dsh-any-attachment

A DeepSeek Harness (dsh) plugin bundle that lets the Web UI attach files of any type as pathless @-mentions: type @ to pick a workspace file, or drop a file (or use the + button) to tag it into your message — the agent then reads the file itself with its own tools. Mentions carry the name only, never a path. Raster images keep flowing through the built-in image pipeline. No changes to the harness repo, and nothing is written into your workspaces.

How mentions work

• @-list: in the composer, type @ and a menu shows the session workspace's files, recursively and flat (src/main.ts, docs/guide.md, …). Type more to filter; pick one and a pathless @name chip is inserted into the draft.
• Drop / + button: drop a local file onto the composer (or click +) and it is stored privately; the draft gains an @<stored-name> chip — no path, no drive letter.
• Send as usual (Enter or the send button) — every mention chip resolves to its exact file location in the sent message (@name (C:\...\absolute\path)), so the agent reads the file directly instead of guessing where it lives.
• Raster images (png/jpeg/webp/gif) still route to the built-in image pipeline (vision models see them).
• Files live under $DSH_HOME/attachments-any/ — private, never dumped into a workspace.

How it works

• Host (lib/): registers an RPC channel /attachments-any (authority trusted-host, same LAN fence as /api). list { sessionId } walks the session workspace recursively and returns relative paths; upload validates base64/size/name, writes into the private store, and returns the stored name (deduped with -2 suffixes). A system-prompt section tells the agent that a referenced @name lives at ./<name> relative to its working directory, or in the private store otherwise.
• Client (client/): composer + button (conversation.input.left), a capture-phase drop handler, and an @file input-trigger source (workspace autocomplete, pathless picks). Rasters route through createDraftImages/addImages; everything else uploads via the channel and the mention @<name> is appended to the composer draft via inputActions.setDraft.

The agent reads the file at the resolved path with its own tools — no extraction, no download UI, no special send flow.
