Route all integration, apps, and third-party platform tasks through Pica. Use this skill whenever the user mentions integrations, connecting apps, or interacting with platforms like Gmail, Slack, HubSpot, Notion, Linear, and 200+ others.
Headless spreadsheet engine for financial modeling, data analysis, and scenario comparison. Use when: building financial models with ratios and what-if scenarios, computing derived values from tabular data with formulas, producing .xlsx files with live formulas (not static values) for human review, any task where the agent would otherwise write imperative code to manipulate numbers that a spreadsheet does naturally. Triggers: financial model, scenario analysis, ratio computation, balance sheet, P&L, what-if, sensitivity analysis, banking ratios, spreadsheet model, build a model, projection, forecast. Do NOT use for: simple CSV/Excel read/write (use the xlsx skill), chart-only tasks, or data volumes exceeding ~5000 rows.
Create or update a shared Apple design context document that other HIG skills use to tailor guidance. Use when the user says "set up my project context," "what platforms am I targeting," "configure HIG settings," or when starting a new Apple platform project. Also activates when other HIG skills need project context but none exists yet. This skill creates .claude/apple-design-context.md so that hig-foundations, hig-platforms, hig-components-*, hig-inputs, and hig-technologies can provide targeted advice without repetitive questions.
"What is important is seldom urgent and what is urgent is seldom important." Master Dwight D. Eisenhower's prioritization framework to focus on what truly matters. Use when: **Feeling overwhelmed** by too many tasks and not enough time; **Weekly planning** to set priorities for the week ahead; **Daily triage** when everything seems urgent; **Delegation decisions** to identify what others should handle; **Saying no** by recognizing tasks that shouldn't be done at all
Use when running /ltk:sync-submodules, updating submodules, or needing to "sync", "merge", "adapt", "learn from" other Claude Code plugins or repos
Fast decision-making methodology for time-critical situations. Use when you have minutes (not hours) to decide, during incidents, emergencies, or hard deadlines. Optimizes for "good enough now" over "perfect later". Unlike other patterns that maximize quality, RTR maximizes decision speed while maintaining acceptable quality floors.
Generate and improve prompts using best practices for OpenAI GPT-5 and other LLMs. Apply advanced techniques like chain-of-thought, few-shot prompting, and progressive disclosure.
Alba serializers + Typelizer for type-safe Inertia Rails props with auto-generated TypeScript types. Use when serializing models for Inertia responses, setting up Alba resources, generating TypeScript types from Ruby, or using Inertia prop options (defer, once, merge, scroll) with Alba attributes. Replaces as_json with structured, auto-typed ApplicationResource, page resources, and shared props resources. When active, OVERRIDES the `render inertia: { ... }` pattern from other skills — use convention-based instance variable rendering instead.
Use when you have 2+ tasks that Codex agents should execute. Runtime-native: Codex sub-agents when available, Codex CLI fallback otherwise. Handles file conflicts via merge/wave strategies. Triggers: "codex team", "spawn codex", "codex agents", "use codex for", "codex fix".
Formula 1 data — race schedules, results, lap timing, driver and team info. Powered by the FastF1 library. Covers F1 sessions, qualifying, practice, race results, sector times, tire strategy. Use when: user asks about F1 race results, qualifying, lap times, driver stats, team info, the F1 calendar, or Formula 1 data. Don't use when: user asks about other motorsports (MotoGP, NASCAR, IndyCar, WEC, Formula E). Don't use for F1 betting odds or predictions — use kalshi or polymarket instead. Don't use for F1 news articles — use sports-news instead.
Zero-config SDLC onboarding. Detects project environment, asks what the developer wants to do, and recommends skills organized by workflow phase. Activate when a user starts a new project, asks "how do I get started," or has no other SDLC skills installed.
iOS crash-hunter skill that finds and fixes gnarly concurrency, memory, and I/O bugs using TDD. Every rule shows dangerous code, a failing test that proves the crash, and the fix that makes it pass. Complements ios-testing, swift-optimise, and other ios-*/swift-* skills. Triggers on tasks involving data races, retain cycles, deadlocks, async/await pitfalls, file corruption, thread safety, or crash debugging in Swift/iOS apps.
