Era Code — OpenCode

This is the OpenCode flavor of Era Code. OpenCode is the original Era Code harness. Era Code supports two AI coding harnesses — OpenCode and Claude Code — and all of Era's shared governance docs (constitution, directives, commands, agents, skills, MCP setup) apply to both. Use the Harness switcher in the top-right navbar to move between the two variants; everything outside these harness pages is shared.

Launch this harness with era-code start, which syncs your OpenCode configuration, builds directives, loads credentials, and spawns OpenCode with Era settings applied.
