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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00098 | $0.03599 |
| Opus 5.5 | $0.00039 | $0.01440 |
| Sonnet 5.5 | $0.00020 | $0.00720 |
| Haiku 4.5 | $0.00010 | $0.00360 |
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-forgehas 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, usearchitecture-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 ships with it
3 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.

using-forge is a skill published in the GitHub repository d4rkNinja/arcforge (17 stars, last pushed 1mo ago), licensed MIT. It adds 98 tokens to every session and 3,599 once invoked, about $0.0004 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.
