/triage-inbox — Academic Inbox + Calendar Triage

Turn a noisy academic inbox into a short, decision-ready digest. Fetch recent mail and calendar context through the session's MCP servers (Gmail / Google Calendar), classify each thread into the categories an academic actually acts on, and propose one action per thread — always human-gated. The companion artifact is a running referee-obligations tracker so you never silently overcommit to reviews.

Core principle: this skill reads, classifies, and proposes. It drafts; it never sends, accepts, declines, or books anything without you. That boundary is what makes it safe to run unattended as a /schedule routine.

When to use

• Weekly / daily sweep — "what landed that needs a decision?" without reading every thread yourself.
• As a scheduled routine — wired to /schedule to run each morning and leave a digest waiting.
• Referee-load management — keep an honest count of outstanding reviews against a standing cap before you say yes to one more.
• R&R / editor deadline capture — turn "minor revision due in 6 weeks" buried in an email into a calendar hold proposal.

When NOT to use

• To actually send a reply, accept an invite, or book an event — this skill stops at proposals. You confirm and execute.
• To handoff a project to a co-author — that's /coauthor-brief.
• To draft the R&R response document itself — that's /respond-to-referees.

Phases

Phase 0 — Pre-flight (MCP check, window, referee cap)

1. Confirm MCP access. This skill reaches mail/calendar only through the session's MCP tools (Gmail search/read, Google Calendar list/suggest). They are session-scoped — in a headless claude -p or cron run they may be absent. Probe once (e.g. list labels / list calendars). If unavailable, degrade gracefully: emit a tracker-only digest from the on-disk tracker (Phase 3) plus a one-line "MCP servers not reachable in this run — skipped fetch" note, and exit cleanly. Never fail the routine over a missing server.
2. Resolve the lookback window — --since (an ISO date or Ndays), else the timestamp of the last digest in quality_reports/inbox/, else default 7 days. Echo it back.
3. Set the referee-load cap — --cap if given, else read the standing cap from the tracker header, else default 3 concurrent reviews. This cap gates the recommendation in Phase 2, not your inbox.
4. Echo a one-line pre-flight before fetching: window, cap, calendar on/off (--no-calendar), dry-run on/off.

Phase 1 — Fetch + classify

1. Fetch recent threads via the MCP Gmail search tool over the window; if calendar is on, pull existing events/free-busy for the deadline-conflict check.

2. Classify each thread into exactly one bucket:

   Bucket	Signals
   Referee request	"invite you to review", journal/editor sender, manuscript ID, "would you be willing"
   R&R / editor correspondence	"revise and resubmit", "minor/major revision", decision letter, due-date language
   Co-author thread	known collaborator, shared-paper subject, "can you", "your section", attachment churn
   Seminar / conference invite	"invited talk", "submit by", CFP, "seminar series", scheduling polls
   Grant / admin deadline	funder name, "submission deadline", reporting/compliance, IRB/DUA renewals
   Noise	newsletters, receipts, auto-notifications — counted, not itemized

3. Capture per thread: sender, subject, a one-line gist, any explicit deadline, and the bucket.

Phase 2 — Propose one action per thread (NEVER auto-send)

For each non-noise thread, propose exactly one of:

• Draft reply — write a courteous draft for review. Do not send. If the Gmail MCP exposes a create-draft tool, you MAY stage a Gmail draft (which still requires the user to hit send) — otherwise inline the text in the digest.
• Calendar hold — for an R&R / grant / talk deadline, propose a hold (title, date, lead-time reminder). Surface conflicts against existing events. Propose only — booking is the user's click.
• Scaffold a referee project — for an accepted (or leaning-yes) referee request under the cap, offer to scaffold a referee project (dated folder + manuscript + notes template). Over the cap → recommend a polite decline draft instead, and say why ("4 reviews already open vs. cap of 3").
• Summarize + offer a brief — for a co-author thread, distill the asks and offer to generate a /coauthor-brief.
• Snooze — defer with a re-surface date; nothing else happens.

Hard gate: every outbound action (send, accept, decline, book, scaffold) waits for explicit user confirmation. Drafts and holds are proposals. Honor --dry-run by proposing without staging even drafts.

Phase 3 — Emit digest + update the obligations tracker

1. Digest → quality_reports/inbox/YYYY-MM-DD_triage.md (create the dir). Buckets ordered by urgency; each item is a one-liner + its proposed action. Noise is a count, not a list.
2. Referee-obligations tracker → quality_reports/inbox/referee-obligations.md (a persistent ledger, not dated). Append/refresh rows for any review accepted, declined, or completed this run; recompute open count vs. cap; flag overdue rows.

Output / report format

# Inbox Triage — YYYY-MM-DD   (window: last N days · referee cap: K)

## Needs a decision (M)
- **[R&R]** *J. of X* — minor revision, **due 2026-07-15**. → Propose calendar hold (−14d reminder); conflicts: none.
- **[Referee]** *Econometrica* — review request, manuscript 12-345. Open reviews 2/3 → under cap. → Offer to scaffold a referee project.
- **[Co-author]** A. Smith — "can you redo Table 3 with not-yet-treated controls?" → Summarized; offer `/coauthor-brief`.

## FYI / snoozed (P)
- **[Seminar]** Dept. brown-bag poll — snoozed to 2026-06-16.

## Noise: 24 threads (newsletters, receipts) — not itemized.

## Referee load: 2 open / cap 3  (see referee-obligations.md)

Plus the one-line chat summary: digest path, counts per bucket, open-reviews-vs-cap, and whether the MCP fetch ran or was skipped.

Exit behavior

• Normal run: write the digest, refresh the tracker, print the summary line. No mail sent, no event booked, no project scaffolded — those await your confirmation.
• MCP unavailable (headless/cron): tracker-only digest + "fetch skipped" note; exit 0. The routine must not error just because a session server is absent.
• Over the referee cap: still surface the request, but the proposed action is a decline draft with the count as rationale — never a silent scaffold.
• --dry-run: propose everything, stage nothing (not even a draft).

Flags

• --since <Ndays|date> — Lookback window. Default: the last digest's timestamp, else 7 days.
• --cap <N> — Standing concurrent-review cap that gates referee scaffolding. Default: the tracker header value, else 3.
• --no-calendar — Skip the Calendar MCP entirely; classify mail only, no holds proposed.
• --dry-run — Propose actions without staging anything (no Gmail drafts created).

Cross-references

• .claude/skills/coauthor-brief/SKILL.md — the handoff brief offered for co-author threads.
• .claude/skills/respond-to-referees/SKILL.md — drafts the R&R response document once a revision deadline surfaces here.
• /schedule — wire this skill into a cron routine; the human-gated design is what makes unattended runs safe.
• .claude/rules/orchestrator-protocol.md — the "no daemon, user/skill-initiated, human-in-the-loop" contract this skill honors for outbound actions.
• .claude/rules/confidential-data.md — never copy attachment contents, restricted data, or credentials into a digest that may be committed.

What this skill does NOT do

• Send, reply, accept, decline, or book. It drafts and proposes; you execute. No exceptions, including in scheduled runs.
• Auto-scaffold a referee project. It offers the scaffold; creating it waits for your yes and respects the cap.
• Run unattended with side effects. Outbound actions are always human-gated — the only thing a cron run writes is the digest and the tracker.
• Read or store message bodies wholesale. It extracts gists, deadlines, and senders; it does not archive email contents or attachment data into the repo.
• Reach mail/calendar without MCP. No direct IMAP/API credentials — everything goes through the session's MCP servers, and their absence degrades gracefully.
