Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.
NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED SECRETS_ENV_READ
Why this grade
- NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
.agents/skills/playwright-testing/references/testing-patterns.md, line 213
const response = await route.fetch(); - SECRETS_PATH_DOTENV Low
Mentions a .env file.
.agents/skills/deepseek-harness/references/operation-and-configuration.md, line 141
3. invoking-directory `.env`; - PERMISSION_SHELL_DECLARED Note
Runs shell commands, and the manifest or description says so.
scripts/check_skills.py, line 259
completed = subprocess.run( - SECRETS_ENV_READ Note
Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.
.agents/skills/setup-playwright/references/auth-and-ci-patterns.md, line 19
await page.getByLabel('Password').fill(process.env.TEST_USER_PASSWORD!);
Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.
Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.
