Coding standards, frameworks, refactoring, and code review (16.9K skills)
Build and maintain interfaces with shadcn/ui by finding, adding, and combining components. The skill uses project settings, component documentation, and change previews to guide styling, debugging, preset changes, and updates that preserve local edits.
Review code changes for compatibility between a desktop app and den, its cloud API. It flags changes that could break published apps, identifies desktop features depending on unavailable APIs, and explains the required rollout order.
Manage OpenWork feature releases with feature flags, switches that control access to new behavior. Register features before coding, release them by organization and deployment, prepare a global shutdown option, and remove temporary flags after rollout.
Review changed UI code against numbered rules in DESIGN.md. Findings identify the relevant rule, affected lines, and a small fix for issues such as wording, component reuse, visual styling, accessibility, or missing screenshot evidence.
Attach screenshots, images, or videos to GitHub pull requests and issues using GitHub CLI. It also covers embedding images within comment text, adding alternative text, and retrieving an uploaded asset’s URL from the posted comment.
Use the Archon CLI to launch AI workflows on projects, inspect their results, and approve, reject, cancel, or resume runs. The skill also guides setup, configuration changes, workflow creation, and improvements to workflow prompts.
Delegate checks for AGENTS.md rule violations to a dedicated agent. It scans the codebase, fixes high-impact issues in a separate working copy, runs full validation, and creates a pull request, tracking progress across runs through memory.
Organize GitHub issues by reading their full descriptions and adding labels for type, effort, priority, and affected area. Preserve existing labels, fill missing categories, and summarize the reasoning alongside duplicate, related, or blocking issue relationships.
Create, edit, and validate URDF files describing robot structure. Check links, joints, coordinate frames, units, mesh placement, and mass properties, then use CAD Viewer to inspect the model and review each movable joint.
Create, edit, and validate SDFormat files that describe robots and simulation worlds. Check coordinate frames, joints, geometry, and physical properties, review models in CAD Viewer, and report assumptions and compatibility risks before simulator handoff.
Create and validate SRDF files that define how MoveIt2 plans robot motion. Check planning groups, named poses, end effectors, and collision exclusions against an existing URDF robot model, then review the model visually.
Build n8n workflows that download, transform, and send files without losing their contents. Learn how file data differs from JSON, how to preserve attachments, and how to use storage keys or URLs with AI tools and chat messages.
Build custom calculation and parsing tools that an n8n AI Agent can call. This skill covers JavaScript or Python inputs, structured arguments, string results, tool descriptions, and fixes for invocation and output errors.
Write JavaScript for n8n Code nodes to aggregate, filter, and transform workflow data. Guidance covers data access, output formats, execution modes, common errors, and performance choices when processing large numbers of records.
Add error handling to n8n workflows with connected error outputs, retries, and failure notifications. Return HTTP status codes that explain what went wrong, distinguish invalid requests from service failures, and keep internal error details out of public responses.
Configure n8n nodes by checking which fields each operation needs and which settings reveal additional options. Start with a minimal configuration, validate it, look up unclear properties, and make targeted edits to existing code or text fields.
Write and troubleshoot n8n expressions, the formulas that pass and transform data between workflow steps. Covers field references, webhook inputs, dates, strings, and choosing between expressions and Code nodes for data transformations.
Write Python for n8n Code nodes to transform, filter, aggregate, and validate workflow data. Get guidance on reading input items, returning the required JSON structure, using standard library modules, and avoiding common errors within n8n's Python execution modes.
Build Telegram bots, Mini Apps that run inside Telegram, and custom clients using implementation examples. The guide covers message handling, interactive buttons, payments, authentication, storage, and receiving updates through webhooks or long polling.
Learn Claude Code workflows through a Chinese-language guide covering tool use, large-file analysis, task tracking, and troubleshooting. It also explains MCP, a protocol for connecting external systems, alongside development and review patterns.
Build applications that use Polymarket market data and trading APIs. The skill guides live monitoring through WebSocket connections, which receive ongoing updates, including trades, orders, market comments, and cryptocurrency prices.
Develop cryptocurrency trading bots with Hummingbot documentation and code examples. Explore exchange connections, price and order book data, and strategies such as market making, which places buy and sell orders, or arbitrage across markets.
Get documentation-based help with PostgreSQL queries, database design, administration, and performance tuning. The supplied reference also explains connection settings and libpq, PostgreSQL’s C client library, for investigating connection failures and implementing connection handling.
Build cryptocurrency exchange integrations with CCXT in JavaScript, Python, or PHP. The skill helps retrieve market data, manage orders, automate trading workflows, check exchange-specific capabilities, and investigate API errors using reproducible examples and logs.
