Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00078	$0.04814
Opus 5	$0.00039	$0.02407
Sonnet 5	$0.00016	$0.00963
Haiku 4.5	$0.00008	$0.00481

Measured 9d ago against content hash 6ffb016d4db1, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-12, from the pricing page.

Security

Grade A, and why

klaviyo-analyst scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/analyze.py, scripts/klaviyo_client.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Klaviyo Marketing Analyst

Expert-level guidance for Klaviyo email and SMS marketing from the marketing operations and analyst perspective — auditing, building, and optimizing flows, segments, campaigns, and integrations.

For API integration, SDK usage, event tracking implementation, webhooks, and developer patterns, see the klaviyo-developer skill.

Install

Step 1 — Install the skill

git clone https://github.com/thatrebeccarae/claude-marketing.git && cp -r claude-marketing/skills/klaviyo-analyst ~/.claude/skills/

Step 2 — Connect the Klaviyo MCP (recommended)

This skill is designed around Klaviyo's official MCP server. Connect Claude to your Klaviyo account through OAuth — no local API key, no Python install. The setup path depends on which Claude surface you're using.

For Claude Chat or Claude Cowork — use the Connector Directory

Klaviyo is listed in Claude's Connector Directory (announced as part of the expanded Klaviyo + Anthropic integration on 2026-05-07). Setup takes about two minutes:

Open Claude → Settings → Connectors → Browse Connectors
Search for Klaviyo
Click Connect and authenticate

Plan requirement: Connectors are available on Claude Pro, Max, Team, and Enterprise plans. Free plan users will need to use Claude Code or the local install path below.

For Claude Code — register the remote MCP

claude mcp add klaviyo --transport http https://mcp.klaviyo.com/mcp

For audit-only sessions, append ?read-only=true to disable all write tools at the protocol layer:

claude mcp add klaviyo --transport http "https://mcp.klaviyo.com/mcp?read-only=true"

For local install (CI containers, offline development)

claude mcp add klaviyo -e PRIVATE_API_KEY=pk_... -e READ_ONLY=true -- uvx klaviyo-mcp-server@latest

Klaviyo-side requirement: Owner, Admin, or Manager role to authorize the connection.

The MCP exposes 40+ tools across Accounts, Campaigns, Catalogs, Events, Flows, Groups, Profiles, Reporting, Templates, and Translations. See REFERENCE.md for the full tool inventory.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
