AI skill pack — reusable SKILL.md definitions for coding agents.

Skills

Nix

Skill	Description
`nix-bun`	Bun + Nix via bun2nix — bun.nix dependency workflow, the `bun --compile` pitfall, CI drift check
`nix-ci`	CI setup for GitHub repos — GitHub Actions or Vira
`nix-for-dev`	Fast `nix develop` setup — zero-inputs `flake.nix`, npins, sub-flakes for non-user-facing Nix
`nix-haskell`	Haskell projects with haskell-flake: dependencies, settings, devShell, autoWire
`nix-health`	Diagnosing Nix installation health — flakes, version, caches, max-jobs, direnv, and shell config
`nix-justfile`	Conventions for writing justfile recipes in Nix-based projects
`nix-oss-cache`	Set up a GitHub repo to push Nix builds to Juspay's shared OSS Attic cache (`cache.nixos.asia/oss`)
`nix-perf`	Diagnosing slow first-fetch (`direnv allow` / `nix flake archive`) — lockfile inspection, `follows` patterns, and cold-fetch measurement
`nix-playwright`	Run an existing Playwright e2e suite locally on NixOS via `tests/shell.nix` + justfile
`nix-rust-leptos`	Conventions for building Leptos CSR apps with Nix (crane + Trunk)
`nix-typescript`	pnpm + Nix build conventions — fetchPnpmDeps hash management and dependency workflow

Writing

Skill	Description
`pg`	Write essays, articles, and blog posts in Paul Graham's voice — plain, spoken prose that reasons out loud, not AI filler
`programming-essay`	Write programming essays in the voice of the canon — Spolsky, Yegge, Graham, Nystrom, Brooks

Tooling

Skill	Description
`cargo-watch`	Run cargo-watch in the background for continuous clippy feedback during code editing
`vhs`	Deterministic terminal demo screencasts with VHS and wait patterns

Usage

This repository is an Agent Plugins package (spec 1.0.0). The repo root carries plugin.json and each skills/<name>/SKILL.md is a skill, so any client that implements the standard can load this repo as a plugin — no client-specific wiring needed.

It is also a plugin marketplace: the catalogs at .omp-plugin/marketplace.json and .claude-plugin/marketplace.json list the repo root as the juspay-skills plugin.

With Oh My Pi (omp)

/marketplace add juspay/skills
/marketplace install juspay-skills@juspay

Or from the command line:

omp plugin marketplace add juspay/skills
omp plugin install juspay-skills@juspay

To use a local checkout without installing, point omp at it directly:

omp -e /path/to/skills

Every skill in this repo becomes available as /skill:<name>. Run /reload-plugins to pick them up without restarting the session.

With Claude Code

/plugin marketplace add juspay/skills
/plugin install juspay-skills@juspay

With any other Agent Plugins client

Point the client at a checkout of this repo (or install it from the marketplace catalog); it will find plugin.json at the root and load every skill under skills/.

With APM (Claude Code, Cursor, Copilot)

Install individual skills using APM virtual subdirectory references:

# apm.yml
dependencies:
  apm:
    - juspay/skills/skills/nix-for-dev
    - juspay/skills/skills/nix-haskell
    - juspay/skills/skills/nix-ci

apm install

Each skill is a standalone package — pick only what your project needs. See Kolu's apm.yml for an example.

With OpenCode

juspay/AI bundles these skills into its oneclick OpenCode packages via APM. Run nix run github:juspay/AI to get OpenCode with all skills pre-configured.

Manual

Copy any skills/<name>/SKILL.md into your agent's skills directory (e.g., .claude/skills/<name>/SKILL.md for Claude Code).
