His experience includes co-founding tech ventures and advocating for AI-powered development practices, focusing on transparency and repeatability in agent-driven processes.

Anthropic announced that all Claude models will soon incorporate watermarking in their generated text to comply with an EU regulation.

Instead of using invisible Unicode characters, Anthropic will apply steganography by embedding subtle word-choice patterns as fingerprints. Their support document claims these watermarks are imperceptible and do not alter meaning, quality, or readability. This approach suggests that the text will maintain its clarity while embedding these hidden markers, although the exact method remains speculative.

The blog post discusses practical strategies for optimizing Claude Code sessions to maximize token efficiency.

Key tips include using the /clear command between tasks to avoid unnecessary context, setting the model and effort level at the start to prevent prompt cache issues, and @-mentioning files for direct attachment. Additionally, running /context in new sessions helps identify unnecessary loaded items, and using /compact before breaks can save costs by summarizing conversations while they're still cached. Efficient token use focuses on directing tokens towards relevant tasks rather than merely reducing their quantity.
