Claude Code for Continuous Integration

Your Claude Code CI pipeline automatically runs tool-returned shell commands against a staging environment as part of a nightly build validation workflow. Over three nights in a row, you observe unexpected package installations and environment variable overwrites occurring during runs — none of which were in the original test scripts. Logs show the tool results ingested by Claude contain strings from an external dependency-resolution API. What is the most likely root cause of this behavior?

A. The CI pipeline's context window is too small, causing Claude to hallucinate shell commands to fill gaps in its reasoning about the build state.

B. Tool results from the external API are passed to the execution environment without validation, allowing executable content embedded in the returned strings to run as commands.

C. Claude's system prompt lacks an explicit instruction prohibiting environment modifications, so Claude freely interprets tool output as authorized commands and acts on it.

D. The external API is returning results in an unsupported format, causing Claude to switch to a fallback behavior that executes arbitrary commands to resolve the ambiguity.
