One thing to look at

  • 0 stars0 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

SKILL.md

1.2 KB, 231 tokens by cl100k_base, as published. Nobody here has run it

When to invoke

  • You are building an agent that reads untrusted content (web pages, emails, tickets) and you want a pre-flight safety lint.
  • You want to add an automated check to prompt templates before deployment.

Inputs needed

  • --prompt path to a text file containing a system/developer prompt, or combined prompt template.
  • Optional: --retrieved path to a text file with representative untrusted content.

Workflow

  1. Detect common prompt-injection markers ("ignore previous instructions", requests to reveal hidden prompts, tool/credential exfiltration).
  2. Check for missing boundaries (no explicit statement that retrieved content is untrusted; no tool-use constraints).
  3. Emit a JSON report with severity, evidence snippets, and recommended mitigations.

Output format

  • JSON report written to --output.

Guardrails

  • Heuristics only: do not claim the prompt is safe/unsafe with certainty.
  • Avoid printing full prompt contents to stdout.

Reference code

  • prompt_injection_risk_linter.py implements a vendor-neutral lint with stdlib regex.
