forge-orchestrator

Orchestrate Claude Code, Codex CLI, and Gemini CLI on shared repos — single Rust binary, zero deps.

Multi-agent inside a single tool works fine. Claude Code runs 20 subagents and they stay aligned because the tool manages that orchestration internally. The problem is multi-tool: Claude Code, Codex CLI, and Gemini CLI on the same repo with no shared state. That's what the orchestrator solves.

It adds file locking, knowledge capture, task planning, drift detection, and multi-tool orchestration to your development workflow. Three tools reading from and writing to a single state directory. An 11-tool MCP server exposes the full orchestration state to any connected AI client.

The orchestrator exists because I ran two AI tools on the same codebase and watched them fail in the same ways human teams fail. Claude refactored a module. Codex updated tests against the pre-refactor interface. Both saved. Tests failed. Neither tool knew the other existed. I'd spent 23 years watching this exact scenario with talented human teams. The solution was always the same: orchestration infrastructure.

Install

curl -fsSL https://forge.nxtg.ai/install.sh | sh
forge init

Single binary. 4.7 MB. No runtime dependencies.

Quick Demo

Four commands from zero to task board:

# 1. Initialize — creates .forge/ directory with state, event log, knowledge base
forge init

# 2. Configure the AI brain — choose 'openai' (needs API key) or 'rule-based' (free)
forge config brain openai

# 3. Generate tasks — reads your SPEC.md or README, creates dependency-aware task graph
forge plan --generate

# 4. See the result — task board with assignments, dependencies, and project health
forge status

From here you can:

• forge run — execute tasks headlessly (autonomous mode, great for CI)
• forge dashboard --pty — launch the TUI dashboard with interactive agent panes

Real-World Result: Stargate Mode

From a 94-line specification, the orchestrator coordinated three AI coding tools to build a complete CLI toolkit:

SPEC.md (94 lines) → forge plan --generate → 15 tasks

Claude Code:  6 design tasks     → completed
Codex CLI:    6 implementation   → completed
Gemini CLI:   3 test/doc tasks   → completed

Result: 5,306 lines of working code
        10 auto-committed git entries
        13 Python files (CLI + tests)
        Zero file conflicts

Three companies. Three tools. One orchestrator. One command:

forge dashboard --pty

What You Get

forge ship                     # Release ceremony: changelog, archive, tag

Architecture

The orchestrator is the policy core of Forge. All governance rules, file locks, and orchestration logic live here. The plugin (L1: Vibe Coder) and UI (L3: Ship Lord) are adapter surfaces. They present the orchestrator's state through different interfaces but don't make policy decisions.

Communication: .forge/ filesystem + MCP stdio. No daemon. No database. State is files.

Tool adapters: Claude Code uses MCP stdio. Codex CLI and Gemini CLI use filesystem conventions. Each tool reads its own config format. No Forge-specific configuration language.

How File Locking Works

File locking exists because I've watched teams lose days to conflicting edits.

When Claude Code starts editing a file, the orchestrator acquires an exclusive lock in .forge/locks/. Codex CLI requesting the same file is queued with a notification of who holds the lock. Locks include timeouts (crashed tools don't hold locks forever) and deadlock detection.

378 tests cover concurrent access, timeout behavior, multi-adapter locking, and edge cases.

How the Knowledge Flywheel Works

The knowledge flywheel exists because I've watched decisions evaporate between sprints.

Every decision, pattern, and learning from tool sessions is captured in .forge/knowledge/. Entries are auto-classified by category. Search across sessions and across tools. Knowledge captured during a Claude Code session is available to Codex CLI the next day.

After a week, the system knows your conventions better than you remember them. New sessions start with context instead of from scratch.

Upgrade Path

The TUI dashboard shows everything. Forge UI shows it better.

Visual dashboards. Governance HUD. Real-time agent collaboration network. And the Infinity Terminal: sessions that survive browser close, network drops, and server restarts. If you've lost a 3-hour agent session to a disconnected SSH pipe, you know why this matters.
