dsh-focus-chat

English | 中文

A plugin for the dsh web GUI that adds a focus chat tab — a condensed, Claude Code–style way to read a conversation.

Screenshots

Off — the normal chat view	On — the focus chat view

Instead of watching every step live, one assistant turn collapses into a single summary line:

Thought for 36s, loaded 3 context items, ran 2 shell commands, edited 8 files, read 17 files, listed 18 directories

…and the whole turn can fold into one Worked for Xm Ys line. Click any line to expand the full detail — tool cards, thinking, context injections, produced files, copy/fork actions — all drawn the same way as the normal chat rows. Your mid-turn interjections split the fold into per-stretch lines, each carrying its own duration, and a stopped turn reads Stopped after X instead of "worked". A background-task settlement — a tool-jobs notice injection like bash pnpm install [status: completed] — classifies into the summary line's N background jobs segment instead of riding it as a verbatim injected … account; expanding the line still shows the full notice body. File operations (edits / reads) never carry a failure tally on the summary line — edited N files reads the outcome — only command execution and other tools annotate failures.

Switch to it whenever you want the "what happened?" view, and flip back for the full transcript.

Install

# Install from npm (requires dsh >= 0.1.0-rc.6)
dsh plugin --profile web add @dingyi222666/dsh-focus-chat
# Restart dsh web; the tab mounts automatically
dsh web

Then open the Focus chat tab in any conversation.

Notes:

• dsh plugin behaves like adding a dependency to your web profile. A bundle plugin is loaded once its full package name appears in the profile's dsh.profile.bundles list (adds automatically on recent dsh builds; add it manually if your build does not); the bundle patch applies on the next boot.
• With the repo source-launched CLI, run the args through the bin directly (node --import tsx/esm apps/cli/src/bin.ts ...).

Why a separate tab, and not a patch into the chat view?

Short answer: the chat view's internals aren't open to third-party plugins — by design — and this plugin deliberately never touches dsh's own source. Concretely:

• Keyed slots are owned, not shared. The chat's rows render through slots like conversation.chat.node, tool.call.toolview, and conversation.chat.turnTail. Those slots are declared by the chat entries themselves, and the slot system rejects a second declaration at load time — the conflict is the design speaking. A plugin cannot insert its own rows into the chat transcript, and cannot even declare the chat's own slots.
• Plugins can't reuse the chat's renderer code. Importing values from another plugin package across the bundle boundary is forbidden (the bundle purity gate), so there's no way to borrow the chat's components — every row has to be drawn from the shared primitives and the public snapshot.
• The only legal insertion point is the conversation.view list slot — the whole message surface. That's why the plugin ships its own complete view instead of changing how the chat view displays.

If you want the chat view itself to behave differently, that's an in-repo change to the chat package — exactly what this plugin avoids.

What's missing

Focus chat is a faithful reading surface, not a second chat view:

• No Inspect / details-panel deep links. The chat's Inspect affordance needs internals plugins can't touch. The tool cards render the same content, just without the jump-to-details button.
• Third-party tool-card extensions don't render here. Cards that other plugins add to the chat view won't appear in the focus view; the built-in card renderers are used instead.
• Folding is per consecutive tool-run. Any visible content between two runs (a reply, a command, your interjection) keeps them separate.
• Inline file links need the optional file-mentions service — the same off switch the chat view uses.

Development

• yarn run build — builds the browser bundle and the Node half.
• src/client/focus-model.ts — the pure logic (folding, merging, row models); src/client/FocusView.tsx — the view.
• yarn test — behavior tests; yarn run typecheck — type gate.
• A --dev dsh web server hot-reloads rebuilt bundles — yarn run build alone is usually enough to see changes.

Model Experience

None. The view is a pure client derivation over the already-logged conversation snapshot; nothing here reaches a model request.

KV Cache effect

None; this package neither assembles nor sends provider requests.
