hooks/hooks.json format bug: `[]` should be `{"hooks": {}}` — 4 vertical plugins fail to load

[guanlixue09-bit]

Bug

After running claude plugin install for all 17 plugins in this marketplace, 4 of them fail to load with:

Hook load failed: [
  {
    "expected": "record",
    "code": "invalid_type",
    "path": [],
    "message": "Invalid input: expected record, received array"
  }
]

Affected plugins

• financial-analysis (the core base — most impactful, blocks downstream usage)
• equity-research
• private-equity
• wealth-management

Root cause

The hooks/hooks.json file in these 4 plugins contains an empty array:

[]

But Claude Code's plugin loader expects an object with a hooks field:

{
  "hooks": {}
}

Other vertical plugins (e.g. investment-banking, fund-admin, operations) already use the correct format and load fine — so the fix is just normalizing these 4 files.

Reproduction

claude plugin marketplace add anthropics/financial-services
claude plugin install financial-analysis@claude-for-financial-services
claude plugin list   # → financial-analysis: ✘ failed to load

Suggested fix

Replace contents of these files from [] to {"hooks": {}}:

• plugins/vertical-plugins/financial-analysis/hooks/hooks.json
• plugins/vertical-plugins/equity-research/hooks/hooks.json
• plugins/vertical-plugins/private-equity/hooks/hooks.json
• plugins/vertical-plugins/wealth-management/hooks/hooks.json

After applying the fix locally, all 17 plugins load successfully.

Environment

• Claude Code: 2.1.143
• OS: macOS (Darwin 24.6.0)
• Installed via claude plugin marketplace add anthropics/financial-services on 2026-05-17
