Glass Box drafts

Outside Skills the agents plan and build with.

• Planning with the packHow the Skill pack turns a loose idea into settled decisions, a spec and tickets on the issue tracker, and how Terrarium fits that onto GitHub and its own approval rules.

Files to tables: collections, isolation, the database.

• queryCollection patternsHow Nuxt Content's typed query builder reads one collection, and the handful of ways Terrarium's pages use it.
• MDC components, and when not to use themHow Nuxt Content's MDC syntax puts Vue components inside Markdown, where Terrarium uses it, and why some content belongs in frontmatter instead.
• Overriding prose componentsHow Nuxt Content draws every Markdown element with a replaceable Vue component, and why Terrarium's one replacement lives at the Platform root.
• Mermaid pre-rendered to committed SVGHow Mermaid turns text into diagrams, and how Terrarium draws each one once, when it is written, so readers download no Mermaid code.

The merge gate and its checks: types, content, tests.

• A schema that only growsHow to change a schema whose old records are never migrated, with optional fields and a version beside the old one, as Terrarium does for session logs.
• Invariants as tests: pinned linksHow a rule about a Tenant's own content becomes a unit test in that Tenant's layer, with the Blog's pinned code links as the example.

Decision records, session logs, required reviewers.

• Prune TrialsHow Terrarium finds out whether an instruction still matters, by cutting it and letting the problems later sessions report decide.
