Point of view. Systems are accountability. These are not tutorials.https://ucby.iohttps://ucby.io/projects/omnigent/authorshiphttps://ucby.io/projects/omnigent/authorshipWhat it means for an agent fleet to build its own platform: 200 card branches merged in a day, a five-PR chain from store to React panel in 3 hours 20 minutes, a card filed only after its dependency merged, and the batch gate that shipped inert for forty minutes. Also who actually wrote the day's four throughput fixes.Sun, 13 Sep 2026 00:00:00 GMThttps://ucby.io/projects/omnigent/deterministichttps://ucby.io/projects/omnigent/deterministicWhere an agent fleet replaces LLM turns with code: a stage executor that moves cards on stored proof, a dispatch seam that launches workers without a coordinator turn, and routing as a table lookup that names its rule. Orchestration went from 54% of tokens to 3% of daily spend. What the code owns, what the model still decides, and how you know the split was safe.Sun, 13 Sep 2026 00:00:00 GMThttps://ucby.io/projects/omnigent/reviewhttps://ucby.io/projects/omnigent/reviewHow an agent fleet's review stage decides what pass means: a deterministic pre-pass that computes contract, blast-radius, and test-adequacy facts before any model reads the diff and grades unknown unless it holds proof; a clean round that no longer routes into fixing (81% first-verdict pass against 13 to 14%); a reviewer on a different vendor; and one real round with four blocking findings.Sun, 13 Sep 2026 00:00:00 GMThttps://ucby.io/projects/omnigent/throughputhttps://ucby.io/projects/omnigent/throughputThree weeks of making an agent fleet faster, in the order it happened: the token read that found the orchestrator at 54% of spend, the deterministic transitions that took it to 3%, the context ladder that broke builders and was reversed, the timeout storm, and the day the board merged 246 cards. Each with its measurement and its caveat.Sun, 13 Sep 2026 00:00:00 GMThttps://ucby.io/writing/i-take-the-project-the-process-cant-starthttps://ucby.io/writing/i-take-the-project-the-process-cant-startA project that is taking too long is rarely short of engineers. It is short of a start. An architecture decision review board sat in design for two years; two weeks in Cursor produced a working prototype, and the team had it in prod six weeks later. Leadership supplies the cover.Tue, 08 Sep 2026 00:00:00 GMThttps://ucby.io/writing/i-dont-know-if-the-air-cover-was-realhttps://ucby.io/writing/i-dont-know-if-the-air-cover-was-realMy director answered every wild idea with ‘run with it, go for it.’ I never found out whether the cover behind him was real, and the team built like it was. Cover is local — a direct leader’s willingness, backed one level up, not an executive’s presence.Wed, 02 Sep 2026 00:00:00 GMThttps://ucby.io/writing/i-gate-on-what-a-test-suite-can-checkhttps://ucby.io/writing/i-gate-on-what-a-test-suite-can-checkThe line for an autonomous system is verifiability, not consequence. A bug fix has known inputs and a full test suite; an Architecture Decision Review Board Submit has subjective business judgment. At 10,000 lines a card, manual review is theater.Wed, 02 Sep 2026 00:00:00 GMThttps://ucby.io/writing/my-eval-is-the-health-checkhttps://ucby.io/writing/my-eval-is-the-health-checkThe eval that gates my deploys is the health check: real dependencies, a rolling error tally, per-instance stats. The orthodoxy says keep checks shallow. When an invalidation flood from another team blew up a shared Mongo, the deep check was the alarm, not the breaker.Wed, 02 Sep 2026 00:00:00 GMThttps://ucby.io/notes/cache-any-function-in-one-linehttps://ucby.io/notes/cache-any-function-in-one-lineAny function cached by a hash of its inputs — one-minute TTL, no invalidation, at hundreds of millions of calls a day.

It reads the schema version on boot and migrates under a lock.

The autonomy came from telemetry, a lineage graph, and gates, not smarter models.
