A command for managing messages in the macOS Mail app. It can list accounts and mailboxes, read and search messages, send or reply to mail, change flags, move or delete messages, and check sender authentication.

Use it to find or read messages, manage inbox organisation, send replies, update message flags, delete mail, and verify authentication details.

It brings common Mail tasks into an agent-controlled workflow instead of requiring each action through the Mail app interface.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods

npx agentmods add commands/omarshahine/apple-pim/mail

Clone the repo

git clone --depth 1 https://github.com/omarshahine/apple-pim

Or install apple-pim, the plugin that ships this one along with the rest of its 16 skills, 7 commands, 1 agent.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00027	$0.02095
Opus 5	$0.00014	$0.01047
Sonnet 5	$0.00005	$0.00419
Haiku 4.5	$0.00003	$0.00210

Security

Grade A, and why

mail scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Mail Management

Manage macOS Mail.app messages. Reads (accounts, mailboxes, messages, get, search) use a fast direct-SQLite path against Mail's local Envelope Index (milliseconds, works with Mail.app closed, needs Full Disk Access) and fall back to JXA automatically. Mutations and content search go through Mail.app via JXA/AppleScript, which requires Mail.app to be running.

Available Operations

When the user runs this command, determine which operation they need and use the mail tool with the appropriate action:

List Accounts

Use mail with action accounts to show all configured mail accounts.

List Mailboxes

Use mail with action mailboxes to list mailboxes with unread and total message counts:

Optional: account (filter by account name)

List Messages

Use mail with action messages to list messages in a mailbox:

Default mailbox: INBOX
Parameters: mailbox, account, limit (default: 25), filter (unread, flagged, all)

Get Message

Use mail with action get to get a single message with full body content:

Required: id (RFC 2822 message ID)
Optional: mailbox, account (hints for faster lookup)
Optional: format (plain default, or markdown for HTML-to-markdown conversion)

Search Messages

Use mail with action search to find messages by subject, sender, or content:

Required: query (search term)
Optional: field (subject, sender, content, all), mailbox, account, limit, since (ISO 8601 date)

Send Message

Use mail with action send to send an email through Mail.app:

Required: to (array of recipient addresses), subject (email subject), body (plain text body)
Optional: cc, bcc, from (sender address for account selection)
Uses AppleScript to compose and send via Mail.app's outgoing message

Reply to Message

Use mail with action reply to reply to a message with proper threading:

Required: id (RFC 2822 message ID), body (reply text)
Optional: mailbox, account (hints for faster lookup)
Uses Mail.app's reply verb which sets In-Reply-To, References headers, and quotes the original

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
