Apply when you write the same instruction a second time, or notice a recurring correction, such as a join that drops rows, a timezone mix-up, or a chart axis that starts in the wrong place. Encode the rule as a data test, lint rule, schema check, or script instead of more text.

The file

We split this skill into the rules it gives an agent

3 rules. 1 is common, 1 is distinctive, and 1 is very specific to this project.

  • 1

    Common

    Most of the 48 edited versions we read keep these.

  • 1

    Distinctive

    This author's own choices. Worth a look.

  • 1

    Very specific

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

  • Common
  • Distinctive
  • Very specific
  1. Very specific:

    If the lesson can be encoded, encode it.

    line 8
  2. Distinctive:

    If the lesson needs judgment and cannot be encoded, make the instruction more prominent and add an example of the failure mode.

    line 10
  3. Common:

    If the fix is structural, use only the structural fix.

    line 12

“Common” is measured: kept by at least 6 in 10 of the 48 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.

Encode Lessons in Structure

If the lesson can be encoded, encode it. A data-quality assertion, a ruff rule, a dtype check in the loader, or a pre-commit hook enforces the rule every time. A note in the README that says "order_date is UTC" does not.

If the lesson needs judgment and cannot be encoded, make the instruction more prominent and add an example of the failure mode.

If the fix is structural, use only the structural fix. The instruction is the symptom.
