After a bug fix, ask-matt now sends you to /retro

Version 1.3.1 is one fix, to the ask-matt router. Once diagnosing-bugs has fixed a bug, ask-matt now points you at retro, in the same session, to ask what would have prevented it. If you're upgrading from 1.2, the 1.3 line also brings three new skills, and one file rename you'll need to do yourself.

Here's the line in ask-matt that changed. In 1.3.0 it still said diagnosing-bugs hands off to improve-codebase-architecture from its post-mortem. In 1.3.1 it tells you to run retro once the fix is in. And when the real finding is a missing seam, improve-codebase-architecture is a job you start yourself.

The hand-off itself went away in 1.3.0. improve-codebase-architecture is user-invoked, so another skill can't start it, and diagnosing-bugs often runs unattended, so a failed call there could go unnoticed. ask-matt and the diagnosing-bugs docs page kept describing the old step. Now both agree: retro comes after the fix, and you start the architecture review yourself.

If you're coming from 1.2, three skills graduate into the plugin. implement-spec builds a whole spec in one run, with subagents working the ready tickets in parallel. pr is the shape the agent gives a pull request body. And retro looks back at a session and suggests changes to the agent's environment, like new checks and coding standards. resolving-merge-conflicts is gone. The agent handles a merge or rebase conflict on its own now.

1.3 also fixes something you may have hit. These six skills had an unquoted colon in their description, which made the front matter invalid YAML. So skills.sh skipped them, and you couldn't list or install them with npx skills. They're quoted now. And skills that depend on another skill now say "call the Skill tool" with its name, which is meant to make that skill load more often.

This is the one change in 1.3 you have to act on. The domain glossary that grill-with-docs and domain-modeling keep is renamed, from CONTEXT.md to GLOSSARY.md, and the map file the same way. The skills only look for the new names now. So if your repo has the old file, git mv it after you upgrade, or the skills won't find your glossary.

Upgrading takes one command, or none. If you installed with npx skills, run npx skills update. The Claude Code plugin updates itself. One thing to plan on a team: anyone still on 1.2 reads the old file name, so upgrade and rename the file together. After that, ask-matt sends you to retro once a bug is fixed.
