api-26-supply-chain

api-26-supply-chain is a skill for Claude Code, Codex from vigilantshield/Claude-HunterKit. It costs 46 tokens per session (1,873 once invoked), scanned A, original, no licence file.

A guide for testing security risks in the supply chain behind APIs. This includes outside packages, services, and software delivery systems that an API depends on.

In plain words
What is it for?
Use it to assess dependency confusion, package hijacking, CI/CD pipeline attacks, trust in third-party APIs, and vulnerabilities in upstream dependencies.
Why use it?
It helps find risks such as a fake package being installed, a dependency being taken over, or an attack entering through a build or deployment process.

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

api-26-supply-chain 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 9d 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.

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.
