Critical
Do not install without reviewing
Security
2 findings: 1 critical severity, 1 medium severity. Installing this skill is not recommended: please review these findings carefully if you do intend to do so.
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 presence of a direct install script hosted on docs.iyear.me (used with curl | sudo bash) and a GitHub repo under an unfamiliar username (iyear) used to distribute the CLI present a high risk of malicious or tampered binaries/scripts if the sources are untrusted.
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 explicitly recommends running a remote install script with sudo ("curl -sSL ... | sudo bash") and defaults to that method on Linux, which asks the agent/user to perform an operation requiring elevated privileges and can modify the machine state.
Low
Low-risk findings.
2 low severity findings. Worth noting, but not necessarily harmful.
W011: Third-party content exposure detected (indirect prompt injection risk).
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
The skill’s runtime path uses `tdl chat export ... --with-content` to read the text content of messages from user-accessible Telegram chats, and those messages are outsider-authored by Telegram channel/group participants (with no requirement that the workflow preselects a specific outsider text item).
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's installation instructions tell users to run "curl -sSL https://docs.iyear.me/tdl/install.sh | sudo bash" and offer "go install github.com/iyear/tdl@latest", both of which fetch and execute remote code at setup time and the skill depends on tdl as a required dependency.
