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 | $0.00019 | $0.01281 |
| Opus 5 | $0.00010 | $0.00641 |
| Sonnet 5 | $0.00004 | $0.00256 |
| Haiku 4.5 | $0.00002 | $0.00128 |
Grade A, and why
email-management 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 10d 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 — 172 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Email Management SOP
Goal
Process email systematically so the inbox stays clear, nothing falls through the cracks, and email doesn't bleed into deep work time.
Core Principle: 4D Triage
For every email, apply exactly one action immediately:
| Decision | When | Action |
|---|---|---|
| Delete | Newsletters, FYIs, CC'd you unnecessarily | Archive or delete immediately |
| Delegate | Someone else should own this | Forward with clear ask, move to "Waiting" |
| Do | Takes under 2 minutes | Reply now, then archive |
| Defer | Needs thought, research, or specific time | Move to task manager or snooze |
Rule: Never leave an email in the inbox after making a decision.
Batch Processing Schedule
Do not check email continuously. Batch to 2-3 times per day:
| Time | Purpose |
|---|---|
| Morning (9am) | Full triage — clear inbox, action urgent items |
| Midday (12-1pm) | Quick scan — replies only, no new tasks |
| EOD (5pm) | Final sweep — defer anything not done today |
Turn off push notifications. Check on your schedule.
Folder / Label Taxonomy
Inbox ← Only unprocessed email lives here
├── Action ← Needs reply or action from you
├── Waiting ← Delegated; waiting on others
├── Reference/
│ ├── Finance ← Invoices, receipts, contracts
│ ├── HR ← Offer letters, benefits, onboarding
│ ├── Projects/ ← One subfolder per active project
│ └── Personal ← Non-work reference
└── Archive ← Everything else (searchable, not filed)
Key rule: Archive aggressively. The search bar is more reliable than folder filing.
Email Rules / Filters to Set Up
Automate triage with filters (Gmail, Outlook, Apple Mail all support this):
Rule: Newsletter/marketing
FROM contains: unsubscribe | noreply | newsletter | digest
→ Skip inbox, label "Newsletter", mark read
Rule: CC'd only
TO does not contain: [your email]
→ Skip inbox, label "CC", mark read
Rule: GitHub/Linear/Jira notifications
FROM: [email protected] | linear.app | jira
→ Skip inbox, label "Dev Tools", mark read
Rule: Calendar invites
Contains: .ics attachment OR subject contains "invitation"
→ Keep in inbox (needs action)
Rule: Receipts
FROM: receipt | invoice | order | billing
→ Label "Finance/Receipts", mark read
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.
