Adds a low-level command tree for asynchronous SQL statement management, complementing the synchronous 'tools query': databricks experimental aitools tools statement submit "SELECT ..." databricks experimental aitools tools statement get <statement_id> databricks experimental aitools tools statement status <statement_id> databricks experimental aitools tools statement cancel <statement_id> submit fires an ExecuteStatement with WaitTimeout=0s and OnWaitTimeout=CONTINUE, returning the statement_id immediately. get polls (via pollStatement from #5092) until terminal and emits rows on success or an error object on failure. status performs a single GET without polling. cancel sends CancelExecution. All four subcommands emit a uniform JSON shape {statement_id, state, warehouse_id, columns, rows, error} with omitempty so the payload only includes fields that subcommand has. Important UX nuance: 'statement get' Ctrl+C stops polling but does NOT cancel the server-side statement. Users that want server-side termination call 'statement cancel' explicitly. (This differs from 'tools query', which cancels server-side on Ctrl+C because the user invoked the synchronous path.) The pollStatement helper from #5092 is already designed to propagate ctx errors without touching the server, so 'get' inherits this behavior for free. Co-authored-by: Isaac

discover-schema previously walked tables sequentially and ran each table's three probes (DESCRIBE, sample SELECT, null counts) one after the other. For ai-dev-kit's data-exploration phase that meant warehouse-bound work was idle most of the time. Same root cause as the multi-query exploration latency that PR 2 fixed; same fix. Two layers of parallelism: 1. Tables fan out via errgroup with --concurrency (default 8). A failure on one table never aborts the others; it gets rendered inline as "Error discovering ...". 2. Within a table, DESCRIBE still runs first because the column list feeds the null-counts query. After DESCRIBE returns, the sample SELECT and null-counts probes run concurrently. The output text is assembled once both finish, preserving the existing column order (COLUMNS, SAMPLE DATA, NULL COUNTS). Switch executeSQL from the SDK's ExecuteAndWait helper to ExecuteStatement + pollStatement (the helper extracted in #5092). This brings discover-schema in line with query.go and statement.go: explicit OnWaitTimeout=CONTINUE on every call, and any future polling-helper improvement (e.g. signal handling) lands here for free. Failed states now flow through checkFailedState, which yields more specific error messages (e.g. "query failed: SYNTAX_ERROR ...") than the previous hand-rolled branch. The user-visible "SAMPLE DATA: Error - %v" / "NULL COUNTS: Error - %v" wrapping is unchanged. Add --concurrency validation matching the cmd/fs/cp.go and experimental/aitools/cmd/query.go pattern: PreRunE rejects values <= 0 with errInvalidBatchConcurrency. Tests added in discover_schema_test.go: - quoteTableName (table-driven across valid identifiers, missing parts, injection attempts, empty parts, leading-digit identifiers) - parseDescribeResult skipping metadata rows - executeSQL pins OnWaitTimeout=CONTINUE - executeSQL propagates server-reported FAILED state - executeSQL wraps transport errors - discoverTable: sample and null-count probes run concurrently after DESCRIBE (atomic peak-counter assertion) - discoverTable: a sample failure does not abort null counts - --concurrency 0 and -1 rejected at PreRunE time - invalid table name (not CATALOG.SCHEMA.TABLE) rejected at RunE validation before any API call Co-authored-by: Isaac

Refactor `executeAndPoll` in `experimental/aitools/cmd/query.go` to extract a pure `pollStatement(ctx, api, resp)` helper. The helper polls until the statement reaches a terminal state and returns the response without any signal handling, spinner, or server-side cancellation; those concerns stay in `executeAndPoll` where they belong. Also pin `OnWaitTimeout: CONTINUE` explicitly on the `ExecuteStatement` call. The SDK default happens to be CONTINUE today, but relying on it is a hidden coupling: a server-side default flip would silently break the poll loop by killing the statement before our first GET. Behavior is unchanged for the existing `query` command. Follow-up PRs (parallel batch queries, statement lifecycle command tree) will reuse the helper. Co-authored-by: Isaac

…tabricks#5093) ## Stack This PR is part of a 4-PR stack making `aitools` data exploration faster for ai-dev-kit. Each PR is independently reviewable; merge in order. 1. databricks#5092 — aitools: extract pollStatement helper and pin OnWaitTimeout *(base: `main`)* 2. **databricks#5093 — aitools: run multiple SQL queries in parallel from one query invocation** *(base: databricks#5092)* — **this PR** 3. databricks#5095 — aitools: add 'tools statement' lifecycle commands *(base: databricks#5093)* 4. databricks#5097 — aitools: parallelize discover-schema across tables and probes *(base: databricks#5095)* Use `git diff <base>...HEAD` or set the comparison base in the GitHub UI to see only this PR's changes; the default "Files changed" diff against `main` includes ancestor PRs. --- ## Why Today `databricks experimental aitools tools query` runs one SQL at a time. ai-dev-kit's data-exploration phase fires 5-10 probes per dashboard (cardinality, top values, distributions, trend viability) and they all run in series because each is a separate CLI invocation that blocks. End-to-end exploration takes about a minute when it could take seconds. Quentin already wired up a bash workaround that fans out via the raw `/api/2.0/sql/statements` endpoint with `wait_timeout=0s` and harvests results separately. This PR exposes that pattern natively so the skill can drop the hack and other CLI users get the same speed-up. ## Changes **Before:** `query` accepted at most one positional SQL or a single `--file`. Mixing the two errored. JSON output was an array of row objects. **Now:** `query` accepts any number of positional SQLs and/or repeated `--file` paths. With one input, behavior is unchanged (back-compat). With two or more, the queries run in parallel against the warehouse and the result is a JSON array of one object per input in input order: ```json [ { "sql": "SELECT count(*) FROM t", "statement_id": "01ef...", "state": "SUCCEEDED", "elapsed_ms": 412, "columns": ["count"], "rows": [["12345"]] }, { "sql": "SELECT bad_syntax", "statement_id": "01ef...", "state": "FAILED", "elapsed_ms": 87, "error": { "message": "near 'bad_syntax': syntax error", "error_code": "SYNTAX_ERROR" } } ] ``` Implementation: - New `experimental/aitools/cmd/batch.go` with `executeBatch` (errgroup with bounded parallelism) and `runOneBatchQuery`. Each goroutine submits with `OnWaitTimeout: CONTINUE`, polls via the helper from databricks#5092, and encodes its outcome into a `batchResult` struct. Failures don't abort siblings. - New `--concurrency` flag (default 8). Same value used by `cmd/fs/cp.go` for similar fan-out. Validated `> 0` in `PreRunE` (a 0 value would deadlock `errgroup.SetLimit`). - `--file` is now a repeatable string slice. Previous `--file` + positional conflict error is removed; both compose. - `resolveSQL` is replaced by `resolveSQLs` returning `[]string`. Result order is `--file` inputs first (in flag order), then positional SQLs (in arg order). - Multi-query output is JSON-only. `--output text` and `--output csv` are rejected with an actionable error before any API call. - On Ctrl+C, in-flight statements are cancelled server-side via `CancelExecution` after `g.Wait()` returns. Statements that finished normally before the cancel are left alone. - Exit code is non-zero (`root.ErrAlreadyPrinted`) when any statement failed; the JSON already contains the error detail, no extra stderr noise. ## Test plan - [x] `go test ./experimental/aitools/...` passes. - [x] `make checks` clean. - [x] `make fmt` no drift. - [x] `make lint` 0 issues. - [x] New unit tests cover: - all-succeed batch with input-order preservation - server-reported failure on one of N (others still complete) - submission-time transport error encoded into per-result error - explicit `OnWaitTimeout: CONTINUE` on every `ExecuteStatement` - staggered completion (1 slow + 2 fast) preserves input order in results - context cancellation triggers `CancelExecution` for each in-flight statement - cobra-level rejection of `--output text` and `--output csv` with multiple positionals - cobra-level rejection of `--concurrency 0` and `--concurrency -1` - `resolveSQLs` covering mixed sources, multiple files, multiple positionals, indexed-error message - [x] Manual smoke against a real warehouse: ```bash databricks experimental aitools tools query \ --warehouse <wh> --output json \ "SELECT 1" "SELECT 2" "SELECT current_timestamp()" ```

## Stack This PR is part of a 4-PR stack making `aitools` data exploration faster for ai-dev-kit. Each PR is independently reviewable; merge in order. 1. databricks#5092 — aitools: extract pollStatement helper and pin OnWaitTimeout *(base: `main`)* 2. databricks#5093 — aitools: run multiple SQL queries in parallel from one query invocation *(base: databricks#5092)* 3. **databricks#5095 — aitools: add 'tools statement' lifecycle commands** *(base: databricks#5093)* — **this PR** 4. databricks#5097 — aitools: parallelize discover-schema across tables and probes *(base: databricks#5095)* Use `git diff <base>...HEAD` or set the comparison base in the GitHub UI to see only this PR's changes; the default "Files changed" diff against `main` includes ancestor PRs. --- ## Why Quentin's ai-dev-kit skill works against synchronous `tools query`. That covers most cases, but there are workflows where the agent wants a server-side handle it can poll separately: long-running maintenance queries, parallel exploration where the agent does other work in between, and any "submit-now-harvest-later" pattern. `tools query` with a single SQL is for "I want results now." This PR adds a low-level command tree, `tools statement`, for "I want a handle." Cleaner separation than overloading `query` with `--async`/`--cancel` flags (which would be semantically forced — a `query` shouldn't manage someone else's statement_id). ## Changes Four new subcommands under `databricks experimental aitools tools statement`: ```bash # Fire and exit with a handle. databricks experimental aitools tools statement submit \ --warehouse <wh> "SELECT pg_sleep(60)" # Output: # { "statement_id": "01ef...", "state": "PENDING", "warehouse_id": "..." } # Block until terminal and emit rows. databricks experimental aitools tools statement get <statement_id> # Peek at current state without polling. databricks experimental aitools tools statement status <statement_id> # Request cancellation. databricks experimental aitools tools statement cancel <statement_id> ``` Implementation notes: - All four subcommands emit a uniform `statementInfo` JSON shape: `{statement_id, state, warehouse_id, columns, rows, error}` with `omitempty` on every field except `statement_id`. So `submit` doesn't include `columns/rows`, `cancel` doesn't include `warehouse_id`, etc. Consumer parsing is uniform. - `submit` uses `WaitTimeout: "0s"` and `OnWaitTimeout: CONTINUE` (matching the helper from databricks#5092). - `get` uses `pollStatement` (from databricks#5092) and inherits its "ctx cancellation does NOT cancel server-side" semantics. This is the **important UX difference from `tools query`**: hitting Ctrl+C on `get` stops polling but leaves the statement running on the warehouse. Use `cancel` for explicit termination. That asymmetry is intentional, since `get` is poll-only by design — the user already submitted async. - `status` does a single `GetStatementByStatementId` with no polling. - `cancel` calls `CancelExecution` and optimistically reports `state=CANCELED`. The Statements API returns no body on cancel; the actual server-side state transitions asynchronously. The `Long` help points users at `status` if they need certainty. - A shared helper `statementErrorFromStatus` populates the `error` field for every non-success terminal state (FAILED, CANCELED, CLOSED), even when the server returns no `Status.Error` payload. So skill consumers can branch on `error == null` alone instead of inspecting `state`. - Each subcommand has a small testable helper (`submitStatement`, `getStatementResult`, `getStatementStatus`, `cancelStatementExecution`) extracted from the cobra `RunE`. Tests target the helpers directly with a mock `StatementExecutionInterface`. - Parent `statement.go` registers the four subcommands and is wired into `tools.go` next to `query`, `discover-schema`, and `get-default-warehouse`. - `submit` validates input (rejects mixed --file + positional) BEFORE accessing `WorkspaceClient`, so the error surfaces cleanly without an auth or warehouse roundtrip. ## Test plan - [x] `go test ./experimental/aitools/...` passes. - [x] `make checks` clean. - [x] `make fmt` no drift. - [x] `make lint` 0 issues. - [x] New tests cover: - `submit` returns the statement_id and pins `OnWaitTimeout: CONTINUE` - `submit` wraps transport errors with `execute statement: ...` - `get` polls until terminal and assembles rows - `get` reports server-side errors in the JSON without raising a Go error - `get` ctx cancellation propagates **without** calling `CancelExecution` (the deliberate UX difference from `query`) - `get` synthesizes `error` for terminal CLOSED / FAILED with no backend payload - `status` does a single GET, no polling - `status` reports server-side errors in the JSON; running/pending stay error-free - `status` synthesizes `error` for FAILED with no backend payload - `cancel` calls `CancelExecution` and reports `state=CANCELED` - `cancel` wraps API errors - `statementErrorFromStatus` table-driven across nil, succeeded, running, failed-with-error, failed/canceled/closed-without-error - `renderStatementInfo` JSON shape (full and minimal) - cobra-level: `submit` rejects mixed --file + positional, `submit` enforces MaximumNArgs(1), `get` and `cancel` require a positional statement_id - [x] Manual smoke against a real warehouse: ```bash SID=$(databricks experimental aitools tools statement submit \ --warehouse <wh> "SELECT pg_sleep(5)" | jq -r '.statement_id') databricks experimental aitools tools statement status "$SID" databricks experimental aitools tools statement get "$SID" ```

…icks#5097) ## Stack This PR is part of a 4-PR stack making `aitools` data exploration faster for ai-dev-kit. Each PR is independently reviewable; merge in order. 1. databricks#5092 — aitools: extract pollStatement helper and pin OnWaitTimeout *(base: `main`)* 2. databricks#5093 — aitools: run multiple SQL queries in parallel from one query invocation *(base: databricks#5092)* 3. databricks#5095 — aitools: add 'tools statement' lifecycle commands *(base: databricks#5093)* 4. **databricks#5097 — aitools: parallelize discover-schema across tables and probes** *(base: databricks#5095)* — **this PR** Use `git diff <base>...HEAD` or set the comparison base in the GitHub UI to see only this PR's changes; the default "Files changed" diff against `main` includes ancestor PRs. --- ## Why `discover-schema` walked tables sequentially and ran each table's three probes (DESCRIBE, sample SELECT, null counts) one after the other. For ai-dev-kit's data-exploration phase that meant warehouse-bound work was idle most of the time. Same root cause as the multi-query exploration latency that databricks#5093 (batch query) fixed; same fix. This is a pure latency win. No new user-facing API surface, no output-shape change. ## Changes **Two layers of parallelism plus a shared statement budget:** 1. **Across tables.** The for-loop in `RunE` becomes an `errgroup.Group`. A failure on one table never aborts the others; it's rendered inline as `"Error discovering ..."` exactly as before. 2. **Within a table.** `discoverTable` still runs DESCRIBE first because the column list feeds the null-counts query. After DESCRIBE returns, the sample SELECT and null-counts probes run concurrently. Output text is assembled once both probes finish, preserving the existing `COLUMNS / SAMPLE DATA / NULL COUNTS` order. 3. **Single warehouse-statement budget.** A new `sqlGate` (chan struct{} of capacity N + statement_id tracking) wraps every `executeSQL` call. `--concurrency` (default 8) caps total in-flight statements globally, regardless of how many tables you pass. So `--concurrency 1` actually serializes statement load, not just table fan-out. **Switch `executeSQL` to use `pollStatement`** (the helper extracted in databricks#5092) instead of the SDK's `ExecuteAndWait`. Pins `OnWaitTimeout: CONTINUE`. Failed states flow through `checkFailedState`, yielding more specific error messages (e.g. `"query failed: SYNTAX_ERROR near 'oops'"`) than the previous hand-rolled branch. The user-visible `"SAMPLE DATA: Error - %v" / "NULL COUNTS: Error - %v"` wrapping is unchanged. Future polling-helper improvements land here for free. **Cancellation discipline mirroring batch.go (databricks#5093):** signal handler cancels a derived `pollCtx`; `sqlGate` records each `statement_id` post-submission; on cancellation the recorded IDs are swept via `CancelExecution` before returning `root.ErrAlreadyPrinted`. Without this, parallelism would orphan up to N×2 statements server-side on Ctrl+C. **`--concurrency` validation** mirrors `cmd/fs/cp.go` and databricks#5093: `PreRunE` rejects values <= 0 with `errInvalidBatchConcurrency`. Table-name validation also runs in `PreRunE` so malformed identifiers are rejected before `MustWorkspaceClient` runs (no unnecessary auth roundtrip on bad input). **Output unchanged** for any input that previously succeeded. Same dividers, same header/probe ordering, same per-probe error wrapping. ## Test plan - [x] `go test ./experimental/aitools/...` passes. - [x] `make checks` clean. - [x] `make fmt` no drift. - [x] `make lint` 0 issues. - [x] New unit tests in `discover_schema_test.go`: - `quoteTableName` table-driven (valid, missing parts, too many parts, injection attempts, empty parts, leading-digit identifiers, backtick in name) - `parseDescribeResult` skips metadata rows (`#`-prefixed and empty) - `sqlGate.run` pins `OnWaitTimeout: CONTINUE`, propagates FAILED state, wraps transport errors, records IDs, respects cancelled context - `cancelDiscoverInFlight` calls API per ID; empty list is a no-op - `discoverTable`: sample and null-count probes run concurrently after DESCRIBE (deterministic atomic-counter + sync.OnceFunc + channel-close barrier; sequential execution surfaces a timeout error) - `discoverTable`: a sample-probe failure does not abort null counts - `--concurrency 0` and `-1` rejected at PreRunE - Invalid table name (not `CATALOG.SCHEMA.TABLE`) and injection attempts rejected at PreRunE before any API call - [x] Manual smoke against a real warehouse: ```bash databricks experimental aitools tools discover-schema \ samples.nyctaxi.trips samples.tpch.orders samples.tpch.customer ```

The query command in
experimental/aitools/cmd/query.goworks today, but two things make it fragile and hard to reuse:ExecuteStatementrequest setsWaitTimeout: 0sbut does not setOnWaitTimeout. That relies on the SDK's default beingCONTINUE. It is today, but a flip would silently break the command: the statement would be cancelled before our first GET and we'd never see the result.This PR is a pure refactor + one explicit-default fix. No user-visible behavior change.
Changes
