• CLAUDE.md Plan mode code rabit or any other code review tool Claude PRO MAX subscription or Codex

• One thing that's worked well for me is scattering agents.md files throughout the repo and loading the relevant ones based on what the agent is touching. It keeps architecture notes and local conventions close to the code, which works better than one giant project document.

• Use agent mode in vscode with sonnet or Claude code terminals and do an architectural decision record doc for each setup areas and all technical decisions. Ask more of your agent about your processes. Use context to your advantage and think not just of the product but also the docs as being the foundational context for the work.

• My approach to work on new project

  - Setup proper CLAUDE.md or AGENTS.md

  - Use cmux or conductor to manage multiple instances of Claude Code

  When working of some business feature I always ask AI to summarize every conversation in following format: problem, brief solution, where change were made. And I store it in the repo under "journal" folder where each file has "2026-06-08-add-offile-firts-support.md"

  Also for me personally having separate repository with some boilerplate code become a huge booster of productivity.

  Usually inside this boilerplate repo I have:

  - Descriptions of desired project structure, so every project follows the same structure I personally like

  - Some CI/CD templates, in my case: build docker container, push into github registry, deploy to my bare bone VM

  - Authentication + third parties integration

  - Custom exceptions and middleware to handle those exceptions

  - And more
