## What it does

The skill evaluates IP provisions across employment, consulting, SOW, vendor, and licensing agreements. It benchmarks contract language against your practice profile stored at `~/.claude/plugins/config/claude-for-legal/ip-legal/CLAUDE.md`. The result is a structured memo containing clause-by-clause findings, consistency checks, jurisdiction notes, and concrete redline suggestions.

Work begins by identifying agreement posture: whether the company grants rights, receives rights, or both. For consulting or work-for-hire agreements, it runs an assignment gap check first. It flags missing present-tense assignment phrasing, narrow IP definitions, lack of further assurances, and absent moral rights waivers.

This skill halts immediately if the practice profile contains unresolved placeholders. You must run `/ip-legal:cold-start-interview` beforehand to set jurisdictional rules and approval thresholds. When language permits multiple legal interpretations, it surfaces factors for counsel rather than resolving ambiguities on its own.

  Review the IP clauses in an agreement — assignment, ownership, license

# /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.
