sheleg-dev

A collection of seven development integrations for products that already have users, including payments, analytics, sign-in, error reporting, and website speed.

In plain words
What is it for?
Use it when adding subscription billing, cryptocurrency payments, advertising and conversion tracking, Google sign-in, other Google authentication features, Core Web Vitals improvements, or Sentry error tracking.
Why use it?
It helps connect these services to an application's own data and operating rules, including handling payment events, user-account links, consent requirements, and useful error reports.

Security

Grade A, and why

sheleg-dev 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 yesterday.

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.

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.
