mobile-debugging
Use for React Native / Expo troubleshooting (Metro bundler, native modules, simulator/emulator issues).
taskflow-integration
Optional TaskFlow integration for AppGen projects
lisp-validator
Validate Lisp code (Clojure, Racket, Scheme, Common Lisp) for syntax errors, parenthesis balance, and semantic issues. This skill should be used when validating Lisp code files, checking for syntax errors before execution, or validating LLM-generated Lisp code including incomplete or partial expressions. Provides structured JSON output optimized for automated workflows.
infrastructure-as-code
Infrastructure as Code using Terraform, Ansible, and CloudFormation. Master declarative infrastructure management.
debug
Debug your application to find and fix a bug or errors
automatic-stateful-prompt-improver
Automatically intercepts and optimizes prompts using the prompt-learning MCP server. Learns from performance over time via embedding-indexed history. Uses APE, OPRO, DSPy patterns. Activate on "optimize prompt", "improve this prompt", "prompt engineering", or ANY complex task request. Requires prompt-learning MCP server. NOT for simple questions (just answer them), NOT for direct commands (just execute them), NOT for conversational responses (no optimization needed).
global-conventions
Follow project-wide development conventions for file structure, documentation, version control, environment configuration, and code review processes. Use this skill when organizing project files and directories. When working with Git commits, branches, or pull requests. When managing environment variables or configuration files. When updating README or documentation files. When working with dependencies or package management. When considering feature flags or changelog entries.
atlassianapi
Atlassian API integration for Jira and Confluence automation. Activate for Atlassian REST APIs, webhooks, and platform integration.
async-python-patterns
Implement AsyncIO patterns for I/O-bound tasks with asyncio.gather, semaphores, and FastAPI async endpoints. Use for concurrent operations, parallel HTTP fetches, rate-limited operations, or async API development. Achieves near-linear scaling with concurrent tasks and minimal overhead. Triggers on "async", "asyncio", "concurrent", "parallel requests", "FastAPI async", "aiohttp", "async Python".
adaptivex-brand-guidelines
Applies AdaptiveX's official brand colors and typography to any sort of artifact that may benefit from having AdaptiveX's look-and-feel. Use it when brand colors or style guidelines, visual formatting, or company design standards apply for AdaptiveX training and consulting materials.
jelly-mixpanel-schema-skill
Create and validate Mixpanel event schemas in YAML format. Generate type-safe event definitions for multiple platforms (TypeScript, Kotlin, Swift). Activated when defining Mixpanel events, creating event schemas, or generating tracking code.
frontend-design
Create distinctive, production-grade frontend interfaces that avoid generic AI slop aesthetics
smalltalk-developer
This skill should be used for Pharo Smalltalk development tasks including:
anti-fabrication
Ensure factual accuracy by validating claims through tool execution, avoiding superlatives and unsubstantiated metrics, and marking uncertain information appropriately
ai-slop-detector
Use when reviewing code for AI-generated quality issues, detecting patterns of low-quality AI output, or auditing codebases with significant AI-assisted development. Provides systematic detection, prevention, and remediation strategies with human oversight and CI/CD integration. Triggers on "AI-generated code", "code quality", "AI slop", "review code", "detect AI patterns", "audit codebase", "quality issues", "slopsquatting", "hallucinated packages".
prototype
Create quick React prototypes that bundle to a single HTML file. Use for demos, interactive experiments, or shareable artifacts - NOT for full apps (use audreygen/Next.js for those).
chapter-content-generator
This skill generates comprehensive chapter content for intelligent textbooks after the book-chapter-generator skill has created the chapter structure. Use this skill when a chapter index.md file exists with title, summary, and concept list, and detailed educational content needs to be generated at the appropriate reading level with rich non-text elements including diagrams, infographics, and MicroSims. (project, gitignored)
codebase-audit
Audit and map a codebase to understand structure, dependencies, and risks. Use when the user asks to audit a repo, understand architecture, or assess codebase quality or health.
jelly-codex-skill
Invoke Codex CLI for complex coding tasks requiring high reasoning capabilities. Activated when users explicitly mention "Codex", request complex implementation challenges, advanced reasoning, GPT-5.1 capabilities, or need high-reasoning model assistance.
plan-and-design-page
Plan to implement a page in sveltekit by listing out the components need to create or to use
