compare

compare is a skill for Claude Code, Codex from anylegal-ai/anylegal-oss. It costs 32 tokens per session (562 once invoked), scanned A, original, MIT.

A document-comparison skill for examining two versions of a document. It can explain what changed and produce a Word file showing tracked additions and deletions, called a redline.

In plain words
What is it for?
Use it to compare an original with a revised document, summarise substantive edits, assess their implications, or create a redline.
Why use it?
It makes differences easier to find and assess than reading both versions manually, especially when changes may affect meaning or risk.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

compare scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Document Comparison

When to Use

Use this skill when:

  • The user uploads two versions of the same document
  • The user says /compare
  • The user asks "what changed", "what's different", or "show me the differences"
  • The user asks for a redline or tracked-changes document
  • The user received a counterparty markup and wants to understand the changes

Process

  1. Identify the two documents — ask the user which is the original and which is the revised version if not clear
  2. Read both documents via read_document
  3. Run compare with both document paths or texts — this returns a structured diff, similarity percentage, and visual output
  4. Analyze the differences:
    • What was added, removed, or modified?
    • Which changes are substantive vs. editorial?
    • Are any changes risky or favorable?
    • Do changes align with playbook positions (if available in context)?
  5. Present findings with a summary of key changes
  6. If user wants a Word redline — call run_code (default Python) to generate a DOCX with tracked changes. Open the original with python-docx, compute a diff against the revised text, and insert w:ins/w:del tracked-change markup via lxml. See /docx-editing skill for OOXML tracked change patterns. Verify the output with structural checks.

Output Format

  • Summary: Overall similarity %, number of changes, nature of changes (substantive vs. editorial)
  • Key Changes: List of the most significant changes with assessment:
    • What changed
    • Why it matters (risk/benefit)
    • Recommendation (accept / reject / negotiate)
  • Full Change List: All detected changes in order
  • Action Items: What to do next (accept, push back, request clarification)

Guidelines

  • Always present the original vs. revised framing clearly
  • Distinguish substantive changes (liability caps, notice periods, governing law) from editorial changes (formatting, numbering, defined terms)
  • Prioritize substantive changes in the summary
  • If playbook is available, flag changes that deviate from firm positions
  • When producing a DOCX redline, confirm which direction the user wants (their changes tracked, or counterparty changes tracked)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
