tui

A development guide for Splitrail's terminal user interface, the text-based screen shown in a command-line window, and its live file-watching system. It covers statistics displays, session views, input handling, and updates when analyzer files change.

In plain words
What is it for?
Use it when modifying Splitrail's terminal screens, statistics views, session loading, file watchers, or analyzer support for live updates.
Why use it?
It helps developers change the interface without breaking real-time updates or loading more session data into memory than necessary. It also explains how file changes flow into refreshed statistics.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

tui scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Real-Time Monitoring & TUI

Splitrail provides a terminal UI with live updates when analyzer data files change.

Source Files

  • src/tui.rs - TUI entry point and rendering
  • src/tui/logic.rs - TUI state management and input handling
  • src/watcher.rs - File watching implementation

Components

FileWatcher (src/watcher.rs)

Watches analyzer data directories for changes using the notify crate. Triggers incremental re-parsing on file changes and updates TUI via channels.

RealtimeStatsManager

Coordinates real-time updates: background file watching, auto-upload to Splitrail Cloud (if configured), and stats updates to TUI via tokio::sync::watch.

TUI (src/tui.rs, src/tui/logic.rs)

Terminal interface using ratatui:

  • Daily stats view with date navigation
  • Session view with lazy message loading
  • Real-time stats refresh

Key Patterns

  • Channel-based updates - Stats flow through tokio::sync::watch channels
  • Lazy message loading - Messages loaded on-demand for session view to reduce memory

Adding Watch Support to an Analyzer

Implement get_watch_directories() in your analyzer to return root directories for file watching. See src/analyzer.rs for the trait definition.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

tui is a skill published in the GitHub repository Piebald-AI/splitrail (218 stars, last pushed 12d ago), licensed MIT. It adds 30 tokens to every session and 319 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
