PreMortemX

Evidence-backed pre-mortem risk analysis for Codex, with orchestrated adjudication, governed calibration, and a Python-first cross-platform runtime.

What it is

PreMortemX brings established risk-assessment discipline into Codex:

• specialist agent-team analysis
• orchestrated adjudication
• evidence-backed Pass / Warn / Block outcomes
• governed run artifacts for review, approvals, and calibration

30-second path

1. Open the repo root in Codex.
2. Enable PreMortemX in the Plugins UI.
3. Paste this prompt:

$premortemx Validate this architecture and identify the top design risks before implementation.

1. Expect:

• a bounded artifact check instead of guessing
• an adjudicated result
• governed artifacts for deeper review

Real example surface

• Executive summary
• Start here
• Approvals
• Risk register

Visual journey surface

The current v6a journey-view artifact turns the agent-team and harness path into a visual story with failed-future framing, rubric-based classification, and richer branch comparison:

• Journey example
• Journey HTML
• Journey JSON

Validated platforms

• Windows
• Linux through the Python runtime path

macOS is reasonably expected through Python, but not yet validated end to end.
