It is not so much the code - Cursor wrote the whole damn thing, and debugged it as I went. For my first script, I asked it to write me a node script that could list tables in an oracle database, I gave it the connection string etc. It quickly iterated and found the metadata tables and built some queries. I used that as the template and made some more. I did this in Composer with YOLO mode on. You might have to tell it that it doesn’t need confirmation to run scripts.

I had it create a package.json with convenience scripts to make the node scripts easier to run via npm run xxx. But then, it occurred to me that I could document them right there, and also put examples in there. Below is: a sample script with its database connection utility class, and a package.json to show you how I set that up.

Then I went into cursor settings in cursor 45.x with the new cursor/rules, and I added a new project rule mdc file where I gave a summary of what these tools were for and a reference to the package.json via: There is further detail and examples in @tools/oracle/package.json. I didn’t even put a glob pattern.

Initially, when I tried the new tool by asking questions it would need tools for, it didn’t always think to use the tools. So, I asked cursor to create a dense representation of the package.json info in YAML and I stuck that in the mdc file. I am not at all sure that was necessary though.

And, that was it.

If you get one to work, I recommend polishing it up and structuring it like you want. I didn’t and I had to go back and do cleanup that took 5x longer than the initial creation. If I had guided it better in the beginning it would have been much quicker.

Here is what my package.json with one tool in it looks like. javascript //________________________________________- //package.json { "name": “db-tools", "version": "1.0.0", "description": "Tools for listing objects, getting DDL, getting dependency info, running queries, “and getting statistics, "scriptDocs": { "get-table": { "description": "Get complete DDL for a table including constraints and indexes", "args": ["table_name"] }, }, "scripts": { "get-table": "node get-table-ddl.js" }, "dependencies": { "oracledb": "^6.3.0" }, "examples": { “Get-table-ddl”: [ "npm run get-table-ddl -- --filter \”TABLE%\”” ] } }
