* 🎯 fix: Infer Agents Endpoint for Model Specs Naming an Agent A model spec whose preset names an `agent_id` but omits `endpoint` was unusable. `isModelSpecEndpointMatch` compares the request's endpoint to `preset.endpoint` by strict equality, so an undefined endpoint matched nothing and every request selecting the spec was rejected with a bare `Model spec mismatch` — an error naming neither the spec nor the missing field. The selector had the matching half of the same gap: `handleSelectSpec` read `preset.endpoint` directly, so it sent no endpoint and skipped assigning `agent_id` to `model`. Fixing only the server would leave the request malformed, so the resolution is shared between both. - Add `resolveModelSpecEndpoint` to `librechat-data-provider`, inferring the agents endpoint when a preset names an agent and none is set. An explicit `endpoint` always wins, so configured specs are unaffected. - Use it for endpoint matching and in the selector, so the menu and the request pipeline resolve a spec identically. * 🔁 refactor: Materialize Inferred Spec Endpoints at Config Load The review showed the lazy-resolver approach was unsound end to end: config validation rejected an endpoint-less spec before the resolver could ever run (`tPresetSchema` requires the `endpoint` key), and the resolver was applied at 2 of ~8 read sites, leaving selection handlers, startup presets, access filters, and provider-key reachability reading the raw preset. Materialize once at the boundary instead: - `tModelSpecPresetSchema` now makes `endpoint` optional (`nullish`). This is barely a widening — `endpoint: null` already validated — and only for model-spec presets; `tPresetSchema` is untouched. - `materializeModelSpecEndpoints` writes each spec's resolved endpoint back onto its preset. `createAppConfigService` applies it at both effective-config assembly points — YAML base load and DB-override merge — so admin-panel specs stored in override documents are covered. Identity-preserving, so cached configs see no new references when nothing needs filling in. - Every consumer now reads complete specs; the client's lazy resolve in `handleSelectSpec` is reverted to a raw read. `getModelSpecPreset` and the two hand-rolled preset constructions resolve the endpoint explicitly, which the narrowed preset type now enforces at compile time for any `TPreset`-shaped destination. - `isModelSpecEndpointMatch` keeps the resolver as request-time defense. * 🩹 fix: Materialize Spec Endpoints Before the YAML Missing-Endpoint Guard `processModelSpecs` warns and skips any spec whose preset lacks an endpoint, and it runs inside `loadBaseConfig` — so the previous commit's materialization received a YAML list from which the inferable spec had already been dropped. Only DB-override specs (merged after the guard) actually benefited. - Materialize at the entry of `processModelSpecs`, so inference happens before the guard and YAML agent specs survive it. The guard keeps skipping genuinely endpoint-less specs. The `createAppConfigService` calls stay: the base-path one guards alternate `loadBaseConfig` implementations, the merged-path one covers override documents, and both are identity-preserving no-ops when specs are already complete. - Constrain the widened schema: omitting `endpoint` is only legal when the preset names an `agent_id`. A preset with neither validated as a hard error before the key became optional, and silently accepting it would trade that startup-time error for a dead spec. An explicit `endpoint: null` (valid before this PR) keeps validating. * 🩹 fix: Infer Only From Non-Empty Agent IDs, Never Over Explicit Null Two edge cases in the inference contract: - `agent_id: ''` (what a form-backed writer persists for an untouched field) passed the nullish checks, validating and materializing a spec that names no agent. Both the refinement and the resolver now require a non-empty id, so such config fails validation loudly instead of producing a selectable spec that cannot work. - `endpoint: null` alongside an `agent_id` was treated as inferable, silently activating a spec that validated — and was skipped — before this PR. An explicit null is a statement, not an omission: the resolver now infers only when the key is absent, preserving prior behavior for previously valid configs. |

🚀 What's New in v0.8.8-rc1
- Agent run control: Interrupt or steer an Agent mid-run, queue follow-up messages, and reclaim, edit, or escalate pending steers.
- Human-in-the-loop Agents: Agents stream question progress, ask up to four related questions in one form, pause for input or tool approval, and resume.
- Unified Agent Builder: A redesigned Tools marketplace brings together Skills, MCP, Code Interpreter, orchestration, Programmatic Tool Calling, model-spec controls, and per-tool background and intent settings.
- Readable Agent activity: Generated activity-group headers, parent phase summaries, and live tool intent labels make long reasoning and tool runs easier to scan.
- Code Interpreter workflows: Code and shell tools can run in the background, sandbox images return as viewable artifacts, and highly experimental stateful sessions can reuse prewarmed conversation workspaces.
- Agent extensibility: Experimental Agent Plugins can bundle deployment Skills, MCP servers, and opt-in command hooks, while explicit subagents initialize only when selected.
- Memory, context, and identity: Agents can manage memory with optional per-agent isolation, expose support contacts safely, and show a more faithful Context Usage gauge.
- Sharing and files: Shared conversations show a badge and update at a stable URL, while signed-in viewers can continue them as personal copies.
- Artifact workflows: Open previews fullscreen, work with PowerPoint
.potxtemplates across upload, search, and code execution, upload shell scripts across common MIME variants, export Mermaid diagrams as SVG or PNG, and download original Office files from the artifact panel. - Models and reasoning: Added GPT-5.6 with Responses API reasoning controls, Claude Opus 5 and Sonnet 5, Gemini 3.7 and 3.6 Flash, and Gemini 3.5 Flash-Lite.
- Langfuse observability: Configure encrypted Langfuse connections in-app, let authorized admins open sampled sessions directly, optionally fan out traces by tenant, and suppress central export per run.
- Administration and security: Delegate config sections, encrypt registered secrets, enforce SSRF checks for speech, OCR, and web tools, and generate unique temporary credentials when secrets are blank.
- Messages and navigation: Right-aligned user turns, unified multi-part editing, full-message copy, a dock-style message rail, virtualized search, smooth streaming, and faster Agent startup.
- Streaming and tool reliability: Adaptive provider smoothing, Redis delta batching, dynamic MCP tool refresh, parsed MCP response media types, runtime OAuth recovery, and Agent stream circuit breakers improve long-running workflows.
- Deployment and reliability: Added configurable HTTP timeouts, Amazon DocumentDB 5.0+ support, low-noise Redis and browser observability, and a rolling-upgrade-safe generation protocol.
