About
simpsons-development is a Claude Code plugin marketplace entry with five Simpsons-themed self-referential development loops built on ralph-loop stop-hook architecture. Developers choose a character loop when they want structured multi-phase automation—for specs before coding, naive iteration, adversarial testing, production resilience drills, or ongoing quality governance. Install with claude plugin add https://github.com/reggiechan74/simpsons-development and run commands like /lisa-loop or /bart-loop with optional --completion-promise.
- Five loops: Lisa spec-first, Ralph iterative, Bart red-team, Homer incident, Marge governance
- Phase-aware stop hooks advance through promise-tagged methodology steps
- Extends official ralph-loop architecture with two-level completion model
- Utility commands /simpsons-status, /cancel-simpsons, and /simpsons-help
- Temporal guidance: Lisa before, Ralph during, Bart after, Homer post-deploy, Marge always

How do I run disciplined multi-phase agent loops for specs, iteration, red-teaming, incidents, and quality without manually re-prompting each stage?
Run Simpsons-themed multi-phase development loops—spec-first, iterative build, red-team, incident response, and quality governance—with stop-hook automation.
Who is it for?
Developers who want themed but structured ralph-loop extensions with explicit phase promises and stop-hook enforcement.
Skip if: Teams wanting a single generic loop or those uncomfortable with character-themed command names and protocols.
What you get
A .claude/simpsons-loop.local.md state file drives phase progression until the completion promise is met or iterations exhaust.

FAQ
Do I still need the separate ralph-loop plugin?
No. Ralph Wiggum's iterative loop is included as /ralph-loop inside Simpsons Development.
How do phases advance?
Stop hooks read .claude/simpsons-loop.local.md and advance when Claude's output contains the current phase's promise tag.
Which loop should run when?
Lisa before building, Ralph during, Bart after, Homer post-deploy, and Marge for ongoing quality governance.
