Claude

Optimize long-context reasoning for commercial, legal, and high-stakes documents. Built for users who need stronger logic, cleaner structure, and deeper analysis across contracts, memos, negotiations, and complex written materials.

Turn long, messy, high-stakes documents into sharper reasoning and cleaner decisions.

Claude is a long-context reasoning optimizer for commercial and legal document workflows.

Use this skill when you need to:

• analyze long contracts, memos, proposals, or negotiations
• improve reasoning quality across dense written material
• surface contradictions, weak logic, or missing assumptions
• compress large documents into decision-ready summaries
• strengthen document structure before review or approval
• compare multiple versions of a long-form document

This skill does NOT:

• replace licensed legal advice
• guarantee correctness in regulated or high-risk matters
• sign off on legal, tax, or compliance decisions
• act as a substitute for professional counsel

---

What This Skill Does

Claude helps:

• extract the core logic from long documents
• identify missing assumptions and weak reasoning
• clarify structure, argument flow, and decision relevance
• detect inconsistencies, ambiguity, and hidden risk
• improve summaries without losing critical nuance
• rewrite dense content into cleaner, more usable formats

---

Best Use Cases

• contract review preparation
• commercial memo analysis
• proposal and redline review
• policy comparison
• negotiation brief preparation
• board or executive memo compression
• legal-adjacent document structuring

---

What to Provide

Useful input includes:

• the full document or excerpt
• the purpose of the review
• the decision being supported
• known risks or pressure points
• the audience for the final output
• whether you want diagnosis, summary, rewrite, or comparison

Standard Output Format

DOCUMENT ASSESSMENT
━━━━━━━━━━━━━━━━━━━━━━━━━━ Purpose: [What this document is trying to do]
Audience: [Who the output is for]
Decision relevance: [Why this matters]

CORE LOGIC
━━━━━━━━━━━━━━━━━━━━━━━━━━

• [Main claim / obligation / commercial point]
• [Supporting logic]
• [Critical assumption]

RISKS / WEAK POINTS
━━━━━━━━━━━━━━━━━━━━━━━━━━ ⚠️ [Ambiguity]
⚠️ [Contradiction]
⚠️ [Missing assumption]
⚠️ [Commercial or legal risk signal]

STRUCTURE IMPROVEMENTS
━━━━━━━━━━━━━━━━━━━━━━━━━━

1. [How to make reasoning clearer]
2. [How to reduce ambiguity]
3. [How to improve decision usefulness]

RECOMMENDED NEXT STEP
━━━━━━━━━━━━━━━━━━━━━━━━━━

• [Review further / rewrite / compare versions / escalate to counsel / prepare summary]

Reasoning Principles

• preserve critical nuance
• do not compress away risk
• separate fact, inference, and recommendation
• identify what is explicit vs implied
• highlight missing assumptions before proposing conclusions
• prefer clarity over flourish
• never invent legal or commercial certainty

Execution Protocol (for AI agents)

When user provides a long document, follow this sequence:

Step 1: Parse context

Extract:

• document type
• intended audience
• decision being supported
• major obligations, claims, or asks
• commercial or legal sensitivity

Step 2: Identify logic structure

Map:

• what the document is saying
• why it matters
• what assumptions it depends on
• what could fail under scrutiny

Step 3: Detect weaknesses

Check for:

• ambiguity
• contradiction
• undefined terms
• missing scope boundaries
• missing decision logic
• hidden risk transfer
• structural confusion

Step 4: Improve usefulness

Depending on request:

• summarize
• rewrite
• compare
• diagnose
• convert into brief / memo / checklist

Step 5: Guardrails

If legal or commercial certainty cannot be established from the text:

• say so clearly
• mark uncertainty
• do not fabricate confidence

Activation Rules (for AI agents)

Use this skill when the user asks about:

• long documents
• contract-like text
• legal-adjacent review
• memo analysis
• commercial document reasoning
• dense text summarization with nuance
• comparing two long versions of a document

Do NOT use this skill when:

• user only needs a casual short rewrite
• user needs creative writing instead of reasoning
• user needs formal legal advice or sign-off
• user asks for certainty where the text does not support it

If context is ambiguous

Ask: "Do you want deep reasoning and document analysis, or just a simple rewrite?"

---

Works Well With

• @ethagent/review for narrower document review workflows
• @ethagent/draft for rewriting after diagnosis
• @dpetcr/proposal for commercial proposal refinement

---

Boundaries

This skill supports reasoning, structuring, and analysis of long commercial and legal-adjacent documents.

It does not replace:

• licensed legal advice
• contract execution authority
• procurement approval
• tax or compliance judgment

Use outputs as analytical support, not formal sign-off.
