Claude Code for Continuous Integration

Your CI pipeline uses Claude Code to auto-implement utility functions flagged by failing tests. Over the past two weeks, 34% of auto-implemented functions pass Claude's internal review but fail the actual test suite when the PR runs — requiring a developer to manually intervene before merge. Logs show Claude is generating plausible implementations without any concrete pass/fail criteria to evaluate against. What change would most effectively reduce the implementation failure rate?

A. Add a system prompt instruction telling Claude to be more rigorous and to carefully double-check its implementations before marking them complete.

B. Provide concrete test cases inline with each request — exact inputs paired with expected outputs — and instruct Claude to run them after implementing.

C. Increase the token budget for each implementation task so Claude has additional room to reason through edge cases before producing its final output.

D. Add a second Claude Code pass that reviews the first implementation and flags any logic it considers likely to fail in the test suite.
