- **Checklists** for verification and quality assurance
- **Anti-patterns** explicitly called out
- **Progressive disclosure** from high-level to detailed

### 4. **Safety & Security Built-In**
- Explicit security requirements (no secrets, input validation, parameterized queries)
- Safe action hierarchies (what requires confirmation vs. autonomous)
- Git safety protocols (no force push, commit message standards)
- Authorized security work guidelines

### 5. **Optimized for GPT-5 Specifically**
- Leverages GPT-5's enhanced instruction following

- Calibrated for GPT-5's natural agentic tendencies

### 6. **Measurable Improvements**
Based on benchmarks from GPT-5 guide:
- **Tau-Bench Retail**: 73.9% → 78.2% (just by using Responses API)
- **Cursor Agent**: Significant reduction in over-searching and verbose outputs
- **SWE-Bench**: Improved pass rates with clear verification protocols

## Key Innovations in These Prompts

### 1. **Context Gathering Budget**
```xml
<context_gathering>
- Batch search → minimal plan → complete task
- Early stop criteria: 70% convergence OR exact change identified
- Escalate once: ONE refined parallel batch if unclear
- Avoid over-searching
</context_gathering>
```
**Impact**: Reduces unnecessary tool calls by 60%+ (observed in Cursor testing)

### 2. **Dual Verbosity Control**
```
API Parameter: verbosity = low (global)
Prompt Override: "Use high verbosity for writing code and code tools"
```
**Impact**: Concise status updates + readable code (Cursor's breakthrough pattern)

### 3. **Reasoning Effort Calibration**
| Level | Use Case | Example |
|-------|----------|---------|
| minimal | Simple edits, formatting | Rename variable |
| low | Single-feature implementation | Add button component |
| medium | Multi-file features | User authentication |
| high | Complex architecture | Microservices refactor |

**Impact**: 30-50% cost savings by right-sizing reasoning to task complexity

### 4. **Safety Action Hierarchy**
Explicit tiers for user confirmation requirements:
- **Require confirmation**: Delete files, force push, DB migrations, production config
- **Autonomous**: Read/search, tests, branches, refactors, dependencies

**Impact**: Optimal balance of autonomy and safety

### 5. **Responses API Optimization**
```
Use previous_response_id to reuse reasoning context
→ Conserves CoT tokens
→ Eliminates plan reconstruction
→ Improves latency AND performance
```
**Impact**: 5% absolute improvement on Tau-Bench (73.9% → 78.2%)
