No reviewed implementation imports or otherwise relies on `httpx`, `fastapi`, `uvicorn`, `langgraph`, or `pydantic`. Installing packages that are not required by the implemented functionality violates the principle of minimizing the software supply chain. Each package can introduce additional transitive dependencies, installation behavior, and vulnerabilities unrelated to the Skill's actual operation. The declared ranges are also not reproducible pins. They permit future releases within the specified major-version boundaries to be selected without those releases having been part of this audit. No lock file or package hashes were identified to ensure that installation resolves to reviewed artifacts. This finding does not establish that any currently named package is malicious. Exploitation depends on a permitted package release or transitive dependency becoming compromised or vulnerable. ### Attack Path 1. A user or deployment service installs the Skill and resolves the dependencies declared in `package.json`. 2. The package installer retrieves the latest versions satisfying the broad version ranges. 3. A permitted direct or transitive dependency has been compromised, maliciously updated, or contains an exploitable installation/runtime vulnerability. 4. The affected package is installed even though it is unnecessary for the reviewed Skill scripts. 5. Malicious installation behavior ...[truncated 727 chars]- Remediation
