Description
Compute SHA family hash values for file integrity verification. Use for checksums, data validation, and security verification.
README (SKILL.md)
SHA - Secure Hash Algorithm Calculator
Calculate SHA-1, SHA-256, SHA-384, and SHA-512 hash values for files and text input. Used for verifying data integrity and file authenticity.
Usage
sha-tool [options] \x3Calgorithm> \x3Cfile>
Supported Algorithms
1orsha1: 160-bit hash256orsha256: 256-bit hash (default)512orsha512: 512-bit hash
Examples
sha-tool 256 document.pdf
sha-tool 512 file.bin
echo "data" | sha-tool 256
Usage Guidance
This skill looks safe for local checksum use. Before installing, confirm how the `sha-tool` command is actually provided and note that the included script only computes SHA-256, despite the documentation mentioning additional SHA algorithms.
Capability Analysis
Type: OpenClaw Skill
Name: sha-tool
Version: 1.0.0
The skill provides a straightforward utility for calculating SHA-256 hashes via a Python script (scripts/sha256.py). While the documentation (SKILL.md) claims support for multiple SHA variants (SHA-1, 512, etc.) that are not implemented in the provided code, the existing logic is safe, lacks any malicious indicators, and performs its stated function without suspicious side effects.
Capability Assessment
Purpose & Capability
The purpose is coherent, but the documentation claims SHA-1/SHA-256/SHA-384/SHA-512 support while the provided script only implements SHA-256.
Instruction Scope
The instructions are limited to computing hashes for files or standard input and do not contain prompt-injection, persistence, or unsafe autonomy instructions.
Install Mechanism
There is no install specification, and SKILL.md documents a `sha-tool` command while the manifest only includes `scripts/sha256.py`; this is a packaging/functionality caveat rather than a security issue.
Credentials
Reading a user-specified file or stdin is proportionate for a checksum tool, and the code prints only the SHA-256 digest.
Persistence & Privilege
No credentials, privileged paths, background services, persistence, or external communication are requested or implemented.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install sha-tool - After installation, invoke the skill by name or use
/sha-tool - Provide required inputs per the skill's parameter spec and get structured output
