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.

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 | $0.00000 | $0.00430 |
| Opus 5 | $0.00000 | $0.00215 |
| Sonnet 5 | $0.00000 | $0.00086 |
| Haiku 4.5 | $0.00000 | $0.00043 |
Grade A, and why
twilio 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 9d 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.
What it actually says
Twilio API Skill
Overview
Twilio provides programmable communication tools. This skill details the SMS and Voice APIs, emphasizing webhooks for incoming messages and TwiML for call routing.
Installation
npm install twilio
pip install twilio
Authentication
Authenticate using Account SID and Auth Token. Keep these strictly server-side.
Core Concepts
- TwiML: XML-based language that instructs Twilio on how to handle calls and SMS.
- Message SID: Unique identifier for tracking message delivery status.
Common Workflows
- Instantiate Twilio client.
- Call
messages.createwithto,from, andbody. - Poll or use status webhooks to confirm delivery.
Error Handling
Handle the TwilioRestException. Code 21211 means 'Invalid 'To' Phone Number'. Handle gracefully in the UI.
Security
Validate incoming webhooks using twilio.validateRequest to ensure requests actually originated from Twilio.
Rate Limits
Standard SMS throughput is 1 message per second per long code. Toll-free and short codes have higher limits.
Best Practices
Use Messaging Services instead of hardcoded numbers to automatically handle compliance, opt-outs, and sender ID rotation.
Troubleshooting
If international SMS fails, check your Geo-Permissions in the Twilio Console.

Why use this skill
Use this when your agent works with twilio — structured patterns beat pasted docs and prevent common hallucinations.
AI pitfalls
- Using outdated SDK or API versions from training data
- Inventing environment variable names
- Omitting error handling and retry logic
Production checklist
- Secrets in environment variables, not source code
- Error handling and logging in place
- Rate limits and timeouts configured

What ships with it
8 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 is a skill published in the GitHub repository ashish7802/awesome-api-skills (13 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 430 tokens. 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 2026-09-03.
