Contrarian Corpus
Claude Code skill

adversarial-research

A structured knowledge base for Claude Code that teaches it to build contrarian investment arguments — activist campaigns, short theses, persuasive investor memos — following the patterns validated across 670 real-world decks from the world's top contrarian funds.

What it does

The skill codifies the rhetorical and structural grammar of contrarian investor arguments: when to deploy a peer-gap chart, how to structure a sum-of-parts reveal, when to name a villain and when to stay impersonal, how to open a deck so the thesis lands in the first ten seconds, and how to close it so the reader knows exactly what to do.

Invoke it whenever you're building an investor-facing adversarial argument. Claude reads the skill's SKILL.md, loads the relevant sub-files (patterns, theses, valuation frames, slide recipes), and walks you through an 8-block drafting workflow grounded in examples from the corpus.

Once installed, the skill activates on prompts like "build an activist thesis on [target]", "structure a short report", "write a contrarian memo about [company]", or "help me design a peer-gap chart".

When to invoke

  • Building an activist campaign thesis — long with proposed changes
  • Writing a short-seller report — alleging overvaluation, fraud or broken model
  • Structuring a contrarian investment memo for internal circulation
  • Drafting a letter to a board or shareholders
  • Designing the slide architecture for any of the above
  • Critiquing a prevailing consensus with a structured counter-argument

About the corpus

The evidence base that makes the skill reliable.

The skill is not built on abstraction. Every pattern, thesis and framework is distilled from concrete documents authored between 2002 and 2026 by Pershing Square, Elliott Management, Starboard Value, Trian Partners, Greenlight Capital, Third Point, Carl Icahn, Ackman, Peltz, Einhorn, Loeb, Hohn — and short-sellers Muddy Waters, Hindenburg Research, Citron, Kerrisdale, Spruce Point and more.
