This skill is the PREREQUISITE for base44-sdk - always use this first for new projects befo...

Use for writing JavaScript/TypeScript code with the Base44 SDK in EXISTING projects. Triggers: user wants to implement features, build functionality, or write code using Base44; code uses '@base44/sdk' imports; user mentions SDK methods like base44.entities, base44.auth, base44.agents, base44.functions, base44.integrations; user says 'add a feature', 'implement', 'build component', 'write code for'. NOT for: creating new projects, CLI commands (npx base44 create/deploy/login), or directories ...

Get a second opinion via Codex MCP. Use for stress-testing ideas, getting fresh perspective, steelmanning arguments, or iteratively refining work through expert back-and-forth. Invoke for ANY request involving external review, feedback, or consultation.

Create, edit, and refine agent skills through co-development and eval loops. Use for ANY question about skills or request to create/modify them.

Guidance on choosing and using Cursor agent modes: Agent, Ask, Plan, and Debug. Use when selecting the right mode for a task or when explaining mode capabilities.

Agent Review workflows and best practices for catching bugs before merging. Use for reviewing agent-generated code and local changes.

Browser testing, design-to-code conversion, accessibility auditing, and visual debugging. Use for web development, testing, and design implementation.

Generate changelog entries. Use on releases or PR merges. Parses git commits, categorizes changes, formats changelog entries, and updates CHANGELOG.md.

Effective use of @ mentions, context window optimization, and semantic search strategies. Use for managing context efficiently and providing targeted references.

Debug mode workflows and best practices for troubleshooting bugs, regressions, and performance issues. Use when debugging tricky issues that standard agent interactions struggle with.

Mermaid diagram generation for architecture visualization, data flow diagrams, and component relationships. Use for documentation, PR descriptions, and architectural analysis.

Automate documentation updates when API endpoints, functions, or architecture change. Detects code changes that require doc updates, generates API reference from FastAPI routers, updates architecture diagrams, and syncs between internal and external docs.

Automate issue triage using ISSUE_TRIAGE_GUIDE.MD. Use when analyzing GitHub issues. Scores issues using triage formula, assigns priority levels, suggests lane assignment, and maps to Omi layers.

Automate PR workflows. Use before creating PRs. Generates PR descriptions, validates PR requirements, checks for missing tests/docs, and links issues automatically.

Skill for programmatically reading, updating, and creating Cursor rules based on patterns and lessons learned

Meta-skill for analyzing PRs, issues, and user interactions to improve Cursor rules and skills automatically

Execute bash commands against any public GitHub repository without cloning it locally. Use when the user needs to explore, search, or analyze external repos, check dependency source code, or investigate implementation details in third-party code.

This skill should be used when the user asks to "create a slash command", "write a command file", "add command to plugin", "create /command", "write command frontmatter", "add command arguments", "configure command tools", needs guidance on command structure, YAML frontmatter fields (description, argument-hint, allowed-tools), markdown command body, or wants to add custom slash commands to Claude Code plugins with proper argument handling and tool restrictions.

This skill should be used when users need to scrape websites, extract structured data, handle JavaScript-heavy pages, crawl multiple URLs, or build automated web data pipelines. Includes optimized extraction patterns with schema generation for efficient, LLM-free extraction.

Generate markdown documentation from Python codebases by analyzing source files, extracting docstrings, type hints, and code structure. Use when the user asks to document Python code, create API docs, or generate README files from source code.
