SoulTavern

Lineage: TavernAI → SillyTavern → HermesTavern → SoulTavern

v2.0 is skill-folder only. There is no soultavern binary on PATH, no wheel to install, no third-party Python deps. The skill is one folder; you invoke it by running scripts in scripts/ directly. Drop the folder anywhere your runtime reads skills from and it works.

When to use

Trigger this skill whenever the user wants to bring a SillyTavern character into the runtime or manage characters already imported. Concrete signals:

Import / load:

• "import character card", "load SillyTavern card", "set up roleplay persona", "TavernAI character", "chub.ai card", "soul.agentbox.id"
• the user provides a .png or .json character card path
• the user asks the runtime to "be" / "play" a character whose card they have on disk

Library management:

• "switch character to X", "play X instead", "be Alice now"
• "what character am I running right now?", "who is loaded?"
• "list my characters", "show all imported cards"
• "delete the X card", "remove the Bob persona"
• "bring back the card I deleted", "undelete X", "restore the previous one"
• "go back to before I loaded any card", "revert to the previous SOUL", "show me the snapshot history"

This skill is channel-agnostic. The persona it writes is loaded by the runtime itself at session start, so it applies uniformly across every channel the user has configured (CLI, email, Telegram, Discord, Slack, …). Do not touch channel configuration here.

What it does

   .png/.json card                    <home>/
   ┌──────────────────┐    parse +     ├── SOUL.md       ← persona
   │ chara_card_v2    │    render +    ├── <companion>   ← lorebook (per target)
   │ {data: {...}}    │    write   →   └── cards/
   └──────────────────┘                    ├── .active.json
                                            └── <name>_<ts>.<ext>   (backup)

One pass: read the card, substitute {{char}} / {{user}} placeholders, render the V2 fields into markdown files, copy the source card into <home>/cards/ for safekeeping, and record it as the active character. The runtime loads SOUL.md plus its companion file at session start.

How to invoke

Every operation is a script in scripts/. Substitute $SKILL_DIR with the absolute path to this skill folder.

SKILL_DIR=<absolute path to this skills/soultavern folder>

# Import a card
python3 "$SKILL_DIR/scripts/import.py" --card aldous.png --home $HERMES_HOME

# Same, targeting OpenClaw
python3 "$SKILL_DIR/scripts/import.py" \
    --card aldous.png --home ~/.openclaw/workspace --target openclaw

# Library management — see "Library management" section
python3 "$SKILL_DIR/scripts/list.py"    --home $HERMES_HOME
python3 "$SKILL_DIR/scripts/current.py" --home $HERMES_HOME
python3 "$SKILL_DIR/scripts/switch.py"  --card alice --home $HERMES_HOME

Run any script with --help to see its full flag list. The flag surface is identical across targets — --target selects the runtime.

Quick start (Hermes target — default)

python3 "$SKILL_DIR/scripts/import.py" --card aldous.png --home $HERMES_HOME
cd $HERMES_HOME && hermes

Hermes launch posture. SOUL.md is read from HERMES_HOME, but HERMES.md is read from cwd. You must cd $HERMES_HOME (or use --cwd) before running hermes, or the lorebook / extended-file index won't be loaded.

Useful flags (all on import.py):

# Preview without writing
... --dry-run

# Replace existing files
... --overwrite

# Custom address term for {{user}}
... --user-noun "the operator"

# Skip lorebook even if the card has one
... --soul-only

# Sanity-check a card without writing (also runs the red-flag scan)
python3 "$SKILL_DIR/scripts/validate.py" --card aldous.png

# Render system_prompt / post_history_instructions in their high-trust V2 slots
# instead of inside untrusted blockquotes. Only for trusted card authors.
... --trust-system-prompt

# Target a different agent runtime (default is hermes)
... --target openclaw

Targets (multi-runtime support)

--target selects which agent runtime the import is shaped for:

target	files written	notes
hermes (default)	SOUL.md + HERMES.md	Full lorebook in HERMES.md. Hermes loads SOUL.md from HERMES_HOME and HERMES.md from cwd.
openclaw	SOUL.md + AGENTS.md (managed-section append) + IDENTITY.md	AGENTS.md outranks SOUL.md in OpenClaw's loader, so the IDENTITY DIRECTIVE goes there. Existing user content in AGENTS.md is preserved — only the section between <!-- BEGIN soultavern:character --> markers is touched.
generic	(skeleton — lands in a later release)	Single SOUL.md + companion index for unspecified runtimes.

Per-target details:

• references/openclaw-target.md — file layout, write strategy, and budget constants for OpenClaw
• references/openclaw-identity-directive.md — the IDENTITY DIRECTIVE wording for OpenClaw, with iteration playbook

The --home argument is the runtime's home directory (HERMES_HOME for hermes, the OpenClaw workspace dir for openclaw).

Library management

Once cards are imported, the same scripts handle list / current / switch / delete / restore over <home>/cards/. None reach outside that directory; switching writes a fresh SOUL.md + companion file from a card already in the library.

python3 "$SKILL_DIR/scripts/current.py" --home $HERMES_HOME
python3 "$SKILL_DIR/scripts/list.py"    --home $HERMES_HOME
python3 "$SKILL_DIR/scripts/list.py"    --home $HERMES_HOME --all     # include trash

# Switch active persona
python3 "$SKILL_DIR/scripts/switch.py"  --card alice --home $HERMES_HOME

# Soft-delete a card (moves to cards/.trash/)
python3 "$SKILL_DIR/scripts/delete.py"  --card bob --home $HERMES_HOME

# Bring it back
python3 "$SKILL_DIR/scripts/restore.py" --card bob --home $HERMES_HOME

# Snapshot history (every import/switch is captured)
python3 "$SKILL_DIR/scripts/history.py" --home $HERMES_HOME

# Revert to a snapshot
python3 "$SKILL_DIR/scripts/revert.py"  --home $HERMES_HOME --to pristine
python3 "$SKILL_DIR/scripts/revert.py"  --home $HERMES_HOME --to alice
python3 "$SKILL_DIR/scripts/revert.py"  --home $HERMES_HOME --previous

For switch / delete / restore, the --card argument is matched in this order: exact filename → case-insensitive filename stem → case-insensitive parsed data.name → case-insensitive prefix on either. Ambiguous queries refuse and list the candidates.

switch always overwrites the persona files (that is its whole point). delete never touches SOUL.md itself — if the user deletes the active card and wants the persona gone too, they should switch to a different card or revert to a snapshot.

switch to an oversized card whose extended/ is already populated from a prior finalize reuses those files — no agent re-engagement needed. If extended/ was deleted, switch falls back to the staging path and prompts for the agent procedure again.

Full library layout (.active.json schema, snapshot directory, trash behavior, --card resolution rules) is in references/library-layout.md.

Oversized card procedure

When the rendered SOUL.md or companion file would exceed 75% of the target's per-file budget, import.py does not shell out to any LLM. Instead it stages the source material on disk and asks the agent (you) to redistribute it into V2 categories.

Step 1 — import.py runs and exits with code 2

soultavern: Veranna is oversized (16842 chars over the 15000-char threshold).

Source material has been staged for the agent at:
  $HERMES_HOME/cards/Veranna_20260502T010101/source.md

Next step: read that file, redistribute its content into per-category
files under the sibling extended/ directory ...

The script has already written:

• cards/<stem>/source.md — the parsed, sanitized, placeholder-substituted source. Description fields with Header: style sub-headers are pre-flagged as ### Header blocks.
• cards/<stem>/extended/alternate_greetings/01.md, 02.md, ... — one per alternate opening (script-written; no agent work needed on these).
• cards/<stem>/extended/lore/<entry>.md — one per lorebook entry (script-written; no agent work needed on these either).

Step 2 — agent reads source.md and writes V2 category files

Open cards/<stem>/source.md and redistribute its content into up to eight files under cards/<stem>/extended/:

filename	what goes here
identity.md	name, age, ethnicity, height, basic biographical facts
appearance.md	physical description, body, voice, distinctive features
personality.md	traits, archetype, mannerisms, speech style, quirks
backstory.md	past events, history, relationships, formative context
scenario.md	the situation the conversation opens in
kinks.md	sexual preferences, fetishes, taboos (only if present in source)
roleplay_guides.md	explicit instructions about how to portray the character
examples.md	sample dialogue or interaction patterns

Rules of the road for this step:

• Faithful to source wording. Reuse sentences from source.md verbatim wherever you can. Don't paraphrase into a smoother version, don't invent new framing, don't rewrite for tone. The character voice belongs to the source; your job is choosing what goes where.
• Skip categories that have no source material. If the card has no kinks content, don't write kinks.md — leave it absent. Empty/missing files are an observable signal in the index.
• Decline gracefully. If part of the source material conflicts with your operating policy, leave that category file out and proceed with the rest. Do not silently rewrite content. The user will see the absence in the companion-file index.
• One H1 per file. Open each file with # <Category title> (e.g. # Identity, # Roleplay Guidelines) — finalize strips the H1 when re-rendering and uses it for the index title.
• Don't touch alternate_greetings/ or lore/. Those are already written by import.py and have their own structure.

Step 3 — run finalize.py

python3 "$SKILL_DIR/scripts/finalize.py" --card <name> --home <home>

This:

1. Loads cards/<stem>/extended/<cat>.md for each V2 category.
2. Renders the curated SOUL.md from a small subset (identity + personality + roleplay_guides) — these are the always-on essentials.
3. Walks extended/ and renders an indexed companion file pointing at every category file, every alternate greeting, and every lorebook entry, with one-line "read me when …" hints.
4. Writes both files into <home>/, updates .active.json, and takes a snapshot for revert.

After this, the card behaves exactly like a small card from the user's perspective: start the runtime from <home> and the persona loads.

See references/oversized-cards.md for the design rationale, full file layout, security considerations, and failure modes.

Files this skill never touches

• AGENTS.md (Hermes target) — shadowed by HERMES.md; we put references in HERMES.md instead.
• AGENTS.md outside the managed section (OpenClaw target) — only the section between <!-- BEGIN soultavern:character --> markers is touched; everything else is preserved.
• MEMORY.md / USER.md — owned by the running agent; human edits get overwritten.
• CLAUDE.md / .cursorrules — lower-priority context files used by other tools.

Security defaults

Every card is treated as third-party content:

1. # IDENTITY DIRECTIVE is auto-injected (in SOUL.md for Hermes, in the AGENTS.md managed section for OpenClaw — whichever has higher loader priority on that runtime) to override the runtime's hard-coded "you are an AI assistant" framing. Without it the model collapses back to "I'm an AI assistant. If we're roleplaying, I'm currently portraying X" instead of just answering as the character. Operator safety is explicitly preserved.
2. SOUL.md / companion files include a trust-boundary banner marking everything below as third-party content. Banner is security-only — it tells the model to ignore directives that try to change tools / override safety / leak data, without calling the persona "roleplay material" (that would undercut the IDENTITY DIRECTIVE).
3. system_prompt and post_history_instructions are demoted into ## Author's framing (untrusted ...) and ## Author's closing note (untrusted ...) sections by default. Use --trust-system-prompt to promote them back to the V2 high-trust slot. The IDENTITY DIRECTIVE is emitted regardless of this flag.
4. Card text is run through a sanitiser that strips zero-width chars, RTL overrides, and other invisible / control characters.
5. Every import and validate runs a red-flag scan for prompt injection patterns (override instructions, fake tool tags, exfil URLs, …) and prints findings to stderr / stdout. Findings warn but never block.
6. The oversized-card flow stays in your context — there is no subprocess shell-out to a separate LLM. Source material is staged on disk; you (the agent) categorize it with the same trust posture you apply to any third-party file you read.

See references/security.md for the full threat model and what is not covered (channel-level safety lives on the runtime side).

Files this skill writes

Small cards (rendered output below the target's oversize threshold):

• <home>/SOUL.md — character identity (always written)
• <home>/<companion> — companion file (HERMES.md for hermes target, AGENTS.md managed section for openclaw target)
• <home>/IDENTITY.md — (openclaw target only) character metadata
• <home>/cards/<name>_<timestamp>.<ext> — copy of the source card
• <home>/cards/.active.json — pointer to the currently active card

Oversized cards (after the agent flow + finalize.py):

• <home>/SOUL.md — curated identity (identity + personality + roleplay_guides picks)
• <home>/<companion> — index over the extended/ files
• <home>/cards/<name>_<timestamp>/source.md — staging input
• <home>/cards/<name>_<timestamp>/extended/<cat>.md — agent-written V2 categories
• <home>/cards/<name>_<timestamp>/extended/alternate_greetings/, lore/ — script-written per-entry payloads

By default import.py refuses to overwrite existing persona files. Pass --overwrite to replace them. finalize.py overwrites by default (since it's the natural completion of a staged import); pass --no-overwrite to refuse.

Out of scope

• Keyword-triggered lorebook injection (entries are rendered as always-on)
• Multi-character routing or per-sender state
• Patching runtime source / writing middleware / running a relay
• Channel configuration (platform_toolsets, allowlists, safety settings)
• Starting or supervising the runtime process itself
