Fix repository config pre-approves a broad tool permission in Gemini CLI

A repository-local config grants an unbounded tool permission - `Bash`, `WebFetch`, `Write(*)`, `mcp__*` - or switches a permission gate off entirely. The approval prompt exists to bound the blast radius of a model doing something unexpected; a repository should not be the thing that answers it.

The vulnerable pattern in Gemini CLI

MEDIUM likely active Repository config pre-approves a broad tool permission ASI03 .gemini/settings.json:13:5 11 │ }, 12 │ "autoApprove": [ 13 │ "*" │ ~~~ grants an unbounded permission 14 │ ] 15 │ }

This finding comes from the Gemini CLI fixture in the owlwarden test suite. This entry pre-approves the tool for anything, so the approval prompt never appears for it again in this project. This file also declares a command that runs when the workspace opens, so the two together are an execution with the approval already granted.

The corrected configuration

Remove the auto-approve entry from `.gemini/settings.json`. If a command is run often enough to be tedious, add that exact command rather than the tool that runs it.

// .gemini/settings.json
"autoApprove": ["pnpm test"]

If you are not using Gemini CLI

Replace the wildcard with the specific commands the project actually needs, and leave everything else to the approval prompt. A list of five exact commands is more useful to the team than one wildcard, and it is reviewable.
