What is inbox-triage?

An email-management workflow that reviews recent messages, classifies them, researches unfamiliar senders, recommends actions, and drafts replies without sending them. It uses a knowledge base created by a separate inbox-setup workflow.

Use it to process incoming email, identify messages needing attention, prepare reply drafts, and maintain email-related knowledge over repeated runs.

It reduces the manual work of sorting an inbox while keeping the final decision and sending of replies with the user.

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	$0.00204	$0.03326
Opus 5	$0.00102	$0.01663
Sonnet 5	$0.00041	$0.00665
Haiku 4.5	$0.00020	$0.00333

Security

Grade A, and why

inbox-triage 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 7d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/draft_safety_validator.py, scripts/kb_reader.py, scripts/search_window_calculator.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Inbox-Triage — Recurring Email Triage

Paired with inbox-setup. This skill consumes the 7-file knowledge base that inbox-setup writes at ${WORKSPACE}/Email/. The file contracts MUST match exactly. See references/kb_file_contract.md — this is the mirror of the setup-side contract, viewed from the read side.

Run on a recurring schedule (1–3x daily) or on demand. Classify recent emails, research new senders, generate decision recommendations, draft replies (NEVER SEND), deliver a clean report, and update the knowledge base with what was learned this run.

Prerequisites

Required reads at start (fail-fast if missing):

Core (required):

${WORKSPACE}/Email/email-taxonomy.md — classification + report preferences
${WORKSPACE}/Email/email-patterns.md — voice, persona, templates, hard rules

Optional core (read if exists):

${WORKSPACE}/Email/evaluation-framework.md
${WORKSPACE}/Email/rate-card.md

Evolving (read AND update every run):

${WORKSPACE}/Email/blocklist.md
${WORKSPACE}/Email/tracker.md

Output:

${WORKSPACE}/Email/triage-log/<YYYY-MM-DD>-<run-label>.md — per-run log

If any core required file is missing → halt, direct user to run inbox-setup first. Use scripts/kb_reader.py to perform the read + validation.

DRAFTS ONLY — Never Send

This skill creates drafts. It NEVER sends.

This is the safety property that makes the skill safe to run automatically. Stated multiple times in this skill body. Non-negotiable.

The scripts/draft_safety_validator.py enforces it post-run. Any send-shaped tool call in the action log fails validation. See references/drafts_only_safety.md for the full discipline canon.

What ships with it

Changes

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.
