Agentic AI Prompt Research

Skill by ara.so — AI Agent Skills collection.

This project documents reconstructed prompt patterns and architectural designs from modern agentic AI coding assistants. It provides educational insights into how systems like Claude Code assemble dynamic prompts, coordinate multiple agents, manage security, and handle context windows.

What This Project Provides

A collection of 30+ documented patterns covering:

• Core Identity: Main system prompts, simple mode, default agent instructions, security boundaries
• Orchestration: Coordinator prompts, multi-agent communication protocols
• Specialized Agents: Verification, exploration, agent creation, configuration agents
• Security: Permission explainers, auto-approval classifiers, risk assessment
• Context Management: Conversation compaction, memory selection, session search
• Skills: Reusable multi-agent workflows (simplify, skillify, stuck, remember)

All patterns are based on behavioral observation and reverse engineering, not leaked proprietary code.

Key Architectural Patterns

1. Dynamic Prompt Assembly

The system assembles prompts from modular components:

┌─────────────────────────────────────┐
│   Cacheable Prefix (stable)         │
│   - Identity & safety rules         │
│   - Permission configuration        │
│   - Code style preferences          │
│   - Tool usage patterns             │
├─────────────────────────────────────┤  ← Cache boundary
│   Dynamic Suffix (per-session)      │
│   - Available agents/skills         │
│   - Memory file contents            │
│   - Environment context             │
│   - Active MCP servers              │
└─────────────────────────────────────┘

Example pattern from 01_main_system_prompt.md:

# Core identity established first
You are Claude Code, an agentic AI coding assistant...

# Tool preferences defined
When editing files, prefer multi_file_edit for batching...

# Security boundaries set
Never execute commands that could compromise user data...

# Dynamic sections injected
[AVAILABLE_AGENTS: verification, explore, statusline_setup]
[MEMORY_FILES: .claude/project_rules.md, .claude/preferences.md]
[ENVIRONMENT: OS=linux, SHELL=bash, CWD=/home/user/project]

2. Multi-Agent Coordination

Coordinator Pattern (05_coordinator_system_prompt.md):

## Phased Workflow

1. **Planning Phase**: Break task into subtasks
2. **Delegation Phase**: Assign workers with specific contexts
3. **Synthesis Phase**: Merge results and resolve conflicts

## Worker Communication

- Workers receive: task description, relevant files, constraints
- Workers return: results, confidence score, blockers
- Coordinator decides: accept, retry, escalate

Implementation approach:

# Conceptual multi-agent orchestration
class AgentCoordinator:
    def execute_task(self, user_request: str):
        # Phase 1: Planning
        subtasks = self.plan(user_request)
        
        # Phase 2: Delegation
        workers = [
            self.spawn_agent("worker", task=t, context=self.get_context(t))
            for t in subtasks
        ]
        results = [w.execute() for w in workers]
        
        # Phase 3: Synthesis
        return self.merge_results(results)
    
    def spawn_agent(self, agent_type: str, task: str, context: dict):
        # Load base prompt + agent-specific addendum
        base_prompt = self.load_prompt("03_default_agent_prompt.md")
        agent_prompt = self.load_prompt(f"{agent_type}_prompt.md")
        
        return Agent(
            system_prompt=f"{base_prompt}\n\n{agent_prompt}",
            task=task,
            context=context
        )

3. Security Classification

Multi-stage auto-approval (12_yolo_auto_mode_classifier.md):

class SecurityClassifier:
    def classify_tool_call(self, tool: str, args: dict) -> str:
        """Returns: 'safe', 'unsafe', or 'uncertain'"""
        
        # Stage 1: Fast predefined rules
        if tool == "bash" and "rm -rf" in args.get("command", ""):
            return "unsafe"
        if tool == "read_file" and not self.accesses_sensitive_path(args["path"]):
            return "safe"
        
        # Stage 2: User-defined overrides
        for rule in self.user_classifier_rules:
            result = rule.evaluate(tool, args)
            if result != "uncertain":
                return result
        
        # Stage 3: Extended reasoning (slower)
        return self.llm_classify_with_reasoning(tool, args)
    
    def accesses_sensitive_path(self, path: str) -> bool:
        sensitive = ["/etc/passwd", "~/.ssh", ".env"]
        return any(s  path  s  sensitive)

User-configurable rules (.claude/auto_mode_rules.md):

rules:
  - pattern: "read_file:docs/**"
    verdict: safe
    reason: "Documentation is always safe to read"
  
  - pattern: "bash:git push *"
    verdict: unsafe
    reason: "Always confirm before pushing code"
  
  - pattern: "edit_file:**/test_*.py"
    verdict: safe
    reason: "Test file edits are low-risk"

4. Memory Hierarchy

Loading order (24_memory_instruction.md):

class MemoryLoader:
    def load_context(self, project_path: str) -> str:
        """Load memory files in priority order (earliest = lowest priority)"""
        
        layers = [
            # 1. Enterprise/managed configuration
            self.load_if_exists("/etc/claude/enterprise_policy.md"),
            
            # 2. User global preferences
            self.load_if_exists("~/.claude/global_preferences.md"),
            
            # 3. Project-level shared instructions
            self.load_if_exists(f"{project_path}/.claude/project_rules.md"),
            
            # 4. Project rules directory (supports includes)
            *self.load_directory(f"{project_path}/.claude/rules/"),
            
            # 5. Local overrides (private, gitignored)
            self.load_if_exists(f"{project_path}/.claude/local_overrides.md"),
        ]
        
        # Later layers override earlier ones
        return self.merge_with_precedence(layers)
    
    def merge_with_precedence(self, layers: list[str]) -> str:
        """Handle conflicting instructions by priority"""
        merged = {}
        for layer in layers:
            directives = self.parse_directives(layer)
            merged.update(directives)  
         .serialize(merged)

Transitive includes:

<!-- project_rules.md -->
# Project Rules

@include ./rules/code_style.md
@include ./rules/testing_requirements.md

<!-- Conditional inclusion -->
@include ./rules/python_specific.md if file_extension == ".py"

5. Context Window Management

Compaction strategy (21_compact_service.md):

class ContextCompactor:
    def compact_conversation(self, messages: list[dict]) -> list[dict]:
        """Summarize old messages to fit within context window"""
        
        # Keep recent messages verbatim
        recent_cutoff = len(messages) - 10
        recent = messages[recent_cutoff:]
        old = messages[:recent_cutoff]
        
        # Identify which old messages to keep fully
        important = self.filter_important(old)  # Tool uses, errors, decisions
        
        # Summarize the rest
        summaries = self.batch_summarize(
            [m for m in old if m not in important],
            max_tokens_per_summary=150
        )
        
        return summaries + important + recent
    
    def filter_important(self, messages: list[dict]) -> list[dict]:
        """Keep tool uses, errors, and key decisions"""
        important = []
        for msg in messages:
            if msg.get("tool_use"):
                important.append(msg)
            elif "error" in msg.get("content", "").lower():
                important.append(msg)
            elif msg.get():
                important.append(msg)
         important

6. Specialized Agent Patterns

Verification Agent (07_verification_agent.md):

## Your Role

You are an adversarial testing agent. After another agent implements a feature,
your job is to break it.

## Testing Strategy

1. **Read the implementation** - Understand what was built
2. **Generate test cases** - Focus on edge cases and error conditions
3. **Execute tests** - Run them and document failures
4. **Report findings** - Clear reproduction steps

## Test Categories

- Boundary conditions (empty input, max values)
- Error handling (invalid input, network failures)
- Race conditions (concurrent access)
- Security (injection, unauthorized access)

## Constraints

- Read-only access to implementation
- Create test files in `tests/` directory
- Use project's testing framework
- No modifications to implementation code

Explore Agent (08_explore_agent.md):

## Your Role

You explore codebases to answer questions. You have read-only access.

## Available Tools

- `read_file`: Read any file
- `list_directory`: Browse directory structure
- `search_code`: Semantic code search
- `grep`: Pattern matching across files

## Constraints

- NEVER use edit_file or write_file
- NEVER use bash to modify files
- Focus on understanding, not changing

## Exploration Strategy

1. Start broad (directory structure, README)
2. Identify entry points (main files, key modules)
3. Follow dependencies
4. Document findings concisely

7. Skill Patterns

Simplify Skill (19_simplify_skill.md) - Multi-agent parallel review:

class SimplifySkill:
    """Spawn multiple agents to review code in parallel"""
    
    def execute(self, target_files: list[str]):
        # Spawn review agents in parallel
        agents = [
            self.spawn_agent("reviewer", {
                "file": f,
                "focus": "complexity",
                "constraints": "suggest simplifications, not rewrites"
            })
            for f in target_files
        ]
        
        # Collect suggestions
        suggestions = [a.execute() for a in agents]
        
        # Coordinator merges and deduplicates
        return self.merge_suggestions(suggestions)

Skillify Skill (25_skillify.md) - Interview-based skill creation:

## Process

1. **Interview user** about the skill they want to create
   - What problem does it solve?
   - What tools/agents are needed?
   - What are success criteria?

2. **Generate skill specification**
   ```yaml
   name: custom-skill-name
   description: One-line description
   triggers: [list of natural language triggers]
   agents: [required agent types]
   tools: [required tool access]
   workflow: [step-by-step process]

3. Write skill implementation as markdown file

4. Test skill with sample scenarios

5. Save to .claude/skills/custom-skill-name.md

## Usage Examples

### Building a Custom Agent System

```python
# Using patterns from this research to build your own agent

import anthropic

class CustomAgentSystem:
    def __init__(self, api_key: str):
        self.client = anthropic.Anthropic(api_key=api_key)
        self.prompts = self.load_prompt_library()
    
    def load_prompt_library(self) -> dict:
        """Load reconstructed prompts from this repository"""
        return {
            "coordinator": open("prompts/05_coordinator_system_prompt.md").read(),
            "default_agent": open("prompts/03_default_agent_prompt.md").read(),
            "security": open("prompts/04_cyber_risk_instruction.md").read(),
        }
    
    def create_coordinator(self, task: str) -> str:
        """Create a coordinator agent for a complex task"""
        system_prompt = f"""
{self.prompts['default_agent']}

{self.prompts['coordinator']}

{self.prompts['security']}

Available sub-agents: explore, verification, implementation
Current task: {task}
"""
        
        response = self.client.messages.create(
            model="claude-3-5-sonnet-20241022",
            max_tokens=4000,
            system=system_prompt,
            messages=[{"role": "user", "content": task}]
        )
        
        return response.content[0].text

Implementing Auto-Approval Logic

import re

class ToolApprovalSystem:
    def __init__(self):
        # Based on 12_yolo_auto_mode_classifier.md
        self.safe_patterns = [
            (r"read_file", lambda args: not self._is_sensitive(args["path"])),
            (r"list_directory", lambda args: True),
            (r"search_code", lambda args: True),
        ]
        
        self.unsafe_patterns = [
            (r"bash:rm -rf", lambda args: True),
            (r"bash:sudo", lambda args: True),
            (r"edit_file:.env", lambda args: True),
            (r"bash:git push", lambda args: True),
        ]
    
    def classify(self, tool: str, args: dict) -> str:
        """Returns: 'approve', 'reject', or 'ask_user'"""
        
        tool_str = f"{tool}:{args.get('command', args.get('path', ''))}"
        
        # Check unsafe patterns first
        for pattern, condition in .unsafe_patterns:
             re.search(pattern, tool_str)  condition(args):
                 
        
        
         pattern, condition  .safe_patterns:
             re.search(pattern, tool_str)  condition(args):
                 
        
        
         
    
     () -> :
        sensitive = [, , , , ]
         (s  path.lower()  s  sensitive)

Memory System Implementation

import os
from pathlib import Path

class MemorySystem:
    def __init__(self, project_root: str):
        self.project_root = Path(project_root)
        self.memory_dir = self.project_root / ".claude"
    
    def load_all_context(self) -> str:
        """Load memory files in precedence order"""
        
        memory_files = [
            Path.home() / ".claude" / "global_preferences.md",
            self.memory_dir / "project_rules.md",
            *self.memory_dir.glob("rules/*.md"),
            self.memory_dir / "local_overrides.md",
        ]
        
        context_parts = []
        for file_path in memory_files:
            if file_path.exists():
                content = file_path.read_text()
                # Process includes
                content = self._process_includes(content, file_path.parent)
                context_parts.append(f"## From {file_path.name}\n\n{content}")
        
        return "\n\n".join(context_parts)
    
    def _process_includes(self, content: str, base_dir: Path) -> str:
        """Handle @include directives"""
         re
        
         ():
            include_path = .group()
            full_path = base_dir / include_path
             full_path.exists():
                 full_path.read_text()
             
        
         re.sub(, replace_include, content)
    
     ():
        
        .memory_dir.mkdir(exist_ok=)
        (.memory_dir / ).write_text(content)

Common Patterns for AI Agent Builders

1. Modular Prompt Assembly

Don't hardcode monolithic prompts. Use composition:

def build_agent_prompt(role: str, context: dict) -> str:
    return "\n\n".join([
        load_prompt("base_identity"),
        load_prompt(f"role_{role}"),
        load_prompt("security_boundaries"),
        format_dynamic_context(context),
    ])

2. Tool Call Batching

Reduce round-trips by batching related operations:

# Instead of: read file1, read file2, read file3
# Prefer: read multiple files in one call
{
    "tool": "multi_file_read",
    "files": ["file1.py", "file2.py", "file3.py"]
}

3. Progressive Disclosure

Start simple, add complexity as needed:

if context_window_usage < 0.5:
    # Full verbose mode
    system_prompt = build_full_prompt()
else:
    # Compact mode with summarized history
    system_prompt = build_simple_prompt()

4. Adversarial Validation

Always use a separate agent to verify work:

def implement_and_verify(task: str):
    # Agent 1: Implementation
    implementation = implementation_agent.execute(task)
    
    # Agent 2: Verification (adversarial)
    verification = verification_agent.test(implementation)
    
    if verification.passed:
        return implementation
    else:
        return implementation_agent.fix(verification.issues)

Configuration Patterns

Project-Level Configuration

<!-- .claude/project_rules.md -->

# Code Style

- Use TypeScript strict mode
- Prefer functional components
- Maximum line length: 100 characters

# Testing Requirements

- All public functions must have unit tests
- Minimum coverage: 80%
- Use Jest for testing

# Auto-Approval Rules

@include ./rules/auto_approve.yaml

# Memory Organization

@include ./rules/memory_structure.md

User-Level Preferences

<!-- ~/.claude/global_preferences.md -->

# Output Style

- Be concise
- Use emojis for status indicators
- Prefer markdown tables for structured data

# Tool Preferences

- Use multi_file_edit over single edit_file
- Prefer ripgrep over grep when available
- Always confirm before git push

Troubleshooting

Issue: Prompt Assembly Not Working

Symptom: Dynamic context not appearing in agent responses

Solution: Check cache boundaries and invalidation:

# Ensure dynamic content comes AFTER cache boundary
prompt = f"""
{CACHEABLE_PREFIX}

--- CACHE BOUNDARY ---

{dynamic_context}  # This must change per session
"""

Issue: Security Classifier Too Restrictive

Symptom: Safe operations being blocked

Solution: Add project-specific overrides:

# .claude/auto_mode_rules.yaml
rules:
  - pattern: "bash:npm install"
    verdict: safe
    reason: "Package installation is safe in this project"

Issue: Context Window Overflow

Symptom: Errors about exceeding token limits

Solution: Implement compaction earlier:

if total_tokens > MAX_TOKENS * 0.7:
    messages = compact_old_messages(messages)

Issue: Agent Coordination Failures

Symptom: Sub-agents producing conflicting results

Solution: Use explicit coordination protocol:

## Coordinator Instructions

When spawning sub-agents:
1. Assign non-overlapping file scopes
2. Provide explicit merge strategy
3. Define conflict resolution rules

Resources

• Full pattern documentation: Browse prompts/ directory
• Research discussions: Check project issues and PRs
• Related projects:
  • MCP (Model Context Protocol) for tool integration
  • LangChain for agent frameworks
  • Autogen for multi-agent systems

Best Practices

1. Start with simple mode - Use minimal prompts for straightforward tasks
2. Layer complexity gradually - Add specialized agents only when needed
3. Test security boundaries - Always validate auto-approval rules
4. Monitor context usage - Implement compaction before hitting limits
5. Version your prompts - Track changes to system prompts over time
6. Validate with adversarial testing - Use verification agents liberally
7. Document agent behaviors - Keep notes on what works and what doesn't
