From d03ba0df6afdebdabe7b6366b9a57fdd0932872e Mon Sep 17 00:00:00 2001 From: Michiel De Smet Date: Sat, 21 Mar 2026 09:32:02 -0700 Subject: [PATCH 1/9] feat: add Snowflake Cortex as an AI provider Adds `snowflake-cortex` as a built-in provider using Programmatic Access Token (PAT) auth. Users authenticate by entering `::` once; billing flows through Snowflake credits. Includes Claude, Llama, Mistral, and DeepSeek models with Cortex-specific request transforms (max_completion_tokens, tool stripping for unsupported models, synthetic SSE stop to break the AI SDK's continuation-check loop when Snowflake rejects trailing assistant messages).

2026 10:54:03 -0700 Subject: [PATCH 2/9] fix: harden Snowflake Cortex provider with `altimate_change` markers and edge case fixes MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add `altimate_change` markers to all upstream-shared files (`provider.ts`, `schema.ts`, `plugin/index.ts`) to prevent overwrites on upstream merges - Validate account ID against `^[a-zA-Z0-9._-]+$` to prevent URL injection - Remove `(auth as any).accountId` casts — use proper type narrowing - Fix `env` array: `SNOWFLAKE_PAT` → `SNOWFLAKE_ACCOUNT` (matches actual usage) - Fix `claude-3-5-sonnet` output limit: `8096` → `8192` - Strip orphaned `tool_calls` and `tool` role messages for no-toolcall models - Use explicit `Array.isArray(tool_calls)` check for synthetic stop condition - Remove zero-usage block from synthetic SSE to avoid broken token accounting - Handle `ArrayBuffer` body type in fetch wrapper - Reduce PAT expiry from 365 → 90 days (matches Snowflake default TTL) - Add 14 new test cases covering URL injection, orphaned tool_calls, empty tool_calls array, SSE format validation, missing messages, and env/output limits Co-Authored-By:

Content-Transfer-Encoding: 8bit Addresses CodeRabbit review comments: - Require `auth.type === "oauth"` before autoloading — env-only `SNOWFLAKE_ACCOUNT` no longer makes the provider look configured without a PAT - Set `env: []` so `state()` env-key scan doesn't treat account name as an API key - Validate account from env fallback against `^[a-zA-Z0-9._-]+$` - Add test: env-only without oauth does NOT load the provider - All provider tests now set up/teardown oauth auth properly via save/restore - Update env array assertion: `toContain("SNOWFLAKE_ACCOUNT")` → `toEqual([])` Co-Authored-By:

returning SSE format for non-streaming requests (Major, flagged by GPT 5.2 Codex) - Delete `content-length` header after body mutation to prevent length mismatch (Minor, flagged by GPT 5.2/Kimi/Gemini consensus) - Export `VALID_ACCOUNT_RE` from `snowflake.ts` and import in `provider.ts` to eliminate duplicated regex (Minor, flagged by GLM-5) - Add `claude-3-5-sonnet` to toolcall capability test (Kimi K2.5) - Add 3 new tests: `stream: false` skips synthetic stop, `stream: true` triggers it, absent `stream` field defaults to streaming behavior Co-Authored-By: Claude Opus 4.6 (1M context) ---

Key findings and fixes: Model list changes (from real API probing): - Replace `llama3.3-70b` (unavailable) with `snowflake-llama-3.3-70b` - Add `llama3.1-70b`, `llama3.1-405b`, `llama3.1-8b`, `mistral-7b` -
