What it does
Tavern Card Builder is an agent skill from LiarMTTT/TavernWeave. Plan and author maintainable SillyTavern character cards, including card-type and capability detection, runtime-dependency ledgers, text cards, MVU or MVU Zod cards, custom CoT design and authoring, modular CoT stitching and routing, prompt budgets, retrofits, schemas, initialization, update rules, single-model or extra-model update routing, lorebooks, prompts, openings, regex requirements, and companion scripts. Use when creating or converting a card, adding a gameplay system, identifying which dependencies must…
Its SKILL.md is about 2.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 21 other files, including scripts and reference files (for example `agents/openai.yaml`, `references/authoring-workflow.md` and `references/card-types-and-runtime-dependencies.md`).
It sits in Development, covering Forms and validation. It works with Zod. The repository describes itself as: Noncommercial Agent Skills for SillyTavern rolecard engineering.
When your agent uses it
- Converting a card
- Adding a gameplay system
- Identifying which dependencies must be embedded
- Repairing an authoring protocol
Example prompts
- “/tavern-card-builder”
Requirements
- Node.js
Workflow steps
7 steps, taken from the first numbered list in SKILL.md.
- Read repository instructions and inspect the existing card before proposing a design.
- Identify the target SillyTavern, Tavern Helper, prompt-template, and MVU implementations or versions when behavior depends on them.
- Detect one primary card type plus capability flags from the actual card and
- Ask only decisions that materially change the result. Do not force a fixed interview ritual for a narrow edit.
- Independently decide whether the card needs a custom CoT, whether a reusable main
- For an MVU card, identify whether updates share the plot generation or use an
- Record unresolved version-sensitive claims as assumptions and keep a real-runtime acceptance gate.
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
Ships 1 file in scripts/ (JavaScript, from the files we listed), which the agent can run.
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
Tavern Card Builder loads about 2.8k tokens when it runs, and up to ~22k if it reads all its reference files. Until then it costs about 221 tokens; SKILL.md has 1,170 words of instructions outside code blocks.
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); the scripts in this folder 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 1,170 words (~2,762 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…”
