/radioactive

The 11-phase backbone of autonomous development.

Complete development lifecycle workflow. Chains request classification, discovery, UX design, planning, blueprint creation, execution, testing, quality review, iterative fix loop, blueprint updates, and changelog generation. Every phase has a gate — nothing proceeds without evidence.

Category

Full-Lifecycle

Execution

11 phases, sequential + gated

Goal

Provide a portable, end-to-end 11-phase development lifecycle that enforces strict quality gates from problem discovery to final review, fix iteration, institutional memory update, and changelog generation.

Scope

Applies to

  • +Non-trivial features
  • +Architectural refactors
  • +Cross-layer implementations (backend + API + frontend)

Does not cover

  • −Single-file trivial bug fixes (use thermo-fix)
  • −Pure documentation edits (use document)
  • −Isolated test additions

Triggers

"Run radioactive lifecycle""/radioactive [feature description]""Full-cycle feature development""Implement feature with end-to-end quality gate"

Inputs

  • →featureDescription: Short text (optional — triggers discovery if missing)
  • →projectSlug: Repo identifier
  • →baseBranch: Integration branch (default: main)
  • →techStack: Stack details
  • →uiInvolved: Boolean flag for frontend changes
  • →maxFixAttempts: Fix loop iterations (default: 3)

Invariants

  • 01All 11 phases must execute in exact numerical order. No skipping.
  • 02Phase 2 must wait for explicit user response before proceeding.
  • 03Phase 4 requires explicit user plan approval.
  • 04Phase 5 must scaffold a reusable workflow contract.
  • 05Phase 7 specs must pass 100%.
  • 06Phase 9 fix loop must resolve all Blockers and High findings before completion.

Procedure

  1. Phase 1CLASSIFY & INIT — Load project skill or run /workflow-blueprint init
  2. Phase 2DISCOVER — Run /brainstorming with Socratic questions. Wait for user response.
  3. Phase 3UX DESIGN — Run /ui-ux-pro-max if UI is involved (conditional)
  4. Phase 4PLAN — Run /plan-writing. Generate task.md. Gate on user approval.
  5. Phase 5BLUEPRINT — Run /workflow-blueprint. Scaffold feature contract.
  6. Phase 6EXECUTE — Implement tasks sequentially with evidence-based edits
  7. Phase 7TESTS — Run project test suite. Write tests for all changed code. 100% pass.
  8. Phase 8REVIEW — Run /thermo-nuclear-code-quality-review. Severity-ranked findings.
  9. Phase 9FIX LOOP — Run /thermo-fix × maxFixAttempts. Resolve blockers + high findings.
  10. Phase 10BLUEPRINTS — Update project skills with discovered patterns
  11. Phase 11CHANGELOG — Run /changelog-generator. Customer-facing release notes.

Outputs

  • ▸task.md: Executed task breakdown with completion status
  • ▸walkthrough.md: Decision log, UX specs, review tables, fix history
  • ▸skills/<project>/workflows/<feature>/SKILL.md: Executable contract
  • ▸Updated project skills and routing matrix
  • ▸Clean git commit on local branch
