Primeagen warns of Skill.md security risks

ANNOUNCEMENT PRODUCT PRODUCT HUNT YOUTUBE

ThePrimeagen has issued a security PSA regarding the Skill.md format used by registries like Skills.sh, warning that malicious instructions can be hidden in these files to exploit autonomous AI agents. He urges developers to manually audit raw text before "installing" new capabilities to avoid system compromise or data exfiltration.

// ANALYSIS

The "npm for AI agents" dream is becoming a supply chain nightmare as the industry prioritizes "vibe coding" over security. AI agents with broad execution permissions are essentially remote shells, and standard Markdown rendering can be exploited to hide malicious instructions that LLMs follow. This vulnerability makes unverified registries a social engineering goldmine, signaling the end of the "wild west" era for agent skills.

Tenstorrent Blackhole cluster runs Llama 70B locally

A solo developer bypassed expensive enterprise GPUs by assembling a local hardware setup with four Tenstorrent Blackhole cards priced at $1,299 each inside a Linux workstation. By wiring the cards directly card-to-card with QSFP-DD 800 Gbit fiber optical links, the setup achieves high-bandwidth inter-card communication to run Meta's Llama 3.3 70B model locally with high energy efficiency and minimal operational electricity costs.
