Grade A, minimal risk: 0 of 100 risk points, rated 2026-10-19. The grade rates what the skill and its scripts can reach on the machine of whoever installs it, across eight categories from shell execution to secrets access. How the score works.
This skill is a static markdown prompt for generating lean startup experiment ideas. It does not ship code or scripts, and its main effect is advisory: it helps the agent propose hypotheses, metrics, and validation methods for a new product idea.
| Category | Level | Why |
|---|---|---|
| Code & shell execution | 0 (none) | The skill contains no shell commands, scripts, or code execution paths; it is only instructional markdown. |
| Network access | 0 (none) | It includes outbound reading links in the text, but nothing that fetches data or sends information over the network. |
| Filesystem reach | 0 (none) | It does not read, write, or delete files outside the optional user-provided materials mentioned in the prompt. |
| Secrets & credentials | 0 (none) | It does not request tokens, passwords, API keys, or other credentials. |
| Privilege & persistence | 0 (none) | There is no sudo, install, service, shell, or OS configuration behavior. |
| Instruction hijack surface | 0 (none) | No hidden or conflicting instructions to ignore safeguards; the prompt only asks to design experiments and, if files are provided, read them first. |
| Irreversible actions | 0 (none) | It recommends experiments but does not itself send messages, deploy, purchase, post, or otherwise act autonomously. |
| Transparency | 0 (none) | The skill is fully readable markdown with no binaries, generated code, or opaque runtime content. |
