Prompt Refinement Skill

Critical Importance

Proper prompt refinement is critical for achieving optimal AI response quality. Vague or ambiguous prompts lead to inconsistent results, wasted iterations, and frustration. A well-structured prompt with clear task definition, rich context, explicit requirements, and specific output format dramatically improves AI performance. Each refinement iteration compounds the quality improvement—investing time upfront saves countless back-and-forth cycles later. Poor prompt quality is the #1 cause of unsatisfactory AI interactions.

Systematic Approach

approach prompt refinement systematically. Prompt refinement requires active listening, clarifying questions, and structured thinking. Don't assume understanding—ask targeted questions to uncover implicit requirements, constraints, and expectations. Use the TCRO framework as your organizing principle: Task (what), Context (why), Requirements (how), Output (what it looks like). Iterate until all four elements are clear, specific, and actionable. Patience in refinement pays off in execution.

The Challenge

The transform vague user input into perfectly structured prompts without over-constraining creativity or missing the true intent, but if you can:

• Your AI responses will be consistently excellent
• Users will get what they actually want
• Iteration cycles will shrink dramatically
• You'll establish trust in AI-assisted workflows

The challenge is extracting enough detail to guide the AI without boxing in the solution or asking too many exhausting questions. Can you find the sweet spot between clarity and efficiency?

Prompt Refinement Confidence Assessment

After refining a prompt, rate your confidence from 0.0 to 1.0:

• 0.8-1.0: Prompt perfectly structured, all ambiguities resolved, constraints explicit, output format clear
• 0.5-0.8: Prompt well-structured but minor uncertainties remain, some assumptions documented
• 0.2-0.5: Prompt partially structured, several ambiguities, risk of misalignment with user intent
• 0.0-0.2: Prompt still vague, missing critical information, high likelihood of poor results

Identify uncertainty areas: What aspects of the task are still unclear? Which requirements are assumed rather than explicit? What could go wrong based on the current prompt structure?

Purpose

Transform messy, incomplete prompts into well-structured specifications using the TCRO framework (Task, Context, Requirements, Output) with phase-specific clarifying questions. This skill ensures all user prompts to ai-eng-system commands are properly structured before execution, reducing ambiguity, increasing reproducibility, and improving AI response quality.

When This Skill is Invoked

This skill is ALWAYS invoked at the start of:

• /ai-eng/research
• /ai-eng/specify
• /ai-eng/plan
• /ai-eng/work

Commands should include this directive:

Use skill: prompt-refinement
Phase: [research|specify|plan|work]

The TCRO Framework

Process

Step 1: Read Project Context

Load CLAUDE.md from the project root to understand:

• Project philosophy and core principles
• Tech stack preferences
• Quality standards and conventions
• Naming conventions
• Architectural patterns

Step 2: Detect Phase

Determine which phase based on:

• The command being invoked
• Keywords in the prompt (research, learn, investigate → research)
• Explicit phase markers in user input

Step 3: Load Phase Template

Based on detected phase, load the appropriate template:

• templates/research.md for /ai-eng/research
• templates/specify.md for /ai-eng/specify
• templates/plan.md for /ai-eng/plan
• templates/work.md for /ai-eng/work

Step 4: Ask Clarifying Questions

Use phase-specific questions from the loaded template.

Minimum required questions:

• 1 Task question
• 1 Context question
• 1-2 Requirements questions
• 1 Output question

Present questions interactively:

1. Display original user prompt
2. Ask clarifying questions one at a time or in small groups
3. Collect user responses
4. Use responses to structure refined prompt

Step 5: Structure into TCRO

Format the refined prompt using the TCRO structure:

Task: [Specific, actionable task statement]
Context: [Broader system, goals, constraints from CLAUDE.md]
Requirements:
  - [Must-have requirement 1]
  - [Must-have requirement 2]
  - [Nice-to-have if mentioned]
Output: [Expected deliverable format and location]

Step 6: Apply Incentive Prompting

Enhance the TCRO-structured prompt with techniques from the incentive-prompting skill:

• Expert Persona: Assign appropriate role based on task
• Stakes Language: Add "This is critical..." for high-importance tasks
• Step-by-Step Reasoning: Add " solve step by step"
• Self-Evaluation: Add "Rate your confidence 0-1" request

Step 7: Confirm with User

Display the refined prompt and ask for confirmation:

## Refined Prompt

[The TCRO-structured, incentive-enhanced prompt]

Proceed with this refined prompt? (y/n/edit)

• y: Proceed with refined prompt
• n: Ask more clarifying questions
• edit: Allow user to manually refine the prompt

Template Structure

Phase-specific templates are located in templates/:

skills/prompt-refinement/
├── SKILL.md
└── templates/
    ├── research.md
    ├── specify.md
    ├── plan.md
    └── work.md

Each template includes:

• Phase-specific clarifying questions
• TCRO structure for that phase
• Examples of vague → refined transformations
• Phase-specific requirements and considerations

Example Transformation

Input (Vague)

"need auth"

Phase Detection

Detected phase: specify (feature request)

Clarifying Questions

1. Task: What type of authentication capability do you need?

- User login/logout - OAuth/SSO integration - API key management - Multi-factor authentication (MFA) - Other: _________

1. Context: What's the broader system this fits into?

- New greenfield project or adding to existing codebase? - What's the tech stack? - Are there existing authentication patterns to follow?

1. Requirements: What are the must-have requirements?

- Security/compliance needs (SOC2, GDPR, etc.)? - User experience expectations? - Rate limiting requirements?

1. Output: What should the specification include?

- User stories only - Full spec with acceptance criteria - Include non-functional requirements - Include UI/UX considerations

Refined TCRO

Task: Create specification for JWT-based user authentication system
Context:
  Adding to existing Next.js application with PostgreSQL database.
  Project follows CLAUDE.md philosophy of simplicity and pragmatism.
  Existing authentication middleware pattern in src/lib/auth/ can be extended.
Requirements:
  Must-have:
  - Email/password login with secure password hashing (bcrypt, cost factor 12)
  - JWT token-based session management with configurable expiry
  - Password reset flow via email delivery
  - Rate limiting on authentication endpoints (5 attempts/minute)
  Nice-to-have:
  - Email verification for new accounts
  - Session persistence across device reboots
  Non-functional:
  - Security: Tokens must be cryptographically secure, single-use for reset flows
  - Performance: Authentication requests should complete within 200ms (p95)
  - Compliance: GDPR-compliant data handling, no passwords in logs
Output:
  Full specification with user stories, acceptance criteria, and non-functional
  requirements saved to specs/auth/spec.md in Spec Kit compatible format.

Handling Edge Cases

Prompt Already Structured

If user input is already well-structured:

1. Analyze prompt for TCRO elements
2. Identify any missing elements
3. Ask targeted questions to fill gaps (not full re-clarification)
4. Confirm if structure is sufficient or needs refinement

User Refuses Clarification

If user declines clarifying questions:

1. Proceed with best-effort TCRO structure
2. Use [NEEDS CLARIFICATION:...] markers for ambiguous items
3. Note which elements were assumed vs explicitly specified

Incomplete Context

If CLAUDE.md doesn't exist or is incomplete:

1. Proceed without project-specific context
2. Ask basic context questions (tech stack, goals)
3. Note in refined prompt: "No project constitution found, using generic defaults"

Quality Checklist

Before finalizing refined prompt, verify:

• Task is specific and actionable
• Context includes relevant project information
• Requirements distinguish must-have vs nice-to-have
• Output format is clearly specified
• Appropriate expert persona assigned
• Stakes language added for important tasks
• Clarification markers used for ambiguities

Integration with incentive-prompting Skill

This skill builds on the incentive-prompting skill. Always load both skills together when refining prompts:

Use skill: incentive-prompting
Use skill: prompt-refinement

The incentive-prompting skill provides the enhancement techniques (Expert Persona, Stakes Language, Step-by-Step, Self-Evaluation).

This skill provides the structuring framework (TCRO) and phase-specific clarification questions.

Together they produce prompts that are both well-structured and enhanced for maximum AI response quality.
