SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Prompt Lab helps teams systematically test and improve agent instructions by running structured experiments, collecting evidence, and turning findings into reusable patterns to guide prompt design.

Core Features & Use Cases

  • Experiment-driven testing: Supports compliance, decay, adversarial, comparison, and reinforcement tests to reveal how prompts behave under different scenarios.
  • Evidence-based analysis: Provides a structured framework (Observation → Measurement → Diagnosis → Prescription → Verification) to quantify results and drive improvement.
  • Knowledge capture & reuse: Documents findings as case studies, patterns, and templates to accelerate future prompt work across teams.

Quick Start

Start by selecting a Skill unit (e.g., this one) and run a simple decay or compliance test using the provided templates. Design your task, embed the instruction, and record results with the standard YAML templates. Review the consolidated findings to iterate on prompt design.

FAQPage Schema
How do I test and validate AI agent prompts systematically?

To test AI agent prompts systematically, you can run structured experiments like compliance, decay, and adversarial tests to evaluate prompt robustness. This process uses an evidence-based analysis framework to quantify results and drive iterative improvement.

What is prompt decay testing and when do I need it?

Prompt decay testing is an experiment type that evaluates how prompt robustness degrades over extended or repeated interactions. You need decay testing when validating long-term agent performance and ensuring consistent instruction adherence across real tasks.

How do I run adversarial tests on agent prompts?

Running adversarial tests on agent prompts involves embedding malicious or edge-case instructions into structured tasks to evaluate robustness. You record results using standardized YAML templates to diagnose vulnerabilities and prescribe improvements through evidence-based analysis.

What's the best way to document prompt engineering experiments for reuse?

The best way to document prompt engineering experiments is recording results with standardized YAML templates. This captures findings as case studies and reusable patterns, enabling knowledge reuse and rapid iteration across teams for future prompt design.

Can I use evidence-based analysis to improve prompt compliance?

Yes, you can use evidence-based analysis to improve prompt compliance by following a structured framework of Observation, Measurement, Diagnosis, Prescription, and Verification. This quantifies compliance test results to drive targeted improvements in agent instructions.

Does prompt-lab work without external dependencies or components?

Yes, prompt-lab works without external dependencies or components. It operates as a standalone skill unit, providing internal templates and structured methodologies to execute prompt experiments and record evidence-based findings independently.
