testland/grpcurl-cli
Wraps grpcurl, the curl-equivalent CLI for gRPC. Covers descriptor sources (server reflection default, --import-path + --proto for proto files, --protoset for compiled descriptor sets), service discovery (`list`, `describe`), invoking unary RPCs (`-d '{...}'`, `-d @file.json`, `-d @` for stdin), streaming RPCs (newline-delimited JSON via stdin), TLS configuration (--cacert, --cert, --key, --insecure, --plaintext), header injection (-H 'Authorization: Bearer ...'), and exit codes. Use for ad-hoc gRPC debugging, smoke testing, scriptable PR-time gates, and CLI-based interaction with reflective gRPC services.

W013: Attempt to modify system services in skill instructions.
What this means
The skill prompts the agent to compromise the security or integrity of the user’s machine by modifying system-level services or configurations, such as obtaining elevated privileges, altering startup scripts, or changing system-wide settings.
Why it was flagged
The CI install step explicitly runs "sudo mv grpcurl /usr/local/bin/", which instructs modifying system-wide locations with elevated privileges and therefore asks the agent/user to change machine state requiring sudo.
Where we found it
sudo mv grpcurl /usr/local/bin/
command · 1 site
The CI workflow instructs running sudo to move a downloaded binary into a system-wide directory, requiring elevated privileges to modify machine state.

Low
Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
W012: Unverifiable external dependency detected (runtime URL that controls agent).
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
The CI step downloads and installs a remote binary at runtime (curl -L https://github.com/fullstorydev/grpcurl/releases/download/v1.9.3/grpcurl_1.9.3_linux_x86_64.tar.gz), which fetches and supplies executable code the skill relies on.
Where we found it
curl -L https://github.[REDACTED].9.3/grpcurl_1.9.3_linux_x86_64.tar.gz | tar xz
command · 1 site
The CI workflow downloads a remote binary tarball from GitHub at runtime and extracts it, fetching unverifiable executable code.

dependency · 1 site
The CI workflow invokes a GitHub Action as a hosted actor, which is a remote dependency executed at runtime.
