Use when reviewing SQLite schema/migration changes: DDL, on-open migrations, unique indexes, insert-path dedup, ON CONFLICT DO NOTHING scope, last_insert_rowid staleness, trigger fire-time failures, UNIQUE-index NULL semantics. Core rule: verify every semantics claim against a scratch DB — never the plan, PR, or docs.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# SQLite schema & migration review Reviewing changes to SQLite DDL, on-open migrations, unique indexes, and insert-path dedup (the project storage layer and similar single-file banks). The core rule: **SQLite semantics claims get verified with a scratch DB, never accepted from the plan, the PR, or the docs** — the docs are ambiguous on `ON CONFLICT` scope and reviewed plans routinely get it wrong (one plan asserted bare DO NOTHING "swallows FK/CHECK" — it does not). ## Empirically verified semantics (scratch-DB confirmed, 2026-08) 1. **Bare `ON CONFLICT DO NOTHING` swallows ONLY UNIQUE/PK conflicts.** NOT NULL, CHECK, and FK violations still throw `IntegrityError` even with DO NOTHING. "DO NOTHING silently swallows real errors" is not a valid risk — real errors surface loudly; only intended bucket-key conflicts are ignored. 2. **`last_insert_rowid()` is STALE after a swallowed insert**: previous successful rowid on the same connection, or 0 on a fresh connection whose first statement was swallowed. Any "insert → read back by `last_insert_rowid`" pattern must switch to a business-key re-read …

How to install
mdr add arasz/ai-badger/sqlite-schema-review@sha256:53025d67fb2eeb51The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
