Use when performing regression analysis with confidence intervals, solving ODEs, fitting models to experimental data, or caching expensive scientific computations - provides convenient wrappers around scipy that automatically calculate confidence intervals and prediction bounds for linear, nonlinear, and polynomial regression

This skill applies Edward Tufte's data visualization principles from "The Visual Display of Quantitative Information" to create high-impact slides. Use when designing presentations, creating charts/graphs, reviewing slides for clarity, or transforming data into visual displays. Triggers on phrases like "make a slide", "create presentation", "design chart", "visualize data", "review my slides", or "make this more impactful".

This skill should be used when the user wants to fill in TODO links, placeholder links, or missing links in markdown files. Invoke when the user mentions "fill links", "TODO links", "find links", or asks to add appropriate links to concepts in a document.

Expert in ODEs and PDEs covering solution methods, qualitative analysis, and applications to physics and engineering

Use when building iOS apps with xtool (Xcode-free iOS development), creating xtool projects, adding app extensions (widgets, share extensions), or configuring xtool.yml. Triggers on mentions of xtool, SwiftPM iOS apps, building iOS on Linux/Windows, or app extension setup.

Systematic approach to implementing new features in the Rust memory system following project conventions. Use when adding new functionality with proper testing and documentation.

Resolve merge conflicts intelligently using git history. Fetches PR context, identifies conflicted files, uses git blame and commit history to infer developer intent. Applies resolution strategies based on change type (bugfix, feature, refactor). Auto-resolves session artifacts and templates. Validates session protocol before push.

Expert in database schema design with focus on normalization, indexing strategies, FTS optimization, and performance-oriented architecture for desktop applications

Advises on choosing the right Claude Code extensibility approach (Skills, Commands, Subagents, Hooks, Plugins, MCP, Output Styles). Activates when user discusses extending Claude Code, creating automation, or is unsure which feature to use. Analyzes use cases and recommends appropriate solutions with trade-off explanations. Use when user mentions "should I use", "what's the best way", "skill or command", "which approach", or discusses extensibility options.

Observability patterns for Python applications. Triggers on: logging, metrics, tracing, opentelemetry, prometheus, observability, monitoring, structlog, correlation id.

Use when optimizing end-to-end latency, reducing response times, or improving performance for latency-sensitive applications. Covers latency budgets, geographic routing, protocol optimization, and latency measurement techniques.

Provides competitive visual audit frameworks and templates for brand identity work. Auto-activates during visual direction, color selection, typography selection, and positioning work. Use when discussing competitors, competitive audit, differentiation, white space, perceptual mapping, visual landscape, zig zag strategy, brand audit, color audit, typography audit, visual identity analysis, or positioning maps.

Interact with Safari browser tabs, reading list, bookmarks, and history via AppleScript. Use when the user asks to analyze, organize, summarize, deduplicate, close, export, or manage their Safari tabs. Also handles reading list, bookmarks, and history searches. Triggers include "my tabs", "open tabs", "Safari tabs", "clean up my browser", "what tabs do I have open", "organize my tabs", "too many tabs", "reading list", "bookmarks", "browser history", "export tabs". Requires macOS with Safari.

Apply R&D framework to optimize prompts and context. Use when optimizing context window usage, reducing prompt size, delegating to specialized agents, or applying systematic context management.
