## Standardized Prompt Format
Every prompt follows the same validated structure:
```markdown
# [Prompt Name]
## Metadata
- **ID**: `category-prompt-slug`
- **Version**: 1.0.0
- **Category**: Primary category
- **Tags**: searchable, keywords, here
- **Complexity**: simple | intermediate | advanced
- **Interaction**: single-shot | conversational | iterative
- **Models**: Claude 3+, GPT-4+
## Overview
2-3 sentences explaining what the prompt does and who it's for.
## When to Use
- Specific scenario 1
- Specific scenario 2
**Don't use for**: Anti-patterns where this prompt isn't appropriate

## XML Tag Structure
The prompt section uses semantic XML tags for consistent parsing:
| Tag | Purpose | Content |
| ------------------------ | ------------------- | ---------------------------------------------------- |
| `<role>` | Expert identity | Specific credentials, experience, reasoning approach |
| `<context>` | Situation framing | When used, success criteria, key assumptions |
| `<input_handling>` | Input specification | Required vs optional inputs with defaults |
| `<task>` | Process steps | 3-7 numbered action steps |
| `<output_specification>` | Deliverable format | Format, length, structure, must-include elements |
| `<quality_criteria>` | Success measures | Objective standards and anti-patterns |
| `<constraints>` | Hard boundaries | Non-negotiable limits on scope/format |
---
## Quality Gates
Every prompt passes these 11 validation checks:
| Gate | Requirement |
| --------------------- | ------------------------------------------------------------------------------------------ |
| `metadata_complete` | All required fields present (ID, Version, Category, Tags, Complexity, Interaction, Models) |
| `overview_concise` | 3 sentences or fewer, no marketing fluff |
| `role_specific` | Concrete expertise defined, not "I'll help you" |
| `inputs_categorized` | Required vs optional distinguished with defaults |
| `task_structured` | 3-7 clear numbered steps |
| `outputs_specified` | Format + length + requirements for each deliverable |
| `criteria_measurable` | Objective quality standards, not vague aspirations |
| `example_realistic` | Input shows real usage (20-200 words) |
| `example_concise` | Output demonstrates pattern (100-600 words) |
| `no_duplication` | No repeated information across sections |
| `copy_paste_ready` | Prompt section is standalone and clearly delimited |

## Quick Start
### Using Prompts
1. **Browse** the [prompts directory](https://github.com/aj-geddes/useful-ai-prompts/blob/HEAD/prompts/) or [web interface](https://aj-geddes.github.io/useful-ai-prompts/)
2. **Copy** the content within the `## Prompt` section (including XML tags)
3. **Paste** into ChatGPT, Claude, or your preferred AI assistant
4. **Provide** your specific input - the prompt handles the rest
### Example: Competitive Analysis
```text
<role>
You are a competitive intelligence strategist with 12+ years of experience
in market analysis, having led competitive strategy for both startups and
Fortune 500 companies.
</role>
<context>
Businesses need competitive intelligence to make informed strategic decisions.
Success means identifying specific opportunities that inform immediate action.
</context>
<input_handling>
Required: Industry, top competitors, current market position
Infer if not provided: Geographic scope, analysis timeline
</input_handling>
<task>
1. Map competitive landscape with positioning matrix
2. Profile key competitors (strengths, weaknesses, strategies)
3. Identify competitive gaps and white space opportunities
4. Create action recommendations with timelines
</task>
<output_specification>
- Format: Strategic analysis with visual frameworks
- Length: 500-800 words
- Must include: Positioning map, competitor profiles, action plan
</output_specification>
