Garry TanandClaude Opus 4.7 6b8d50f7d9 feat(agents): v0.38 Slice 1 — kill the Anthropic pin, route through gateway.toolLoop
Closes the three-layer Anthropic-only enforcement (queue gate / model-config
runtime fallback / doctor check) with a capability-based gate driven by the
recipe registry. Any provider that supports native tool calling can now
run the subagent loop.

Three layers reworked:

  - queue.ts:87-106 (S1.7) — drop isAnthropicProvider hard-reject. Replace
    with classifyCapabilities() check: refuse only when verdict is
    'unusable:no_tools' or 'unknown'. Degraded providers (no caching, no
    parallel tools) pass through; the gateway prints once-per-(source, model)
    cost warnings at first dispatch.
  - model-config.ts:205 (S1.8) — rename enforceSubagentAnthropic →
    enforceSubagentCapable. Keeps the once-per-(source, model) warn seam
    from v0.31.12 and inherits the same suppression Set so doctor + first-
    call surfaces stay in sync. Legacy name kept as a thin wrapper for
    external callers.
  - doctor.ts:1189 (S1.9) — rename subagent_provider check →
    subagent_capability. The check now surfaces three states: 'unusable',
    'unknown', and 'degraded:no_caching' (the cost-regression warn). Paste-
    ready fix hints point at `gbrain config set models.tier.subagent`.

Subagent handler routing (S1.5 + S1.10):

  - New `agent.use_gateway_loop` config flag (default off). When enabled,
    the handler routes through gateway.toolLoop() — provider-agnostic via
    the Vercel AI SDK. When disabled, the legacy Anthropic-direct path
    stays unchanged.
  - Handler-entry capability check refuses tool-unsupported / unknown
    providers loudly. With flag OFF + non-Anthropic model, refuses with a
    paste-ready hint.
  - runSubagentViaGateway() (new helper) bridges the existing ToolDef
    registry to gateway's ChatToolDef + ToolHandler shapes. Persists to
    the v0.38 stable-ID columns (ordinal + gbrain_tool_use_id) at first
    observation; settles complete/failed on tool exit.
  - D5 read-time shim (S1.6) — loadPriorToolsV2 + adaptContentBlocksToChatBlocks
    handle v1 Anthropic-shaped legacy rows alongside v2 gateway-shaped writes
    so crash-replay reconciles across the upgrade boundary.

Tests:

  - test/agent-cli.test.ts Layer 1/2/3 cases flipped from "rejects non-
    Anthropic" to "any tool-supporting provider accepted; refuses unknown
    and embedding-only providers". 4 new cases covering openai, google,
    unknown provider, embedding-only.
  - All 27 cases pass; typecheck clean.
