Coding Tools
AI coding harnesses, assistants, and IDE integrations organized by workflow, provider fit, permissions, and verification behavior.
What Are Coding Tools?
Coding tools are AI assistants that work alongside you during development. You remain in control—the AI suggests, explains, and helps implement, but you review and approve every change.
These differ from agentic tools which run autonomously.
Canonical tool docs live in /tools/. This hub organizes coding assistants by workflow.
Available Tools
OpenAI Codex
Cloud-native agent with parallel worktrees and real-time dashboard.
Harnesses for GLM-5.2 and broad providers
- Pi — minimal programmable terminal harness
- ZCode — integrated GLM-5.2-native desktop harness
- OpenCode — provider-neutral harness with agents and granular permissions
- Pi vs ZCode vs OpenCode — same-model comparison and test card
Quick Comparison
| Tool | Type | Cost | Best For |

| Codex | Cloud agent | Credits + subscription | Parallel workflows, team coordination |
| Pi | Terminal harness | Provider/API dependent | Custom tools, extensions, sessions, compaction |
| ZCode | Desktop ADE | GLM account/plan dependent | Integrated GLM-5.2 and long-running goals |
| OpenCode | Open-source harness | Zen, BYO API, or supported plan | Broad providers, permissions, IDE/GitHub workflows |
