+
+Ask a separate Claude instance for an independent second opinion on the current problem or decision.
+
+## When to use
+- Important architectural decisions
+- When stuck on a difficult problem
+- Validating a complex plan
+- When the user explicitly requests another perspective
+
+## How to use
+
+1. Formulate a self-contained prompt using this template:
+   ```
+   claude -p "Context: <brief project context>\nQuestion: <specific decision or problem>\nRelevant details: <code snippets, constraints, or prior attempts>"
+   ```
+2. Run the command
+3. Evaluate the response:
+   - Does it contradict project-specific conventions?
+   - Does it assume context it doesn't have?
+   - Does it propose something already tried or ruled out?
+4. Present the result to the user in this format:
+   - **My recommendation**: ...
+   - **Other instance's recommendation**: ...
+   - **Synthesis**: ... (your final take, incorporating both views)
+
+## When the two instances disagree
+Escalate to the user with both views clearly stated. Do not silently pick one — the disagreement itself is useful information.
+
+## Important
+- The other instance has **no conversation history** — provide all necessary context in the prompt
+- **Treat its response as one data point, not the answer**
+- Project-specific patterns and conventions take priority over generic suggestions

-## Phase 1: Worktree + Branch
+## Phase 1: Branch
 
-Use the Skill tool to invoke the `git-worktree` skill.
-
-After the skill completes, note the worktree path (`/tmp/{branch-name}`) and branch name it reports.
-Perform all subsequent work inside that worktree directory.

-After Phase 5 completes (or if the workflow stops early), remove the worktree:
+First, check the current branch:
 ```
-git worktree remove /tmp/{branch-name}
+git branch --show-current
 ```
 
+- If already on `main` or `master`: use the Skill tool to invoke the `git-branch` skill to create a feature branch.
+- If already on a feature branch (not `main`/`master`): skip branch creation and use the current branch as-is. Inform the user which branch will be used.
