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.

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 | $0.00019 | $0.00301 |
| Opus 5 | $0.00010 | $0.00151 |
| Sonnet 5 | $0.00004 | $0.00060 |
| Haiku 4.5 | $0.00002 | $0.00030 |
Grade A, and why
deno 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
Deno
Deno v2.0 (2024/2025) focuses on Node.js Compatibility. It can now run most npm packages and package.json projects, removing the biggest barrier to entry.
When to Use
- Security: Sandbox by default. No file/net access unless explicitly allowed.
- All-in-One: Built-in linter, formatter, test runner, bundler.
- TypeScript: Native support. No config needed.
Core Concepts
Permission Model
deno run --allow-net --allow-read main.ts.
URL Imports (Legacy-ish)
import ... from "https://deno.land/...". v2 supports npm specifiers too.
Deno Deploy
The global edge network designed for Deno.
Best Practices (2025)
Do:
- Use
jsr: The new JavaScript Registry (superset of npm). - Use
deno serve: High-performance HTTP server. - Migrate Node apps: Try running
deno run main.json existing Node projects.
Don't:
- Don't rely heavily on
node_modules: Use native Deno/JSR patterns where possible for speed.

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.

deno is a skill published in the GitHub repository G1Joshi/Agent-Skills (12 stars, last pushed 7mo ago), licensed MIT. It adds 19 tokens to every session and 301 once invoked, about $0.0001 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 2026-09-03.
