Specification Mode transforms simple feature descriptions into working code with automatic planning and safety checks. You provide a brief description of what you want, and droid creates a detailed specification and implementation plan before making any changes.

Simple Input

Just 4-6 sentences describing what you want built

Automatic Planning

Droid creates detailed specs and implementation plans

Safe Execution

No code changes until you approve the complete plan

Enterprise Ready

Built-in security, compliance, and team standards

​
How it works

1

Describe your feature

Provide a simple description in 4-6 sentences. No need to write formal specifications.
2

Droid creates the spec

Droid analyzes your request and generates a complete specification with acceptance criteria, implementation plan, and technical details.
3

Review and approve

You review the generated specification and implementation plan. Request changes or approve as-is.
4

Implementation

Only after approval does droid begin making actual code changes, showing each modification for review.

​
Example workflow

Your input: 
Add a feature for users to export their personal data.
It should create a ZIP file with their profile, posts, and uploaded files.
Send them an email when it's ready. Make sure it follows GDPR requirements.
The export should work for accounts up to 2GB of data.
Droid generates:
  • Complete specification with detailed acceptance criteria
  • Technical implementation plan covering backend, frontend, and email
  • File-by-file breakdown of changes needed
  • Testing strategy and verification steps
  • Security and compliance considerations
You approve, then droid implements the complete solution while showing each change for review.
Specification Mode must be manually activated using Shift+Tab in the CLI. It does not automatically activate.

​
How to activate Specification Mode

To enter Specification Mode, press Shift+Tab while in the CLI. This will enable the specification planning workflow for your next request.

​
What happens during planning

Analysis phase (read-only):
  • Examines your existing codebase and patterns
  • Reviews related files and dependencies
  • Studies your AGENTS.md conventions
  • Gathers context from external sources
Planning phase:
  • Develops comprehensive implementation strategy
  • Identifies all files that need changes
  • Plans sequence of modifications
  • Considers testing and verification steps
Safety guarantees:
  • Cannot edit files during analysis
  • Cannot run commands that modify anything
  • Cannot create, delete, or move files
  • All exploration is read-only until you approve

​
Writing effective requests

Focus on outcomes: Describe what the software should accomplish, not how to build it. 
Users need to be able to reset their passwords using email verification.
The reset link should expire after 24 hours for security.
Include rate limiting to prevent abuse.
Include important constraints: 
Add user data export functionality that works for accounts up to 5GB.
Must comply with GDPR and include audit logging.
Should complete within 10 minutes and not impact application performance.
Reference existing patterns: 
Add a notification system similar to how we handle email confirmations.
Use the same background job pattern as our existing report generation.
Follow the authentication patterns we use for other sensitive operations.
Be specific about verification: Tell droid how to confirm the implementation works correctly. Consider the full user journey: Describe the complete experience, not just technical requirements. Include error scenarios: Specify how failures should be handled and communicated to users. Think about scale: Mention performance requirements and expected usage patterns.

​
Enterprise integration

Reference external requirements by pasting links: 
Implement the user management features described in this Jira ticket:
https://company.atlassian.net/browse/PROJ-123

Follow our security standards and include comprehensive error handling.
If you’ve integrated platforms through Factory’s dashboard, droid can read context from tickets, documents, and specs during analysis.

​
Benefits

Safety First

No accidental changes during exploration. See the complete plan before any modifications.

Thorough Planning

Comprehensive analysis leads to better architecture decisions and fewer surprises.

Full Control

Complete visibility into what will be done before any code changes happen.

Better Outcomes

Well-planned implementations are more likely to be correct, complete, and maintainable.

​
AGENTS.md integration

Document your project conventions to enhance Specification Mode’s planning. See AGENTS.md for more information. Specification Mode automatically incorporates these conventions, ensuring consistency with your team’s standards.

​
Breaking down large features

For complex features spanning multiple components, break them into focused phases: Phase 1: 
Implement user data export backend API and job processing.
Focus only on the server-side functionality, not the UI yet.
Phase 2: 
Add the frontend UI for data export using the API from Phase 1.
Include progress indicators and download management.
This approach allows you to validate each phase before proceeding to the next.

​
Specification approval options

After droid presents the specification, you have three options:
  1. Approve and continue - Proceed with the implementation using normal execution mode
  2. Approve and continue with auto-run enabled - Proceed with implementation and automatically enable auto-run mode for faster execution
  3. Reject, continue editing - Decline the specification and remain in Specification Mode to refine your request
The third option keeps you in Specification Mode, allowing you to iterate on your request until the specification meets your requirements.

​
What happens after approval

Once you approve a specification plan, droid systematically implements the changes while showing each modification for review. You maintain full control through the approval workflow, ensuring quality and alignment with requirements. For simpler changes that don’t need comprehensive planning, droid can proceed directly while still showing all modifications for approval. Ready to try Specification Mode? Start with a simple description of what you want to build, and let droid handle the specification and planning complexity.
