## Mission

Verify the entire CRE Acquisition Orchestration System is operational before running a deal. Check that all required files exist, configs are valid JSON, the agent registry is complete and all agent files are present, the dashboard can start, and data directories are writable. Produce a comprehensive health report so the operator knows whether the system is ready.

## Strategy

### Step 1: File Existence Check -- Orchestrator Files

Verify all 6 orchestrator markdown files exist:

| File | Path |
|------|------|
| Master Orchestrator | `orchestrators/master-orchestrator.md` |
| Due Diligence Orchestrator | `orchestrators/due-diligence-orchestrator.md` |
| Underwriting Orchestrator | `orchestrators/underwriting-orchestrator.md` |
| Financing Orchestrator | `orchestrators/financing-orchestrator.md` |
| Legal Orchestrator | `orchestrators/legal-orchestrator.md` |
| Closing Orchestrator | `orchestrators/closing-orchestrator.md` |

For each file: Read it. If the read succeeds, mark PASS. If it fails, mark FAIL.

### Step 2: Agent Registry Check

- Read `config/agent-registry.json`
- Verify it is valid JSON
- Verify it contains all 21 agent entries
- For each agent entry:
  - Extract the file path
  - Read the agent file to confirm it exists
  - Verify the file contains required sections: `Identity`, `Mission`, `Strategy`, `Output`
- Report: total agents in registry, agents with valid files, agents with missing/incomplete files

Expected agents (21 total):

| Phase | Agents |
|-------|--------|
| Due Diligence (7) | rent-roll-analyst, opex-analyst, physical-inspection, legal-title-review, market-study, tenant-credit, environmental-review |
| Underwriting (3) | financial-model-builder, scenario-analyst, ic-memo-writer |
| Financing (3) | lender-outreach, quote-comparator, term-sheet-builder |
| Legal (6) | psa-reviewer, loan-doc-reviewer, title-survey-reviewer, estoppel-tracker, insurance-coordinator, transfer-doc-preparer |
| Closing (2) | closing-coordinator, funds-flow-manager |

### Step 3: Config Validation

Validate each configuration file:

| Config File | Checks | Error Level if Missing |
|------------|--------|----------------------|
| `config/deal.json` | Valid JSON? Required top-level keys present? | WARN (may not exist until deal is configured) |
| `config/thresholds.json` | Valid JSON? Has all 5 phase sections (dueDiligence, underwriting, financing, legal, closing)? | FAIL |
| `config/agent-registry.json` | Valid JSON? Has 21 entries? | FAIL |
| `config/deal-schema.json` | Valid JSON? Has properties definition? | WARN |

### Step 4: Skill Files Check

Verify all skill markdown files exist under `skills/`:

| Skill File | Path |
|-----------|------|
| Underwriting Calculations | `skills/underwriting-calc.md` |
| Multifamily Benchmarks | `skills/multifamily-benchmarks.md` |
| Risk Scoring | `skills/risk-scoring.md` |
| Self-Review Protocol | `skills/self-review-protocol.md` |
| Legal Checklist | `skills/legal-checklist.md` |
| Market Research | `skills/market-research.md` |
| Lender Database | `skills/lender-database.md` |
| Report Writing | `skills/report-writing.md` |

Use Glob to find all `.md` files under `skills/` and cross-reference against the expected list. Mark FAIL for any missing file, PASS for each present file.

### Step 5: Template Files Check

Verify the `templates/` directory has required template files:

| Template | Path |
|----------|------|
| Report Template | `templates/report-template.md` |
| IC Memo Template | `templates/ic-memo-template.md` |

Use Glob to list all files under `templates/` and verify the expected templates are present. Mark WARN for any missing template.

### Step 6: Directory Structure Check

Verify the data output directories exist or can be created:

| Directory | Purpose | Error Level if Missing |
|-----------|---------|----------------------|
| `data/status/` | Master and agent checkpoint files | FAIL |
| `data/logs/` | Phase and agent log files | FAIL |
| `data/reports/` | Generated reports and memos | FAIL |

For each directory:
- Use Bash to check if the directory exists
- If it does not exist, attempt to create it
- If creation succeeds, mark WARN (created during health check)
- If creation fails, mark FAIL

### Step 7: Dashboard Check

Verify the dashboard application is ready:

| Check | Method | Error Level if Failing |
|-------|--------|----------------------|
| `dashboard/package.json` exists | Read the file | FAIL |
| `package.json` is valid JSON | Parse check | FAIL |
| `node_modules/` directory exists | Bash `ls` check | WARN (advise: run `npm install`) |
| Dev script defined | `scripts.dev` key exists in package.json | WARN |

### Step 8: Validation Files Check

Verify the validation suite is complete:

| Check | Path | Error Level |
|-------|------|-------------|
| Test deal data | `validation/test-deal.json` | WARN |
| Expected outputs directory | `validation/expected-outputs/` | WARN |
| DD expected output | `validation/expected-outputs/dd-summary.json` | WARN |
| UW expected output | `validation/expected-outputs/uw-summary.json` | WARN |
| Financing expected output | `validation/expected-outputs/financing-summary.json` | WARN |
| Legal expected output | `validation/expected-outputs/legal-summary.json` | WARN |
| Closing expected output | `validation/expected-outputs/closing-summary.json` | WARN |
| Validation runner | `validation/validation-runner.md` | WARN |

### Step 9: Script Files Check

Verify all utility scripts exist:

| Script | Path | Error Level |
|--------|------|-------------|
| Launch script | `scripts/launch.sh` or `scripts/launch.ps1` | WARN |
| Resume script | `scripts/resume.sh` or `scripts/resume.ps1` | WARN |
| Health check script | `scripts/health-check.sh` or `scripts/health-check.ps1` | WARN |
| Validate script | `scripts/validate.sh` or `scripts/validate.ps1` | WARN |
| Reset script | `scripts/reset.sh` or `scripts/reset.ps1` | WARN |

Use Glob to find all files under `scripts/` and cross-reference. Mark WARN for missing scripts (they are convenience wrappers, not required for core operation).

### Step 10: Generate Health Report

Compile all check results into the structured output. Determine overall status:

| Status | Criteria |
|--------|----------|
| **HEALTHY** | All checks PASS (zero FAILs, zero WARNs) |
| **DEGRADED** | Some WARNs but zero FAILs |
| **UNHEALTHY** | One or more FAILs |

---

## Output Format

```json
{
  "agent": "health-check",
  "timestamp": "{ISO-8601 timestamp}",
  "overallStatus": "HEALTHY | DEGRADED | UNHEALTHY",

  "summary": {
    "totalChecks": 0,
    "passed": 0,
    "failed": 0,
    "warnings": 0
  },

  "checks": [
    {
      "checkName": "{descriptive name of the check}",
      "category": "orchestrators | agents | configs | skills | templates | directories | dashboard | validation | scripts",
      "status": "PASS | FAIL | WARN",
      "message": "{human-readable result description}",
      "details": "{additional context, file path, or error message}"
    }
  ],

  "recommendations": [
    "{actionable recommendation for any FAIL or WARN items}"
  ]
}
```

---

## Status Determination

| Overall Status | Rule |
|---------------|------|
| **HEALTHY** | Every check has status PASS |
| **DEGRADED** | At least one WARN, zero FAILs -- system can run but may have issues |
| **UNHEALTHY** | At least one FAIL -- system should not run until issues are resolved |

---

## Output Location

| Output | Path | Format |
|--------|------|--------|
| Health Report | stdout (returned to caller) | JSON |
| Log File | `data/logs/health-check.log` | Text, append-only |

---

## Logging Protocol

All log entries follow this format:

```
[{ISO-timestamp}] [health-check] [{level}] {message}
```

Levels: `INFO`, `WARN`, `ERROR`

Log events:
- Agent start
- Each check category begin/complete with counts
- Each FAIL or WARN item (individual log entry)
- Overall status determination
- Agent completion with summary

---

## Error Recovery

| Error Type | Action | Max Retries |
|-----------|--------|-------------|
| Cannot read any file | Log the specific file as FAIL, continue checking others | 0 |
| Cannot create directory | Log as FAIL, continue checking others | 1 |
| agent-registry.json missing | Mark as FAIL, skip agent file checks, continue with other categories | 0 |
| Bash command fails | Log as WARN, continue with remaining checks | 0 |

The health check agent should never halt entirely. It completes all checks it can and reports the aggregate result. Individual failures are captured in the checks array.

---

## Usage

This agent is typically run:
1. Before the first deal pipeline launch (initial system verification)
2. After pulling updates to the codebase (regression check)
3. When troubleshooting pipeline failures (diagnostic tool)
4. As part of the validation suite (`validation/validation-runner.md` Level 1)

Invocation:
```
Read validation/health-check.md → launch as Task agent
```
