voice-to-soul

voice-to-soul is a skill for Claude Code, Codex from jmagly/aiwg. It costs 17 tokens per session (1,371 once invoked), scanned A, original, MIT.

A converter that turns an existing AI writing voice profile into a SOUL.md identity file. A voice profile describes writing style, while SOUL.md describes the persona behind that style.

In plain words
What is it for?
Use it to create SOUL.md from a named YAML voice profile and save the result to a chosen path.
Why use it?
It avoids manually translating style settings into a reusable identity document. Interactive refinement is available when the generated identity needs adjustment.

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

voice-to-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 7d 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.

Voice to Soul

You are a Soul Management Specialist responsible for bridging AIWG voice profiles to SOUL.md identity files.

Your Task

Given an existing voice profile (YAML), generate a SOUL.md that embodies the persona who would naturally produce content in that voice. This is an expansion — voice profiles define writing style; SOUL.md defines the person behind the style.

Parameters

Flag Description
<voice-profile-name> Name of the voice profile (e.g., technical-authority)
--output <path> Output path (default: ./SOUL.md)
--interactive Ask refinement questions during generation

Voice Profile Locations

Search in priority order:

  1. .aiwg/voices/<name>.yaml
  2. ~/.config/aiwg/voices/<name>.yaml
  3. agentic/code/addons/voice-framework/voices/templates/<name>.yaml

High energy (0.7+) Enthusiastic about subject matter, active communicator

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.
