How to Use This Skill (Instructions for Claude)

CRITICAL: This skill is designed to be conversational and incremental. You must:

• ✅ Ask questions to understand the user's billing investigation goals
• ✅ Use MCP tools to retrieve actual data
• ✅ Analyze and interpret the billing data for the user
• ✅ Provide actionable insights about costs and trends
• ✅ Suggest optimizations when high costs are identified

DO NOT:

• ❌ Show all billing SKUs upfront unless asked
• ❌ Overwhelm with technical details before understanding the goal
• ❌ Provide generic advice without looking at actual usage data
• ❌ Continue analysis without user confirmation

Supporting Documentation:

• EXAMPLES.md: Detailed workflow examples with real data
• REFERENCE.md: Billing concepts, SKU catalog, optimization strategies

Conversation Flow Guide

Step 1: Identify Investigation Scope

ASK: "What would you like to investigate about your LimaCharlie billing?"

OPTIONS:

1. Analyze current costs for a specific organization
2. Compare billing across all my organizations
3. Investigate usage trends over time
4. Identify what's driving my costs (highest expenses)
5. Compare specific organizations against each other
6. Detect unusual usage or billing anomalies
7. Download invoices for accounting/finance
8. Understand a specific charge or SKU
9. Check payment method or subscription status
10. Something else / Not sure

WAIT for user response. DO NOT continue until they answer.

---

Step 2: Determine Organization Scope

Based on their response, ask:

IF they selected option 1 (specific org): "What's the Organization ID (OID) you'd like to analyze? You can find this in the LimaCharlie web UI under Organization Setup."

WAIT for OID.

IF they selected option 2 (all orgs): "I'll help you analyze all organizations you have access to. Let me get the list using the MCP server."

Use limacharlie:list_user_orgs to get all accessible organizations.

IF they selected option 5 (compare specific orgs): "Which organizations would you like to compare? Please provide the Organization IDs (OIDs) separated by commas."

WAIT for OIDs.

IF they selected option 7 (download invoices): "Which months and year do you need invoices for? (e.g., 'January 2025' or 'Q1 2025')"

Use limacharlie:get_org_invoice_url to generate download links.

IF they selected option 8 (understand charge/SKU): "What charge or SKU are you asking about? I can look it up in the SKU catalog."

Use limacharlie:get_sku_definitions to explain the SKU.

IF they selected option 9 (payment/subscription): "Let me check your billing details and subscription status..."

Use limacharlie:get_billing_details to show payment method and subscription info.

---

Step 3: Gather Billing Data

SAY: "Let me fetch the billing and usage data for [organization(s)]..."

Use MCP tools (with fully qualified names):

1. limacharlie:get_org_info - Organization details (name, tier, location, quota)
2. limacharlie:get_usage_stats - Current cycle usage statistics
3. limacharlie:get_billing_details - Stripe billing data (subscriptions, payments)
4. limacharlie:get_sku_definitions - SKU catalog (when explaining charges)
5. limacharlie:get_org_invoice_url - Invoice download links (when requested)
6. limacharlie:list_user_orgs - List accessible organizations

For each organization, retrieve:

• Organization name and ID
• Current billing cycle information
• Usage statistics by SKU
• Quota settings (if applicable)

---

Step 4: Analyze and Present Findings

Based on the data retrieved, analyze and present:

For Single Organization Analysis:

SAY: "Here's what I found for [Org Name] (OID: [OID]):"

Present in this structure:

1. Organization Overview

   • Org name and ID
   • Billing model (quota-based, usage-based, custom plan)
   • Current quota settings
   • Subscription status (if using limacharlie:get_billing_details)

2. Top Cost Drivers (sorted by highest to lowest)

   • Sensor costs (quota or usage-based)
   • Output data egress
   • Event storage
   • Query usage
   • Extensions
   • Artifacts
   • Payloads

3. Usage Highlights

   • Total sensors (online/quota)
   • Event volume processed
   • Event storage (retained data)
   • Output data transmitted
   • Notable extension usage

4. Observations

   • Flag any unusually high costs
   • Identify optimization opportunities
   • Compare against typical patterns
   • Reference EXAMPLES.md for detailed optimization workflows

ASK: "Would you like me to dig deeper into any of these areas, or suggest ways to optimize costs?"

For Multi-Organization Analysis:

SAY: "Here's a comparison across [N] organizations:"

Present as a table:

Organization	Sensors	Output Data	Event Volume	Top Cost Item	Estimated Monthly
Org A	50	25 GB	10M events	Sensors	$XXX
Org B	100	150 GB	45M events	Output data	$XXX
Org C	20	5 GB	2M events	Sensors	$XXX

Highlight:

• Highest cost organization
• Organizations with unusual patterns
• Opportunities for unified billing
• Cost optimization candidates

ASK: "Would you like me to investigate any specific organization in detail, or explore optimization strategies?"

Reference: See EXAMPLES.md for multi-org analysis examples.

---

Step 5: Deep Dive Analysis (If Requested)

When user wants deeper analysis, offer these options:

For Cost Drivers: "Let me break down [specific cost area] in detail..."

For Sensors:

• Quota utilization (current/max)
• Online vs offline sensors
• Sleeper mode candidates
• Sensor culling opportunities

Quota Utilization Interpretation: When analyzing quota utilization, interpret percentages as follows:

• < 50% utilization: ⚠️ WASTEFUL - User is paying for many unused sensors. Recommend reducing quota to match actual usage + 10-20% headroom for growth.

  • Example: 1 sensor using 15 quota = 7% utilization
  • Action: "You're paying for 14 unused sensors. Reduce quota to 2-3 sensors to save costs while maintaining headroom."

• 50-75% utilization: Low efficiency - Consider quota reduction to optimize costs.

  • Action: "Consider reducing quota to better match your actual deployment."

• 75-95% utilization: ✅ OPTIMAL - Good balance of usage and headroom. This is the ideal range.

  • Action: "Your quota utilization is well-optimized."

• 95-100% utilization: High utilization - Operating near capacity. Monitor for potential service issues.

  • Action: "Consider a small quota increase (5-10%) to provide headroom for spikes."

• > 100% utilization: ❌ SERVICE DEGRADATION - Sensors over quota will experience spotty/unreliable connectivity. This is NOT a billing issue (no overage charges), but a service reliability issue.

  • Action: "Increase quota to match your actual deployment OR cull inactive sensors to stay within quota."

For Output Data:

• Output destinations and volume per destination
• Stream types (event vs detection)
• Compression status
• Same-region GCP opportunities

For Event Storage:

• Retention period
• Event volume trends
• Insight extension status

For Queries:

• Query frequency
• Events evaluated
• Optimization opportunities

Reference: See REFERENCE.md for detailed cost optimization strategies.

---

Step 6: Trend Analysis (If Requested)

SAY: "Let me analyze usage trends over time..."

Note: The limacharlie:get_usage_stats tool provides current billing cycle data. For historical trends, guide the user to:

1. Usage Alerts Extension: "I recommend setting up the Usage Alerts extension to monitor ongoing usage and get alerts when thresholds are reached."

2. BigQuery Export: "For comprehensive historical analysis, you can export billing records to BigQuery and build custom reports with Looker Studio."

Reference: See REFERENCE.md section "Setting Up Cost Monitoring" for detailed setup instructions.

---

Step 7: Download Invoices (If Requested)

When user needs invoices:

1. Ask for time period: "Which months/year do you need?"
2. Use limacharlie:get_org_invoice_url for each month
3. Present download links in a clear format

Example:

Here are your invoice download links:
- January 2025: [Stripe invoice URL]
- February 2025: [Stripe invoice URL]
- March 2025: [Stripe invoice URL]

These links go directly to your Stripe invoices in PDF format.

Reference: See EXAMPLES.md "Workflow 6: Download invoices for finance team"

---

Step 8: Explain SKU or Charge (If Requested)

When user asks "What is [SKU name]?":

1. Use limacharlie:get_sku_definitions to fetch SKU catalog
2. Find the specific SKU they're asking about
3. Explain:
   • What the service does
   • How it's measured (unit type)
   • Pricing per unit
   • When you'd use it
4. Check current usage with limacharlie:get_usage_stats if applicable

Example:

"USP Telemetry Processed" ingests security telemetry from non-endpoint sources
like cloud logs and network devices. It's measured per GB processed at $15/GB.

Your current usage: 23GB this cycle (~$345)

Reference: See EXAMPLES.md "Workflow 7: What is this charge on my invoice?"

---

Step 9: Check Payment Method / Subscription (If Requested)

When user asks about payment method or subscription:

1. Use limacharlie:get_billing_details to fetch Stripe data
2. Extract relevant information:
   • Payment method (card type, last 4 digits, expiration)
   • Subscription status (active, cancelled, etc.)
   • Billing cycle dates
   • Customer information
3. Present clearly with appropriate masking for sensitive data

Example:

Payment method:
- Card: Visa ending in 9463
- Expires: 10/2027
- Status: Valid

Subscription:
- Status: Active
- Current cycle: Jan 3 - Feb 3, 2025
- Next invoice: Feb 3, 2025

Reference: See EXAMPLES.md "Workflow 8: What payment method am I using?"
