Implements GraphQL APIs in Golang using gqlgen or graphql-go. Apply when building GraphQL servers, designing schemas, writing resolvers, handling subscriptions, or integrating GraphQL with existing Go HTTP services. Also apply when the codebase imports `github.com/99designs/gqlgen` or `github.com/graph-gophers/graphql-go`.
Vercel Connect expert guidance — securely obtain scoped OAuth tokens for third-party services (Slack, GitHub, MCP servers, OAuth, Snowflake) on behalf of apps or users via Vercel OIDC. Use when wiring up third-party API access, connecting to MCP servers, sending Slack messages, accessing GitHub APIs, receiving webhook events from Slack/Linear/GitHub and forwarding them to your agents and apps, or building Eve agent connections.
SAP Converged Cloud Go coding conventions extracted from sapcc/keppel and sapcc/go-bits PR reviews. Enforces architecture patterns, library usage rules, error handling conventions, testing patterns, and anti-over-engineering principles. Use when working in sapcc/* repos, when code imports github.com/sapcc/go-bits, or when targeting SAP CC code review standards. Do NOT use for general Go projects without sapcc dependencies.
Comprehensive news aggregator that fetches, filters, and deeply analyzes real-time content from 8 major sources: Hacker News, GitHub Trending, Product Hunt, 36Kr, Tencent News, WallStreetCN, V2EX, and Weibo. Best for 'daily scans', 'tech news briefings', 'finance updates', and 'deep interpretations' of hot topics.
Package npm/TypeScript/Bun CLI tools for Nix. Use when creating Nix derivations for JavaScript/TypeScript tools from npm registry or GitHub sources, handling pre-built packages or source builds with dependency management.
Systematically find root causes and fix bugs. Use when debugging errors, investigating test failures, reproducing bugs from issue trackers (GitHub, Linear, Jira), or when stuck on a problem after failed fix attempts. Also use when the user says 'debug this', 'why is this failing', 'fix this bug', 'trace this error', or pastes stack traces, error messages, or issue references.
Generate OpenAPI 3.2.0 specifications for third-party APIs (OpenAI, Anthropic, Google, Microsoft, Stripe, GitHub, Slack, AWS, and more)
Build static sites with the Zola generator (Rust-based SSG). Handles project initialization, config.toml configuration, Tera templates, Markdown content (sections via _index.md, pages via *.md), taxonomies, image processing, and deployment. Use for Zola project setup, Tera templating, _index.md structure, RSS/Atom feeds, syntax highlighting, or deployment to Netlify/Cloudflare/GitHub Pages/Vercel/Firebase. Also covers Zola+Astro hybrid architectures.
Conference / internal tech-talk deck — GitHub-dark, JetBrains Mono, terminal code blocks, agenda + Q&A pages. Use for engineering presentations, internal sharing sessions, conference talks, and code-heavy walkthroughs.
Designs and implements state transition analysis systems for tracking time spent in different states. Use when analyzing workflows with state changes (Jira, GitHub PRs, deployments, support tickets, etc.). Covers state machine fundamentals, temporal calculations, bottleneck detection, and business metrics. Trigger keywords: "state analysis", "duration tracking", "workflow metrics", "bottleneck", "cycle time", "state transitions", "time in status", "how long", "state duration", "workflow performance", "state machine", "changelog analysis", "SLA tracking", "process metrics".
Perform read-only reviews of code changes (`git diff`) for quality, architecture compliance, and security (OWASP Top 10) by delegating to Agent tools. Use for self-reviews before committing/creating PRs, or when requesting "review changes" or "code review". Use implement-review-pr for GitHub PR reviews.
Sync all updated skills in ~/.claude/skills/ljg-* to the GitHub repo (ljg-skills). First push to the master branch (in org-mode output style), then switch to the md branch, perform basic markdown conversion, and push. Use when the user says '/ljg-push', 'push skills', 'sync skills', 'sync ljg', or whenever ljg-* skills are updated and need to be shipped. DO NOT use this for pushing non-ljg skills or arbitrary Git repos.
