actions/checkout v4 and oven-sh/setup-bun v2.0.2 run on the deprecated
Node 20 action runtime and emit a deprecation warning on every run.
Bump to checkout v6.0.2 and setup-bun v2.2.0 (both Node 24).

* chore: bump actions/setup-node from v4.4.0 to v6.4.0 (Node.js 24)
setup-node v4 runs on the deprecated Node.js 20 action runtime, producing
a deprecation warning on every workflow run that uses base-action. v6 runs
on Node 24. This only changes the action's own runtime — the node-version
it installs for user code is unaffected.

* Disable setup-node v5+ automatic package-manager caching
Preserves v4 behavior: caching only when use_node_cache=true.

* Add workload identity federation support to base-action
Move the workload identity module into base-action so the standalone
action can fetch and refresh the GitHub OIDC identity token itself, and
expose the same federation inputs as the outer action. Switch the
base-action test workflows from the anthropic_api_key secret to the
federation repo variables and grant them id-token: write.
* Verify MCP test tool invocation instead of init connection status
MCP servers can connect asynchronously, so the init event may report a
server as pending. Check that the server is registered at init, then
assert the test tool was actually called and returned its response.
Also pass the MCP config through claude_args --mcp-config, replacing the
removed mcp_config input.
Switch claude.yml, claude-review.yml, and issue-triage.yml from the
anthropic_api_key secret to the workload identity federation inputs.
The federation rule, organization, and service account IDs are read
from repository variables; issue-triage.yml additionally gains the
id-token: write permission required to request the OIDC token.
* Add workload identity federation auth support
Adds anthropic_federation_rule_id, anthropic_organization_id,
anthropic_service_account_id, anthropic_workspace_id, and
anthropic_oidc_audience inputs. When the federation rule and organization
are set, the action fetches the workflow's GitHub Actions OIDC token,
writes it to a file in RUNNER_TEMP, keeps it refreshed during execution,
and points the Claude Code CLI at it via ANTHROPIC_IDENTITY_TOKEN_FILE so
the CLI can exchange it for a short-lived access token instead of using a
static API key.
* Add WIF example workflow and base-action federation docs
* Default workload identity OIDC audience to https://api.anthropic.com
Move the allowed_bots check in checkHumanActor and checkWritePermissions so
it only fires after the actor has been resolved as a non-User account
(GitHub App / bot, or unresolvable app actor). Actors that resolve to a
regular User account go through the standard human/write checks regardless
of allowed_bots.
The Copilot-style path (GITHUB_ACTOR not ending in [bot] and not resolvable
as a user) is unchanged: it still falls through to the existing 404 catch,
which already consults allowed_bots once the API has reported the actor is
not a user.
Update tests to match and add coverage for the User-account path.
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
