Service layer patterns with createTaggedError, namespace exports, and Result types. Use when creating new services, defining domain-specific errors, or understanding the service architecture.
Expert GDScript best practices including static typing (var x: int, func returns void), signal architecture (signal up call down), unique node access (%NodeName, @onready), script structure (extends, class_name, signals, exports, methods), and performance patterns (dict.get with defaults, avoid get_node in loops). Use for code review, refactoring, or establishing project standards. Trigger keywords: static_typing, signal_architecture, unique_nodes, @onready, class_name, signal_up_call_down, gdscript_style_guide.
Automates the process of exporting data from Letterly and saving it to your Obsidian vault.
Turn any concept, idea, or description into a polished static HTML visual, then export it as a PNG or SVG image. Use this skill whenever the user wants to create a visual representation of an idea and needs an image file output (PNG or SVG). This includes: infographics, concept diagrams, flowcharts, comparison charts, process visuals, educational diagrams, social media graphics, data visualizations, posters, cards, badges, icons, logos sketches, or any "make me an image of X" request that can be achieved with HTML/CSS/SVG rather than photographic AI generation. Also trigger when the user has an existing HTML visual and wants to export/convert it to PNG or SVG. Trigger phrases include: "create an image of", "make a visual", "design a graphic", "export as PNG", "save as SVG", "concept to image", "turn this into an image", "screenshot this HTML", "generate an infographic", or any request combining a concept description with image output.
Creates animated GIFs optimized for Slack with proper dimensions (128x128 emoji, 480x480 message), FPS control, color optimization, and file size constraints. Use when asked to "make a GIF for Slack", "create an animated emoji", "design a Slack GIF", or "animate this for Slack". Provides GIFBuilder utilities, frame management, color palette reduction, and validation tools ensuring GIFs meet Slack requirements. Works with Python Pillow (PIL) for frame generation, color quantization, and GIF export with FPS 10-30 and duration under 3 seconds for emoji.
Generates or updates a README.md for a domain library. Analyzes the library's source code, exports, NgRx stores, services, and components to produce accurate architecture documentation. Use when a library is missing a README or when it needs updating.
Guide for exposing PostHog product endpoints as MCP tools. Use when creating new or updating API endpoints, adding MCP tool definitions, scaffolding YAML configs, or writing serializers with good descriptions. Covers the full pipeline from Django serializer to generated TypeScript tool handler.
Run an offline ASO audit on pulled App Store metadata and surface keyword gaps using Astro MCP. Use after pulling metadata with asc migrate export or asc localizations download.
Review code after implementation work to identify design flaws, abstraction issues, or maintenance risks that only became clear once real code was written. Use whenever the user asks whether a recent change exposed architectural problems, whether an abstraction is fighting the implementation, or whether a refactor is justified. Be conservative and avoid suggesting refactors without concrete evidence of recurring cost or complexity.
Apply when working with GraphQL schema files in graphql/ or implementing resolvers in node/resolvers/ for VTEX IO apps. Covers schema.graphql definitions, @cacheControl and @auth directives, custom type definitions, and resolver registration in the Service class. Use for exposing data through GraphQL queries and mutations with proper cache control and authentication enforcement.
Generate falsifiable trade strategy hypotheses from market data, trade logs, and journal snippets. Use when you have a structured input bundle and want ranked hypothesis cards with experiment designs, kill criteria, and optional strategy.yaml export compatible with edge-finder-candidate/v1.
Create part assembly animations for SVG vector graphics with a strong sense of power and speed, and support one-click export of 30fps sequence frames with transparent background. It is suitable for scenarios where static SVG needs to be converted into transparent assets for video editing (such as AE/PR).
