Tool Best Practices:

"Always use Grep for search tasks. NEVER invoke grep or rg as a Bash command."
"Batch independent tool calls in a single response."
MultiEdit for multiple changes to single files

Analysis: Both offer comprehensive toolsets. NovaKit's LSP tools and vector_search are unique. Claude Code's Task tool enables sophisticated subagent delegation.

Hooks and Automation

NovaKit CLI

No native hooks system
Standard tool confirmations

Claude Code Hooks

Hooks execute shell commands automatically at lifecycle events:

Hook Event	Trigger
PreToolUse	Before tool execution
PostToolUse	After tool completion
UserPromptSubmit	When user sends prompt
SessionStart	Session initialization

Configuration:

{
  "hooks": {
    "PreToolUse": [
      {
        "matcher": "Bash*",
        "hooks": [
          {
            "type": "command",
            "command": "echo 'Running bash command'"
          }
        ]
      }
    ]
  }
}

Analysis: Claude Code's hooks system enables guaranteed automation without relying on the model to "remember" tasks—a powerful advantage for consistent workflows.

Skills and Subagents

NovaKit CLI

Custom agents via ~/.novakit/agents.json
JSON-based configuration
Model selection per agent

Claude Code Skills

Skills are modular capabilities Claude autonomously invokes based on context:

Location: .claude/skills/ or ~/.claude/skills/
Structure: Directory with SKILL.md + optional scripts
Discovery: Automatic based on description

Subagents via Task tool:

Specialized instances for code review, debugging, architecture
Context isolation for independent verification
Parallel processing with multiple instances

Analysis: Claude Code's skills are model-invoked (autonomous), while NovaKit's agents are user-invoked. Claude Code's subagent pattern enables sophisticated verification workflows.
