Stack: Next.js 14+ (App Router, RSC, Server Actions, PPR, SSR, SSG, ISR), Turborepo (monorepo, pipelines, remote caching), RemixIcon (3100+ icons). Capabilities: server components, API routes, middleware, caching strategies, build optimization, monorepo management. Actions: create, build, deploy, optimize Next.js apps, setup monorepo, configure caching. Keywords: Next.js, App Router, Server Components, RSC, Server Actions, SSR, SSG, ISR, PPR, Turborepo, monorepo, remote cache, build pipeline, parallel execution, workspace, pnpm, icons. Use when: building Next.js apps, implementing SSR/SSG, setting up monorepos, optimizing build performance, configuring caching strategies, managing shared dependencies.

Provide a pre-commit checklist and staging hygiene (review diffs, stage specific files, avoid common noise like dist/ or .env, and fix mistakes with reset/rm --cached/amend). Use when the user is about to commit, asks for a commit workflow, or needs help cleaning up staged files.

EVE Online ESI API patterns and zkillboard integration. Covers ESI endpoints, authentication, data models, zkillboard RedisQ listener, caching strategies, and EVE-specific IDs (characters, corporations, alliances, ships, systems, regions). Use when working with killmail data, fetching EVE universe info, or implementing ESI calls.

Debugs Buck2 build failures systematically by analyzing error logs, checking common issues (cache, visibility, cycles), and suggesting fixes. Use when builds fail, tests won't run, or Buck2 reports errors.

LLM cost tracking with Langfuse for cached responses. Use when monitoring cache effectiveness, tracking cost savings, or attributing costs to agents in multi-agent systems.

Automatic project context detection with priority-based resolution (Manual setting → Git remote → Subdirectory pattern → Local path → Custom patterns). Auto-activates at start of every CCPM command to ensure correct project context. Supports monorepos with subdirectory detection using glob patterns and priority weighting. Handles ambiguous detection (multiple matches) by asking user to clarify. Caches detection result for command duration (fast reuse). Provides clear error messages with actionable suggestions when no project detected. Displays project context in command headers (e.g., "📋 Project: My Monorepo › frontend"). Supports auto-detection mode (cd = switch) or manual setting (stable context across sessions). Performance: <100ms for auto-detection, 0ms for manual.

Best practices for Gemini API caching strategy including cache versioning, entity-stable keys, and cache busting for WescoBar

Redis semantic caching for LLM applications. Use when implementing vector similarity caching, optimizing LLM costs through cached responses, or building multi-level cache hierarchies.

Use this skill when developing Next.js 16 applications - creating pages, components, layouts, API routes, implementing proxy.ts, adding caching with Cache Components, or refactoring frontend code. This includes working with App Router patterns, Server Components, Server Actions, React 19.2 features, and Tailwind CSS v4.
