🔬 New AI Craft
1. Flint: a visualization language that lets AI agents reliably create expressive charts
Microsoft open-sourced Flint (2.9k★), a declarative visualization language that constrains how agents generate charts — replacing "let the LLM hand-write ECharts/SVG and hope" with compile-time-validated specs (data scales, axes, animations). Unlike your Agent Plan "break down & execute" flow, Flint works at the artifact level: deterministic output that agents can't hallucinate into broken charts.

2. Lean kernel soundness bug postmortem: AI-assisted proofs stress-test verification tools themselves
An AI-assisted "disproof" of the Collatz conjecture exposed a soundness bug in Lean's kernel handling of nested inductive types; a fix landed one hour after the report (#14577). Same logic as adding AI code review to your pipeline: the stronger the generation side, the harder the verification side must be held — AI-written proofs are now pushing formal verification tools to be rigorous about themselves.

3. Explorative Modeling: a third pretraining axis for generative models
New training paradigm that adds exploration as an independent pretraining axis on top of existing generative models, monotonically improving image/video/language performance with gains that grow with scale (7%→36% with data) and reaching 6.2× sample efficiency. Rather than patching knowledge at inference like RAG, it changes the training objective so models learn to explore on their own.

🛠️ Tools & Tips
1. Cursor's usage page and CSV export now show token counts, not cost
If you track spend from the Cursor usage page, cost figures are gone — you'll need to estimate from token amounts yourself.

2. trace-file-lineage: find which script, notebook, or AI agent produced a file
Local, evidence-based lineage tracking with honest uncertainty — great for auditing AI-generated artifacts in your repos.
