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 | $0.00435 |
| Opus 5 | $0.00000 | $0.00217 |
| Sonnet 5 | $0.00000 | $0.00087 |
| Haiku 4.5 | $0.00000 | $0.00044 |
Grade A, and why
sendgrid 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.
How it starts
The opening of the file, as written. The whole thing — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SendGrid API Skill
Overview
SendGrid handles transactional and marketing email delivery. This skill focuses on the @sendgrid/mail SDK and dynamic templates.
Installation
npm install @sendgrid/mail
pip install sendgrid
Authentication
Use a SendGrid API Key. Restrict API key permissions to 'Mail Send' only for production application servers.
Core Concepts
- Dynamic Templates: Handlebars-like syntax for transactional emails.
- Personalizations: Allows sending to multiple recipients with unique template data per recipient.
Common Workflows
- Set API Key.
- Construct message object with
template_idanddynamic_template_data. - Call
sgMail.send(msg).
Error Handling
Handle HTTP 401 (Invalid Key) and HTTP 403 (Domain not authenticated). Output error.response.body.errors for detailed validation messages.
Security
Ensure Sender Authentication (Domain Authentication / SPF / DKIM) is configured; otherwise emails will go to spam.
Rate Limits
SendGrid limits depend on the plan, typically supporting thousands of requests per second.
Best Practices
Do not use to arrays for bulk mailing unless you want recipients to see each other. Use multiple personalizations instead.
Troubleshooting
If emails aren't arriving, check the Activity Feed in the SendGrid dashboard for bounces or drops.

Why use this skill
Use this when your agent works with sendgrid — 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
5 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.

sendgrid 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 435 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.
