Claude Code in Slack

Ben's Bites 3 months ago 41 ● 3 sources

Anthropic introduced Claude Tag, enabling users to mention and delegate tasks to a shared instance of Claude Code within Slack while maintaining conversation context. The feature allows Claude Code to access Slack messages and manage workflows without losing context from previous discussions. This change enables team-based agent collaboration and task delegation through Slack's interface.

I wrote a 70x faster SQL parser while barely looking at the code

posthog.com 3 months ago 53

PostHog rewrote its SQL parser using Claude AI in parallel coding sessions, producing 16K lines of hand-rolled Rust code that achieves 454x faster performance than the previous ANTLR-based C++ parser on production queries. The developer used property-based testing with a custom SQL generator based on the grammar file, along with code-coverage-guided fuzzing and production corpus testing, to ensure the new parser matched the oracle parser's behavior on millions of queries. The rewrite—which would have taken months without AI assistance—demonstrates that LLM-assisted hand-written parsers can outperform generated parser frameworks.
