name: adr description: Creates Architecture Decision Records (ADRs) using the AI-driven MADR template. Use this when the user wants to document architectural decisions, create ADRs, or record technical design choices.

ADR (Architecture Decision Record) Creator

This skill helps create comprehensive Architecture Decision Records using the AI-driven MADR template from o3-cloud/madr.

Instructions

When creating an ADR, follow these steps:

1. Ask for key information if not provided:

   • What architectural decision needs to be documented?
   • What problem are you trying to solve?
   • What options have you considered?
   • What decision was made (or needs to be made)?

2. Determine the ADR number:

   • Check for existing ADRs in docs/decisions/ or similar directories
   • Use the next sequential number (e.g., if last ADR is 0003, use 0004)

3. Create the ADR file with the naming pattern: XXXX-short-title.md (where XXXX is the zero-padded number)

4. Fill in all relevant sections of the template below, adapting based on the information provided

5. Ask clarifying questions for any sections that need more detail

ADR Template Structure

Use this template when creating ADRs:

# {short title of solved problem and solution}

## Context and Problem Statement

{Describe the context and problem statement, e.g., in free form using two to three sentences or in the form of an illustrative story.}

## Decision Drivers

- {decision driver 1, e.g., a force, facing concern, …}
- {decision driver 2, e.g., a force, facing concern, …}
- … <!-- numbers of drivers can vary -->

## Considered Options

- {title of option 1}
- {title of option 2}
- {title of option 3}
- … <!-- numbers of options can vary -->

## Decision Outcome

Chosen option: "{title of option 1}", because {justification. e.g., only option, which meets k.o. criterion decision driver | which resolves force {force} | … | comes out best (see below)}.

### Consequences

- Good, because {positive consequence, e.g., improvement of one or more desired qualities, …}
- Bad, because {negative consequence, e.g., compromising one or more desired qualities, …}
- … <!-- numbers of consequences can vary -->

### Confirmation

{Describe how the implementation of this ADR will be validated. This could include fitness functions, metrics to monitor, or specific design reviews.}

## Pros and Cons of the Options

### {title of option 1}

{example | description | pointer to more information | …}

- Good, because {argument a}
- Good, because {argument b}
- Neutral, because {argument c}
- Bad, because {argument d}
- … <!-- numbers of pros and cons can vary -->

### {title of option 2}

{example | description | pointer to more information | …}

- Good, because {argument a}
- Good, because {argument b}
- Neutral, because {argument c}
- Bad, because {argument d}
- … <!-- numbers of pros and cons can vary -->

### {title of option 3}

{example | description | pointer to more information | …}

- Good, because {argument a}
- Good, because {argument b}
- Neutral, because {argument c}
- Bad, because {argument d}
- … <!-- numbers of pros and cons can vary -->

## More Information

{You might want to provide additional evidence/confidence for the decision outcome here and/or document the team agreement on the decision and/or define when this decision when and how the decision should be realized and if/when it should be re-visited and/or how the decision is validated. Links to other decisions and resources might here appear as well.}

## AI-Specific Extensions

### AI Guidance Level

{Specify how much autonomy AI agents have when implementing this decision:}

- **Strict**: Follow the decision exactly as specified with minimal deviation
- **Flexible**: Adapt implementation details while maintaining core principles
- **Exploratory**: Research and propose alternative approaches if better options emerge

{Chosen level: [strict|flexible|exploratory]}

### AI Tool Preferences

{Document which AI systems should execute this decision and their configuration:}

- Preferred AI tools: {e.g., Claude Code, GitHub Copilot, etc.}
- Model parameters: {e.g., temperature, max tokens, etc.}
- Special instructions: {any specific guidance for AI tools}

### Test Expectations

{Define validation criteria that should be met (TDD-oriented):}

- {Expected test 1}
- {Expected test 2}
- {Performance criteria}
- {Quality metrics}

### Dependencies

{List related ADRs, system components, and external requirements:}

- Related ADRs: {links to other ADRs}
- System components: {affected modules, services, etc.}
- External dependencies: {libraries, services, APIs, etc.}

### Timeline

{Implementation deadlines and review dates:}

- Implementation deadline: {date}
- First review: {date}
- Revision triggers: {conditions that would require revisiting this decision}

### Risk Assessment

{Identify and assess risks:}

#### Technical Risks

- {Risk 1}: {description and mitigation strategy}
- {Risk 2}: {description and mitigation strategy}

#### Business Risks

- {Risk 1}: {description and mitigation strategy}
- {Risk 2}: {description and mitigation strategy}

### Human Review

{Specify approval requirements:}

- Review required: {before implementation | after implementation | both}
- Reviewers: {list of required approvers}
- Approval criteria: {what needs to be verified}

### Feedback Log

{Post-implementation notes - fill this out after implementation:}

- Implementation date: {date}
- Actual outcomes: {what actually happened}
- Challenges encountered: {issues faced}
- Lessons learned: {organizational learning}
- Suggested improvements: {for future similar decisions}

Best Practices

1. Keep it concise: ADRs should be readable in 5-10 minutes
2. Focus on "why": Explain the reasoning, not just what was decided
3. Document alternatives: Show what was considered and why it wasn't chosen
4. Update when needed: If a decision is superseded, link to the new ADR
5. Use clear language: Avoid jargon; make it accessible to future team members
6. AI sections are optional: Only fill in AI-specific sections if relevant to the decision

Example Usage

User request: "Create an ADR for choosing PostgreSQL as our database"

Your response should:

1. Find the next ADR number
2. Create a file like docs/decisions/0005-use-postgresql-for-primary-database.md
3. Fill in the template with relevant information
4. Ask for any missing details (e.g., "What other databases did you consider?", "What are the main decision drivers?")

Notes

• ADRs are typically stored in docs/decisions/ directories
• If no directory exists, ask the user where to create it
• ADRs are immutable once accepted - don't edit old ADRs, create new ones that supersede them
• The AI-specific sections are extensions to the standard MADR template for AI-assisted development
