Install, manage, and share skills across every major coding agent — Claude Code, Cursor, Copilot, and more.

Golang concurrency patterns. Use when writing or reviewing concurrent Go code involving goroutines, channels, select, locks, sync primitives, errgroup, singleflight, worker pools, or fan-out/fan-in pipelines. Also triggers when you detect goroutine leaks, race conditions, channel ownership issues, or need to choose between channels and mutexes.

Lockgate is a cross-platform distributed locking library for Go. Supports distributed locks backed by Kubernetes or HTTP lock server. Supports conventional OS file locks.

Comprehensive guide for Go database access — parameterized queries, struct scanning, NULLable columns, transactions, isolation levels, SELECT FOR UPDATE, connection pool, batch processing, context propagation, and migration tooling. Use when writing, reviewing, or debugging Golang code that interacts with PostgreSQL, MariaDB, MySQL, or SQLite; for database testing; or for questions about database/sql, sqlx, or pgx. Does NOT generate database schemas or migration SQL.

A stage-gated Claude Code skill for academic manuscript writing with discovery, adversarial review, and EN/JP humanizing, packaged as an installable SKILL.md.

A markdown-based build playbook that turns any coding agent into a website build foreman, forcing design decisions and shipping verified sites.

Create or update practical, code-informed plans and trackers. Use ONLY when the user explicitly asks to make or change a plan or tracker. It may also self-invoke while planning a new feature, larger refactor, or other large effort that would benefit from multiple steps or PR splits. Do not self-invoke for routine implementation, small fixes, or ordinary single-step work.

Apply this skill whenever writing, reviewing, or refactoring Laravel PHP code. This includes creating or modifying controllers, models, migrations, form requests, policies, jobs, scheduled commands, service classes, and Eloquent queries. Triggers for N+1 and query performance issues, caching strategies, authorization and security patterns, validation, error handling, queue and job configuration, route definitions, and architectural decisions. Also use for Laravel code reviews and refactoring existing Laravel code to follow best practices. Covers any task involving Laravel backend PHP code patterns.

Designs Command Query Responsibility Segregation (CQRS) and Event Sourcing models with projection rebuilders.

Plans blue-green rollouts, canary deployments, and expand-and-contract schema migrations with zero downtime.
