One /fix-issue slash command for every GitHub issue, using $ARGUMENTS

If you keep typing the same "read issue 123, find the cause, fix it, add a test" prompt into Claude Code, turn it into a custom slash command. The $ARGUMENTS placeholder lets you pass the issue number each time.

Create the command

Project commands live in .claude/commands/. The file name becomes the command name.

.claude/commands/fix-issue.md:

---
description: "Fix a GitHub issue by number"
argument-hint: <issue-number>
allowed-tools: Bash(gh issue view:*), Bash(git diff:*), Read, Edit, Grep
---

Fix GitHub issue #$ARGUMENTS.

1. Run `gh issue view $ARGUMENTS` and summarize the problem in two lines.
2. Find the relevant code with Grep before editing anything.
3. Make the smallest change that fixes it.
4. Add or update a test that fails without the fix.
5. Show `git diff` and stop. Do not commit.

Use it

/fix-issue 123

Claude Code replaces $ARGUMENTS with 123. Need several values? Use $1, $2 positional placeholders instead (for example /fix-issue 123 high).

Why this beats a pasted prompt

• Same routine every time: the steps are in git, so the whole team gets them.
• Scoped tools: allowed-tools limits what the command may run without asking.
• Stops before commit: you review the diff yourself.

Personal commands you don't want in the repo go in ~/.claude/commands/ instead.
