Action — setup-claude-code

Installs the Claude Code CLI (claude) on a Linux runner, pinned to one version and checked against the SHA-256 recorded in this repository for each architecture. Used by pr-description.yml.

Usage

steps:
  - uses: KevinDeBenedetti/github-workflows/.github/actions/setup-claude-code@main

  - run: claude --version

Inputs

None.

Steps

1. Pick the release binary for the runner: linux-x64 or linux-arm64 (glibc only)
2. Download it from downloads.claude.ai and check it against the pinned SHA-256
3. Add its directory to PATH

Notes

• No version input: a version chosen by the caller could not be checked against a pinned checksum. The version follows the release of this repository you pin.
• The pinned SHA-256 values are the ones listed in the release's signed manifest.json. Renovate bumps the version (npm datasource, @anthropic-ai/claude-code); the job then fails closed until scripts/update-tool-checksums.py refreshes the checksums.
• The action sets no credential. The CLI authenticates with CLAUDE_CODE_OAUTH_TOKEN (subscription) or ANTHROPIC_API_KEY in the step that runs it.
