Hey

/hey - HEY Email Workflow Command

CLI for HEY: mailboxes, labels, collections, email threads, contacts, replies, compose, calendars, todos, habits, time tracking, and journal entries.

Agent Invariants

MUST follow these rules:

1. Choose the right structured output — use --jq '<expression>' to filter or extract fields and --json for the full response. Never pipe to an external jq; --jq is built in and implies --json.
2. Reuse stored authentication — run the requested data command; it uses stored credentials and refreshes expiring OAuth tokens automatically. If it returns an auth error, report the task as blocked. Use hey auth status --json when an explicit authentication check is needed. Never run hey auth login unattended; use it only for interactive recovery with the user present.
3. HTML output is available via --html for commands that return HTML content
4. Linked mail accounts share one login — use hey account list --json, then --account <id|all> when a task must target one account
5. Local HEY configuration requires human trust — never run hey config trust-local without the user's explicit approval

Output Filtering

--jq filters the full JSON success envelope, so result data is under .data. String results print as plain text; objects and arrays print as formatted JSON. Use --quiet --jq when the expression should run against result data directly. Errors retain their complete structured envelope. Commands with dedicated raw output (auth token, completion, skill, tui, and --version) reject --jq.

hey box list --jq '.data[] | {id, name}'
hey search "quarterly planning" --jq '.data[].id'
hey box list --quiet --jq '.[].name'

An empty result is an empty array rather than null, so .data[] is safe to run against a listing that found nothing.

For the two commonest shapes there is no need for an expression at all: --ids-only prints one ID per line and --count prints a bare number, both on stdout with any pagination notice on stderr. Both need list data, so they work on hey box list, hey box view, hey label list, hey label view, hey collection list, hey collection view, hey workflow list, hey workflow view, hey clip list, hey snippet list, hey draft list, hey search, hey contact list, hey screener list, hey screener history, hey calendar list, hey event list, hey event day, hey event week, hey todo list, hey habit list, hey timetrack list, hey journal list and hey attachment list. On hey box view they count and list its postings, not the box itself.

Resource Reference

Email - Boxes

hey box list --json                          # List all mailboxes
hey box view imbox --json                    # List emails in Imbox (by name)
hey box view 123 --json                      # List emails in box (by ID)
hey box view imbox --page next-cursor --json # Continue from an earlier listing

Box names: imbox, feedbox, trailbox, asidebox, laterbox, bubblebox

Response format: hey box view --json returns the box itself — id, kind, name, app_url, next_history_url, next_page — with a postings array of the email threads in it. Each posting has: id (box item ID), topic_id (thread ID), name (subject), seen (read status), created_at, contacts, summary, app_url, visible_entry_count. Use id for hey seen, hey unseen, hey move, hey label add, hey label remove, hey trash, hey spam, hey ignore, and hey stop-ignoring, and topic_id for hey thread read, hey reply, hey forward, hey share and hey attachment list. A box item id passed to hey thread read answers not_found, and so does a topic_id passed to hey move.

A posting that bundles a contact's mail into one row can omit topic_id: a bundle names its sender rather than a thread, and its name joins the bundled subjects with •. A bundle that does carry a topic_id opens as that thread — its one unseen thread — and hey threads reads it as usual. For a bundle without one, never substitute the box item id (hey threads <id> answers not_found); there is no command that lists the threads inside a bundle, so run hey contacts unbundle <contact_id> — the contact is in the posting's contacts — to list that sender's mail as separate rows, or direct the user to open the bundle in HEY.

next_page is the cursor --page takes, and it is the cursor inside next_history_url — --page accepts either. --all reads to the end instead.

--ids-only and --count work here too, and answer for the postings: one box item ID per line, or how many threads were read.

Email - Labels

hey label list --json                         # List labels and stable IDs
hey label view 789 --all --json                # List every thread with a label
hey label add 12345 --to 789                   # Add an existing label
hey label create "Travel receipts" 12345       # Create and add a label
hey label remove 12345 --from 789              # Remove one label
hey label remove 12345 --from all              # Remove every label

Label mutations take box item IDs from hey box view, hey label view, or active hey search results. Label IDs come from hey label list. hey label view returns next_page and total_count; pass --page <next_page> to continue or --all to fetch every page. HEY creates a label while adding it to at least one thread, so label create requires one or more thread item IDs.

Email - Collections

hey collection list --json                                 # List collections and stable IDs
hey collection view 321 --all --json                        # List every thread in a collection
hey collection create "Kitchen remodel" --summary "Plans and decisions"
hey collection update 321 --name "Kitchen renovation"
hey collection add 987 --to 321                             # Add a topic ID
hey collection remove 987 --from 321                        # Remove a topic ID

Collection IDs come from hey collection list. hey collection view returns posting id, thread topic_id, next_page, and total_count; pass --page <next_page> to continue or --all to fetch every page. Collection membership commands take topic_id. Creating a collection confirms the mutation, and listing collections provides its ID for later commands.

Email - Set Aside groups

hey set-aside view --all --json                # Set Aside threads, each with box_group_id when grouped
hey set-aside group list --json                # Groups with thread_count
hey set-aside group view 42 --all --json       # Threads in one group; pages like a box
hey set-aside group create 12345 67890         # New group from box item IDs; answers the group id
hey set-aside group add 12345 --to 42          # File threads into a group (moves them out of another)
hey set-aside group remove 12345               # Ungroup; threads stay in Set Aside
hey set-aside group delete 42                  # Dissolve the group; its threads go to Previously Seen

Groups have no name in HEY: a group is its ID and the threads in it. Group commands take posting id values (box item IDs), not topic_id. HEY's group index answers IDs alone, so group list reads each group once for its count; group view returns next_page and total_count and takes --page and --all. HEY removes a group itself once its last thread leaves, so group view or group delete on it answers not_found. group create moves threads into Set Aside if they are in another box. To clear an overflowing Set Aside without losing threads, prefer group create/group add over group delete: deleting a group moves its threads to Previously Seen in the Imbox.

Email - Search

hey search "quarterly planning" --json         # Free-text search
hey search --from jane@example.com --date last_30_days --json  # Refined search
hey search --subject invoice --attachment pdfs --all --json    # Search up to 100 pages
hey search filters --json                      # Available box, date, label, and attachment values

Search refinements are --required, --any, --none, --exact, --from, --to, --subject, --date, --in, --label, and --attachment. --page selects one result page; --all fetches up to 100 pages from that point onward. When the cap is reached, the response notice provides the next --page value for continuation.

--in, --date, --label and --attachment accept only the values hey search filters lists: boxes are imbox, feed, papertrail, trash; dates are last_7_days, last_30_days, last_90_days or a four-digit year; attachment kinds are any, images, pdfs, calendar_invites, documents, spreadsheets, presentations, media, zip_files. The kinds are plural — --attachment pdfs, not pdf. An unrecognized --in, --date or --attachment is refused as a usage error naming the values it accepts, before anything is sent; --label is not checked, so read hey search filters when unsure of a label.

Response format: data contains one item per matching thread. Each result has id (box item ID for organization actions), topic_id (thread ID for hey thread read, hey reply, and hey forward), subject, updated_at, and messages containing the matching message IDs, senders, dates, and summaries. A result can omit id when the thread has no active box item.

Contacts

hey contact list --json                       # List contacts
hey contact list --page 2 --json              # List another page
hey contact show 12345 --json                 # View details, aliases, and private note
hey contact add --name "Jane Doe" --email jane@example.com
hey contact add --name "Jane Doe" --email jane@example.com --alias jane.doe@example.org
hey contact update 12345 --name "Jane Dawson"
hey contact update 12345 --alias=              # Clear aliases
hey contact hide 12345                         # Hide from lists and autocomplete
hey contact show-again 12345                   # Reverse hiding
hey contact bundle 12345                       # Group this contact's mail into one row
hey contact unbundle 12345                     # List this contact's mail separately
hey contact note show 12345 --json
hey contact note set 12345 "Prefers email"
echo "Multiline private note" | hey contact note set 12345
hey contact note delete 12345

hey contact list returns contact IDs, names, email addresses, and update timestamps. hey contact show adds aliases, screening status, and the private note. Contact updates preserve omitted fields. Supplying --alias replaces the complete alias list, and --alias= clears it.

HEY hides contacts instead of permanently deleting them. A hidden contact leaves contact lists, autocomplete, and search results while remaining available by ID; show-again reverses the action. Bundling groups a contact's mail into one row without merging or deleting the underlying threads; unbundle lists those threads separately again. HEY applies bundling when the contact's current delivery setting supports bundles. Contact notes are private and support positional content, --note, stdin, or $EDITOR. Deleting a note leaves the contact unchanged.

Email - Threads

hey thread read <topic_id> --json                 # Read full email thread
hey thread read <topic_id> --html                 # Read with raw HTML content
hey share <thread_id>                         # Get a sharing link
hey unshare <thread_id>                       # Turn off the sharing link

hey thread read returns every entry in the thread, oldest first. Each entry's body is Markdown, converted from HEY's Trix HTML at the edge, so headings, lists, quotes, tables and code survive and links keep their URLs — read it as structure rather than as flattened text. --html returns the original HTML instead. There is no recipients field on an entry; use hey reply, which works the addressing out itself.

hey share returns a URL that shows the entire thread and future emails or replies sent to it. Anyone with the link can open it. hey unshare turns off the sharing link.

ID note: Every email thread has two IDs: an id (its box item ID) and a topic_id (its thread ID). hey seen, hey unseen, hey move, hey label add, hey label remove, hey trash, hey spam, hey ignore, and hey stop-ignoring expect id. hey thread read, hey share, hey unshare, hey attachment list, hey reply, hey forward, hey collection add, and hey collection remove expect topic_id. Passing the wrong one answers not_found, not a redirect.

hey box view --json, hey label view --json, hey collection view --json and hey search --json all carry both — except a bundle posting, which can omit topic_id (see the Boxes section).

Email - Attachments

hey attachment list <topic_id> --json               # List files in every message
hey attachment save 67890:1                    # Save using a returned ID
hey attachment save 67890:1 --output ./reports # Save into a directory
hey attachment save 67890:1 --output ./report.pdf --force

Direct attachment IDs combine the message ID and position, so 67890:1 identifies the first direct attachment in message 67890. Named downloadable files inside embedded HTML, including named inline images, use opaque IDs scoped to their message. Pass the ID returned by hey attachment list to hey attachment save. Saving uses the original filename unless --output names a destination. Existing files are preserved unless --force is set.

Email - Reply, Forward & Compose

hey reply <topic_id> -m "Friday works for me — I'll send an agenda."  # Inline message
hey reply <topic_id>                          # Reply via $EDITOR
hey reply <topic_id> -m "Here is the wiring diagram." --attach ./diagram.png
hey forward <topic_id> --to alice@example.com                 # Forward the latest message
hey forward <topic_id> --to alice@example.com -m "Please review before Thursday."
hey compose --to alice@example.com --subject "Lunch plans"    # Body from $EDITOR
hey compose --to alice@example.com --subject "Lunch plans" -m "Are you free Friday?"
hey compose --to alice@example.com --subject "Q3 revenue report" --attach ./report.pdf  # Attachment-only message
hey compose --to alice@example.com --subject "Q3 revenue report" -m "The numbers are attached." --attach ./report.pdf --attach ./chart.png
hey compose --to alice@example.com --cc bob@example.com --bcc carol@example.org --subject "Kitchen remodel timeline" -m "Cabinets land the week of the 14th."
hey compose --thread-id 12345 -m "Confirmed — see you then."  # Reply into an existing thread (no subject: it carries the thread's)
hey compose --to alice@example.com --subject "Sprint recap" -m "We **shipped** the pagination fix."
hey compose --to alice@example.com --subject "Newsletter draft" --message-html "<h1>March</h1><p>What we shipped.</p>"

hey reply answers the thread's latest entry. HEY addresses the reply the way its own web app does: everyone that entry was addressed to, plus whoever wrote it, on the To line. A reply HEY cannot address is saved as a draft rather than sent, so the command fails rather than guessing when it cannot work out the recipients.

Everything you send is Markdown by default — -m, --content, --note, positional content, stdin, and $EDITOR alike — and is converted to rich text on the way out. To send raw HTML instead, use the flag's HTML twin: --message-html on compose, reply, forward, and bulk-reply send; --content-html on journal write and snippet create/update; --note-html on contacts note set. Each pair is mutually exclusive. A fenced code block's language (```ruby) survives the conversion, and HEY's web app syntax-highlights it.

Email - The Screener

hey screener list --json                      # Who is waiting to be screened
hey screener list --count                     # Just the number waiting (cheap)
hey screener approve 91                       # Let a sender through, into the Imbox
hey screener approve 91 --box "The Feed"      # Let them through, into another box
hey screener approve 91 --seen                # Deliver what they sent, already read
hey screener deny 91 92                       # Turn several senders away
hey screener deny 91 --spam                   # Turn away and train the spam filter
hey screener history --json                   # Who has already been decided
hey screener clear                            # Empty the queue without deciding

The Screener is where first-time senders wait. hey screener list returns clearance IDs — not contact IDs and not posting IDs — with the sender, what they sent, and a topic_id for reading the thread before deciding. --count is a far cheaper request than the queue and prints a bare number.

Approving delivers everything that sender has waiting; denying hides it. Either is reversible with the opposite command. --box and --seen apply to one sender at a time; several IDs go through HEY's bulk endpoint, which takes neither. --spam also trains HEY's filter, which is harder to undo than a plain deny. hey screener clear decides nothing — those senders are asked about again on their next email.

Email - Bulk reply

hey bulk-reply preview 12345 67890 --json     # Read-only: threads and exact recipients
hey bulk-reply send 12345 67890 -m "Thanks for the update — noted."
hey bulk-reply undo 98765                     # Recall a delayed bulk reply

Takes posting IDs, which must be positive and unique. Always run preview first — it resolves each posting to the entry a reply would answer and shows the exact To/CC/BCC, so the blast radius is visible before anything sends. send resolves the selection again and skips threads with no replyable entry, then returns the reply count, delivery ID, delayed state, undo URL and undo command. undo works only while HEY's undo window is open.

Email - Seen/Unseen

hey seen 12345                                # Mark a thread as seen
hey seen 12345 67890                          # Mark multiple threads as seen
hey unseen 12345                              # Mark a thread as unseen
hey unseen 12345 67890                        # Mark multiple threads as unseen

Takes box item IDs (the id field from hey box view output).

Email - Moving Threads

hey move 12345 --to feed                      # Move one thread
hey move 12345 67890 --to "paper trail"       # Move multiple threads
hey move 12345 67890 --to imbox               # Remove Reply Later from threads

Takes box item IDs (the id field from hey box view --json). --to accepts a box name, kind, or ID. Supported destinations are Imbox, The Feed, Set Aside, Reply Later, and Paper Trail. Reply Later is a box, not an independent flag: moving a Reply Later thread to Imbox removes Reply Later, preserves its seen state, and leaves a seen thread in Previously Seen. It does not return the thread to the box it occupied before Reply Later. Bubble Up goes through hey bubble instead.

Email - Bubble Up

hey bubble up 12345 --now                     # Bubble a thread up to the top of the Imbox
hey bubble up 12345 67890 --now               # Bubble multiple threads up
hey bubble up 12345 --on 2026-09-04           # Bubble a thread up on a date
hey bubble up 12345 --tomorrow                # Bubble a thread up tomorrow morning
hey bubble up 12345 --weekend                 # Bubble a thread up Saturday morning
hey bubble up 12345 --next-week               # Bubble a thread up Monday morning
hey bubble list                               # List bubbled-up and scheduled threads
hey bubble pop 12345                          # Cancel a thread's bubble-up

Takes box item IDs (the id field from hey box view --json). hey bubble up requires exactly one of --now, --on, --tomorrow, --weekend, and --next-week. --on takes a YYYY-MM-DD date; HEY bubbles the threads up at its morning hour of that day, or at its evening hour (18:00) when the date is today.

hey bubble list --json answers two buckets: bubbled_up, the threads back in the Imbox after bubbling up, and scheduled, the threads waiting in Bubble Up — each scheduled row carries bubble_up_schedule.bubble_up_at, and surprise_me when HEY picked the time. Use id with hey bubble pop, topic_id with hey thread read.

Email - Trash and Spam

hey trash 12345                               # Move one thread to Trash
hey trash 12345 67890                         # Move multiple threads to Trash
hey spam 12345                                # Mark one thread as spam
hey spam 12345 67890                          # Mark multiple threads as spam

Takes box item IDs (the id field from hey box view --json). Trashing a shared thread removes your access instead of deleting it for everyone. Marking a thread as spam moves it to Spam and trains HEY's filters.

Email - Ignoring Threads

hey ignore 12345                              # Ignore one thread
hey ignore 12345 67890                        # Ignore multiple threads
hey stop-ignoring 12345                       # Stop ignoring one thread
hey stop-ignoring 12345 67890                 # Stop ignoring multiple threads

Takes box item IDs (the id field from hey box view --json). Ignored threads remain in their box; new replies do not bring them back to your attention. hey stop-ignoring reverses the action.

Email - Watching for changes

hey watch                         # Follow every box until interrupted
hey watch --box imbox             # Report one box's changes (repeatable, by name or ID); every box is followed
hey watch --events added,deleted  # Only these changes (added, updated, deleted, new, resync)
hey watch --box imbox --events new  # New mail only: unseen, unmuted, active since the watch began
hey watch --box imbox --events new --exit-on-first  # Block until new mail lands, print it, exit
hey watch --exit-on-first         # Wait for one change of any kind, print it, exit
hey watch --timeout 30m           # Give up waiting after a while
hey watch --since 2026-03-15      # Report changes since then first, then follow
hey watch --run-sync ./triage.sh  # Run a command per change instead of printing

Long-running, and driven by a websocket rather than polling — never poll hey box in a loop when this will do. Writes one JSON object per changed posting to stdout, one per line, instead of the usual envelope: {"change": "added", "at": ..., "box": {"id", "kind", "name"}, "posting_id": ..., "thread_id": ..., "new": true|false, "posting": {...}}. Use thread_id with hey thread read. new is on every added and updated line and says whether the posting is new mail — unseen, not muted, and active since the watch last saw the thread, or since the watch began for a thread it has not seen; the backlog a watch starts with is never new, nor is reading, muting or moving a thread, and a reply on a known thread is. --events new selects the new ones, alone or in a union with the other three. A deleted posting carries no posting, thread_id or new. Three more lines describe the watch itself: {"change": "ready"} once every box is caught up and the subscription is live (again after every reconnect's catch-up), {"change": "disconnected"} when the connection drops, and {"change": "resync", "box": {...}} when a box changed more than the feed can list and the watch skipped ahead — re-read that box. A resync is an event of its own: reported by default (--run-* scripts run for it, --exit-on-first counts it) and left out by --events new, so a script for new mail never runs on one; ready and disconnected are written to stdout only and carry no box.

To drive a command per change, choose one of two behaviours — passing both is an error. --run-async spawns the command and moves on, so a slow one never holds up the watch and two can overlap; --run-sync waits for each and runs them in order. Both get the JSON on stdin and the fields as HEY_CHANGE, HEY_AT, HEY_BOX_ID, HEY_BOX_KIND, HEY_BOX_NAME, HEY_POSTING_ID and HEY_THREAD_ID — plus HEY_NEW=1 for new mail, HEY_NEW=0 otherwise — and both take over stdout.

Drafts

hey compose --subject "Board update" -m "Numbers to follow." --draft   # save instead of sending; answers the draft id
hey reply <topic_id> -m "Drafting this." --draft  # save a reply draft, addressed like a real reply
hey draft list --json                             # List drafts; --all and --page follow the next_page cursor
hey draft show <draft_id> --json                  # The draft's editable state; body is Markdown
hey draft edit <draft_id> --to alice@example.com  # Each flag replaces its field; omitted flags keep the draft's
hey draft send <draft_id>                         # Deliver now (through HEY's undo window)
hey draft delete <draft_id> [<draft_id>...]       # Trash drafts

This is the review-before-send lane: an agent prepares the email as a draft, a person reviews and sends it from any HEY app (or the agent sends it later with hey draft send). A draft needs no recipients until it is sent; --draft on hey compose lifts the recipient requirement.

An edit is a revision, not a patch. The CLI reads the draft first and resends the whole of it, so an omitted flag keeps that field. --to/--cc/--bcc replace their entire recipient kind; an explicit empty value (--cc "") clears it. Any scheduled delivery is preserved through edits.

Scheduled deliveries. Scheduling is done in a HEY app for now; the CLI cannot set a schedule (HEY's API cannot yet name an exact instant). A draft scheduled in an app stays in hey draft list until it goes out, hey draft show reports scheduled_delivery_at in UTC like every HEY timestamp, an edit preserves the schedule untouched — refusing the rare schedule it could not keep exact rather than moving it — and hey draft delete cancels it entirely.

Calendars

hey calendar list --json                          # List calendars (returns array of {id, name, kind})

Everything a calendar holds is a recording, and each kind has its own command: hey event, hey todo, hey journal, hey habit, hey timetrack. Those that read a calendar's window — hey event list, hey todo list, hey journal list — share --calendar, --starts-on, --ends-on, --limit and --all. Both dates want YYYY-MM-DD; an unreadable one, or an --ends-on before --starts-on, is a usage error rather than an empty result. Naming only --starts-on moves the whole window rather than reading up to the default end.

Events

hey event list --json                        # Every calendar, from today onward
hey event list --calendar 123 --starts-on 2026-01-01 --ends-on 2026-01-31 --json
hey event day --json                         # Today as HEY draws it, recurrences expanded
hey event day 2026-09-02 --json              # One day
hey event week 2026-09-02 --json             # The week that day falls in
hey event add "Design review" --starts-on 2026-09-02 --start-time 14:00 --end-time 15:00
hey event add "Sarah's birthday" --starts-on 2026-09-02   # No time given, so all day
hey event add "Standup" --start-time 09:15 --repeat every_weekday --remind 10m
hey event edit 4821 --title "Design review (moved)"
hey event delete 4821

Without --calendar, list reads every calendar and add files on the first one that accepts events — the personal calendar is in the list HEY serves but refuses them. A repeating event lists once as its series, not once per day.

"What's on my schedule today?" is hey event day, not list. A day or a week is the span as HEY draws it: a repeating event is expanded into the occurrences inside it, each carrying that day's own times and an occurrence_id, with its id still naming the series that edit and delete take. The period covers the calendars switched on in HEY, so day and week take no --calendar — only --limit and --all.

Response format: a flat array of events. Each has id, title, starts_at, ends_at, all_day, recurring, starts_at_time_zone and calendar; one being edited also carries description (the notes, as plain text), location, url, attached_entry and reminders. --count and --ids-only read that array directly.

Editing is a replacement, not a patch. hey event edit reads the event first and sends back the notes, location, link, attached email, reminders and time zones it is not changing, because HEY clears whatever a write omits. Two things still cannot survive it: notes come back as plain text, so their formatting is flattened, and a countdown is not served at all, so an edit removes one unless --countdown names it again. An event that cannot be read is refused rather than written blind — pass the day it starts (hey event edit 4821 2026-09-02) or --calendar to narrow the search.

An event with no --start-time is all-day; a --start-time with no --end-time runs an hour. Clock times are read in --time-zone, defaulting to the machine's zone.

Todos

hey todo list --json                          # List all todos
hey todo add "Draft the quarterly report"     # Add a todo
hey todo add "Book the venue" --date 2026-09-04  # With
