Claude Code, Skill
Agent Skills
Skills for working with Hookdeck Event Gateway (receive, queue, route, and deliver webhooks), Hookdeck Outpost (send webhooks and events to user-preferred destinations) and Hookdeck Inspect (free webhook test URLs: create one, wait for webhooks, and read what they sent).
Compatibility: Not stated.
Grade C
One Medium finding. Read the report before installing.
Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.
INSTALL_REMOTE_SCRIPT
Why this grade
- INSTALL_REMOTE_SCRIPT Medium
Fetches a script from the network and runs it (a pipe to a shell, or an install hook with a URL).
.github/workflows/test-agent-scenarios.yml, line 36
curl -fsSL https://claude.ai/install.sh | bash
Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.
Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.
What was checked
Plain notes from the hygiene checks.

Network
Concern
