# little-canary

Prompt injection detection library for LLM apps and agents.

Use this repo when you need to:
- screen inbound untrusted text before it reaches a main model
- combine structural pattern checks with sacrificial-canary behavior checks
- return a simple decision: block, flag, or pass

Primary entry points:
- Python API via `SecurityPipeline`
- local server via `little-canary serve`

Expected output:
- verdict object with safety, action, summary, and optional advisory text

Do not use this repo as:
- a guarantee that prompt injection is impossible
- a replacement for runtime containment controls
- a benchmark suite

Key success condition:
- the same configured pipeline and mocked backend produce the same verdict behavior across runs
