## What it does

The skill maintains `gap-tracker.yaml` and records each gap there: what the regulation requires, which policy is affected, who owns it, and when it is due. Entries arrive from policy-diff, and duplicates are dropped by matching requirement against policy. Status values are `open`, `in-progress`, `closed` and `risk-accepted`.

The gap type sets the reminder cadence. `partial`, `full` and `new-policy` items get a reminder 30 days before the due date; `comment-decision` gets 21 days, since comment-drafting windows are short. `watch` and `comment-decision` entries are not compliance gaps — they are tracking artifacts for pre-rule items, and the status report lists them in their own bucket.

Slack notifications to owners are on by default: leave `owner_slack` empty to opt someone out. Before any send the skill previews the message and the recipient list, then waits for an explicit yes — no cadence, no batch, no repeat of yesterday's send goes out without it. If the text carries citations or deadlines, it asks separately whether to add a verify-before-acting line. A gap tied to an unverified rule is never marked overdue; rule status gets checked first.

## Requirements
- Works with: Slack

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add anthropics/claude-for-legal --skill gap-surfacer -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/gap-surfacer/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/gap-surfacer/

### Codex

```bash
npx skills add anthropics/claude-for-legal --skill gap-surfacer -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/gap-surfacer/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add anthropics/claude-for-legal --skill gap-surfacer -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/gap-surfacer/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install anthropics/claude-for-legal gap-surfacer
```

2. **Manually: put the files in place**
- File: `.github/skills/gap-surfacer/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add anthropics/claude-for-legal --skill gap-surfacer -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/anthropics/claude-for-legal --path regulatory-legal/skills/gap-surfacer
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/gap-surfacer/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add anthropics/claude-for-legal --skill gap-surfacer -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/anthropics/claude-for-legal/tree/HEAD/regulatory-legal/skills/gap-surfacer/SKILL.md

## When to use it
- list open policy gaps with owners and due dates
- de-duplicate gaps coming in from policy-diff
- remind an owner before a gap deadline passes
- separate watch items from real compliance gaps
- show which items are overdue and which need a rule-status check

## Example prompts
- show the open gaps in gap-tracker.yaml with owners and due dates
- ingest the new gaps from policy-diff and check for duplicates
- draft the Slack notice for gap GAP-001 and preview it before sending

  Reference: shared gap- and comment-tracker framework backing /regulatory-legal:gaps

  and notifies gap owners via Slack with per-send confirmation. Loaded by the gaps

# Gap Surfacer

> Owner notifications: on by default. To opt an owner out, leave `owner_slack` empty.

## Per-send confirmation — no exceptions

Before sending ANY Slack message (assignment notice, overdue reminder, bulk notification, status report):

1. Show the user exactly what you're about to send and to whom: "I'm about to send this to [N] people: [preview]."
2. Wait for an explicit yes.
3. If the message contains any citations, deadlines, or compliance conclusions, add: "⚠️ The citations in this message are unverified — I'm not confirming they're current before sending. Do you want me to add a 'verify before acting' line?"
4. Never send without the confirm. Not on a cadence. Not in a batch. Not because it was sent yesterday.

Auto-send without confirmation is the most irreversible action in this plugin, sending content this plugin's own footer says may be wrong, to people who have no way to check. That combination does not get to skip review.

## 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 `/regulatory-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/regulatory-legal/matters/<matter-slug>/`. Never read another matter's files unless `Cross-matter context` is `on`.

## Purpose

Gaps get found and then forgotten. This skill tracks them until they're closed
and notifies the people responsible for closing them.

## The tracker

Lives at `~/.claude/plugins/config/claude-for-legal/regulatory-legal/gap-tracker.yaml`:
