Claude Second Opinion

Delegate a task to Claude Code for an independent review or second opinion.

Input

<task> $ARGUMENTS </task>

If no task is provided, ask the user what they want Claude to review.

How to Use

Run Claude in non-interactive print mode from the current working directory. Prefer a read-only tool set:

claude -p \
  --permission-mode dontAsk \
  --allowedTools Read,Grep,Glob,LS \
  --add-dir "<current working directory>" \
  "<prompt>"

If the Claude CLI is not installed or is not authenticated, report that blocker and include the command output.

Prompt Construction

Build a self-contained prompt for Claude that includes:

1. Context: The repo path, what project this is, and what folder/files are relevant
2. The task: What you want Claude to do (review, validate, suggest, etc.)
3. Constraints: Tell it to only read files, not modify anything

Keep it unbiased. Do not include your own conclusions or preferred answer. Present the problem neutrally so Claude forms its own opinion.

Be specific about files. Tell Claude exactly which files to read — it has access to the repo but needs direction.

Example

claude -p \
  --permission-mode dontAsk \
  --allowedTools Read,Grep,Glob,LS \
  --add-dir "/path/to/project" \
  "Review the file at src/config.py. Is the retry logic correct? Read the file and give your assessment. Do NOT modify any files."

Troubleshooting

• Authentication: If Claude exits with an auth error, ask the user to run claude auth or configure the required Claude credentials before retrying.
• Tool restrictions: If Claude cannot read the requested files, retry with a narrower prompt and the same read-only tools. Do not remove read-only restrictions unless the user explicitly approves.
• Output truncation: Claude may produce a long review. Keep prompts focused and ask specific questions rather than open-ended reviews.
• Session state: Use -p for a fresh non-interactive answer. Do not use --continue or --resume unless the user specifically asks to continue an existing Claude session.

After Claude Responds

1. Report the Claude response to the user
2. Note where you agree or disagree with Claude's assessment
3. Let the user decide how to proceed
