I spent some time to look into leviathan by @joshuagunnn, a BM25 index over your data for coding agents. It claims 245x fewer tokens than grep on database access. Unfortunately (Spoiler) it did not hold up in my tests :(

5 ranked results don't help with lookups and counts, so instead of a second copy of the data, a pg_trgm index would be much more effective for me. It might be helpful if your agents constantly grep through big piles of text. ~20x is not 200x, but still a good improvement.

Also not a fan of the code explosion in 0.2.0 -> 4.5k to 10.5k lines of Rust to add a bunch of unrelated stuff.

Diagrams and modelling are the next big thing in agentic coding and the hype is finally picking up.

We’re excited to announce our $15M Series A, led by @insightpartners. Passionfroot is the execution layer for creator-led growth — the way the next generation of companies reach the market. As AI makes software easy to build, distribution becomes the real moat. Buyers no longer discover products through ads or SEO; they find them through the independent voices they already trust — the creators, operators and builders they follow. Passionfroot makes working with them something any team can actually run, end to end: discovery, contracts, campaigns and global payments, unified by AI. Today we power creator-led growth for Figma, Replit, Airtable, Luma and countless category-leading AI-natives and Fortune 500s. This raise lets us open our New York office, invest deeply in the product, and grow the team across New York, Berlin and São Paulo. Huge thanks to Insight Partners for leading the round, to Creandum, Supernode and s16vc for doubling down, and to our customers for building this with us. Read the story in TechCrunch 👇

Claude CoWork now has a built-in skill to create marketing campaigns. But context matters! General AI like ChatGPT and Claude struggle to go beyond the obvious. Our Zest Agent is built to put the right information in the right place, at the right time. v1 ✅ what's next?
Creator-led GTM works. Scaling it hasn’t. Until now. 🍋 Introducing Zest, the first AI agent for creator-led GTM. From one prompt, Zest builds strategy, finds creators, runs outreach, manages campaigns, and turns results into clear next steps. Modern GTM is creator-led. With Zest, it’s finally scalable.

agents -> MCP -> CLI access -> Subagent MCPs -> ? next step: interactive (sub)agents that can communicate with the main agent. Seems like the perfect trade-off between context and composition/responsibility.
Yesterday I shipped "Agent Mode" in Sentry's MCP, which exposes the MCP's toolset as a single subagent. I wrote up a bit more about this and the initial results (13,600 tokens -> 720 tokens, 2x response time, diff ergonomics). cra.mr/subagents-with-mcp

.@passionfrootme built an AI Campaign Strategist with Gemini 2.5 Flash to scale creator marketing. It uses structured output for UI control and agentic retrieval-augmented generation (RAG), speeding up campaign launches by ~5x. Learn how: ai.google.dev/showcase/passi…

asking LLMs to optimize prompts is like asking girls for dating advice... it just isn't good.

disclaimer: limited experience, but i'm sure it also holds true for girls asking guys for advice

Would be amazing if claude code had a way to (dynamically) enable MCP usage to avoid cluttering the context. Even better - make MCP tools available only to specific subagents, so work can truly be delegated. @_catwu

Litmus test for AI agent frameworks: Does it provide proper interfaces for all major languages - if you can build great agents, you can surely automate your own integrations?
