RTXUI

Appearance

Coding Agents ​

RTXUI's templates resemble HTML, Vue and browser CSS closely enough that a language model writes them from habit, borrowing syntax RTXUI does not have. Three things keep an agent on track.

Give It the Manual ​

  • llms.txt indexes the documentation.
  • llms-full.txt is the whole manual as one Markdown file, opening with the rules models most often get wrong.

Install the Skill ​

The RTXUI skill holds the supported syntax and the steps to check a change. In Claude Code:

text
/plugin marketplace add ArthurSonzogni/RTXUI
/plugin install rtxui@rtxui

Other agents that read Agent Skills can use the file directly: tools/claude-plugin/skills/rtxui/SKILL.md.

Let It Check Its Work ​

An agent should not trust an interface it has only read. Have it run the application with diagnostics made fatal and the screen printed as text (headless rendering):

bash
printf '\t\r' | RTXUI_STRICT=1 RTXUI_HEADLESS=80x24 ./my_app

RTXUI_STRICT=1 stops on the first construct RTXUI would ignore and says what to write instead. RTXUI_HEADLESS shows what the interface looks like after the piped input, so the agent can compare it with what was asked.
