In plain words
What is it for?
Use it to review pasted or uploaded agreements, rank clause risks, check whether clauses fit together, and suggest redraft language where appropriate.

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

ip-clause-review 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 6d 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.

How it starts

The opening of the file, as written. The whole thing — 287 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/ip-clause-review

Reviews the IP clauses in an agreement against the practice profile in ~/.claude/plugins/config/claude-for-legal/ip-legal/CLAUDE.md. Flags assignment gaps, ownership ambiguity, license-scope issues, and IP warranty/indemnity problems. Produces a memo with per-clause findings, prioritized by risk, with suggested redline language where appropriate.

Instructions

  1. Load ~/.claude/plugins/config/claude-for-legal/ip-legal/CLAUDE.md. If placeholders present, stop and prompt: "Run /ip-legal:cold-start-interview first — I need to learn your practice profile before I can review IP clauses against it."

  2. Get the agreement: From file path, Drive link, or pasted text. If none provided, ask.

  3. Follow the workflow below. In particular:

    • Establish the agreement type and which side the company is on for IP (granting / receiving / both). The side question is per-document, not a one-time setup answer.
    • Run the assignment gap check first if the agreement is an employment, consulting, SOW, or work-for-hire document.
    • Produce per-clause findings prioritized by risk.
    • Check cross-clause consistency, not just clause-by-clause.
    • Note jurisdiction implications (moral rights, work-for-hire, implied license, patent indemnity).
  4. Output the memo per the template below — work-product header first, bottom line, assignment gap check, clauses by severity, consistency flags, jurisdiction note, approval routing.

  5. Respect the decision posture. When a clause could be read to allocate IP either way, flag for attorney review and surface the factors cutting both ways. Never silently decide a subjective allocation question.

Matter context

Matter context. Check ## Matter workspaces in the practice-level CLAUDE.md. If Enabled is ✗ (the default for in-house users), skip the rest of this paragraph — skills use practice-level context and the matter machinery is invisible. If enabled and there is no active matter, ask: "Which matter is this for? Run /ip-legal:matter-workspace switch <slug> or say practice-level." Load the active matter's matter.md for matter-specific context and overrides. Write outputs to the matter folder at ~/.claude/plugins/config/claude-for-legal/ip-legal/matters/<matter-slug>/. Never read another matter's files unless Cross-matter context is on.
