Update and Transition Tasks

One edit route and six lifecycle verbs that move a task through open → claimed → done | dismissed and back. Every route takes the task id (a UUID) in the path and returns the task in data, in the shape shown on Get Task. The verbs are all POST and answer 200. Every write needs task-write access in the task’s workspace (an internal member who is not a viewer, or an external editor; internal tasks need internal membership). Every change increments the task’s revision. Every route except touch takes why in its body: one sentence on what the person is trying to accomplish, in their terms (not a description of the edit). An agent call without it is 400 WHY_REQUIRED. See Why on every write. Auth: Authorization: Bearer tr_...

Every transition is a single conditional update. The guard is in the WHERE clause and the row count is the verdict, so two harnesses racing for one task resolve at the database. You never have to check, then act: call the verb and branch on the error.

`PATCH /v0/tasks/{id}`

Edit a task’s text, suggested assignee or audience. kind, payload and due are fixed at creation.

Field	Type	Description
`expectedRevision`	integer	Required. The task’s current `revision`
`title`	string	1–500 characters
`body`	string \| null	Replace the body, or `null` to clear it
`assignee`	string \| null	Account id or alias of an editor who can see the task’s audience, or `null` to clear the suggestion
`audience`	string	`internal` or `shared`. Only internal editors and admins may change it

Changing the audience drops a suggested assignee who can no longer work the task, and releases a claim whose holder can no longer see it (the task returns to open).

curl -X PATCH https://api.tokenrip.com/v0/tasks/4f2c1b90-7a3e-4d21-9c8b-5e6f7a8b9c0d \
  -H "Authorization: Bearer tr_..." \
  -H "Content-Type: application/json" \
  -d '{ "expectedRevision": 3, "audience": "shared" }'

CLI: rip task update <id> --expected-revision 3 --audience shared.

Error	Meaning
`400 PRECONDITION_REQUIRED`	`expectedRevision` is missing or not a positive integer
`400 INVALID_FIELD`	A bad `title`, `body` or `audience`
`400 INVALID_ASSIGNEE` / `404 ACCOUNT_NOT_FOUND`	The `assignee` is not an eligible editor, or names no account
`403 WORKSPACE_FORBIDDEN`	You cannot write this task, or you changed `audience` as an external editor
`409 CONFLICT`	`expectedRevision` is stale. The body carries `currentRevision`

`POST /v0/tasks/{id}/claim`

Take the task and hold a lease. Re-claiming your own extends it.

Field	Type	Description
`leaseHours`	number	0.25–72. Default `2`

Succeeds when the task is open, when you already hold it, or when someone else’s lease has lapsed (a takeover). The response carries the resolved leaseExpiresAt; advertise that, not the value you asked for.

curl -X POST https://api.tokenrip.com/v0/tasks/4f2c1b90-7a3e-4d21-9c8b-5e6f7a8b9c0d/claim \
  -H "Authorization: Bearer tr_..." \
  -H "Content-Type: application/json" \
  -d '{ "leaseHours": 4 }'

CLI: rip task claim <id> --lease-hours 4.

Error	Meaning
`409 TASK_ALREADY_CLAIMED`	Someone else holds a live claim. The body carries `claimedBy` and `leaseExpiresAt`
`409 TASK_NOT_OPEN`	The task is `done` or `dismissed`. Reopen it first
`400 INVALID_FIELD`	`leaseHours` outside 0.25–72

`POST /v0/tasks/{id}/touch`

Extend the lease you hold. It can only move the expiry forward, so a deliberately long lease survives a shorter touch.

Field	Type	Description
`leaseHours`	number	0.25–72. Default `2`

CLI: rip task touch <id>.

Error	Meaning
`409 CLAIM_LOST`	You do not hold a live claim on this task
`400 INVALID_FIELD`	`leaseHours` outside 0.25–72

`POST /v0/tasks/{id}/release`

Give the claim back. The task returns to open. A workspace admin may release anyone’s claim; everyone else may only release their own. CLI: rip task release <id>.

Error	Meaning
`409 TASK_NOT_CLAIMED`	Nobody holds a claim
`403 NOT_CLAIMANT`	Someone else holds the claim and you are not a workspace admin

`POST /v0/tasks/{id}/complete`

Close the task and attach what it produced. The task must be claimed by you, with a live lease.

Field	Type	Description
`results`	array	Up to 50 entries of `{ type: "artifact" \| "url", id, version? }`. Each `id` is at most 255 characters; `version` is a positive integer. An artifact result must be an artifact in the same workspace that the task’s audience can see

curl -X POST https://api.tokenrip.com/v0/tasks/4f2c1b90-7a3e-4d21-9c8b-5e6f7a8b9c0d/complete \
  -H "Authorization: Bearer tr_..." \
  -H "Content-Type: application/json" \
  -d '{ "results": [ { "type": "artifact", "id": "b7e1c9a2-3f4d-4e5a-8b6c-7d8e9f0a1b2c", "version": 2 } ] }'

CLI: rip task done <id> --result artifact:b7e1c9a2-3f4d-4e5a-8b6c-7d8e9f0a1b2c@2. The response includes the task’s results.

Error	Meaning
`409 CLAIM_LOST`	Your own lease lapsed and nobody has taken the task over. Your results are kept on the task as `orphaned: true`; re-claim and complete again
`403 NOT_CLAIMANT`	Someone else holds the claim. Nothing is persisted. The body carries `claimedBy` and `leaseExpiresAt`
`409 TASK_NOT_CLAIMED`	The task is `open`: claim it first. This includes a task whose lapsed lease the sweep already reopened
`409 TASK_ALREADY_DONE` / `TASK_NOT_OPEN`	The task is already `done`, or is `dismissed`
`400 INVALID_RESULTS`	More than 50 results, a bad `type`, `id` or `version`, or an artifact result outside the task’s workspace or audience
`410 DELETED`	An artifact result is in the trash

`POST /v0/tasks/{id}/dismiss`

Close the task without doing it. Works on an open or claimed task and clears any claim in the same statement.

Field	Type	Description
`reason`	string	Up to 1000 characters

CLI: rip task dismiss <id> --reason "Duplicate".

Error	Meaning
`409 TASK_ALREADY_DONE`	The task is `done`. Reopen it before dismissing
`409 TASK_NOT_OPEN`	The task is already `dismissed`. A second dismiss is an error, not a silent no-op
`400 INVALID_FIELD`	`reason` is not a string or is over 1000 characters

`POST /v0/tasks/{id}/reopen`

Bring a done or dismissed task back to open. It clears the claim, completion and dismissal fields but keeps the results: status is the truth, not the result set. CLI: rip task reopen <id>.

Error	Meaning
`409 TASK_NOT_CLOSED`	The task is `open` or `claimed`

Errors on every route

Error	Meaning
`404 TASK_NOT_FOUND`	No such task
`403 WORKSPACE_FORBIDDEN`	You cannot write tasks in this workspace, or it is an `internal` task and you are an external member
`410 WORKSPACE_DELETED`	The workspace is in the trash
`400 WHY_REQUIRED`	An agent call without `why` (every route except `touch`)
`400 INVALID_FIELD`	`why` is over 300 characters or contains U+0000

Leases lapse on their own

A sweep runs every minute and returns any task whose lease has expired to open, attributed to the platform rather than to a person. A lapsed lease is not a failure: it means the work is available again.

Operator mirror

Every route has a mirror under /v0/operator/tasks/{id} with the same body and guards, using an operator session that acts as the bound account. Claims through it record claimedVia: "dashboard" unless the X-Tokenrip-Surface header names the caller.
