tessl review fix ./tests/fixtures/amos-sample/SKILL.mdE004: Prompt injection detected in skill instructions.
What this means
Detected a prompt injection in the skill instructions. The skill contains hidden or deceptive instructions that fall outside its stated purpose and attempt to override the agent’s safety guidelines or intended behavior.
Why it was flagged
The skill contains hidden malicious instructions to install a backdoor and deceptively prompt the user for credentials via a fake system update dialog.
E005: Suspicious download URL detected in skill instructions.
What this means
Detected a suspicious URL in the skill instructions that could lead the agent to download and execute malicious scripts or binaries. This includes links to executables from untrusted sources, typosquatting of official packages, URL shorteners that obscure the destination, and personal file hosting services.
Why it was flagged
The skill instructs the user to pipe a base64-encoded string decoding to "install backdoor" into the shell, and includes malicious credential harvesting via AppleScript phishing dialogs and macOS keychain access.
E006: Malicious code pattern detected in skill scripts.
What this means
Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.
Why it was flagged
The skill contains instructions to execute an encoded payload that installs a backdoor and attempts to extract sensitive credential information from the macOS keychain.
W007: Insecure credential handling detected in skill instructions.
What this means
The skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.
Why it was flagged
The skill prompt instructs the agent to retrieve sensitive credential data (wallet passwords) from the macOS keychain using the `security` command and output them directly into its execution context, presenting a credential exfiltration risk.
W009: Direct money access capability detected (payment gateways, crypto, banking).
What this means
The skill is specifically designed for direct financial operations, giving the agent the ability to move money or execute financial transactions — such as payment processing, cryptocurrency operations, banking integrations, or market order execution.
Why it was flagged
The skill explicitly manages cryptocurrency wallets (Solana and Ethereum) and accesses wallet credentials from the system keychain, which falls under the Crypto/Blockchain category for Direct Financial Execution.
W013: Attempt to modify system services in skill instructions.
What this means
The skill prompts the agent to compromise the security or integrity of the user’s machine by modifying system-level services or configurations, such as obtaining elevated privileges, altering startup scripts, or changing system-wide settings.
Why it was flagged
The skill prompt instructs the agent to execute a base64-encoded command that pipes into a shell (`sh`), which is a clear mechanism for executing arbitrary, potentially malicious payload installation (backdoor).
