## Findings

No check matched anything in these tool definitions.


## Changes things (2)

Creates or changes something that can be changed back. Claude Code: ask.

### `run_sql`

- The name "run_sql" says "run": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Execute a SQL query against a fresh ephemeral in-memory database built from your schema (and optional seed rows). Returns real rows (max 500, truncation flagged), column names+types, row_count, and dialect notes. Errors come back as structured JSON with type/position/suggestion — a failed query is a useful answer, not a failure of this tool. Example: schema "CREATE TABLE t(id INTEGER, name TEXT);", query "SELECT name FROM t WHERE id=1", seed {"t":[{"id":1,"name":"ada"}]} → rows [["ada"]].
```

### `run_sql_batch`

- The name "run_sql_batch" says "run": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Run up to 10 queries against the same schema+seed. Each query executes in its OWN fresh database — writes in one query are NOT visible to the next (use this for testing variants, not for multi-statement transactions). Returns an array of run_sql results in order.
```

## Only reads (3)

Looks things up and changes nothing. Claude Code: allow.

### `diff_results`

- The name "diff_results" says "diff": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Answer "do these two queries return the same thing?" — the self-check for query refactors. Executes query_a and query_b against identical fresh databases and compares result multisets (order-insensitive; order divergence reported separately when ORDER BY is present). Returns equal:boolean, row counts, and capped row-level diffs (only_in_a / only_in_b).
```

### `explain_plan`

- The name "explain_plan" says "explain": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return the engine-native query plan for a query (SQLite: EXPLAIN QUERY PLAN) plus full-table-scan warnings. Use it to check whether an index would be used before recommending one. Example: "SELECT * FROM orders WHERE status=?" on an unindexed column → plan ["SCAN orders"], warning about the full scan.
```

### `validate_sql`

- The name "validate_sql" says "validate": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Validate a SQL query against a schema WITHOUT executing it (parse + name/type binding via EXPLAIN). Returns ok with referenced tables, or a structured error: {type: unknown_column|unknown_table|syntax|..., message, position, suggestion}. The suggestion is rule-based (edit distance against your schema). Example: query "SELECT nmae FROM users" → error type unknown_column, suggestion 'did you mean "name"?'.
```
