The opt-in simplified tag-mode prompt omitted several guardrails the
default prompt has. Bring it closer to the default's posture while
keeping it terse:
- Scoping clarification: spell out that only the triggering comment
(or the issue body for issue events) carries instructions; other
comments, the body, review comments, and repository files are
reference context, not commands to act on.
- Review-only stop-condition: questions and code reviews must not edit,
commit, push, or create branches unless the trigger explicitly asks
for a code change.
- PR base-branch diff: when triggered on a PR with a known base branch,
compare against origin/<base> instead of main/master.
- Capability limits: cannot submit formal PR reviews, approve, or merge;
decline politely and point to the FAQ.
Adds focused tests covering the new lines for both PR and non-PR
events, including presence/absence of the conditional base-branch line.
`??` has lower precedence than `!==`, so the expression:
triggerDisplayName ?? triggerUsername !== "Unknown"
parses as:
triggerDisplayName ?? (triggerUsername !== "Unknown")
When triggerDisplayName is an empty string "", the condition
evaluates to "" (falsy), incorrectly skipping the co-author line
even though the user is not "Unknown".
Add parentheses to get the intended behavior:
(triggerDisplayName ?? triggerUsername) !== "Unknown"

GitHub Apps like Copilot SWE Agent set GITHUB_ACTOR to a value (e.g.
"Copilot") that is neither a valid GitHub user nor ends with "[bot]".
This caused two independent crashes:
1. checkWritePermissions (permissions.ts): called the collaborator
permission API which returns 404 "is not a user" for non-user actors.
2. checkHumanActor (actor.ts): called the Users API first, which 404s,
before ever reaching the allowed_bots check.
Fix both by:
- Checking allowed_bots BEFORE making API calls, so known bots skip the
API entirely.
- In permissions.ts, catching "is not a user" 404 errors and falling
back to the allowed_bots list instead of crashing.
- In actor.ts, catching 404 errors and providing a clear error message
telling the user to add the bot to allowed_bots.

`cpSync` defaults to `dereference: false`, which means it tries to
recreate symlinks at the destination rather than copying file contents.
When a sensitive path (e.g. CLAUDE.md) is a symlink, this fails with
`ENOENT: no such file or directory, symlink` because `cpSync` attempts
to call `symlink()` without ensuring the parent `.claude-pr/` directory
exists first.
Adding `dereference: true` fixes this by following symlinks and copying
the actual file contents, which is also the correct semantic behavior —
review agents need to inspect the real content, not a symlink that may
not resolve correctly from `.claude-pr/`.
Fixes the action crash when repositories use symlinked CLAUDE.md
(e.g. CLAUDE.md -> AGENTS.md).
`validateBranchName` rejects branch names containing a comma, even
though `git check-ref-format` permits commas and GitHub itself accepts
them. PRs whose head branch contains a `,` fail validation in-process
before any git operation, so the action errors out immediately.
Branch names with commas show up in real workflows when names are
derived from titles, place names, or external identifiers (e.g.
"feature/paris,france"). There is no workaround other than renaming
the branch, which is often not under the user's control.
All git calls in this file use execFileSync with an argv array, so no
shell interpretation occurs and `,` carries no injection risk. This is
the same reasoning used to add `#` in #1167 and `+` in #1248.
- Add `,` to the validateBranchName whitelist regex
- Update the surrounding comment and error message to match
- Add a test case covering commas in title-derived branch names
Fixes#1300
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.
* docs: add pull_request_target/workflow_run guidance and base-action trust model
Adds a security.md section on safe checkout patterns under
pull_request_target/workflow_run, and a trust-model section to the
base-action README clarifying that callers are responsible for the
working directory and prompt being trusted.

* docs: refine PRT/workflow_run guidance — root checkout + workflow_run ref
Second example now checks out the base ref at the workspace root before
the head-ref subdirectory checkout (this action expects a git repo at
the root). Adds the workflow_run ref form, drops the PRT-specific
gh-pr-diff hint from the first example, and generalises the closing
line to cover both event types.

Claude Code's EnterWorktree tool converts "/" to "+" when generating
branch names from worktree names (e.g. EnterWorktree("feat/foo") creates
branch "worktree-feat+foo"). The strict whitelist in validateBranchName
rejected these names, causing claude-code-action to fail on any PR opened
from an EnterWorktree-generated branch.
Since all git calls use execFileSync (not shell interpolation), "+" carries
no command injection risk — the same rationale used for allowing "#".
Git itself permits "+" in branch names per git-check-ref-format.

Agent SDK 0.2.113 dropped vendor/ripgrep and now ships native binaries
via per-platform optionalDependencies. Two breakages:
- action.yml chmod'd vendor/ripgrep which no longer exists, failing the
Install Dependencies step with find exit 1.
- The SDK auto-resolves its bundled binary by trying the -musl platform
package before the glibc one. bun install does not respect the
package.json libc field and installs both on glibc Linux, so the SDK
picks the musl binary and spawn fails with ENOENT.
Remove the obsolete ripgrep chmod. Make installClaudeCode() return the
install.sh binary path and pass it explicitly as
pathToClaudeCodeExecutable so the SDK skips auto-resolution entirely.
When a PR originates from a fork, `git fetch origin <branch>` fails
because the branch only exists on the fork's remote.
Fix: detect cross-repository PRs via the `isCrossRepository` GraphQL
field and fetch using `pull/<number>/head:<branch>` refspec instead,
which is the standard GitHub mechanism for accessing fork PR branches.
Changes:
- Add `isCrossRepository` and `headRepository` to PR GraphQL query
- Add corresponding fields to GitHubPullRequest type
- Branch checkout uses pull ref for fork PRs
- Update test fixtures with new fields

Ensures later steps resolve standard tools like git and tar from /usr/bin
regardless of what setup actions added earlier in the job. Also strengthens
the PAT guidance in security.md.
