- Show HN: Auto Dismiss Mac OS "Allow <app> to find devices on local networks?"
dontallow is a two-file Swift launchd agent for macOS 15 and later that clicks "Don't Allow" on the "find devices on local networks" prompt. It watches the UserNotificationCenter process through an Accessibility observer, supports pause and allowlist, and can decode the Local Network rule store to show orphaned rows. It explains why Chromium temp-bundle paths make the prompt recur, and gives a PPPC profile route for fleets.

ts-rust (npm package tsc-rs) is a from-scratch Rust port of Microsoft's TypeScript compiler/checker/language server (typescript-go), produced almost entirely by LLM coding agents rather than hand-written. The author first spent over $400,000 in API tokens running GPT-5.6 Sol and GPT-6 Astra in long agentic '/goal' loops, which wrote 1.3M lines of Rust but plateaued at ~84% compatibility; switching to Claude Opus 5.5 produced a working version in 10 hours and, after ~$24,000 of further API spend over two weeks, reached 100% compatibility on tested real-world projects while passing all 181,711 ported Go baseline tests. Benchmarks show the Rust port running about 1.6x faster than the Go tsc 7 compiler (though slower than Bun's native `bun check`) across dozens of open-source codebases including VS Code, TanStack Query, Sentry and T3 Code.

It also has filters by vulnerability class, an evidence viewer, JSON and ZIP exports, password-protected access with a censored view, and a SKILL.md reporting skill that lets agents write findings straight to the source folder.

Agent Control Standard (ACS) is an OWASP GenAI Security Project specification that lets a separate Guardian Agent inspect an AI agent's proposed actions before they execute and return allow/deny/modify/ask/defer over an authenticated JSON-RPC wire, with OpenTelemetry/OCSF audit trails and a CycloneDX/SPDX/SWID AgBOM inventory. The reference implementation runs Microsoft's Agent Governance Toolkit (AGT) behind the ACS contract with Bun, including host shims for Claude Code and OpenCode, and demonstrably denies a destructive `rm -rf /` command from a live coding-agent session while allowing benign ones. The project is explicit about current gaps β the wire is unauthenticated (issue #70) and the reference Guardian fails open by default (issues #32/#37) β and only 2 of 16 lifecycle hooks are evaluated live in v0.1.0.

It uses semver-precise matching against a database of 1,241+ known-compromised package versions (auto-updated daily from Datadog and Wiz Research feeds) to flag malicious preinstall/postinstall droppers (setup_bun.js, Math_Symbol.js), rogue GitHub self-hosted runners named SHA1HULUD, and ChainDrop's new IDE-persistence hooks in .claude/settings.json and .vscode/tasks.json.

It ships a reproducible Go runner with a proxy/WebSocket/MCP/A2A adapter contract, an offline validator, DSSE-signed evidence bundles, and a CI-runnable GitHub Action, and separates containment from false-positive rate as two distinct scored axes with immutable case IDs and OWASP Agentic Top 10/MITRE ATT&CK mappings. Its governance explicitly permits third parties to publish results unfavorable to the maintainer's own Pipelock product.

A public PoC repo for CVE-2026-42533, a pre-auth heap buffer overflow in nginx's two-pass string evaluation engine that occurs when a regex-based map directive using numbered captures ($1, $2) clobbers the shared r->captures state used by a regex location, causing a LEN/VALUE size mismatch. The overflow can corrupt an adjacent ngx_pool_cleanup_t structure to hijack a function pointer for RCE, or under-write to leak heap/libc pointers defeating ASLR; the repo ships exploit.py/leak.py/overflow.py plus a Docker test environment demonstrated at 10/10 reliability on Ubuntu 24.04 against nginx 0.9.6-1.30.3/1.31.2.

It also actively fetches referenced <script> bundles using the tester's live session cookies and applies a false-positive filter to suppress doc-sample and placeholder keys, making it a practical recon aid during authorized web app pentests and bug bounty work.

Numbat is a Go-based, single-binary endpoint agent from Perplexity AI that gives visibility into AI coding-agent activity (Claude Code, Codex, OpenClaw, and other CLI/IDE/gateway agents) by capturing events through local hooks, OTLP/HTTP logs, and on-disk session artifacts. It normalizes activity into one event model, evaluates it with a local CEL rule engine (including multi-step sequence rules like secret-read-then-egress), and can optionally block matched actions via synchronous pre-action hooks (deny/monitor decisions), with case bundles and SHA-256 manifests for forensic reconstruction. Example built-in rules detect cloud-metadata SSRF requests (169.254.169.254) and credential-exfiltration chains, mapped to MITRE ATT&CK technique tags.

dsh-trading is an open-source AI trading terminal built on "DeepSeek Harness" (DSH), a Cordis-based microkernel plugin ecosystem, covering crypto, US equities, China A-shares and Hong Kong stocks. Its notable design is a multi-agent team: a "master" lead agent grounds itself in a holdings ledger and user knowledge base, then decomposes work and delegates to persona-pinned subagents β a trader (trading plans/execution), an instrument-researcher (disclosures/fundamentals), and a risk-reviewer (exposure/stress scenarios) β each dispatching bundled domain "skills" and native tools for quotes, news, order books and backtesting. Every order defaults to dry-run simulation, live execution requires explicit opt-in plus interactive human approval, and headless sessions fail closed, illustrating a concrete human-approval-gated tool-use pattern for agentic systems.

It also scans public repos for cross-tenant IDOR patterns, committed secrets, an OSV.dev supply-chain check, a Dockerfile lint, and generates a CycloneDX SBOM; a companion CLI (tenant-guard) adds a live Postgres cross-tenant isolation test as a CI gate.
