What is cowork-inbox-triage?

An inbox-management routine for Microsoft 365 or Gmail that sorts unread email, drafts replies for approval, highlights messages needing a decision, and schedules follow-up checks.

Use it for daily email triage, reply drafting, follow-up tracking, and handling newsletters, notifications, and other noise.

It reduces a large unread inbox to clear categories and a short list of actions without sending messages automatically.

SkillSpector: 1 finding, up to medium

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

medium Excessive Agency · line 10
Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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	$0.00060	$0.00743
Opus 5	$0.00030	$0.00371
Sonnet 5	$0.00012	$0.00149
Haiku 4.5	$0.00006	$0.00074

Security

Grade A, and why

cowork-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 12d 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 — 48 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Cowork Inbox Triage

Work an inbox the way a good chief of staff does: everything gets a disposition, nothing gets sent without approval, and the owner ends the run with a short list of real decisions instead of 80 unread threads. Uses the connected mail tools (Microsoft 365 or Gmail MCP connectors) for reading, labeling, and drafting.

Setup

On first run, learn the owner's voice: read 10-15 sent replies and note greeting style, sign-off, sentence length, and formality. Store the profile in the conversation and reuse it for every draft. Ask once which categories matter (default set below) and what the auto-archive rules are.

Workflow

Sweep. Pull unread and flagged threads from the last cycle (default: 24 hours). Group by thread, not message.
Classify every thread into exactly one bucket:
- NEEDS DECISION -- only the owner can answer (pricing, commitments, personnel)
- DRAFT READY -- routine reply Claude can write for approval
- WAITING ON THEM -- owner already replied; schedule a follow-up check
- FYI -- no response needed; summarize in the digest
- NOISE -- newsletters, notifications, cold outreach; label/archive per the standing rules
Draft. For every DRAFT READY thread, write the reply in the owner's voice as a draft -- never send. Keep drafts shorter than the email being answered.
Follow-ups. For WAITING ON THEM threads past their expected response window (default 3 business days), draft a polite bump. For threads with dates in them, propose calendar holds via the calendar write tools.
Digest. Post one summary: decisions needed (with one-line context and a recommended answer each), drafts awaiting approval, follow-ups queued, and a one-line count of what was archived.

Rules

Never send email. Create drafts only; the human sends.
Never archive anything that mentions money, contracts, legal matters, or a specific person's problem -- misclassified noise is recoverable, a missed client email is not.
A recommended answer accompanies every NEEDS DECISION item. Surfacing a question without a recommendation is half the job.
Quote the sender's actual ask in the digest -- do not paraphrase requests into vagueness.
Respect confidentiality: HR, health, and personal matters get flagged privately, never summarized in a shared channel.
If the connector lacks write scope, degrade gracefully: produce the digest and paste-ready reply texts instead of drafts.

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.
