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 | $0.00029 | $0.00510 |
| Opus 5 | $0.00015 | $0.00255 |
| Sonnet 5 | $0.00006 | $0.00102 |
| Haiku 4.5 | $0.00003 | $0.00051 |
Grade A, and why
typescript-inline-scripts 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.
What it actually says
TypeScript Inline Scripts with Bun
IMPORTANT
- ALWAYS assume Bun runtime with modern TypeScript features
- Imported npm packages will be automatically installed by Bun
- ALWAYS prefer Bun APIs where possible
Example
bun run --install=fallback - < <(cat <<'EOF'
import { z } from 'zod'
console.log(z.coerce.number().parse('5'))
EOF
)
Bun APIs Reference
Core Runtime APIs
Bun.spawn()- Process spawning and managementBun.file()- File system operations and readingBun.write()- File writing operationsfetch()- HTTP requests (Web API standard)Bun.preconnect()- URL preconnection for performance
File System
Bun.file(path)- Create file handle for reading/writingawait Bun.file(path).text()- Read file as textawait Bun.file(path).json()- Read file as JSONawait Bun.file(path).arrayBuffer()- Read file as ArrayBufferawait Bun.write(path, data)- Write data to file
Shell Commands
import { $ } from "bun"
await $`command` // Execute shell commands with template literals
const result = await $`ls -la` // Capture command output
Compression
Bun.gzipSync()- Synchronous gzip compressionBun.gunzipSync()- Synchronous gzip decompressionBun.inflateSync()- Synchronous deflate decompression
SQLite
import { Database } from "bun:sqlite"
// Database operations and SQL execution
FFI (Foreign Function Interface)
import { dlopen, CString } from "bun:ffi"
// Native library interaction
Utilities
Bun.escapeHTML()- HTML escapingBun.hash()- Hashing functionsBun.password.hash()- Password hashingBun.password.verify()- Password verification
Node.js Compatibility
- Full Node.js API support via
node:imports import { createRequire } from 'node:module'- All standard Node.js modules available
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.

typescript-inline-scripts is a skill published in the GitHub repository jahands/prompts (19 stars, last pushed 7mo ago), licensed MIT. It adds 29 tokens to every session and 510 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 2026-08-30.
