dsh-session-nav

English | 中文

A DeepSeek Harness Web plugin that adds a Codex-style session navigator on the left of the conversation.

It is an overlay only. It does not replace Chat, the sidebar, or the Trajectory tab.

What you get

• Idle: a packed stack of short dashes on the left edge of the conversation column — one dash per user, steering, or slash-command turn.
• Hover: neighbouring dashes lengthen in a delayed wave, then a prompt bubble, an optional Worked for duration, and an optional Edited N files +X −Y card.
• Jump: click a dash (or use ↑ / ↓ on the rail) to scroll that turn into view.
• Full log: older turns are listed from session.history even if Chat has not loaded them yet. Clicking one pages loadOlder until the row exists, then scrolls to it.
• Toggle: a tick-mark button in the session header. Preference is stored as dsh-session-nav:enabled in localStorage.

The rail sits vertically centered, capped at 66% of the conversation column, and scrolls inside itself when the stack is long.

Install

Wait until DSH is idle. Adding a plugin rebuilds the web profile and will interrupt a running task.

dsh plugin --profile web add github:karmiy/dsh-session-nav

Git-hosted plugins build on install. pnpm ≥10 blocks that prepare script until you allow it, so the first add fails with an allowBuilds hint. Copy the exact key into ~/.dsh/profiles/web/pnpm-workspace.yaml:

allowBuilds:
  dsh-session-nav: true

Then run the same add again and restart the web profile.

Pin a commit if you do not want a later push to change what runs:

dsh plugin --profile web add github:karmiy/dsh-session-nav#v0.1.0

Local checkout (after pnpm install):

dsh plugin --profile web add link:/absolute/path/to/dsh-session-nav

How it maps to the session

Development

Requires Node ^22.19 || >=24. Keep a DeepSeek Harness checkout as a sibling if you want pnpm typecheck / pnpm build (they resolve host types through ../deepseek-harness). Unit tests and prepare do not need it.

../deepseek-harness
../dsh-session-nav

pnpm install
pnpm test
pnpm typecheck
pnpm build

prepare runs tsdown only — no typecheck — so dsh plugin add github:… can build on a machine that does not have the harness source.

Do not dsh plugin add against a profile that is currently running a task.
