Don Cheli — SDD Framework

Stop guessing. Start engineering.
_{The only framework where TDD is law, not a suggestion.}

One command. Verified code.

/dc:auto "Implement JWT authentication with refresh tokens"

Don Cheli takes your idea and delivers tested, reviewed, verified code — automatically.

  ✅ /dc:specify             8 Gherkin scenarios generated
  ✅ /dc:clarify             2 ambiguities resolved
  ✅ /dc:tech-plan           Blueprint: 3-layer architecture
  ✅ /dc:breakdown           7 TDD tasks created
  ✅ /dc:implement           14 tests pass, 91% coverage
  ✅ /dc:review              7/7 review dimensions passed

  Result: ALL PASSED — Project updated with verified code

Your project is untouched until everything passes. If anything fails, nothing changes.

The Runtime — Your code never breaks

Other frameworks give you prompts and hope the AI follows them. Don Cheli has a real TypeScript orchestrator that makes it impossible to skip rules.

How it works in 4 steps:

Step 1: The runtime creates a copy of your project (git worktree). Your real project is never touched.

Step 2: It spins up a Docker container and runs each /dc:* command inside — completely isolated.

Step 3: After each phase, real quality gates verify the output:

• Does the Gherkin spec exist? Does it have P1 scenarios?
• Do tests exist? Do they pass? Are there zero // TODO stubs?
• Is coverage >= 85%?
• Do your custom rules in .dc/gates/*.yml pass?

Step 4: Only when ALL 6 phases pass ALL gates does the code merge into your project. If anything fails → your project stays exactly as it was.

3 providers: Use your Claude Code subscription (free), OpenAI Codex, or Ollama for 100% free local execution.

Each phase has a quality gate. You don't advance without passing. No shortcuts.

3 ways to use it

# Interactive — you drive each phase
/dc:start "JWT auth"

# Autonomous — runtime drives everything, Docker isolates
/dc:auto "JWT auth"

# Terminal — without AI agent open
don-cheli auto "JWT auth"

The Iron Laws

These are not suggestions. The runtime enforces them.
