My Rules

An MCP server for all my rules, prompts, etc etc. Allows agents to call rules on demand.

There's no point filling 4 paragraphs of instructions for how to write tests if your current session isn't going to write a test.

Spiritually similar to Cursor's rules.

What's It Do?

Allows coding agents to lookup rules on demand within the context of their current task.

Why?

• It's really annoying trying to carry all these little notes between projects/IDEs.

• I don't want to have to manually invoke rules.

How's It Work?

Clearly-defined tool descriptions allow the agent to fetch rules on demand, only if they appear to be relevant.

What Doesn't work?

• Patterns must be associated with a specific action. For example, "writing tests", "authoring UI", "reviewing a PR".

• The agent ultimately decides if it's going to call the tool. Sometimes it does. Sometimes it doesn't.

Tools

1. get_rules_for_writing_tests

   • Use when: writing any type of test,

   • Inputs:

     • language (string)

2. get_rules_for_composing_ui

Prompts

In Claude Code, invoke prompts as slash commands.

1. pr-review

• Use when: you want feedback on a unit of work

• /pr-review

• See resources/pr-review.md for the full template.
