What it does

Sequences is an agent skill from vellum-ai/vellum-assistant. Create and manage automated email drip sequences

Its SKILL.md is about 590 tokens, which your agent loads only when the skill is triggered. The skill folder holds 12 other files (for example `TOOLS.json`, `tools/sequence-analytics.ts` and `tools/sequence-create.ts`). Compatibility notes: Designed for Vellum personal assistants

It sits in Marketing & SEO. 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

  • Marketing & SEO work in your project

Example prompts

  • “/sequences”

Requirements

  • Node.js
  • 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 c92ead1. 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

    Ships script files (TypeScript), which the agent can run.

    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

Sequences loads about 589 tokens when it runs. Until then it costs about 15 tokens; SKILL.md has 281 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~15
When it runs · the whole SKILL.md, loaded when a task matches
~589

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.

You are an email sequence assistant. Use the sequence tools to help users create and manage automated multi-step email drip campaigns.

Capabilities

Sequence Management
  • Create: Build multi-step email sequences with configurable delays, subject lines, body prompts, and per-step approval gates
  • List: View all sequences with status and active enrollment counts
  • Get: Inspect a sequence's full configuration, steps, and enrollment breakdown
  • Update: Modify a sequence's name, description, status, steps, or exit-on-reply behavior
  • Delete: Remove a sequence and cancel all its active enrollments
Enrollment
  • Enroll: Add one or more contacts (by email) to a sequence, with optional personalization context
  • Enrollment List: View enrollments filtered by sequence or status (active, paused, completed, replied, cancelled, failed)
  • Import: Bulk-import contacts from a CSV/TSV file into a sequence (preview mode by default, then confirm to enroll)
Lifecycle Control (via sequence_update)
  • Pause a sequence: Set status: "paused" to halt processing of all enrollments
  • Resume a sequence: Set status: "active" to resume processing on the next scheduler tick
  • Pause/resume/cancel an enrollment: Pass enrollment_id + enrollment_action ("pause", "resume", or "cancel")
Analytics
  • Dashboard: View aggregate metrics across all sequences - total sends, reply rates, completion rates
  • Step Funnel: Drill into a specific sequence to see per-step send counts, reach, and drop-off

Usage Notes

  • Sequences require a messaging channel (e.g. "gmail") to be connected before enrollments can be processed.
  • By default, sequences exit when the contact replies (exit_on_reply: true). Set to false for sequences that should always complete all steps.
  • The sequence_import tool runs in preview mode by default. Call it once to inspect the parsed contacts, then call again with auto_enroll: true to enroll them.
  • Step delays are specified in seconds. Use common conversions: 1 hour = 3600, 1 day = 86400, 1 week = 604800.
