Write a PR description a reviewer can approve fast. An agent skill from Archive228/loopkit.

  • Opening any pull request
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Tasks that involve Pull requests

What it does

PR From Diff is an agent skill from Archive228/loopkit. Write a PR description a reviewer can approve fast. Use when opening any pull request.

Its SKILL.md is about 190 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Pull requests. The repository describes itself as: 33 battle-tested skills + minimal .claude harness for any coding agent (Claude Code, Cursor, Codex, Gemini CLI). The licence is MIT.

When your agent uses it

  • Opening any pull request
  • Tasks that involve Pull requests

Example prompts

  • “/pr-from-diff”

What it can do on your machine

Read from SKILL.md and the folder at commit 5ae033e. 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

    No scripts in the folder and no shell commands in SKILL.md.

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

  • Network

    No URLs in SKILL.md.

    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

PR From Diff loads about 188 tokens when it runs. Until then it costs about 25 tokens; SKILL.md has 87 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~25
When it runs · the whole SKILL.md, loaded when a task matches
~188

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); files beside SKILL.md are not scanned.

PR from Diff

A reviewer should understand the change without reading every line. Structure:

  • What & why — the problem and the approach, 2-3 sentences.
  • Changes — bullet the meaningful ones (skip noise like formatting).
  • How to verify — the exact steps/commands the reviewer runs to confirm it works.
  • Risks / out of scope — what could break, what you deliberately didn't do.
  • Screenshots for UI. Flag any decision the reviewer should weigh in on. Keep the PR small — if the diff is huge, say what could be split out. No "fixes stuff".
