| description | Creates a NEW Architectural Decision Record (ADR) documenting a specific architectural decision. Use when the user requests "Create ADR for [topic]", "Document decision about [topic]", "Write ADR for [choice]", or when documenting technology choices, patterns, or architectural approaches. Do NOT use for reviews (use architecture-review or specialist-review), checking existing ADRs (use architecture-status), or general documentation. |

Create Architectural Decision Record (ADR)
Creates structured ADRs following the framework's template.
Process
1. Gather Context
Ask if needed:
- What decision is being made?
- What problem does it solve?
- What alternatives were considered?
- What are the trade-offs?
2. Generate ADR Number
ls .architecture/decisions/adrs/ | grep -E "^ADR-[0-9]+" | sed 's/ADR-//' | sed 's/-.*//' | sort -n | tail -1
New ADR = next sequential number (e.g., if highest is 003, create 004)
3. Validate and Sanitize Input
Security: Sanitize user input to prevent path traversal and injection:
- Remove or replace:
.., /, \, null bytes, control characters
- Convert to lowercase kebab-case: spaces → hyphens, remove special chars
- Limit length: max 80 characters for filename portion
- Validate result: ensure filename contains only [a-z0-9-]
4. Create Filename
Format: ADR-XXX-kebab-case-title.md
Examples:
ADR-001-use-react-for-frontend.mdADR-002-choose-postgresql-database.md
Valid input: "Use React for Frontend" → use-react-for-frontend
Invalid blocked: "../etc/passwd" → sanitized or rejected
5. Check Configuration
- Read
.architecture/config.yml to check if pragmatic_mode is enabled
- If enabled and applies to ADR creation, include Pragmatic Enforcer analysis
6. Write ADR
Use the template from .architecture/templates/adr-template.md:
Core sections:
- Status, Context, Decision Drivers, Decision, Consequences
- Implementation, Alternatives Considered, Validation, References
If pragmatic_mode is enabled: Add Pragmatic Enforcer Analysis section:
- Necessity Assessment (0-10): Current need, future need, cost of waiting, evidence
- Complexity Assessment (0-10): Added complexity, maintenance, learning curve, dependencies
- Alternative Analysis: Review if simpler alternatives adequately considered
- Simpler Alternative Proposal: Concrete proposal for simpler approach
- Recommendation: Approve / Approve with simplifications / Defer / Recommend against
- Pragmatic Score: Necessity, Complexity, Ratio (target <1.5)
- Overall Assessment: Appropriate engineering vs over-engineering
If deferrals enabled: Track deferred decisions in .architecture/deferrals.md
7. Save ADR
Write to: .architecture/decisions/adrs/ADR-XXX-title.md
8. Report to User
Created ADR-XXX: [Title]
Location: .architecture/decisions/adrs/ADR-XXX-title.md
Status: [Status]
Key Points:
- Decision: [Summary]
- Main benefit: [Key benefit]
- Main trade-off: [Key trade-off]
Next Steps:
- [Immediate action 1]
- [Immediate action 2]
When to Create ADRs
Do create for:
- Technology choices (frameworks, databases, languages)
- Architectural patterns (microservices, event-driven, etc.)
- Infrastructure decisions (cloud provider, deployment)
- Security approaches (authentication, encryption)
Don't create for:
- Implementation details (function names, variable names)
- Temporary decisions
- Minor decisions with limited impact
Status Lifecycle
- Proposed: Documented but not approved
- Accepted: Approved and should be implemented
- Deprecated: No longer best practice
- Superseded: Replaced by newer ADR (reference it)
Related Skills
Before Creating ADR:
- "What's our architecture status?" - Check existing ADRs to avoid duplication
- "List architecture members" - See who should review the decision
After Creating ADR:
- "Ask [specialist] to review [the ADR]" - Get focused expert review
- "Start architecture review for [version]" - Include in comprehensive review
Workflow Examples:
- Create ADR → Ask Security Specialist to review → Revise ADR
- Architecture review → Create ADRs for key decisions → Status check
Notes
- Focus on "why" more than "what"
- Be honest about trade-offs
- Keep it concise but complete
- ADRs can be updated as new information emerges
