Build or review an element chart — a patent claim chart (infringement, invalidity, or review) or a civil element chart for any cause of action or defense — with every cell pin-cited and gap detection as the priority output. Use when the user asks for a claim chart, element chart, proof chart, infringement or invalidity contention, element-by-element mapping, or asks "what are we missing to prove [claim]".

~/.claude/plugins/config/claude-for-legal/litigation-legal/CLAUDE.md → role, work-product header, decision posture, document storage.matter.md (side, jurisdiction, phase, theory, pleadings).--patent → patent claim chart. Require patent number and at least one asserted claim. Sub-modes: --infringement, --invalidity, --review.--civil → civil element chart. Require the cause of action (or defense) and the side.references/element-templates.md in the skill directory for the baseline element list. Confirm the controlling pattern instruction or statute with the user before mapping.=, +, -, @, tab, or CR._sources companion), and Excel or Sheets per user preference. Work-product header on every output.claim-charts/ folder if a matter is active; otherwise the practice-level claim-charts/ folder. Append a one-line entry to history.md if a matter is active.Before working with a set of litigation documents, ask: "Were any of these documents obtained through disclosure or discovery in legal proceedings?" If yes:
Confirm: "This use is within the proceedings in which the documents were disclosed, or I have permission / consent, or the documents are now public." If not confirmed, flag it: "⚠️ Disclosed documents may have use restrictions. Confirm this use is permitted before proceeding."
Put this at the top of every output. Do not drop it. Do not soften it.
This chart is a draft for attorney analysis and verification, not a filed contention, an MSJ brief, an opening statement, or a legal opinion. Every mapping is a lead the attorney must verify against the source. The elements listed come from pattern jury instructions, the Restatement, or the claim language as parsed — the controlling authority in the user's jurisdiction (CACI / NYPJI / the circuit's pattern charge / the governing statute / a Markman order) may differ and always controls. Gap detection is a starting point for discovery or a motion; it is not a conclusion about the merits.
Under-flagging a gap is a one-way door — a complaint filed without plausibility on an element, an MSJ response served without evidence for a disputed element, or a case tried without proof of damages. Over-flagging is a two-way door — the attorney clears flags in review. The default is biased toward the two-way door.
