@deepseek-ai/dsh-client-ui-reference

English | 中文

Unified Web @file and @session source. The browser starts reference.files and reference.sessions Host RPCs together for an unquoted token, keeps the TUI's file-before-session ordering and labels, renders the rows under the non-selectable 文件与文件夹 and Session 对话 headings, and degrades either failed candidate domain independently. An open @"… token searches files only.

File picks insert the natural @path text used by the TUI. A file closes completion and adds a trailing space; a directory keeps the menu active at its trailing slash so the user can descend another level. Paths containing whitespace use @"path with spaces", and a quote the user opened explicitly remains quoted.

Session picks insert an atomic composer chip whose hidden ref and clipboard representation are the canonical @[label](dsh-session:…) mention returned by the Host. The visible chip uses @label; serialization never reconstructs identity from that label. Ordinary send delegates the canonical mention to session.prompt, where Host-side session-reference preparation owns validation, snapshotting, and model context.

The /client export is the plugin body (apply/inject) only; candidate encoding stays internal to the registration effect.

Model Experience

Indirectly, through @deepseek-ai/dsh-file-reference-local for path guidance and @deepseek-ai/dsh-session-reference for prepared session snapshots.

KV Cache effect

Candidate browsing has no model effect. A selected file or session changes only the new user-message suffix and any Host-prepared session-reference prefix attached to that message; earlier target history remains unchanged.

Known Limitations and Deferred Work

• Candidate failure is intentionally quiet — one unavailable or failed reference RPC yields no rows for that domain, while prompt submission still reports session-reference preparation failures through the ordinary send path.
• No browser-side file scan — Web completion requires a mounted Host ctx.fileReferences provider; the browser cannot fall back to its own filesystem.
• Session search remains metadata-only — discovery filters session id and cwd through ctx.sessionReferences; title and transcript full-text search are not available.
