Prevent stale runs from publishing comments.
Lines 41-44 validate the head SHA only once. A later synchronize event does not cancel the active run. The old run can therefore publish comments for an obsolete diff through this POST rule.
Use pull-request-scoped concurrency with cancel-in-progress: true. Revalidate the head SHA and label immediately before publishing. Prefer host-side publication after the sandbox returns structured findings.

Load reviewer instructions from a trusted revision.
The workflow checks out github.event.pull_request.head.sha when the ai-review label triggers the job. It then uploads .github/skills/pr-review/SKILL.md from that checkout and instructs OpenCode to follow it exactly. A pull-request author can therefore replace the reviewer policy and influence up to three authenticated inline comments. Load the skill from the protected base revision or embed the trusted policy in the workflow.

OpenShell v0.0.110 sandbox exec cancellation client TERM remote process documentation
💡 Result:
In OpenShell v0.0.110 (and related versions), the sandbox exec functionality relies on a gRPC ExecSandbox unary request with server-streaming responses [1][2][3]. There is no native, documented mechanism for a client to send a TERM signal or interactively cancel a remote process mid-execution via the CLI's exec command [1]. Key limitations and technical context regarding execution and termination include: 1. Absence of Interactive Control: The ExecSandbox RPC is a unary call that accepts a single input payload and streams output back [1][2]. It lacks a bidirectional streaming mechanism, meaning there is no way for the client to forward signals (like SIGTERM or SIGINT), handle live keystrokes, or resize the terminal after the initial request is sent [1]. 2. Known Hang Issues: Numerous technical issues have been documented where sandbox exec hangs indefinitely after the remote process finishes [4][5][6]. This often occurs when the gRPC stream does not properly signal completion or when connection/relay state becomes orphaned [4][6]. 3. Termination Workarounds: Because the CLI lacks a built-in "cancel" or "terminate" command for exec sessions, users rely on external management: - External Timeouts: Applying a timeout via the calling environment (e.g., timeout command in Linux) is the standard method for forcing termination [4]. - Stdin Discipline: Some reported hangs are mitigated by ensuring stdin is closed explicitly (e.g., using stdin=subprocess.DEVNULL in Python or </dev/null in shell scripts), which allows the client to detect EOF and exit [5]. - SSH-based Alternative: For scenarios requiring interactive control or signal propagation, the documentation recommends using openshell sandbox ssh-config to generate a configuration entry, allowing users to connect via standard ssh instead of openshell sandbox exec [4][7]. For official management of sandbox lifecycles, refer to the documentation for commands like openshell sandbox delete or openshell forward [8][7]. However, these are designed for lifecycle management, not process-level control of individual exec calls [8].

Enforce the timeout inside the sandbox.
timeout -s TERM -k 30s 8m terminates only the local openshell client. sandbox exec has no documented CLI mechanism to forward TERM or cancel the remote process. The remote command can continue after the client timeout, so the workflow does not enforce an eight-minute execution bound. Add a server-side timeout or explicit remote cancellation.
