GitHub Actions reusable workflow secrets inherit workflow_call declared secrets official documentation
💡 Result:
In GitHub Actions, secrets are not automatically passed to reusable workflows; they must be explicitly shared by the caller [1][2]. There are two primary ways to provide secrets to a called workflow: 1. Explicit Mapping: You can pass specific secrets by mapping them individually in the calling workflow under the jobs.<job_id>.secrets key. For this to work, the called (reusable) workflow must define these secrets in its on.workflow_call.secrets block [1][3]. 2. Inheritance using secrets: inherit: You can use the secrets: inherit keyword in the calling workflow to implicitly pass all secrets the calling workflow has access to (including organization, repository, and environment secrets) to the called workflow [1][4]. When using this method, the called workflow does not need to explicitly declare the secrets in its on.workflow_call.secrets block to reference them [1][5]. Key Considerations: - Security: Secrets are only passed to the directly called workflow. In a chain of workflows (A calls B, B calls C), secrets must be passed from A to B, and then from B to C [1]. - Environment Secrets: If a reusable workflow job specifies an environment, it can access environment-specific secrets associated with that environment directly [5]. However, if you rely on the inheritance mechanism, secrets: inherit allows the called workflow to access the secrets available to the calling workflow context [4]. - Limitations: Secrets cannot be referenced directly in if: conditionals [2]. If you need to use a secret in a conditional, set it as a job-level environment variable first [2].

Replace these with verified immutable pins, and replace secrets: inherit with an explicit VERTEX_AI_SERVICE_ACCOUNT_KEY mapping.

GitHub Actions reusable workflow workflow_call inputs checkout caller repository pull_request_target default branch
💡 Result:
When using GitHub Actions reusable workflows (workflow_call) in combination with the pull_request_target event and actions/checkout, there are critical security and behavioral considerations regarding which repository is checked out and how pull request code is handled [1][2]. 1. Repository Context: When a reusable workflow is called, it runs as if it were part of the caller workflow [3]. If the called workflow uses actions/checkout without specifying a repository, it checks out the repository that hosts the caller workflow, not the repository that hosts the called workflow [3]. 2. Pull Request Target and Checkout Security: The pull_request_target event runs workflows with access to the base repository's secrets and GITHUB_TOKEN, even when triggered by a pull request from a fork [1][2]. To prevent "pwn request" vulnerabilities—where attacker-controlled code from a fork is executed in this trusted context—actions/checkout (as of v7) refuses to check out fork pull request code by default when triggered by pull_request_target [4][2][5]. 3. Default Branch Behavior: If actions/checkout does not receive an explicit ref parameter, it defaults to the default branch of the repository being checked out [4][5]. In the context of pull_request_target, this means it checks out the base repository's default branch rather than the head of the pull request [1]. 4. Opting Out of Protections: If your workflow requires checking out fork pull request code (e.g., for security-audited CI tasks), you must explicitly set the allow-unsafe-pr-checkout: true input on the actions/checkout step [1][2][5]. This should only be done after thoroughly reviewing the risks, as it allows the execution of untrusted fork code with the base repository's elevated privileges [1][2]. 5. Workflow Inputs: Inputs defined in on.workflow_call.inputs can have default values [6]. If no value is passed from the caller workflow and no default is specified, the input defaults to false (boolean), 0 (number), or an empty string (string) [6]. Note that the inputs context within these default value definitions does not contain inputs from the workflow being called [7].

Do not require a PR-only skill file from the default branch.
The reusable workflow checks out the caller's default branch, then runs test -f "caller/$SKILL_PATH". The master branch does not contain .github/skills/pr-review/SKILL.md, so this job fails before the review runs. Remove skill-path until the file is merged into master.

Keep ProcessSignalPublisher usable after Reset().
RateLimitCache::ResetRateLimitCache() destroys limiter_ without replacing it. ProcessSignalHandler::Stop() calls this method. The next Publish() reaches RateLimitCache::Allow() and dereferences the null pointer. Clear cache_ or recreate limiter_ in RateLimitCache::ResetRateLimitCache().
