sqlite — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited sqlite (Agent Skill) and scored it 82/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 2 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

The primary manifest — the file an agent reads to learn what this artifact does.
SQLite provides lightweight, serverless SQL, but its default configurations are extremely permissive and optimized for backwards compatibility rather than production rigor.
Any AI agent interacting with or scaffolding SQLite databases MUST adhere to the following strict guidelines to prevent catastrophic concurrency failures, silent data corruption, or locking issues.
Agent Routing Rule: When encountering vague requests like "set up a database", you MUST refuse to guess and ask the user for the specific engine before assuming SQLite.
SQLite only permits one writer at a time. To prevent random SQLITE_BUSY errors and enable high-performance read-while-writing:
PRAGMA journal_mode=WAL; immediately upon connection for high concurrency, unless the database is on a networked filesystem where WAL is unsafe. Ensure the -wal and -shm sidecar files are managed alongside the main .db file.PRAGMA busy_timeout=5000; so writers wait up to 5 seconds before failing.BEGIN IMMEDIATE; to grab the write lock early and prevent deadlocks in read-then-write batch patterns, but note this locks the database for all other writers.PRAGMA synchronous=NORMAL; provides the best balance of safety and speed while in WAL mode.SQLite's default type system uses "Type Affinity" (it will happily accept the string "hello" in an INTEGER column) and ignores foreign keys.
PRAGMA foreign_keys=ON; on every single new database connection. It is not persisted. Without this, ON DELETE CASCADE fails silently.STRICT to the CREATE TABLE statement (e.g., CREATE TABLE users (...) STRICT;) to enforce real data types. This is supported in SQLite 3.37.0+.TEXT (ISO8601) or INTEGER (Unix timestamp).BOOLEAN. Use INTEGER (0/1). TRUE and FALSE are just aliases.ORDER BY clauses or dynamic table names where parameterization isn't supported), validate inputs against a strict allowlist. Do not construct SQL syntax directly from user input.ALTER TABLE is extremely limited. To perform complex schema migrations, you must wrap the operation in a transaction: create a new table, copy the data over, drop the old table, and rename the new one.BEGIN; ... COMMIT;) to achieve 10x-100x speedups..db file. After bulk deletes, run VACUUM; to reclaim space. Ensure the host system has at least 2x the database size in temporary disk space. WARNING: If running in WAL mode, you MUST execute PRAGMA wal_checkpoint(TRUNCATE); before vacuuming to safely merge the journal..db file using standard OS commands, as it will corrupt if a write is in progress. Use the .backup command in the CLI, the native backup API, or VACUUM INTO 'backup.db'.~30 seconds. Free. No account. Every finding cites a rule and a line of evidence.
