Perform comprehensive appellate-specific analysis of opening briefs, response briefs, reply briefs, and petitions for review.

Perform comprehensive appellate-specific analysis of opening briefs, response briefs, reply briefs, and petitions for review. Evaluates preservation of error, standard of review alignment, harmless error vulnerability, jurisdictional sufficiency, record appendix compliance, and appellate advocacy effectiveness. Distinct from general brief analysis by focusing on appellate-specific doctrines: issue preservation, waiver analysis, plain error review availability, mootness/ripeness, harmless error burden, and reversibility assessment. Supports three modes: pre-filing readiness (strengthen your brief), opposing brief vulnerability assessment (identify exploitable weaknesses), and appellate outcome prediction (likelihood of reversal/affirmance). Produces confidence-scored findings with Glass Box audit trail, actionable recommendations, and strategic guidance for oral argument. Jurisdiction-agnostic at baseline with [JURISDICTION-SPECIFIC] markers for US federal (FRAP), England & Wales (CPR Part 52), and Australia (Federal Court Rules).

This skill performs **appellate-specific analysis** of briefs filed in intermediate appellate courts and courts of last resort. It evaluates briefs through the lens of appellate doctrine, focusing on issues that are unique to or dispositive in appellate practice. **Key distinction from legalcode-brief-analyzer**: While `legalcode-brief-analyzer` evaluates general brief quality (IRAC structure, authority quality, writing mechanics), this skill focuses on appellate-specific doctrines that determine whether an appeal will succeed or fail: - **Preservation of error** and waiver analysis - **Standard of review** selection and consistent application - **Harmless error** vulnerability and burden allocation - **Jurisdictional sufficiency** (notice of appeal, final judgment, collateral order) - **Justiciability** (mootness, ripeness, standing on appeal) - **Record appendix** compliance and completeness - **Appellate remedy** appropriateness (reversal, vacatur, remand, affirmance) The skill is designed for three primary use cases: 1. **Pre-Filing Readiness Assessment**: Evaluate your own appellate brief before filing to identify preservation gaps, standard of review errors, and harmless error vulnerabilities that could doom the appeal. 2. **Opposing Brief Vulnerability Assessment**: Analyze the opposing party's appellate brief to identify unpreserved issues, waived arguments, concessions, and weaknesses to exploit in your response. 3. **Appellate Outcome Prediction**: Assess the likelihood of reversal, affirmance, or remand based on the strength ...
