act: undo.

A done action to the action, undone, and the inverse's own action

Figure 1POST /v1/act/undospecified

The caller sends UndoInput to /v1/act/undo. The platform returns a card whose body is UndoAnswer.

POST/v1/act/undo

Undo an action. The call needs the strategy rung under a token with the act grant, and it is served by the platform.

The route takes UndoInput and returns a card whose body is UndoAnswer.

Request body#

The request body is UndoInput.

field	type	required	note
`action`	`id`	yes
`reason`	`text`	yes

Response#

The route returns a card whose body is UndoAnswer. Every card ends with a foot that states the basis of each number, the scope of the call, and the time when the facts were true.

Headers#

header	required	meaning
`Scale-Scope`	yes	the scope the call runs in: tenant/, then /brand/, then /strategy/
`Scale-As-True-On`	no	the date the facts must have been true on; defaults to now
`Scale-As-Known-On`	no	the date the facts must have been known on; defaults to now
`Scale-Key`	no	for a change, the key made from the input; a repeat under the same key returns the unit held and writes nothing

A caller needs the strategy rung and a token with the act grant. The platform serves this route.

Example#

The example sends the smallest body that UndoInput allows. The build validates it against the schema of UndoInput.

Example

curl -X POST https://api.scaleintelligence.co/v1/act/undo \
  -H "Scale-Key: $SCALE_KEY" -H "Scale-Scope: tenant/<id>" \
  -H "content-type: application/json" \
  -d '{ "action": "…", "reason": "…" }'

import { client } from "@scale/sdk";
const answer = await client.act.undo({
    "action": "…",
    "reason": "…"
  });
// answer.body is a UndoAnswer. answer.foot holds the basis, the scope and the time.

import requests
answer = requests.post("https://api.scaleintelligence.co/v1/act/undo",
    headers={"Scale-Key": KEY, "Scale-Scope": "tenant/<id>"},
    json={
      "action": "…",
      "reason": "…"
    }).json()

let answer: Card = client.post("https://api.scaleintelligence.co/v1/act/undo")
    .header("Scale-Key", key).header("Scale-Scope", "tenant/<id>")
    .json(&UndoInput { /* the fields of the page */ }).send().await?.json().await?;

MCP tool#

The MCP tool si.act.undo takes the same input and returns the same card. The tool changes data and needs a grant. An MCP host that renders cards draws this card from ui://scale-intelligence/cards/UndoAnswer. The tool’s page describes it.

POST /v1/act/undo
Scale-Scope: …
Scale-As-True-On: …
Scale-As-Known-On: …
Scale-Key: …
content-type: application/json

{
  "action": "…",
  "reason": "…"
}

Without a key, this page shows the request only. The request body is UndoInput, and the route returns a card whose body is UndoAnswer.
