Idiomatic Go patterns, best practices, and conventions for building robust, efficient, and maintainable Go applications.

Walks through ORM patterns, REST API structure, caching layers, and middleware setup so your Django codebase doesn't become a mess at scale.

Takes a Python file or snippet and flags deviations from PEP 8, missing type hints, and suggests idiomatic rewrites that make the code harder to break.

Guides you through test-driven development: writes unit, integration, and E2E tests first, then implements the feature to pass them, ensuring 80%+ coverage.

Checks your C++ against the Core Guidelines—catches unsafe patterns, outdated idioms, and missed opportunities for clarity. Returns specific line-by-line fixes.

Pulls public data on market size, competitor positioning, funding rounds, and tech stacks, then organizes it into a decision-ready one-pager with sources and gaps flagged.

Tracks conversation length and suggests when to compress history—between phases, after decisions, or before a new topic—so Claude stays sharp without losing the thread.

Walks through the migration strategy for your specific database and ORM — PostgreSQL, MySQL, Prisma, Drizzle, etc. — with rollback steps and zero-downtime sequencing.

Sets up a test harness that runs assertions against Claude's code outputs, gives you pass/fail, and surfaces failure cases so you can iterate toward a working solution.

Proposes the right architecture layer for your next feature—routing, service, queue, event, or cache—and shows code patterns that match production Laravel conventions.

Reads a failing or intermittent test, the code under test, and your GoogleTest/CTest setup, then pinpoints the root cause and suggests a fix with minimal changes.

Verifies migrations, linting, test coverage, security, and deployment readiness in one pass. Surfaces blockers before a release or PR lands.

Routes simple tasks to cheaper models, caches repeated prompts, batches requests, and tracks spend per feature. Includes pre-built retry logic and budget guards.

Scaffolds an agent with built-in eval gates, task decomposition, and smart model routing so each step uses the right tool for the job—not the biggest one.

Generates unit, integration, and async tests for Rust code with proper mocks and fixtures. Follows TDD patterns so tests clarify the contract before implementation.

Implements a content-hash-based cache layer that auto-invalidates when file content changes, avoiding redundant processing without manual cache busting.

Takes a single insight, research finding, or product update and generates platform-native content for X, LinkedIn, TikTok, YouTube, and newsletters—each formatted and toned for its audience.

Engineering operating model for teams where AI agents generate a large share of implementation output.

Scaffolds an in-memory cache backed by files using Swift actors, eliminating data races. Handles concurrent reads and writes without locks or semaphores.

Generates PHPUnit and Pest tests for your Laravel models, routes, and jobs. Includes factory setup, database isolation, and coverage targets so you know what's still exposed.

Reviews your Kotlin code and suggests null-safe patterns, coroutine idioms, and DSL builders that align with language conventions. Spots common anti-patterns.

Uses Apple's FoundationModels framework to run text generation, guided generation, and tool calling on-device in iOS 18+, with no server round-trips or API keys.

Writes idiomatic Jetpack Compose and Multiplatform Compose code for state management, navigation, theming, and platform-specific UI — ready to paste into a KMP project.

Explains incremental bundling and filesystem caching in Turbopack, diagnoses whether your project will benefit, and walks through the migration from webpack step-by-step.

Runs formatting, linting, and Claude-powered fixes on files as they're edited, catching style drift and common mistakes before code review.

Generates idiomatic Kotlin tests using Kotest and MockK, with property-based testing and coroutine patterns. Includes coverage reporting to flag untested paths.

Maps your product category, destination, and HS code against tariff schedules and trade agreements to flag compliance risks before you ship.

Explains Nuxt 4 hydration pitfalls, SSR-safe fetching patterns, and route-rule setup. Catches the common async-data mistakes that tank performance or break on deploy.

Runs automated clicks and assertions across key user flows after each deploy, comparing screenshots and form submissions against a baseline to flag visual regressions.

Syncs with your Jira board to fetch tickets, extract requirements, and log updates or comments without switching tabs. Works via API or MCP.

Best practices for Remotion - Video creation in React. 29 domain-specific rules covering 3D, animations, audio, captions, charts, transitions, and more.

Use this skill to measure performance baselines, detect regressions before/after PRs, and compare stack alternatives.

Scans your entire repo across all languages, catalogs every dependency and embedded library, and flags security, license, and technical-debt risks with a browsable report.

Takes a customer complaint, feature request, or market observation and breaks it down by jobs-to-be-done, user segment, competitive pressure, and moat opportunity.

Assembles four distinct voices (pragmatist, optimist, skeptic, devil's advocate) to debate a decision, surface real tradeoffs, and help you choose without regret.

Hits your live URL after a deploy and checks HTTP status, streaming endpoints, asset loads, browser console, and performance metrics. Reports any regression in one view.

Production-ready Dart and Flutter patterns covering null safety, immutable state, async composition, widget architecture, popular state management frameworks (BLoC, Riverpod, Provider), GoRouter navigation, Dio networking, Freezed code generation, and clean architecture.

Builds a Manim script that animates graphs, system diagrams, or product flows step-by-step. Output is ready to render or hand to a video team.

Scripts and records an automated walkthrough of your web app with a visible cursor, natural pauses, and a professional feel—no manual screen recording needed.

Scores leads on buying signals and mutual connections, models their communication style from past posts, then drafts personalized outreach across email, LinkedIn, and X—ready to send.

Finds, summarizes, edits, and migrates Google Docs, Sheets, and Slides across your workspace without context-switching. Handles bulk cleanup, version tracking, and shared-doc conflicts.

Forks your private codebase, removes credentials and internal references, and packages it as a public repo with a README and license — all in one run.

Reorganize the user's X and LinkedIn network with review-first pruning, add/follow recommendations, and channel-specific warm outreach drafted in the user's real voice. Use when the user wants to clean up following lists, grow toward current priorities, or rebalance a social graph around higher-signal relationships.

Knowledge base management, ingestion, sync, and retrieval across multiple storage layers (local files, MCP memory, vector stores, Git repos). Use when the user wants to save, organize, sync, deduplicate, or search across their knowledge systems.

Reviews your current setup—data handling, vendor agreements, access logs, breach protocols—against HIPAA requirements and flags specific compliance risks with remediation steps.

Maps the repo structure, identifies entry points and key modules, then generates a guided tour that explains what each part does and how they connect.

Reads the live ECC repository and answers questions about agents, skills, commands, hooks, and onboarding — always pointing to the current docs so you don't follow stale links.

Sketches out a multi-step agent that ingests market data, runs basket simulations, and flags opportunities for human review — without touching live orders.

Measures structural health (complexity, duplication, hotspots) on each file, shows the delta after your edits, and warns if a refactor actually made things worse.
