SKILL.md:39installs these mutable dependency versions:bash pip install -r requirements.txtTechnical Analysis
None of the four dependencies has an exact version constraint or an integrity hash. Consequently, each installation resolves whatever package release is available from the configured package index at that time. This makes builds irreproducible and prevents users from verifying that installed artifacts are the same artifacts reviewed during the security audit.
Python packages can execute package-controlled code during installation and later during import. If a dependency account, release process, distribution artifact, package index, or configured mirror is compromised, a future installation could retrieve attacker-controlled code. This finding does not establish that any currently listed package is malicious; it identifies the absence of controls that would constrain dependency resolution to reviewed artifacts.
Attack Path
- An attacker compromises a listed dependency's release channel, package-index account, distribution artifact, or package mirror.
- The attacker publishes a malicious release under the legitimate package name.
- A user or agent follows the documented installation instruction and runs
pip install -r requirements.txt. - Because no exact versions or hashes are required, pip can select and install the attacker-controlled release.
- Malicious package code executes during installation or when the application imports the affected dependency.
- The payload operates with the privileges of the user running pip or the stock monitor.

Remediation Suggestions
- Pin every direct dependency to a reviewed exact version using
==. - Generate a lock file that also constrains transitive dependencies.
- Record cryptographic hashes for all approved distributions and install with:
bash pip install --require-hashes -r requirements.txt - Generate pinned requirements in a controlled environment using a tool such as
pip-tools. - Prefer reviewed wheel artifacts and use a trusted, access-controlled package mirror where practical.
- Add automated dependency vulnerability and provenance scanning to the release process.
- Review and update pins deliberately rather than resolving unrestricted releases during deployment.
- Pin every direct dependency to a reviewed exact version using
