Skills can run code on your machine — read the SKILL.md first.

What it does

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

  • dif-author-experiment

    Authoring and iterating on dif.sh experiments — drafting frontmatter, choosing variants and weights, declaring audiences, and validating the file. Use whenever the user wants to create, draft, edit, or fix a dif experiment, or mentions A/B test, variant, audience, hypothesis, surface, exclusion group, or the commands dif new, dif validate, or dif build.

  • dif-conclude-experiment

    Concluding a dif.sh experiment — writing a Decision that becomes a useful Learning, archiving the file, and running dif conclude. Use when the user wants to conclude, finish, ship, wrap up, or document the outcome of an experiment, or mentions writing a decision, recording a learning, or the command dif conclude.

  • dif-docs

    Reference for dif.sh — feature flags and A/B experiments stored as Markdown files in the repo and compiled by `dif build` into a typed TypeScript client. Use when adding feature flags, a percentage rollout, or an A/B test to a JavaScript or TypeScript app (Next.js, React, SvelteKit, plain TS), when the user wants flags as code instead of a dashboard, or when the user mentions dif, dif/config.yaml…

  • dif-generate-surfaces

    Generating the initial set of dif.sh surfaces by reading the app's structure and product context. Use when the user wants to set up, scaffold, populate, auto-create, or propose surfaces for a dif project — especially right after `dif init`, when `dif/surfaces/` is empty or sparse, or when `dif new` fails with "surface does not exist". Reads the codebase (routes, pages, README, package.json) plus…

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.
