dsh-turn-fold

English | 简体中文

A dsh-harmony provider that adds Codex-Desktop-style turn folding to the DSH WebUI conversation.

During a turn, the summary bar remains visible while native thinking, notes, commands, and tool calls keep streaming. Consecutive reasoning and tool activity share one compact group from the second item onward. When a turn settles, known Agent activity, including context injection, moves into one disclosure immediately before the final answer. Its configurable metrics default to wall time, tool-call count, and input/output tokens, and appear only when the loaded turn contains enough data to calculate them without guessing.

The final answer is located through turn-tail.closing.finalNode, not finish_reason or DOM position. Completed, stopped, and interrupted turns fold, with distinct status labels for the latter two. A turn remains expanded when DSH marks its closing branch unavailable, when any later node follows the closing answer, or while the user has keyboard focus or an active text selection inside its activity. Failed, max-token, closing-less, and open turns also stay expanded so errors and unfinished work are never hidden.

Expanding reuses the original native node renderers, so tool details, copy, and file links keep working. Open turns are remembered per session and turn while the WebUI remains loaded. The disclosure has keyboard-visible focus, accessible state and action labels, responsive wrapping, reduced-motion handling, and a short open/close transition that unmounts the activity after it closes.

How it works

Two pinned Source Patches run in memory against the compiled browser bundle of @deepseek-ai/dsh-client-ui-conversation (lib/client.js); installed DSH files are never modified.

Patch	Selector (expect 1)	Effect
inject-turn-fold-runtime	FunctionDeclaration[name.name="ChatView"], VariableStatement:has(VariableDeclaration[name.name="ChatView"])	Injects the fold renderer + disclosure UI into either native or decorated ChatView
rewrite-node-render-loop	CallExpression[expression.name.name="map"][expression.expression.name="order"]	Replaces the order.map(...) node loop with the per-turn renderer

Install

dsh plugin --profile web add github:CH4ACKO3/dsh-turn-fold
dsh harmony status --profile web   # both patches must be `bound`

Test

node test/run.cjs

npm install installs test-only copies of the pinned DSH conversation package, TypeScript, and TSQuery. The test suite applies both patches in memory, parses the final browser bundle, and covers completed, split-activity, post-closing, partial-history, failed, interrupted, open, accessibility, and state-retention behavior. A missing target or selector mismatch fails the test; it is never reported as a skipped pass.
