What problem does it solve? Technical investigations often produce scattered notes where observations, opinions, and decisions blur together, forcing leaders and engineers to reconstruct the same analysis. This Skill turns repository, product, delivery, or incident evidence into one traceable decision brief readable at three depths. ## Core Features & Use Cases - Claim Ledger: Classifies every material claim as observation, interpretation, recommendation, decision, or outcome, with exact evidence locators and freshness tracking. - Three Reading Depths: Compiles an executive brief, an engineering dossier, and an evidence trail from a single claim ledger without duplicating claims. - Structured Brief Contract: Provides a typed content model (Brief, Finding, EvidenceRef) with quality gates for persistent pages, reports, or data models. - Use Case: After a CI/CD failure, use this Skill to diagnose the causal chain from symptom to system condition, compare remediation options with tradeoffs, and render a decision page where every finding links to commit-pinned source evidence. ## Quick Start Use the engineering-decision-brief skill to analyze this repository's flaky test failures and produce an executive brief, engineering dossier, and evidence trail.
