A fix the maintainer can act on, with the evidence attached. It opens under your GitHub account in your browser; KillerSkills holds no token and never modifies the package. The fix is verified the only way we verify anything: the next crawl re-runs the new version in the honeypot. 68 · Caution
Evidence
The sandbox observed nothing beyond the static findings; the proposal cites those.

Title: prompt2mcp: Hidden zero-width characters detected (KillerSkills verdict caution 68)
## 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 68/100**. Summary: no network, touches nothing outside the project, writes no memory. - See the findings below. Full trace and findings: https://killerskills.ai/skills/pypi/prompt2mcp/0.5.1 ## Findings with a location - `mcp_factory/cli/__init__.py:1` · Hidden zero-width characters detected — mcp_factory/cli/__init__.py:1 · Hidden zero-width characters detected — may conceal content - `mcp_factory/generator/api_registry.py:611` · Prompting user to enter sensitive credentials — mcp_factory/generator/api_registry.py:611 · Prompting user to enter sensitive credentials — social engineering - `mcp_factory/generator/engine.py:1` · Hidden zero-width characters detected — mcp_factory/generator/engine.py:1 · Hidden zero-width characters detected — may conceal content - `mcp_factory/cli/main.py:1` · Hidden zero-width characters detected — mcp_factory/cli/main.py:1 · Hidden zero-width characters detected — may conceal content - `mcp_factory/llm/reviewer.py:1` · Hidden zero-width characters detected — mcp_factory/llm/reviewer.py:1 · Hidden zero-width characters detected — may conceal content - `tests/test_generator.py:1` · Hidden zero-width characters detected — tests/test_generator.py:1 · Hidden zero-width characters detected — may conceal content - `mcp_factory/llm/__init__.py:1` · Hidden zero-width characters detected — mcp_factory/llm/__init__.py:1 · Hidden zero-width characters detected — may conceal content - `README.md:309` · Fake instruction boundary tag — README.md:309 · Fake instruction boundary tag · informational: not an instruction file - `mcp_factory/generator/api_tools.py:1` · Hidden zero-width characters detected — mcp_factory/generator/api_tools.py:1 · Hidden zero-width characters detected — may conceal content - `mcp_factory/llm/interactive.py:1` · Hidden zero-width characters detected — mcp_factory/llm/interactive.py:1 · Hidden zero-width characters detected — may conceal content ## Proposed change The attached patch removes the 10 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.
