Onboard

When you land in an unfamiliar codebase, this spawns a subagent that explores the project structure, detects the tech stack, and creates a YAML continuity ledger in your project's handoff directory. It's smart about not dumping thousands of lines into your main context. Instead, it uses tools like tldr and find to map the terrain, asks you what you're trying to accomplish, then writes a structured handoff with key files, architecture notes, and suggested next steps. The handoff loads automatically in future sessions, so you're not starting from zero every time. It's specifically for brownfield projects where you need to get oriented fast without manually reading through everything.
