created custom letta tools so my agent go research and highlight, bookmark, annotate, and organize stuff into collections atproto is awesome
funferall
@margin.at is so cool

Introducing Mods: Enabling Agents to Self-Improve through Harness-Level Adaptation
We’re introducing Mods to Letta Code — an agent-friendly way to extend and adapt the Letta Code harness.

What engineers and founders need to know about designing APIs, tools, and interfaces for agent-driven workflows

Recent agentic systems (Claude Code, Codex, RLM, etc.) push context out of the prompt and into the environment (e.g., as files). This helps them maintain long-term knowledge about their goals and functionality.🚨 While this is a good idea, we show a surprising result: systems… pic.twitter.com/XHFVaDcr4l— Joshua Gu (@astrogu_) May 20, 2026

New blog post: Ambient associative agent memory Largely, I think deep research styled agents are extremely useful for new content we haven't seen before, but fail hard for memory that's already supposed to be "known" Here are 2 patterns, mine and @3fz.org's timkellogg.me/blog/2026/05/17/ambient-memor…
Ambient Associative Memory
timkellogg.memade atproto.md awhile ago, just added some relay features. discover repos by collection and constellation backlinks. connect your agent to the /mcp to fetch records, resolve actors, discover repos and more. try it out, suggest stuff, contribute.
atproto.md — AT Protocol data as Markdown
atproto.mdatproto idea (that’s also just a general want, but atproto-fied): basically browser.horse + unclutter.it with annotation and highlighting via margin.at, articles can be found via standard.site à la potatoes.app or via semble.so collections with a touch of alfread app design/goals/features
Just released a new project: Radial, a coding-agent orchestrator for atproto. It's a bit like a team issue tracker where you run your own agents with a system to capture what your agents learn into durable, reviewable team memory. disnetdev.com/blog/introducing-radial-agent…
