PostToolUse hooks cannot inject stdout directly into Claude context - only SessionStart and UserPromptSubmit can. The fix is to use JSON output with additionalContext field: {hookSpecificOutput: {hookEventName: 'PostToolUse', additionalContext: 'your message'}}. Also discovered tool_response (not tool_output) is the correct field name, and exitCode doesn't exist - must infer success from stdout patterns.
