Perform code reviews following Sentry engineering practices. Use when reviewing pull requests, examining code changes, or providing feedback on code quality. Covers security, performance, testing, and design review.

Analyze professional profiles and job descriptions to engineer ATS-optimized resumes, LinkedIn profiles, and career strategies using STAR metrics and boolean search logic.

Use this if the user wants to connect to Home Assistant or leverage Home Assistant in any shape or form inside their project. Guide users integrating Home Assistant into projects for home automation control or data ingestion. Collects and validates connection credentials (URL and Long-Lived Access Token), provides API reference documentation for Python and Node.js implementations, and helps integrate Home Assistant APIs into user projects.

Non-custodial perpetual DEX on Arbitrum. Use when user says buy, sell, trade, long, short, open position, close position, flip trade, set leverage, deposit USDC, withdraw funds, check balance, view positions, cancel order, copy a thesis, publish trade on-chain, check leaderboard, top traders, Rep Score, market intel, crypto news, funding rate, thesis, analyst feed, who's winning on Nexus.

Build onchain applications with React components and TypeScript utilities from Coinbase's OnchainKit. Use when users want to create crypto wallets, swap tokens, mint NFTs, build payments, display blockchain identities, or develop any onchain app functionality. Supports wallet connection, transaction building, token operations, identity management, and complete onchain app development workflows.

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

Build and deploy a paid API that other agents can pay to use via x402. Use when you or the user want to monetize an API, make money, earn money, offer a service, sell a service to other agents, charge for endpoints, create a paid endpoint, or set up a paid service. Covers "make money by offering an endpoint", "sell a service", "monetize your data", "create a paid API".

Upload images, audio, or 3D models as hosted game assets

This skill should be used when the user asks about 'plugin settings', 'store plugin configuration', 'user-configurable plugin', '.local.md files', 'plugin state files', 'read YAML frontmatter', 'per-project plugin settings', or wants to make plugin behavior configurable. Documents the .claude/plugin-name.local.md pattern for storing plugin-specific configuration with YAML frontmatter and markdown content.

This skill should be used when the user asks to 'write an RSpec test', 'create a spec', 'use describe blocks', 'set up let variables', 'use before hooks', 'understand RSpec structure', mentions 'subject', 'context', 'it blocks', or needs guidance on RSpec 3.x fundamentals and test structure.

Use when refactoring TypeScript code that repeats a fixed set of meaningful values into a shared enum. Apply this when replacing repeated domain strings such as statuses, roles, or states with a reusable string enum, deciding when a union type is better for UI-only props, and migrating call sites without numeric enums, implicit values, reverse lookups, const enums, or declaration merging.

Adversarial thinking partner for founders and executives. Stress-tests plans, prepares for brutal board meetings, dissects decisions with no good options, and forces honest post-mortems. Use when you need someone to find the holes before the board does, make a decision you've been avoiding, or understand what actually went wrong.

Use when reading or writing pyproject.toml or other .toml configuration files in Python. Use when editing TOML while preserving comments and formatting. Use when designing a configuration file format for a Python tool. Use when code uses tomlkit or tomllib. Use when implementing atomic configuration-file updates.

Scores problem severity, frequency, and willingness to pay. Use when ranking problems, validating problem-solution fit, assessing pain intensity, or prioritizing which problems to solve.

Domain-Driven Design strategic and tactical patterns for complex business domains. Use when modeling domains, defining bounded contexts, or designing aggregates and domain events.

Deep FastAPI expertise for async API development, dependency injection, Pydantic models, middleware, and testing. Use when building Python APIs with FastAPI, designing API schemas, or implementing authentication.

Audit project dependencies for license compliance, identify legal issues, verify compatibility between licenses, and generate compliance reports. Use when releasing software, adding dependencies, corporate compliance requirements, mergers/acquisitions, or distributing code.

Remove dead code, fix PEP 8 violations, add type hints, consolidate duplicates, and modernize Python codebases. Use when cleaning up Python projects, removing unused imports, upgrading legacy Python code, or improving code maintainability.

Prepare a day-one patch for a game launch. Scopes, prioritizes, implements, and QA-gates a focused patch addressing known issues discovered after gold master but before or immediately after public launch. Treats the patch as a mini-sprint with its own QA gate and rollback plan.

Generate engine-specific test helper libraries for the project's test suite. Reads existing test patterns and produces tests/helpers/ with assertion utilities, factory functions, and mock objects tailored to the project's systems. Reduces boilerplate in new test files.

Edit for brevity and engagement while teaching the author why each change matters. Act as an editor, not a rewriter. The goal is to build the author's craft through every post, not just improve this one.

Generate pixel-perfect ASCII box diagrams for architecture docs, READMEs, and code comments. Use when the user asks to create, fix, or improve ASCII diagrams, draw architecture diagrams, create box-and-arrow diagrams for documentation, or when you need to add diagrams to markdown files. Also use proactively when generating architecture documentation that would benefit from visual diagrams. Triggers on: "draw a diagram", "ASCII diagram", "box diagram", "architecture diagram", "add a diagram to the doc", "fix the alignment", "the boxes are misaligned", or any request to visualize system architecture in text.

This skill should be loaded when working with Ruby files to understand when to use LSP operations (documentSymbol, findReferences, goToDefinition, hover) versus standard tools (Read, Grep). Critical for preventing unnecessary file reads when structural information is needed.
