Oversized MCP and Composio tool results can now be recovered in full. Core caches the oversized output in a per-session in-memory cache and sends the model a bounded preview plus a `cline://cache/...` URI that `read_files` can page through by line range. Custom tools can opt in with `resultPolicy: "cache-oversized"` on `createTool`. Entries expire after five model iterations without a read, the cache is capped at 16 MiB per session, and original output stays in history and tool events Custom providers from `providers.json`/`models.json` now run on the agent path. They appeared in pickers but failed with `Unknown or disabled provider ""`, because `createAgentModelFromConfig` only registered builtin providers with the gateway.

`@cline/llms` now exports `resolveGatewayProviderRegistration(Sync)` Provider settings saves are more robust. Settings still save when model discovery fails, mutations are serialized, a failed catalog write restores the previous settings, and persistence errors propagate to the caller (`saveLocalProviderSettings` is now async). Model source requests are authenticated, and source catalogs refresh when credentials or endpoints change Refreshed the model…
