Fields

id: String

status: TaskStatus

title: String

description: Option<String>

Detailed description of the task’s context, goal, purpose, and desired outcome.

priority: TaskPriority

tags: Vec<String>

scope: Vec<String>

evidence: Vec<String>

plan: Vec<String>

notes: Vec<String>

request: Option<String>

Original human request that created the task (Task Builder / Scan).

agent: Option<TaskAgent>

Optional per-task agent override (runner/model/model_effort/phases/iterations/phase_overrides).

created_at: Option<String>

RFC3339 UTC timestamps as strings to keep the contract tool-agnostic.

updated_at: Option<String>

completed_at: Option<String>

started_at: Option<String>

RFC3339 UTC timestamp when work on this task actually started.

Invariants:

• Must be RFC3339 UTC (Z) if set.
• Should be set when transitioning into doing (see status policy).

estimated_minutes: Option<u32>

Estimated time to complete this task in minutes. Optional; used for planning and estimation accuracy tracking.

actual_minutes: Option<u32>

Actual time spent on this task in minutes. Optional; set manually or computed from started_at to completed_at.

scheduled_start: Option<String>

RFC3339 timestamp when the task should become runnable (optional scheduling).

depends_on: Vec<String>

Task IDs that this task depends on (must be Done or Rejected before this task can run).

blocks: Vec<String>

Task IDs that this task blocks (must be Done/Rejected before blocked tasks can run). Semantically different from depends_on: blocks is “I prevent X” vs depends_on “I need X”.

relates_to: Vec<String>

Task IDs that this task relates to (loose coupling, no execution constraint). Bidirectional awareness but no execution constraint.

duplicates: Option<String>

Task ID that this task duplicates (if any). Singular reference, not a list.

custom_fields: HashMap<String, String>

Custom user-defined fields (key-value pairs for extensibility). Values may be written as string/number/boolean; Ralph coerces them to strings when loading.

parent_id: Option<String>

Parent task ID if this is a subtask (child-to-parent reference).

Trait Implementations

impl Clone for Task

fn clone(&self) -> Task

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Task

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Task

fn default() -> Task

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Task

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for Task

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl Serialize for Task

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
