kanon

Manage multiple coding-agent settings across multiple diverse machines.

Quick start

kanon init
kanon validate
kanon diff
kanon apply

The settings repository defaults to ~/.config/kanon. Set KANON_HOME or pass --home to point somewhere else. Use kanon pull and kanon push for explicit git sync.

Managed settings

Kanon can render:

• instructions into AGENTS.md and CLAUDE.md
• skills into Codex and Claude skill directories
• MCP server definitions
• hooks
• permissions and Codex rules

The default flow is preview first, then apply. Existing unmanaged files block writes unless --adopt is passed, and overwritten files are backed up under .kanon/backups.

Importing existing settings

kanon import --agent all
kanon import --agent all --write
kanon import --agent all --write --force

Import previews normalize existing Codex and Claude settings into Kanon config. Imported config is neutral by default: instructions, skills, MCP servers, hooks, and permissions are lifted into top-level sections with optional targets when a setting only applies to some agents. Native fields that do not map to the neutral schema are skipped with warnings.

For now, import supports --secret-policy keep only. Secret-looking values are preserved and reported with warnings so you can move them to environment references or another secret manager manually. Future policies for env refs, omission, password managers, and encrypted secrets are tracked in code TODOs.

If both AGENTS.md and CLAUDE.md exist and differ, import stops by default. Re-run with --instruction-policy codex, claude, merge, or skip to choose how to create neutral instructions. --write refuses to replace an existing kanon.yaml; use --force when intentionally re-importing.
