Flutter Test Runner
This skill provides a structured approach to running Flutter tests for the Sanmill project, covering unit, widget, and integration tests. It includes specific commands for different test types, coverage reporting, and troubleshooting common issues like MissingPluginException. The documentation clearly explains the difference between Dart VM tests and platform-specific integration tests that require the C++ AI engine.
pre-dev-feature-map
A highly structured and disciplined process for mapping feature relationships before technical design, preventing architectural mismatches and ensuring business-aligned development.
metabolomics-workbench-database
Provides direct REST API access to the NIH Metabolomics Workbench database with 4,200+ studies. Enables querying metabolites, RefMet nomenclature standardization, MS/NMR data searches, study metadata retrieval, and m/z-based compound identification for metabolomics research workflows.
codex-skill
Use when user asks to leverage codex, gpt-5, or gpt-5.1 to implement something (usually implement a plan or feature designed by Claude). Provides non-interactive automation mode for hands-off task execution without approval prompts.
payload
Use when working with Payload CMS projects (payload.config.ts, collections, fields, hooks, access control, Payload API). Use when debugging validation errors, security issues, relationship queries, transactions, or hook behavior.
conference-talk-builder
Create conference talk outlines and iA Presenter markdown slides using the Story Circle narrative framework. Use when the user wants to structure a tech talk, create presentation slides, or needs help organizing talk ideas into a story-driven format.
datacommons-client
Provides Python client access to Data Commons API for querying public statistical data like population, economic indicators, and health statistics. Includes entity resolution, time-series queries, and knowledge graph exploration with clear examples for common workflows.
nextjs-stripe-integration
Add Stripe payment processing to Next.js projects. Implement checkout sessions, payment handling, subscriptions, webhooks, and customer management. Use when adding Stripe to a Next.js project, building payment flows, implementing subscriptions, or integrating payment processing.
diffdock
Diffusion-based molecular docking. Predict protein-ligand binding poses from PDB/SMILES, confidence scores, virtual screening, for structure-based drug design. Not for affinity prediction.
backend-dev-guidelines
Provides detailed implementation guidelines for a specific Langfuse monorepo using Next.js 14, tRPC, BullMQ, and TypeScript. Includes checklists for tRPC features, public API endpoints, and queue processors. Covers layered architecture, dual databases (PostgreSQL + ClickHouse), tenant isolation, and testing strategies.
writing-skills
Create and manage Claude Code skills in HASH repository following Anthropic best practices. Use when creating new skills, modifying skill-rules.json, understanding trigger patterns, working with hooks, debugging skill activation, or implementing progressive disclosure. Covers skill structure, YAML frontmatter, trigger types (keywords, intent patterns), UserPromptSubmit hook, and the 500-line rule. Includes validation and debugging with SKILL_DEBUG. Examples include rust-error-stack, cargo-dependencies, and rust-documentation skills.
typescript-type-safety
Use when encountering TypeScript any types, type errors, or lax type checking - eliminates type holes and enforces strict type safety through proper interfaces, type guards, and module augmentation
skill-packager
A well-structured skill packaging tool with excellent security checks and clear workflows for preparing Claude skills for deployment.
aesthetic
This skill provides a structured four-stage framework for creating and evaluating UI designs. It guides users from aesthetic analysis to functional implementation, micro-interactions, and storytelling. It integrates with other MCP tools for screenshot capture and AI image generation/analysis, offering concrete workflows for design iteration.
Fixing Bugs Systematically
Provides a structured protocol for diagnosing software bugs with clear investigation paths. Differentiates between simple and complex bugs, uses parallel agent investigation for multi-system issues, and includes validation steps before implementation. Ties fixes back to existing documentation like feature specs and user stories.
