Document Service

Activate this when you inherit an undocumented codebase and need to understand what it actually does. It generates structured technical documentation with source-of-truth citations, tracing every claim back to specific files and line numbers. The workflow is autonomous after you point it at a directory. It maps architecture, traces request flows end to end, deep dives complex logic, and surfaces implicit knowledge like hardcoded values and unhandled failure modes. Optimized for AWS workloads with CDK, CloudFormation, and Terraform parsing, but works on any codebase. Think of it as the "it's 3am and this is broken, where do I look" analysis your team never had time to write.
