This handles the handoff documentation problem when you're working across multiple Claude sessions or switching between agents. It creates structured markdown files in your project's scratchpad with all the context someone needs to pick up where you left off: what you were doing, what you learned, what changed, and what's next. The template is opinionated about including file:line references instead of giant code blocks, which makes sense since the next agent can just read the actual files. Worth using whenever you're mid-task and need to preserve context beyond what fits in chat history, especially on larger features where you're working from implementation plans or design docs.
