If the current branch name corresponds to a linear task:

1. Run linctl issue view to fetch the full details of the current issue based on the branch name
2. Read the title, description, and any other relevant content from the ticket output
3. Run linctl issue update $issueID --state "In Progress" to update the issue to 'In Progress' state
4. Based on the ticket content, create a comprehensive plan using the TodoWrite tool to track all the work needed to complete this issue
5. Do steps 1-3 silently without mentioning them unless there's an error
6. After creating the plan, present it to the user and ask if they'd like to proceed or adjust the plan

If we're not on a branch corresponding to a linear task, like main, do nothing.
