Starlark packages serve custom JSON endpoints via +`api_routes` manifest key, with SSRF-safe outbound HTTP, LLM provider +access via BYOK chain, capability-based routing, and config-file +provider types. Five changesets (CS0–CS4). + +### New + +- **Extension API routes** (`/s/:slug/api/*path`) — Starlark packages + declare routes in `manifest.api_routes` and implement `on_request(req)` + entry point. Supports exact and prefix path matching, wildcard methods, + and boolean shorthand. JWT-authenticated. +- **HTTP outbound module** (`http`) — `http.get/post/put/delete/request` + builtins with SSRF protection (private/loopback IP blocking via + `net.Dialer.Control`), manifest-based allowlist/blocklist + (`network_access.allow/block`), redirect chain validation, 1 MB + response cap, 10 s timeout. Requires `api.http` permission. +- **Provider module** (`provider`) — `provider.complete(messages, model?, + max_tokens?, temperature?)` makes synchronous LLM calls via BYOK chain. + `requires_provider` manifest key with optional `provider_config_id` pin + and `model` default. Requires `provider.complete` permission. +- **`RunContext`** — per-invocation state (user_id, channel_id) passed + through `CallEntryPoint` for user-scoped modules. All callers updated: + API routes pass JWT user, task executor passes owner, filters pass nil. +- **`ProviderResolver` interface** — decouples sandbox from handlers + package (avoids circular dependency). `ProviderResolverAdapter` in + handlers bridges to `ResolveProviderConfig` + provider registry. +- **`capability_match` routing policy** — filters candidates by model + capabilities (`required_caps: ["tool_calling", "vision"]`) with + optional `prefer_cheapest` sort by output price. Forward-compatible + with unknown capability names. +- **Config-file provider types** — `PROVIDER_TYPES_FILE` env var points + to JSON array of custom provider type definitions. Registers + OpenAI-compatible endpoints (Ollama, LiteLLM, vLLM) at startup + without code deploy. Built-in IDs are protected from override. +- **`provider.complete` permission** — new extension permission constant + for LLM completion access from Starlark scripts. + +### Changed + +- `Runner.ExecPackage` and `Runner.CallEntryPoint` signatures gain + `*RunContext` parameter. All callers updated (breaking internal API, + no external impact). +- `Runner.buildModules` receives manifest for module-specific config + (http reads `network_access`, provider reads `requires_provider`). +- Routing policy admin handler validation switch includes + `capability_match`. +- `PolicyConfig` gains `RequiredCaps` and `PreferCheapest` fields. +- Routing `Context` gains `Capabilities` map for capability-match + evaluation. + +### Deferred + +- **Server-side tool execution in completion handler** → v0.29.2. + `provider.complete()` covers bare completions; full tool loop + (extensions defining tools that execute server-side during chat + completions) requires tool registry integration with the sandbox, + which aligns with the DB extensions scope. + ## [0.29.0] — 2026-03-17 ### Summary diff --git a/VERSION b/VERSION index ae6dd4e..25939d3 100644 --- a/VERSION +++ b/VERSION @@ -1 +1 @@ -0.29.0 +0.29.1 diff --git a/docs/ICD/enums.md b/docs/ICD/enums.md index c714755..1527e6c 100644 --- a/docs/ICD/enums.md +++ b/docs/ICD/enums.md @@ -254,6 +254,21 @@ Permissions are granted via groups.
