Pin GitHub Actions to commit SHAs

GitHub @-mention autocomplete inserts @Claude (capitalized) when users
pick the bot from the dropdown, but the trigger regex had no 'i' flag,
so the action would log 'No trigger was met for @claude' and exit. The
workflow's outer 'if: contains(...)' gate is case-insensitive, so the
job runs and looks like it silently ignored the user.

The regex was case-sensitive since the initial commit with no test
asserting either behavior; the existing tests focus on word-boundary
precision (email@claude.com etc.), not case.

 For simply tagging @claude in issues and PRs out of the box, [check out the Claude Code action and GitHub app](https://github.com/anthropics/claude-code-action).
 
+## Trust model
+
+This action is a thin wrapper that installs and runs Claude Code with the inputs you provide. It does **not** enforce any trust boundaries on its own. Running this action in a directory is equivalent to running Claude Code in that directory — Claude reads project-level configuration (`.claude/`, `CLAUDE.md`, `.mcp.json`, etc.) from the working directory, and the action's own setup steps run from there as well.
+
+**The caller is responsible for ensuring the working directory and prompt are trusted.** If your workflow processes untrusted input (issues, fork pull requests, external comments), use [`anthropics/claude-code-action`](https://github.com/anthropics/claude-code-action) instead — it provides actor permission checks, restores project configuration from the base ref in PR contexts, and is the supported path for those scenarios.
+
+See [Claude Code's security documentation](https://docs.anthropic.com/en/docs/claude-code/security) and the [GitHub Actions guidance on `pull_request_target`](https://securitylab.github.com/research/github-actions-preventing-pwn-requests/) for background.

   - Is designed for automation workflows where user permissions are already restricted by the workflow's permission scope
   - When set, Claude does a best-effort scrub of Anthropic, cloud, and GitHub Actions secrets from subprocess environments. On Linux runners with bubblewrap available, subprocesses additionally run with PID-namespace isolation. This reduces but does not eliminate prompt injection risk — keep workflow permissions minimal and validate all outputs. Set `CLAUDE_CODE_SUBPROCESS_ENV_SCRUB: 0` in your workflow or job `env:` block to opt out.
   - Optionally set `CLAUDE_CODE_SCRIPT_CAPS` in your workflow `env:` block to limit how many times Claude can call specific scripts per run. Value is JSON: `{"script-name.sh": maxCalls}`. Example: `CLAUDE_CODE_SCRIPT_CAPS: '{"edit-issue-labels.sh":2}'` allows at most 2 calls to `edit-issue-labels.sh`. Useful for write-capable helper scripts.
-  - When using `allowed_non_write_users`, always pass `github_token: ${{ secrets.GITHUB_TOKEN }}`. The auto-generated workflow token is scoped to the job's declared permissions and expires when the job completes. **Do not use a personal access token** — a static token does not rotate between runs, and depending on the tools allowed via `claude_args`, the model could be used to recover part or all of it. We recommend restricting allowed tools (e.g. `claude_args: '--allowedTools "Bash(gh issue view:*)"'`) to the minimum required when using `allowed_non_write_users`.
+  - When using `allowed_non_write_users`, always pass `github_token: ${{ secrets.GITHUB_TOKEN }}`. The auto-generated workflow token is scoped to the job's declared permissions and expires when the job completes. **Do not use a personal access token** — a static token does not rotate between runs and could be partially or fully recovered over time via prompt injection. Restricting allowed tools via `claude_args` reduces the rate of recovery but may not eliminate the risk. We recommend restricting allowed tools (e.g. `claude_args: '--allowedTools "Bash(gh issue view:*)"'`) to the minimum required when using `allowed_non_write_users`.
 - **Token Permissions**: The GitHub app receives only a short-lived token scoped specifically to the repository it's operating in
 - **No Cross-Repository Access**: Each action invocation is limited to the repository where it was triggered
 - **Limited Scope**: The token cannot access other repositories or perform actions beyond the configured permissions
 
+## Using this action with `pull_request_target` or `workflow_run`
+
+`pull_request_target` and `workflow_run` execute with the **base repository's secrets**. If your workflow checks out the PR head (`ref: ${{ github.event.pull_request.head.sha }}` for `pull_request_target`, `ref: ${{ github.event.workflow_run.head_sha }}` for `workflow_run`) into `$GITHUB_WORKSPACE` before this action, the action and Claude run with that checkout as the working directory.
+
+**Do not check out an untrusted ref into the workspace root before this action.** Use one of these patterns instead:
+
+```yaml
+# Preferred — check out the base ref (default).
+- uses: actions/checkout@v6 # no `ref:` → base branch
+- uses: anthropics/claude-code-action@v1
+```
+
+```yaml
+# If you need the PR's files locally — check out the base ref at the workspace
+# root (this action expects a git repo there), then check out the head ref into
+# a subdirectory and pass it via --add-dir.
+- uses: actions/checkout@v6 # no `ref:` → base branch at workspace root
+- uses: actions/checkout@v6
+  with:
+    # For workflow_run use: ${{ github.event.workflow_run.head_sha }}
+    ref: ${{ github.event.pull_request.head.sha }}
+    path: pr-head
+- uses: anthropics/claude-code-action@v1
+  with:
+    claude_args: "--add-dir pr-head"
+```
+
+This is general guidance for these event types — see [GitHub's documentation](https://securitylab.github.com/research/github-actions-preventing-pwn-requests/).
+
+### `claude-code-action` vs `claude-code-base-action`
+
+`claude-code-base-action` is a lower-level building block that installs and runs Claude Code with the inputs you provide. It does not perform actor permission checks or restore project configuration from the base ref. If you need those behaviors, use this action (`claude-code-action`). See the [base-action README](../base-action/README.md#trust-model) for details.
