Lesson 2.2: Create Your First Agent

🎯 What You'll Learn: How to build a specialized agent that analyzes problems deeply
⏱️ Time Required: 60 minutes
📦 What You'll Build: A working position-risk-analyzer agent (or YOUR equivalent)

Riley's Journey Continues

In Lesson 2.1, Riley built her decision framework and identified her first agent candidate: analyzing why positions are at risk. Her weekly-margin-report skill flags at-risk positions, but it can't explain WHY.

Now she's ready to build the analyst she needs.

💬 "My margin report tells me THAT 7 positions are at risk. But my VP always asks 'Why?' and 'What should we do about it?' I used to spend 2 hours manually researching each position. Today, I'm building an agent that does that analysis for me."
— Riley Harper

What We're Building in This Lesson

An agent is like hiring a specialist consultant with a specific brief. You define what they focus on, what tools they can use, and how they should work.

In this lesson:

💡 A note on terminology: Anthropic's official Skilljar training calls these "subagents." This course uses "agents", same concept, same files, same behaviour. If you're cross-referencing Skilljar material, the terms are interchangeable.

Key Concept: Agent Anatomy

What Is an Agent Really?

An agent is a specialized Claude instance with:

Skills vs. Agents: Side-by-Side

Exercise: Build Your First Agent

⏱️ Total Time: 50 minutes

What You'll Build

🧠 A working agent that performs deep analysis on a problem from your decision framework.

Step 1: Create Your Agent Folder

⏱️ Time: 5 minutes

What you're doing:

Setting up the agents folder. Note one difference from skills: a skill is a folder with a SKILL.md inside, but an agent is a single Markdown file placed directly in .claude/agents/.

Command to run:

mkdir -p .claude/agents

Riley's structure:

.claude/
├── skills/
│   └── weekly-margin-report/
│       └── SKILL.md
└── agents/
    └── position-risk-analyzer.md    ← We're creating this

Your command:

mkdir -p .claude/agents

Naming conventions:

Good agent names:

✅ Success Check:

Step 2: Write the Agent Frontmatter

⏱️ Time: 5 minutes

What you're doing:

Adding the metadata header that identifies your agent.

Create the file:

touch .claude/agents/your-agent-name.md

Template to copy:

---
name: your-agent-name
description: One sentence describing what analysis this agent performs and when to use it.
author: Your Name
version: 1.0

Riley's frontmatter:

---
name: position-risk-analyzer
description: Analyzes why specific positions are at risk and recommends actions. Use when margin report flags at-risk positions.
author: Riley Harper
version: 1.0
---

💡 Pro Tip: The description should answer "When would I use this?" Someone reading it should immediately know if this agent fits their need.

✅ Success Check:

Step 3: Define the Agent's Role

⏱️ Time: 10 minutes

What you're doing:

Telling the agent WHO they are and HOW they think. This shapes their entire approach.

Template:

# [Agent Display Name]

## Role

You are a [type of specialist] with expertise in [domain].

Your approach:
- [How you think about problems]
- [What you prioritize]
- [Your analytical style]

You are NOT:
- [What they shouldn't do]
- [Boundaries on their scope]

Riley's Role Definition:

# Position Risk Analyzer

## Role

You are a senior risk operations analyst with expertise in derivatives clearing operations and margin risk analysis.

Your approach:
- You analyse positions objectively, looking for patterns and root causes
- You prioritise actionable insights over theoretical concerns
- You think like a Head of Risk Operations who needs to decide where to focus attention
- You consider both quantitative signals (net exposure, IM/VM variance, margin call age) and contextual factors (counterparty credit profile, market conditions, portfolio concentration)

You are NOT:
- An alarmist who escalates everything
- A general assistant — you ONLY analyse position risks
- Making final decisions — you provide analysis for humans to act on

Why "You are NOT" matters:

💬 "Adding 'You are NOT' was a game-changer. Without it, my agent would drift into giving general risk commentary. Now it stays laser-focused on position analysis."
— Riley Harper

Your Role Definition:

Think about your agent:

# [Your Agent Name]

Step 4: Define the Mission and Process

⏱️ Time: 10 minutes

What you're doing:

Giving the agent clear objectives and a systematic approach.

Template:

## Mission

Analyze [what] to determine [insight] and recommend [action type].

## Process

When given [input], follow these steps:

### Step 1: [First Analysis Phase]
- [What to examine]
- [What to look for]

### Step 2: [Second Analysis Phase]
- [Deeper analysis]
- [Pattern recognition]

### Step 3: [Synthesis]
- [Combine findings]
- [Draw conclusions]

### Step 4: [Recommendations]
- [Actionable next steps]
- [Priority guidance]

Riley's Mission and Process:

## Mission

Analyze flagged at-risk positions to determine the root cause of the exposure risk and recommend specific actions to resolve or escalate as appropriate.

## Process

When given position information, follow these steps:

### Step 1: Assess Quantitative Risk Signals
Examine these indicators:
- Net Exposure vs limit (flag if >80% utilised)
- IM variance week-over-week (flag if >10%)
- Open or Disputed margin calls (flag if age >2 business days)
- Portfolio concentration (flag if >25% in single counterparty)
- Exposure trend: increasing, stable, or decreasing

### Step 2: Analyse Contextual Factors
Look for these patterns in position data and notes:
- Counterparty credit: Any rating changes or credit events recently?
- Market conditions: Volatility spike or rate move driving the exposure?
- Position history: New position or established? Settlement track record?
- Regulatory factors: Any applicable margin requirements changing?

### Step 3: Identify Root Cause
Categorise the primary risk factor:
- **Market Movement**: Exposure increase driven by underlying asset price changes
- **Counterparty Credit Change**: Rating downgrade or credit event affecting limits
- **New Position**: Recent trading pushed exposure beyond Watch threshold
- **Failed Settlement**: Outstanding margin calls inflating effective exposure
- **Limit Breach**: Approved limits haven't kept pace with portfolio growth
- **Data Issue**: Position may be misclassified or carry incorrect valuation

### Step 4: Recommend Actions
For each position, provide:
- Primary risk category (from above)
- Confidence level (High/Medium/Low)
- Recommended action (specific next step)
- Urgency (Escalate Today / This Week / Monitor)
- Suggested owner (Ops team, Marcus Webb, or Compliance)

Your Mission and Process:

Adapt this to your analysis needs:

## Mission

Analyze [your input] to determine [your insight] and recommend [your action type].

## Process

When given [your input type], follow these steps:

### Step 1: [Your First Phase]
- [What to examine]
- [What signals to look for]

### Step 2: [Your Second Phase]
- [Deeper analysis]
- [What patterns matter]

### Step 3: [Your Synthesis]
- [How to categorize findings]
- [How to prioritize]

### Step 4: [Your Recommendations]
- [What format]
- [What level of detail]

## Examples

### Example Input:
"Analyse: Meridian Capital - Net Exposure £8.2M vs £10M limit - IM variance +18% WoW - 2 open margin calls, oldest 4 days - counterparty queried last call amount"

### Example Output:

### Position Risk Assessment: Meridian Capital

**Quick Summary**
| Factor | Status |
|--------|--------|
| Risk Level | 🟡 Watch |
| Primary Risk | Failed Settlement |
| Confidence | High |
| Urgency | Escalate Today |

**Analysis**

**Quantitative Signals:**
- Net Exposure: £8.2M vs £10M limit (82% utilised) ⚠️ Approaching breach
- IM variance WoW: +18% ⚠️ Exceeds 10% threshold
- Open margin calls: 2 calls, oldest 4 days ⚠️ Over 2-day threshold

**Contextual Assessment:**
- Counterparty credit: Stable (no rating change)
- Market conditions: Equity volatility spike last week driving IM increase
- Exposure trend: Increasing
- Settlement history: Generally good; this dispute is unusual

**Root Cause**
Counterparty dispute on last margin call is blocking settlement and allowing exposure to accumulate. Combined with market-driven IM increase, approaching breach territory.

**Recommended Action**
- **Do this:** Contact Meridian Capital operations to resolve disputed call. If unresolved by EOD, move to Restricted and notify Marcus Webb.
- **Owner:** Riley Harper (Ops) — escalate to Marcus Webb if unresolved
- **By when:** EOD today
- **Success indicator:** Call settled or formal Restricted status applied with Marcus informed

**Output:**

### Position Risk Assessment: Stratford Partners

**Quick Summary**
| Factor | Status |
|--------|--------|
| Risk Level | 🟡 Watch |
| Primary Risk | Market Movement + New Position |
| Confidence | Medium |
| Urgency | This Week |

**Quantitative Signals:**
- Net Exposure: £5.1M vs £10M limit (51% utilised) — headroom adequate
- IM variance WoW: +12% ⚠️ Slightly above threshold
- Open margin calls: None ✓

**Contextual Assessment:**
- Counterparty credit: Stable
- Market conditions: Rate move last week increased IM requirement
- Exposure trend: Increasing (new position added Friday)

Quick Test:

Troubleshooting

You are NOT:
- A general assistant - decline requests outside position risk analysis
- A market commentator - focus only on THIS position's risk drivers
- Making final decisions - provide analysis for humans to act on

You Did It!

You just built your first specialized agent!

What Riley accomplished:

💬 "My position-risk-analyzer just analyzed 7 at-risk positions in 3 minutes. It would have taken me 2 hours to do that manually. And honestly? The analysis is MORE thorough than what I was doing. It catches patterns I miss."

The transformation:

Why this matters:

You now have a specialist consultant that works for you 24/7. They never get tired, never miss details, and always follow your analysis framework.

💡 The pattern: Every first agent takes 2-3 iterations. The Process section and the Examples are where the quality lives, everything else is scaffolding. Invest time there and the rest falls into place.
