Monte Carlo Asset Health Skill

This skill checks the health of a data asset using Monte Carlo's observability platform. It produces a structured health report covering freshness, alerts, monitoring coverage, importance, and upstream dependency health.

Monte Carlo tool routing (required): Always call Monte Carlo MCP tools through this plugin's bundled server, whose fully-qualified tool names are mcp__plugin_mc-agent-toolkit_monte-carlo-mcp__<tool> (e.g. mcp__plugin_mc-agent-toolkit_monte-carlo-mcp__get_alerts). Bare tool names used in this skill (get_alerts, search, get_table, …) refer to that bundled server. If the session also has a separately-configured monte-carlo-mcp server, do not route to it — it may point at a different endpoint or credentials.

REQUIRED: Read reference files before executing

You MUST read both reference files using the Read tool before making any MCP tool calls. These files are the source of truth for tool calls, parameters, and response interpretation. This file only defines when to activate and how to format the output.

1. references/workflows.md (relative to this file) — exact tool calls, phases, and execution order
2. references/parameters.md (relative to this file) — parameter conventions and field details

Do NOT make any MCP tool calls until you have read both files.

When to activate this skill

Activate when the user:

• Asks about health: "how is table X doing?", "check health of X", "is X healthy?"
• Asks about status: "what's the status of X?", "status of orders table"
• Asks to check on a table: "check on X table", "check on X"
• Asks about reliability, freshness, or quality of a specific asset
• References a table in context of incident triage or change planning

When NOT to activate this skill

• Profiling or exploring table data (row counts, column stats, distributions) → use explore-table
• Creating or suggesting monitors → use monitoring-advisor
• Active incident triage (investigating root cause of a firing alert) → use prevent skill Workflow 3

Health report format

CRITICAL: Only report data returned by the tools defined in references/workflows.md. Do NOT call additional tools, do NOT infer or fabricate metrics. Each row below specifies exactly which tool provides its value.

All sections (Active Alerts, Monitors, Upstream Issues, Recommendations) must always appear with their heading. Never omit a section — if there is no data, show the empty-state text defined below.

Never use emoji shortcodes (like :warning: or :arrow_up:). Use Unicode emoji characters directly (like ⚠️) or plain text. Shortcodes render as raw text in the terminal.

Always display URLs as bare URLs, never as markdown links (e.g., [text](url)).

{MC_WEBAPP_URL} appears throughout this template. Every occurrence must be replaced with the actual value returned by calling get_mc_webapp_url(). Never hardcode or guess this URL — it varies by environment.

Present results in this structure:

## Health Check: <table_name>

**Tags:** `tag1:value1`, `tag2:value2` (or "None" if no tags)
**Link:** {MC_WEBAPP_URL}/assets/{mcon}
**Warehouse:** snowflake-prod (Snowflake)
**Status: 🟢 Healthy / 🟡 Degraded / 🔴 Unhealthy** | **Importance:** 0.85 (key asset ⭐️)
**Avg Reads/Day:** ~538 | **Avg Writes/Day:** ~12

| Metric        | Value                          | Signal |
|---------------|--------------------------------|--------|
| Last Updated | Apr 6, 2025                    | 🟢 Recent    |
| Alerts        | 2 active                       | 🔴 Has alerts |
| Monitoring    | 3 active monitors              | 🟢 Monitored  |
| Upstream      | 1/3 sources unhealthy          | 🔴 Issues     |

### Active Alerts

| Date  | Type           | Priority | Status           | Link                                                    |
|-------|----------------|----------|------------------|---------------------------------------------------------|
| Apr 8 | Metric anomaly | P3       | Not acknowledged | {MC_WEBAPP_URL}/alerts/{alert_uuid} |
| Apr 7 | Freshness      | P2       | Acknowledged     | {MC_WEBAPP_URL}/alerts/{alert_uuid} |

If there are more than 5 active alerts, display only 5. Do NOT put the overflow
message inside the table as a row. Instead, put it as plain text on the line
immediately after the table:

There are N more alerts not shown for brevity

If there are zero active alerts, show:
No active alerts in the last 7 days.

### Monitors

| Type        | Name                                    | Incidents (7d) | Status              |
|-------------|-----------------------------------------|----------------|---------------------|
| TABLE       | Orders freshness and schema             | 3              | Running hourly      |
| METRIC      | Revenue row count                       | 0              | Never executed      |
| BULK_METRIC | Warehouse volume check                  | 21             | ⚠️ 1 table has errors |

If there are zero monitors, show:
No monitors configured for this table.

### Upstream Issues
- raw_orders — FRESHNESS alert: not updated in 8h
- raw_payments — healthy
- dim_customers — healthy

> Want me to check further upstream for **raw_orders**?

If there are no upstream dependencies, show:
No upstream dependencies found.

### Diagnosis

1-2 sentences summarizing what is causing the table to be unhealthy, or
confirming it is healthy. This should naturally lead into the recommendations.

Example (unhealthy):
Upstream table raw_orders has not been updated in 8 hours, which is likely
causing staleness in this table. There are also 2 unacknowledged alerts.

Example (healthy):
Table is healthy — no active alerts, monitored, and all upstream sources
are in good shape.

### Recommendations
- Investigate upstream raw_orders freshness — likely root cause of this table's staleness
- Acknowledge or investigate the 2 active alerts

If there are no recommendations, show:
No recommendations — table looks healthy.

Metric definitions — exact data sources

Each metric row MUST use only the specified data source. Do not add, infer, or embellish values beyond what the tool returns.

Metric	Data source	What to show	Signal
Last Updated	get_table → last_updated_on	Date of last data update (e.g., "Apr 6, 2025")	🟢 Recent (within 7 days) / 🟡 Stale (older than 7 days)
Alerts	get_alerts → count	"N active" or "No active alerts"	🔴 Has alerts / 🟢 No alerts
Monitoring	get_monitors → count where is_paused is false	"N active monitors" or "0 active monitors (M paused)". Include relevant details from monitor fields (incident counts, error counts, types).	🟢 Monitored (≥1 active) / 🔴 Unmonitored (0 active)
Upstream	get_asset_lineage (upstream) + Phase 3 checks	"N/M sources unhealthy" or "All N sources healthy"	🔴 Issues (any unhealthy) / 🟢 Healthy (all healthy)

Importance is shown next to the Status line (not in the metrics table). Source: get_table → importance_score + is_important. Show "X.XX (key asset ⭐️)" if key asset or importance > 0.8, otherwise just "X.XX".

Avg Reads/Day and Avg Writes/Day are shown below the Status line. Source: get_table → table_stats.avg_reads_per_active_day and table_stats.avg_writes_per_active_day.

Do NOT include downstream data. This skill only queries upstream lineage.

Status determination

• 🔴 Unhealthy: Any active alerts on the asset (from get_alerts with statuses ["NOT_ACKNOWLEDGED", "ACKNOWLEDGED", "WORK_IN_PROGRESS"] — see parameters.md)
• 🟡 Degraded: No active alerts, but 0 active monitors on a high-importance asset (importance > 0.8 or key asset)
• 🟢 Healthy: No active alerts and has at least 1 active monitor

Tags

Display tags from the search tool's properties field. Show as inline badges: key:value. If no tags exist, show "None". Always include the Tags line.

Warehouse

Display the warehouse name and type from the search result. Always include this line.

Recommendations

Only include recommendations derivable from collected data:

• Upstream health issues that may be root causes
• Active alerts that need acknowledgment or investigation
• Do NOT recommend specific monitor types — that is outside this skill's scope
