Safely replace one GitHub pull request with another. An agent skill from remix-run/remix.

  • Runs TypeScript scripts from its folder; calls gh
  • Asks to auto-close a superseded PR

What it does

Supersede PR is an agent skill from remix-run/remix. 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 Use when a user says a PR supersedes/replaces an older PR, asks to auto-close a superseded PR, or needs guaranteed closure behavior after merge. This skill explicitly closes the superseded PR with gh CLI and verifies final PR states instead of relying on closing keywords.

Its SKILL.md is about 460 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including scripts (for example `agents/openai.yaml`, `scripts/close_superseded_pr.ts` and `tsconfig.json`).

It sits in Development. It works with GitHub. The repository describes itself as: The fully-stacked web framework. The licence is MIT.

When your agent uses it

  • A user says a PR supersedes/replaces an older PR
  • Asks to auto-close a superseded PR
  • Needs guaranteed closure behavior after merge

Example prompts

  • “/supersede-pr”

Requirements

  • Node.js

What it can do on your machine

Read from SKILL.md and the folder at commit 3c25f7a. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (TypeScript), which the agent can run.

    Shell commands in SKILL.md call:

    • gh

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use gh, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Supersede PR loads about 456 tokens when it runs. Until then it costs about 85 tokens; SKILL.md has 189 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~85
When it runs · the whole SKILL.md, loaded when a task matches
~456

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

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.

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

  1. 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.
  1. 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>.
  1. Close the superseded PR explicitly.
  • Run:
bash
scripts/close_superseded_pr.ts <old_pr> <new_pr>
  • This adds a comment (Superseded by #<new_pr>.) and closes the old PR.
  1. Verify states.
  • Confirm the superseded PR is closed:
bash
gh pr view <old_pr> --json state,url
  • Confirm the replacement PR status/checks:
bash
gh pr checks <new_pr>

Rules

  1. 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.
  1. 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

© remix-run, MIT. Rendered from Markdown: HTML in the file is shown as text, images as links, and headings moved down two levels. Raw file

Files

SKILL.md and 3 other files (scripts) in .agents/skills/supersede-pr of remix-run/remix.

  • SKILL.md
  • agents/openai.yaml
  • scripts/close_superseded_pr.ts
  • tsconfig.json
