/install hash-tool
功能描述
Compute cryptographic hash values of files and text. Use for verifying file integrity, checksums, and data validation.
使用说明 (SKILL.md)
Hash - Checksum Calculator
Calculate cryptographic hash values using algorithms like MD5, SHA-1, SHA-256, and SHA-512. Essential for file integrity verification.
Usage
hash-tool [options] \x3Calgorithm> \x3Cfile>
Algorithms
- md5, sha1, sha256, sha512
Examples
hash-tool sha256 file.txt
hash-tool md5 document.pdf
echo "data" | hash-tool sha256
安全使用建议
This skill appears to do exactly what it says: compute hashes locally. Before using, note that SKILL.md examples use a positional form (hash-tool <algorithm> <file>) while the shipped script expects flags (--algorithm/-a and --file/-f); also the script supports blake2b/blake2s and base64 output even though those are not listed in the README. There is no network activity or credential access in the code. If you plan to use it, review or run the script on harmless files first to confirm the CLI semantics you expect. Also remember MD5 and SHA-1 are cryptographically weak — prefer SHA-256/SHA-512 or BLAKE2 for integrity checks where collision resistance matters.
功能分析
Type: OpenClaw Skill
Name: hash-tool
Version: 1.0.0
The hash-tool skill is a standard utility for calculating and verifying cryptographic hashes (MD5, SHA-256, etc.) for files and strings. The implementation in scripts/hash.py uses the built-in hashlib library, follows safe file-handling practices (chunked reading), and contains no evidence of network activity, data exfiltration, or malicious prompt injection in SKILL.md.
能力评估
Purpose & Capability
The skill name/description (compute cryptographic hashes) aligns with the included Python implementation, which computes file and string hashes using standard hashlib algorithms. The code also supports blake2b/blake2s and base64 output in addition to the listed algorithms; this extends functionality but is consistent with the general purpose.
Instruction Scope
SKILL.md describes usage with positional arguments and lists only md5/sha1/sha256/sha512, but the script's CLI uses flags (--algorithm/-a and --file/-f) and supports additional algorithms (blake2b, blake2s) and a base64 encoding option. This is a documentation/CLI mismatch (not a security issue) — the instructions do not direct the agent to read unrelated files or transmit data externally.
Install Mechanism
No install spec is provided (instruction-only), and the included Python script is self-contained, uses only the standard library, and does not download or execute remote code. This is low risk from an installation perspective.
Credentials
The skill requires no environment variables, no credentials, and does not access configuration paths. The code reads only the file(s) specified by the user and uses standard library hashing functions — requested privileges are minimal and proportional.
Persistence & Privilege
The skill does not request always-on presence, does not modify other skills or system configuration, and its default invocation settings are standard. There is no indication it attempts to persist beyond normal skill behavior.
