Optimize long-context reasoning for commercial, legal, and high-stakes documents. Built for users who need stronger logic, cleaner structure, and deeper anal...

Security Scan

The skill is an instruction-only document-reasoning helper whose requested resources and runtime instructions match its stated purpose and contain no surprising requirements.

Purpose & Capability

The name, description, and declared capabilities all describe long-form document analysis (contracts, memos, comparisons). There are no unrelated environment variables, binaries, or config paths requested that would be inconsistent with this purpose.

Instruction Scope

SKILL.md instructs the agent to parse and analyze user-provided documents and to follow clear guardrails (do not provide legal certainty). It does not instruct reading unrelated files, accessing environment variables, or sending data to external endpoints.

Install Mechanism

This is an instruction-only skill with no install spec and no code files to write or execute. That minimizes on-disk installation risk.

Credentials

The skill declares no required environment variables, credentials, or config paths. The absence of requested secrets is proportionate to a document-analysis helper.

Persistence & Privilege

The skill does not request always:true or other elevated persistence. It is user-invocable and can be used by the agent per normal policy, which is expected for skills of this type.

Assessment

This skill appears internally consistent and low-risk, but you should still: 1) confirm the skill's provenance (source/homepage in skill.json differs from the top-level metadata and the source is 'unknown'); 2) avoid uploading highly sensitive or regulated documents until you verify how the platform handles data (logging, third-party calls, retention); 3) test with non-sensitive samples to confirm outputs and behavior; and 4) if you need formal legal advice, escalate to licensed counsel—the skill explicitly disclaims that role.

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.
