FAQPage Schema

How do I integrate custom skills with Claude Code hooks for automation?▼

Yes, you can enforce security checks before tool usage by hooking custom skills into the PreToolUse event. This allows you to define expected input and output schemas to validate tool actions and execute security validation logic.

What are the available hook events for context management in the Gemini CLI?▼

The Gemini CLI supports 12 hook events for context management, including SessionStart for context injection and PostSession for summarization. These events allow you to define clear input and output schemas to enrich session context.

How do I inject context into a session using Claude Code hooks?▼

You inject context into a session by hooking a custom skill into the SessionStart event. This pattern enriches the session with necessary background information at initialization using defined input and output schemas.

Can I perform pre-tool validation using Claude Code hook events?▼

What is the best way to track costs and summarize sessions with hook integration?▼

The best way to track costs and summarize sessions is by building custom skills that hook into post-session events. This approach uses detailed input and output schemas to automate post-session summarization and cost tracking.
