Plugin hooks fail to load - Hooks use a matcher + hooks array.

[kergekacsa]

The plugin v2.10 fails to load in Claude Code due to invalid hook event name and missing hooks array in hooks/hooks.json.
Claude Code v2.1.92 with the latest v2.10 version throws an error:

`Settings Error

/workspace/.claude/settings.json
└ hooks
├ PostToolUse
│ └ 0
│ └ hooks: Expected array, but received undefined
├ PreCommit: Invalid key in record
└ SessionStart

└ hooks: Expected array, but received undefined

Hooks use a matcher + hooks array. The matcher is a string: a tool name ("Bash"), pipe-separated list
("Edit|Write"), or empty to match all. Example: {"PostToolUse": [{"matcher": "Edit|Write", "hooks": [{"type":
"command", "command": "echo Done"}]}]}

You can try updating your .claude/settings.json to as follows:

{
  "hooks": {
    "PostToolUse": [
      {
        "matcher": "Edit|Write|Bash",
        "hooks": [
          {
            "type": "command",
            "command": "code-review-graph update --quiet"
          }
        ]
      }
    ],
    "SessionStart": [
      {
        "matcher": "",
        "hooks": [
          {
            "type": "command",
            "command": "code-review-graph status --json"
          }
        ]
      }
    ]
  }
}

I did that, but that way the PreCommit functionaltiy is gone and code-review-graph writes it back on update so it only a temporary half-solution :(

2. Continue without these settings`

I am also facing the same issue, not sure how much time would it take to get this fixed.

PR #141 addresses this — it rewrites generate_hooks_config() to use the correct Claude Code hook schema (nested hooks array, valid event types only). Tracking for the next release.

it actually replace the current hooks as well
