DeepSeek Harness workspace tools: configure per-workspace Agent and permission presets that new root sessions apply automatically, so you stop re-selecting them on every new session.

Official extension points only — works out of the box on official DSH 0.1.5-rc.1 and later, with no DSH patches.

Features

• Adds a Settings → Workspace defaults page: each rule = pick a registered workspace + pick the new-session Agent preset and permission preset (both optional = inherit the global defaults).
• The workspace dropdown lists the workspaces registered in the sidebar in real time and shows workspace names only; rules pointing at a removed workspace are marked instead of failing silently.
• Rules are stored keyed by workspace id (with the path and title kept for display), so workspace renames and path-casing changes never break matching.

How it works

• Whenever a new root session is published (the official agent/created event, before the first turn), the plugin resolves the session's working directory (session.header.cwd) to a registered workspace; on a rule hit:
  • the Agent preset is switched through the official agentPresets.select and recorded durably on the session;
  • the permission preset is committed through the official permissionPresets.set (sandbox mode and approval policy follow).
• Match scope: the session cwd equals the workspace directory or sits inside its subdirectories.

Scope and precedence

• Only root sessions created afterwards are affected: existing, resumed, forked, and subagent sessions stay untouched (children are identified by the session header's parent-session marker and delegation depth).
• Once a session starts (first turn begins), it is never switched; started or resumed sessions matching a rule are left alone.
• A choice you make after the session arrives (the New Session chip's staged preset, an in-session switch) happens after the automatic application and always wins.
• A fresh session briefly shows the global default before the first turn, then switches to the workspace default — the session list and the durable log both record the switch.

Install and usage

dsh plugin --profile web add @ahiosuz/dsh-workspace-tools

1. Restart (or reload) DSH Web.
2. Open Settings → Workspace defaults → Add rule.
3. Pick a workspace from the dropdown (names only; hover for the full path), choose both presets, Save.
4. Create a new conversation in that workspace to verify: the rule presets apply automatically before the first turn.

Compatibility

• DSH 0.1.5-rc.1 (official build, no patches). Official capabilities used: the agent/created event, agentPresets.select, the permissionPresets service, a settings.installSection namespace, and the remote.workspace.follow state stream.
• Versions ≤0.3.0 relied on patch-provided extension points (the workspaceActions row menu and the sidebar.workspaces.overlay slot). The official repository does not accept external patches, so 0.4.0 moved to pure official extension points; configuration moved from the workspace row menu to the settings panel.

FAQ

Why does a new session briefly show the global default? The automatic application happens after the session is published (agent/created) and before the first turn — so the global default shows for a moment before the switch. That is the timing of the official create-then-switch flow; the final state is the workspace default.

Why did existing / resumed sessions not change? Rules only apply to newly created root sessions. Resumed, forked, subagent, and already-started sessions are explicitly skipped, and a session you chose manually stays on your choice.

My directory is missing from the workspace dropdown. The dropdown lists workspaces registered in the DSH sidebar. Register the directory as a workspace first, then add the rule on this page.

The switch failed — how do I debug it? The most common failure is the target preset itself failing to mount — for example a custom preset file whose persona entry lacks the required prefix field (the schema is prefix required plus optional suffix; writing text instead fails the mount). Mount failures are logged in the DSH server log; fix the preset file and newly created sessions pick it up.

Development

npm install
npm run check

npm run check builds both halves and runs smoke tests (rule matching, listener behavior, client bundle contract, dotted-inject regression guard). The npm package prebuilds and ships lib/index.js and lib/client.js; no lifecycle scripts run on install.

Security

The plugin only reads the session's working directory (session.header.cwd) and calls the official preset services. Rules live in your settings document (the workspace-tools namespace of settings.yaml) and can be edited or cleared at any time. The plugin contains no telemetry, no credential access, no command execution, and no network access. Enabling danger-full-access follows DSH's official permission-preset semantics; use it only for directories you trust.
