| description | Phase B of the solution-design workflow: validate a proposed solution with security review, architecture critique, quality gates, first-principles audit, and optional multi-model adversarial review. |
Phase Validate
Use this skill when the user asks for /phase-validate, solution validation, architecture validation, adversarial review, or pre-implementation validation of a plan.
Purpose
Find weaknesses in a solution before implementation begins.
Workflow
- Load the latest proposal, PRD, or design artifact.
- Run a security and privacy review of the proposed design.
- Run architecture review for feasibility, scalability, maintainability, and operational risk.
- Apply first-principles audit:
- Is every requirement justified?
- What can be deleted?
- Is the simplest viable version clear?
- Are optimizations happening before simplification?
- Which constraints are assumptions?
- If external review tools are available, run an independent critique through Codex, Gemini, or another configured reviewer.
- Merge findings, revise the proposal, and revalidate up to 3 rounds.
Output
Use this shape:
VALIDATION: PASS | FAIL
Security: PASS | FAIL
Architecture: PASS | FAIL
External Review: PASS | FAIL | SKIPPED
Iterations: N/3
Key Findings:

End with PHASE_VALIDATE_PASS or PHASE_VALIDATE_FAIL.
