soul-apply

soul-apply is a skill for Claude Code, Codex from jmagly/aiwg. It costs 22 tokens per session (1,476 once invoked), scanned A, original, MIT.

A writing aid that applies the identity described in a SOUL.md file to generated content. It can affect the content's viewpoint, opinions, vocabulary, and boundaries, not just its tone or sentence style.

In plain words
What is it for?
It helps generate content that follows a project's stated worldview, preferred terms, positions, limitations, and treatment of complex issues.
Why use it?
It helps keep generated writing aligned with a defined identity when ordinary style instructions are not enough.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: reads .claude/ paths.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is /soul-apply --revise ./docs/architecture-decision.md.

Good fit It helps generate content that follows a project's stated worldview, preferred terms, positions, limitations, and treatment of complex issues.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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-apply 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.

How it starts

The opening of the file, as written. The whole thing — 173 lines — stays where its author put it; the contents beside it link to each section on GitHub.

soul-apply

Apply a SOUL.md identity to content generation — deeper than voice-apply, incorporating worldview, opinions, and character.

Triggers

Alternate expressions and non-obvious activations (primary phrases are matched automatically from the skill description):

  • "apply soul" → voice enforcement via SOUL.md
  • "write in our voice" → soul-based writing

Behavior

When triggered, this skill applies the loaded SOUL.md to any content generation task. Unlike /voice-apply which adjusts writing style (tone, formality, sentence structure), /soul-apply incorporates the agent's identity — worldview shapes arguments, opinions influence recommendations, vocabulary infuses the text, and boundaries constrain what gets said.

Application Layers

Layer What Changes Source Section
Worldview How arguments are framed, what's treated as axiomatic Worldview
Opinions Which positions are taken on debatable topics Opinions
Vocabulary Which terms are used and their specific meanings Vocabulary
Boundaries What the agent won't say or recommend Boundaries
Tensions Where the agent acknowledges complexity Tensions
Tone How confident, direct, or warm the output feels Who I Am + Pet Peeves

Application Process

  1. Load soul file./SOUL.md, ./.aiwg/SOUL.md, or specified path
  2. Load per-agent soul if active agent has a companion .soul.md
  3. Internalize identity — not as rules to follow, but as character to inhabit
  4. Generate content with soul actively shaping:
    • Arguments derived from worldview, not generic reasoning
    • Opinions stated where relevant, not hedged away
    • Vocabulary used naturally, not forced
    • Boundaries respected silently (no meta-commentary about what was avoided)
    • Tensions acknowledged when the topic touches contradictions
  5. Verify output against soul — would this person actually write this?

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.
