What problem does it solve? Writing the case analysis chapter of a Chinese accounting case-study thesis requires enforcing dozens of hidden writing conventions—paragraph opening patterns, evidence density, causal depth, theory stealth usage—that students typically learn only through trial and rejection. This Skill executes Chapter 4 writing under a strict rule engine so the draft passes mechanical and expert review on the first pass. ## Core Features & Use Cases - Matrix-Driven Paragraph Execution: Each paragraph is written row-by-row from a writing rationale matrix with 12 constraint columns, including first-sentence mode, evidence IDs, word count targets, and completion checks. - 22 Case-Type Structures: Adapts chapter organization to the diagnosed case type (audit failure, financial fraud, internal control, M&A, ESG, etc.), with distinct frameworks for ex-ante versus ex-post directions. - Subagent Delegation Mode: Detects context load and can delegate the 18,500-20,000 character chapter to a clean-context subagent with a packaged input bundle, then audits the returned draft. - Use Case: A graduate student writing an audit-failure thesis on the GaoHong case uses this Skill to produce a compliant Chapter 4 with five-step paragraphs, hidden theory usage, evidence density of at least 2 citations per 1000 characters, and a passing chapter_check.py result. ## Quick Start Ask the AI to run Phase 6 and write Chapter 4 of the thesis using the fcc-6-ch4-analysis skill after Phase 5 is completed.
