ais-prompts — Prompt Engineering
Files
| File | Mục đích |
|---|
templates/prompt-registry.py | PromptVersion + PromptRegistry — versioned templates, format() with kwargs |
templates/injection-defense.py | detect_injection() (6 regex patterns) + sanitize_user_input() |
templates/ab-test.py | ab_test_prompt() — random variant selection, log_result() for analysis |
templates/cost-aware.py | estimate_tokens() (rough 4 chars/token) + optimize_prompt() truncation |
Usage
from templates.prompt_registry import PromptRegistry
registry = PromptRegistry()
registry.register("qa", system, template)
messages = registry.format("qa", question="...")
Security: Always sanitize user input with sanitize_user_input() before passing to prompt templates. Check injection patterns on every user message.
Anti-Rationalization
| Excuse | Reality |
|---|
| "Prompt injection detection không cần" | User input bypass system prompt → jailbreak |
| "Versioning prompt thừa" | Không biết prompt nào đang dùng, rollback impossible |
| "A/B test xa xỉ" | Không biết prompt nào hiệu quả hơn |
Red Flags
- User input passed trực tiếp vào prompt
- Prompt không version
- Không injection defense
