Now directly into bun https://t.co/8PNFtcjFCt

[Jordan Upton @JordanHall_dev]

I want bun to have struct support. So here a draft into Webkit. With bun looking to the future and the need the support for high preforming JavaScript. Maybe if Bun adopts then this could help push the spec forward

Stage 2 Proposal

I hope @jarredsumner still see the need for underlining support

@R_B_J @Tina4Humanity @FaceTheNation @margbrennan @Starlink Ukraine admits to using starlink and not starshield so you know.

[Jordan Upton @JordanHall_dev]

@R_B_J @Tina4Humanity @FaceTheNation @margbrennan @Starlink which is controlled by US government not starlink

THIS IS ACTUAL F*CKING GOLD

Anthropic just shared one of the best tricks for Claude Code.

The idea: run Sonnet, Haiku and Opus 5.5 together, each one doing only the job it's best at.

Opus-level judgment on every big call, without paying Opus rates for every routine turn.

You just launch Claude Code like this:

claude --model sonnet --advisor opus

here's the split:

→ Sonnet 5.5 runs the session and writes the code
→ Haiku 5.5 explores files and docs in parallel
→ Opus 5.5 stays on call as advisor for the big calls
→ you stop spending Opus on work that doesn't need it

Opus only steps in at three moments:

→ before a plan locks
→ when the same error shows up twice
→ before calling it done

Sonnet builds. Haiku explores. Opus reviews.

JEV engineering is the same move one layer down: the forks that need no thinker (which file, which tool, retry or stop) go to JEV in milliseconds, and the big models only see the ones that split

the full tree
> Sonnet 5.5 runs the main session and edits code
> search maps the repo on Haiku 5.5
> grep finds call sites on Haiku 5.5
> docs pulls the API reference on Haiku 5.5
> Opus 5.5 on call as advisor, reads the whole transcript when consulted
> JEV routes micro-forks in milliseconds

paste the tree and this prompt into Claude Code ↓

"Rebuild my Claude Code setup around this tree:
1. Run the main session on Sonnet 5.5 with Opus 5.5 as advisor.
2. Create three read-only Haiku 5.5 subagents: search (maps the repo), grep (finds call sites), docs (pulls the API reference).
3. Add one rule to CLAUDE.md: consult the advisor before locking a plan, after the same error twice, and before calling a task done.
4. Route fast deterministic forks (tool choice, path selection, retries) through JEV.
Show me every change as a diff first. No edits until I say go."

Say hello to tslaws.

You write the laws in typescript and let your agent do the rest. Supports e2e laws too.

[Jordan Upton @JordanHall_dev]

Introducing TS laws.

It's a fork fro @vercel tsc-ts to support the law sytanx. But you write the laws let your agent write the code.

Both backend and front-end working

@jarredsumner https://t.co/NUiIXmuvCn

started work on it

[Jordan Upton @JordanHall_dev]

@jarredsumner Could we have a private APIs for structs https://t.co/YRMk5hScfS

🚨 NEW: The Government’s entrepreneurship adviser has quit ahead of the Budget

“We treat [innovation and entrepreneurship] as a bit of a sideshow... that mentality is really dangerous for British business as a whole”

What do you have when your system goes down

[Jordan Upton @JordanHall_dev]

Love to test this against what we are experimenting at work. We have git compatible layer but we also use changesets and only bring files down as and when we need it.

Ideally we dont want our own solution but we struggling for diskpace and speed especially when its comes to CI. What would you need for us?

The Taliban provided better training in firearm safety than the literal UK police.

The reason why you are facing backlash is because someone who is supposed to be trusted to handle a firearm proficiently is so poorly trained but you took the pic and hit post.

@synalx Assembly

[Jordan Upton @JordanHall_dev]

@thsottiaux I had a full month of that hence i cancelled my plan. You not telling me its only just been found.

[Jordan Upton @JordanHall_dev]

@edbzn I'll fix that issue. That was my mistake.when I was doing this all by hand. Sorry I'll fix it later and publish it

[Jordan Upton @JordanHall_dev]

@edbzn Yes please if you don't mindm plus may picked up any error I didn't find in unit tests and me playing with it

[Jordan Upton @JordanHall_dev]

@evanyou Do you know like struct that's been stuck in proposal?
