VIPER phase 1 — Vision. Spawn 4-8 ideator subagents in parallel exploring distinct angles, converge with the user via AskUserQuestion, then write vision.md.
VIPER phase 2 — Investigate. Aggressive truth-finding against vision.md or the user's prompt when Vision was skipped. Spawn investigator subagents for independent sub-questions, build a shared vocabulary, eliminate assumptions, then write investigation.md.
VIPER phase 3 — Plan. Read vision + investigation, optionally hand off to OpenSpec/SpecKit/GSD if present, otherwise produce a Feature→Story→Task tree with parallel-execution metadata.
VIPER phase 4 — Execute. Spawn one viper-executor subagent per agent slot from plan.md, coordinate parallel work, merge JSONL events into execution.md. You orchestrate; you do not write code.
VIPER phase 5 — Review. Read all four prior docs + the git diff, then walk the user through a numbered, paused demo of what shipped. Like a pair-debrief after focused work.
VIPER — phased development workflow. Discovery entry point listing the five phase skills.
