SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Prepares teams to stress-test Legion plans by performing structured pre-mortem analysis and assumption hunting before execution.

Core Features & Use Cases

  • Two-pass critique workflow: pre-mortem inversion to surface failure headlines and assumption hunting to challenge hidden beliefs.
  • Critique routing and mitigation: generates actionable recommendations, plan section mapping, and verdicts to guide execution.
  • Schema conformance and wave-overlap checks: validates plan metadata and detects cross-plan conflicts in the same wave.
  • Agent-driven review: recommends skeptical agents and provides routing for critique tasks.
  • Operational guardrails: ensures verification_commands exist and artifacts are tracked.

Quick Start

After generating Legion plans, run the plan-critique analysis to surface risks and assumptions before execution.

FAQPage Schema
How do I run a pre-mortem analysis on Legion plan files before execution?

Pre-mortem analysis on Legion plan files is performed through a two-pass critique workflow that surfaces failure headlines and challenges hidden assumptions. It validates schema conformance and detects cross-plan conflicts to generate actionable mitigations before deployment.

What is assumption hunting and how does it improve plan safety?

Assumption hunting is a structured critique pass that challenges hidden beliefs within Legion plans before execution. It identifies critical risks by tracking unverified verification_commands and cross-references plan sections to produce actionable routing and mitigation verdicts.

How do I detect wave overlaps and schema conformance issues in multiple plan phases?

Detecting wave overlaps and schema conformance issues requires applying structured critique checks across multiple plan phases in Legion plan files. The analysis validates plan metadata and flags cross-plan conflicts occurring within the same wave to prevent execution failures.

Can I use agent-driven routing to review and critique execution plans?

Agent-driven routing can be used to review Legion plans by recommending skeptical agents for critique tasks. The analysis provides operational guardrails that ensure verification_commands exist and artifacts are tracked before assigning execution routes.

When should I not use automated plan-critique for risk-analysis?

Automated plan-critique for risk-analysis should not be used when Legion plan files lack multiple wave plans or defined verification_commands. The critique workflow depends on structured plan metadata and cross-plan phase data to successfully detect conflicts and map mitigation verdicts.
