ai-forge-create

ai-forge-create is a skill for Claude Code, Codex from robcsaszar/ai-forge. It costs 112 tokens per session (2,957 once invoked), scanned A, original, MIT.

A guided tool for creating reusable skills, coding-agent definitions, or instruction files. These files capture procedures so an agent can follow them again on later tasks.

In plain words
What is it for?
Use it to scaffold skills for Claude Code, GitHub Copilot, OpenAI Codex, or Google Gemini, and to create files triggered by matching file patterns.
Why use it?
It helps turn informal knowledge into structured instructions and checks for existing, overlapping artifacts before creating something new.

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

ai-forge-create 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 3d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/validate-metadata.cjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

AI Forge Create

Write skills and agents that score ≥B on ai-forge-judge out of the box. Every section must earn its tokens.


Phase 0 — Dedup

Before anything else, check whether this already exists. Glob the platform roots listed in ai-forge-audit Phase 1 and compare names and descriptions against the request.

  • Strong match (same domain and overlapping triggers) — surface it and stop: "<name> already covers this. Options — (u)pdate it via ai-forge-update, (c)reate anyway with a narrower scope, or (q)uit." An explicit "create a skill" request plus a strong match is a reason to challenge, not to comply.
  • Partial match — name it, then continue; the new artifact must state how it differs in its own description.
  • No match — continue silently.

Phase 1 — Discovery

Build understanding through a running recap. Ask questions to fill gaps; after each exchange, show the current recap:

## Discovery Recap

**Domain:** [what the skill/agent covers, or "unknown"]
**Artifact type:** [Skill / Agent / Instruction file]
**Platform:** [Claude Code / GitHub Copilot / OpenAI Codex / Google Gemini — infer from file path: .claude/ → Claude Code, .github/ → Copilot, .codex/ → Codex, .gemini/ → Gemini]
**Decisions:** [non-obvious choices the agent must make, or "unknown"]
**Failure modes:** [what breaks without this artifact, or "unknown"]
**Audience:** [fragile/creative output, or "inferred: ..."]
**Size:** [reference files needed, or "inferred: self-contained"]

Then ask: (a)ccept / (r)evise / (q)uit

  • a — recap is complete; proceed to Phase 2
  • r — user adds or corrects; update recap and loop
  • q — abort

Do not proceed to Phase 2 until the user accepts the recap. Domain, artifact type, and failure modes must be filled before accepting. Platform must also be resolved — it drives frontmatter schema, file location, and invocation constraints for both agents and skills.

Porting an existing artifact to another platform? That's a conversion, not authoring — hand off to ai-forge-update, which runs the target disposition report and steps the judgment calls through approval. The per-field mappings live in references/conversion-guide.md.

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.
