How to use Craft / Rules & guards

Rules & guards.

Prompts are wishes; rules are enforcement. Say a rule once and it holds on every future draft, in every tool, no matter which model is writing.


  1. 1State it

    Say the rule once.

    Every rule gets a tier: style yields to intentional craft (a banned word inside a quote doesn't fail), policy never yields. Rules can be scoped — only headlines, never inside quotes, only long-form.

    Add a rule to my Newsletter profile: never use em-dashes.

    A policy rule

    Hard compliance rule: we never promise returns. That one can never be excepted.

    The em-dash ban matches the — glyph itself, not the word “em-dash” — the most-requested rule, done right.

  2. 2Arm the guards

    Five defenses, one ask each.

    • Anti-slop pack — the curated AI-ism lexicon (“delve”, “seamless”…), flagged and auto-removable.
    • Voice band — drafts that drift off your rhythm get flagged, per channel.
    • Opener signature — your opening/closing pattern, enforced.
    • Diction band — synonyms you never use, swapped for your word.
    • Quote & attribution integrity — quotes must exist in your sources; figures need attribution. Policy tier.

  3. 3House terms

    Terminology that corrects itself.

    Glossary entries bind deprecated variants to the sanctioned term — fixed by replacement, never deletion, applied automatically with a redline.

    Glossary: we say 'sign in', never 'log on' or 'login' as a verb.

  4. 4Stay fair

    Dismiss false positives — keep the rule.

    When a good ban flags a legitimate use, don't delete the rule — teach the exception. The same usage never nags again; a different usage still fails. Approving a passage teaches its exceptions automatically.

    That 'delve' is inside the professor's quote — allow this usage.

    Policy rules can't be excepted — by design.

  5. 5Positions

    Teach it what you believe.

    Voice is also stance. Declare positions and lenses; relevant ones reach the brief, and checks add an advisory note when a draft touches one — a reminder, never a violation.

    Position for my Column profile: I read every platform story through the incentive-structure lens.
