New Features

DeepSeek Harness on Cordis 0.1.7-rc.2

The bundled DeepSeek Harness (DSH) template has been upgraded to upstream 0.1.7-rc.2:

• PiAi multi-route configuration. New PiAiRoute support lets cordis.yml declare multiple provider routes; buildCommand now configures the primary and role-specific routes dynamically based on the connector type.
• Reasoning support. PiAi models can carry reasoning levels and token budgets.
• Built-in Office skills. The Cordis template now wires up a skill system — a skill registry (@deepseek-ai/dsh-skill), a skill tool (@deepseek-ai/dsh-tool-skill), and the Office skill (@deepseek-ai/dsh-skill-office). The harness can work with Word, Excel, and PowerPoint documents out of the box; the Office skill resolves its bundled assets from assetRoot, driven by DSH_OFFICE_ASSET_ROOT.
• API key config migration. apiKeyEnv moved from dsh-llm-deepseek (now a pure protocol layer) to dsh-llm-deepseek-api-key.

Inline file diffs in agent output

Added a FilePatch type and wired it through ExecuteProps, so execution messages can carry inline diffs. The parser extracts file patches from tool results and surfaces file modifications directly.

Board creation: skip the default column

CreateReq now accepts SkipDefaultColumn. When it is set, the automatic "To Do" column is not created, giving callers full control over board setup.

Faster recent-message retrieval

Added GetRecentMessages to the store interface and implemented it for the Mongo and Redis stores, so recent chat history can be read efficiently. agent/task/watch.go and the Xun store were updated to match.

OpenAPI: tai resource scopes

Added tai resource aliases — tai:all, tai:all:own, tai:all:team — across client and user roles, plus scopes for tai/proxy and tai/vnc, for finer-grained access control.

CUI (Chat UI Framework)

CUI is the Chat UI framework for building AI-native applications on Yao App Engine. It ships bundled with yao and is released alongside it (CUI has no separate version number). Recent CUI work:

Chatbox

• Per-tab model selection. Model state was lifted out of the input area into the Chatbox and a new ModelSelector component was added; each tab tracks its own connector, and model groups are fetched from the API.
• Draft and input caching. Editor state, including attachments, is cached and restored when switching chat tabs, with debounced draft saves.
• Cancellation handling. A new Cancelled message type; the stream handler now distinguishes cancellation from errors, and AIMessage renders it accordingly.
• Input gating. The input area is disabled while the workspace is offline or loading, or while recording.
• Video links. Video links now show a platform logo (Bilibili / YouTube) with refreshed styling.

Inbox

• Tasks from messages. Create a task directly from the message list, with workspace selection; new users get an initial task during onboarding.
• Task mail retrieval. New getTaskMails(chatId) API; MailTimeline loads a task's mail through it.
• Collapsible sidebar. The sidebar can collapse, with a category dropdown and unread counts.
• Loading polish. Message-loading exhaustion tracking and silent-mode refreshes avoid redundant fetches and loading flicker.

Kanban

• Task detail. Resource actions are disabled when a task's workspace is unavailable, and the task cache and workspace selection are cleared when switching tasks.

Models and UI

• Added the decision capability to the model selector (structured decisions).
• Card tooltips and text-overflow handling; workspace scrollbars with dark-mode support; a new "subtle" variant for Agent
