Monte Carlo Root Cause Analysis Skill

This skill helps investigate data incidents — freshness delays, volume anomalies, schema changes, field metric drift, and ETL failures — by guiding the agent through a systematic investigation using Monte Carlo's MCP tools. It combines observability metadata with optional direct data querying to find the root cause.

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.

Reference files live next to this skill file. Use the Read tool (not MCP resources) to access them:

Investigation playbooks by issue type: references/<type>-investigation.md
Data exploration patterns: references/data-exploration.md
Intake when no incident ID: references/intake-no-incident.md
Common root cause catalog: references/common-root-causes.md

When to activate this skill

Activate when the user:

Mentions a Monte Carlo alert, incident, or anomaly
Asks "why is this table stale?" or "why did row count drop?"
Wants to investigate a data quality issue
Asks about freshness, volume, or schema problems
Mentions pipeline failures (Airflow, dbt, Databricks)
Says things like "debug this alert", "investigate this incident", "root cause analysis"

When NOT to activate this skill

Do not activate when the user is:

Creating monitors (use the monitoring-advisor skill)
Investigating agent-monitor alerts (agent evaluation, agent metric, agent trajectory, agent validation) or AI-agent traces/conversations (use the monte-carlo-troubleshoot-agent-traces skill — read ../troubleshoot-agent-traces/SKILL.md)
Running impact assessments before code changes (use the prevent skill)
Looking at storage costs (use the storage-cost-analysis skill)
Exploring pipeline performance without a specific incident (use the performance-diagnosis skill)

Prerequisites

Required: Monte Carlo MCP server (integrations.getmontecarlo.com/mcp) must be configured and authenticated.

Optional but recommended:

Database MCP server (Snowflake, BigQuery, Redshift, Databricks) — enables direct SQL queries for deeper data investigation. Without this, the skill can still analyze using MC's metadata tools but cannot profile actual data.
GitHub MCP server — enables searching for recent PRs that may have caused the issue. Without this, the skill falls back to MC's query change detection.

MCP Tools Used

From Monte Carlo MCP server

Tool	Purpose
`get_alerts`	Fetch incident/alert details
`search`	Find tables by name or keyword
`get_table`	Table metadata and fields
`get_asset_lineage`	Table-level upstream/downstream lineage
`get_field_lineage`	Field-level lineage (trace bad data to source column)
`get_table_freshness`	Table update/freshness history
`get_table_size_history`	Row count and size history
`get_queries_for_table`	Read/write query history
`get_query_changes`	Detect SQL text modifications
`get_query_rca`	Root cause analysis for failed/futile/missed queries
`get_etl_issues`	ETL pipeline issues — pass `platform` ("airflow", "dbt", or "databricks")
`get_etl_jobs`	Find ETL jobs that write to specific tables — pass `platform` param
`get_github_prs`	Recent GitHub PRs from the account's MC GitHub integration
`get_jobs_performance`	Job runtime stats, failure rates, 7-day trends
`get_change_timeline`	Unified timeline: query changes + volume + ETL failures
`alert_assessment`	Optional ~2-min triage of an incident — returns HIGH/MEDIUM/LOW confidence and impact. Useful when you want a quick read before deciding to escalate to TSA.
`run_troubleshooting_agent`	Starts the Troubleshooting Agent (TSA) on an incident. Async by default; idempotent (returns existing results unless `force_rerun=True`). Auto-invoked at Step 1.5 when an incident UUID is present.
`get_troubleshooting_agent_results`	Polls TSA results for an incident (`status` is `not_found` / `running` / `success` / `failed`). Use to check on the async run started at Step 1.5.

Credits: alert_assessment and run_troubleshooting_agent consume Monte Carlo credits the same way the Troubleshooting Agent does when launched from the Monte Carlo UI. Each fresh run_troubleshooting_agent call is a billable run; reuse via the built-in idempotency (don't pass force_rerun=True unless the user explicitly asks for a fresh analysis).

Optional external MCP tools

Tool	Purpose
Database MCP (Snowflake, BigQuery, etc.)	Run SQL queries for data profiling
GitHub MCP	Search for recent PRs (alternative to MC's `get_github_prs` — useful if the account has no MC GitHub integration)

Workflow

Step 1: Understand the problem (intake)

If the user provides an alert or incident ID:

Call get_alerts with the alert ID to fetch details.
Identify: affected table(s), issue type (freshness, volume, schema, field metric), when it started.
Proceed to Step 2.

If the user describes a problem WITHOUT an incident ID: Read references/intake-no-incident.md for the full intake flow. In short:

Ask clarifying questions: what table? what looks wrong? when did it start?
Search for the table: search(query="table_name")
Search for related alerts: get_alerts with a recent time range. Pass ISO 8601 timestamps computed from the current date — e.g. created_after="2026-07-03T00:00:00Z", created_before="2026-07-10T00:00:00Z" for a 7-day window (use the actual current date).
Check table health: get_table_freshness, get_table_size_history
Narrow down the issue type and proceed to Step 2.

Step 1.5: Auto-invoke TSA (when applicable)

When intake produces a Monte Carlo incident UUID, kick off the Troubleshooting Agent (TSA) before continuing to Step 2. TSA runs the same root-cause analysis the Monte Carlo UI uses; running it here in parallel with the manual investigation usually beats running either path alone.

Skip TSA when any of these is true:

No incident UUID. run_troubleshooting_agent requires a UUID. The no-incident intake path (references/intake-no-incident.md) does not feed TSA. If that path later identifies a matching alert, return to Step 1 with the alert's incident UUID — Step 1.5 then applies normally.
Narrow scoped check. The user wants a single fact, not an investigation. Examples: "is analytics.orders stale right now?", "what's the row count of X?", "show me the schema of Y", "did this query run today?". Answer the question with the relevant tool and stop. TSA is overkill for these.
Explicit user opt-out. The user says "skip TSA", "don't run TSA", "manual only", "just do it yourself", or similar. Honor the opt-out and proceed to Step 2 without invoking TSA.

Default invocation (async, parallel):

run_troubleshooting_agent(incident_id="<uuid>", async_mode=True)

The tool is idempotent by default: if a previous successful TSA run exists for this incident, it returns those results immediately. Do not pass force_rerun=True unless the user explicitly asks for a fresh analysis (each fresh run is a billable Monte Carlo credit consumption).
If status is success on the first call, you have results — fold them straight into Step 7's synthesis and continue Steps 2–6 to corroborate.
If status is queued or running, continue to Step 2 immediately. TSA typically completes in 4–8 minutes; you'll poll for results via get_troubleshooting_agent_results later in the flow (see Step 4 and Step 7).
If status is failed, note the error and continue with the manual investigation only — do not re-run automatically.

Tell the user what you started: "I've kicked off the Troubleshooting Agent on this incident — it usually finishes in 4–8 minutes. While it runs, I'll continue investigating manually so we have findings either way."

Step 2: Map the blast radius

TSA in parallel: if you started TSA at Step 1.5, it is running in the background while you do this step. Do not block on it.

Call get_asset_lineage(mcons=[table_mcon], direction="UPSTREAM") — what feeds this table?
Call get_asset_lineage(mcons=[table_mcon], direction="DOWNSTREAM") — what does this table feed?
If the issue involves specific fields, call get_field_lineage to trace which upstream fields feed the affected columns.

Report to the user: "This table is fed by X upstream sources and feeds Y downstream consumers. Here's what could be impacted."

Ask for direction: Before diving deeper, ask the user what they'd like to investigate first. They may already have a hunch ("I think it's the Airflow job" or "check if someone changed the SQL"). Follow their lead — don't run all investigation paths blindly. If they have no preference, proceed with the most likely path based on the issue type.

Step 3: Investigate based on issue type

Read the appropriate reference file and follow its investigation playbook:

Issue Type	Reference
Table not updating on schedule	`references/freshness-investigation.md`
Unexpected row count changes	`references/volume-investigation.md`
Columns added, removed, or type-changed	`references/schema-investigation.md`
Airflow/dbt/Databricks pipeline failures	`references/etl-failure-investigation.md`
SQL modifications causing data changes	`references/query-change-investigation.md`
Field-level metric drift (null rate, mean, etc.)	`references/field-anomaly-investigation.md`
Agent-monitor alert (agent evaluation, metric, trajectory, or validation)	Hand off — read and follow `../troubleshoot-agent-traces/SKILL.md` instead of continuing here

Step 4: Check for upstream causes

Data issues often originate upstream. Walk the lineage chain:

For each direct upstream table from Step 2:
- Check freshness: get_table_freshness — is the upstream table also stale?
- Check size: get_table_size_history — did the upstream table's volume change?
- Check ETL status: get_etl_issues with the relevant platform
Use get_field_lineage to trace the specific field that has bad data back to its source.
Check what upstream field values correlate with the anomaly (if DB connector is available — see Step 5).

TSA poll #1. If you started TSA at Step 1.5 and it has not yet returned success, call get_troubleshooting_agent_results(incident_id=...) once here (~30s after Step 1.5). If status is success, hold the result for Step 7. If still running, keep going — you'll poll again before Step 7. Don't block on it.

Step 5: Profile data (if database MCP is available)

If the user has a database MCP server connected (Snowflake, BigQuery, Redshift, Databricks, etc.), read references/data-exploration.md for SQL investigation patterns including:

Sample rows around the incident time
Null rate and distribution checks
Value correlation with upstream tables
Before/after comparisons

If no database MCP is available: Tell the user: "I can'

## Workflow

### Step 1: Understand the problem (intake)

**If the user provides an alert or incident ID:**
1. Call `get_alerts` with the alert ID to fetch details.
2. Identify: affected table(s), issue type (freshness, volume, schema, field metric), when it started.
3. Proceed to Step 2.

**If the user describes a problem WITHOUT an incident ID:**
Read `references/intake-no-incident.md` for the full intake flow. In short:
1. Ask clarifying questions: what table? what looks wrong? when did it start?
2. Search for the table: `search(query="table_name")`
3. Search for related alerts: `get_alerts` with a recent time range. Pass ISO 8601
   timestamps computed from the current date — e.g. `created_after="2026-07-03T00:00:00Z"`,
   `created_before="2026-07-10T00:00:00Z"` for a 7-day window (use the actual current date).
4. Check table health: `get_table_freshness`, `get_table_size_history`
5. Narrow down the issue type and proceed to Step 2.

### Step 1.5: Auto-invoke TSA (when applicable)

When intake produces a Monte Carlo **incident UUID**, kick off the Troubleshooting Agent (TSA) **before** continuing to Step 2. TSA runs the same root-cause analysis the Monte Carlo UI uses; running it here in parallel with the manual investigation usually beats running either path alone.

**Skip TSA when any of these is true:**

1. **No incident UUID.** `run_troubleshooting_agent` requires a UUID. The no-incident intake path (`references/intake-no-incident.md`) does not feed TSA. If that path later identifies a matching alert, return to Step 1 with the alert's incident UUID — Step 1.5 then applies normally.
2. **Narrow scoped check.** The user wants a single fact, not an investigation. Examples: "is `analytics.orders` stale right now?", "what's the row count of X?", "show me the schema of Y", "did this query run today?". Answer the question with the relevant tool and stop. TSA is overkill for these.
3. **Explicit user opt-out.** The user says "skip TSA", "don't run TSA", "manual only", "just do it yourself", or similar. Honor the opt-out and proceed to Step 2 without invoking TSA.

**Default invocation (async, parallel):**

```
run_troubleshooting_agent(incident_id="<uuid>", async_mode=True)
```

- The tool is **idempotent** by default: if a previous successful TSA run exists for this incident, it returns those results immediately. Do **not** pass `force_rerun=True` unless the user explicitly asks for a fresh analysis (each fresh run is a billable Monte Carlo credit consumption).
- If status is `success` on the first call, you have results — fold them straight into Step 7's synthesis and continue Steps 2–6 to corroborate.
- If status is `queued` or `running`, continue to Step 2 immediately. TSA typically completes in 4–8 minutes; you'll poll for results via `get_troubleshooting_agent_results` later in the flow (see Step 4 and Step 7).
- If status is `failed`, note the error and continue with the manual investigation only — do not re-run automatically.

Tell the user what you started: "I've kicked off the Troubleshooting Agent on this incident — it usually finishes in 4–8 minutes. While it runs, I'll continue investigating manually so we have findings either way."

### Step 2: Map the blast radius

> **TSA in parallel:** if you started TSA at Step 1.5, it is running in the background while you do this step. Do not block on it.

1. Call `get_asset_lineage(mcons=[table_mcon], direction="UPSTREAM")` — what feeds this table?
2. Call `get_asset_lineage(mcons=[table_mcon], direction="DOWNSTREAM")` — what does this table feed?
3. If the issue involves specific fields, call `get_field_lineage` to trace which upstream fields feed the affected columns.

Report to the user: "This table is fed by X upstream sources and feeds Y downstream consumers. Here's what could be impacted."

**Ask for direction:** Before diving deeper, ask the user what they'd like to investigate first. They may already have a hunch ("I think it's the Airflow job" or "check if someone changed the SQL"). Follow their lead — don't run all investigation paths blindly. If they have no preference, proceed with the most likely path based on the issue type.

### Step 3: Investigate based on issue type

Read the appropriate reference file and follow its investigation playbook:

| Issue Type | Reference |
|-----------|-----------|
| Table not updating on schedule | `references/freshness-investigation.md` |
| Unexpected row count changes | `references/volume-investigation.md` |
| Columns added, removed, or type-changed | `references/schema-investigation.md` |
| Airflow/dbt/Databricks pipeline failures | `references/etl-failure-investigation.md` |
| SQL modifications causing data changes | `references/query-change-investigation.md` |
| Field-level metric drift (null rate, mean, etc.) | `references/field-anomaly-investigation.md` |
| Agent-monitor alert (agent evaluation, metric, trajectory, or validation) | Hand off — read and follow `../troubleshoot-agent-traces/SKILL.md` instead of continuing here |

### Step 4: Check for upstream causes

Data issues often originate upstream. Walk the lineage chain:

1. For each direct upstream table from Step 2:
   - Check freshness: `get_table_freshness` — is the upstream table also stale?
   - Check size: `get_table_size_history` — did the upstream table's volume change?
   - Check ETL status: `get_etl_issues` with the relevant `platform`
2. Use `get_field_lineage` to trace the specific field that has bad data back to its source.
3. Check what upstream field values correlate with the anomaly (if DB connector is available — see Step 5).

**TSA poll #1.** If you started TSA at Step 1.5 and it has not yet returned `success`, call `get_troubleshooting_agent_results(incident_id=...)` once here (~30s after Step 1.5). If status is `success`, hold the result for Step 7. If still `running`, keep going — you'll poll again before Step 7. Don't block on it.

### Step 5: Profile data (if database MCP is available)

If the user has a database MCP server connected (Snowflake, BigQuery, Redshift, Databricks, etc.), read `references/data-exploration.md` for SQL investigation patterns including:
- Sample rows around the incident time
- Null rate and distribution checks
- Value correlation with upstream tables
- Before/after comparisons

**If no database MCP is available:** Tell the user: "I can'
