Write settings.json without granting git star main

Claude Code settings that grant Bash(git * main) now greet you with a startup warning. The file you actually want is smaller, and git push still knocks.

The 2.1.246 changelog named that rule on purpose. A star before the subcommand is a blank in a form, not a lock on main. Claude Code's permissions docs already tell you to put the star after git log or git commit. This walkthrough writes that file and leaves git push on ask.

The sibling post covers why a wildcard before the subcommand matches options. This one is the paste. You should leave with a settings.local.json that starts quiet.

What has to exist first

Write the local file, with the user and project tabs waiting on the sides.

Pin Claude Code 2.1.246 or later. That is the release that warns on a wildcard before the subcommand. Run claude --version before you edit anything. If you are still on 2.1.245, the file below still helps, you just will not see the checkpoint.

Three JSON files can carry permission rules. User settings live in ~/.claude/settings.json and follow you into every repo. Shared project settings live in .claude/settings.json and wait on workspace trust for allow rules. Local settings live in .claude/settings.local.json at the git root.

This walkthrough writes the local file. Claude Code already saves "Yes, and don't ask again" there. Untracked local allow rules skip the trust dialog. A committed allow list does not.

• Claude Code 2.1.246+, confirmed with claude --version
• A git repository, so the local file sits at the repo root
• An editor that will not insert a trailing comma (settings files are strict JSON)

A // comment or a trailing comma is a syntax error. Claude Code then treats the file as a Settings Error and continues without it.

Write the local file

Five edits. Each one has a thing you can see. Skip the temptation to merge them into Bash(git *). That is the rule the warning is about.

1. Open the file Claude writes

From the repository root, open .claude/settings.local.json. If the file is missing, create it. Claude Code will also create it the first time you approve a Bash command for good.

Confirm git is ignoring it. On this machine the global excludes file already has **/.claude/settings.local.json. If you created the file by hand and Claude Code has never written to it, add that pattern to .gitignore yourself. Claude Code's settings page says the same thing.

git check-ignore -v .claude/settings.local.json

Checkpoint. The command prints a matching ignore rule. If it prints nothing, the file can leak into a commit, and then its allow list waits on trust like a shared project file.

2. Delete git star main

Search the allow array for git * main and for git *. Both are the shape 2.1.246 warns about. The changelog uses Bash(git * main) as the example because that rule also matches options inserted before the subcommand.

The official matches table is not subtle. Bash(git * main) matches git merge main, git push origin main, and git -c core.fsmonitor=<script> diff main. It does not match bare git log. So the rule you thought locked the branch also unlocked -c, which git(1) documents as passing a configuration parameter that overrides config files.

{
  "permissions": {
    "allow": [
      "Bash(git * main)"
    ]
  }
}

Delete that line. Checkpoint. No allow entry still contains git, a space, a star, then main. If the dialog wrote Bash(git:*), that is the same family. Cut it too.

3. Allow after the subcommand

Write the commands you actually want to run without asking. Put the star after the subcommand. The permissions page's own example already does this for commits.

{
  "permissions": {
    "allow": [
      "Bash(git status *)",
      "Bash(git diff *)",
      "Bash(git log *)",
      "Bash(git add *)",
      "Bash(git commit *)"
    ],
    "ask": [
      "Bash(git push *)"
    ]
  }
}

That is the whole trick. Bash(git log *) allows git log and git log --oneline. It does not allow git push origin main. Bash(git commit *) allows git commit -m "msg". It does not allow git -c core.fsmonitor=... diff main.

The permissions docs already run read-only forms of git without a prompt in every mode, along with ls and diff. An unquoted glob on git still prompts, because git has write-capable flags. A redirect adds a write check on the target. The allow line is the standing yes for the forms you actually run.

Checkpoint. allow contains Bash(git commit *) and Bash(git log *). It does not contain Bash(git *).

4. Put git push on ask

The permissions page's sample JSON denies git push. That refuses the call. You want a knock. The settings reference is the paste that matches the title, ask with Bash(git push *).

Ask beats allow. Rules run deny, then ask, then allow. A matching ask prompts even when a broader allow also matches. So if a teammate later adds Bash(git *) in their user file, your local ask still stops the push for a click. Deny would swallow the click too. Use deny for .env reads, not for a push you sometimes mean to run.

A deny on git push is not a lock on git -c ... diff main. That call is not a push. If the leftover allow is still Bash(git * main), the -c form walks around the deny wall. Delete the star-before-subcommand rule. Do not paper over it.

Checkpoint. ask contains Bash(git push *). deny does not list git push.

5. Keep a space before the star

The space is load-bearing. Bash(ls *) matches ls -la and bare ls. It does not match lsof. Bash(ls*) matches both. Glue the star to git and you just granted gitignore adjacent junk plus every git subcommand.

The :* suffix is the other spelling of a trailing wildcard. Bash(git commit:*) matches the same family as Bash(git commit *). The permission dialog writes the space-star form. Use that. Colon-star is only recognized at the end of a pattern. Bash(git:* push) treats the colon as a literal character and matches nothing useful.

Checkpoint. Every trailing wildcard in the file is a space then a star, or a :* at the very end. No git*.

When the file skips itself

One bad $() rule used to blank the rest of the stack.

This is the section that actually costs you. A working allow list is boring. Invalid JSON still drops the whole local file. A malformed :* rule used to do the same, and on current builds it at least kills that one allow.

Claude Code used to skip the whole file when one permission pattern failed validation. GitHub issue 19929 quotes the line, "Files with errors are skipped entirely, not just the invalid settings." Issue 15056 is the 70-plus-rule version of the same punch, plus a saved git commit whose pattern was the entire heredoc body inside $().

The current settings page splits the failure. Invalid JSON is a Settings Error, and Claude Code continues without the broken file. A malformed permission rule is a Settings Warning, and Claude Code skips those values and keeps the rest. Either way, the bad rule is dead. A $() commit allow is not a reusable prefix.

The tripwire is a :* that is not at the end of the pattern. Bash parameter expansion loves that shape. $os%%:* is how you strip a suffix in a script. GitHub issue 19929 saved those inner lines as their own allow rules, including then and fi. The next launch then printed The :* pattern must be at the end.

"Bash(git commit -m \"$(cat <<'EOF'\nfeat: wire the thing\nEOF\n)\")"

If that string lands in allow, look at it. The :* inside the body is not a trailing wildcard. It is a colon sitting in a commit message, or in $(), or in ${var%%:*}. Delete the entry. Write Bash(git commit *) instead. Never let Yes-don't-ask-again save a heredoc.

Two other breaks that look like "the allow list is ignored."

• Glued star. Bash(git*) is the ls* bug with a sharper edge. Put the space back.
• git -C prefix. Claude often runs git -C some/dir status. That is not git status. A tight Bash(git status *) misses it, which is how people widen the rule to git *. Add a separate allow, or keep prompting. Do not replace the subcommand with a star. GitHub issue 36900 is this exact complaint.

You'll hit the -C miss the first week you let Claude wander a monorepo. That is not a reason to grant git * main. It is a reason to add one more specific line, or to live with one extra prompt.

What working looks like

Commit and log stay open while push still knocks, warning sign in the bin.

Restart Claude Code in the repo. The startup line should not warn about a wildcard before the subcommand. If it still names Bash(git * main), the rule is still loaded from some other file. Check user settings and a committed .claude/settings.json. Lists merge. Deleting it in local does not delete it in ~/.claude/settings.json.

Ask Claude to git log -5. It should run. Ask Claude to git commit a throwaway. It should run. Ask Claude to git push. You should get a prompt. That prompt is the product.

If push runs with no prompt, an allow is still matching it. Hunt Bash(git *), Bash(git:*), Bash(git * main), and a leftover Bash(git push *) sitting in allow instead of ask. Ask cannot lose to a more specific allow. It can lose to a missing ask plus a broad allow.

This repo's own local file, read for this post, had no git allow rules at all. The live :* in it was a python one-liner, trailing form, which is legal. Empty git allows plus a legal trailing :* is a quieter starting point than a star before main. Copy the JSON in step 3, not the emptiness.

The working file is five allow lines, one ask line, and no star sitting where git options sit. That is the whole job.
