## What it does

This skill teaches the coding agent how to handle mailboxes using external command-line utilities. For Google accounts, it relies on `gog`. That enables search queries with Gmail syntax, label assignments, and thread inspection via `gog mail thread`. For standard IMAP providers, it switches to `himalaya` to list folders, forward messages, and archive mail.

The skill contains no built-in client. You must have `gog` or `himalaya` installed locally, which you can verify with `which gog himalaya`. Prior authentication is mandatory: `gog` needs OAuth authorization configured via `gog auth`, while `himalaya` reads your account details from `~/.config/himalaya/config.toml`.

## Requirements
- Works with: Gmail

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add daxaur/openpaw --skill c-email -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add daxaur/openpaw --skill c-email -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add daxaur/openpaw --skill c-email -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**

```bash
npx skills add daxaur/openpaw --skill c-email -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/daxaur/openpaw --path skills/c-email
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add daxaur/openpaw --skill c-email -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/daxaur/openpaw/tree/HEAD/skills/c-email/SKILL.md

## When to use it
- search Gmail messages using filters like is:unread or has:attachment
- read full conversation threads directly inside the agent session
- send new emails and replies through gog or himalaya
- sort messages into IMAP folders or manage Gmail labels

## Example prompts
- Search Gmail for unread messages with subject report
- Read the message thread with ID 18e3a2b4 using gog
- Send a reply to message 42 via himalaya using body.txt

This skill manages email via `gog` (Gmail) or `himalaya` (IMAP). Check availability with `which gog himalaya`.

## Gmail — `gog mail` (gogcli)

```bash
gog mail list                              # List inbox messages
gog mail list --label "INBOX" --max 20
gog mail read <message-id>                 # Read a message
gog mail send --to "user@example.com" --subject "Subject" --body "Body"
gog mail reply <message-id> --body "Reply text"
gog mail search "from:alice subject:report"
gog mail search "is:unread after:2026/02/01"
gog mail label add <message-id> "Label"
gog mail label remove <message-id> "INBOX"
gog mail archive <message-id>
gog mail trash <message-id>
gog mail labels                            # List all labels
gog mail thread <thread-id>                # View full thread
```

## IMAP — `himalaya`

```bash
himalaya list                              # List inbox
himalaya list -m 50                        # List last 50 messages
himalaya read <id>                         # Read message
himalaya write                             # Compose new message (interactive)
himalaya send --to "user@example.com" --subject "Subj" < body.txt
himalaya reply <id>
himalaya forward <id>
himalaya search "subject:report"
himalaya move <id> "Archive"               # Move to folder
himalaya delete <id>
himalaya folders                           # List folders
himalaya --account work list               # Use a specific account
```

## Usage Guidelines

- Prefer `gog` for Gmail accounts; prefer `himalaya` for non-Gmail IMAP.
- Use `gog mail search` with Gmail search syntax (from:, to:, subject:, is:unread, has:attachment).
- For sending with body content, pass the body directly or pipe a file.
- Both tools require prior authentication setup.

## Notes

- `gog` requires Google OAuth configured via `gog auth`.
- `himalaya` requires IMAP credentials in `~/.config/himalaya/config.toml`.
