CleanSlate IDE with built-in agent manager for multi-agent coding workflows
CleanSlate is an IDE that integrates an agent manager directly, allowing developers to create, manage, and switch between multiple coding agents without leaving the editor. It solves the friction of toggling between separate agent management tools and the IDE, enabling seamless context preservation and multi-agent orchestration for developers working with LLM-powered coding agents.
Confessor: Analyzes Claude Code transcripts to show what the AI agent did on your computer
Confessor is an open-source tool that reads the JSONL log files Claude Code leaves on disk and generates a human-readable report of every action the AI agent performed, including tool calls, file reads, and shell commands. It helps developers understand and audit the behavior of AI coding agents on their machines.
Passation: Resume interrupted AI coding sessions seamlessly
Passation is a passive Python script that generates a handoff document when a Claude Code or Codex CLI session is interrupted by usage limits. It captures the current state, unfinished tasks, and plans so a new agent can continue without losing context. This solves the problem of coding sessions dying mid-task and the risk of switching agents.
