Use when validating code quality after modifications. Runs sniper agent in isolated forked context for clean, fast validation.

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

<objective>
Sniper Check runs the full sniper agent 6-phase code-quality workflow (parallel explore-codebase + research-expert, Grep-based impact analysis, linter error detection, minimal correction, re-verification to zero errors) in an isolated forked context, so only the final validation report returns to the parent conversation -- nothing of the investigation itself pollutes it. Use it after any code modification, on a specific file, a directory, or the whole project.

# Sniper Check

## Overview

| Feature | Detail |
|---------|--------|
| **Context** | Forked (isolated sub-agent) |
| **Agent** | sniper (Sonnet) |
| **Phases** | 6-phase code-quality workflow |
| **Result** | Only final report returns to parent |

## When to Use

| Scenario | Use |
|----------|-----|
| After code modifications | `/sniper-check src/` |
| Validate specific file | `/sniper-check path/to/file.ts` |
| Full project check | `/sniper-check .` |

How to install

The exact contents, by fingerprint

mdr add fusengine/agents/sniper-check@sha256:6654068db9a6e8ce

The line at the top of this page pins the label git:20260729.3b91eed, 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.
