overview

overview is a command for Claude Code from ruvnet/ruv-FANN. It costs 0 tokens per session (392 once invoked), scanned A, a copy of overview, MIT.

A collection of automatic actions, called hooks, that run around coding-agent operations. They can check edits and commands, format changed code, record results, preserve session state, and track coordinated agents.

In plain words
What is it for?
Use it to validate file changes, check command safety, format code, cache searches, save session summaries, and monitor task progress.
Why use it?
It reduces repetitive checks and helps keep useful context when work continues across operations or sessions.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

overview scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to overview — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Claude Code Hooks for claude-flow

Purpose

Automatically coordinate, format, and learn from Claude Code operations using hooks.

Available Hooks

Pre-Operation Hooks

  • pre-edit: Validate and assign agents before file modifications
  • pre-bash: Check command safety and resource requirements
  • pre-task: Auto-spawn agents for complex tasks

Post-Operation Hooks

  • post-edit: Auto-format code and train neural patterns
  • post-bash: Log execution and update metrics
  • post-search: Cache results and improve search patterns

MCP Integration Hooks

  • mcp-initialized: Persist swarm configuration
  • agent-spawned: Update agent roster
  • task-orchestrated: Monitor task progress
  • neural-trained: Save pattern improvements

Session Hooks

  • notify: Custom notifications with swarm status
  • session-end: Generate summary and save state
  • session-restore: Load previous session state

Configuration

Hooks are configured in .claude/settings.json:

{
  "hooks": {
    "PreToolUse": [
      {
        "matcher": "^(Write|Edit|MultiEdit)$",
        "hooks": [{
          "type": "command",
          "command": "npx claude-flow hook pre-edit --file '${tool.params.file_path}'"
        }]
      }
    ]
  }
}

Benefits

  • 🤖 Automatic agent assignment based on file type
  • 🎨 Consistent code formatting
  • 🧠 Continuous neural pattern improvement
  • 💾 Cross-session memory persistence
  • 📊 Performance metrics tracking

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

overview is a command published in the GitHub repository ruvnet/ruv-FANN (378 stars, last pushed 28d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 392 tokens. A static security scan graded it A with 0 findings. It is 100% identical to overview, differing in 0 lines, and is treated as a copy.
