What it does

Sillytavern Embedded UI is an agent skill from LiarMTTT/TavernWeave. Design, implement, or review framework-neutral embedded interfaces for SillyTavern rolecards, including opening pages, status bars, control centers, drawers, and popups. Use for HTML/CSS/JavaScript structure, interaction states, responsive behavior, accessibility, safe rendering, specifications for optional project-specific frontend sandboxes using real source, and the real-runtime handoff. Do not use as the primary skill to close behavior in a live SillyTavern instance; hand that work to sillytavern-runtime-debug.

Its SKILL.md is about 4.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `agents/openai.yaml`, `references/adapter-contract.md` and `references/sandbox-recipes.md`).

It sits in Frontend & Design. It works with JavaScript. The repository describes itself as: Noncommercial Agent Skills for SillyTavern rolecard engineering.

When your agent uses it

  • HTML/CSS/JavaScript structure
  • Interaction states
  • Responsive behavior
  • Specifications for optional project-specific frontend sandboxes using real source

Example prompts

  • “/sillytavern-embedded-ui”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. wait for a successful rebuild and stop on compiler errors;
  2. hand the new output identity to sillytavern-runtime-debug;
  3. verify that Tavern Helper reloaded the intended message or script iframe, or use the
  4. inspect the resulting DOM, console, interaction, and data state before continuing.

What it can do on your machine

Read from SKILL.md and the folder at commit d9da0b0. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Sillytavern Embedded UI loads about 4.6k tokens when it runs, and up to ~8.5k if it reads all its reference files. Until then it costs about 136 tokens; SKILL.md has 2,420 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~136
When it runs · the whole SKILL.md, loaded when a task matches
~4.6k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~8.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 2,420 words (~4,646 tokens).

“Apply TW plain-language and guidance rules to user-facing work. Explain terms in context; preserve the user's chosen 新人/入门/熟练/老手 level without inferred changes. 新人 and 入门 receive detailed explanations; every level receives needed and bug explanations unless the user explicitly waives…”
