Mentions Guide

Link to people, projects, workunits, and tasks inline as you write. Mentions turn typing into structured links — and notify the right person automatically.

What are Mentions?

A mention is an inline reference to a person, project, workunit, or task. When you type one, it renders as a clickable chip instead of plain text — and if you mentioned a teammate, they get a notification with a link straight to where they were named.

Mentions work in every text surface where you collaborate: workunit descriptions, task comments, signals, chat, asset notes, knowledge content, context atoms, calendar events. One pattern, everywhere.

Without mentions
Hey Alice, I pushed the fix for the cache layer task in the Ship the rocket workunit. Can you review when you get a chance?
No notification, no links, no context.
With mentions
Hey @Alice Cooper, I pushed the fix for #Ship the rocket: Refactor cache layer . Can you review when you get a chance?
Alice gets a notification linking back here. The task chip links straight to the task.

The Four Entity Types

Mentions come in four flavors. Each gets its own color so you can scan a paragraph and immediately see what's being referenced.

@user: People
Mention a teammate. Renders as a blue chip with their display name. Only mention type that fires a notification.
Example
Can @Alice Cooper take a look?
@project: Projects
Cross-reference another project. Renders as a purple chip linked to the project page. Render-only — no notifications.
Example
Shared dependency with #Apollo.
@workunit: Workunits
Link to another workunit. The chip shows its parent project as muted context so the reference stays unambiguous.
Example
@task: Tasks
Link to a specific task. The chip shows the parent workunit as muted context — "Refactor cache layer" alone is ambiguous, "#Ship the rocket: Refactor cache layer" isn't.
Why the muted prefix? Task and workunit names are often ambiguous out of context — multiple workunits can have a task called "Fix bug," and multiple projects can have a workunit called "Ship the rocket." The muted parent name gives readers the "where" without forcing a click.

Using the Picker

Anywhere you can write rich text in Workunit, typing the @ key opens the mention picker. Keep typing to filter — the picker searches across people, projects, workunits, and tasks in your organization.

What the picker looks like
@ali
@ Alice Cooper [email protected]
@ Alistair Wu [email protected]
Keyboard
  • / navigate the list
  • Enter or Tab select
  • Esc closes the picker
Mouse
  • Hover to highlight a row
  • Click to insert
  • Click outside to dismiss

Filtering by Type

Sometimes you know what kind of thing you're looking for. Type the entity prefix followed by a colon to restrict the picker to one type — fast scoping without scrolling through unrelated results.

TypePrefix to typePicker shows
People@user:Org members only
Projects@project:Active projects in the org
Workunits@workunit:Active workunits across all projects
Tasks@task:Active tasks with parent workunit as sublabel
Bare @ with no prefix mixes all four types in one list, ordered by relevance. Use a prefix when you've got a lot of matches and want to narrow down fast.

Paste a URL, Get a Mention

Got a workunit URL from a Slack message or a browser tab? Just paste it. If the URL points at one of the four entity types in your org, it auto-converts to a canonical mention chip — same as if you'd used the picker.

1. You paste a URL
https://workunit.app/orgs/<org>/projects/<p>/workunits/<w>/tasks/<t>
2. It becomes a chip, instantly
Works for all four types
User profile, project, workunit, and task URLs are all recognized. Paste any of them and they'll convert.
Cross-org URLs pass through
A URL pointing at a different org won't match — the paste keeps the raw URL untouched, since the chip wouldn't resolve anyway.
Both UUID forms accepted
Hyphenated (abcd-...-1234) or dashless (abcd...1234) — both work, both get normalized.
Ctrl-Z reverts
If you didn't mean to convert, the standard browser undo restores the original paste.

Who Gets Notified

Only @user mentions fire notifications. Project, workunit, and task mentions are render-only — they make text scannable, but they don't ping anyone.

@user fires a notification
When you mention someone, they get an in-app notification, an email (if enabled in their prefs), and a push (if subscribed). The notification links back to wherever they were named.
You were mentioned
Alice mentioned you on a task: "Refactor cache layer"
@project, @workunit, @task are links
No fan-out, no notifications. These mentions exist to make text easy to scan and navigate — the chip is the link, that's the whole feature.
Smart deduplication
If you mention the same person twice on the same entity (e.g. you edit a description and add another @alice), they won't get a duplicate ping. The notification re-fires only if the previous one was read or it's been more than six hours.
Self-mentions drop silently
Mentioning yourself in your own description or comment doesn't trigger anything. Same for users outside your org — they just won't resolve.

Where Mentions Work

Mentions are available in every text surface where teams collaborate:

Workunits
Description, problem statement, success criteria
Tasks
Description, acceptance criteria, comments
Chat
Every message
Signals
Body and comments
Assets
Descriptions across all four types
Knowledge
Content body
Context atoms
Title and content
Calendar events
Description and comments

Best Practices

Make mentions earn their notifications — and use the other three types liberally to keep text scannable.

Mention a person when you need them

If you need someone's review, decision, or input, mention them. If you're just describing what they did, write their name as plain text — no need to ping them about their own work.

Link work liberally

Workunit, task, and project mentions are free — no notifications, just navigation. The more your writing cross-references concrete entities, the more useful the team's trail-of-thought becomes for anyone reading later.

Paste URLs without thinking

Copying a link from one browser tab to another comment? Just paste — the URL becomes a proper mention chip automatically. No need to manually retype @task: or hunt through the picker.

Trust the dedup

If you edit a description and need to keep an existing @alice in there, don't worry about double-pinging — Workunit checks whether Alice was already notified about this entity recently and skips the duplicate.

When NOT to mention

  • Recap mentions: "Alice did X and Bob did Y" — they don't need a notification about their own work. Write names as plain text in retrospectives.
  • Long thread cc's: If you'd cc the whole team on every reply in email, mentioning all of them in chat will do the same noisy thing. Mention only who actually needs to act.
  • Self-reminders: Mentioning yourself doesn't fire anything anyway — just write a task instead if you need a reminder for later.
