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.
