About ForgeCode
ForgeCode is a coding agent that lives in the shell. You type a colon in ZSH to talk to it, and your existing aliases and Oh My Zsh plugins keep working. It is installed with a single curl command.
Work is split between specialised sub-agents for research, planning and execution, each with its own limited context. You can mix models within one session, for example a thinking model for planning and a faster model for writing code. An optional ForgeCode Services layer adds a context engine for large codebases.
Strengths
- Integrates directly into ZSH without replacing your shell setup
- Switch between models mid-session for different tasks
- Separate sub-agents for research, planning and execution
Limitations
- Built around ZSH, so other shells get less benefit
- Some context features depend on the separate ForgeCode Services
