Klaviyo Core Workflow A

What it does

When your agent uses it

• Creating/updating profiles
• Subscribing contacts
• Syncing customer data to Klaviyo for email/SMS marketing
• With phrases like klaviyo profiles

Example prompts

• “klaviyo profiles”
• “klaviyo lists”
• “klaviyo subscribe”
• “/klaviyo-core-workflow-a”

Requirements

• Node.js
• A credential in KLAVIYO_PRIVATE_KEY
• Compatibility (from SKILL.md): Designed for Claude Code
• Pre-approved tools (allowed-tools): Read, Write, Edit, Bash(npm:*), Grep

Workflow steps

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

1. 1Create or update a profile — prefer createOrUpdateProfile (upsert) over createProfile so re-syncs don't 409 on an existing email.
2. 2Create a list — listsApi.createList(...) returns the listId you use downstream; getLists() enumerates existing lists.
3. 3Add profiles to a list — createListRelationships adds membership only; it does NOT grant marketing consent.
4. 4Subscribe profiles — subscribeProfiles records email/SMS marketing consent with a consentTimestamp. This is the correct way to create real…
5. 5Query profiles with filters — getProfiles({ filter, sort }) supports equals, greater-than, and contains for segmentation.
6. 6Bulk import — batch upserts in groups of 100 to stay within rate limits.

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves these tools, so the agent can use them without asking each time:

  • Read
  • Write
  • Edit
  • Bash(npm:*)
  • Grep

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • npm

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

• Network

  Links to these hosts (documentation or services it may open):

  • developers.klaviyo.com

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

• Credentials

  Names these keys or tokens, usually read from environment variables:

  • KLAVIYO_PRIVATE_KEY

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

• Compatibility

  Designed for Claude Code

  From compatibility in the SKILL.md frontmatter.

Context cost

Klaviyo Core Workflow A loads about 1.3k tokens when it runs, and up to ~3.3k if it reads all its reference files. Until then it costs about 91 tokens; SKILL.md has 424 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~91

When it runs · the whole SKILL.md, loaded when a task matches

~1.3k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~3.3k

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

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.
