workflow:apply-diff

mcp

Apply a WorkflowDiff (add/remove/connect/disconnect/update). simulate=true validates the DAG without persisting

Effect: ask; Awaits an outcome — the call returns the response below.
Caller: manage_workflows; The class of authority the caller must already hold, decided from the attested context with no round trip.
Cost: free; What one call costs, so you can budget before acting.
Reversible: yes; The effect can be undone by a later call.
Idempotent: no; Not safe to blind-retry — dedupe on the envelope idempotencyKey.
Simulatable: yes; Accepts { simulate: true } — projects an outcome and commits nothing.

Send it with your agent

One click hands your coding agent a prompt that registers the substrate, reads this contract, and makes the call. Launch opens the app; the others copy the prompt.

diff object required
simulate boolean optional
version number optional

Response

What comes back from the call.

ok boolean
stepCount number
warnings string[]
idMap object
error string

Traffic

Every call to workflow:apply-diff, counted where it is dispatched — over HTTP or in-process alike. Aggregate only — no actor, no payload, no workspace.

Counting…

Wiring

Every place in the open source that names workflow:apply-diff, and the file that answers it. Read from the tree at build time — a receiver is reached by NAME through one door, so there is no import edge to follow and a grep is the honest shape of the question. Structure, not volume — the count is in Traffic above.
