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 | $0.00112 | $0.00400 |
| Opus 5 | $0.00056 | $0.00200 |
| Sonnet 5 | $0.00022 | $0.00080 |
| Haiku 4.5 | $0.00011 | $0.00040 |
Grade A, and why
backup-mailbox 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 3d 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.
What it actually says
Back up a single Mail.app account to a pristine, restorable folder of .emlx messages plus mailbox metadata.
Use Bash (one call, then stop):
/Users/esaruoho/work/apple/bin/backup-mailbox $ARGUMENTS
The script:
- Launches Mail.app if it isn't running (its scripting suite only responds live).
- Resolves
<account>(email, AppleScript name, or V10 UUID) → V10 directory. - Quits Mail.app so no
.emlxis mid-write during the copy. rsync -ainto~/Backups/mail-<prefix>-YYYY-MM-DD/.- Renames every top-level
*.mboxwith the prefix (INBOX.mbox→<prefix>-inbox.mbox,[Gmail].mbox→<prefix>-gmail.mbox, etc.). - Counts
.emlxfiles in source vs backup and reports the byte total.
Print the script output verbatim. Do not summarize or moralize.
Apple-native: Python stdlib + osascript + rsync only. Documented at wiki/concepts/mail-backup.md.
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.
