This PR now ships only what's needed to measure whether pre-execution SQL validation is worth it: - Keep: sql_pre_validation telemetry event + preValidateSql function - Change: pre-validation runs fire-and-forget (shadow mode) — emits telemetry with outcome=skipped|passed|blocked|error but never blocks sql_execute. Zero user-facing latency impact. - Revert: read.ts, apply_patch.ts, warehouse-test.ts, altimate-core-validate.ts, anthropic.txt system prompt changes — to be re-evaluated as separate PRs once real telemetry data validates need. After 2 weeks of shadow telemetry, we can decide whether the blocking behavior is worth the latency and false-positive risk. --- .../altimate/tools/altimate-core-validate.ts | 51 +------------------ .../src/altimate/tools/sql-execute.ts | 15 +++--- .../src/altimate/tools/warehouse-test.ts | 39 +------------- .../opencode/src/session/prompt/anthropic.txt | 20 +------- packages/opencode/src/tool/apply_patch.ts | 19 +------ packages/opencode/src/tool/read.ts | 16 ------ 6 files changed, 11 insertions(+), 149 deletions(-) diff --git a/packages/opencode/src/altimate/tools/altimate-core-validate.ts b/packages/opencode/src/altimate/tools/altimate-core-validate.ts index 921fdd2194..384b5faed0 100644 --- a/packages/opencode/src/altimate/tools/altimate-core-validate.ts +++ b/packages/opencode/src/altimate/tools/altimate-core-validate.ts @@ -2,9 +2,6 @@ import z from "zod" import { Tool } from "../../tool/tool" import { Dispatcher } from "../native" import type { Telemetry } from "../telemetry" -// altimate_change start — auto-pull schema from cache when not provided -import { getCache } from "../native/schema/cache" -// altimate_change end export const AltimateCoreValidateTool = Tool.define("altimate_core_validate", { description: @@ -15,20 +12,11 @@ export const AltimateCoreValidateTool = Tool.define("altimate_core_validate", { schema_context: z.record(z.string(), z.any()).optional().describe("Inline schema definition"), }), async execute(args, ctx) { - let hasSchema = !!(args.schema_path || (args.schema_context && Object.keys(args.schema_context).length > 0)) - // altimate_change start — auto-pull schema from cache when not provided - if (!hasSchema) { - const cachedSchema = await tryGetSchemaFromCache() - if (cachedSchema) { - args = { ...args, schema_context: cachedSchema } - hasSchema = true - } - } - // altimate_change end + const hasSchema = !!(args.schema_path || (args.schema_context && Object.keys(args.schema_context).length > 0)) const noSchema = !hasSchema if (noSchema) { const error = - "No schema provided.
