About this skill
The problem
Agent instructions often fail in production due to ambiguous framing, prompt injection vulnerabilities, or hallucination risks. Most developers rely on trial and error rather than a systematic audit of their system prompts.
What it does
- Evaluates instructions across eight dimensions including Injection Safety, Hallucination Risk, and Token Efficiency.
- Assigns a 0 to 10 score for each dimension to identify specific architectural weaknesses.
- Generates a diagnostic report with prioritized fixes categorized by severity.
- Produces a fully rewritten, production-ready version of the instructions with all improvements applied.
Why this beats prompting it yourself
Manual testing rarely covers edge cases like delimiters for untrusted data or specific token efficiency trade-offs. This skill applies a structured auditing framework that forces the agent to act as a repair engineer, not just a critic, ensuring every weakness has a concrete code-level fix.
Use cases
- Hardening RAG system prompts against prompt injection from external documents.
- Reducing token costs for high-volume agents without sacrificing reasoning quality.
- Converting vague natural language directives into strict, parsable output contracts.
- Optimizing complex multi-step workflows with appropriate chain-of-thought techniques.
