rein: Skill for Claude Code

rein-go

Use this when the user wants one REIN-controlled flow instead of manually invoking rein-interview, rein-plan, implementation, cleanup, review, and verification as separate steps.

rein-go is the end-to-end orchestration surface for REIN.

When To Use

• The user wants one continuous REIN workflow with minimal pauses
• The task is broad enough to need clarification, planning, implementation, and post-implementation review
• A completed rein-interview bundle already exists and should feed directly into planning and implementation
• The user explicitly invokes $rein-go, /rein-go, or asks for a single flow command

When Not To Use

• The task is already a tiny single-file change
• The user explicitly wants only one stage, such as interview-only or plan-only work
• The user wants to skip clarification and planning entirely

Flow Contract

• Public entrypoint: rein go
• Wrapper triggers: $rein-go and /rein-go
• Default posture: keep going with minimal pauses once the flow starts
• Hard stop on:
  • dangerous or destructive actions that require approval
  • missing permissions or blocked tool access
  • any failed stage: plan, implementation, cleanup, review, or verify
• Preserve the current install and hook philosophy; do not turn REIN into a hook-first enforcement layer

Runtime Helper

Start the flow through the runtime:

rein go "<task>" --json

If a completed interview bundle already exists:

rein go --from-interview <slug|path> --json

Then use:

rein go status --slug <slug> --json
rein go resume --slug <slug> --json
rein go advance --slug <slug> --stage <stage> --status <completed|failed|blocked> ... --json

Treat the returned flow state as the source of truth for current stage, resume point, stop reason, and downstream stage artifacts.

Stage Order

1. Interview
   • Bare rein go "<task>" initializes the flow and starts rein-interview automatically.
   • If the flow was started with --from-interview, the interview stage is marked completed from the bundle.
   • While interview is still active, use the normal rein interview ... runtime commands and present the user-facing interview exactly like rein-interview does, including the clarity score and question frame.
   • Never answer interview rounds on the user's behalf, never auto-crystallize, and never skip directly to planning in fresh mode.
   • If rein go resume --slug <slug> --json still returns currentStage: interview and recommends rein interview crystallize ..., the interview is not done yet; crystallize first, then resume again to advance into planning.
