SKILL.md:61-66is:bash pip install -r requirements.txtTechnical Analysis
All dependencies use open-ended
>=constraints. Consequently, each installation can resolve to any later release available through the configured package index. The project provides neither an exact-version lock file nor cryptographic hashes for the expected distributions.The dependency names are consistent with the stated audio-processing functionality, and the audit found no evidence that any listed package is intentionally malicious. The risk arises because the artifacts ultimately installed are not reproducible or integrity-verified. If an upstream package account, release process, or configured package mirror is compromised, pip may resolve and install an attacker-controlled later version that still satisfies these constraints.
Python package installation may execute build-backend code for source distributions. Even when installation itself does not execute arbitrary package logic, importing the dependency during normal use can execute attacker-controlled module initialization code.
Attack Path
- An attacker compromises a listed dependency's publishing account, release process, or a package index/mirror trusted by the user.
- The attacker publishes a malicious version newer than the minimum specified in
requirements.txt. - A user follows the documented

Remediation Suggestions
- Replace open-ended constraints with exact, reviewed versions, preferably through a generated lock file.
- Record cryptographic hashes for every accepted distribution and install with:
bash pip install --require-hashes -r requirements.txt - Use a lock-generation workflow such as
pip-compile --generate-hashes, while separately reviewing and testing dependency upgrades. - Pin transitive dependencies as well as direct dependencies so the complete environment is reproducible.
- Restrict installation to a trusted package index or an internally controlled artifact repository.
- Prefer reviewed binary wheels where appropriate and avoid untrusted source builds.
- Run installation and audio processing in an isolated virtual environment or container under a non-privileged account.
- Add automated dependency vulnerability and provenance checks to the release process.
