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 | $0.00134 | $0.01262 |
| Opus 5.5 | $0.00054 | $0.00505 |
| Sonnet 5.5 | $0.00027 | $0.00252 |
| Haiku 4.5 | $0.00013 | $0.00126 |
Grade A, and why
nodejs-pro-max 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 2mo 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.
How it starts

NodeJS Pro Max - Backend Generator
When User Requests Node.js / TypeScript Work
Follow this workflow for every Node.js-related task:
1. Analyze Requirements
Extract from the user's request:
- Project type: REST API, GraphQL, microservice, serverless, full-stack framework
- Domain: web, database, realtime, auth
- Scale: small project, enterprise, library
Default Stack (always use unless user specifies otherwise)
| Component | Default | Package |
|---|---|---|
| Language | TypeScript | typescript (strict mode) |
| Router | Hono | hono |
| Database | PostgreSQL | pg |
| ORM | Drizzle ORM | drizzle-orm |
| Validation | Zod | zod |
| Testing | Vitest | vitest |
| Deploy | Docker | Dockerfile |
Project structure: Domain-driven layout:
src/index.ts
src/app.ts
src/config/ — env config & setup (zod validation)
src/routes/ — API route definitions
src/controllers/ — Request handlers
src/services/ — business logic
src/models/ — TS interfaces / DB schema
src/middlewares/ — auth, error, logging
src/utils/ — helpers
package.json
tsconfig.json
Dockerfile
2. Generate Architecture System (REQUIRED for new projects)
python3 skills/nodejs/scripts/search.py "<project description>" --arch-system -p "ProjectName"
This gives you: architecture, packages, error strategy, patterns, structure, testing approach.
3. Supplement with Domain Searches
Based on the project needs, search relevant domains:
# Patterns for the task
python3 skills/nodejs/scripts/search.py "repository pattern" --domain pattern
# Package recommendations
python3 skills/nodejs/scripts/search.py "schema validation" --domain package
# Async / Concurrency patterns
python3 skills/nodejs/scripts/search.py "promise all settled" --domain async
# Performance tips
python3 skills/nodejs/scripts/search.py "event loop blocking" --domain perf
# Typescript best practices
python3 skills/nodejs/scripts/search.py "utility types" --domain typescript

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.
- 2mo ago First seen · 142 lines · 134 tokens per session scan A d60c82d88b81
nodejs-pro-max is a skill published in the GitHub repository vurakit/agentup (56 stars, last pushed 7mo ago), licensed MIT. It adds 134 tokens to every session and 1,262 once invoked, about $0.0005 per session on Opus 5.5. 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.
