From ad6a2e540d9c14617f0d0b6075be85b4ba709325 Mon Sep 17 00:00:00 2001 From: rahulmahadik Date: Thu, 20 Aug 2026 11:39:37 +0800 Subject: [PATCH 1/7] Say what the AI provider said, and offer only models that answer Listing models swallowed every HTTP error and returned an empty list, so a rejected key, a rate limit and an outage were indistinguishable from a provider with no models. The provider's own sentence now reaches the reader. Of the thirteen models one provider lists, six cannot hold a conversation, and the list is alphabetical, so a broken one sat where the user picks: the query then failed after the model list had looked healthy. Speech, transcription and classifier models are no longer offered. Reasoning models narrate before they answer. That monologue was shown as the query's description, and through Explain and the schema answers, which never pass through the SQL extractor. It is now removed at the client boundary and filtered out of the token stream as it arrives, so a streaming host no longer forwards it live. A tag that appears inside an answer is left alone. A hosted provider configured with a local base URL is refused rather than sent the API key. Leaving a local provider's base URL in place made "hosted" requests go to this machine, answer without a key, and report success; the stale setting is now cleared when settings open. The refusal never echoes the URL, which can embed credentials. Settings ask for the key before the model, so fetching models has what it needs, and Test Provider is renamed Test Connection and runs once a model is chosen. --- packages/browser-extension/src/listModels.ts | 10 +- .../browser-extension/src/options/main.tsx | 2 +- .../browser-extension/test/listModels.test.ts | 36 ++++++ packages/core/src/extract.ts | 63 ++++++++++- packages/core/src/llm.ts | 19 +++- packages/core/src/providers.ts | 34 +++++- packages/core/test/reasoning-strip.test.ts | 92 +++++++++++++++ .../rahulmahadik/asksql/ide/engine/Extract.kt | 8 +- .../asksql/ide/llm/AnthropicClient.kt | 3 +- .../asksql/ide/llm/BaseUrlGuard.kt | 2 + .../asksql/ide/llm/GeminiClient.kt | 3 +- .../rahulmahadik/asksql/ide/llm/LlmClient.kt | 98 +++++++++++++++- .../asksql/ide/llm/OpenAiCompatibleClient.kt | 28 ++++- .../asksql/ide/settings/AskSqlConfigurable.kt | 101 +++++++++++++---- .../asksql/ide/engine/ReasoningStripTest.kt | 48 ++++++++ .../asksql/ide/llm/ListModelsErrorTest.kt | 105 ++++++++++++++++++ .../asksql/ide/llm/LlmClientsTest.kt | 85 ++++++++++++++ packages/vscode/src/models.ts | 10 +- packages/vscode/test/models.test.ts | 35 ++++++ 19 files changed, 732 insertions(+), 50 deletions(-) create mode 100644 packages/core/test/reasoning-strip.test.ts create mode 100644 packages/jetbrains/src/test/kotlin/com/rahulmahadik/asksql/ide/engine/ReasoningStripTest.kt create mode 100644 packages/jetbrains/src/test/kotlin/com/rahulmahadik/asksql/ide/llm/ListModelsErrorTest.kt diff --git a/packages/browser-extension/src/listModels.ts b/packages/browser-extension/src/listModels.ts index c6f8afd..a67363a 100644 --- a/packages/browser-extension/src/listModels.ts +++ b/packages/browser-extension/src/listModels.ts @@ -11,7 +11,15 @@ import { ensureProviderOriginAccess } from './providerAccess.js'; const LISTABLE_HOSTED: ReadonlySet = new Set(['openai', 'groq', 'nvidia']); const MODEL_LOOKUP_TIMEOUT_MS = 10_000; -const isNotChatModel = (name: string): boolean => /embed|embedding|rerank|retriever|[-/]parse$|\bocr\b/i.test(name); +/** + * Listed beside chat models but rejected by /chat/completions.

Walked as fields, every address became a column NAME, and a name is not removed by the cell-value opt-in, which strips sampled values only. Those names reached the prompt on the default path. A record repeats its fields across documents; a map does not, so a parent whose children do not recur is described by its shape instead. The judgement is per child, so a summary field beside the keys keeps its name, and shape decides before reuse, so an address goes whatever its frequency. Four shapes needed separating from a real record and are covered by tests: a root-level map, a key containing dots whose first segment matches a real field, a map nested in an array element, and a polymorphic sub-document whose fields are mutually exclusive. Field names that are not ASCII are kept, and a collection holding one document per integration keeps all of its names. --- .../ide/db/introspect/MongoIntrospector.kt | 119 ++++++++- .../ide/db/introspect/MongoMapShapeTest.kt | 179 +++++++++++++ packages/mongodb/src/introspect.ts | 114 +++++++- packages/mongodb/test/map-shaped-keys.test.ts | 248 ++++++++++++++++++ 4 files changed, 643 insertions(+), 17 deletions(-) create mode 100644 packages/jetbrains/src/test/kotlin/com/rahulmahadik/asksql/ide/db/introspect/MongoMapShapeTest.kt create mode 100644 packages/mongodb/test/map-shaped-keys.test.ts diff --git a/packages/jetbrains/src/main/kotlin/com/rahulmahadik/asksql/ide/db/introspect/MongoIntrospector.kt b/packages/jetbrains/src/main/kotlin/com/rahulmahadik/asksql/ide/db/introspect/MongoIntrospector.kt index 1854084..659696e 100644 --- a/packages/jetbrains/src/main/kotlin/com/rahulmahadik/asksql/ide/db/introspect/MongoIntrospector.kt +++ b/packages/jetbrains/src/main/kotlin/com/rahulmahadik/asksql/ide/db/introspect/MongoIntrospector.kt @@ -84,10 +84,90 @@ object MongoIntrospector { fun inferColumns(samples: List): List { if (samples.isEmpty()) return emptyList() val stats = linkedMapOf() + val parentOf = linkedMapOf() for (doc in samples) { - walkDocument(doc, prefix = "", depth = 0, seenInThisDoc = mutableSetOf(), stats = stats) + walkDocument(doc, prefix = "", depth = 0, seenInThisDoc = mutableSetOf(), stats = stats, parentOf = parentOf) } - return stats.map { (path, s) -> s.toColumnInfo(path, samples.size) } + val mapShaped = mapShapedPaths(stats, samples.size, parentOf) + val dataKeys = mapShaped.values.flatten() + return stats + // A key of a map-shaped path is data, not a field: it must not become a column name. + .filterKeys { path -> dataKeys.none { path == it || path.startsWith("$it.") } } + .map { (path, s) -> s.toColumnInfo(path, samples.size, if (path == ROOT) null else mapShaped[path]?.size) } + } + + /** A child field is part of the record's shape once it recurs in this share of the parent's documents. */ + private const val STABLE_CHILD_RATIO = 0.6 + + /** A path segment that reads as a field name.

An integer column holding a moment carries no unit. Comparing epoch milliseconds against epoch seconds matches every row, and against a text date matches none. The unit is now read from the column's range and stated in the schema; a range spanning two units, or a sentinel such as a "never expires" maximum, yields no hint rather than a wrong one. A JSON column carries no key names, so the model invented one and matched nothing. The schema now names the accessor for the engine and how many keys recur. The key NAMES ride the existing cell-value opt-in: a map with a stable key set is structurally identical to a record, so no threshold separates them and the names are treated as data. Lists are described by their element type and the membership test that engine actually accepts. A filter comparing a column against a value the column does not hold is confirmed against the database and reported, instead of answering zero as though nothing matched. Only a literal that decides the result counts: under OR, NOT, CASE or a partial IN the query returns rows, and a caveat there would contradict the answer beside it. Identifiers, moments and measurements are left alone, views are never probed, and the values are named to the model only under the same opt-in. The judgement is shared: one module per language, with each engine supplying only its own probe SQL and accessor. Both are held to one set of golden vectors, so the two implementations cannot drift apart the way they already had. Probes are bounded per table and per query, carry a timeout on every engine, and never overwrite a comment the schema already had. --- packages/core/README.md | 14 +- packages/core/src/catalog.ts | 2 +- packages/core/src/column-hints.ts | 184 +++++++ packages/core/src/dialects.ts | 16 + packages/core/src/engine.ts | 83 ++- packages/core/src/index.ts | 13 + packages/core/src/semantics.ts | 133 +++++ packages/duckdb/src/browser.ts | 11 +- packages/duckdb/src/index.ts | 21 +- packages/duckdb/src/shared.ts | 89 ++++ packages/jetbrains/build.gradle.kts | 4 + .../asksql/ide/AskSqlEngineService.kt | 6 +- .../asksql/ide/db/introspect/ColumnHints.kt | 283 +++++++++++ .../ide/db/introspect/DuckDbIntrospector.kt | 10 +- .../asksql/ide/db/introspect/Introspector.kt | 9 +- .../asksql/ide/db/introspect/JsonKeys.kt | 119 +++++ .../ide/db/introspect/MySqlIntrospector.kt | 5 +- .../ide/db/introspect/OracleIntrospector.kt | 5 +- .../ide/db/introspect/PostgresIntrospector.kt | 5 +- .../ide/db/introspect/SqliteIntrospector.kt | 13 +- .../asksql/ide/engine/EnginePipeline.kt | 103 +++- .../asksql/ide/engine/Semantics.kt | 111 ++++ .../asksql/ide/db/HintParityTest.kt | 86 ++++ .../asksql/ide/db/SqliteValueHintTest.kt | 149 ++++++ .../asksql/ide/engine/CodedValueFloorTest.kt | 169 +++++++ .../jetbrains/tools/parity/vectors/hints.json | 472 ++++++++++++++++++ packages/mysql/src/introspect.ts | 87 +++- packages/oracle/src/introspect.ts | 121 ++++- packages/postgres/src/introspect.ts | 109 +++- packages/server/README.md | 2 +- packages/sqlite/src/index.ts | 97 ++-- packages/sqlite/test/epoch-unit-hint.test.ts | 20 + packages/sqlite/test/hint-parity.test.ts | 64 +++ packages/sqlite/test/json-key-hint.test.ts | 160 ++++++ tests/bundle-size.test.ts | 19 +- tests/coded-value-floor.test.ts | 223 +++++++++ tests/no-data-to-model.test.ts | 87 ++++ 37 files changed, 3031 insertions(+), 73 deletions(-) create mode 100644 packages/core/src/column-hints.ts create mode 100644 packages/jetbrains/src/main/kotlin/com/rahulmahadik/asksql/ide/db/introspect/ColumnHints.kt create mode 100644 packages/jetbrains/src/main/kotlin/com/rahulmahadik/asksql/ide/db/introspect/JsonKeys.kt create mode 100644 packages/jetbrains/src/test/kotlin/com/rahulmahadik/asksql/ide/db/HintParityTest.kt create mode 100644 packages/jetbrains/src/test/kotlin/com/rahulmahadik/asksql/ide/db/SqliteValueHintTest.kt create mode 100644 packages/jetbrains/src/test/kotlin/com/rahulmahadik/asksql/ide/engine/CodedValueFloorTest.kt create mode 100644 packages/jetbrains/tools/parity/vectors/hints.json create mode 100644 packages/sqlite/test/hint-parity.test.ts create mode 100644 packages/sqlite/test/json-key-hint.test.ts create mode 100644 tests/coded-value-floor.test.ts diff --git a/packages/core/README.md b/packages/core/README.md index fb5424f..4d7d5fe 100644 --- a/packages/core/README.md +++ b/packages/core/README.md @@ -24,7 +24,7 @@ import { PostgresConnector } from '@asksql/postgres'; const model = await resolveModel({ provider: 'groq', // openai | anthropic | google | azure | groq | nvidia | ollama | openai-compatible - model: 'llama-3.3-70b-versatile', + model: 'openai/gpt-oss-20b', // an example: use whatever your provider lists at /models apiKey: process.env.GROQ_API_KEY, }); @@ -113,10 +113,14 @@ Beyond ask -> approve -> run, all optional: - **Schema pruning + token budget** - large catalogs are pruned to the most relevant tables under a token budget (`config.pruner`) before prompting. - **Privacy by default** - only the schema is ever sent. `allowDataInPrompt` (default off) is the - opt-in for sampled cell values; with it off they are stripped at the single exit from the catalog, - so a connector that samples cannot leak them into any prompt - the first prompt, a repair, - `explain`, or `explainSchema`.

The notes now lead with a temporary provider key and a two-minute path that needs no database of the reviewer's own: save six lines as a CSV, add it as a connection, ask one question, and check the three numbers it returns. What to do without a key at all is stated too, since most of the UI is exercisable offline. They also named a model the provider has since retired, which answers 404. A reviewer following the instructions would have concluded the product does not work.
