What the publisher says

From the fnlowl repository's README, as published. We do not edit it. Read it on GitHub

@fnlowl/skills

Agent skills for operating fnlowl (pronounced Funnel Owl — Funnel Intelligence, Agentified!) — lead-capture widgets, the leads they produce, and the mail that follows.

Four skills:

  • fnlowl-capture — build and diagnose widgets, leads, and funnel analytics.
  • fnlowl-follow-up-automation — draft and review delivery, integration handoff, campaigns, and sequences.
  • fnlowl-installation — install embeds on generic sites, WordPress, Shopify, Webflow, and Framer.
  • fnlowl-mcp — connect an agent to the remote MCP surface safely.

Install

npx skills add fnlowl/skills --list
npx skills add fnlowl/skills --global --agent claude-code
npx skills add fnlowl/skills --global --agent claude-code --skill fnlowl-capture
npx skills add fnlowl/skills --global --agent claude-code --skill fnlowl-follow-up-automation
npx skills add fnlowl/skills --global --agent claude-code --skill fnlowl-installation
npx skills add fnlowl/skills --global --agent claude-code --skill fnlowl-mcp

Name your agent with --agent (for example claude-code, codex or cursor). Without it, a non-interactive run (--yes) installs into every agent the installer supports.

Pin a release

Releases are tagged on GitHub. For a stable install, pin a tag instead of the default branch:

npx skills add fnlowl/skills#v0.1.0 --global --agent claude-code

The skills are versioned together as one bundle. A release that renames or removes a skill says so in its notes.

Install as a Claude Code plugin

The repo is also a plugin marketplace, so Claude Code can install it directly:

/plugin marketplace add fnlowl/skills
/plugin install fnlowl@fnlowl-plugins

How to invoke skills

Verify install

Try a task that should trigger one of the skills:

  • "Create a quiz widget for my pricing page."
  • "Why is this widget not converting?"
  • "Draft a three-email nurture sequence for people who finish the quiz."
  • "Add the fnlowl widget to my WordPress site."
  • "Connect Claude to fnlowl and list the tools it can use."

What's included

  • four skills that load when relevant
  • reference files and recipes for the capture and follow-up skills
  • .mcp.json, which points an agent at the hosted MCP server (OAuth sign-in on first use)

It does not ship slash commands or an MCP server of its own; the server runs at https://api.fnlowl.com/v1/mcp.

Use it

The MCP server is at https://api.fnlowl.com/v1/mcp (streamable HTTP, OAuth). .mcp.json in this package points there. Your client opens fnlowl's consent screen the first time: sign in and approve the scopes and website. Tokens are fnla, revocable under Settings → API → Connected apps**; a connector limited to one website is already project-bound, so x-fnlowl-project is ignored.

Claude.ai and ChatGPT work the same way: add the URL as a custom connector (OAuth, leave client id and secret blank).

For scripts and the CLI you can use an API key from Settings → API instead. It starts fnlk, is shown once, and is sent as Authorization: Bearer fnlk....

Scope calls to one project with the x-fnlowl-project header. list_projects returns the ids.

What it will not do

Shortened. The full README is on GitHub.
