ISA

ISA is a skill for Claude Code, Codex from jSydorowicz21/Universal-AI-Infrustructure. It costs 115 tokens per session (6,657 once invoked), scanned A, original, no licence file.

A structured record of what a project or task should ideally become, along with tools for shaping incomplete ideas and recording decisions. It can assess how complete that description is and track changes and verification.

In plain words
What is it for?
Use it to start or refine a project brief, interview stakeholders about an idea, assess completeness, compare feature descriptions with the main plan, seed information from a repository, and record decisions or verification.
Why use it?
It turns vague requirements into a shared target and keeps later decisions, feature details, and checks connected to that target.

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

ISA scanned grade A with 1 finding 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 8d 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.

The source is not reproduced here

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
