migrate-discussion — move items between Discussions and Issues

Move a topic to the tracker where it belongs: a discussion that turned into a concrete bug/task should become an Issue; an issue that's really a question, idea, or support request should become a Discussion. Migration is a judgement call — the "when helpful" part matters as much as the mechanics.

When this fires

• User says "convert this issue to a discussion", "move #N to Discussions"
• User says "this discussion is really a bug — make it an issue", "open an issue from discussion #N"
• While triaging: an issue is generating open-ended debate with no actionable scope, or a discussion has converged on a concrete task someone will do

Don't migrate just because a thread is long. Migrate only when the item is clearly in the wrong tracker.

Decide first — is a move actually warranted?

Move it discussion → issue when…	Move it issue → discussion when…
It's a concrete, reproducible bug	It's an open-ended question or support request
It's an actionable task with a clear "done"	It's brainstorming / a feature idea with no decision
Maintainers have decided to act on it	It needs community input before any work
It needs an assignee, label, milestone, or board	It has no actionable scope and no owner

Leave it where it is when it's borderline, when both trackers fit, or when the thread is active and a move would disrupt it. When unsure, ask the user — don't migrate on a hunch.

Prefer GitHub's native convert feature

GitHub has built-in one-click conversions, and they're the best path because they preserve the original author, the full comment thread, and post an automatic cross-reference:

• Issue → Discussion: on the issue, use the "Convert to discussion" menu item (issue sidebar / ... menu), pick a category.
• Discussion → Issue: on the discussion, use "Create issue from discussion" (discussion ... menu).

There is no GraphQL mutation or gh subcommand for either conversion — they are UI-only. So when you (or the user) can reach the web UI, that's the move: point the user at the button, or walk them through it, and you're done.

Use the recreate procedure below only when the native UI path isn't usable (scripted/headless context, or the user explicitly wants it rebuilt).

Fallback — recreate and cross-link

When you can't use the native convert feature, create the new item by hand, preserve attribution, cross-link both ways, and close the original with a pointer. Get the user's approval on the drafted new item before creating it — this is outward-facing and hard to reverse.

Discussion → Issue

1. Read the source discussion (see the discussions skill's read query) to capture its title, body, author, URL, and key comments.

2. Create the issue, quoting the original and linking back so authorship and context aren't lost:

   gh issue create \
     --title '<original title>' \
     --label P2 \
     --body 'Migrated from discussion <url> (opened by @<author>).
   
   <original body, quoted>
   
   Key points from the discussion thread:
   - @<login>: <summary>'   # CREATE_ISSUE
   

   In a remote/web session, use mcp__github__issue_write (method: create) with the same body instead of gh. Set the priority (P2 is the default) per issue-first; the issue quotes human content, so it takes no ai-authored or model label. Where the repo has no P2 label yet, create it first (label-agent-filed-issues).

3. Comment on the discussion pointing at the new issue, then close it:

   gh api graphql -f discussionId='<discussion-id>' -f body='Moved to <issue-url> to track the actionable work.
   
   _Posted by Claude Code (AI agent) --- not written by a human._' -f query='
     mutation($discussionId: ID!, $body: String!) {
       addDiscussionComment(input: {discussionId: $discussionId, body: $body}) {
         comment { url }
       }
     }'   # COMMENT_DISCUSSION
   
   gh api graphql -f discussionId='<discussion-id>' -f query='
     mutation($discussionId: ID!) {
       closeDiscussion(input: {discussionId: $discussionId, reason: OUTDATED}) {
         discussion { url closed }
       }
     }'   # CLOSE_DISCUSSION
   

   closeDiscussion reasons are RESOLVED, OUTDATED, or DUPLICATE; use OUTDATED for a plain move.

Issue → Discussion

1. Read the source issue (gh issue view <N> — VIEW_ISSUE — or mcp__github__issue_read) for its title, body, author, URL, and comments.

2. Look up the repository node ID and the target category ID (only certain categories exist per repo):

   gh api graphql -f owner='<owner>' -f repo='<repo>' -f query='
     query($owner: String!, $repo: String!) {
       repository(owner: $owner, name: $repo) {
         id
         discussionCategories(first: 20) { nodes { id name isAnswerable } }
       }
     }'
   

3. Create the discussion, quoting the original and linking back:

   gh api graphql -f repositoryId='<repo-id>' -f categoryId='<category-id>' -f title='<original title>' -f body='Migrated from issue <url> (opened by @<author>).
   
   <original body, quoted>' -f query='
     mutation($repositoryId: ID!, $categoryId: ID!, $title: String!, $body: String!) {
       createDiscussion(input: {repositoryId: $repositoryId, categoryId: $categoryId, title: $title, body: $body}) {
         discussion { number url }
       }
     }'   # CREATE_DISCUSSION
   

4. Comment on the issue pointing at the new discussion, then close the issue as not planned:

   gh issue comment <N> --body 'Moved to <discussion-url> — this is better suited to Discussions.
   
   _Posted by Claude Code (AI agent) --- not written by a human._'   # COMMENT_ISSUE
   gh issue close <N> --reason 'not planned'   # CLOSE_ISSUE
   

   In a remote/web session, use mcp__github__add_issue_comment and mcp__github__issue_write (method: update, state: closed, state_reason: not_planned).

Report back

Give the user both links (old and new) as clickable markdown links, say which direction the migration went, and confirm the original was closed with a pointer.

Relationship to other skills

• discussions — reads/answers discussion topics; this skill reuses its read query and hands topics back to it when a reply (not a move) is the right response.
• defer-issue — files a fresh follow-up issue for out-of-scope work; this skill moves an existing item between trackers.
• sup — routes a report to the right destination (issue vs Discussions) on an upstream repo; same tracker-fit judgement, other people's repo.

Anti-patterns

• ❌ Hand-rebuilding when the native "Convert to discussion" / "Create issue from discussion" button would do it — the native path keeps authorship, the thread, and cross-links; the fallback loses per-comment authorship.
• ❌ Migrating without cross-linking both ways — always leave a pointer on the original and reference the original in the new item.
• ❌ Closing the original before the new item exists — create first, link, then close, so nothing is orphaned.
• ❌ Creating the new item without the user's approval — outward-facing and hard to reverse.
• ❌ Migrating a borderline item on a hunch — when both trackers fit, leave it and ask.
