Engineering write-ups

How the pieces actually work.

Short, honest write-ups on the parts of Open Swarm worth explaining — the trade-offs, the things that broke, and the design decisions behind them.

Where to put the model

Your pilot worked. Production doesn't. It's usually not the prompt or the model — it's placement. A field guide to putting a deterministic check on the default path and keeping the model on what the check can't decide, with a source-verified paper behind it.

The oshal report — week of July 17–24

A numbers-first weekly status pulled from the platform's own ledgers: 174 app-store commits, 407 tickets, 554 metered LLM runs for $21.37 — and the week the platform got a clean public trunk and owner-bound remote nodes.

The desk closes the day with a video

Every session ends with a narrated recap no human edited: real figures to a deck, fresh AI-presented clips speaking that day's numbers, assembled, archived, and published — automatically. Watch the latest and browse every session since the start.

How an operations swarm finds root cause

Most "AI SRE" tools hand the model a shell and hope. The operations swarm does the opposite — prep, box-in, orchestrate: it pre-fetches the evidence, hardens the scope, then reasons over a frozen snapshot instead of poking at production.

How the trading swarm justifies a trade

A signal is not an order. Walk through how a candidate moves from the research layer, through risk sizing, to a fill that is logged and tied back to the reason it happened — and how the day closes itself out as a video.

Isolating tenants with Postgres row-level security

Isolation enforced in application code is isolation you can forget. Why the platform dropped its database superuser, moved to a least-privilege role, and let the database scope every row to its owner.

Loading 1,300+ connectors on demand

A bot does not need every API at once. How a shared connector runtime plus a marketplace lets the swarm import a public API spec and turn it into governed tools only when a task calls for it.
