Quoting @therealcornpop

Simon Willison’s Weblog 3 weeks ago 7

Teleport sponsored a post featuring a TikTok quote arguing that writing scripts with AI often sounds empty or unopinionated. The post points to 13 engineers who “pressure washed” a codebase with LLMs over 90 days, emphasizing quality over quantity for finding security vulnerabilities. This shifts attention from obvious AI writing tells to how style and substance (or the lack of them) affect perceived authorship and confidence.

AI coding agents need a secrets-safe context boundary

The New Stack 3 weeks ago 12 ● 12 sources

AI coding agents can read local files and other context, and that increases the chance that API keys or other credentials are included in prompts sent to external AI services. The article cites a 94-day median time to remediate leaked secrets found in GitHub repositories, arguing agent workflows need earlier detection before data crosses the local-to-external boundary. Organizations should treat agent context as an egress surface and add deterministic, pre-submission secrets scanning and blocking/redaction controls independent of LLM judgment.
