**Hallmark applies six mandatory disciplines across every verb (`default`, `audit`, `redesign`, `study`, etc.) to eliminate AI-generated artifacts and enforce production-ready output standards.** These disciplines are defined in [`skills/hallmark/SKILL.md`](https://github.com/Nutlope/hallmark/blob/main/skills/hallmark/SKILL.md) and evaluated by an internal **slop-test** before any content is emitted.

Whether you're running the `default` verb to generate landing pages or the `audit` verb to review existing code, Hallmark enforces the same quality baseline. The codebase in [Nutlope/hallmark](https://github.com/Nutlope/hallmark) implements these as non-negotiable guardrails rather than optional guidelines.

## Pre-Emit Self-Critique: The Six-Axis Quality Gate

Before returning any artifact, Hallmark scores it on six evaluation axes: **Philosophy**, **Hierarchy**, **Execution**, **Specificity**, **Restraint**, and **Variety**. If any score falls below 3, the system forces a revision.

This discipline guarantees strategic and stylistic rigor regardless of output type. The scoring logic can be implemented as follows:

```javascript
function preEmitCritique(artifact) {
  const scores = {
    philosophy: 5,
    hierarchy: 4,
    execution: 5,
    specificity: 4,
    restraint: 5,
    variety: 5,
  };
  const minScore = Math.min(...Object.values(scores));
  if (minScore < 3) {
    return { status: 'REJECT', revise: true, lowestAxis: getLowestAxis(scores) };
  }
  return { status: 'PASS', artifact };
}

```

The six-axis framework prevents shallow or mechanically-generated output from reaching production, as documented at [SKILL.md L46](https://github.com/Nutlope/hallmark/blob/main/skills/hallmark/SKILL.md#L46).

## Honest Copy: Zero Fabrication Policy

**Hallmark never invents metrics, testimonials, or logos.** All quantitative claims must use real numbers, explicit placeholders, or be omitted entirely.

This discipline directly targets a notorious AI failure mode: the confident generation of plausible-sounding but entirely fabricated statistics. The enforcement is strict—no exceptions for "realistic-looking" fake data, as specified at [SKILL.md L48](https://github.com/Nutlope/hallmark/blob/main/skills/hallmark/SKILL.md#L48).

## Locked Tokens: Design System Determinism

Every **color** and **font-family** must reference a named design token. Inline values like `color: #3b82f6` or `font-family: 'Inter'` are prohibited.

This creates a single source of truth and makes the design system portable across projects. Token enforcement ensures that:

- Theme changes propagate through token redefinition
- No orphaned values exist in generated output
- Design systems remain maintainable at scale

The locked tokens rule is defined at [SKILL.md L50](https://github.com/Nutlope/hallmark/blob/main/skills/hallmark/SKILL.md#L50).

## Re-Drawn Chrome Forbidden: Authentic UI Only

Hallmark **must not fabricate browser chrome, phone frames, IDE interfaces, or device bezels.** Only real screenshots or clean content without decorative framing are permitted.

This eliminates the "fake UI chrome" anti-pattern that signals low-effort mock-ups rather than real product work. The restriction applies to all visual output regardless of verb, as documented at [SKILL.md L52](https://github.com/Nutlope/hallmark/blob/main/skills/hallmark/SKILL.md#L52).

## Mobile Responsiveness: Four-Breakpoint Verification

Every emitted page must render without horizontal scroll at **320px, 375px, 414px, and 768px** breakpoints. Spacing, typography, and layout must remain correct across all four widths.

This sets a non-negotiable floor for production code. The mobile-first requirement is not aspirational—it is mechanically enforced before output approval, per [SKILL.md L54](https://github.com/Nutlope/hallmark/blob/main/skills/hallmark/SKILL.md#L54).

## Typography Purity: No Italic Headers

**Headings and display type remain roman (upright).** Emphasis is conveyed through weight, color, or underline—never through italics.

This removes a classic AI tell (italicized headings) and maintains clean typographic language. The prohibition applies to all heading levels and display text, as specified at [SKILL.md L56](https://github.com/Nutlope/hallmark/blob/main/skills/hallmark/SKILL.md#L56).

## Summary

- **Pre-emit self-critique** enforces six-axis quality scoring with mandatory revision on failure
- **Honest copy** eliminates fabricated metrics and testimonials entirely
- **Locked tokens** require all visual values to reference named design system tokens
- **Re-drawn chrome forbidden** bans fabricated browser/device frames
- **Mobile responsiveness** mandates verification at 320/375/414/768px breakpoints
- **Typography purity** prohibits italic headings in favor of weight and color emphasis

These six universal disciplines are defined in [`skills/hallmark/SKILL.md`](https://github.com/Nutlope/hallmark/blob/main/skills/hallmark/SKILL.md) under the heading *"Disciplines that hold across every verb"* and evaluated by Hallmark's internal slop-test before any output is emitted.

## Frequently Asked Questions

### Where are the six universal disciplines defined in the Hallmark codebase?

The six disciplines are documented in [`skills/hallmark/SKILL.md`](https://github.com/Nutlope/hallmark/blob/main/skills/hallmark/SKILL.md) at lines 46-56, under the section *"Disciplines that hold across every verb."* This file serves as the canonical specification for all quality guardrails applied regardless of which verb is executed.

### How does Hallmark enforce these disciplines before output is returned?

An internal **slop-test** evaluates every artifact against the six disciplines before emission. The pre-emit self-critique specifically uses a six-axis scoring system (Philosophy, Hierarchy, Execution, Specificity, Restraint, Variety) with a minimum threshold of 3/5 on each axis, forcing automatic revision on any failure.

### Do these disciplines apply to all Hallmark verbs equally?

Yes. The documentation explicitly states these disciplines hold across **every verb**—including `default`, `audit`, `redesign`, and `study`. No verb receives exemptions from the six-discipline framework, ensuring consistent output quality regardless of use case.

### What happens if a design uses inline color values instead of tokens?

The artifact fails the **locked tokens** discipline. Hallmark requires every color and font-family to reference a named design token; inline values like hex codes are prohibited. This failure would trigger revision through the slop-test mechanism before any output is returned to the user.
