USE CASE · ONBOARDING
Received an unfamiliar codebase? Do not read files in order.
Project Brain lets AI map the codebase first, then focus on entry points, modules, dependencies and important business flows. Useful for handoffs, legacy projects and joining a new team.

1. Read-only
Add the repository root and leave write/task off when you only need understanding.
2. Ask for a map
Entry points, modules, data flow, auth, config, tests and deployment paths.
3. Create documentation
Optionally grant a separate Output project so AI can create architecture.md/onboarding.md.
Use ChatCode with project legacy-erp. Read-only. Help a new developer understand it in 30 minutes: architecture, entry points, major modules, auth flow, database, tests, build/deploy, and the first 10 files to read. Cite evidence by file/symbol.Create onboarding.md in project AI-Output from the analysis above. Do not modify legacy-erp.
