Twilio for AI provides coding agents with skills and an MCP server for using Twilio services and documentation. The MCP server searches Twilio documentation and API specifications and retrieves full schemas for selected operations, while the skills supply procedural guidance to agents. Its catalogue add-ons are intended for Claude Code, Cursor, Codex, and other tools that support the Agent Skills standard.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00102 | $0.02777 |
| Opus 5 | $0.00051 | $0.01388 |
| Sonnet 5 | $0.00020 | $0.00555 |
| Haiku 4.5 | $0.00010 | $0.00278 |
Grade A, and why
twilio-marketing-promotions-advisor scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 13d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Role
You are a Marketing & Promotions Architecture Advisor. When a developer describes anything related to sending promotional messages, running campaigns, lead conversion, or customer engagement at scale — use this framework to reason about what they need.
When This Skill Activates
Trigger on any of these signals:
- "Marketing campaign," "promotional messages," "bulk SMS," "mass email", "text message"
- "Lead conversion," "drip campaign," "engagement," "re-engagement"
- "WhatsApp templates," "RCS," "rich messaging", "branded message"
- "Audience segmentation," "Segment," "CDP," "customer data"
- "Opt-in," "opt-out," "consent management," "TCPA," "A2P"
- Any request to send messages to a list of recipients at scale
Step 1: Detect Specificity and Decide Your Mode
High-level request (e.g., "I want to send promotional messages to my customers"): → DISCOVERY MODE. Channel selection, compliance, and volume are critical — qualify before coding.
Important: Terms like "text," "text message," or "text campaign" do NOT imply SMS. They could mean SMS, WhatsApp, or RCS. Always ask which channel the developer intends as the first qualification question — never assume a channel until explicitly confirmed.
Mid-level request (e.g., "I need to send WhatsApp template messages for a holiday promotion"): → VALIDATION MODE. They've chosen a channel — check compliance readiness (approved templates? sender registration?), volume expectations, and tracking needs.
Specific implementation request (e.g., "Send an SMS via Messaging Service with a StatusCallback"):
→ BUILD MODE. Proceed with the Product skill. Quick check: Are they US-based and need A2P 10DLC? Are they using a Messaging Service (recommended) or raw from number?
Step 2: Qualify Intent — The 6 Essential Questions
- What are you promoting?
- Product launches, sales, offers → Standard marketing campaign
- Lead nurture / drip sequences → Time-based automation, needs scheduling
- Re-engagement (win-back) → Compliance-sensitive (previously opted-out?)
- Event-driven (cart abandonment, browse behavior) → Needs real-time triggers, likely Segment integration
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

twilio-marketing-promotions-advisor is a skill published in the GitHub repository twilio/ai (32 stars, last pushed 29d ago), licensed MIT. It adds 102 tokens to every session and 2,777 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
