oc-stack-forge

oc-stack-forge is a skill for Claude Code from asfbay-bit/opchain-skills. It costs 70 tokens per session (6,689 once invoked), scanned A, original, Apache-2.0.

A decision aid for choosing a software technology stack—the programming languages, frameworks, hosting, and services used to build an application. It supports platforms and frameworks such as Cloudflare Workers, Vercel, AWS, Supabase, Rails, Django, Go, and Rust.

In plain words
What is it for?
Use it to compare technologies, choose a stack, plan project structure, scaffold applications, and break feature requests into implementation sprints.
Why use it?
It helps turn a product idea or feature request into a suitable technical approach and project structure, with attention to type safety and the chosen stack.

Skill for Claude Code

Written for Claude Code: shipped in a Claude Code plugin. Also seen: positional $N argument.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is import { dispatchMobile } from "../../src/lib/pack-dispatch.js";.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

oc-stack-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 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.

How it starts

The opening of the file, as written. The whole thing — 580 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Stack Forge

On first invocation, read references/orchestrator.md and follow its welcome protocol.

Opinionated stack advisor that helps you pick the right tools and enforces type safety across whatever stack you choose. Auto-invoked by oc-app-architect during Phase 2 — you don't call it separately for new projects.

Works with any stack: Cloudflare Workers, Vercel/Next.js, AWS Lambda, Supabase, Rails, Django, Go, Rust — the decision framework is universal. The implementation patterns are stack-specific, loaded from reference docs at runtime.

How This Skill Fits the Build Pipeline

APP-ARCHITECT (planning)                TRI-DEV (building)
  Phase 2: Spec ──auto-calls──▶ oc-stack-forge decision tree
  Phase 5: Scaffold ──auto-calls──▶ oc-stack-forge project structure
                                         │
  Feature request ───────────────────────▶ /oc-feature → sprint decomposition
                                         │
                                   Planner reads feature-decomposition
                                   Generator reads stack-specific patterns
                                   Evaluator reads per-layer criteria

App-architect auto-invokes oc-stack-forge — when Phase 2 starts, oc-stack-forge's decision tree runs automatically to generate 01-tech-stack.md and 02-architecture.md. The user doesn't need to call /oc-stack-forge separately. Stack-forge reads the discovery interview results and recommends the best stack for the project's requirements.

App-architect Phase 6 uses oc-stack-forge for stack-ordered sprint decomposition regardless of stack choice.

What ships with it

60 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
