v1.2.2 · First Sidekick: Forge

Reduce Claude Code Costs by up to 70%
Give Claude the Sidekick it's Missing

Offload Claude by giving it top coding agent Sidekicks like ForgeCode (#2, #3 and #6 in Terminal Bench 2.0) and super cost-effective models like Qwen3 Coder Plus. Let Claude delegate all implementation work — while you interact only with Claude.

Claude Code Plugin Forge — TB 2.0 #2 OpenRouter Auto-Install

Maximum Delegation

Claude delegates all file writes, edits, test runs, and commits. You get faster results without Claude burning context on execution.

Auto-Install

Each Sidekick installs itself on the first Claude session after the plugin is enabled. No manual setup required.

Context Continuity

AGENTS.md keeps each Sidekick fully aware of project goals, stack, and conventions on every invocation.

Failure Recovery

12-failure-type recovery playbook built into Claude's orchestration skill. 402s, 429s, PATH issues — handled automatically.

Your Sidekicks

Each Sidekick is a specialized AI coding agent. More are coming.

Three steps, then delegate

After installation, Claude walks you through everything.

1

Plugin Installs Forge

On first session start after enabling the plugin, ForgeCode is downloaded and added to your PATH automatically.

# Runs automatically on first session
curl -fsSL https://forgecode.dev/cli | sh
2

Add OpenRouter Key

Claude guides you to sign up at openrouter.ai and add a small credit. $5 goes a long way with Qwen3 Coder Plus.

# Claude configures this for you
Provider: open_router
Model: qwen/qwen3-coder-plus
3

Claude Delegates

From this point on, Claude acts as orchestrator. All file writes, tests, and commits go to Forge. You stay in Claude.

# Forge receives structured prompts
forge -p "implement X, test Y, commit"
