Apply when integrating a new requirement into an existing design. Redesign as if the requirement had been a foundational assumption from day one, instead of bolting it on.

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 38 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 9
  2. Common:

    Read all affected files and understand the current design holistically

    line 11
  3. Common:

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

    line 12

“Common” is measured: kept by at least 6 in 10 of the 38 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 there from the start. The result should look like what we would have built if we'd known on day one.

  • Read all affected files and understand the current design holistically
  • 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 redesign holistically, then deliver it incrementally

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

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.
