Ratatui-based TUI dashboard with real-time metrics for Zeph.

Overview

Provides a terminal UI for monitoring the Zeph agent in real time. Built on ratatui and crossterm, it renders live token usage, latency histograms, conversation history, and skill activity. The skills panel includes Wilson score confidence bars showing each skill's posterior reliability estimate. Feature-gated behind tui.

Key Modules

  • appApp state machine driving the render/event loop; uses a dirty flag to skip redraws when state is unchanged, reducing idle CPU usage
  • channelTuiChannel implementing the Channel trait for agent I/O
  • command_palette — fuzzy-matching command palette with daemon commands (daemon:connect, daemon:disconnect, daemon:status), action commands (app:quit, app:help, session:new, app:theme), and keybinding hints
  • eventAgentEvent, AppEvent, EventReader for async event dispatch
  • file_picker@-triggered fuzzy file search with nucleo-matcher and ignore crate
  • highlight — syntax highlighting for code blocks
  • hyperlink — OSC 8 clickable hyperlinks for bare URLs and markdown links
  • layout — panel arrangement and responsive grid
  • metricsMetricsCollector, MetricsSnapshot for live telemetry; skill confidence bars rendered as [████░░░░] 73% (42 uses) using Wilson score posterior from the skills registry; filter savings percentage shown in the status bar (e.g. Filters: 78%); SEC indicator in status bar shows injection flag count when nonzero
  • theme — color palette and style definitions
  • widgets — reusable ratatui widget components; includes subagents widget with a 5-state FSM panel (ListDetailCreateEditConfirmDelete) for interactive management of sub-agent definition files; security widget renders a side panel with a real-time security event feed (injection flags, exfiltration blocks, quarantine invocations, truncations); plan_view widget renders a live task graph table with per-row status spinners, status colors (Running=Yellow, Completed=Green, Failed=Red), and a 30-second stale cleanup — toggled with p (requires orchestration feature)
  • errorTuiError typed error enum (Io, Channel)

Agents management panel

Press a in the TUI to open the interactive agents panel. It provides full CRUD over sub-agent definition files without leaving the terminal UI:

State Description
List Scrollable list of all discovered definitions with name, scope, model, and permission mode
Detail Full definition view (tools, skills, system prompt, hooks)
Create Inline form wizard — name, description, model, max turns; validates name regex and required fields before writing
Edit Pre-filled form wizard populated from the existing definition
ConfirmDelete Two-step confirmation for non-project-scoped definitions

Keybindings: c — create, e — edit, d — delete, Enter — detail view, Esc — go back.

Graph memory commands

When the graph-memory feature is enabled, the TUI provides /graph slash commands for inspecting the knowledge graph:

Command Description
/graph Show entity, edge, and community counts
/graph entities List all entities with type and last-seen timestamp
/graph facts <entity> Show relationships for a specific entity
/graph communities List detected communities
/graph backfill [--limit N] Process existing messages through graph extraction

[!NOTE] These commands require --features graph-memory (or --features full). The graph must be enabled in config ([memory.graph] enabled = true) or via the --graph-memory CLI flag.

Experiment commands

When the experiments feature is enabled, the TUI provides /experiment slash commands for autonomous self-experimentation:

Command Description
/experiment start [N] Start an experiment session (optional N = max experiments)
/experiment stop Stop the running experiment session
/experiment status Show current experiment session status
/experiment report Print experiment results summary
/experiment best Show the best experiment result

[!NOTE] These commands require --features experiments (or --features full). Experiments must be enabled in config ([experiments] enabled = true).

Debug dump

Enable debug dump mid-session without restarting the agent:

Command Description
/debug-dump Enable debug dump using debug.output_dir from config
/debug-dump <PATH> Enable debug dump writing to a custom directory

Files are written to {output_dir}/{unix_timestamp}/ with numbered request.json, response.txt, and tool-{name}.txt files for each LLM call and tool execution.

Command palette

The command palette is opened with : in normal mode. Type to fuzzy-filter entries, then press Enter to execute.

Entry Description
skill:list List all loaded skills
mcp:list List MCP servers and registered tools
memory:stats Show SQLite message count and vector store status
view:cost Show token usage and cost breakdown
view:tools List available tools
view:config Show active configuration
view:autonomy Show autonomy/trust level
view:filters Display output filter hit rates and invocation counts
graph:stats Show graph memory statistics — requires graph-memory feature
graph:entities List graph entities — requires graph-memory feature
graph:facts Show entity facts (prompts for entity name) — requires graph-memory feature
graph:communities List graph communities — requires graph-memory feature
graph:backfill Backfill graph from existing messages — requires graph-memory feature
scheduler:list List active scheduled tasks (name, kind, mode, next run) — requires scheduler feature
gateway:status Show gateway server state — requires gateway feature
security:events Show security event history
plan:status Print current plan progress to chat
plan:confirm Confirm and execute the pending plan
plan:cancel Cancel the active plan
plan:list List recent plans
plan:toggle Toggle Plan View in the side panel (p shortcut) — requires orchestration feature
experiment:start Start experiment session — requires experiments feature
experiment:stop Stop running experiment — requires experiments feature
experiment:status Show experiment status — requires experiments feature
experiment:report Show experiment results — requires experiments feature
experiment:best Show best experiment result — requires experiments feature
debug:dump Enable debug dump to the configured output directory (equivalent to /debug-dump)
ingest Usage hint for zeph ingest <path>
session:new Start a new conversation session
session:history Browse session history (H shortcut)
daemon:connect Attach to a running daemon — requires daemon feature
daemon:disconnect Detach from daemon
daemon:status Show daemon connection state
app:quit Exit the TUI (q shortcut)
app:help Show keybindings help (? shortcut)
app:theme Toggle dark/light theme

Installation
