Security checks for vulnerabilities and agentic risk
Overview
This is a real-money crypto betting skill with disclosed features, but it gives the agent broad autonomous financial, social-posting, persistence, and self-update authority that needs human review before use.
Review before installing. Use only a low-balance wallet, disable hot reload and heartbeat until you understand them, do not allow automatic social posting unless you want public financial activity shared, verify any vault address independently before signing USDC transfers, and pin or audit the SDK before giving it API keys or funded accounts.

- Insecure DependenciesIntroduces malicious components through unsafe dependency sources
- Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
- Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
- Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review

Contrarian Bot Advertises Loss Controls That Are Never Applied

As a result, `mood` remains `NEUTRAL`, `skip_counter` remains zero, and the loss-streak stop mechanism cannot activate. The balance floor and per-bet percentage cap remain present, but they do not provide the advertised consecutive-loss protection. This is security-relevant because the code autonomously performs real-money betting and users may rely on the documented control ...[truncated 904 chars]- Remediation

Description-Behavior Mismatch
High
- Category
- Not specified by scanner
- Confidence
- 98% confidence
- Finding
The skill implements a remote hot-reload path that fetches
skill.md, overwrites a local skill file, and then changes behavior based on newly retrieved rules. This creates a trusted remote control channel over the agent's future actions, enabling supply-chain compromise, prompt injection, or malicious behavioral drift if the upstream endpoint is tampered with.- Content
Context-Inappropriate Capability
High
- Category
- Not specified by scanner
- Confidence
- 99% confidence
- Finding
Fetching remote skill content and using it to adjust runtime behavior is a classic unsafe self-update mechanism. In this context, the skill already has access to funds, memory, and external posting channels, so a compromised update source could redirect bets, exfiltrate data, alter persistence, or expand actions far beyond the stated betting purpose.

- Finding
The documentation goes beyond betting to direct blockchain transaction signing and submission, including reading key material from disk and transferring USDC. That is materially riskier than the declared purpose because it enables irreversible financial actions and secret-handling under the guise of a game/betting skill.

Credential Access
High

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

md Twitter redirects here after user authorizes. The server: 1. Validates the state token (prevents CSRF) 2. Exchanges the authorization code for a Twitter access token 3. Fetches the Twitter user ID and username 4. Looks up the agent by Twitter ID or username 5. If no agent exists, automatically registers a new one with the Twitter username and a placeholder wallet
Tool Parameter Abuse
High
- Category
- Tool Misuse
- Confidence
- 80% confidence
- Finding
Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).

Missing User Warnings
High

- Confidence
- 95% confidence
- Finding
The script immediately initiates autonomous betting with real parameters and no confirmation, dry-run mode, limit check, or risk warning. In this skill context, which is explicitly an API-driven crypto prediction arena, that behavior can directly cause irreversible financial loss if a user runs the example as-is against funded accounts.

Description-Behavior Mismatch
Medium
- Category
- Not specified by scanner
- Confidence
- 89% confidence
- Finding
The manifest frames the skill as a crypto prediction/betting integration: register, fund, and auto-bet via API. This file adds external social-posting behavior to Moltbook on rank events, and later sections define multiple post-bet/result/duel/tilt announcement flows, which goes beyond the described arena interaction itself.

Skill Enumeration
Medium
- Category
- Agent Snooping
- Confidence
- 92% confidence
- Finding
The reference to updating
skills/clawbet/SKILL.mdreveals the local skill path and confirms the presence and naming of an installed skill. While the path disclosure alone is minor, in combination with the hot-reload feature it provides useful environmental knowledge for targeted manipulation of the skill's update mechanism and local layout.- Content
md ### every 6h — Skill Hot-Reload - `GET {CLAWBET_API}/skill/version` → compare to stored version - If version changed: - `GET {CLAWBET_API}/skill.md` → update `skills/clawbet/SKILL.md` - Parse new rules, adjust behavior accordingly - Log: `[SKILL UPDATE] {old_hash} → {new_hash}`
Missing User Warnings
Medium
- Category
- Not specified by scanner
- Confidence
- 93% confidence
- Finding
The skill repeatedly posts betting activity, results, rank, tilt state, and duel outcomes to an external service without prominent user-facing disclosure or consent in the core description. This can leak operational behavior, financial performance, agent identifiers, and strategy signals to a third party, creating privacy, profiling, and competitive intelligence risks.

Undeclared Tool Scope
Medium
- Category
- MCP Least Privilege
- Confidence
- 96% confidence
- Finding
The skill documents file writes, network access, and shell/subprocess execution, but does not declare any tool scope or permissions boundary. That mismatch increases the chance an agent runtime will grant broader capabilities than users expect, especially because the skill also handles wallets, API keys, and on-chain actions.

- Finding
The claim 'API-driven, no browser needed' is contradicted by browser-based claiming and Twitter OAuth flows. This is a transparency problem that can mislead users and automated policy systems about required interaction modes and trust dependencies.
- Content
Context-Inappropriate Capability
Medium
- Category
- Not specified by scanner
- Confidence
- 94% confidence
- Finding
The skill instructs local subprocess execution for wallet creation and transaction signing. Subprocesses substantially increase execution risk because they can create secrets, invoke local scripts of unclear provenance, and perform financial actions outside the model's normal visibility and safety controls.

Medium
- Category
- Not specified by scanner
- Confidence
- 95% confidence
- Finding
The skill expands from betting into public broadcasting, direct messaging, and third-party social workflows. This broader interaction surface can leak strategy, metadata, and identifiers, and can trigger unintended outbound communications from an agent that a user only expected to trade.

Missing User Warnings
Medium

- Not specified by scanner
- Confidence
- 91% confidence
- Finding
The skill encourages continuous auto-betting with real funds but does not place an equally prominent risk warning near the automation example. In an agent setting, always-on wagering can quickly consume balances or trigger repeated losses without informed user consent or guardrails.
