The boring baseline won by 6x. Here is why that is the point.https://yonk.dev/blog/six-memories-why-memory-is-hard/Wed, 03 Jun 2026 00:00:00 +0000https://yonk.dev/blog/six-memories-why-memory-is-hard/“Add memory to the agent” sounds like one feature. It is six different jobs that need three different mechanisms. Here is the map, with a concrete example for each.https://yonk.dev/blog/reading-the-grid/Tue, 02 Jun 2026 00:00:00 +0000https://yonk.dev/blog/reading-the-grid/A 150-row benchmark grid looks like the output of a robot having a stroke — until you know the three things each row tells you. A field guide to reading our RAG bake-off: read the parametric floor first, decode the system and lane columns, and ask the only two questions that matter — is it right, and what did it cost?https://yonk.dev/blog/what-actually-moves-rag-accuracy/Mon, 01 Jun 2026 00:00:00 +0000https://yonk.dev/blog/what-actually-moves-rag-accuracy/One failing LoCoMo question turned into a cross-corpus, multi-system benchmark — and a pile of retracted conclusions. Small-N runs lie, cross-vendor numbers are rarely apples-to-apples, and a correctness bug will impersonate an architecture win every time. Run the no-context baseline, 6x your sample, and diff the bytes that reach the model before you trust any RAG number.https://yonk.dev/blog/wire-memory-afternoon/Wed, 27 May 2026 00:00:00 +0000https://yonk.dev/blog/wire-memory-afternoon/The practical follow-up to the goldfish-memory post. Bring a Postgres database with pgvector and an agent that talks to users; an hour later you’ve got two-tier memory bolted on. Staging, realtime and consolidate cells, three scheduling options, three reader patterns, and an LLM fact extractor — Python and Rust both.https://yonk.dev/blog/goldfish-memory/Sun, 24 May 2026 00:00:00 +0000https://yonk.dev/blog/goldfish-memory/Agent memory has two completely different jobs — fast context for the next reply, and curated truth three weeks later — and most people try to do both with one tool. Here’s the two-tier pattern I built chunkshop’s memory layer around, the late-event bug that silently eats conversations, and why ‘just use pgvector’ isn’t the whole answer.https://yonk.dev/blog/stele-tutorial-five-minutes-then-your-agent-remembers/Sat, 23 May 2026 00:00:00 +0000https://yonk.dev/blog/stele-tutorial-five-minutes-then-your-agent-remembers/The hands-on follow-up to the why-I-built-it post. Real commands, real outputs: install Stele, wire it into your agent, store artifacts with citations, supersede facts, time-travel with as_of, stash oversized tool output, and run recall through two strategies. Five minutes to install, the rest is just typing.https://yonk.dev/blog/stele-the-memory-layer-i-couldnt-stop-building/Thu, 21 May 2026 00:00:00 +0000https://yonk.dev/blog/stele-the-memory-layer-i-couldnt-stop-building/I said the implementation needed another quarter. Three weeks later I’d shipped Stele — source-backed, time-traveling, sovereign agent memory that plugs into seven coding assistants. What it does, the three goals driving it, what’s solid on main, and what’s still wobbly. The honest version, including the parts that aren’t built yet.https://yonk.dev/projects/stele/Sun, 17 May 2026 00:00:00 +0000https://yonk.dev/projects/stele/Agentic memory implemented natively in PostgreSQL — the episodic, relational, time-anchored memory layer agents actually forget, kept in the database you already run.https://yonk.dev/blog/pg-raggraph-as-agent-memory/Tue, 12 May 2026 00:00:00 +0000https://yonk.dev/blog/pg-raggraph-as-agent-memory/Modern AI agents need three different kinds of memory and only one of them is RAG. The episodic, relational, time-anchored kind needs a graph — and pg-raggraph happens to be shaped exactly right. Tier 1 evolution awareness, retraction-aware retrieval, namespace isolation. What’s built, what’s still gap.
