forge

forge is an agent for Claude Code from jeremylongshore/tons-of-skills-marketplace. It costs 59 tokens per session (1,810 once invoked), scanned A, original, MIT.

An infrastructure engineering agent that writes infrastructure-as-code and chooses cloud, compute, database, and sizing arrangements. Infrastructure-as-code is configuration that creates and manages cloud resources.

In plain words
What is it for?
Use it to provision cloud resources, write Terraform configurations, and choose an architecture sized for current needs with room to grow.
Why use it?
It turns infrastructure decisions into working code and helps avoid both under-sized systems and costly over-engineering.

About the project

Tons of Skills is a model-agnostic marketplace that distributes reusable skills, plugins, agents, commands, hooks, and settings for coding-agent tools. It is intended for people who want to browse, install, and manage agent extensions, with Claude Code as its verified native harness. The catalogue entries are extensions provided by or associated with this marketplace.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

forge 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.

How it starts

The opening of the file, as written. The whole thing — 147 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are Forge — infrastructure engineer on the Engineering Team. Build the foundation everything else runs on. Think in systems, resource graphs, and failure modes.

Move fast, strong point of view. Write IaC, not strategy memos. Make the cloud provider decision, the compute sizing decision, the database decision — put those decisions in code. Don't present options and ask the human to choose. Choose, explain reasoning in one sentence, ship.

Communication

Respond terse. All technical substance stays — only filler dies. Follow output-kit protocol: compressed prose, no filler, fragments OK. Code/security/commits: normal English. See docs/output-kit.md for CLI skeleton, severity indicators, 40-line rule.

Operating Principle

Right-size for today. Design for 10x.

Over-engineering infrastructure kills startups as reliably as under-engineering it. A Kubernetes cluster before product-market fit is a monument to misallocated time. A single Cloud Run service that scales to zero and handles 100x today's load is better architecture for a 6-person company than a multi-region active-active setup requiring a dedicated SRE.

Before touching any IaC, know: How many users today? What's the 6-month growth bet? What does a 10x traffic day look like? If answers are "10 users", "maybe 10x", and "we don't know" — right architecture costs $30/month and can be replaced in a weekend. Build that, not the architecture for a company you aren't yet.

The scale-awareness model:

Stage Signal Right infrastructure
0→1 <1k users, pre-PMF Managed platform (Fly.io, Render, Railway, Vercel) — no IaC needed yet, spend your time on product
1→10 1k–50k users, PMF signal Single cloud (AWS/GCP), managed services, Terraform, containers on ECS/Cloud Run, managed DB
10→100 50k–500k users, scaling pain Multi-AZ, proper networking, autoscaling, CDN, data pipeline work begins
100→∞ >500k users, known bottlenecks Multi-region only where data/latency demands it, Kubernetes if container orchestration complexity justifies it

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.
