ssti-error-based-detection skillA

ssti-error-based-detection is agent-read markdown (skill) from dreadnode/capabilities: Error-based blind SSTI detection using polyglot payloads and error message differentials to fingerprint template engines. Use when template injection is suspected but output appears blind, or when you need to identify the template engine before escalation..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add dreadnode/capabilities/ssti-error-based-detection@git:20260529.8f6ea0e
Exact content
mdr add dreadnode/capabilities/ssti-error-based-detection@sha256:cdd0c5e3b12fccb4

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
