Schema Documentation — Schema Skill

This skill provides the data schema context for Schema Documentation. Consult it whenever you need to understand the data model, write type-safe code against it, or respect its constraints.

Schema Overview

This schema contains 9 models, 3 views, 2 types, 3 enums, 7 procedures.

Entities:

Activity (Model) — Records significant events for audit and activity feed purposes.
Comment (Model) — A comment on a task. Comments do not have descriptions intentionally
Organization (Model) — An organization is the top-level tenant in the system.
Project (Model) — A project organizes tasks under a team within an organization.
ProjectTaskSummary (View) — Aggregated task metrics per project for analytics dashboards.
Tag (Model) — A label that can be attached to tasks and projects for categorization.
Task (Model) — A unit of work within a project.
Team (Model) — A team groups users within an organization for project collaboration.
TeamMember (Model) — Represents a user's membership in a team with a specific role.
User (Model) — A registered user in the platform.
UserLeaderboard (View) — Leaderboard view ranking users by completed task count.
UserProfile (View) — Flattened user profile for reporting dashboards.

Conventions

Follow these patterns when working with this schema:

IDs: Most models use @default(cuid()) for IDs. Exceptions: 1 use uuid().
Mixins (shared field sets applied via with):
- Timestamps (createdAt, updatedAt) — used by Organization, User, Team, TeamMember, Project, Task, Comment, Activity
Computed fields are read-only and derived at the database level. Never set them directly:
- Organization.memberCount — Total number of users across all teams.
- User.taskCount
- Project.taskCount — Total number of tasks in this project.
- Project.completionRate — Percentage of completed tasks (0.0–1.0).
- Project.hasOverdueTasks — Whether the project has any tasks past their due date.
- Task.commentCount — Number of comments on this task.
Relations: 9 of 9 models have relationships. When creating records, always provide required foreign key fields (e.g. organizationId, userId, teamId).

Constraints You Must Respect

Access Policies

ZenStack enforces these rules at the ORM level. Your code does not need to re-implement them, but you must be aware of them when reasoning about what operations will succeed or fail.

Some rules reference auth() — the currently authenticated user. Operations that require auth() will fail for unauthenticated requests.

Activity: allow('read', true) · deny('update,delete', true)

Comment: allow('read', true) · allow('create', true) · allow('update,delete', author == auth())

Organization: allow('read', true) · allow('update,delete', users?[role == 'OWNER'])

Project: allow('read', true) · allow('create,update', true) · deny('delete', archived)

Task: allow('read', true) · allow('create,update', true) · deny('delete', status == 'DONE')

Team: allow('read', true) · allow('create,update,delete', members?[role == 'ADMIN' || role == 'OWNER'])

TeamMember: allow('read', true)

User: allow('read', true) · allow('update', this == auth()) · deny('delete', role == 'OWNER')

Validation

These constraints are enforced at the schema level. When generating test data, seed scripts, or form inputs, produce values that satisfy them.

Organization: name: @length(2, 100), slug: @length(3, 40), email: @email
Project: name: @length(1, 100)
Tag: name: @length(1, 50)
Task: title: @length(1, 200), title: @trim, slug: @regex('^[a-z0-9-]+$'), estimatedHours: @gt(0), estimatedHours: @lte(1000)
Team: name: @length(1, 80)
User: email: @email, name: @length(1, 120), avatarUrl: @url

How To Use This Schema

Writing queries or mutations

Find the model in the Entity Reference below
Check its fields for types, optionality, and defaults
Check access policies — will the operation be allowed for the current user?
Check validation — will the input values pass schema-level validation?
For full field details, follow the entity documentation link

Calling procedures

This schema defines server-side procedures. Use them instead of writing raw queries when available:

archiveProject(projectId: String) → Project (mutation) — Archive a project and all its tasks. — archiveProject (Procedure)
bulkUpdateTaskStatus(taskIds: String[], status: TaskStatus) → Void (mutation) — Bulk-update the status of multiple tasks at once. — bulkUpdateTaskStatus (Procedure)
createAndAssignTask(title: String, projectId: String, assigneeId: String?, priority: Priority?) → Task (mutation) — Create a new task and assign it to a user in one step. — createAndAssignTask (Procedure)
getProjectStats(projectId: String) → ProjectStats (query) — Get aggregated statistics for a project. — getProjectStats (Procedure)
getUser(id: String) → User (query) — Retrieve a user by their unique identifier. — getUser (Procedure)
listOrgUsers(organizationId: String) → User[] (query) — List all users belonging to a given organization. — listOrgUsers (Procedure)
signUp(email: String, name: String, role: Role?) → User (mutation) — Register a new user in the platform. Creates the user record and sends a welcome email. — signUp (Procedure)

Generating test data

When creating seed data or test fixtures:

Respect @unique constraints — duplicate values will cause insert failures
Satisfy validation rules (see Constraints above)
Provide all required foreign keys for relations
Fields with @default(...) can be omitted — the database generates them
Fields with @computed cannot be set — they are derived

Understanding relationships

See the relationships page for a full ER diagram and cross-reference table.
