Technical Spec Template with Auto-Generated System Diagrams

Engineering technical specification template with AI generation. Turn technical Slack discussions into complete specs with architecture diagrams, API docs, and data models in 60 seconds.

Technical Specs Take Engineers Away from Coding

Engineering teams spend 6-10 hours per sprint writing technical specs. Creating system diagrams in draw.io or Lucidchart adds another 2-3 hours. By the time the spec is done, it's already outdated. resetDocs generates complete technical specs with architecture and sequence diagrams directly from your Slack engineering discussions.

Generate Tech Specs from Engineering Slack Threads

1. Discuss in Slack

Have your technical discussion in Slack. Share code snippets, architecture ideas, and API designs.

2. AI Generates Spec

Tag @resetDocs and our AI creates a complete technical spec with system diagrams and API docs.

3. Share & Iterate

Edit diagrams inline, add implementation details, then export to Confluence, Notion, or GitHub.

Auto-Generated Diagrams

System Architecture
Component diagrams showing services, databases, and external integrations
Sequence Diagrams
Request flows between services with authentication and error handling
ER Diagrams
Database schema with relationships, constraints, and indexes
API Flow Charts
REST/GraphQL endpoint flows with status codes and payloads

Pros & Cons of resetDocs Technical Spec Template

Pros

Saves 6-9 hours per tech spec vs manual writing

Auto-generates system, sequence, and ER diagrams

Diagrams use Mermaid (version control friendly)

Extracts API specs from code snippets in Slack

Export to Markdown, Confluence, Notion, or GitHub

Cons

Best with structured technical discussions (≥15 messages)

Complex distributed system diagrams may need manual refinement

AI may not capture all edge cases without explicit mention

Requires Slack for automatic generation (or manual file upload)

Best Practices for Engineering Tech Specs

1. Include Code Snippets in Slack

Share API endpoint examples, data model snippets, or pseudocode in your Slack thread. resetDocs will extract and format them properly in the spec.

2. Discuss Trade-offs Explicitly

Mention architectural trade-offs ("SQL vs NoSQL", "microservices vs monolith") in your discussion. The AI will capture these in the "Technical Decisions" section.

3. Attach Existing Diagrams

Upload whiteboard photos or existing architecture diagrams to Slack. resetDocs will reference them and improve generated diagrams based on visual context.

4. Specify Performance Requirements

Call out SLAs, latency targets, or throughput requirements ("<100ms p99", "1M requests/day"). These will populate the Performance section.

5. Version Control Your Specs

Export specs as Markdown with Mermaid diagrams. Commit to GitHub alongside code for proper version control and review workflows.
