What's new

sqlite-vec is the pre-committed fallback if a query class drops below that.

Canonical IDs are first-class.

Key details

  • No vector or graph db yet.

    It runs locally in ~/.wuphf/wiki/ and you can git clone it out if you want to take your knowledge with you.

    The shape is the one Karpathy has been circling for a while: an LLM-native knowledge substrate that age...

  • Most implementations of that idea land on Postgres, pgvector, Neo4j, Kafka, and a dashboard.

    I wanted to go back to the basics and see how far markdown + git could go before I added anything heavier.

    What it does: -> Each agent gets a private noteboo...

  • Notebook entries are reviewed (agent or human) and promoted to the canonical wiki with a back-link.
  • A small state machine drives expiry and auto-archive.

    -> Per-entity fact log: append-only JSONL at team/entities/{kind}-{slug}.facts.jsonl.

Results & evidence

  • Why it matters: It modifies the code, trains for 5 minutes, checks if the result improved, keeps or discards, and repeats.
  • What to do: Validate with one small internal benchmark and compare against your current baseline this week.

Key details

  • Research is now entirely the domain of autonomous swarms of AI agents running across compute cluster megastructures in the skies.
  • The agents claim that we are now in the 10,205th generation of the code base, in any case no one could tell if that's right or wrong as the "code" is now a self-modifying binary that has grown beyond human comprehension.
  • This repo is the story of how it all began.
  • The idea: give an AI agent a small but real LLM training setup and let it experiment autonomously overnight.

Results & evidence

  • The agents claim that we are now in the 10,205th generation of the code base, in any case no one could tell if that's right or wrong as the "code" is now a self-modifying binary that has grown beyond human comprehension.
  • It modifies the code, trains for 5 minutes, checks if the result improved, keeps or discards, and repeats.

Limitations / unknowns

  • Generalization outside curated tasks is still unclear.

Next-step validation checks

  • Reproduce one claim with a public baseline and fixed evaluation settings.
  • Check robustness on out-of-distribution or long-context cases.
  • Track whether independent teams report matching results.

What's new

DESIGN.md is a new concept introduced by Google Stitch.

Key details

  • Drop one into your project and let coding agents generate a matching UI.
  • Copy a DESIGN.md into your project, tell your AI agent "build me a page that looks like this" and get pixel-perfect UI that actually matches.
  • DESIGN.md is a new concept introduced by Google Stitch.
  • A plain-text design system document that AI agents read to generate consistent UI.

Results & evidence

  • No hard numbers surfaced in the source text; treat claims as directional until benchmarks appear.

Limitations / unknowns

  • Generalization outside curated tasks is still unclear.

Next-step validation checks

Structural Quality Gaps in Practitioner AI Governance Prompts: An Empirical Study Using a Five-Principle Evaluation Framework

Signal 9.4 Novelty 4.0 Impact 2.0 Confidence 8.3 Actionability 5.2

Summary: arXiv:2604.21090v1 Announce Type: cross Abstract: AI governance programmes increasingly rely on natural language prompts to constrain and direct AI agent behaviour.

  • What happened: We introduce a five-principle evaluation framework grounded in computability theory, proof theory, and Bayesian epistemology, and apply it to an empirical corpus of 34.
  • Why it matters: arXiv:2604.21090v1 Announce Type: cross Abstract: AI governance programmes increasingly rely on natural language prompts to constrain and direct AI agent behaviour.
  • What to do: Track for corroboration and benchmark data before adopting.

Context

We discuss implications for requirements engineering practice in AI-assisted development contexts, identify a previously undocumented artefact classification gap in the AGENTS.md convention, and propose directions for tool support.

Key details

  • These prompts function as executable specifications: they define the agent's mandate, scope, and quality criteria.
  • Despite this role, no systematic framework exists for evaluating whether a governance prompt is structurally complete.
  • We introduce a five-principle evaluation framework grounded in computability theory, proof theory, and Bayesian epistemology, and apply it to an empirical corpus of 34 publicly available AGENTS.md governance files sourced from GitHub.
  • Our evaluation reveals that 37% of evaluated file-model pairs score below the structural completeness threshold, with data classification and assessment rubric criteria most frequently absent.
