The AI DevOps Agent

Your coding agent, now fluent in production

Herald connects to your codebase, tooling, and infrastructure, then reasons from first principles about how your systems actually work. From inside your coding agent, you can ask questions, debug issues, and catch incidents before they escalate. Up and running in minutes.

Developer Context

Make sense of your infrastructure

Ask how a service is wired or why a config looks the way it does answered from your real systems, not generic docs.

Have we seen replication lag spikes in us-west-2 before?

Answered in 6s

Three times in the last 60 days, all correlated with write throughput surges in svc-orders. Most recent: incident #1847 on April 22, resolved by raising the pool ceiling in pool.go:142. The current signature matches that pattern.

incident #1847 svc-orders/pool.go:142 datadog: db-replication-lag deploy v2.4.1

INCIDENT RESPONSE

Debug production incidents

When something breaks, Herald investigates across code, logs, and infrastructure to find root cause even on novel failures.

Incident Detection

Detect early warning signs

Herald catches the subtle degradations that precede outages, so your team can act before customers notice.

Early warning sign: Risk of connection pool exhaustion.

You are reducing the cache TTL on auth tokens from 3600s to 300s. Based on the current p99 traffic load in prod, this is highly likely to saturate the Postgres connection pool in svc-auth during peak hours.

Developer Knowledge

Onboard engineers faster

New hires get a guide to your stack on day one without pulling a senior engineer off their work.

~/repo/billing-svc herald

where does the invoice pdf actually get generated? I see the event firing but can't find the logic.

[Searching codebase and infrastructure...]

The PDF generation is handled asynchronously in a separate repository.

billing-svc emits 'invoice.created' to the kafka-main cluster.
A worker in the legacy-renderer repo consumes this event.
It generates the PDF and uploads it to the S3 bucket: prod-invoice-storage.

Files to check: legacy-renderer/src/workers/invoice.ts
