twilio-verify-send-otp

Send and verify one-time passcodes (OTPs) via Twilio Verify over SMS, RCS, voice, email, or WhatsApp. Covers creating a Verify Service, sending tokens, checking submitted codes, automatic WhatsApp-to-SMS fallback, and service configuration. TOTP is supported via the Factors API (a separate family from channel-based OTP). Use this skill to add phone or email verification or two-factor authentication to any application.

Quality

Content

78%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A highly actionable, well-sequenced skill with strong code coverage and useful guardrails. Its main weakness is that nearly all content lives inline in SKILL.md with no progressive disclosure to reference files despite the length.

Suggestions

Move the Verify-vs-Programmable-Messaging comparison table and the detailed Debugging error-code reference into a separate reference file, keeping only a concise summary in SKILL.md.

Extract the full CANNOT list into a reference doc and surface the most critical gotchas (e.g., wrong code returns pending, not an error) inline.

Tighten the International OTP traffic warning paragraph to the actionable guidance (enable Fraud Guard / SMS Pumping Protection, restrict geo-permissions) and drop the explanatory framing.

DimensionReasoningScore

Conciseness

Mostly efficient with executable code blocks, tables, and a focused CANNOT list; minor over-explanation in the International OTP traffic warning paragraph and the Verify-vs-Messaging comparison could be trimmed.

4 / 5

Actionability

Provides copy-paste-ready Python and Node.js code for every common case (create service, send, check, WhatsApp, fallback, config) plus concrete error-code tables with fixes.

5 / 5

Workflow Clarity

Quickstart gives a clear Step 1–3 sequence with the status check acting as the validation checkpoint and the CANNOT list flagging the must-check-approved pitfall; minor explicit validation gaps remain.

4 / 5

Progressive Disclosure

Well-organized into sections but ~280 lines with all content inlined and no reference files; the comparison table, full debugging reference, and CANNOT list could be split into separate files for better disclosure.

Description

92%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, specific description that covers concrete actions across multiple channels and explicitly states when to use it. Trigger coverage is good but could add a few more colloquial synonyms.

DimensionReasoningScore

Specificity

Lists multiple concrete actions (send/verify OTPs, create a Verify Service, send tokens, check submitted codes, WhatsApp-to-SMS fallback, service configuration) across five channels plus TOTP, giving comprehensive coverage.

5 / 5

Completeness

Clearly states what it does and provides an explicit trigger clause ("Use this skill to add phone or email verification or two-factor authentication to any application") answering both what and when.

5 / 5

Trigger Term Quality

Includes natural terms users say ("one-time passcodes (OTPs)", "verification", "two-factor authentication", "phone or email verification"), but omits common synonyms like "login code", "auth code", or "SMS code".

4 / 5

Distinctiveness Conflict Risk

Occupies a clear niche (Twilio Verify OTP/2FA) with distinct triggers and explicit pointers to sibling Twilio skills, minimizing conflict risk with adjacent skills.
