User Management

Looks up a user by any platform identity. Use this BEFORE creating a new user.

resolve-user with:
  slackUserId: "U12345"       # Slack member ID
  # OR
  githubUsername: "octocat"    # GitHub username
  # OR
  gitlabUsername: "octocat"    # GitLab username
  # OR
  linearUserId: "uuid"        # Linear user UUID
  # OR
  email: "[email protected]"   # Primary email or alias
  # OR
  name: "Jane Doe"            # Fuzzy name search (least specific)

Priority order: platform IDs > email > name. Platform IDs are exact matches; email checks aliases (case-insensitive); name is substring match.

manage-user — CRUD operations

# Create a new user
manage-user with:
  action: "create"
  name: "Jane Doe"                          # Required
  email: "[email protected]"                 # Optional
  role: "engineering lead"                  # Optional, free-form
  slackUserId: "U12345"                     # Optional
  githubUsername: "janedoe"                 # Optional
  gitlabUsername: "janedoe"                 # Optional
  linearUserId: "uuid-from-linear"          # Optional
  emailAliases: ["[email protected]"]    # Optional
  timezone: "America/New_York"              # Optional
  notes: "Prefers async communication"      # Optional

# List all users
manage-user with:
  action: "list"

# Get a specific user
manage-user with:
  action: "get"
  userId: "<uuid>"

# Update a user (only send fields to change)
manage-user with:
  action: "update"
  userId: "<uuid>"
  githubUsername: "new-username"

# Delete a user
manage-user with:
  action: "delete"
  userId: "<uuid>"

Workflow: New Slack User

1. Receive a message from an unknown Slack user (e.g., slackUserId: "U_NEW123")
2. Call resolve-user with slackUserId: "U_NEW123" — returns null
3. Get the user's Slack profile (name, email) via slack-read or from the message metadata
4. Call resolve-user with email: "<their-email>" — check if they exist under a different platform
5. If found: call manage-user with action: "update" to add their slackUserId
6. If not found: call manage-user with action: "create" including name, email, and slackUserId

Workflow: New GitHub User

1. Receive a webhook from an unknown GitHub user (e.g., githubUsername: "octocat")
2. Call resolve-user with githubUsername: "octocat" — returns null
3. Call manage-user with action: "create" including at minimum name and githubUsername
4. If you know their email (from the webhook payload), include it

Workflow: Linking Identities

When you discover a known user is also active on another platform:

1. Call resolve-user to find them by their known identity
2. Call manage-user with action: "update" to add the new platform identity

Example: You know "Jane" by Slack ID, and discover her GitHub username:

resolve-user slackUserId: "U_JANE"  → returns user with id "abc-123"
manage-user action: "update" userId: "abc-123" githubUsername: "janedoe"

Important Notes

• manage-user is lead-only — workers cannot use it for any action (the lead check happens before action dispatch). Workers must use resolve-user for lookups.
• slackUserId, githubUsername, gitlabUsername, and linearUserId have unique constraints — duplicates will error.
• Deleting a user clears requestedByUserId on all their associated tasks (sets to null).
• Email aliases are case-insensitive for resolution.
• The preferredChannel field defaults to "slack" and can be "slack", "email", "github", or "gitlab".
