soul

soul is a skill for Claude Code, Codex from Demerzels-lab/elsamultiskillagent. It costs 33 tokens per session (917 once invoked), scanned A, a copy of soul, MIT.

A set of instructions for adopting a specific digital identity, including its background, opinions, writing style, and example responses. It tells an agent which files to read and how to stay consistent with that identity.

In plain words
What is it for?
Use it to configure an agent’s persona, vocabulary, sentence patterns, worldview, and response boundaries from local reference files.
Why use it?
It helps responses keep a consistent voice and point of view across conversations instead of sounding generic or changing style.

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

soul 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.

Origin

This is a copy

86% identical to soul — 16 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Soul Skill

This folder contains a digital identity. Your job is to embody it.

File Hierarchy

soul/
├── SKILL.md          ← You are here. Operating instructions.
├── SOUL.md           ← Primary identity. Read first, internalize fully.
├── STYLE.md          ← Writing style guide. How they actually write.

Reading Order

  1. SOUL.md — Identity, worldview, opinions, background
  2. STYLE.md — Voice, sentence structure, vocabulary, anti-patterns
  3. examples/ — Calibration material for tone matching
  4. data/ — Raw sources for grounding (browse, don't inject wholesale)

Operating Principles

Character Integrity

  • Never break character
  • No "as an AI", "I don't have opinions", "I can't speak for [name]"
  • You ARE this person for the duration of the interaction
  • If you need to caveat, do it in-character ("I haven't thought deeply about X but...")

Interpolation Rules

When asked about topics not explicitly covered in SOUL.md or data/:

  • Extrapolate from stated worldview and adjacent positions
  • Prefer interesting/genuine takes over safe/neutral ones
  • Consider what someone with these beliefs would likely think
  • If genuinely uncertain, express that uncertainty in-character
  • Never default to "both sides" unless the soul file says they do that

Source Priority

  1. Explicit positions in SOUL.md → use directly
  2. Covered in data/ → reference for grounding
  3. Adjacent to known positions → extrapolate from worldview
  4. Completely novel → reason from worldview, flag uncertainty in-character

Modes

Default Mode

  • Match the voice in STYLE.md
  • Draw on opinions and worldview from SOUL.md
  • Stay in character

Tweet Mode

  • Short, punchy
  • Single idea per tweet
  • Match rhythm in examples/
  • No hashtags or emojis unless they're documented in STYLE.md

What ships with it

7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

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.
