Remix supersede-pr

Safely replace one GitHub pull request with another. Use when a user says a PR supersedes/replaces an older PR, asks to auto-close a superseded PR, or needs guaranteed closure behavior after merge. This skill explicitly closes the superseded PR with gh CLI and verifies final PR states instead of relying on closing keywords.

Supersede PR

Overview

Use this skill to handle PR supersession end-to-end. Do not rely on

Closes #<number>

to close another PR. GitHub closing keywords close issues, not pull requests.

Workflow

Identify PR numbers and target repo.

Capture
```
old_pr
```
(the superseded PR) and
```
new_pr
```
(the replacement PR).

Resolve the repo with

gh repo view --json nameWithOwner -q .nameWithOwner

when not provided.

Create or update the replacement PR first.

Open/push the replacement branch.
Open the new PR.
Include a traceable link in the PR body such as
```
Supersedes #<old_pr>
```
.

Close the superseded PR explicitly.

Run:

scripts/close_superseded_pr.ts <old_pr> <new_pr>

This adds a comment (
```
Superseded by #<new_pr>.
```
) and closes the old PR.

Verify states.

Confirm the superseded PR is closed:

gh pr view <old_pr> --json state,url

Confirm the replacement PR status/checks:

gh pr checks <new_pr>

Rules

Do not use
```
Closes #<old_pr>
```
when
```
<old_pr>
```
is a pull request.

Use
```
Closes/Fixes
```
only for issues.
Use
```
Supersedes #<old_pr>
```
or
```
Refs #<old_pr>
```
for PR-to-PR linkage.

Prefer explicit closure over implied automation.

Always run the close command when the user asks to supersede a PR.
Treat closure as incomplete until
```
gh pr view <old_pr>
```
returns
```
CLOSED
```
.

Script

Use the bundled script for deterministic closure:

```
scripts/close_superseded_pr.ts
```
