CAUTION· install only

Publisher claims: "Check any agent skill or MCP server's security verdict before your agent installs it. Sandbox-based 0-100 verdicts (Verified, Caution, Blocked). Free, read-only, no account." Observed in sandbox: no network, touches nothing outside the project, writes no memory.

Coverage

Nothing executable in the bundle ran; the trace covers the install step only.
Tested
every file read, file written and host contacted by what ran
Not tested
use of the skill by an agent

What this means for the label: Caution here covers what ran. The server's tools were not exercised with a real credential, so nothing about their behavior is asserted; the credential summary below says what to do with that.

Before you give it your token

It will ask for
AWS_ACCESS_KEY_IDGITHUB_TOKENConfiguration, not credentials: CLINE_MCP_SETTINGS_PATH, COPILOT_HOME, DO_NOT_TRACK, KILLERSKILLS_API, USER_PROMPT, VET_GITHUB_APP_ID, VET_GITHUB_APP_KEY, VET_GITHUB_APP_KEY_FILE, VET_GITHUB_INSTALLATION_ID, VET_SKILLS_BIN, VET_SKILLS_FULL_DECISIONS, VET_SKILLS_HOME, VET_SKILLS_TELEMETRY, VET_SKILLS_TRUSTED_KEYS
Where it talks to
killerskills.ai (its own)
What the honeypot saw
no credential files read · no network
What we could not test
use of the skill by an agent

Connect it with a scoped credential, under the guard. It asks for AWS_ACCESS_KEY_ID, GITHUB_TOKEN and talks to killerskills.ai. Give the credential to the guard, not the server: the value never enters the server's environment and only travels to the host you bind. What the tools do with a real credential was not observed.

$vet-skills run --secrets AWS_ACCESS_KEY_ID=killerskills.ai,GITHUB_TOKEN=killerskills.ai -- <the server's command>

Never paste a credential into a chat, a ticket or a report, including ours. How the guard holds it.

Is [email protected] safe to install?

KillerSkills ran it in the KillerSkills honeypot sandbox (1 scenario; nothing executable in the bundle ran; the trace covers the install step only) on 2026-11-11 and scored it 68/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Access to sensitive file paths; References a credential file in the home directory; Access to sensitive file paths. Summary: no network, touches nothing outside the project, writes no memory.
