Stegstr

Decode and embed Stegstr payloads in PNG images. Use when the user needs to extract hidden Nostr data from a Stegstr image, encode a payload into a cover PNG, or work with steganographic social networking (Nostr-in-images). Supports CLI (stegstr-cli decode, detect, embed, post) for scripts and AI agents.

This skill is internally consistent with its stated purpose, but follow these precautions before installing or running it: 1) Verify the GitHub repo (https://github.com/brunkstr/Stegstr) and the project source before building; 2) Don't set STEGSTR_REPO_URL to an untrusted location—only override the repo if you trust the target; 3) Be careful with private keys: do not paste secret keys into command lines or public shells unless you understand the risk; prefer using ephemeral/sandboxed environments when building and testing unknown binaries; 4) If you need to run this in a high-security environment, review the source code (or run the build in an isolated container) before executing the produced binary.

Type: OpenClaw Skill Name: stegstr Version: 1.0.1 The skill bundle is designed for steganography and Nostr integration, involving cloning a Rust project from GitHub and building a CLI tool. All actions, including filesystem permissions and the use of a private key as an explicit input for Nostr operations, are consistent with the stated purpose. There is no evidence of data exfiltration, malicious execution beyond standard build processes, persistence mechanisms, or prompt injection attempts against the agent to subvert its behavior. The installation script uses a legitimate default GitHub repository (https://github.com/brunkstr/Stegstr.git) and installs to user-local directories.
