Claude Code for Continuous Integration

Your Claude Code CI pipeline runs automated PR reviews on every push to main. Each PR review session starts a fresh Claude Code instance. Engineers report that session costs have climbed to roughly $1.20 per PR review, and the /usage output shows that 60–70% of tokens are consumed before Claude reads a single changed file. Examining the setup, you find CLAUDE.md is 380 lines long and contains detailed step-by-step instructions for PR reviews, database migration workflows, and release checklist procedures — all loaded at session start. What change would most effectively reduce the per-session token cost without sacrificing review quality?

A. Trim CLAUDE.md to under 200 lines by deleting the database migration and release checklist instructions, keeping only the PR review workflow since CI sessions only perform reviews.

B. Move the PR review, database migration, and release checklist instructions out of CLAUDE.md and into separate skills, so each workflow's instructions load on-demand only when that skill is invoked.

C. Increase the token budget allocated to each CI session so the base context overhead represents a smaller proportion of total usage.

D. Split the CI pipeline into separate agent team instances — one per workflow type — so each instance only loads the instructions relevant to its assigned task.
