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 | $0.00064 | $0.02192 |
| Opus 5 | $0.00032 | $0.01096 |
| Sonnet 5 | $0.00013 | $0.00438 |
| Haiku 4.5 | $0.00006 | $0.00219 |
Grade A, and why
Bun 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 10d 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.

Bun Skill
Product Summary
Bun is an all-in-one JavaScript/TypeScript toolkit that replaces Node.js, npm, Jest, and esbuild. It ships as a single binary with four integrated tools: a fast runtime (powered by JavaScriptCore), a package manager, a test runner, and a bundler. Key files: bunfig.toml (configuration), package.json (dependencies and scripts), bun.lock (lockfile). Primary CLI commands: bun run, bun install, bun test, bun build. Bun is 4x faster than Node.js at startup and 25x faster than npm at installation. See https://bun.com/docs for complete documentation.
When to Use
- Running scripts: Execute
.ts,.tsx,.js,.jsxfiles directly without compilation overhead - Managing dependencies: Install, add, remove, or update npm packages with
bun installandbun add - Running tests: Write Jest-compatible tests with
bun testfor unit, integration, and DOM testing - Bundling code: Bundle TypeScript, JSX, CSS, and assets for browsers or servers with
bun build - Building servers: Create HTTP servers with
Bun.serve()with built-in routing, WebSocket support, and streaming - Monorepo management: Use workspaces to manage multiple packages in a single repository
- Replacing Node.js workflows: Drop-in replacement for existing Node.js projects with minimal changes

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.
- 10d ago First seen · 194 lines · 64 tokens per session scan A 2e3714da69aa
Bun is a skill published in the GitHub repository ljcl/gaggiuino-mcp (1 stars, last pushed 4d ago), licensed MIT. It adds 64 tokens to every session and 2,192 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 2026-08-31.
