New post: how I make my 20€/month Claude Pro plan last longer in Claude Code. The main session runs Opus 5.5 at medium effort and makes the decisions. A Sonnet 5.5 subagent writes the code, and Haiku 5.5 subagents scope the task and open the pull request. Compared with 24 Opus-only sessions, each PR now costs about 40% less, even if the PRs are bigger. My agent files, https://claude.md and the numbers are all in the post. https://www.andreagrandi.it/posts/claude-code-subagents-to-save-usage/ #ClaudeCode #AI #LLM #CodingAgents
