Measured

2026-10-31, Antigravity CLI (agy) 1.4.12 (one process) and Cursor CLI 2026.10.22-27dcf5f (no process), on Windows 11 Pro 10.0.26300 (x64). The probe kit (probes/run.ps1) listed the state folders with names, sizes and times. It read no content. Measured on: real machine.

What was measured

  1. agy keeps its state in ~\.gemini\antigravity-cli\, with the same names as on Linux and macOS: conversations\<uuid>.db, presence\<uuid>.lock, brain\<uuid>\, log\, conversation_summaries.db, history.jsonl and settings.json. No agy folder exists below %APPDATA% or %LOCALAPPDATA% other than the install folder %LOCALAPPDATA%\agy\bin\.
  2. presence\ held 10 lock files, while one agy process ran. The lock files stay after a process stops. Fact 044 shows that a live process holds a flock lock on its file on Linux.
  3. log\ held one file for each start, named cli-<yyyyMMdd>_<HHmmss>.log. crashes\ held crash_<pid>_<uuid>.log, with the pid of the process that ran.
  4. The last records of the newest agy transcript had the types PLANNER_RESPONSE and GENERIC.
  5. Cursor CLI keeps its state in ~\.cursor\ (chats\<hex>\<uuid>\, projects\, ai-tracking\, cli-config.json), and its login in %APPDATA%\cursor\auth.json. The commands are agent.cmd and cursor-agent.cmd in %LOCALAPPDATA%\cursor-agent\.
  6. On Windows, the name of a Cursor project folder is the project path with the drive letter and one dash: C-Users-<name>-<folder> or D-<folder>. Claude Code uses two dashes after the drive letter: D--<folder>.
  7. ~\.cursor\ held four files statsig-cache.json.<pid>.<uuid>.tmp, left from earlier processes.
  8. A closed Cursor chat folder held meta.json, prompt_history.json and store.db, with no -wal and no -shm file. The newest transcript ended with a turn_ended record.

Mechanism

A presence lock file of agy does not prove a live process on Windows, as on Linux. A reader must test the lock or find the process.

A project folder name holds the project path, and on Windows also the drive letter and the account name. A tool that shows or sends these names must scrub them. The scrub of this repository missed both Windows forms on this run; the fix adds them.

Incident

The kit sent project folder names and the account name in the output of this run, because the scrub did not know the Windows key forms.

Screens

None.
