gostman@r1
CAUTION· install onlyPublisher claims: "API client for coding agents. Sends saved HTTP, GraphQL and gRPC requests, runs collections with their checks, and creates or edits requests over stdio or loopback HTTP, with secret values redacted and calls limited to an allowlist of hosts." 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
FAKE_TOKENPLACEHOLDER_TOKENConfiguration, not credentials: PROD- Where it talks to
- no vendor host named in the codeAlso postman.com, usebruno.com, insomnia.rest, thunderclient.com, hoppscotch.com, yaak.app, xmlsoap.org, httpbin.org, openxmlformats.org — not the publisher's domain; check what for before connecting.
- 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, and read the third-party hosts first. The code names postman.com, usebruno.com, insomnia.rest, thunderclient.com, hoppscotch.com, yaak.app, xmlsoap.org, httpbin.org, openxmlformats.org as well as its own vendor. The guard injects FAKE_TOKEN, PLACEHOLDER_TOKEN only into requests to the host you bind (and its subdomains) and refuses the rest.
Never paste a credential into a chat, a ticket or a report, including ours. How the guard holds it.
Is gostman@r1 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 2026-11-14 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: README tells the reader to bypass SmartScreen; README tells the reader to click past SmartScreen; README links to an external installer. Summary: no network, touches nothing outside the project, writes no memory.
