# flutter-app-runtime: PreInvocation handler (Antigravity).
|
|
#
|
|
# PreInvocation (per Antigravity hooks documentation):
|
|
# Fires before the model is called. There is no matcher -- the event key
|
|
# holds a flat list of handlers, and any matcher would be ignored.
|
|
# Input (stdin, camelCase JSON):
|
|
# invocationNum - integer; 0-indexed sequence number of this model
|
|
# invocation (the first invocation is 0)
|
|
# initialNumSteps - integer; number of steps currently in the trajectory
|
|
# plus common fields: conversationId, workspacePaths, transcriptPath,
|
|
# artifactDirectoryPath, modelName
|
|
# Output (stdout):
|
|
# injectSteps - optional array of steps injected into the conversation
|
|
# trajectory before the model is called. Each step carries
|
|
# one of: `toolCall` (a tool call to execute), `userMessage`
|
|
# (a message from the user), or `ephemeralMessage` (a
|
|
# transient system message -- what this hook uses).
|
|
#
|
|
# This is the injection point: if a .dart file was edited since the last model
|
|
# call, inject a one-shot reminder pointing the agent at the
|
|
# flutter-app-runtime skill.
