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.

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 5.1 | $0.00066 | $0.03551 |
| Opus 5 | $0.00033 | $0.01775 |
| Sonnet 5 | $0.00013 | $0.00710 |
| Haiku 4.5 | $0.00007 | $0.00355 |
Grade A, and why
apple-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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 324 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Apple Mail (Read Only)
Read email two ways: Mail.app AppleScript for live state and attachments, and
ripgrep over the on-disk .emlx files for searching large archives.
No sending or modifying emails.
Prerequisites
AppleScript path:
- Mail.app running and logged in
- Automation permissions granted (System Settings → Privacy & Security → Automation → Terminal/Claude Code → Mail)
- If first access attempt times out, ask user to check for macOS permission dialog
Archive-search path: Full Disk Access for the calling terminal app (System Settings → Privacy & Security → Full Disk Access). Mail.app need not be running.
Reliability: always wrap osascript with timeout + retry
Apple Mail's AppleScript bridge hangs intermittently — sometimes for minutes — even on simple queries. The AppleScript-internal with timeout of N seconds does NOT kill a wedged osascript process. Always wrap calls with shell-level timeout and retry on failure.
Pattern:
# Run osascript with 15s shell timeout, retry up to 3 times with 2s backoff.
mail_query() {
local script="$1" attempt
for attempt in 1 2 3; do
result=$(timeout 15 osascript -e "$script" 2>&1) && { echo "$result"; return 0; }
sleep 2
done
echo "ERROR: Mail query failed after 3 attempts" >&2
return 1
}
# Usage:
mail_query 'tell application "Mail" to count (messages of inbox whose read status is false)'
Reasonable defaults: 15s timeout, 3 retries, 2s sleep. Bump the timeout for messages of every mailbox (cross-account searches) to 60s. If all 3 retries fail, report the failure and move on — never block a briefing on Mail.
Account & Machine Context
See docs/email-accounts.md for which accounts are configured on which machines.
Commands
List accounts
osascript -e 'tell application "Mail" to get name of every account'
Count unread messages
osascript -e 'tell application "Mail" to count (messages of inbox whose read status is false)'
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

apple-mail is a skill published in the GitHub repository eins78/agent-skills (2 stars, last pushed 2d ago), licensed MIT. It adds 66 tokens to every session and 3,551 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
