Zesdex

Autonomous AI coding agent in a terminal-based TUI.

Zesdex is a Rust-powered AI assistant that operates directly in your terminal via a rich TUI interface. It combines large language model intelligence with a comprehensive set of tools to explore, understand, and modify codebases autonomously — with built-in guardrails at every layer.

Features

Core

• TUI Interface — Full-screen terminal UI with chat panel, input bar, and status bar built with ratatui and crossterm.
• Daemon Architecture — Run as a background daemon with client attach/detach via Unix domain sockets. The daemon processes state; clients only render.
• IPC Protocol — Bidirectional state synchronization between daemon and client processes with diff-based updates.
• Provider Agnostic — Configurable AI model providers with dynamic model selection, per-role temperature/token limits, and API key management.

Tool System (34 built-in tools)

Category	Tools
Filesystem	read, write, edit, delete
Search	grep (recursive text), glob (file patterns)
Shell	bash, bash_output, bash_kill
Git	git_operator, git_worktree, git_cred
Memory	remember, recall, forget
Planning	plan_enter, plan_ready, seqthink
Workflow	workflow_run, note_finding, company_pipeline
Utility	cd, dir_list, dir_cache_update, pong, todowrite, todofinish
LSP	lsp_connect, lsp_diagnostics, lsp_hover, lsp_completion, lsp_definition, lsp_references, lsp_disconnect

Intelligence

• Company Pipeline — Autonomous agent orchestration modeled as a company with specialized divisions. The CEO (main agent) automatically delegates work to 5 divisions in sequence:

  Strategy → Engineering → Quality → Security → Documentation
  

  Each division has a dedicated role, toolset, and system prompt. Controlled via /pipeline full|quick|skip.

• Workflow Engine — Orchestrate complex multi-step tasks with parallel sub-agents, pipelines, and phased execution. Spawn independent workers that share findings in real-time.

• Self-Learning — Persistent memory system that stores lessons, references, and project knowledge across sessions. Memories include provenance tracking, lifecycle management, and scope isolation.

• Self-Review — Review subagents trigger automatically after each code edit (inline) and at turn completion (background). Three types: code quality, architecture, and security.

• Self-Healing — On build/test failures, spawns a sub-agent with the error context to autonomously fix issues before reporting them to the user.

• MCP Support — Model Context Protocol integration for connecting to external AI tool servers.

• Sequential Thinking — Chain-of-thought reasoning tool for step-by-step problem decomposition.

• Session Locking — Prevents multiple processes from operating on the same session directory.

Session Management

• Multiple concurrent sessions with history, rewind, and transcript persistence.
• Per-session edit logs with full change tracking.
• Session archival and summary generation.

Configuration

All configuration lives in ~/.config/zesdex/ (or platform equivalent via the dirs crate).

File	Purpose
settings.json	Provider selection, model, temperature, max tokens, review settings, workflow concurrency
app_config.json	AI provider definitions (name, API base URL, auth type, default model)
memory/	Persistent lesson and reference storage (Markdown with YAML frontmatter)
sessions/	Per-session transcripts, edit logs, and activity data
run/	Unix domain sockets for daemon mode

Provider Configuration

Providers are defined in app_config.json:

{
  "providers": {
    "my-provider": {
      "api_base": "https://api.example.com/v1",
      "api_key_env": "MY_API_KEY",
      "default_model": "model-name"
    }
  },
  "model_roles": {
    "default": {
      "provider": "my-provider",
      "model": "model-name",
      "max_tokens": 8192,
      "temperature": 0.7
    }
  },
  "default_provider": "my-provider",
  "default_model": "model-name"
}

Settings

Key settings in settings.json:

Setting	Default	Description
review_enabled	true	Enable self-review after tool execution
review_max_lessons_per_run	5	Max lessons loaded per review cycle
adaptive_review_max_skip	3	Consecutive passes before skipping review
verify_command	null	Optional command to verify changes
workflow_max_concurrency	5	Max parallel sub-agents in workflows
session_archive_enabled	true	Auto-archive completed sessions

Installation

Prerequisites

• Rust 2021 edition toolchain (rustup)

Build from Source

git clone <repository-url>
cd zesdex
cargo build --release
./target/release/zesdex

---

Development

Commit Convention

Project ini menggunakan Conventional Commits untuk otomatis menentukan versi rilis (melalui semantic-release).

Format:

<type>(<scope>): <description>

[optional body]

[optional footer]

<type> — menentukan bump version:

Type	Bump	Keterangan
feat	minor	Fitur baru
fix	patch	Perbaikan bug
chore	patch	Tugas maintenance, refactor ringan
docs	patch	Perubahan dokumentasi
refactor	patch	Refactor kode (tanpa perubahan fungsional)
test	patch	Penambahan atau perbaikan test
style	patch	Perubahan formatting, whitespace, dll
perf	patch	Optimasi performa
ci	patch	Perubahan CI/CD

BREAKING CHANGE pada body commit → major (apa pun typenya).

Contoh:

feat(agent): add workspace-aware file search

Implement context-aware search scoped to current workspace directory.

BREAKING CHANGE: search results now filter by workspace scope.

fix(ipc): handle partial frame on unix socket reconnect

chore: update rustls to 0.23

Release Workflow

Push ke branch main akan memicu:

1. CI — cargo build --release + cargo test
2. Semantic Release — analisis commit → update Cargo.toml + CHANGELOG.md → git tag → GitHub Release dengan binary
