The sandbox observed nothing beyond the static findings; the proposal cites those.

Title: mcp-halflist: Hidden zero-width characters detected (KillerSkills verdict caution 56)
## What the honeypot observed KillerSkills ran **[email protected]** in an isolated sandbox (decoy credentials, recording proxy, syscall trace; engine 1.8.1) and scored it **CAUTION 56/100**. Summary: static analysis only — behavior not yet observed. - See the findings below. Full trace and findings: https://killerskills.ai/skills/pypi/mcp-halflist/1.0.0 ## Findings with a location - `tests/servers/poisoned_server.py:44` · Hidden zero-width characters detected — tests/servers/poisoned_server.py:44 · Hidden zero-width characters detected — may conceal content - `tests/servers/poisoned_server.py:16` · References a credential file in the home directory — tests/servers/poisoned_server.py:16 · References a credential file in the home directory - `tests/servers/poisoned_server.py:16` · Reads credential paths from the home directory — tests/servers/poisoned_server.py:16 · Reads credential paths from the home directory - `src/halflist/suites/security.py:73` · References a credential file in the home directory — src/halflist/suites/security.py:73 · References a credential file in the home directory ## Proposed change The attached patch removes the 3 lines above. If the behavior is intended, the fix is to declare it instead: list the host under `permissions.network` (or the MCP manifest) and say in the README why the package needs it; the next crawl will re-score it with the declaration taken into account. ## How this will be verified Nothing is "verified safe" by assertion. When a new version is published, KillerSkills re-runs it in the honeypot and the verdict page updates; you can trigger it early from the verdict page ("Re-scan after I publish a fix"). Reply here or at [email protected] if you believe the verdict is wrong; disputes are reviewed by a person and the outcome is published on the verdict page. _Proposed through killerskills.ai/threats by a user of the package, under their own GitHub account. The evidence is public; the package was never modified by KillerSkills._

We count proposals opened, not merged: a merge shows up as a new version that the crawl re-runs. Disputes: the maintainer can contest the verdict from its page; a person reviews it and the outcome is published.
