Ultracode

Dynamic workflows for DeepSeek Harness.

Ultracode is a session mode that turns every substantive task into a multi-agent workflow. Arm it once; the agent scopes the work, writes a workflow script, fans out subagents in phases, verifies adversarially, and synthesizes the result.

Features

• Session mode, not a model setting. /ultracode [on|off|status] arms one session. The stance is folded from the command log, so resume, fork, and replay restore it.
• Workflow-first policy. While armed, a prompt section after the workflow tool's own guidance classifies work as substantive or trivial, requires phases and pipeline/parallel fan-out, isolates writers, adds adversarial verification, and asks for evidence in the report.
• Composer switch. A quiet bordered pill when off; a flat accent tint and dot when armed, plus a thin seam along the composer edge. No gradients, no icon glyphs.
• Workflow sidebar. The ULTRA badge opens a right-sidebar ledger: running and finished runs, phase cards with progress rails and dots, per-agent status, model, tokens, and wall time, verification tags, a high-fan-out marker, and child-transcript drill-down.
• Answers from the log. No new session-event types. One projection folds /ultracode command lifecycles; another folds tool-workflow/* records and closes runs abandoned by interrupted or forked turns. Phases keep their raw identity; cancelled outcomes stay distinct from failures.
• No build step, no dependencies. Plain ESM and browser JavaScript, host theme tokens, English and Chinese copy.

Preset compatibility

Ultracode is a stance, not a preset. It needs the preset's workflow tool.

Preset	workflow tool	Ultracode behavior
Standard	yes	Full policy, phases, subagents, verification, and ledger.
Creator (cordis)	yes	Full; Standard's tools plus plugin-authoring tools.
PTC	no; only run_code and its SDK	Policy suppressed. The overview reports Workflow unavailable in this preset; no workflow runs. PTC can call subagents as SDK bindings, but that is code-level PTC, not a tracked Ultracode workflow.
Minimal	no; persistent shell + read_image	UI-only. The complete persona also suppresses the policy; the overview reports Workflow unavailable in this preset.
Custom	depends on its composition	Full when it composes workflow-ptc and tool-workflow; otherwise the policy is suppressed.

The policy checks whether workflow is model-visible for the agent. The overview warning recognizes the built-in minimal and ptc presets; a custom preset without workflow gets the suppressed policy but no preset-name warning.

Install

Requires DeepSeek Harness with the workflow tool and the Web/Desktop right sidebar. Tested with 0.2.1-rc.2; nearby versions with the same services should work.

From GitHub

1. Open Plugins in the DSH sidebar.

2. Choose Add plugin → Install third-party plugin.

3. Enter the repository URL:

   https://github.com/Big-Smarty/dsh-ultracode.git
   

   A local clone path works too, and keeps the checkout linked for edits.

4. Install and enable the bundle, then refresh the page once so the client half loads.

Or ask your DSH agent to install the bundle from the same URL.

Local clone

git clone https://github.com/Big-Smarty/dsh-ultracode.git
cd dsh-ultracode
npm test

Install the cloned directory through Plugins → Add plugin as above. The plugin is linked rather than copied, so later edits are picked up after a refresh.

Usage

Action	How
Arm the session	/ultracode, or click the Ultracode pill in the composer
Disarm	/ultracode off, the composer pill, or the panel overview's arm control
Check the stance	/ultracode status
Open the ledger	Click the ULTRA badge in the session header, or right sidebar → Ultracode
Inspect a run	Expand Finished, open a phase, click an agent to read its child transcript

Ultracode is per session. Trivial requests — a lookup, a one-line edit, a single command — stay direct and say why. Substantive requests become workflows.

The panel is workflow-focused. Shell and other background jobs remain in DSH's existing jobs control.

Troubleshooting

• The ULTRA badge shows a red ! — hover it for the failure. The opener falls back to expanding the right sidebar guide.
• The Ultracode tab is missing or unavailable after an update — hard-refresh the page (Ctrl+Shift+R). Client plugins are loaded from the page's module graph at boot, so a stale graph can survive a hot reload.
• The badge does nothing at all — check Settings → Plugins for a page-local client sync error, then refresh and retry.

How it works

• ultracode projection — { active, pending } folded from command/run / command/done.
• ultracodeRuns projection — run, phase, member, status, and timing data folded from tool-workflow/run-start|agent-start|agent-end|run-end, with turn/end handling for interrupted and forked turns.
• ultracode:policy — a prompt section at order 2650, after the workflow tool's guidance at 2600; empty while disarmed.
• Client half — a composer pill, an ULTRA badge, an armed seam, and a right-sidebar tab type. Agent model/token/time values join each member's childId to the sessions catalog.

Development

npm test

The tests use Node's built-in test runner and cover the stance, the workflow ledger, abandoned-run closure, phase identity, cancellation, and checkpoint sanitization. CI runs on every push and pull request.

index.js            Host half: projections, policy section, /ultracode command
client.js           Client half: switch, badge, seam, workflow sidebar, styles
cordis.patch.yml    Loads the bundle row
locale/             Plugin-inventory metadata (en, zh)
test/               Projection tests
docs/               Architecture and design notes

Cost and safety

Ultracode deliberately spends more tokens and time: it asks for several child agents per substantive task. /ultracode off returns to normal execution immediately.

The plugin runs Host code in-process with your permissions. Install it only if you trust the source. It does not bypass approvals, sandbox policy, plan mode, or tool restrictions.
