  1. Copy

    Global CLAUDE.md / AGENTS.md rules
    Writing rules, from Orwell, 1946. These govern prose: docs, PR text, messages. Never touch code or technical terms; swap in everyday words only where precision survives.
    1. Never use a metaphor, simile or other figure of speech which you are used to seeing in print.
    2. Never use a long word where a short one will do.
    3. If it is possible to cut a word out, always cut it out.
    4. Never use the passive where you can use the active.
    5. Never use a foreign phrase, a scientific word or a jargon word if you can think of an everyday English equivalent.
    6. Break any of these rules sooner than say anything outright barbarous.
    Review every prose output against these rules before delivering.
  2. Paste the rules into your global CLAUDE.md or AGENTS.md.

  3. You get

    Docs, PR text and reports in plain words in every session, without banning words one at a time.

Scope Guard: AGENTS.md rules for small tasks

Asked to change a config, it builds a framework: minimum sufficient change, reuse first, ask before widening, test narrowly.

Codebase + Review

Taglines, helper text and labels on every screen: one line cuts them so the layout speaks for itself; one weighs UX, DX and AX.
