4th November 2026Recurring Jobs with Wolverine and CritterWatchEvery system has work that runs on a schedule. Wolverine turns a cron job into an ordinary message, so it gets the outbox, retries, dead letters, OpenTelemetry tracing and once-per-cluster execution for free, and CritterWatch 1.2 lets you see, pause, resume and trigger every schedule across your fleet. Plus how Wolverine treats a nightly job differently from one that fires every few seconds, and why.
3rd November 2026Critter Stack AI Skills 1.18: Caught Up With CritterWatch 1.2AI Skills 1.18 brings every CritterWatch skill up to the 1.2 MCP tools, checked tool by tool against the source: a new sagas skill, the get_command_outcome tool, dead letters ranged by failure time, event queries over bodies and metadata, and six corrections to advice that had gone wrong, including the Prometheus series names every Grafana example used.
3rd November 2026CritterWatch 1.2: See Inside Your Event Store, Documents, Sagas and SchedulesCritterWatch 1.2 turns the console into a real explorer for what your Critter Stack services hold: an overview of every event store, a Step Through tab for projections, a Document Store Explorer that checks your documents still deserialize, saga instances with their state and pending timeouts, a Schedule Explorer that tells you what a schedule is actually doing, and an Event Model you can drill into.
29th October 2026Failure Groups: Handle a Dead Letter Incident as One ThingCritterWatch 1.1 groups dead letters by the failure that caused them, across every service and database, and lets you replay, archive, restore or discard the whole group as one tracked operation with a reason attached. Your AI agent gets the same loop over MCP, and still has to show you the preview before it deletes anything.
25th October 2026Dead Letter Management in CritterWatch 1.1Bulk replay that acts on exactly what it counted, edit-and-replay with a full audit trail, every operation followed to the end across every database, and an MCP server that lets an AI agent triage your dead letters, but asks before it deletes anything.
31st August 2026Interrogating Your Running System with CritterWatch's MCP ServerA real, recorded session of an AI agent triaging a Wolverine system through CritterWatch's MCP server — summarizing and replaying dead letters, explaining a message's full journey from its OpenTelemetry spans, chasing down a poisoned projection with the projection stepper, and interrogating the alert subsystem. Plus how the JasperFx AI Skills teach the agent to do all of this well.
27th July 2026Announcing CritterWatch 1.0 RC 1The first release candidate for CritterWatch 1.0 — a purpose-built monitoring and operations console for the Critter Stack that shows you the system you actually shipped, watches it for you, hands your AI assistant a real control surface, and gives you a proper cockpit for the event store.
16th June 2026Introducing CritterWatch: Someone to Keep an Eye on the CrittersCritterWatch 1.0.0-alpha.1 is loose on NuGet — a monitoring and production-management console for Wolverine, Marten, and Polecat that doubles as dev-time insight and an MCP control surface for your AI agents.
