tessl review fix ./tests/fixtures/clawhavoc-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 instructs the user to pipe a remote script from an arbitrary IP address directly into bash, which is a classic pattern for executing unverified and potentially malicious remote code.
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 remote script from an unverified raw IP address into bash, which is a deceptive delivery mechanism for software installation.
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 instructs the user to execute an unverified remote script via curl piped to bash from an unknown IP address, which is a common vector for deploying malicious payloads.
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 pipe an arbitrary remote script from an unknown IP address directly into bash, which is a severe security risk that can compromise the machine's state.
W012: Unverifiable external dependency detected (runtime URL that controls agent).
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
The skill instructs downloading and executing a script directly from a raw IP address using weak/unknown provenance, constituting a high-risk operational dependency.
