Twilio Skills provide procedural knowledge for AI coding agents — which APIs to use, in what order, and what to avoid.

Compatibility: Not stated.

Grade B

Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.

Graded by PlugVetRubric v2

Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.

Rescanned at commit 8aba46fb65dc, unchanged since the check below.

NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ

Why this grade

  • NETWORK_NO_FIXED_HOST Low

    Makes a network call whose host is not written as a fixed address.

    skills/sendgrid/twilio-sendgrid-email-send/SKILL.md, line 100 batch = requests.post("https://api.sendgrid.com/v3/mail/batch", headers=headers).json()

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    skills/sendgrid/twilio-sendgrid-email-send/SKILL.md, line 100 batch = requests.post("https://api.sendgrid.com/v3/mail/batch", headers=headers).json()

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    skills/twilio/twilio-agent-connect/SKILL.md, line 429 There are two ways to create the required Twilio services (Memory Store, Conversation Configuration, `.env` file):

  • SECRETS_ENV_READ Note

    Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.

    skills/sendgrid/twilio-sendgrid-email-send/SKILL.md, line 41 sgMail.setApiKey(process.env.SENDGRID_API_KEY);

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.

What was checked

Plain notes from the hygiene checks.

  • Permissions

    Pass

    No install-time script found, and dependencies are pinned or absent.

  • Network
