fix(plugins): hooks.json must be {"hooks": {}} not []; add plugin-validate CI
The empty-array hooks.json in private-equity, financial-analysis,
equity-research and wealth-management caused those plugins to fail to
load ("Hook load failed: expected object, received array"). Replace [] with
the minimal valid {"hooks": {}} object in all four.
Add a plugin-validate workflow that runs the official `claude plugin
validate` over the marketplace manifest and every plugin on each PR and
push, so a malformed manifest fails CI instead of reaching users. The
CLI is installed from the official binary channel and cached, keyed on a
pinned version, so a warm cache skips the download entirely.
- Move verticals from repo root into plugins/vertical-plugins/ and partner
plugins into plugins/partner-built/
- Add 10 named, self-contained agent plugins under plugins/agent-plugins/
(Pitch Agent, Market Researcher, Earnings Reviewer, Model Builder,
Meeting Prep, GL Reconciler, Month-End Closer, Statement Auditor,
Valuation Reviewer, KYC Screener) — each bundles its own skills so it
installs standalone
- Add managed-agent-cookbooks/ (one per agent) with subagent isolation
and steering examples for /v1/agents deployment
- Add fund-admin and operations verticals so the finance-ops/onboarding
agents ship real domain skills
- Add scripts/ (check.py manifest lint, sync-agent-skills.py,
deploy-managed-agent.sh, orchestrate.py reference loop,
test-cookbooks.sh)
- Add .github/workflows/secret-scan.yml (gitleaks + internal-ref grep)
- Tighten agent tool grants to declared MCPs only — no Bash, WebFetch,
or undeclared mcp__* references in any agent
- Add not-investment-advice disclaimer to README
- Rename claude-in-office to claude-for-msft-365-install (content
unchanged)
