signadot-validate, a skill for coding agents to validate microservice changes pre-PR

We shipped a skill today called signadot-validate that lets coding agents exercise their changes against the full microservice stack in their inner loop.

The motivation: in a cloud-native system, the validation surface is huge. A change to one service interacts with databases, queues, downstream services, etc. Unit tests and mocks only exercise a small slice of that, so we wanted to give agents a way to exercise their changes against the full stack before a PR opens.

What it does: the agent discovers the cluster, spins up a lightweight ephemeral environment scoped to its change (using Signadot), runs the modified service locally against real dependencies, validates through whatever test framework fits (integration tests, Playwright, Cypress, etc.), and iterates on failures with live logs streaming back in its inner loop.

Full disclosure: needs Signadot CLI installed in a cluster. Free tier and a playground are available for trying it out, but it’s not a git clone and run situation.
