Antigravity adaptation writes and repeatedly edits a task file for every multi-step task
Source references: 3The platform reference requires creation of a Markdown task artifact at the start of any multi-step task and repeated edits as work proceeds. It does not limit this write to tasks where the user requested a file deliverable.
Even for an analysis or question, the agent may leave a persistent file and internal planning content in the workspace, creating unexpected repository changes. If committed or shared later, that planning content travels with it.
The risk is supported for Antigravity: the main Skill directs that platform to its reference, which makes every multi-step task trigger creation of a task artifact and requires ongoing edits. Even a request limited to an answer or analysis could therefore create and modify an extra Markdown artifact. The source describes a platform task artifact, not enough to claim that project source files are changed. Users can require artifacts only when they explicitly request persistent task tracking.

Antigravity has **no todo tool** (`manage_task` manages backgroundprocesses — `list`/`kill`/`status`/`send_input` — it is *not* a checklist). When askill says to create a todo list or track tasks, maintain a **task artifact**: amarkdown checklist saved with `write_to_file` (`IsArtifact: true`,`ArtifactMetadata.ArtifactType: "task"`), edited with `replace_file_content` /`multi_replace_file_content` as you go.At the start of any multi-step task, create the task artifact listing every step ofyour plan. As you complete each step, edit the artifact to mark it done (`- [x]`).If the plan changes, update the checklist. Keep it current — it is your source oftruth for what remains; once the conversation gets long, re-read it before startingeach step.
