think-forge

think-forge is a skill for Claude Code, Codex from d4rkNinja/arcforge. It costs 106 tokens per session (2,774 once invoked), scanned A, original, MIT.

A routing guide for choosing which ArcForge skill to use and in what order. It provides a work map without inspecting files, changing code, or carrying out the task itself.

In plain words
What is it for?
Use it when deciding where to start, selecting a skill, planning a sequence of skills, or checking whether a request has an appropriate owner.
Why use it?
It prevents work from starting under the wrong skill when a request covers several areas. It also identifies gaps where no installed skill owns part of the work.

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

think-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 today.

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 — 151 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Think Forge

Answers one question: which ArcForge skill, in which mode, in what order.

It reads the request, names the route, and stops. It does not inspect the repository, run commands, change files, or produce the domain answer.

Core principle: A route is useful before the work starts. Deciding the route and doing the work in the same breath removes the moment where the user can correct the route.

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

Active routing skill: Think Forge (`think-forge`) — route-only.

Do not paraphrase or omit it. Naming only the routed domain owner does not prove which router is active.

Routing Law

THIS SKILL RETURNS A ROUTE AND NOTHING ELSE:
1. no file is created, edited, or deleted;
2. no command, migration, deployment, or repository operation runs;
3. no domain decision is made on the owning skill's behalf;
4. no skill is described as loaded, consulted, or already run;
5. the answer ends at the route, even when the fix looks obvious.

When to Use

Use this skill when:

  • the unqualified question is where to start, which skill or mode covers this, or what order these should run in;
  • a request spans several domains and the user wants the map before committing to work;
  • a route needs a second opinion before an expensive or risky sequence begins;
  • the user wants to know whether anything in a request has no owner, or needs a skill that is not installed;
  • a plan already exists and the question is only whether the skill selection and order are right.

When Not to Use

  • When the current request explicitly asks routing to continue into inspection, review, change, or verification, use using-forge directly.
  • When a later user turn should carry an agreed route into the work, start that turn with using-forge. If this skill was explicitly invoked, name that next-turn entry point and stop; do not invoke it now.
  • When the user already named a skill and wants the work done, go to that skill. Do not spend a turn confirming a settled route.
  • When one domain plainly owns the request and neither the mode nor the order is in question, name that skill directly. Routing a single unambiguous request adds a step and no coverage.
  • When the user wants the design, the review, the change, or the evidence, route to the owning skill instead of answering here.
  • When a concrete pull request, merge request, commit range, patch, or repository diff needs findings and an approval recommendation, that is pull-request-review-gate. When an architecture artifact needs an independent approval verdict, that is architecture-review-gate.

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.

Changes

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.
