# @deepseek-ai/dsh-tui-demo
The full-screen terminal app: a Cordis plugin that composes [`@deepseek-ai/dsh-agent-spine-demo`](../agent-spine-demo/README.md), persisted same-session goals, the human-command registry and `/goal` producer, JSONL persistence, keyboard-backed user interaction, a pre-created `main` agent, and [`@deepseek-ai/dsh-tui`](../../ui/tui/README.md). Its `bin` boots a leaf `cordis.yml`.
Use [`@deepseek-ai/dsh-cli-demo`](../cli-demo/README.md) for pipes, scripts, and other non-interactive runs. This package requires a TTY pair and has no line-oriented fallback.
## What it bakes in
| Plugin | Why it is here |
|---|---|
| `@deepseek-ai/dsh-agent-spine-demo` | Shared services, model-facing tools, and one configured `main` agent |
| `@deepseek-ai/dsh-commands` | Human-only discovery and dispatch consumed by the TUI and command plugins |
| `@deepseek-ai/dsh-command-goal` | Direct `/goal` status and mutation over the spine's persisted-goal stack |
| `@deepseek-ai/dsh-session-persistence-jsonl` | Durable session log under `persistenceRoot` |
| `@deepseek-ai/dsh-user-interaction` | Provider-neutral human question service |
| `@deepseek-ai/dsh-tui` | Full-screen transcript, editor, tool cards, plan, and question overlays |
| `@deepseek-ai/dsh-tool-ask-user` | Model-facing `ask_user_question` tool |
Swappable LLM, bash, filesystem, and other capability providers remain in the leaf config. `@cordisjs/plugin-hmr` also remains a leaf-only development entry because it requires Loader internals.
## Config
| Key | Default | Routed to |
|---|---|---|
| `provider` | required | Configured `main` agent provider |
| `model` | required | Configured `main` agent model |
| `maxParallelToolCalls` | agent-loop default | Bundled loop concurrency cap |
| `persona` | — | System-prompt persona template |
| `toolOrder` | lexicographic | Explicit model-facing tool order |
| `tools` | owner default | Tool presentation mode |
| `dshHome` | owner default | Harness home used by bash and skills |
| `skills` | owner defaults | Skill registry, local provider, and tool config |
| `toolBash` | owner defaults | Model-facing bash tool config |
| `toolTasks` | owner defaults | Background-task control-tool config, or `false` |
| `goals` | owner defaults | Persisted goal-domain and model-tool config; `false` removes the goal stack and `/goal` producer |
| `workspaceContext` | required | Workspace-instruction config, or `false` |
| `persistenceRoot` | `./.sessions` | JSONL persistence root |
| `persistenceCompression` | `'zstd'` | JSONL artifact encoding (`'zstd'` or raw `'none'`) |
| `welcome` | `ready.` | TUI subtitle |
| `ui` | owner defaults | TUI presentation settings such as reasoning, color, and card height |
| `resumeSessionId` | — | Exact persisted session to resume |
Fresh runs mint a `main-session-<uuid>` session id and pass it to both the TUI and configured agent. Resumed runs bind both components to `resumeSessionId`. The TUI mounts before the spine so it can render a matching config-start failure instead of leaving a blank terminal.
## The bin
`dsh-tui-demo [path-to-cordis.yml]` defaults to `./cordis.yml`, loads the optional cwd `.env`, boots the Cordis Loader, and waits for the full plugin tree. Bare package specifiers require `node --expose-internals` or the Loader's optional native fallback; the repository scripts use `--expose-internals`.
## Example leaf
```yaml
- id: llm-deepseek
name: '@deepseek-ai/dsh-llm-deepseek'
config:
apiKey: !!js process.env.DEEPSEEK_API_KEY
- id: bash
name: '@deepseek-ai/dsh-bash-local'
- id: tui-agent
name: '@deepseek-ai/dsh-tui-demo'
config:
provider: deepseek
model: deepseek-v4-flash
workspaceContext:
maxBytes: 65536
welcome: 'Coding agent ready.'
ui:
showReasoning: true
```
## Model Experience
### Interactive terminal turn
#### What the model sees
Each non-empty non-command editor submission becomes a user message; a submission during a running turn becomes steering. Slash-command input and output remain human-only, while accepted `/goal` mutations append domain-owned model-visible state. The shared spine contributes the configured persona, workspace instructions, skill catalog, goal controls, and visible tool schemas. TUI rendering itself is not model-visible.
#### Token effect
User, assistant, and tool history grows under the normal session and compaction rules. Headers, cards, plans, Markdown styling, and keybindings add no tokens.
#### KV Cache effect
Append-only while the composed prompt, schemas, route, and retained history prefix remain stable. Composition changes and compaction can invalidate reuse from the first changed token.
### Human-question answer
#### What the model sees
`ask_user_question` retains the tool call and the compact answer or stable interruption error defined by `dsh-tool-ask-user`. The question overlay is terminal-only.
#### Token effect
Only the completed or failed tool result adds retained tokens.
#### KV Cache effect
Append-only; the answer follows the reusable request prefix.
## Known Limitations and Deferred Work
- **TTY-only** — stdin and stdout must both be terminals; automation uses `dsh-cli-demo`.
- **One configured terminal session** — the transcript and editor bind to one exact session id.
- **The app cluster is fixed** — JSONL persistence and ask-user tooling are baked in; different policy requires another composition.
- **Approval is separate** — this app answers `ctx.userInteraction`, not `ctx.approval`; permission prompts require an approval service and answerer.
