What it does

In the author's own words, from each skill's SKILL.md.

  • agent-browser

    This skill should be used when the user needs to navigate websites, interact with web pages, fill forms, take screenshots, test web applications, scrape data, or extract information from web pages. Use for any browser automation task.

  • grill

    Adversarial questioning and collaborative shaping in one skill. Two modes: stress-test (challenge a plan/design until gaps surface) and shape (iterate on requirements and solution options until alignment). Use when user says 'grill me', 'stress-test this', 'challenge this plan', 'shape this', 'let's explore options', or wants to pressure-test any design before committing.

  • handoff

    Compact the current session into a handoff document for another agent or future session to pick up. Captures mission, repo state, role, scope, locked decisions, dispatch sequence, and a pickup checklist. Studio-aware. Use when pausing work, ending a session, switching contexts, or preparing for a fresh agent to continue.

Review before you install

A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
