High-performance Rust-based statusline for Claude Code with persistent stats tracking, progress bars, and optional cloud sync. Features SQLite-first persistence, git integration, context progress bars, burn rate calculation, XDG-compliant with theme support (dark/light, NO_COLOR).
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.
Honeycomb's OpenTelemetry-native observability platform: a high-cardinality event store ideal for tracing LLM pipelines and debugging slow agent traces.
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.
Baserun captures LLM traces via a lightweight decorator-based SDK and provides a dashboard for debugging prompt chains, testing variants, and measuring quality.
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.
Log every file mutation to CSV for demo prep. Records timestamp, tool, file path, action, and details for Edit, MultiEdit, Write, and Bash operations. Output: .claude/critical_log_changes.csv
Change Logger Hook Logs every file mutation (Edit, Write, Bash) to a CSV file for demo prep and session review. Output: .claude/critical_log_changes.csv
Real-time browser visualization of Claude Code's context window and subagent/tool execution as a git-graph timeline. Opens http://localhost:7878 on SessionStart with a vertical timeline (most recent on top), one column per agent (main + subagents branching from their Task tool call). Tool calls are color-coded by type (Read=green, Edit/Write=orange, Bash=red, Grep/Glob=cyan, Task=purple, Web=yellow, MCP=gray). Right sidebar shows context-window usage (tokens/200K) with cache_read/cache_creation/input/output breakdown plus per-subagent mini-context. Reads ~/.claude/projects/<encoded-cwd>/<session_id>.jsonl directly — no data replication, no network calls. Pure stdlib Python, zero pip dependencies. Persistent daemon HTTP server on port 7878 (auto-fallback 7879-7888 if busy; override with CONTEXT_TIMELINE_PORT env var). Watchdog auto-shutdown after 1h of inactivity. Disable browser auto-open with CONTEXT_TIMELINE_NO_BROWSER=1. Manual shutdown: python3 .claude/hooks/context-timeline.py --shutdown
