✨ The Magic of /do - Just Three Commands (one of thousands of use cases!)
# 1. Describe your feature (natural language)
/specweave:increment "Add real-time chat with typing indicators"

🤖 PM Agent asks: "Who will be chatting? Store messages? Scale?"
✅ Creates: spec.md (user stories + AC-IDs)
✅ Creates: plan.md (architecture + test strategy 88%)
✅ Creates: tasks.md (8 tasks, 45 tests embedded)
📊 Estimate: 4-6 hours deterministic work, 88% coverage. Proceed? (Y/n)

# 2. Type one command. That's it.
/specweave:do

⚙️  Working on T-001: ChatService [TDD mode]
    ✅ Tests created (5 tests)
    ✅ Implementation complete
    ✅ Coverage: 92% (target: 90%)
    ✅ Docs auto-updated (hooks)

⚙️  Working on T-002: MessageRepository...
    [continues autonomously through all 8 tasks]

# 3. Check status anytime
/specweave:progress
📊 Progress: 8/8 tasks (100%)
✅ Coverage: 90% (target: 88%)
✅ All tests passing
🎉 Ready to ship!
That's it. No back-and-forth messages. No manual test writing. No doc updates. Just working software.
This is just 1 of thousands of use cases—from microservices to ML pipelines to enterprise apps!

SpecWeave is Built With SpecWeave

This isn't just a framework we made — it's the framework we use every day. 70+ completed increments, full specs, living docs, and real DORA metrics. Every feature you see was built spec-first.

70+IncrementsLiveDORA MetricsAutoLiving Docs

Why SpecWeave?

Build production software with autonomous AI agents that just work—minimal interaction, maximum productivity.

🔌

70%+ Token Reduction

Modular plugin architecture loads only what you need. Active increment + relevant plugin + one agent = ~15K tokens (vs 200K+ monolithic). Measurable AI cost savings.

🏢

Brownfield Excellence

The hardest problem solved: import existing docs (Notion, Confluence, Wiki), create retroactive specs, generate ADRs and C4 diagrams. Perfect for legacy codebases.

📚

Living Documentation (Auto-Sync)

Specs and docs auto-update after every task via hooks. Always in sync with code—no drift, no manual updates, no surprises. Unique hook-based mechanism.

🔗

External Tool Sync (GitHub/JIRA/ADO)

Push specs to GitHub Issues, JIRA, and Azure DevOps. Read status back automatically. Keep your existing workflow—no tool lock-in.

🧪

Test Coverage Built-In

4-level testing strategy with full traceability—unit, integration, E2E, acceptance tests. Embedded in tasks.md. 85-90% coverage targets enforced.

🤖

15+ Specialized AI Agents

PM, Architect, DevOps, QA, Security, Tech Lead—work in parallel to minimize context usage. Pre-installed, auto-activating, production-ready.

📝

Specification-First (Source of Truth)

Define WHAT and WHY before HOW. Specifications are the source of truth, code follows. Complete traceability from requirements to tests.

⚡

Autonomous & Deterministic

Type one command, get production code in hours (not days). Auto-resume, auto-close. Minimal interaction, maximum velocity.

🌐

Universal Support (Any Stack, Any AI)

Works with ANY tech stack (TS, Python, Go, Rust, Java, C#) and ANY AI tool (Claude Code, Cursor, Copilot, Gemini, ChatGPT).

❌ Without SpecWeave

  • Tell AI: "Build me a feature"
  • Back-and-forth messages for every detail
  • Code generated without specs or architecture
  • Manually test, manually fix bugs
  • Docs drift or don't exist
  • Start over for next feature

Result: High cognitive load, constant context switching, no documentation = regression risk.

✅ With SpecWeave

  • Type /specweave:increment "feature"
  • Autonomous agents ask clarifying questions, create spec/plan/tasks, review with you
  • Type /specweave:do
  • Agents work in parallel, auto-resume, validate at milestones, update docs continuously
  • Type /specweave:progress anytime to see status
  • Type /specweave:increment "next" to seamlessly move forward

Result: Minimal interaction, natural flow. Production-ready software with living documentation and full traceability.
