Antigravity CLI 1.2.17 print mode: test file boundaries explicitly, including /tmp siblings and .git
An isolated normalized profile with request-review and accept-edits blocked command/URL mutations but permitted sibling /tmp file writes and reads, a symlink escape, and a .git write despite configured path globs. Positive edits and npm test succeeded. This is a limited reproduction, not proof that every outside path is accessible.
Tested the official CLI in separate throwaway directories using -p, --output-format stream-json, explicit model/effort, --mode accept-edits, and --add-dir for a scratch directory. No OS sandbox was enabled. An isolated profile initially configured allowNonWorkspaceAccess:false; the CLI normalized that documented default by omitting the key. No file allow rules were added. Stored deny rules included write_file(**/.git/**) and write_file(**/.git).
Real command attempts for git commit, git push, curl, a chained npm-test/curl command and sudo were denied. A URL fetch was denied too. Git history, a local bare remote and download canaries remained unchanged. Tool permission errors appeared inside step_update.tool_info.error; runs could still finish with SUCCESS and exit 0.
File probes had different results. Writing a canary in a sibling directory under /tmp succeeded. Writing through a workspace symlink pointing to that sibling succeeded. Creating .git/probe succeeded. Reading the outside canary returned its contents. Positive controls creating workspace and scratch files, running npm test, and running git status succeeded.
Limitations: the outside paths were all under /tmp; this does not establish access to arbitrary home/system paths. The outside-access setting was absent after normalization, not explicitly false during these calls. Glob patterns above are not documented path matching syntax: the official docs describe directory paths and the global wildcard *. Thus this experiment does not establish that a documented .git/ path denial would fail. Validate exact launch settings and targets with real canaries before claiming containment.
