using-forge

using-forge is a skill for Codex from d4rkNinja/arcforge. It costs 98 tokens per session (3,599 once invoked), scanned A, original, MIT.

A routing guide for ArcForge work, where ArcForge is a set of skills for handling production-system tasks. It chooses the responsible skill, the work mode, and any companion skills before domain work begins.

In plain words
What is it for?
Use it for tasks involving production systems or several areas, such as checkout, signup, tenant isolation, migrations, releases, or incident follow-up.
Why use it?
It prevents multi-part requests from being handled by an incomplete or unsuitable workflow.

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

using-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 1mo 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 — 191 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Using Forge

The executing router for the ArcForge skill set. It reads an explicit route-and-continue request, decides which skill owns each surface, chooses the mode, resolves companions, puts them in a safe order, and then begins the routed first step.

This skill routes. It does not answer the domain question itself.

Core principle: A request has one owner per surface, a mode, and a companion set. Name all three before work starts, or the request gets a partial answer from whichever skill happened to activate.

Every response produced by this skill MUST begin with this exact identity line, before any other prose:

Active routing skill: Using Forge (`using-forge`) — route-and-continue.

Do not paraphrase or omit it. Naming the routed domain owner without naming this active router is incomplete.

Routing Law

NO DOMAIN WORK WITHOUT:
1. the requested outcome and the affected surfaces identified;
2. one owning skill chosen per surface, not one skill for the whole request;
3. the mode chosen from what the user actually wants: decide, inspect, apply, or prove;
4. required companions resolved before the owner they constrain, not after it finishes;
5. missing or uninstalled depth named with its exact technical ID.

When to Use

Use this skill when:

  • the user explicitly asks to route a request and continue into inspection, review, change, or verification in the same turn;
  • an explicitly executable request spans more than one domain and the full set is not obvious — checkout, signup, tenant isolation, migration, release, incident follow-up;
  • the owning skill is clear but the mode is not, and the user wants the work to continue after routing;
  • a previous answer covered one domain and silently skipped an adjacent one;
  • a companion skill is needed but which one, and in what order, is unresolved;
  • part of the needed depth may not be installed and the route must stay honest about that.

When Not to Use

  • When the user already named a skill, use that skill directly. Do not re-route a settled request.
  • When one domain plainly owns the request and no companion is in question, invoke that skill directly. Routing a single-domain request adds a step and no coverage.
  • An unqualified question about where to start, which skill or mode to use, or what order to follow defaults to think-forge.
  • When think-forge has already returned a route in the current user turn, do not re-enter this skill. Wait for an explicit later-turn request to continue into work.
  • When a concrete pull request, merge request, commit range, patch, or repository diff needs findings and an approval recommendation, use pull-request-review-gate. When an architecture artifact needs an independent approval verdict, use architecture-review-gate. Routing is not review.
  • For the domain decision itself, hand off. This skill never substitutes its own answer for the owning skill's work.

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.
