Kiro is Kiro's terminal agent: you run kiro-cli in a project, and it reads your .kiro/ steering files and MCP config, then edits code and runs commands using your Kiro plan. HagiCode is a desktop and web workbench that launches kiro-cli as one of its Agent CLIs, adding parallel sessions, proposals and commits. It does not replace Kiro and it does not sell Kiro credits.
If you already work in Kiro and want its agents, steering and hooks in a terminal, stay with Kiro alone. Add HagiCode when you run several tasks at once or want a proposal workflow independent of Kiro's own.
