feat: add Snowflake Cortex as an AI provider#349

Conversation
Adds `snowflake-cortex` as a built-in provider using Programmatic Access Token (PAT) auth. Users authenticate by entering `<account>::<token>` 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).

Don't expose SNOWFLAKE_ACCOUNT as a provider credential.
provider.env is consumed as auth input in state() (Lines 1053-1058), and getSDK() later copies a single env value into apiKey on Line 1248. With the current loader + metadata, SNOWFLAKE_ACCOUNT=myorg makes the provider look configured even when no PAT exists, so requests go out as Authorization: Bearer myorg and never get the Snowflake PAT header from packages/opencode/src/altimate/plugin/snowflake.ts Lines 91-139. The env fallback also bypasses the account validation in packages/opencode/src/altimate/plugin/snowflake.ts Lines 10-17, so malformed values are interpolated straight into baseURL.

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([])`

autoload: false here does not actually disable an invalid Snowflake provider.
The Snowflake auth plugin added in this PR can already merge snowflake-cortex into providers before CUSTOM_LOADERS runs, so this branch still leaves the provider registered when accountId is missing or fails the regex. Because makeSnowflakeModel() leaves api.url empty, that surviving provider has no Cortex base URL to fall back to. Please gate the plugin-auth merge on a valid account, or explicitly drop the provider when this validation fails.

Restore SNOWFLAKE_ACCOUNT after each test.
Env.remove and Env.set mutate shared Env state here, but the finally blocks only restore auth. That leaks Snowflake config into later tests and makes provider loading order-dependent.

The test setup mutates shared Env (calling Env.remove/Env.set) but only restores
auth in the finally blocks, leaking SNOWFLAKE_ACCOUNT across tests; update the
test init/cleanup logic (the init async functions and their corresponding
finally/teardown blocks around the provider loading in
packages/opencode/test/provider/snowflake.test.ts) to capture the original
Env.get("SNOWFLAKE_ACCOUNT") before mutating and restore it in the finally/after
step (analogous to how auth is restored), and do the same for the other affected
blocks referenced around lines 333-334 so each test restores SNOWFLAKE_ACCOUNT
to avoid test order dependency.
Fixes from 6-model consensus review (Claude, GPT 5.2, Gemini 3.1, Kimi K2.5, MiniMax M2.5, GLM-5): - Gate synthetic SSE stop on `stream !== false` to avoid 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) <noreply@anthropic.com>

🛠️ Refactor suggestion | 🟠 Major
Route at least one smoke path through the real provider contract.
This helper splits account/pat, sets the auth headers itself, and already sends max_completion_tokens, so the live calls never exercise the provider’s actual <account>::<token> parsing or request-transform chain. For an E2E suite of the new provider, at least the happy-path and streaming smoke tests should go through the same entry point/config shape production uses.

Avoid asserting the live PAT value directly.
If this fails, the assertion diff can expose SNOWFLAKE_CORTEX_PAT in CI logs. Keep exact token round-trip checks in unit tests with fake credentials and only assert non-sensitive properties here.

Verified against Snowflake account ejjkbko-fub20041 with cross-region inference enabled. 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` - All 10 models verified against live Cortex endpoint Tool calling fix: - Switch from blocklist (`NO_TOOLCALL_MODELS`) to allowlist (`TOOLCALL_MODELS`) — only Claude models support tool calls on Cortex, all others reject with "tool calling is not supported" E2E test improvements (24 tests, all pass against live API): - Test all 10 registered models for availability and response shape - Tool call support test: Claude accepts, non-Claude rejects - DeepSeek R1 reasoning format test (`<think>` tags in content) - Support key-pair JWT auth (no PAT required) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
From official Snowflake documentation (docs.snowflake.com): New models added (19 → 28 total): - OpenAI: `openai-gpt-4.1`, `openai-gpt-5`, `openai-gpt-5-mini`, `openai-gpt-5-nano`, `openai-gpt-5-chat`, `openai-gpt-oss-120b` - Claude: `claude-opus-4-6`, `claude-sonnet-4-5`, `claude-opus-4-5`, `claude-4-sonnet`, `claude-4-opus`, `claude-3-7-sonnet` - Meta: `llama4-maverick`, `mistral-large` Tool calling update: - Per docs: "Tool calling is supported for OpenAI and Claude models only" - Updated `TOOLCALL_MODELS` allowlist to include all OpenAI + Claude IDs Note: OpenAI models were not available on this test account (returned "unknown model") but are documented in the Cortex REST API reference.

snowflake-cortexas a built-in provider using Programmatic Access Token (PAT) auth. Users authenticate by entering<account>::<token>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).Co-Authored-By: Claude Sonnet 4.6 noreply@anthropic.com
