Creates and manages isolated tmux sessions for AI coding agents (Claude Code, OpenCode, Mistral Vibe, Gemini CLI, etc.) through a Rust-based wrapper that abstracts tmux complexity. Each session is assigned a unique 8-character UUID and human-readable title, with lifecycle management (attach/detach/kill) exposed via CLI and TUI. The system maintains session state in persistent storage keyed by profile, enabling recovery and resumption across terminal restarts.
Unique: Wraps tmux with domain-specific abstractions (Instance, GroupTree, Storage) designed explicitly for AI agent lifecycle management, rather than generic terminal multiplexing. Implements automatic status detection (Running/Waiting/Idle) by parsing agent-specific process output patterns, and provides hierarchical session grouping via a tree structure stored in profile-isolated persistent storage.
vs alternatives: Simpler than managing raw tmux for multi-agent workflows and more specialized than generic terminal multiplexers like Zellij or screen, with built-in awareness of AI agent state transitions.
Maintains multiple independent profiles (contexts) where each profile has its own session storage, worktree configuration, and Docker sandbox settings. Profiles are stored in a configuration directory and loaded on-demand, enabling developers to switch between completely isolated workspaces (e.g., 'project-a', 'project-b', 'experimentation') without session collision. The Storage system (src/session/storage.rs) provides profile-keyed persistence with automatic directory creation and cleanup.
Unique: Implements profile isolation at the storage layer (src/session/storage.rs) with automatic directory scoping, allowing complete session independence without manual path management. Profiles are composable with worktree and Docker sandbox configurations, enabling per-project agent behavior customization.
vs alternatives: More lightweight than containerized workspace solutions (Docker Compose) while providing stronger isolation than simple directory-based organization, with explicit profile switching semantics.
Supports multiple AI coding agent providers (Claude Code, OpenCode, Mistral Vibe, Codex CLI, Gemini CLI, Pi.dev, GitHub Copilot CLI, Factory Droid Coding) with agent-specific configuration and status detection patterns. Each agent type has a profile in AGENTS.md defining its CLI invocation, output patterns for status detection, and configuration requirements. The system abstracts agent differences, allowing users to create sessions for any supported agent without learning provider-specific details.
Unique: Implements agent abstraction via AGENTS.md configuration file defining CLI invocation, status detection patterns, and requirements for each supported provider. Allows users to create sessions for any agent without provider-specific code, with extensible status detection based on agent output patterns.
vs alternatives: More flexible than single-agent tools and more practical than requiring users to manage agent CLIs directly, with explicit support for multiple providers and automatic status detection.
Persists session metadata (title, agent type, working directory, group membership, parent-child relationships) to disk in profile-scoped storage, enabling sessions to survive terminal restarts, SSH disconnections, and system reboots. When aoe is restarted, it reads session metadata from storage and can reattach to existing tmux sessions or recreate them if they were lost. The system maintains a session index for fast lookup and supports session cleanup (removing orphaned metadata for deleted sessions).
Unique: Implements profile-scoped session persistence (src/session/storage.rs) with automatic metadata serialization and recovery on startup. Maintains a session index for fast lookup and supports orphaned session cleanup, enabling seamless session recovery across system restarts.
vs alternatives: More reliable than tmux's default session persistence (which is lost on server restart) and more lightweight than full database-backed session management, with explicit profile isolation.
Allows users to define session templates and default configurations in YAML files (profile configuration, worktree settings, Docker sandbox config, agent defaults). When creating a session, users can reference a template to inherit configuration, reducing repetitive setup. Configuration is hierarchical: global defaults, profile-level defaults, and session-level overrides. The system validates configuration on load and provides helpful error messages for invalid settings.
Unique: Implements hierarchical configuration (global, profile, session) with YAML-based templates and defaults, enabling teams to standardize session setup without code changes. Configuration is profile-scoped and supports overrides at multiple levels.
vs alternatives: More flexible than hardcoded defaults and more practical than manual configuration for each session, with explicit support for team-wide standardization.
Organizes sessions into a tree structure (GroupTree in src/session/group_tree.rs) where sessions can be nested under logical groups (e.g., 'frontend', 'backend', 'experiments'). Groups are displayed hierarchically in the TUI and can be collapsed/expanded for navigation. The system supports sub-sessions and parent-child relationships, enabling developers to logically cluster related agent sessions and manage them as units.
Unique: Implements a tree-based session organization model (GroupTree) that persists group membership in profile storage, enabling logical clustering without requiring separate configuration files. Supports sub-sessions and parent-child relationships, allowing developers to fork sessions and maintain lineage.
vs alternatives: More structured than flat session lists (like tmux's default) while simpler than full project management systems, with explicit parent-child semantics for session forking workflows.
Monitors tmux session processes to automatically detect and classify agent state as Running, Waiting, or Idle by parsing agent-specific output patterns and process introspection. The status detection implementation (src/session/instance.rs and src/tmux/) analyzes terminal output and process trees to infer whether an agent is actively executing code, waiting for user input, or idle. Status is cached and updated on-demand to avoid expensive polling.
Unique: Implements agent-specific status detection patterns (defined in AGENTS.md) that parse output from different AI coding agents (Claude Code, OpenCode, Mistral Vibe, Gemini CLI, etc.) rather than generic process state. Uses process tree introspection combined with terminal output analysis to infer semantic state (Running vs Waiting vs Idle).
vs alternatives: More intelligent than simple process state checks (running/stopped) and more practical than requiring explicit status reporting from agents, with built-in awareness of multiple agent types.
Creates and manages Git worktrees for each session, enabling parallel development branches without switching the main working directory. When a session is created with worktree support, the system automatically creates a new worktree at a path derived from a configurable template (e.g., ~/.agent-of-empires/worktrees/{profile}/{session-id}), checks out a specified branch, and cleans up the worktree when the session is destroyed. This allows multiple agents to work on different branches simultaneously without file system conflicts.
Unique: Integrates Git worktree management directly into the session lifecycle (src/git/), with automatic creation and cleanup tied to session creation/destruction. Uses configurable path templates to organize worktrees by profile and session ID, enabling scalable parallel development without manual git commands.
vs alternatives: More integrated than manual git worktree commands and more flexible than Docker-based isolation, with explicit support for multi-agent parallel development on the same repository.

Generates code suggestions as developers type by leveraging OpenAI Codex, a large language model trained on public code repositories. The system integrates directly into editor processes (VS Code, JetBrains, Neovim) via language server protocol extensions, streaming partial completions to the editor buffer with latency-optimized inference. Suggestions are ranked by relevance scoring and filtered based on cursor context, file syntax, and surrounding code patterns.
