Skills

Multi-agent harness inspired by Anthropic's March 2026 harness-design paper that separates Generator from Evaluator in an adversarial GAN-style loop to drive quality far beyond single-agent self-critique. Use for application builds, frontend design, or full-stack work where AI-slop aesthetics are unacceptable and you want to invest $50–200 on production-quality output.

Part of Google's official Agent Skills repository, providing skills for Google Cloud products and technologies including Gemini API, AlloyDB, BigQuery, Cloud Run, Cloud SQL, Firebase, GKE, along with recipes for onboarding, authentication, and Well-Architected Framework guidance.

AI product strategy skill using frameworks from 94 product leaders to guide architecture decisions, build-vs-buy evaluations, and AI roadmap planning

Domain-Driven Design skill for modeling software around business domains using bounded contexts, aggregates, ubiquitous language, domain events, and context mapping strategies.

Provides expert guidance for implementing secure, efficient, and compliant Stripe payment integration best practices

Generates business process and integration diagrams in PlantUML using three stencil families: `mxgraph.bpmn.*` (events, gateways, user/service/script/manual/business-rule tasks, data objects), `mxgraph.eip.*` (channels, routers, splitters, aggregators, translators, wire taps), and `mxgraph.lean_mapping.*` (supplier/customer, manufacturing process, supermarket, FIFO lane, kanban variants, kaizen burst). Supports BPMN pools/lanes via `rectangle "Pool" { ... }`, sequence flows (`-->`), and message flows (`..>`) for order processing, approval workflows, EIP messaging, ETL pipelines, value streams, and event-driven architectures.

Builds data-pipeline and analytics architecture diagrams in PlantUML using `mxgraph.aws4.*` stencils for query engines (Athena), ETL (Glue), streaming (Kinesis, MSK), MapReduce (EMR), data warehouse (Redshift), data lakes (Lake Formation, S3), BI (QuickSight), and database stencils (Aurora, RDS, DynamoDB, Neptune, ElastiCache, DocumentDB). Supports left-to-right pipeline layouts, batch (`-->`) vs streaming/CDC (`..>`) flows, and zone grouping for Data Lake, real-time, ETL, log analytics, ML feature store, and CDC architectures.

Operate across Google Drive, Docs, Sheets, and Slides as one workflow surface — finding, summarizing, editing, migrating, or cleaning up shared assets like plans, trackers, and decks. Uses Drive as the entry point, then switches to Docs/Sheets/Slides specialists with index-aware edits for Docs and explicit tab/range targeting for Sheets.

Tactical negotiation skill based on Chris Voss's 'Never Split the Difference' covering mirroring, labeling, calibrated questions, accusation audits, and the Ackerman bargaining method

from lijigang/ljg-skills

Production-ready Dart/Flutter patterns covering null safety with pattern matching, sealed `AsyncState` hierarchies, `freezed` immutability, structured concurrency via `Future.wait`, widget extraction with `const` propagation, BLoC/Riverpod/Provider state management, GoRouter with `refreshListenable` auth guards, and Dio interceptors with one-shot token refresh.

Wondel.ai agent skills for Claude Code and agentskills.io-compatible agents, installable via the plugin marketplace system.

Three-stage pipeline (Fork → Sanitize → Package) that turns any private project into a safely public release — stripping secrets, verifying the repo is clean, then generating CLAUDE.md, setup.sh, and README. Triggered by `/opensource fork|verify|package` or phrases like "open source this" and "make this public".

A collection of AI agent skills including GitHub Copilot SDK integration, covering building agentic applications with TypeScript, Python, Go, and .NET.

Guidance for creating, refactoring, and reviewing Microsoft Agent Framework applications (the unified successor to Semantic Kernel and AutoGen), with separate workflows for .NET and Python. Because the framework is still in public preview, the skill always grounds advice in the latest official documentation rather than stale knowledge.

Let-fate-decide skill from Trail of Bits for randomized decision-making in testing and fuzzing workflows.

A collection of Claude Code skills covering framework-specific development expertise including FastAPI, Python, and other technologies with best practices.

Curated collection of 50+ specialized AI agent personalities (engineering, design, marketing, sales, paid media) for Claude Code, Cursor, Aider, Windsurf, and Copilot, each with distinct expertise, workflows, and deliverables. Ships an interactive installer that auto-detects target tools and writes agent files to the right paths (`~/.claude/agents/`, `.cursor/rules/`, `.windsurf/rules/`, etc.).

Provides Redis performance optimization, data modeling, and operational best practices, from a collection of 240+ skills converted from Cursor rules.

AI-converted Get Shit Done productivity skills for Claude Code, providing task management and focus workflows originally from the GSD methodology.

Generates editorial-style HTML/CSS information cards embedded directly inside Markdown (no code fences, no empty lines in the HTML), with content analysed across density × structure × mood to choose layout and tone-sensed colour palettes (Philosophical, Technical, Literary, Scientific, Business, Creative). Enforces an anti-AI taste checklist — no centred hero, no equal-width tiles, no pure black, max 1 accent under 80% saturation, no purple-blue gradients, no AI phrasing — across 12 ready style templates and several layout skeletons.

Build durable background tasks with Trigger.dev that run reliably with automatic retries, queuing, and observability. Covers task creation, triggering from backend code, schema validation with Zod, scheduling cron jobs, and implementing concurrency control for AI agents and async workflows.

Deployment skill for the CreateOS cloud platform, enabling one-command shipping of AI agents, APIs, MCP servers, bots, frontends, webhooks, and workers with support for Node.js, Python, Go, Rust, Bun, and Docker via GitHub auto-deploy, Docker images, or file upload.

Operate real customer billing workflows via connected tools like Stripe — subscriptions, refunds, duplicate charges, failed renewals, churn triage, and billing-portal recovery. Enforces classifying the issue (accidental duplicate vs multi-seat vs broken product vs cancellation) before acting, and never refunds blindly or exposes secret keys or PII.

Professional document creation, editing, and analysis skill for Office formats (docx, pdf, pptx, xlsx), covering Word document creation with tracked changes, PDF extraction, PowerPoint presentations, and Excel spreadsheet manipulation.
