## What it does

The skill has two modes. With `--send`, it gathers the right, conduct, relationship and demand, then drafts a letter based on the enforcement posture. A pre-delivery gate runs before the final draft is written, with the approval matrix brought into that review.

With `--receive`, it accepts a path to an incoming letter or pasted text, assesses exposure, and writes an options memo with a recommendation. A firm-response recommendation can lead into send mode. Recommendations involving a declaratory judgment action or TTAB cancellation go to outside counsel under the practice profile.

It reads the practice profile at `~/.claude/plugins/config/claude-for-legal/ip-legal/CLAUDE.md` and may load matter context. Trademark rights are checked against the declared jurisdictions. Set up that profile first: placeholder markers stop the skill and direct you to `/ip-legal:cold-start-interview`.

  Draft a cease-and-desist letter (send mode) or triage one you received
  (receive mode). Use when asserting your rights against an infringer with a
  demand letter calibrated to your enforcement posture, or when an incoming
  C&D needs triage into a structured options memo with a recommendation.

# /cease-desist

Two modes. Pick one:

- `/ip-legal:cease-desist --send` — draft a cease-and-desist letter calibrated to your enforcement posture. Loud gate runs before delivery.
- `/ip-legal:cease-desist --receive` — triage a C&D someone sent you. Produces an options memo with a recommendation.

## Instructions

1. **Read the practice profile.** Load `~/.claude/plugins/config/claude-for-legal/ip-legal/CLAUDE.md`. If it contains `[PLACEHOLDER]` markers or does not exist, stop and say: "This plugin needs setup before it can give you useful output. Run `/ip-legal:cold-start-interview` — the C&D skill depends on your enforcement posture, approval matrix, and practice-area mix, none of which are configured yet."

2. **Check matter workspaces.** Per `## Matter workspaces`: if `Enabled` is `✗`, skip — skills use practice-level context. 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`."

3. **Dispatch on `$ARGUMENTS`:**
   - If `--send` is present: run send mode (below). Walk through identify-the-right, identify-the-conduct, identify-the-relationship, identify-the-demand, calibrate-to-posture, draft, and the pre-delivery gate.
   - If `--receive` is present: run receive mode (below). Ask for the incoming letter (path or pasted text), then assess, identify exposure, present options, and write the triage memo.
   - If neither flag is present: ask once — "Are we sending a cease-and-desist (you're asserting) or triaging one we received (you're defending)?" — and then dispatch.

4. **Respect the gate.** In send mode, the loud gate runs before any final draft is written to disk. Do not skip it.

5. **Respect the approval matrix.** Pull the approver for the C&D row from `## Enforcement posture → Approval matrix`. Pull automatic escalations. Surface both in the gate; do not smother them.

6. **Hand off where appropriate.** In receive mode, if the recommendation is to respond firmly, offer to chain into `/ip-legal:cease-desist --send` pre-populated with the response context. If the recommendation is to pre-empt with a DJ action or TTAB cancellation, escalate to outside counsel per the practice profile's IP litigation row — do not draft.

## Examples

```
/ip-legal:cease-desist --send
/ip-legal:cease-desist --receive ~/Downloads/incoming-cd-acme.pdf
/ip-legal:cease-desist
```
