# Financial Analysis Skill

When performing financial analysis, follow these systematic steps to ensure thorough and accurate evaluation:

## Core Methodology

### 1. Data Collection and Verification
- Gather historical financial statements (income statement, balance sheet, cash flow)
- Verify data sources for accuracy and completeness
- Identify any anomalies or missing data points

### 2. Financial Ratio Analysis
Calculate and analyze key financial ratios:
- **Profitability**: EBITDA margin, net profit margin, ROE, ROA
- **Liquidity**: Current ratio, quick ratio, cash ratio
- **Leverage**: Debt-to-equity, interest coverage ratio
- **Efficiency**: Asset turnover, inventory turnover

### 3. Valuation Models
Build appropriate valuation models:
- **DCF Analysis**: Project free cash flows, determine WACC, calculate terminal value
- **Comparable Company Analysis**: Identify peers, analyze multiples (P/E, EV/EBITDA)
- **Precedent Transactions**: Review similar deals for valuation benchmarks

## Guidelines

- Always use conservative assumptions when uncertain
- Cross-validate findings with multiple valuation methods
- Clearly document all assumptions and their rationale
- Present results with appropriate caveats and risk factors

## Key Outputs

Your analysis should produce:
1. Executive summary of findings
2. Detailed financial model with assumptions
3. Valuation range with sensitivity analysis
4. Investment recommendation with risk assessment

from swarms import Agent

agent = Agent(
    agent_name="Financial-Analyst",
    model_name="claude-sonnet-4-6",
    skills_dir="./skills",  # Load all skills from directory
    max_loops=1,
)

# All skills are now available to the agent
response = agent.run("Perform a DCF valuation of Tesla")

from swarms import Agent

agent = Agent(
    agent_name="Versatile-Agent",
    model_name="claude-sonnet-4-6",
    skills_dir="./skills",
    max_loops=1,
)

# Only relevant skills are loaded based on the task
response = agent.run(
    "Analyze the financial statements and create a visualization of the revenue trends"
)
# Loads: financial-analysis and data-visualization skills

# Code Review Skill

When reviewing code, follow this systematic approach:

## Review Checklist

### 1. Security
- [ ] No hardcoded credentials or API keys
- [ ] Input validation for all user inputs
- [ ] Proper authentication and authorization
- [ ] SQL injection prevention
- [ ] XSS protection

### 2. Performance
- [ ] Efficient algorithms and data structures
- [ ] No unnecessary database queries
- [ ] Proper caching where appropriate
- [ ] Optimized loops and iterations

### 3. Code Quality
- [ ] Follows language conventions and style guide
- [ ] Clear and descriptive variable names
- [ ] Functions are single-purpose and small
- [ ] Proper error handling
- [ ] Adequate comments for complex logic

### 4. Testing
- [ ] Unit tests for all functions
- [ ] Edge cases covered
- [ ] Integration tests where needed
- [ ] Test coverage > 80%

## Review Format

Provide feedback in this structure:
1. Summary of findings (high-level overview)
2. Critical issues (must fix)
3. Important suggestions (should fix)
4. Minor improvements (nice to have)
5. Positive observations (what's done well)

## Communication Guidelines

- Be constructive and specific
- Provide examples and alternatives
- Explain the "why" behind suggestions
- Acknowledge good code when you see it

agent = Agent(
    agent_name="Code-Reviewer",
    model_name="claude-sonnet-4-6",
    skills_dir="./skills",
)

code = """
def login(username, password):
    query = f"SELECT * FROM users WHERE username='{username}' AND password='{password}'"
    return db.execute(query)
"""

review = agent.run(f"Review this code:\n{code}")
print(review)

# Data Visualization Skill

## Visualization Selection

### Choose the right chart type:
- **Comparison**: Bar charts, grouped bar charts
- **Trend over time**: Line charts, area charts
- **Distribution**: Histograms, box plots
- **Relationship**: Scatter plots, bubble charts
- **Composition**: Pie charts (use sparingly), stacked bar charts
- **Geographic**: Maps, choropleth maps

## Design Principles

1. **Clarity**: Make the message immediately clear
2. **Simplicity**: Remove chart junk and unnecessary elements
3. **Accuracy**: Don't mislead with scale or perspective
4. **Accessibility**: Use colorblind-friendly palettes

## Best Practices

- Start y-axis at zero for bar charts
- Use clear, descriptive labels
- Include data sources
- Provide context with annotations
- Choose appropriate color schemes
- Ensure text is readable

## Code Template

```python
import matplotlib.pyplot as plt
import seaborn as sns

# Set style
sns.set_style("whitegrid")
plt.figure(figsize=(12, 6))

# Create visualization
# ... your code ...

# Add labels and title
plt.xlabel("X Label", fontsize=12)
plt.ylabel("Y Label", fontsize=12)
plt.title("Descriptive Title", fontsize=14)

# Show plot
plt.tight_layout()
plt.show()

# Technical Writing Skill

## Documentation Structure

### 1. Introduction
- What is it?
- Why should I use it?
- Quick example

### 2. Getting Started
- Prerequisites
- Installation
- Basic setup
- "Hello World" example

### 3. Core Concepts
- Key terminology
- Architecture overview
- Main features

### 4. How-To Guides

## Skill Loading Internals

### How Skills are Loaded

```python
# Skills are loaded during agent initialization
agent = Agent(
    skills_dir="./skills",  # Path to skills directory
    model_name="claude-sonnet-4-6",
)

# Skills metadata is loaded from SKILL.md frontmatter
# Skills content is added to system prompt
# Agent can now use all skills

from swarms.structs.dynamic_skills_loader import DynamicSkillsLoader

# Manual skill loading
loader = DynamicSkillsLoader(skills_dir="./skills")

# Load skills relevant to a task
relevant_skills = loader.load_relevant_skills(
    "Perform financial analysis and create visualizations"
)

print(f"Loaded {len(relevant_skills)} relevant skills")
