Hi everyone! I’ve been using Claude Code since the beginning of the year to build a Python-based test bench from scratch. While I’m impressed with the code quality, I’ve recently hit a wall with usage consumption that I can’t quite explain. I’m curious if it’s my workflow or something else. I started by building the foundation with Opus 4.5 and my approach was: Use plan mode to create 15+ phases into dedicated Markdown files. The phases were intentionally small to avoid context rot. I try to never exceed more than 50% of context usage. Create a new session for the implementation of each phase (still with Opus), verify, test, commit and go to next phase I also kept a dedicated Markdown file to track the progression The implementation went great but I did have to switch from Pro plan to Max x5 plan because I was hitting the limit after 2 to 3 phase implementations. With the upgrade, I never hit the limit - in fact, I rarely even reached 50% usage, even during heavy development days. Naturally, I started to add more features in the project, with the same approach, and it was working perfectly, but recently things have changed. A day before Opus 4.6 release, I noticed usage limits increasing faster than usual. And now with Opus 4.6 it is even worse, I sometimes reach 50% in one hour. Have you also noticed a usage limit increase? I know there is a bug opened on Github about this exact problem, but not everybody seems to be impacted. How do you proceed when adding a feature to your codebase? Do you use a similar approach to mine (Plan then implement)? Should I plan with Opus and implement with Sonnet, or even Haiku? I’d love to hear how you’re managing your sessions to keep usage under control! Additional info about my project Small codebase (~14k LOC, including 10k for unit tests). I maintain a CLAUDE file (150 lines) for architecture and project standards (ruff, conventional commits, etc.). I do not use MCPs, skills, agents or plugins. I plan with Opus and write code with Opus. With Opus 4.6, I usually set the effort to high when planing and medium when coding. Thank you :) P.S: edited to add more info about the project and setup. submitted by /u/Blubst3r
