Repository Prompt Injection Security Scanner

A local command-line scanner identifies prompt injections and unvetted instructions inside codebases before coding agents run.

01 · The problem

A narrow problem worth validating

Autonomous coding tools execute dangerous terminal tasks without catching malicious instructions hidden in issues or markdown.

Who it is for

The first people to interview

DevSecOps engineers and developers using autonomous agent harnesses on open source or third-party repositories.

02 · Smallest useful version

What to build

A standalone Python or Node CLI tool scanning codebases for indirect prompt injections and dangerous triggers.

03 · Why it is worth exploring

Why this could be a practical first build

Trend reports emphasize rising security risks from repositories that attack connected coding agents.

04 · Evidence map

Evidence and sources

8 sources reviewed

Signal confidence · Early

Confidence is low because repository-specific injection scanners lack direct public validation records in the sources.

What this does not prove: Evidence relies on developer trend analyses highlighting agent-security vulnerabilities and general cybersecurity audit demand.
