Klaviyo Data Handling

What it does

When your agent uses it

• Handling profile data
• Implementing right-to-deletion
• Configuring data retention
• Ensuring compliance with privacy regulations

Example prompts

• “klaviyo data”
• “klaviyo PII”
• “klaviyo GDPR”
• “/klaviyo-data-handling”

Requirements

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

Workflow steps

5 steps, taken from the step headings in SKILL.md.

1. 1GDPR Profile Deletion (Right to Erasure)
2. 2Data Subject Access Request (DSAR)
3. 3PII Detection and Redaction in Logs
4. 4Consent Management
5. 5Audit Logging

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

  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 typescript).

  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 Data Handling loads about 1.8k tokens when it runs, and up to ~3.5k if it reads all its reference files. Until then it costs about 107 tokens; SKILL.md has 594 words of instructions outside code blocks.

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

~107

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

~1.8k

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

~3.5k

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.
