## What it does

This skill standardizes internal workplace investigations. It initializes matter logs in `log.yaml`, builds checklists via `sources-checklist.yaml`, and prepares structured summaries. During intake, it flags Weingarten rights and public-sector Garrity rules before witness interviews start.

You cannot invoke this skill directly. The configuration sets `user-invocable: false`. It loads behind slash commands such as `/employment-legal:investigation-open`, `/investigation-add`, `/investigation-query`, `/investigation-memo`, and `/investigation-summary`. Outputs reside in matter folders under `~/.claude/plugins/config/claude-for-legal/employment-legal/`.

Marking files does not create privilege. If counsel did not direct the investigation to provide legal advice, standard headers might mislead and fail in discovery. Counsel must confirm privilege status before generating logs.

## Install

### Claude Code (native platform)

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

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add anthropics/claude-for-legal --skill internal-investigation -a codex
```

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

### Cursor

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

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

### GitHub Copilot

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

2. **Manually: put the files in place**

```bash
npx skills add anthropics/claude-for-legal --skill internal-investigation -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/anthropics/claude-for-legal --path employment-legal/skills/internal-investigation
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add anthropics/claude-for-legal --skill internal-investigation -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/employment-legal/skills/internal-investigation/SKILL.md

## When to use it
- log investigation intake details and allegations in YAML
- identify missing documentary sources and evidence gaps
- flag Weingarten and Garrity interview constraints early
- maintain privilege headers across drafts and interview notes

## Example prompts
- /employment-legal:investigation-open
- Start an investigation into an expense fraud allegation
- Review the sources checklist for the active investigation

# Internal Investigation Skill

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

---

## Output header

Prepend the work-product header from `~/.claude/plugins/config/claude-for-legal/employment-legal/CLAUDE.md` → `## Outputs` (it differs by user role — see `## Who's using this`). Every file, log, memo, and summary produced by this skill opens with that header.

> **Distribution discipline.** Every file this skill creates — log entries, memo drafts, audience summaries, document notes — inherits the privilege and confidentiality status of the underlying investigation. Distribution beyond the privilege circle (forwarding to non-attorneys outside the investigation team, cc'ing HR without scoping, handing to the business side) can waive privilege over the entire investigation. Store these files where privileged materials live, label per the work-product header, and make every distribution decision deliberately.

## ⚠️ Privilege notice — read before proceeding

**Marking does not create privilege.** The header above reflects the intended
protection and is important to include — but it does not itself establish
privilege. Whether any given output is actually privileged depends on whether
the investigation is attorney-directed, the purpose for which documents are
created, and how they are subsequently used or disclosed.

**Before opening a matter, confirm:** Is this investigation attorney-directed?
If it is not — if HR is running it with legal in an advisory role, or if it was
```
