shennian

Provides a mobile-optimized command-line interface for orchestrating AI agent workflows with real-time interaction and state management. The CLI accepts user commands, routes them through an agent execution pipeline, and maintains session context across multiple turns of interaction. Built as a Node.js-based console application that bridges user input to underlying agent logic with minimal latency.

Implements a command parser that tokenizes user input, validates against a registered command schema, and routes execution to appropriate agent handlers. The system likely uses a lexer-based approach or regex pattern matching to extract command intent and parameters, then dispatches to handler functions with type-checked arguments. Supports both simple single-word commands and complex multi-argument operations with optional flags.

Maintains user session state across multiple CLI interactions, preserving agent execution history, variable bindings, and conversation context. The implementation likely uses an in-memory session store or file-based persistence layer that tracks command history, agent responses, and user-defined variables. Enables multi-turn agent interactions where later commands can reference results from previous operations.

Executes agent operations with comprehensive error handling, timeout management, and graceful degradation. The system wraps agent handler invocations in try-catch blocks, implements configurable timeout thresholds, and provides structured error reporting with stack traces and context information. Failed operations can trigger fallback handlers or retry logic based on error classification.

Renders agent responses and CLI output in a mobile-friendly format with responsive text wrapping, touch-friendly spacing, and reduced visual complexity. The implementation likely uses ANSI color codes and terminal width detection to adapt output to small screens, avoiding horizontal scrolling and multi-column layouts that are difficult on mobile terminals. Supports both plain text and formatted output modes.

Distributes the Shennian CLI as an npm package with standard Node.js package management, enabling one-command installation via `npm install -g shennian` or local project installation. The package includes dependency declarations, version management, and semantic versioning for compatibility tracking. Installation provides CLI entry points and shell command aliases for easy invocation.

Provides abstraction layer for connecting to various agent backend implementations, supporting multiple agent frameworks or custom agent services. The CLI likely defines a plugin or adapter interface that allows different agent backends (local, remote API, specific frameworks) to be swapped without changing CLI code. Communication may use HTTP, gRPC, or local process invocation depending on backend type.
