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.
npx agentmods add rules/team-telnyx/ai/cursorrulesgit clone --depth 1 https://github.com/team-telnyx/aiWhat 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 | $0.00604 | $0.00604 |
| Opus 5 | $0.00302 | $0.00302 |
| Sonnet 5 | $0.00121 | $0.00121 |
| Haiku 4.5 | $0.00060 | $0.00060 |
Grade A, and why
cursorrules 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 2d 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.

Cursor rules — team-telnyx/ai
Operating instructions for the Cursor agent working in this repo.
This file is the legacy single-file convention. The MDC equivalent
lives at .cursor/rules/main.mdc. The canonical source of truth
for everything below is AGENTS.md at the repo root — keep these
rules in sync with it when changing project-wide guidance.
What this repo is
Telnyx AI — agent toolkits, plugins for Claude Code / Cursor / Gemini /
OpenCode, an MCP proxy, 235+ agent skills, and operational guides.
The skills under skills/ are the source of truth; they are synced to
providers/{claude,cursor}/plugin/skills/ via scripts/sync-skills.sh.
Hard rules (don't break these)
- Don't hand-edit files under
providers/claude/plugin/skills/orproviders/cursor/plugin/skills/— they are generated. Edit the source underskills/and run./scripts/sync-skills.sh. - Don't run
npm installat the repo root. Each package has its ownpackage.jsonandnode_modules/. Install per-package:cd cli && npm ci,cd tools/typescript && npm ci, etc. - Don't introduce a root-level test runner. Each package owns its own tests. Run only the package you touched.
- Don't commit credentials, API keys, or
.envfiles. Use the patterns in existing.env.examplefiles.
Per-package commands
cli/:cd cli && npm testtools/python/:cd tools/python && pytesttools/typescript/:cd tools/typescript && npm testtools/mcp/:cd tools/mcp && npm run buildguides/:npm run test:guidesfrom repo root- Guides API tests:
npm run test:guides-apifrom repo root
Code style
- TypeScript: ES2020+, strict mode, ESM where the package supports it.
- Python: 3.10+, PEP 8, type hints required for public functions.
- Markdown: GitHub-flavored. ATX headings (
#), no underline headings. - One concern per PR. Keep skill regenerations in the same PR as the
skill source change (run
./scripts/sync-skills.shand commit both).
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.

cursorrules is a cursor rule published in the GitHub repository team-telnyx/ai (212 stars, last pushed 5d ago), licensed MIT. It adds 604 tokens to every session, about $0.0030 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.
