package.json:32-34:json "dependencies": { "requests": "^2.28.0" }SKILL.md:117-120:bash ### Installation Dependencies ```bash pip3 install requeststext ### Technical Analysis The executable imports the Python `requests` library, but the project declares `requests` under the npm `dependencies` field. npm and Python Package Index dependencies are unrelated ecosystems; therefore, an npm installation resolves an npm package named `requests`, not the Python library used by `tools/finance_data.py`. This mismatch can cause package tooling to download and execute an unintended component. If the resolved npm package or one of its transitive dependencies contains lifecycle scripts, those scripts may execute during `npm install` with the privileges of the user or automation account performing the installation. The documented Python installation also uses `pip3 install requests` without an exact version, lock file, or cryptographic hashes. Consequently, installations are not reproducible and may retrieve a different release than the version reviewed by the project maintainer. ### Attack Path 1. A user, CI workflow, or Skill installation platform processes `package.json` and runs `npm install`. 2. npm interprets `"requests": "^2.28.0"` as an npm package requirement rather than a Python dependency. 3. npm downloads the matching package and its transitive dependencies from the configured npm registry. 4. Any permitted dependency lifecycle scripts execute under the installer account. 5. A compromised or malicious dependency could access files, environment variables, network resources, and other capabilities available to that accou ...[truncated 1236 chars]- Remediation

Remediation Suggestions
-
Remove the npm dependency because the executable uses Python rather than Node.js:
json "dependencies": {}If Node.js is not required at all, remove
package.jsonor retain it only as metadata without npm dependencies or installation hooks. -
Declare the Python dependency in a Python-native dependency file, such as
requirements.txtorpyproject.toml. -
Pin the dependency to an exact, reviewed version rather than using an unconstrained installation command:
text requests==<reviewed-version> -
Generate and verify cryptographic hashes for the package and its transitive dependencies. For example, use a locked requirements file and install with:
bash python3 -m pip install --require-hashes -r requirements.lock -
Commit the lock file to source control and update it through a controlled dependency-review process.
-
Use an isolated virtual environment and avoid installing dependencies as root or into the system Python environment.
-
In CI, restrict package installation network access, use a trusted internal package mirror where appropriate, disable unnecessary npm lifecycle scripts, and grant installation jobs only the minimum required credentials.
