# Skills Repository Overview

This repository from Anthropic demonstrates implementations of skills for Claude, which are folders containing instructions, scripts, and resources that enhance Claude's performance on specialized tasks.

## Key Components

**What Skills Do:**
"Skills are folders of instructions, scripts, and resources that Claude loads dynamically to improve performance on specialized tasks." They enable Claude to handle company-specific workflows, data analysis procedures, and personal automation.

**Repository Contents:**
The collection includes skills spanning creative work (art, music, design), technical applications (web app testing, MCP server generation), and business processes (communications, branding). Document manipulation skills for DOCX, PDF, PPTX, and XLSX formats are included as source-available references showing production-level implementations.

## Implementation Options

Users can access these skills through:
- **Claude Code**: Register the repository as a marketplace plugin and install skill sets
- **Claude.ai**: Pre-built skills are available to paid subscribers; custom skills can be uploaded
- **Claude API**: Deploy skills programmatically through the Skills API

## Creating Skills

The skill structure requires minimal setup—just a folder with a `SKILL.md` file. The file needs YAML frontmatter specifying a `name` (unique identifier) and `description` (functionality overview), followed by markdown instructions, examples, and guidelines that Claude follows.

## Important Disclaimers

"These skills are provided for demonstration and educational purposes only." Actual Claude implementations may differ from these examples, and thorough testing is recommended before production deployment.

# Knowledge Work Plugins - Complete README

## Overview

This documentation presents 11 open-source plugins designed for Claude Cowork and Claude Code. These tools transform Claude into specialized assistants for specific professional roles.

## Core Concept

The plugins operate on a fundamental principle: "tell Claude how you like work done, which tools and data to pull from, how to handle critical workflows." This customization approach enables teams to align Claude's capabilities with their specific processes and terminology.

## Available Plugins

The marketplace includes plugins for:

- **Productivity** — Task and calendar management via Slack, Notion, Asana, and other platforms
- **Sales** — Prospect research and pipeline management through HubSpot, Close, and related tools
- **Customer Support** — Ticket triage and knowledge base development with Intercom and Jira
- **Product Management** — Roadmap planning using Figma, Linear, and analytics platforms
- **Marketing** — Campaign planning and brand enforcement via Canva and HubSpot
- **Legal** — Contract review and compliance tracking through Box and Microsoft 365
- **Finance** — Account reconciliation using Snowflake and BigQuery
- **Data** — SQL querying and dashboard building
- **Enterprise Search** — Cross-platform document discovery
- **Bio Research** — Life sciences tools including PubMed and Benchling
- **Plugin Management** — Custom plugin creation and modification

## Technical Architecture

Each plugin follows a consistent structure with manifest files, MCP connections, explicit slash commands, and encoded domain skills that activate automatically when relevant.

## Customization Philosophy

Users can modify connectors, embed company context, adjust workflows, and create entirely new plugins tailored to their organizational needs.

# Claude Code Migration Kit - Complete README

I've provided the full webpage content you requested above. Here are the key sections:

**Overview:** This is a starter kit for large-scale language migrations using Claude Code, focusing on "structure-preserving migrations" where architecture remains unchanged but the programming language switches.

**Quick Start:** The process involves cloning the kit, copying operating manuals, optionally installing skills, and working through six sequential steps with prompts and templates.

**Core Principle:** As stated in the documentation, "you don't fix the code — you fix the process that produced the code."

**The Six Steps:**
1. Create dependency maps and translation rules
2. Stress-test rules through dual-translation and pilot runs
3. Translate everything using mechanical queues
4. Compile and fix errors systematically
5. Run basic functionality tests
6. Match behavior against original code using test suites

**Key Resources Included:**
- Eight paste-ready prompts (feasibility through post-parity)
- Templates for ruleooks and inventory tracking
- Scripts for dependency mapping and queue management
- Fixtures and example runs
- Operating manual (CLAUDE.md)

**Important Notes:** The kit defaults to structure-preserving migrations. For redesigns, the rulebook becomes a design document and the bakeoff validation changes. The process works at any API rate limit, though production-scale ports consume "billions of input tokens inside two weeks."

**License:** Apache-2.0

# ant — Claude Platform CLI Complete README

## Overview
The `ant` CLI is the official command-line tool for the Claude Platform API, enabling users to interact with Claude directly from their terminal for messaging, agent management, session handling, and file uploads.

## Installation Options

**Homebrew:**
```sh
brew install anthropics/tap/ant
```

**From Source (Go 1.22+):**
```sh
go install 'github.com/anthropics/anthropic-cli/cmd/ant@latest'
```

Users must add `$(go env GOPATH)/bin` to their PATH if needed.

## Authentication

Users can authenticate through:
- `ant auth login` using Claude Console credentials
- Setting the `ANTHROPIC_API_KEY` environment variable

## Command Structure

The CLI uses resource-based commands with nested resources separated by colons: `ant <resource>[:<subresource>] <command> [flags...]`

Example commands include listing models, retrieving model details, creating messages, sending files, and managing beta resources like agents and sessions.

## Key Features

- "Relaxed JSON or YAML" syntax for flags with unquoted keys
- Interactive response explorer in terminals
- Field extraction via `--transform` with `jq`-style syntax
- File uploads using `@path` notation
- Support for images and multi-modal content

## System Requirements

Compatible with macOS, Linux, and Windows.

## Licensing

# Claude Agent SDK for Python - Complete README

The documentation describes a Python SDK enabling developers to build agents with Claude Code. Installation requires Python 3.10+ via `pip install claude-agent-sdk`.

## Core Features

The SDK offers two primary interfaces. The `query()` function provides simple async queries returning message iterators. The `ClaudeSDKClient` enables bidirectional conversations with additional capabilities including custom tools and hooks.

## Key Capabilities

**Tool Management**: Claude accesses the full Claude Code toolset by default. The `allowed_tools` parameter creates an allowlist for auto-approval, while `disallowed_tools` blocks specific tools. The documentation notes: "listed tools are auto-approved, and unlisted tools fall through to permission_mode."

**Custom Tools**: Developers can define tools as Python functions using the `@tool` decorator, implemented as in-process MCP servers. This approach eliminates subprocess management overhead compared to external MCP servers.

**Hooks**: Application-level functions intercept agent loop events for deterministic processing and automated feedback, with examples provided for pre-tool-use validation.

**Working Directory**: Configuration supports specifying project paths via the `cwd` parameter.

## Configuration and Error Handling

`ClaudeAgentOptions` configures system prompts, turn limits, MCP servers, and permission modes. The SDK provides specific error types including `CLINotFoundError`, `CLIConnectionError`, `ProcessError`, and `CLIJSONDecodeError`.

## Development and Deployment

The package includes bundled Claude Code CLI with customizable paths. Build scripts support platform-specific wheels, and GitHub Actions workflows automate PyPI publishing. Release procedures involve triggering workflows with version and CLI version inputs.

## Legal Framework

Usage is "governed by Anthropic's Commercial Terms of Service," including when powering customer-facing products, except where specific dependencies carry different licenses.

# Claude Tag Plugins - Complete README

The repository provides integrations connecting Claude agents to 18+ SaaS platforms. Each plugin operates independently, allowing workspaces to activate only needed services.

## Core Plugin Offerings

The collection includes task management (Asana, Linear), data warehousing (BigQuery, Redshift, Snowflake), incident response (PagerDuty, Sentry), and enterprise tools (Jira, Confluence, Salesforce, HubSpot). Additional capabilities span monitoring (Datadog, Grafana), documentation (Notion), and file collaboration (Google Drive).

## Installation Pattern

Users add the marketplace via Claude Tag, then selectively install individual service plugins. Skills activate automatically when contextually relevant to agent operations.

## Structural Consistency

"Each service plugin follows the same structure" with a plugin manifest, skill documentation, reference materials, and executable helper scripts where applicable.

## Authentication Framework

The system absterts credential handling to the runtime environment rather than embedding auth instructions. Environment variables like `$DD_API_KEY` maintain request formatting while actual secrets inject during execution.

## Safety Protocols

Scripts employ bearer token authorization headers. Outside credential-injecting environments, requests fail safely with 401 responses rather than exposing placeholder values. The guidance emphasizes never committing real credentials and using runtime secret injection instead.

The project maintains active status under Anthropic with Apache 2.0 licensing, plus third-party MIT-licensed JavaScript libraries bundled in the data visualization plugin.

# claude-desktop-buddy README

This project enables developers to build hardware devices that connect to Claude via Bluetooth Low Energy (BLE). The firmware targets ESP32 boards, specifically the M5StickC Plus, creating an interactive "desk pet" that responds to Claude's activity.

## Core Functionality

The device displays permission prompts, recent messages, and interaction states. According to the documentation, "developers and makers can build hardware that displays permission prompts, recent messages, and other interactions."

## Hardware & Installation

The firmware uses the Arduino framework and depends on the M5StickC Plus library. Installation requires PlatformIO Core, with commands like `pio run -t upload` to flash the device.

## Pairing Process

Users must enable developer mode in Claude, then access **Developer → Open Hardware Buddy…** to establish connection. The bridge automatically reconnects when both devices are awake.

## Control Scheme

The device features three buttons controlling different functions depending on the current screen state (normal, pet mode, info, or approval screens). Button A advances screens, Button B scrolls, and holding Button A opens the menu.

## Pet System

The firmware includes eighteen ASCII-based pets with seven animations each. Users can also upload custom GIF character packs (up to 1.8MB) through drag-and-drop functionality in the Hardware Buddy window.

## Seven States

The pet responds to seven distinct states: sleep (disconnected), idle (connected), busy (active sessions), attention (pending approvals), celebrate (achievement milestones), dizzy (physical shake), and heart (quick approvals).

## Developer Access

This BLE API requires developer mode activation and serves the maker community specifically—it's "not an officially supported product feature."

# Complete README Content

I've reviewed the web page content you provided. Here is the full README text from the Defending Code Reference Harness repository:

The document outlines an open-source reference implementation for autonomous vulnerability discovery and remediation using Claude. Key sections include:

**Overview**: This is "a reference implementation for autonomous vulnerability discovery and remediation with Claude," not a maintained product. Anthropic offers Claude Security as a managed alternative for scanning repositories across multiple projects.

**Main Components**: The repository contains interactive Claude Code skills for scoping, scanning, triage, and patching work; an autonomous reference pipeline (recon → find → verify → report → patch) configured for C/C++ memory vulnerabilities; and detection & response tools for threat hunting in logs.

**Security Notes**: Interactive skills only read/write files and run safely unsandboxed. Autonomous pipelines execute target code and require gVisor sandboxing unless explicitly overridden. The setup requires running `scripts/setup_sandbox.sh` once, then invoking via `bin/vp-sandboxed`.

**Five-Step Ramp-Up Plan**:
- Day 1: Build threat model and run static scan with triage
- Day 2: Execute reference pipeline on C/C++ library
- Days 3-5: Customize pipeline for your target
- Week 2: Scale autonomous scanning, triage, and patching
- Optional: Hunt attackers in logs using detection & response tools

**Customization Path**: The harness is portable by answering three questions: what signals a finding, what constitutes proof of concept, and how is the target built/run.

**Post-Launch Focus Areas**: Successful teams typically review internal repos and dependencies, establish dedicated scanning infrastructure, integrate scanning into development workflows, and experiment with model configurations.
