ReviewClawScan verdict for this skill. Analyzed May 1, 2026, 5:30 AM.

Analysis

Review before installing: the skill is mostly simulated code, but it advertises real blockchain logging and smart-wallet fees without clear approval or permission boundaries.

GuidanceDo not treat this skill's printed Cardano, warranty, registration, or payment messages as proof that real on-chain or wallet actions occurred. Before using it for real claims or payments, require clear transaction verification, explicit wallet approval, declared credentials, and documented agent-collaboration trust rules.

Findings (4)

Artifact-based informational review of SKILL.md, metadata, install specs, static scan signals, and capability signals. ClawScan does not execute the skill or run runtime probes.

Abnormal behavior control

Checks for instructions or behavior that redirect the agent, misuse tools, execute unexpected code, cascade across systems, exploit user trust, or continue outside the intended task.

Human-Agent Trust Exploitation

SeverityMediumConfidenceHighStatusConcern

scripts/verify-warranty.py

tx_hash = f"cardano_tx_{proof_hash[:16]}" ... print(f"⛓️ Logged to Cardano TX: {proof['tx_hash']}")

The script fabricates a local transaction hash but prints that it was logged to Cardano, which can mislead users into believing an actual immutable blockchain record exists.

User impactA user could rely on a warranty proof or audit trail that was never actually written to a blockchain.

RecommendationClearly label simulated behavior in user-facing output, avoid success wording for actions that did not occur, and require verifiable on-chain transaction checks before claiming Cardano logging.

Tool Misuse and Exploitation

4. Charge fee via smart wallet

## Monetization
- 1% fee per verification

The default workflow includes a financial action, but the artifacts do not define user confirmation, payment recipient, spending limits, or reversal safeguards.

User impactIf connected to real wallet tooling later, an agent could treat payment as part of the normal workflow without enough user review.

RecommendationRequire explicit user confirmation before any wallet transaction, show amount and recipient, support dry-run mode, and document limits and rollback/failure behavior.

Permission boundary

Checks whether tool use, credentials, dependencies, identity, account access, or inter-agent boundaries are broader than the stated purpose.

Identity and Privilege Abuse

SKILL.md

smart wallet payments ... Charge fee via smart wallet

Smart-wallet payments imply delegated wallet/account authority, but the skill does not declare or bound the needed credential, wallet, network, or account permissions.

User impactUsers cannot tell what wallet authority would be needed or how payment privileges would be constrained.

RecommendationDeclare all required wallet/API credentials and scope them narrowly; document which account is used, what actions are allowed, and when user approval is required.

Sensitive data protection

Checks for exposed credentials, poisoned memory or context, unclear communication boundaries, or sensitive data that could leave the user's control.

Insecure Inter-Agent Communication

SeverityLowConfidenceMediumStatusNote

references/api.md

- GET /agents: Discover agents
- POST /pay: Smart wallet tx

The references describe agent discovery and service-payment endpoints but do not define authentication, agent identity verification, or data boundaries.

User impactIf real endpoints are added, users would need to know which agents are trusted and what information or payments can be sent to them.

RecommendationDocument agent identity checks, authentication, allowed data sharing, and payment authorization rules before enabling real inter-agent collaboration.
