Phase 1: Discover

Declarative phase skill. Invoked by the prd-taskmaster orchestrator when current_phase is DISCOVER. Never called directly by a user.

The one rule: invoke superpowers:brainstorming for discovery, intercept before it chains to writing-plans, we control the exit, not the brainstorm skill.

Entry gate

1. Call mcp__plugin_prd_go__check_gate(phase="DISCOVER", evidence={}) for diagnostics.

   check_gate is an EXIT gate: it verifies the evidence to advance, not to enter. On first DISCOVER entry you have no evidence yet (the User Approval / Self-Approval Gate below produces user_approved=true OR auto_classification=CLEAR with assumptions_documented), so a gate_passed: false here is EXPECTED, the state machine's legal transitions already guarantee only legal entry.

   • First entry (no evidence yet): note the result and continue with the Procedure.
   • Re-entry: if the gate reports violations, report them and stop, it protects against re-running a completed phase or skipping ahead from SETUP.

2. Detect execution context. If any of the following signals are present, switch to Autonomous Mode:

   • .claude/ralph-loop.local.md exists in the project root
   • An auto-enter / auto-approve daemon is running against this session
   • The skill was invoked with an explicit --autonomous flag
   • Parent orchestrator is a cron, /pentest-wtf, or /ralph-loop Otherwise proceed in Interactive Mode (default).

Discovery checklist

Copy into your response before running the procedure:

DISCOVERY CHECKLIST:
- [ ] Mode detected (Interactive vs Autonomous)
- [ ] Goal captured from skill args or soul purpose
- [ ] Adaptive questions completed (one at a time)
- [ ] Constraints extracted and listed
- [ ] Scale classified (Solo / Team / Enterprise)
- [ ] Discovery summary captured for GENERATE phase
- [ ] User approved (Interactive) or summary committed (Autonomous)
