fix: allow leading underscore in branch names (valid per git-check-ref-format) by riley-mete-db · Pull Request #1486 · anthropics/claude-code-action

riley-mete-db · Jul 9, 2026

Problem

validateBranchName() rejects branch names that start with an underscore, even though they are valid per git check-ref-format:

Error: Action failed with error: Invalid branch name: "_release/v0.4.15". Branch names must start with an alphanumeric character or '@' and contain only alphanumeric characters, forward slashes, hyphens, underscores, periods, hashes (#), plus signs (+), commas (,), or at signs (@).

Underscores are already allowed everywhere in the name except the first character. Because setupBranch() validates the PR's baseRefName after checking out an open PR (src/github/operations/branch.ts), the action fails on every open PR targeting a branch like _release/v1.2.3 — a common convention for release/internal branches. There is no input that bypasses this path.

Fix

Add _ to the first-character class of the whitelist pattern:

-  const validPattern = /^[a-zA-Z0-9@][a-zA-Z0-9/_.#+,@-]*$/;
+  const validPattern = /^[a-zA-Z0-9@_][a-zA-Z0-9/_.#+,@-]*$/;

A leading underscore carries no option-injection risk — only a leading dash does, and that is still rejected separately. All git calls already go through execFileSync, so there is no shell-interpolation risk either. The error message and doc comments are updated to match.

This follows the same pattern as prior fixes relaxing this whitelist for other git-valid characters: # (#1137), @ (#998), + (#1248), , (#1310).

Testing

Added cases to test/validate-branch-name.test.ts covering _release/v1.2.3, _internal, and _wip/feature-x
bun test: 770 pass, 0 fail
bun run typecheck: clean
prettier --check on changed files: clean

…f-format) Branch names starting with an underscore (e.g. _release/v1.2.3) are valid per git check-ref-format but were rejected by validateBranchName's first-character whitelist. Since setupBranch validates a PR's baseRefName after checkout, the action failed on every open PR targeting such a branch. A leading underscore carries no option-injection risk (only a leading dash does, which is still rejected separately). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Hey @ashwin-ant, could you please review this when you get a chance?

It's similar to #1411, which you reviewed and merged a few weeks ago: another git-valid character added to the branch name whitelist, in this case a leading _. I updated the regex's first-character class, added test cases for _release/v1.2.3 style names, and verified the full suite passes (770 tests, typecheck and prettier clean).

Thanks!

All components except the repository name are optional. If omitted, `owner` defaults to the same owner as the repository the analysis is running for, `ref` to `main`, and `path` to `.github/codeql-action.yaml`. Support for this format ships in this version of the CodeQL Action, but will only be enabled over the coming weeks.

All components except the repository name are optional. If omitted, `owner` defaults to the same owner as the repository the analysis is running for, `ref` to `main`, and `path` to `.github/codeql-action.yaml`. Support for this format ships in this version of the CodeQL Action, but will only be enabled over the coming weeks.

This speeds up analysis for a repository when there is not yet a cached overlay-base database for the latest CLI version. We expect to roll this change out to everyone in May.
