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 | $0.00053 | $0.00365 |
| Opus 5 | $0.00026 | $0.00182 |
| Sonnet 5 | $0.00011 | $0.00073 |
| Haiku 4.5 | $0.00005 | $0.00036 |
Grade A, and why
deno-bun-runtime 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 5d 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 & Bun Runtimes
Next-generation JS/TS runtimes with built-in tooling and superior performance.
Comparison
| Feature | Node.js | Deno 2 | Bun |
|---|---|---|---|
| TypeScript | Needs build | Native | Native |
| Package Manager | npm/pnpm | npm compatible | bun install (fastest) |
| Test Runner | Jest/Vitest | Built-in | Built-in |
| Bundler | Webpack/Vite | Built-in | Built-in (fastest) |
| Security | Unrestricted | Permissions model | Unrestricted |
| HTTP Server | Express/Fastify | Deno.serve | Bun.serve |
| Speed | Baseline | 1.5-2x faster | 3-4x faster |
Deno 2 Key Features
- npm compatibility: Import npm packages directly
- Permissions:
--allow-net,--allow-read,--allow-env - LSP: Built-in language server
- Deploy: Deno Deploy for edge computing
Bun Key Features
- Speed: Fastest JS runtime, built on JavaScriptCore
- All-in-one: Runtime + bundler + test runner + package manager
- Node.js compatible: Drop-in replacement for most Node.js code
- SQLite: Built-in SQLite support
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-bun-runtime is a skill published in the GitHub repository hoangatg/ai-agent-toolkit (1 stars, last pushed 5mo ago), licensed MIT. It adds 53 tokens to every session and 365 once invoked, about $0.0003 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.
