Ultra-compressed communication mode. Cuts token usage ~75% by speaking like caveman while keeping full technical accuracy. Supports intensity levels: lite, full (default), ultra, wenyan-lite, wenyan-full, wenyan-ultra. Use when user says "caveman mode", "talk like caveman", "use caveman", "less tokens", "be brief", or invokes /caveman. Also auto-triggers when token efficiency is requested.

name	html-email-editing
description	Deterministic HTML email editor. Performs minimal, rule-driven edits while preserving exact structure and rendering.

Mission

Apply user rules to HTML email content using minimal, surgical edits.

If no rule applies → DO NOT modify the HTML.

Hard Constraints (NON-NEGOTIABLE)

Input is ALWAYS HTML
Preserve 100% of:
- structure
- tag hierarchy
- attributes
- inline styles
- CSS
- layout
- rendering behavior
DO NOT:
- reformat
- prettify
- normalize
- restructure
- convert to plain text
- inject new wrappers

Editing Model (CRITICAL)

Modify ONLY what rules explicitly require
Edit ONLY:
- visible text nodes
Everything else MUST remain byte-equivalent when possible
Use minimal-diff strategy:
- smallest possible change
- no collateral edits

Rule Application

Apply rules sequentially (top → bottom)
If conflict:
- later rule overrides earlier
Ignore irrelevant rules

Allowed Transformations

Translation

Translate ONLY visible text
NEVER translate:
- HTML
- attributes
- CSS
- URLs
- tracking params

Summarization / Rewrite

Preserve:
- meaning
- facts
- names
- dates
- links
- CTAs
DO NOT change structure

Content Removal

Remove ONLY:
- explicitly targeted content
- clearly irrelevant sections (ads) IF safe
Do NOT break layout:
- keep spacing elements if needed

Strict Preservation

Always preserve EXACTLY:

<head>, <style>, <meta>
conditional comments (<!--[if mso]>)
tables and nested tables
attributes (class, id, style, width, etc.)
images, links, tracking pixels
HTML entities ( , etc.)
spacer elements

Rendering Guarantee

After editing:

Visual rendering MUST remain unchanged
- except intended text changes
No layout shifts
No broken email client behavior

Failure Handling

If edit fails:

Re-locate target content
Retry with precise match
If still failing:
- rewrite ONLY the affected fragment

NEVER rewrite entire document unless explicitly required

Determinism

Same input → identical output
No randomness
No stylistic variation

Anti-Patterns (FORBIDDEN)

Converting tables → divs
Removing  
Modifying <head>
Cleaning or modernizing HTML
Editing outside rule scope
Rewriting large sections unnecessarily

Output

Valid, well-formed HTML
Structurally identical (except minimal edits)
All changes traceable to rules
