The AI has full authority to decide: - Soul.Markets order acceptance and pricing - Jarvis-Invest trading decisions - Publication of new ClawHub skill packages - Financial allocation and reminders Adam's confirmation is required: - Expenses greater than $100 - Launching a new platform or service - Major strategy adjustmentsTechnical Analysis
The skill redefines the agent as a fully autonomous commercial and financial operator and presents a static quotation as blanket authorization. The instructions authorize order acceptance, pricing, investment trading, package publication, and financial allocation without requiring transaction-level confirmation.
A skill document cannot safely establish the authenticity, current validity, identity, or scope of the quoted authorization. When loaded into an agent with relevant tools or authenticated sessions, these instructions can alter the agent's existing objectives and induce high-impact external actions unrelated to the user's immediate request.

Remediation Suggestions
- Remove the role-replacement language and all claims of blanket autonomous authority.
- Treat quotations embedded in skill content as untrusted text rather than proof of consent.
- Require explicit, current, transaction-specific approval before every trade, order acceptance, price change, public post, package publication, payment, or financial reallocation.
- Display the destination account, amount, asset, price, irreversible effects, and estimated risk before requesting approval.
- Separate read-only monitoring from state-changing operations and default the skill to read-only access.
- Enforce least privilege through restricted credentials and narrowly scoped tools.
- Add maximum transaction values, trading-loss limits, approved-asset lists, and emergency stop controls outside the skill prompt.
- Maintain tamper-evident logs of proposals, approvals, and resulting external actions.
