description: "Web @file and @session reference source for the composer: candidates, ordering, and atomic inline references (unified file/session picking)."

kind: "package-reference"

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

English | 中文

Summary

dsh-client-ui-reference is the unified Web @file and @session reference source: it registers the reference entry in the composer's inline-suggestion machinery so a user typing @ sees file and session candidates in one list. Files order before sessions, sections are labelled with locale-registered terms, and either candidate domain can fail independently without blocking the other. A pick inserts an atomic inline reference — a file closes completion with an editable path text, a session inserts a canonical mention — so the sent text is the same natural text the shared grammar defines. Selecting a session routes through the session-reference service, which validates the mention and captures model context at the pre-step boundary; this package itself registers no prompt or tool.

Table of Contents

Use this package

The source is active whenever the composition mounts this package and a Host ctx.fileReferences provider is available. Type @ followed by an unquoted token to see files first, then sessions; open @"… to search files only. The candidate list is a completion menu, not a search result page: pick once and keep typing.

What a pick inserts

A file closes completion as an atomic inline reference displayed with a file glyph and business-color filename. A directory remains plain editable path text with a folder glyph and keeps the menu active at its trailing slash, so you can descend another level. Paths containing whitespace use @"path with spaces", and a quote the user opened explicitly remains quoted.

A session pick inserts an atomic inline reference whose hidden ref and clipboard representation is the canonical @[label](dsh-session:…) mention returned by the Host; its visible form is a chat-bubble glyph plus the session title. Sending carries the mention through session.prompt, and the session-reference service validates it and captures model context at agent/pre-step.

Failure behavior

One unavailable or failed candidate domain yields no rows for that domain while the other still lists. A session-reference preparation failure occurs after prompt acceptance and terminates that agent turn.

Understand the implementation

Implementation internals — click to expand The source keeps candidate encoding internal to the registration effect: the `/client` export is the plugin body (`apply`/`inject`) only. ### Candidate flow For an unquoted token, the browser starts the `fileReferences/list` and `sessionReferenceResolver/candidates` Remote calls together, then deterministically orders files before sessions with locale-registered folder/file/session labels. Rows render under non-selectable file and session section headings without a redundant raw `reference` source title. ### Serialization File picks preserve the natural text defined by the shared `@path` grammar as the hidden serialized and clipboard form. Session picks use the canonical `@[label](dsh-session:…)` mention; serialization never reconstructs identity from the visible title.

Further Exploration

These pages cover the suggestion machinery, the reference seams, and the input pipeline.

Model Experience

Indirectly, through Host-owned providers, which own the file guidance and session snapshot preparation this package's reference selection delegates to them.

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 context that follows that message; earlier target history remains unchanged.

Known Limitations and Deferred Work

These limits define when the reference source cannot help; they are current package constraints.

  • Candidate failure is intentionally quiet — one unavailable or failed Remote discovery call yields no rows for that domain. A session-reference preparation failure occurs after prompt acceptance and terminates that agent turn.
  • 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, cwd, and the latest log-backed title through ctx.sessionReferenceResolver; message bodies and full transcripts are not searched.
