create-prompt

<objective> Create highly effective prompts using proven techniques from Anthropic and OpenAI research. This skill covers all major prompting methodologies: clarity, structure, examples, reasoning, and advanced patterns.

Every prompt created should be clear, specific, and optimized for the target model. </objective>

<quick_start> <workflow> 1. **Clarify purpose**: What should the prompt accomplish? 2. **Identify model**: Claude, GPT, or other (techniques vary slightly) 3. **Select techniques**: Choose from core techniques based on task complexity 4. **Structure content**: Use XML tags (Claude) or markdown (GPT) for organization 5. **Add examples**: Include few-shot examples for format-sensitive outputs 6. **Define success**: Add clear success criteria 7. **Test and iterate**: Refine based on outputs </workflow> <core_structure> Every effective prompt has:

<context>
Background information the model needs
</context>

<task>
Clear, specific instruction of what to do
</task>

<requirements>
- Specific constraints
- Output format
- Edge cases to handle
</requirements>

<examples>
Input/output pairs demonstrating expected behavior
</examples>

<success_criteria>
How to know the task was completed correctly
</success_criteria>

</core_structure> </quick_start> <core_techniques> <technique name="be_clear_and_direct"> **Priority**: Always apply first

• State exactly what you want
• Avoid ambiguous language ("try to", "maybe", "generally")
• Use "Always..." or "Never..." instead of "Should probably..."
• Provide specific output format requirements

See: references/clarity-principles.md </technique>

<technique name="use_xml_tags"> **When**: Claude prompts, complex structure needed

Claude was trained with XML tags. Use them for:

• Separating sections: <context>, <task>, <output>
• Wrapping data: <document>, <schema>, <example>
• Defining boundaries: Clear start/end of sections

See: references/xml-structure.md </technique>

<technique name="few_shot_examples"> **When**: Output format matters, pattern recognition easier than rules

Provide 2-4 input/output pairs:

<examples>
<example number="1">
<input>User clicked signup button</input>
<output>track('signup_initiated', { source: 'homepage' })</output>
</example>
</examples>

See: references/few-shot-patterns.md </technique>

<technique name="chain_of_thought"> **When**: Complex reasoning, math, multi-step analysis

Add explicit reasoning instructions:

• "Think step by step before answering"
• "First analyze X, then consider Y, finally conclude Z"
• Use <thinking> tags for Claude's extended thinking

See: references/reasoning-techniques.md </technique>

<technique name="system_prompts"> **When**: Setting persistent behavior, role, constraints

System prompts set the foundation:

• Define Claude's role and expertise
• Set constraints and boundaries
• Establish output format expectations

See: references/system-prompt-patterns.md </technique>

<technique name="prefilling"> **When**: Enforcing specific output format (Claude-specific)

Start Claude's response to guide format:

Assistant: {"result":

Forces JSON output without preamble. </technique>

<technique name="context_management"> **When**: Long-running tasks, multi-session work, large context usage

For Claude 4.5 with context awareness:

• Inform about automatic context compaction
• Add state tracking (JSON, progress.txt, git)
• Use test-first patterns for complex implementations
• Enable autonomous task completion across context windows

See: references/context-management.md </technique> </core_techniques>

<prompt_creation_workflow> <step_0> **Gather requirements** using AskUserQuestion:

1. What is the prompt's purpose?

   • Generate content
   • Analyze/extract information
   • Transform data
   • Make decisions
   • Other

2. What model will use this prompt?

   • Claude (use XML tags)
   • GPT (use markdown structure)
   • Other/multiple

3. What complexity level?

   • Simple (single task, clear output)
   • Medium (multiple steps, some nuance)
   • Complex (reasoning, edge cases, validation)

4. Output format requirements?

   • Free text
   • JSON/structured data
   • Code
   • Specific template</step_0>

<step_1> **Draft the prompt** using this template:

<context>
[Background the model needs to understand the task]
</context>

<objective>
[Clear statement of what to accomplish]
</objective>

<instructions>
[Step-by-step process, numbered if sequential]
</instructions>

<constraints>
[Rules, limitations, things to avoid]
</constraints>

<output_format>
[Exact structure of expected output]
</output_format>

<examples>
[2-4 input/output pairs if format matters]
</examples>

<success_criteria>
[How to verify the task was done correctly]
</success_criteria>

</step_1> <step_2> **Apply relevant techniques** based on complexity:

• Simple: Clear instructions + output format
• Medium: Add examples + constraints
• Complex: Add reasoning steps + edge cases + validation</step_2>

<step_3> **Review checklist**:

• Is the task clearly stated?
• Are ambiguous words removed?
• Is output format specified?
• Are edge cases addressed?
• Would a person with no context understand it?</step_3> </prompt_creation_workflow>
