resk-llm-ts: TypeScript LLM Security Toolkit Released
resk-llm-ts is an open-source, TypeScript-first security toolkit for LLM-powered Node.js applications published by RESK on July 10, 2026. The library provides 11 threat detectors (including injection, jailbreak, PII scanning, and exfiltration prevention), works as middleware for frameworks like Express/Hono and as an OpenAI-compatible wrapper, and is available on GitHub and npm under a GPL-3.0 license. The project targets TypeScript developers who need LLM-layer protections (prompt injection, jailbreak attempts, data leaks) typically addressed by Python tooling.
Provides a TypeScript-native open-source security toolkit that fills a developer tooling gap for LLM deployments (11 detectors and middleware/wrapper integration), useful for teams building LLM-powered apps but not a major platform policy or industry-shifting announcement.

ESLint Plugin to Catch AI Coding Mistakes
The author analyzed roughly 500 AI-generated coding mistakes and created eslint-plugin-llm-core, an ESLint plugin with 20 rules designed to catch recurring errors produced by LLM coding assistants. The plugin targets patterns such as async/await misuse (e.g., async callbacks to array methods that return Promise arrays), empty catch blocks, missing null checks, magic numbers, deep nesting, inconsistent error handling and other LLM-prone anti-patterns. Rules are educationally worded to teach correct patterns and complement typescript-eslint rather than replace it. The project is published on GitHub (pertrai1/eslint-plugin-llm-core) and npm (eslint-plugin-llm-core), with zero-config recommended rules and an install example (npm install -D eslint-plugin-llm-core). The author plans auto-fixes, broader logging-library detection, and ongoing research to validate impact on AI-generated code quality.
llm-cli-gateway Adds Upstream Tracking, Fuzzing, and Website
The llm-cli-gateway project published updates that improve resilience when wrapping multiple vendor CLIs, harden parsers against malformed output, and provide a dedicated website. Release tags v1.16.0–v1.16.2 are live; upstream-tracking and socket-hardening work (changelogged as v1.17.0 and v1.17.1) have landed on main and will ship in the next cut. The project now stores checked-in upstream contracts and a source-map TOML, offers offline and optional live upstream scans, and added a fast-check fuzzing suite targeting provider JSON/JSONL parsing, Linux /proc parsing, and CLI argument sanitization. Other supply-chain improvements include an optional Sigstore tag-signing workflow, removal of an optional Redis layer, and a dependency floor bump (Zod 4, TypeScript 6, ESLint 10). A new agent-first website is live at llm-cli-gateway.dev.
Asqav Ships TypeScript SDK on npm
Asqav published a TypeScript SDK (@asqav/sdk) on npm that mirrors its existing Python SDK and brings agent governance and tamper-evident signing to TypeScript-based AI agents. The npm package is a thin client calling api.asqav.com, exposes the same REST API and behaviour as the Python SDK, and produces ML-DSA-65 (FIPS 204) signatures anchored to Bitcoin via OpenTimestamps for auditability. The SDK is intended to integrate with TypeScript agent frameworks such as Vercel AI SDK, LangChain.js and Mastra to sign tool calls, enabling an audit trail and policy enforcement. The SDK source is available in a GitHub monorepo (MIT license) and the TypeScript and Python SDKs are version-locked at the API level while releases remain independent.
