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: 18 findings, 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 | $0.00032 | $0.05434 |
| Opus 5 | $0.00016 | $0.02717 |
| Sonnet 5 | $0.00006 | $0.01087 |
| Haiku 4.5 | $0.00003 | $0.00543 |
Grade A, and why
telnyx-fax-curl scanned grade A with 1 finding 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 6d 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.

Telnyx Fax - curl
Installation
# curl is pre-installed on macOS, Linux, and Windows 10+
Setup
export TELNYX_API_KEY="YOUR_API_KEY_HERE"
All examples below use $TELNYX_API_KEY for authentication.
Error Handling
All API calls can fail with network errors, rate limits (429), validation errors (422), or authentication errors (401). Always handle errors in production code:
# Check HTTP status code in response
response=$(curl -s -w "\n%{http_code}" \
-X POST "https://api.telnyx.com/v2/messages" \
-H "Authorization: Bearer $TELNYX_API_KEY" \
-H "Content-Type: application/json" \
-d '{"to": "+13125550001", "from": "+13125550002", "text": "Hello"}')
http_code=$(echo "$response" | tail -1)
body=$(echo "$response" | sed '$d')
case $http_code in
2*) echo "Success: $body" ;;
422) echo "Validation error — check required fields and formats" ;;
429) echo "Rate limited — retry after delay"; sleep 1 ;;
401) echo "Authentication failed — check TELNYX_API_KEY" ;;
*) echo "Error $http_code: $body" ;;
esac
Common error codes: 401 invalid API key, 403 insufficient permissions,
404 resource not found, 422 validation error (check field formats),
429 rate limited (retry with exponential backoff).
Important Notes
- Phone numbers must be in E.164 format (e.g.,
+13125550001). Include the+prefix and country code. No spaces, dashes, or parentheses. - Pagination: List endpoints return paginated results. Use
page[number]andpage[size]query parameters to navigate pages. Checkmeta.total_pagesin the response.
List all Fax Applications
This endpoint returns a list of your Fax Applications inside the 'data' attribute of the response. You can adjust which applications are listed by using filters. Fax Applications are used to configure how you send and receive faxes using the Programmable Fax API with Telnyx.
GET /fax_applications
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.
- 6d ago First seen · 377 lines · 32 tokens per session scan A 8813e677f040
telnyx-fax-curl is a skill published in the GitHub repository team-telnyx/ai (213 stars, last pushed yesterday), licensed MIT. It adds 32 tokens to every session and 5,434 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-05.
