Host setup guides

Daimon closes a capture -> inject loop around whatever agent host you use: a session-end hook writes a checkpoint, a session-start (or per-prompt) hook turns the latest checkpoint into a briefing. Support depth varies by what hook events each host actually exposes.

Host	Install	Capture	Briefing injection	Status
Claude Code	Plugin (/plugin install daimon@daimon) or manual hook/daimon-hooks.py install	SessionEnd hook spawns daimon serialize detached	SessionStart hook injects the briefing; UserPromptSubmit hook adds proactive recall	live-validated daily
Codex	daimon hooks install codex	SessionEnd hook serializes on graceful end; throttled Stop hook covers everything else	SessionStart hook injects via additionalContext	live-validated capture (since 2026-08-06)
Gemini CLI	Manual hook/gemini-hooks.py install (from a clone)	SessionEnd hook spawns daimon serialize once transcript_path is non-empty (gemini-cli v0.21.0 or later; the gemini-cli#14715 stub is fixed there)	SessionStart hook injects via additionalContext	capture unverified: no real Gemini session run through serialize since the upstream fix
Windsurf (Cascade)	daimon hooks install windsurf	Throttled serialize on pre_user_prompt / post_cascade_response(_with_transcript)	None — Cascade has no session-start-equivalent event; the skill instructs the agent to run daimon brief --team in the terminal at session start	live-validated
Kimi Code	daimon hooks install kimi	SessionEnd hook serializes on interactive exit; throttled Stop hook is the only path in print mode	UserPromptSubmit hook injects with your first prompt (no session-start channel)	measured on one live session (2026-09-09)

Three moving parts

Every host setup combines up to three pieces, installed independently:

• Hooks capture your sessions and (where the host supports it) inject the briefing as context. Claude Code gets a packaged plugin; other hosts install standalone hook scripts via daimon hooks install <host> (Windsurf, Codex, Kimi Code) or the manual lifecycle scripts under hook/ (Gemini, and Claude Code without the plugin).
• The skill (daimon skill install <host>) teaches the agent on the other side of the hook how to use what the hooks capture — read the briefing at session start (pulling it with daimon brief --team when the host injects nothing, e.g. Windsurf), treat verbatim items as immutable quotes, verify stale-looking claims before repeating them.
• The daimon CLI is the single source of truth every hook shells out to for serialization, rendering, and storage — install it once (uv tool install 'daimon-briefing[pretty]') and every host's hooks share the same checkpoint store.
