Evidence

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

Issue / PR body

Title: mcp-mail: Instructs the agent to modify its persistent memory or instruction files (KillerSkills verdict caution 70)

## 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 70/100**. Summary: calls astral.sh only, touches nothing outside the project, writes no memory.

- See the findings below.

- `src/mcp_agent_mail/cli.py:3123` · Instructs the agent to modify its persistent memory or instruction files — src/mcp_agent_mail/cli.py:3123 · Instructs the agent to modify its persistent memory or instruction files · informational: not an instruction file · informational: not an instruction file

## 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.
