A lightweight Python SDK with a clean API and good documentation; simplifies the process of writing hooks and integrating them into your codebase, providing a nice abstraction over the JSON configuration files.
A Laravel-inspired PHP SDK for building Claude Code hook responses with a clean, fluent API. This SDK makes it easy to create structured JSON responses for Claude Code hooks using an expressive, chainable interface.
Prompt injection scanner for Claude Code hooks. Scans tool inputs and outputs for injection attacks, secrets, and data exfiltration attempts. In early development when it was listed.
Claude outputs American spellings by default, which can have an impact on: professional credibility, compliance, documentation, and more. Britfix converts to British English, with a Claude Code hook for automatic conversion as files are written. Context-aware: handles code files intelligently by only converting comments and docstrings, never identifiers or string literals.
Use to give an agent a queryable wiki knowledge base when memory should be a navigable knowledge graph, not just a flat log: ingest files, folders, and URLs into a linked vault, then search or ask it in natural language.
Use to put a number on harness quality: run an agent harness against a task set and get a score, so harness changes are validated by evidence. It is the eval backbone of a self-improving loop.
Automatically loads AGENTS.md configuration file content at session start to ensure Claude Code follows project-specific agent behavior. Only loads if AGENTS.md exists, otherwise passes empty context. Supports the universal AGENTS.md standard for cross-platform AI assistant compatibility.
AI-powered bash command security guard. Before any Bash command runs, a lightweight Claude subagent evaluates it for destructive or irreversible patterns — recursive deletes, force pushes to protected branches, database drops, and credential exposure — and blocks execution with a clear explanation if flagged. Uses PreToolUse with type:agent, which is the only hook pattern that can block tool execution via AI reasoning.
Create automatic backup of files before any Edit operation for safety. This hook creates a timestamped backup copy (filename.backup.timestamp) of any existing file before Claude modifies it. Provides a safety net to recover previous versions if needed. Only backs up existing files, includes error suppression to handle edge cases gracefully.
