Perplexity Is Open-Sourcing Bumblebee

Perplexity has open-sourced Bumblebee, a read-only scanner that checks developer machines for risky packages, extensions, and AI tool configs during supply-chain incidents. It covers language package managers (npm, PyPI, Go, etc.), AI agent configs (MCP), VS Code-family extensions, and browser extensions. Bumblebee is designed to be safe: it reads metadata files directly without executing code, invoking package managers, or reading application source files, preventing the scanner itself from triggering attacks like postinstall scripts. It supports baseline, project, and deep scan profiles, and integrates with Perplexity's workflow where threat signals are cataloged, reviewed, and then scanned across endpoints. The tool is available as open-source Go project for macOS and Linux.

Prompt Engineering Demands Rigorous Evaluation

In the blog post “Prompt Engineering Requires Evaluation” on the Shostack + Associates website, the author argues that treating prompts for large language models (LLMs) merely as creative artefacts is insufficient. Engineering prompts properly demands structured evaluation frameworks — what the AI community calls “evals” — to test which prompt versions work better, with which models, and under which conditions. The post highlights that simply assuming a prompt is “good enough” creates risks when LLMs are integrated into production systems (e.g., for threat modeling). It advocates for measuring prompt performance, variation effects, and tool-chain dependencies (model, context, ancillary materials).  Ultimately the message is: prompt engineering should borrow disciplined practices from software engineering (versioning, testing, benchmarking) rather than relying on informal experimentation.  https://shostack.org/blog/prompt-enignieering-requires-evaluation/
