overview

A collection of hooks that run around Claude Code operations such as editing files, running commands, searching, and coordinating agents. Hooks are automatic actions triggered by those events.

In plain words
What is it for?
Use it to validate edits and commands, assign agents, format code, record execution metrics, cache searches, share coordination memory, track tasks, and save or restore session state.
Why use it?
It keeps routine checks, formatting, logging, memory updates, and session recovery from having to be handled manually each time.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 962 The whole file, excluding the scripts and references it only reads on demand.

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 2d 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.

Claude Code Hooks for claude-flow

Purpose

Automatically coordinate, format, and learn from Claude Code operations using hooks with MCP tool integration.

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, train neural patterns, update memory
  • 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 and memory
  • task-orchestrated: Monitor task progress through memory
  • neural-trained: Save pattern improvements

Memory Coordination Hooks

  • memory-write: Triggered when agents write to coordination memory
  • memory-read: Triggered when agents read from coordination memory
  • memory-sync: Synchronize memory across swarm agents

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}' --memory-key 'swarm/editor/current'"
        }]
      }
    ],
    "PostToolUse": [
      {
        "matcher": "^(Write|Edit|MultiEdit)$",
        "hooks": [{
          "type": "command",
          "command": "npx claude-flow hook post-edit --file '${tool.params.file_path}' --memory-key 'swarm/editor/complete'"
        }]
      }
    ]
  }
}

MCP Tool Integration in Hooks

Hooks automatically trigger MCP tools for coordination:

// Pre-task hook spawns agents
npx claude-flow hook pre-task --description "[task]"
// Internally calls:
mcp__claude-flow__agent_spawn { type: "appropriate-agent" }

// Post-edit hook updates memory
npx claude-flow hook post-edit --file "[file]"
// Internally calls:
mcp__claude-flow__memory_usage {
  action: "store",
  key: "swarm/editor/[file]",
  namespace: "coordination",
  value: JSON.stringify({ file, changes, timestamp })
}

// Session-end hook persists state
npx claude-flow hook session-end
// Internally calls:
mcp__claude-flow__memory_persist { sessionId: "[session-id]" }

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 natea/ExoMind (21 stars, last pushed 10mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 962 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
