npx claudepluginhub juancruzrossi/neuralSpec-Driven Development framework for AI Coding Agents
A lightweight, token-efficient Spec-Driven Development framework for AI coding agents. Turns vague ideas into verified implementations through disciplined phases — no bloat, no ceremony, just structured execution that works.
interview → plan → execute → review → archive
Most AI agent failures aren't about bad code — they're about unclear requirements, fantasy plans, context rot, and "done" without evidence. Neural addresses each failure mode with a specific phase:
| Failure Mode | Neural Phase | How |
|---|---|---|
| Vague requirements | Interview | Socratic questioning with selective pressure |
| Plans based on assumptions | Plan | Mandatory codebase exploration + adversarial self-review |
| Quality degradation as context window fills | Execute | Fresh context window per subagent |
| "Done" but it's stubs | Review | 4-level goal-backward verification |

/neural:interview — Clarify before you buildSocratic interview that identifies gray areas in your requirements and resolves them one by one. Uses selective pressure — challenges assumptions only where risk is high. Locks decisions into a BRIEF.md. Detects git status and handles non-git projects gracefully.
/neural:plan — Plan with adversarial reviewGenerates an implementation plan with tasks, dependencies, and wave grouping for parallel execution. Runs a self-adversarial pass ("what can go wrong?"). Optionally sends the plan to Codex for cross-review — you decide which suggestions to apply.
/neural:execute — Parallel execution with fresh contextGroups tasks into dependency waves. Dispatches independent tasks to parallel subagents, each with a clean context window — no accumulated noise, no quality degradation. Smart model routing: routine tasks go to lightweight models, complex tasks to premium ones. Every subagent verifies its own work before committing.
/neural:review — Verify against the goal, not the task listTwo-layer verification:
/neural:address-review — Fix what review foundParses REVIEW.md, builds a fix plan from blocking issues and warnings, and executes fixes with verification. No manual triage needed.
/neural:quick — Fast-path for small tasksThree questions, inline plan, direct execution, light review. No files generated. For when the task is clear and small.
/neural:debug — Root-cause investigationFour-phase systematic debugging: investigate → analyze → hypothesize → implement. No fixes without root cause.
/neural:status — Where am I?Shows progress of all features in .neural/wip/ with next-step suggestions. Detects in-progress work on session start.
/neural:archive — Clean upMoves completed features from .neural/wip/ to .neural/archive/.
All Neural artifacts live in .neural/ at your project root:
.neural/
├── wip/
│ └── auth-system/
│ ├── BRIEF.md ← interview output
│ ├── PLAN.md ← plan output
│ └── REVIEW.md ← review output
└── archive/
└── user-onboarding/
├── BRIEF.md
├── PLAN.md
└── REVIEW.md
Add .neural/ to .gitignore or commit it — your choice. The artifacts are human-readable and useful for team context.
Clarify before you code. The interview phase forces ambiguities to the surface before planning begins. Decisions are locked, not revisited.
Fresh context per task. Each execution subagent gets a clean context window with only what it needs. No accumulated noise, no quality degradation on task 8 because of what happened on task 1.
Verify against goals, not tasks. Task completion ≠ goal achievement. A "create chat component" task can complete when the component is a placeholder. Goal-backward verification catches this.
Git-optional. Works with or without version control. If git is initialized, Neural makes atomic commits per task. If not, it works fully local without nagging.
Token-efficient. No runtime, no daemon, no build step.
Open Design — local-first design app exposed to coding agents over MCP. Install once with your agent's plugin command and projects/files/skills are reachable through stdio.
