Wrote up five specific ways Rails' "boring" conventions turn out to be an unfair advantage when the reader is an LLM.

Rails didn't set out to be AI-friendly. It is optimized for the tenth engineer joining on day one.

LLMs want the exact same thing, for the exact same reason.

Full write-up, five conventions:

Spent the last few months watching a Claude-based agent read our production Rails codebase — tracing scopes, following jobs, finding bugs I'd written years ago.

The strange thing isn't that it works.

It's how little I had to do to make it work.

🧵 1/7

[Raj Kumar @raj_abc38]

`config/routes.rb` is the densest map of app structure I've ever handed an LLM.

Ticket → routes → controller → service → line where the exception was raised. Under a minute, zero guidance, no custom index, no LSP.

One file, top to bottom.

> AuditTrailReplayJob.perform_later(study_id, since: 24.hours.ago)

You told me what happens without reading the class.

Alternative: generic queue + JSON payload + routing consumer. Four files, three inferences, one typo away from silent breakage.

5/7

[Raj Kumar @raj_abc38]

Active Record scopes are self-documenting in a way that no repository pattern is.

Tenancy rule + association path + lifecycle rule. One line. Agent reads once, knows.

4/7

[Raj Kumar @raj_abc38]

`app/services/` is a keyword — even to the model.

Ask where the logic for X lives; it opens app/services/ and is often right on first read. Trained on millions of Rails apps following the convention.

Per-repo clever conventions don't compound. Shared ones do.

3/7

[Raj Kumar @raj_abc38]

Mental model that helped most: the agent is a new hire on day one.

No institutional memory. General knowledge of Ruby/Rails. Reads fast, forgets nothing, believes what it reads.

Under that frame, every naming/layout decision is either cheap or expensive for the agent.

@UppclChairman @PuVVNLHQ @UPPCLLKO @myogioffice @CMOfficeUP @BJP4UP @BJP4India @myogiadityanath @myogioffice - Is it any surprise that voters are dissatisfied when governance is so abysmal that even the smallest public grievances have been ignored for years under the Babushahi?

@UppclChairman @UPPCLLKO @PuVVNLHQ

[Raj Kumar @raj_abc38]

@PuVVNLHQ kept closing my online requests from last 2-3 yrs without taking action for name correction. It's a data entry issue by deptt itself. There is no way other than to raise a new request. My latest request number is 3630148913. Kindly fix the data and stop harassing custs

[Raj Kumar @raj_abc38]

@UppclChairman @PuVVNLHQ @UPPCLLKO Surprised by the lack of attention to customer concerns from top officials like @UppclChairman, @UPPCLLKO, and @PuVVNLHQ. No response, not even an automated one. Hoping for a solution soon; reaching out to @myogioffice as a last resort. #uppcl #YogiAdityanath

@TheOfficialSBI @RBI @SBIChairman Anybody??? @CGMSBICha, @TheOfficialSBI, @RBI , @SBIChairman

[Raj Kumar @raj_abc38]

@TheOfficialSBI 2 weeks ago, I created an FD from a savings account using internet banking. I got emails and notifications that amt has been deducted from savings a/c and FD has been created immediately.

However, even after a week that FD didn't show under my internet banking.

[Raj Kumar @raj_abc38]

@TheOfficialSBI Branch communication lacks control. Despite a guided call and assurance from the Bank Manager for resolution in 2 days, there's been no update even after follow-ups. They not responding to emails as well.

Almost 2 months and SBI is not bothered for the issue.

Yet another awesome addition of Ruby 3.1. Yes, the hash shorthand.
