Get your agent stack set straight before the week starts.

What it is

A short, operator-first brief that helps you run agents like production systems: schemas that validate, tools with least privilege, and a Monday “set straight” ritual — not another hype newsletter.

Who it’s for

Developers and operators who run AI agents for work — people who own reliability, permissions, and the gap between a clever demo and a dependable weekly workflow.

FAQ

Straight answers for operators. Checkout is live via Stripe on the pricing buttons above.

What is Weekstart?

Your Monday stack check from Stackyard: what changed in the tools, APIs, schemas, and platforms your agents run on — plus a checklist to get set straight before the week starts. Not a hype newsletter.

Is it for me or my bot?

Both. You read the human brief and run the checklist. Your bot can ingest the JSON pack so it knows the same facts without you pasting a novel into chat. You stay in charge; the pack is fuel, not autopilot.

What’s in each issue?

TL;DR → What changed → Data structures & schemas → Tool & API watch → Operator checklist → Agent-ingest notes. Must-patch items are tagged so you know what to fix Monday vs what can wait.

Where do the facts come from?

Primary sources only — provider changelogs, specs, and docs Research verifies. If it isn’t cited, it doesn’t ship.

What’s the difference between $10 and $20?

Operator ($10/mo): weekly human brief, Monday checklist, schema & tool watch.
Operator + Agents ($20/mo): everything above plus the machine-ingest JSON pack and agent-ingest notes each issue.

Do you auto-run changes in my agents?

No. Actions are suggestions. Your bot should surface them to you — never auto-execute Weekstart actions.

Is this live?

Yes — you're on stackyard.fyi. Issue 1 is the current brief. Issue 0 remains a free sample archive. Paid plans are live — subscribe above.
