canon-rtl

canon-rtl is a skill for Claude Code, Codex from Dragoon0x/canon. It costs 75 tokens per session (1,057 once invoked), scanned A, original, MIT.

A guide for supporting right-to-left languages such as Arabic, Hebrew, Farsi, and Urdu. It explains how text and interface flow should mirror while some icons and media controls should not.

In plain words
What is it for?
Use it to add RTL support, mirror navigation and directional icons correctly, handle bidirectional text, and replace left/right CSS with logical properties.
Why use it?
It helps avoid interfaces that look reversed incorrectly or break when the reading direction changes. It recommends HTML and CSS patterns that work in both directions.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

canon-rtl scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

CANON · RTL

RTL is not "flip everything." It's about reading direction. Text, layout flow, and directional icons mirror. Decorative elements, media controls, and universal icons do not.

Set the direction

<html lang="ar" dir="rtl">

dir="rtl" on <html> flips the entire document flow. Browser handles most text and flexbox/grid automatically.

Use CSS logical properties

Physical properties break in RTL. Logical properties work in both directions automatically.

Physical (avoid) Logical (use)
margin-left margin-inline-start
margin-right margin-inline-end
padding-left padding-inline-start
text-align: left text-align: start
float: left float: inline-start
left: 0 inset-inline-start: 0
border-left border-inline-start
.sidebar { margin-inline-start: 24px; padding-inline-end: 16px; }

What mirrors (flips in RTL)

  • Text alignment and flow
  • Flex and grid direction (row → row-reverse)
  • Navigation order (left-to-right becomes right-to-left)
  • Breadcrumbs (Home > Products becomes Products < Home)
  • Directional icons: back arrow, forward arrow, chevrons pointing "forward/backward"
  • Progress bars, sliders, timeline direction
  • Lists with indentation
  • Form layout: labels relative to inputs

What does NOT mirror

  • Media playback controls (play/pause/seek are universal)
  • Phone number fields (always LTR, digits are universal)
  • Clocks (clockwise is universal)
  • Logos and brand marks
  • Checkmarks, plus/minus, close X
  • Up/down arrows (vertical is directionless)
  • Images and photos (don't flip)
  • Charts with mathematical axes (0 at origin)
  • Slash direction in paths (/Users/path)

Bidirectional text (bidi)

Mixed LTR and RTL content in the same string (e.g., Arabic text with an English brand name):

<p>مرحباً بك في <bdi>CANON</bdi> للتصميم</p>
  • <bdi> isolates the embedded text direction.
  • Never rely on Unicode control characters manually. Use HTML elements.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
