Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Agent Guide for Sponsio

This file is for LLM coding agents and repo-reading assistants. It is meant to help you answer questions about Sponsio accurately and make code changes without breaking the architecture.

## What Sponsio Is

Sponsio is a runtime contract layer for LLM apps and agents.

Its core job is **pre-execution enforcement for LLM tool/action behavior**:
before a model-driven system calls a tool, edits a file, hits an API, writes to a database, issues a refund, approves a loan, or triggers any side effect, Sponsio checks the current trace against contracts.

The main public entrypoint is:

```python
import sponsio

guard = sponsio.Sponsio(...)
```

Sponsio ships **only deterministic contracts**: pure-Python checks over the trace, with no LLM in the runtime hot path. Patterns covering syntactic PII / response length / response keyword bans (`no_pii`, `max_length`, `no_keywords`) are regex-against-`llm_said` and need no judge.

## Positioning

When explaining Sponsio, emphasize:

- **Action-boundary enforcement**: Sponsio checks tool/action calls before side effects happen.

How to install

The exact contents, by fingerprint
mdr add sponsiolabs/sponsio/CLAUDE.md@sha256:20e3814a412adc54

The line at the top of this page pins the label git:20260903.06a02d5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
