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 By the time the spec is done, it's already outdated.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.
Tech Spec Creation: Manual vs. resetDocs
| Task | Manual Process | resetDocs |
|---|---|---|
| Document architecture decisions | 2-3 hours writing and reviewing | 20 seconds - extracted from Slack thread |
| Create system diagrams | 2-3 hours in draw.io or Lucidchart | 30 seconds - auto-generated Mermaid diagrams |
| Write API specifications | 2 hours manually documenting endpoints | 15 seconds - AI-generated from context |
| Create sequence diagrams | 1-2 hours mapping flows | 20 seconds - auto-generated |
| Total time | 6-10 hours | 90 seconds |
What's Included in the Technical Spec Template
All sections auto-generated from Slack engineering discussions, with editable diagrams.
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
Pros & Cons of resetDocs Technical Spec Template
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
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.
