The file

We split this skill into the rules it gives an agent

3 rules. 3 are common, 0 are distinctive, and 0 are very specific to this project.

  • 3

    Common

    Most of the 46 edited versions we read keep these.

  • 0

    Distinctive

    This author's own choices. Worth a look.

  • 0

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Common:

    When integrating a change, don't bolt it onto the existing design.

    line 8
  2. Common:

    Read all affected files and understand the current design

    line 10
  3. Common:

    Ask: "if we were writing this from scratch with this new requirement, what would we build?"

    line 11

“Common” is measured: kept by at least 6 in 10 of the 46 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Redesign From First Principles

When integrating a change, don't bolt it onto the existing design. Redesign as if the requirement had been a foundational assumption from the start.

  • Read all affected files and understand the current design
  • Ask: "if we were writing this from scratch with this new requirement, what would we build?"
  • Propagate the change through every reference: types, docs, examples, rationale sections
  • Think about the whole redesign, then deliver it incrementally

This is the method for preserving option value when integrating changes into an existing design.

For module/interface reasoning invoke /codebase-design; for accepted project terminology, relationships, or ownership changes invoke /domain-modeling and reconcile the canonical project artifacts.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
