Hook Event Matrix

Syllago maps each provider’s native hook event names to canonical events — a shared vocabulary that makes hooks portable across tools. This page shows which events each provider supports and what they call them.

How to read this table

Canonical name: The syllago-standard event name used in .syllago.yaml
Provider columns: The native event name each provider uses, or — if unsupported
Category: Groups related events (lifecycle, tool, context, etc.)

Collaboration

Multi-agent coordination events. Fires when teammate agents become idle or available.

Canonical Event	Claude Code	Gemini CLI	Cursor	Devin Desktop	Copilot CLI	Kiro	Factory Droid	Pi	Crush

Config

Configuration file change detection. Fires when settings files are modified during a session.

Context

Events related to context management — compaction, instruction loading, and context window maintenance.

Hooks supported, event mappings pending: Codex, Cline, Amp. These providers support hooks, but syllago does not yet map their event names. Hook conversion is best-effort.
