01
What’s new
- No skill, agent role or reference was added, removed or renamed. The catalog stays at 61 skills in 9 practice areas and 86 references.
- Skill Maker verification: a generated skill must show an observed fresh read of the studio policy and a separate observed read of the destination after publication. A claimed read, or a prepared file compared with itself, no longer counts as verification. This is the only change to skill text.
- Two documentation resources are added, on hosted module record routing and server JSON tool contracts.
02
Known limitations
- The update check and usage ping belong to the open-source Claude Code plugin. The MCP has no lifecycle hook and sends neither.
- Your assistant's capabilities and permissions still apply. Workflow delivery is not proof that a requested artifact or action completed.
03
Upgrade and migration
- No migration is required. Refresh the MCP connection to see release 1.5.2.
