Generate PR Description

You are tasked with generating a comprehensive pull request description following the repository's standard template.

Steps to follow:

1. **Read the PR description template:**

   • First, check if thoughts/shared/pr_description.md exists
   • If it doesn't exist, inform the user that their humanlayer thoughts setup is incomplete and they need to create a PR description template at thoughts/shared/pr_description.md
   • Read the template carefully to understand all sections and requirements

2. **Identify the PR to describe:**

   • Check if the current branch has an associated PR: gh pr view --json url,number,title,state 2>/dev/null
   • If no PR exists for the current branch, or if on main/master, list open PRs: gh pr list --limit 10 --json number,title,headRefName,author
   • Ask the user which PR they want to describe

3. **Check for existing description:**

   • Check if thoughts/shared/prs/{number}_description.md already exists
   • If it exists, read it and inform the user you'll be updating it
   • Consider what has changed since the last description was written

4. **Gather comprehensive PR information:**

   • Get the full PR diff: gh pr diff {number}
   • If you get an error about no default remote repository, instruct the user to run gh repo set-default and select the appropriate repository
   • Get commit history: gh pr view {number} --json commits
   • Review the base branch: gh pr view {number} --json baseRefName
   • Get PR metadata: gh pr view {number} --json url,title,number,state

5. **Analyze the changes thoroughly:** (ultrathink about the code changes, their architectural implications, and potential impacts)

   • Read through the entire diff carefully
   • For context, read any files that are referenced but not shown in the diff
   • Understand the purpose and impact of each change
   • Identify user-facing changes vs internal implementation details
   • Look for breaking changes or migration requirements

6. **Handle verification requirements:**

   • Look for any checklist items in the "How to verify it" section of the template
   • For each verification step:
     • If it's a command you can run (like make check test, npm test, etc.), run it
     • If it passes, mark the checkbox as checked: - [x]
     • If it fails, keep it unchecked and note what failed: - [ ] with explanation
     • If it requires manual testing (UI interactions, external services), leave unchecked and note for user
   • Document any verification steps you couldn't complete

7. **Generate the description:**

   • Fill out each section from the template thoroughly:
     • Answer each question/section based on your analysis
     • Be specific about problems solved and changes made
     • Focus on user impact where relevant
     • Include technical details in appropriate sections
     • Write a concise changelo
