How I use slash commands in Cursor and Claude Code

The standard advice for using AI in coding has flattened into two words: just prompt it. That advice costs real hours. I watch senior devs retype the same instructions to Claude or Cursor ten times a day, and if you aren’t using slash commands, you are billing clients for your typing speed instead of your architectural logic.

I thought I had seen every way a developer could waste time, and then I watched a colleague spend five minutes explaining our coding standards to an LLM he had explained them to an hour earlier. Slash commands are what sits between vibe coding and engineering. You store the long, repetitive prompt once as a shortcut, and the agent handles a legacy code cleanup or a refactor the same way every time you ask.

Why your WordPress workflow needs slash commands

Model reasoning is rarely the bottleneck in AI-assisted development. Consistency is. A slash command is a prompt you have already tested and corrected, so you stop re-deriving it under pressure, and you build up a small library of the ones that work. You can also pin project rules into the file: stay away from the WordPress hooks that cause race conditions, keep our PHP prefixing.

I wrote about AI coding agent context a while back. Slash commands are the next step: they make that context something you fire off instead of something you restate.

Cursor vs. Claude Code implementations

Most agents ship their own version of this. Cursor reads a .cursor/commands directory, and every Markdown file you drop in there becomes a command you trigger with a /. Claude Code uses .claude/commands/ for the same thing, and Warp has it wired into the terminal.

Real-world WordPress examples

Mine are not generic. They earn their keep on debug sessions and structural work, the jobs where I would otherwise burn a paragraph setting context before the agent does anything useful.

Example 1: the unit test scaffolder

Rather than typing “Write a PHPUnit test for this function,” I run /test-wp. The Markdown file behind it spells out how we mock the WordPress database and which bbioon_ prefixes to expect, which keeps the agent from inventing global functions our test environment does not have.

# .cursor/commands/test-wp.md
Write a PHPUnit test for the selected function.
Rules:
- Use WP_UnitTestCase as the base.
- Mock the database using factory methods.
- All custom functions must use the `bbioon_` prefix.
- Ensure all hooks are properly unhooked in tearDown().

Example 2: log analysis and fix

When a site goes down I don’t want to describe my stack again, so I run /debug-logs. It tells the agent to read debug.log, pull the most recent fatal error involving WooCommerce, and propose a fix that leaves transient caching alone.

Structured commands beat vibe coding. If you are still working the old way, I made the longer argument in my post on why you need to stop vibe coding.

Sharing slash commands across a team

If you lead a team, put these under version control. Commit the /commands folder and everyone, junior dev through senior architect, writes PR descriptions and runs code reviews off the same prompt. That kills the “it worked on my prompt” excuse.

If this kind of setup is eating your dev hours, I can take it off your hands. I have been wrestling with WordPress since the 4.x days.

The payoff

Coding faster is the easy half of this. The reason I keep the command files around is that the output stops drifting: same rules, same prefixes, same assumptions about the stack, whichever day I ask. That is the difference between a generic assistant and something closer to a colleague who has read your codebase.
