Klaviyo Observability

What it does

When your agent uses it

• Implementing monitoring for Klaviyo API operations
• Setting up dashboards
• Configuring alerting for Klaviyo integration health
• With phrases like klaviyo monitoring

Example prompts

• “klaviyo monitoring”
• “klaviyo metrics”
• “klaviyo observability”
• “/klaviyo-observability”

Requirements

• Node.js
• Compatibility (from SKILL.md): Designed for Claude Code
• Pre-approved tools (allowed-tools): Read, Write, Edit

Workflow steps

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

1. 1Instrumented API wrapper — write src/klaviyo/instrumented-client.ts with the
2. 2Route every call through instrumentedCall(endpoint, method, () => ...) in
3. 3OpenTelemetry tracing (optional) — add tracedKlaviyoCall() to emit spans
4. 4Structured logging — add a pino logger with an email-redacting serializer.
5. 5Alert rules — drop prometheus/klaviyo-alerts.yml in place for error-rate,
6. 6Metrics endpoint — expose GET /metrics from the shared registry.

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

  Shell commands in SKILL.md call:

  • curl

  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):

  • prometheus.io
  • opentelemetry.io
  • github.com

  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 Claude Code

  From compatibility in the SKILL.md frontmatter.

Context cost

Klaviyo Observability loads about 1.5k tokens when it runs, and up to ~3.5k if it reads all its reference files. Until then it costs about 97 tokens; SKILL.md has 474 words of instructions outside code blocks.

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

~97

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

~1.5k

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.

description

Set up observability for Klaviyo integrations with metrics, traces, and alerts. Use when implementing monitoring for Klaviyo API operations, setting up dashboards, or configuring alerting for Klaviyo integration health. Trigger with phrases like "klaviyo monitoring", "klaviyo metrics", "klaviyo observability", "monitor klaviyo", "klaviyo alerts", "klaviyo tracing".
