Agent skills for Claude Code, Cursor & any SKILL.md agent

Claude skills for founders and creators

Two ready-made AI agent skill packs. Give your agent working tools for your back office or your media studio, running on your machine with your own API keys.

What are agent skills?

An agent skill is a small folder an AI coding agent can load on demand. It holds a SKILL.md file, with a short description of when to use it and step-by-step instructions, plus any scripts the agent should run. Claude Code reads every skill's description at start-up; when your request matches one, it pulls in the full instructions and calls the scripts. Cursor and other agents that support the SKILL.md format work the same way.

Skills turn "the agent could probably figure this out" into "the agent does this the same reliable way every time". Each skill in these packs is a SKILL.md plus a small Python command-line tool that calls the provider's official API directly. Nothing is proxied through a third party, and you can read every line.

How to install Claude Code skills

  1. Unzip the pack you downloaded from Gumroad.
  2. Run the installer: ./install.sh copies each skill into ~/.claude/skills. For another agent, set the folder: SKILLS_DIR=/path/to/skills ./install.sh. Existing skills are never overwritten.
  3. Add your keys: copy .env.example to .env and fill in only the services you use. The included QUICKSTART walks through each one.
  4. Ask in plain English. The agent picks the right skills, and you get real results from your own accounts.

Requirements: Python 3.10+. Some skills need their pip requirements or a provider CLI; the film-maker skill needs ffmpeg.

Example: your Monday founder brief

Ask "Give me my Monday founder brief: cash, spend, PRs and today's meetings." The agent reads your Mercury balance, Ramp spend, GitHub review queue, Linear sprint and Google Calendar, then writes a one-page brief and saves it to Google Docs.

"What are we spending on cloud this month, and what's idle?" pulls AWS and Modal costs with a month-end projection and cleanup candidates.

Creator Skill Pack: 8 agent skills for images, video, voice, music and decks

Creator Skill Pack cover

Stop bouncing between five browser tabs to make one post. Ask your agent for an image, a video clip, a soundtrack, a voiceover or a slide deck, and it makes it.

FAQ

What are agent skills?

An agent skill is a folder containing a SKILL.md file (instructions plus a short description) and any scripts it needs. Agents such as Claude Code read the description, and when your request matches, they load the instructions and run the scripts. Skills give an AI agent a repeatable, tested way to do a job instead of improvising each time.

Which agents do these skill packs work with?

Claude Code, Cursor and any other agent that loads SKILL.md skills. The installer targets Claude Code's skills folder by default and accepts a different folder through the SKILLS_DIR variable.

How do I install Claude Code skills?

Unzip the pack and run ./install.sh. It copies each skill into ~/.claude/skills (or $SKILLS_DIR) without overwriting existing folders. Then copy .env.example to .env and add keys only for the services you use.

Are API keys, credits or a hosted service included?

No. You use your own accounts and keys and pay each provider directly, with no markup. The skills run on your machine and call each official API directly, so your data goes only to those services.

What do I need installed?

Python 3.10 or newer. Some skills need a pip install of their requirements or a provider CLI (for example the AWS, GitHub or Modal CLIs, or a Google Cloud OAuth client). The film-maker skill needs ffmpeg.

Do I need every service in the pack?

No. Each skill works on its own, so set up only the ones you use.

Is it safe to let an agent touch my accounts?

The Founder Ops skills require explicit flags for sending, deleting, scaling and stopping, and many commands dry-run first. Credentials stay in local, git-ignored config. You can read every line, since it is plain Python and Markdown.

Can I edit the skills or use them commercially?

Yes, you can modify them. The single-buyer license covers personal or internal business use; resale and redistribution are not allowed. Rights to generated media depend on each provider's terms.

Any limits I should know about?

Spotify's developer terms restrict the Spotify skill to personal, non-commercial use, and newer Spotify apps cannot read BPM or key. YouTube API quotas apply, Gamma's API needs a paid Gamma plan, and you should only clone voices you have consent to use.
