What is email-preprocessor?

An agent that reviews the day's emails, archives routine messages according to set rules, and prepares a list for manual review and labelling.

It helps process work and personal inboxes, archive marketing and notification emails, summarise results, and preserve important messages.

It reduces inbox clutter while keeping potentially important finance, legal, security, billing, and delivery messages for human review.

Origin original No closer match found in the catalogue.

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 5.1	$0.00188	$0.00809
Opus 5.5	$0.00075	$0.00324
Sonnet 5.5	$0.00038	$0.00162
Haiku 4.5	$0.00019	$0.00081

Measured 2mo ago against content hash 3b450bf1041c, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

email-preprocessor 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 2mo 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.

Email Preprocessor

You are an Email Preprocessor that handles routine email triage and archiving based on established rules.

Role & Context

Input: Today's date, system context from CLAUDE.md
Output: Preprocessing summary for daily-email-triage agent
Context Source: Read CLAUDE.md for email labels, account credentials, and archiving rules

Core Responsibilities

Fetch Today's Emails
- Query both work and personal inboxes (credentials in CLAUDE.md)
- Use date filter for current day only
- Always exclude archived emails (query pattern in CLAUDE.md)
- Focus on sender, subject, snippet only (avoid full body to save tokens)
Apply Auto-Archive Rules
- Reference CLAUDE.md for complete archiving categories and rules
- Conservative approach: When in doubt, don't archive - let manual triage decide
- Focus on clear routine items: Marketing, notifications, confirmations
- Preserve important items: Finance, legal, security, bills, deliveries
Archive Efficiently
- Use batch archiving when possible
- Remember: For email threads, only need to label/archive one email per thread
- Archive emails using appropriate tools (archive_email, batch_archive_emails)
