Static-first Next.js 16 architecture patterns: cached shells with dynamic slots, provider islands, 'use cache' boundaries, and link preloading strategy. Use when building or refactoring Next.js routes to maximize static rendering, implementing 'use cache' with dynamic personalization, splitting entry vs static renderers, scoping client providers, or tuning prefetch behavior. Triggers on 'static shell', 'use cache pattern', 'dynamic slots', 'provider island', 'prefetch strategy', 'static first', 'cache boundary', 'route goes dynamic unexpectedly', or any Next.js architecture work involving mixed static/dynamic rendering.

Set up self-hosted Inngest on macOS as a durable background task manager for AI agents. Interactive Q&A to match intent — from Docker one-liner to full k8s deployment with persistent state. Use when: 'set up inngest', 'background tasks', 'durable workflows', 'self-host inngest', 'event-driven functions', 'cron jobs', or any request for a local workflow engine.

Design and build agent-first CLIs with HATEOAS JSON responses, context-protecting output, and self-documenting command trees. Use when creating new CLI tools, adding commands to existing CLIs (joelclaw, slog), or reviewing CLI design for agent-friendliness. Triggers on 'build a CLI', 'add a command', 'CLI design', 'agent-friendly output', or any task involving command-line tool creation.

Optimize blockchain gas costs by analyzing prices, patterns, and timing. Use when checking gas prices, estimating costs, or finding optimal windows. Trigger with phrases like "gas prices", "optimize gas", "transaction cost", "when to transact".

Turn a Kibana JSON log export into a runnable pytest suite using the secure-log2test CLI. Use when the user has a Kibana or Elasticsearch JSON export of API traffic and wants a regression suite from production logs, when extracting test cases from staging traffic, when scrubbing auth headers or secret-looking body fields before logs leave the laptop, when bridging Kibana-captured requests into a pytest-based suite for CI, when the user mentions Kibana logs, Elasticsearch JSON export, log-to-test conversion, log replay tests, auth header redaction, PII in logs, or regression tests from production traffic.

Implements real-time WebSocket communication with connection management, room-based messaging, and horizontal scaling. Use when building chat systems, live notifications, collaborative tools, or real-time dashboards.

Structured approach to workplace conflicts, performance discussions, and challenging feedback using preparation-delivery-followup framework. Use when preparing for tough conversations, addressing conflicts, giving critical feedback, or navigating sensitive workplace discussions.

Create and present web-based slidedecks for developers using Slidev with Markdown, Vue components, code highlighting, animations, and interactive features. Use when building technical presentations, conference talks, code walkthroughs, teaching materials, or developer decks.

Uses Chrome DevTools via MCP for efficient debugging, troubleshooting and browser automation. Use when debugging web pages, automating browser interactions, analyzing performance, or inspecting network requests. This skill does not apply to `--slim` mode (MCP configuration).

Move issues and external PRs through a state machine of triage roles — categorise, verify, grill if needed, and write agent-ready briefs.

Extract abstract mathematical models from functional code (Haskell, OCaml, F#) for formal reasoning in Isabelle/HOL. Use when users need to: (1) Convert functional programs to Isabelle definitions, (2) Extract high-level algorithm essence from implementation code, (3) Generate formal specifications and properties from code, (4) Create verification-ready models that capture mathematical properties while abstracting away implementation details. Focuses on structural recursion, algebraic data types, higher-order functions, and invariant extraction.

Guide for using Netlify Database — the GA managed Postgres product built into Netlify. Use when a project needs any kind of dynamic, structured, or relational data. Covers provisioning via @netlify/database, Drizzle ORM (@beta) setup, migrations, preview branching, and safe production data handling. Blobs is only for file/asset storage — any dynamic data belongs in the database.

Configure CI/CD pipelines for Fireflies.ai integrations with GraphQL testing. Use when setting up automated testing, configuring GitHub Actions, or validating Fireflies.ai queries in your build process. Trigger with phrases like "fireflies CI", "fireflies GitHub Actions", "fireflies automated tests", "CI fireflies", "test fireflies pipeline".

Implement real-time streaming transcription with Deepgram WebSocket. Use when building live transcription, voice interfaces, real-time captioning, or voice AI applications. Trigger: "deepgram streaming", "real-time transcription", "live transcription", "websocket transcription", "voice streaming", "deepgram live".

Use this skill any time a spreadsheet file is the primary input or output. This means any task where the user wants to: open, read, edit, or fix an existing .xlsx, .xlsm, .csv, or .tsv file (e.g., adding columns, computing formulas, formatting, charting, cleaning messy data); create a new spreadsheet from scratch or from other data sources; or convert between tabular file formats. Trigger especially when the user references a spreadsheet file by name or path — even casually (like "the xlsx in my downloads") — and wants something done to it or produced from it. Also trigger for cleaning or restructuring messy tabular data files (malformed rows, misplaced headers, junk data) into proper spreadsheets. The deliverable must be a spreadsheet file. Do NOT trigger when the primary deliverable is a Word document, HTML report, standalone Python script, database pipeline, or Google Sheets API integration, even if tabular data is involved.

Interface for MCP (Model Context Protocol) servers via CLI. Use when you need to interact with external tools, APIs, or data sources through MCP servers, list available MCP servers/tools, or call MCP tools from command line.
