oxi-cli 0.1.4-alpha

//! Super-review skill for oxi
//!
//! Performs deep, honest system analysis that goes beyond superficial
//! pass/fail checklists. The skill:
//!
//! 1. **Understands the project first** — reads manifests, docs, structure
//!    to grasp the system's purpose before judging anything
//! 2. **Evaluates each domain against the system's purpose** — architecture
//!    isn't judged in isolation; it's judged by how well it serves the system
//! 3. **Produces honest assessments with evidence** — every claim cites
//!    specific code, every severity rating matches reality
//! 4. **Finds cross-cutting patterns** — connects dots across domains to
//!    surface issues invisible to per-domain analysis
//!
//! The module provides:
//! - A [`SuperReviewSession`] that tracks the review lifecycle
//! - Domain-specific analysis types ([`DomainAssessment`], [`Evidence`], etc.)
//! - A markdown renderer that produces the structured review document
//! - Project context gathering (manifest reading, directory walking)
//! - A skill prompt generator for the LLM-driven review workflow
