Preflight Checklist

  • I have searched existing issues and this hasn't been reported yet
  • This is a single bug report (please file separate reports for different bugs)
  • I am using the latest version of Claude Code

What's Wrong?

Please added logging for when claude tries to execute hooks or commands like otelHeadersHelper. I'm pulling my hair out trying to troubleshoot this.

What Should Happen?

I should have a log that shows what hooks or otelHeadersHelper commands claude is attempting to execute.

Error Messages/Logs

The problem is there are no errors or logs.

Steps to Reproduce

Claude isnt calling any of my scripts and I see no logs anywhere.

  "otelHeadersHelper":"/bin/myscript.sh",
  "hooks":{
    "SessionStart":[
      {
        "hooks":[{
          "type":"command",
          "command": "export OTEL_EXPORTER_OTLP_HEADERS=\"Authorization=Bearer $(my command)\""
        }]
      }
    ],
    "UserPromptSubmit":[
      {
        "hooks":[{
          "type":"command",
          "command": "export OTEL_EXPORTER_OTLP_HEADERS=\"Authorization=Bearer $(my command)\""
        }]
      }
    ],
     "PreToolUse":[
      {
        "hooks":[{
          "type":"command",
          "command": "export OTEL_EXPORTER_OTLP_HEADERS=\"Authorization=Bearer $(my command)\""
        }]
      }
    ]

TL;DR

Adding logging for hook and command execution in Claude Code may require modifying the configuration to include logging options for the otelHeadersHelper and hooks.

Guidance

  • Review the Claude Code documentation to see if there are any built-in logging options for hooks and commands that can be enabled.
  • Check if the otelHeadersHelper and hooks are correctly configured and if the scripts are executable.
  • Consider adding custom logging statements to the scripts executed by the hooks to verify if they are being called.
  • Verify that the hooks and otelHeadersHelper configurations are correctly formatted and match the expected input for Claude Code.

Example

No code example is provided as the issue lacks specific details about the implementation.

Notes

The issue lacks information about the exact configuration and implementation of the otelHeadersHelper and hooks, making it difficult to provide a precise solution. Additionally, the absence of error messages or logs makes it challenging to diagnose the issue.

Recommendation

Apply workaround: Add custom logging statements to the scripts executed by the hooks to verify if they are being called, as the built-in logging options for Claude Code are unclear.
