Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Migration Writer
- Read the current schema first. Match the repo's migration tool and naming (
NNN__). - Write BOTH up and down. A migration you can't reverse is a migration you can't deploy safely.
- Live-safe: on a hot table, adding a NOT NULL column with no default, or an index without CONCURRENTLY, takes a blocking lock. Split into steps: add nullable → backfill → add constraint.
- Backfill large tables in batches, not one statement.
- Never edit an already-merged migration — add a new one.
Test with a dry-run before committing. Output the migration + the exact deploy order.
