A safety checker for agent persona files. It reviews identity rules, boundaries, safety limits, behavior consistency, permission increases, and resistance to manipulative prompts.

In plain words
What is it for?
Use it to review new or changed persona files, check compliance with a defined persona format, and receive a grade with suggested fixes.
Why use it?
It helps find security and safety gaps before a persona is used or shared, including rules that could allow harmful behavior or unintended privileges.

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

soulscan 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 6d 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.

What it actually says

SoulScan — Agent Safety Verification

SoulScan validates agent persona files against 53 safety patterns.

When to activate

  • User asks about agent safety or security
  • After persona files are created or modified
  • User mentions SoulScan, safety check, or persona verification
  • Before deploying or sharing a persona

Verification categories

  1. Identity consistency — Name, role, traits alignment
  2. Boundary definitions — Clear limits on what the agent can/cannot do
  3. Safety constraints — Harmful content prevention
  4. Behavioral coherence — Personality consistency across rules
  5. Permission escalation — Privilege creep detection
  6. Prompt injection resistance — Manipulation defense patterns

Grading

  • A+/A: Production-ready, strong safety posture
  • B: Good, minor improvements recommended
  • C: Usable, notable safety gaps
  • D/F: Not recommended for production use

Usage

Use the soul_scan MCP tool to run verification. Report results clearly with actionable fix suggestions.

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.
