9 2>/dev/null || true
lsof -ti :7821 | xargs kill -9 2>/dev/null || true
```
After fallback cleanup, run vellum ps again to confirm all processes are stopped.

Smart branch handling - determine what git operations (if any) to perform:

bash

CURRENT=$(git branch --show-current)
GIT_OPS_RAN=false

Case A - --pull flag: Force pull on the current branch.

bash

if [[ "$ARGUMENTS" == "--pull" ]]; then
  git pull
  GIT_OPS_RAN=true
fi

Case B - Explicit branch name provided: Check out the requested branch, pulling if possible. Before checking out, verify the working tree is clean - if there are uncommitted changes, stop and warn the user rather than silently losing work. Do NOT stash automatically.

bash

if [[ -n "$ARGUMENTS" && "$ARGUMENTS" != "--pull" ]]; then
  if ! git diff --quiet || ! git diff --cached --quiet; then
    echo "ERROR: Uncommitted changes detected. Commit or stash them before switching branches."
    # Stop and report the error to the user. Do not proceed.
  fi
  git checkout "$ARGUMENTS"
  git pull origin "$ARGUMENTS" 2>/dev/null || true
  GIT_OPS_RAN=true
fi

Case C - No args, on main: Pull latest from origin (preserves current default behavior).

bash

if [[ -z "$ARGUMENTS" && "$CURRENT" == "main" ]]; then
  git pull origin main
  GIT_OPS_RAN=true
fi

Case D - No args, on a feature branch: Skip git ops entirely - just restart with the current checkout.

bash

if [[ -z "$ARGUMENTS" && "$CURRENT" != "main" ]]; then
  echo "On branch '$CURRENT' - skipping git pull, restarting with current checkout"
fi

Install dependencies - only if git operations ran (dependencies are unlikely to have changed for a local-only restart):
bash
```
if [[ "$GIT_OPS_RAN" == "true" ]]; then
  cd assistant && bun install && cd ..
  cd gateway && bun install && cd ..
fi
```
Restart with vellum wake - start assistant and gateway from the current checkout. vellum wake must be run from the checkout directory that should supply the new assistant code:
bash
```
vellum wake
```

Verify fresh state - run vellum ps to confirm processes are running:

bash

sleep 5
echo ""
echo "=== Startup Summary ==="
vellum ps
echo "======================="

Report

Tailor the report to what actually happened:

If git pulled (Cases A, B, C): Report what was pulled (new commits), the branch, and whether dependencies were updated.
If restarted in-place (Case D): Report that services were restarted on the current branch with no git changes.
Always include: The startup summary block output (assistant health, gateway health).
