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.
27th October 2026CritterWatch 1.1, Bobcat 1.0, AI Skills 1.17, and a First Look at StoatOne release wave, four products: CritterWatch 1.1 with 83 MCP tools, cron schedules, a Document Explorer and a long list of scalability fixes earned on real systems; Bobcat 1.0, the successor to Storyteller and our answer for spec-driven development; AI Skills 1.17; and the first public preview of Stoat.27th October 2026Critter Stack AI Skills 1.17: One Month of Releases, Checked Against the SourceAI Skills 1.17 is the result of a review of everything Wolverine, Marten, CritterWatch, Bobcat and Stoat shipped in the last month, checked against the product source rather than the changelogs. Thirty-six skill changes, seven of them correcting advice that had quietly gone wrong, and the CritterWatch 1.1 paired updates that were waiting in 1.16.
23rd September 2026Critter Stack AI Skills 1.14: Troubleshooting Guides, and Why the Skills Pay for ThemselvesAI Skills 1.14 ships eight troubleshooting skills that decode Critter Stack exceptions from the stack trace. It's also a good excuse to make the bigger case: skills that know Wolverine's idioms produce terser code, cheaper agent sessions, and an agent that can actually reason through concurrency, parallelism, and production diagnostics.2nd September 2026Ask Your Codebase: AI Skills and the Critter Stack Command LineA recorded session pointing an AI agent at a Critter Stack codebase with nothing but the built-in CLI diagnostics and the JasperFx AI Skills — no console, no MCP server, no running fleet. Where is this message routed? What is actually durable? Why isn't the outbox working? And the new projection-run command stepping through a broken projection one event at a time.
25th August 2026NServiceBus to Wolverine using our AI SkillsThe mechanical half of an NServiceBus migration goes fine unaided. The part that goes wrong is the decision NServiceBus used to make for you -- how each endpoint listens. Here's the same question asked twice, once with the JasperFx AI Skills installed and once without.4th June 2026The Codebase Is the Prompt: Wolverine, Vertical Slices, and AI-Assisted DevelopmentWhy the Critter Stack and Wolverine are the best foundation for vertical slice architecture in the age of AI coding agents — aggressive code compression, locality of reference, and conventions encoded in AI skill files.
20th May 2026Introducing the Critter Stack AI SkillsJasperFx Software's officially curated AI Skills for the Critter Stack are now available for purchase — continuously improved guidance that helps AI coding agents write idiomatic Marten, Polecat, and Wolverine code.
