Adds .github/workflows/claude-review.yml, a workflow_call workflow that repos call from a 10-line claude-review.yml to get Claude reviews on every pull request, and .claude/skills/code-review/SKILL.md, the multi-agent review skill it runs. The workflow checks out this repo and copies the skill into the reviewed repo at run time, so each repo's own CLAUDE.md files drive the compliance checks. Findings post as inline comments on the diff; a summary comment is updated in place when nothing is found. Drafts are reviewed, every push is re-reviewed, and a new push queues behind a running review instead of cancelling it. Authenticates with the org CLAUDE_CODE_OAUTH_TOKEN, so reviews bill the Claude subscription. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

| 5. For each issue found in the previous step by agents 3 and 4, launch parallel subagents to validate the issue. These subagents should get the PR title and description along with a description of the issue. The agent's job is to review the issue to validate that the stated issue is truly an issue with high confidence. For example, if an issue such as "variable is not defined" was flagged, the subagent's job would be to validate that is actually true in the code. Another example would be CLAUDE.md issues. The agent should validate that the CLAUDE.md rule that was violated is scoped for this file and is actually violated. Use Opus subagents for bugs and logic issues, and sonnet agents for CLAUDE.md violations. | ||

Validate CLAUDE.md findings before filtering.
Step 5 validates only findings from agents 3 and 4. Step 6 then removes the unvalidated findings from agents 1 and 2. This prevents all CLAUDE.md compliance findings from being reported.
Validate findings from all four agents, or exclude validated compliance findings from the filter.

Do not update comments by heading alone.
A human or another automation can post a comment that starts with ## Code review. This command can then overwrite that unrelated comment.
Add a unique hidden marker to this workflow's summary comment. Filter by that marker and the expected comment author before PATCHing.

Deduplicate by issue identity, not only by line.
A later push can introduce a different issue on a line that has an old inline comment. Dropping every issue on matching lines suppresses that new finding.
Compare the current commit, path, line range, and a stable issue signature before removing a planned comment.

🌐 Web query:
For anthropics/claude-code-action@v1, does claude_args: --allowedTools "mcp__github_inline_comment__create_inline_comment"also permit Bash commands declared only in a SKILL.md frontmatterallowed-tools field?
💡 Result:
No, declaring a tool in the allowed-tools field of a SKILL.md frontmatter does not automatically grant that tool permission to run in the anthropics/claude-code-action@v1. When running in a GitHub Actions environment, the action operates within a restricted sandbox where tools must be explicitly allowlisted using the --allowedTools argument within the claude_args parameter [1][2]. Even if a skill's own SKILL.md frontmatter lists a specific tool (such as a Bash command or an MCP tool), the action requires that the tool also be named in the --allowedTools list passed to the action's claude_args [1][2]. Effectively, the allowed-tools specified in a skill's frontmatter define the tools that the skill is authorized to use if the overall execution environment permits them, but it does not bypass the top-level security restrictions enforced by the GitHub Action's claude_args configuration [1][2]. To successfully execute a skill that relies on specific Bash commands or MCP tools, you must include both the "Skill" capability (if invoking a custom skill) and the individual tools required by that skill in your claude_args configuration [2][3].

Allow the Bash commands required by the skill.
The skill declares Bash(gh ...) commands for PR retrieval, validation, comment deduplication, and summary updates. The workflow allowlist contains only mcp__github_inline_comment__create_inline_comment, so the Bash commands remain unavailable. Add the skill's Bash allowlist with the MCP tool.
