Claude Skills

A collection of Claude Code skills.

Installation

First, add the marketplace:

/plugin marketplace add gallop-systems/agent-skills

Then install the skills you want:

/plugin install kysely-postgres@gallop-systems-agent-skills
/plugin install nuxt-nitro-api@gallop-systems-agent-skills
/plugin install nitro-testing@gallop-systems-agent-skills
/plugin install linear@gallop-systems-agent-skills
/plugin install doctl@gallop-systems-agent-skills
/plugin install git-github@gallop-systems-agent-skills
/plugin install copier-template@gallop-systems-agent-skills
/plugin install volt-primevue@gallop-systems-agent-skills
/plugin install vue-nuxt@gallop-systems-agent-skills

Updating

Update a specific skill to the latest version:

/plugin update kysely-postgres@gallop-systems-agent-skills

Auto-updates: Third-party marketplaces don't auto-update by default. To enable:

1. Run /plugin and select Marketplaces
2. Choose gallop-systems-agent-skills
3. Select Enable auto-update

Install as an npm dependency (per-repo)

For JS/TS repos, you can pin the skills to a version via your lockfile instead of the marketplace. Add the package as a dev dependency:

yarn add -D @gallopsystems/agent-skills

On install, a postinstall script symlinks the package's content into the project's .claude/ directory:

• skills — each directory containing a SKILL.md → .claude/skills/<name>
• commands — each .md file under any commands/ directory → .claude/commands/<name>.md

Updating is just a version bump:

yarn up @gallopsystems/agent-skills

These links are generated artifacts (they point into node_modules and are recreated on every install), so ignore them in .gitignore:

.claude/skills
.claude/commands

Notes:

• The script never clobbers a real .claude/skills/<name> or .claude/commands/<name> you authored, and only removes symlinks it created. Run yarn unlink-skills to remove all managed links.
• Works out of the box with Yarn (Classic, or Berry with nodeLinker: node-modules) and npm. pnpm (v10+) blocks dependency build scripts by default — add the package to pnpm.onlyBuiltDependencies for the postinstall to run.
• Yarn Berry with the default PnP linker is not supported (no node_modules folder to link from); use nodeLinker: node-modules.

Available Skills

kysely-postgres

Type-safe Kysely query patterns for PostgreSQL. Automatically activates when working in Node.js/TypeScript projects with Kysely.

Covers:

• Query patterns (SELECT, JOIN, WHERE, aggregations)
• Migrations and recommended column types
• JSON/JSONB and array handling
• String concatenation
• Common pitfalls to avoid

nuxt-nitro-api

Nuxt 4 / Nitro API patterns for building type-safe full-stack applications. Automatically activates when working in Nuxt 4 projects.

Covers:

• Zod validation with h3 (Standard Schema support)
• useFetch vs $fetch vs useAsyncData
• Type inference (don't add manual types!)
• nuxt-auth-utils (OAuth, WebAuthn, middleware)
• Composables vs utils
• SSR + localStorage patterns
• Deep linking (URL params sync)
• Nitro tasks and job queues
• Server-Sent Events (SSE)
• Third-party service integrations

nitro-testing

Test Nitro API handlers with real PostgreSQL using transaction rollback isolation. Each test runs in a transaction that auto-rolls back for complete isolation without cleanup overhead.

Covers:

• Transaction rollback pattern (fast, isolated, real SQL)
• Vitest custom fixtures (factories, db)
• Mock event helpers (mockGet, mockPost, mockPatch, mockDelete)
• Factory pattern for test data creation
• Global stubs for Nuxt auto-imports
• Async/automation testing utilities
• CI/CD setup with GitHub Actions and PostgreSQL

linear

Create, triage, and manage Linear issues following team conventions, with a GraphQL CLI for operations the Linear MCP server doesn't expose.

Covers:

• Issue creation and triage conventions
• Tech-stack labels
• A linear.mjs CLI for GraphQL operations

doctl

Manage DigitalOcean resources with the doctl CLI.

Covers:

• Auth contexts (per-command --context over stateful switching)
• Resolving the current git repo to its DO context + app
• App Platform: deployments, bounded polling, logs and their retention quirks
• App specs: env var/secret round-trips, validation, creating apps
• --format / -o json gotchas
• Managed databases, Spaces keys, droplets, DNS

git-github

Git and GitHub (gh CLI) workflows for agents.
