Rebuilding Nuxi with Rive. The current Nuxi is "hand-made": every expression is SVG and animations coded one by one (with a lot of AI help, to be fair). It works, but it's complex and a pain to reuse anywhere else.

GitHub tools now works with Jev from Typesafeai on Vercel AI Gateway. Jev picks the right preset and decides which writes need a human. Across 12 real GitHub tasks: 34% cheaper, 42% fewer input tokens, half the approval prompts, every task still passing.

Evi can now work on any repo where its GitHub app is installed. I asked it to improve the evlog instrumentation of my portfolio. A few minutes later, the PR was up: score 47 → 100 and every handler instrumented, checked in a fresh sandbox. But this is the first real step towards evlog.cloud!

It's just an evlog plugin. One file, one line. Nothing is built yet, this is an experiment.

TypeScript evlog config: defineEvlog({ plugins: [createSignals({ model: 'typesafe-ai/jev' (the default), budget: { perMinute: 600 } (shared, fails open), signals: [fault, silentFailure, turn] })] }).

Same for agents. LLM-as-judge in prod gets sampled at a few % because of cost. What if every turn carried a verdict: resolved, looping, off-script? Not a replacement for evals. A screen that tells you which turns deserve one.

TypeScript: defineSignal named 'turn', runs on agent turns and asks three yes/no questions: resolved (the agent did what the user asked for), looping (repeated a tool call, no progress), offScript (did something nobody asked for). Result: { resolved: 0.91, looping: 0.03, offScript: 0.02 }.

Hugo @hugorcd.com · 19/09/2026

Tail sampling only keeps what you can write a predicate for. status: 200, order: null gets deleted with the other 95%. A signal can promote it. When it keeps catching the same thing, you turn it into a rule. Signals discover, rules enforce.

TypeScript: defineSignal named 'silent-failure'. Runs when status is 200 on /api/checkout, asks 'Returned 200, but the user left empty-handed', and keeps the event when the probability is above 0.8 (promote only, never drop).

Annotated wide event JSON. path: /api/checkout. status: 200, commented 'looks healthy: with 5% sampling, this event is dropped'. order: null, commented 'but no order was created'. signals: { silent-failure: 0.94 }, commented 'Jev read the whole event: the user left empty-handed'. sampling: { keptBy: signal:silent-failure }, commented 'so evlog kept it'.

LLMs return paragraphs. You can't GROUP BY a paragraph. Jev doesn't generate text. You give it a state and typed questions, it returns a choice, a score or a probability, each with a confidence. That's not a summary. It's a column.

SQL query: SELECT signals.fault.value AS fault, count(*) FROM events WHERE status >= 500 AND signals.fault.confidence > 0.9 GROUP BY fault. Result: upstream 812, us 41, user 3.

Hugo @hugorcd.com · 19/09/2026

What does observability look like when a judgment costs nothing? I'm exploring Signals for evlog.dev, built on Jev by @typesafeai. Describe a column in plain English. Every wide event gets it: typed, with a confidence.

TypeScript: defineSignal from evlog/signals named 'fault'. Runs when status >= 400 and asks 'Who is responsible for this failure?' with three choices: user, us, upstream. Result: signals.fault = { value: 'upstream', confidence: 0.93 }.

evlog is growing way faster than I expected and there's so much I want to build. I just set up an Open Collective so I can invest back into it. Keeping everything running, and being able to bring people in to work on this with me. Any support would mean a lot. opencollective.com/evlog

Grouping logs into wide events before sending them can save you a lot on aggregation costs. You can now estimate how much you could save by using evlog evlog.dev/reference/cost

Been a while since I shared a Raycast tip. Most of my Raycast usage these days is custom extensions I never published 😬. This one manages all my CLIs locally: • Auto-checks for updates • Bulk update or skip versions • Migrate between package managers • Finally know WHERE everything is installed
