/install pdf-compressor
功能描述
Compresses a given PDF file to reduce its size.
安全使用建议
This skill appears to do exactly what it says: compress a PDF using PyMuPDF. Before installing: (1) ensure the execution environment can install the listed Python dependencies or provides 'uv' as SKILL.md expects; (2) run it on non-sensitive PDFs first to confirm compression behavior and output quality; (3) be aware the tool writes the compressed file next to the input file (so verify file system permissions and that overwrites are acceptable); (4) review dependency versions in pyproject.toml if your environment has strict supply-chain policies. No credentials or network endpoints are requested by the skill.
功能分析
Type: OpenClaw Skill
Name: pdf-compressor
Version: 0.1.4
The skill bundle is a legitimate PDF compression utility that uses the PyMuPDF (fitz) library to reduce file sizes. The code implements standard optimization techniques such as font subsetting, image resampling, and metadata scrubbing, with input validation handled via Pydantic (src/models.py) and safe path generation using UUIDs (src/utils.py). No indicators of data exfiltration, malicious execution, or prompt injection were found.
能力评估
Purpose & Capability
The name/description (PDF compression) matches the code and dependencies (PyMuPDF, pydantic, loguru). The code only operates on a user-specified PDF path and produces a compressed output in the same directory.
Instruction Scope
SKILL.md and src/main.py limit actions to validating arguments, checking file existence, compressing the PDF, and printing a JSON result. There are no instructions to read other files, environment variables, or to send data to external endpoints.
Install Mechanism
There is no install spec in the registry metadata, but a pyproject.toml lists dependencies and SKILL.md's entrypoint uses the 'uv' tool ('uv run src/main.py'). This is operationally consistent but slightly inconsistent with the 'required binaries: none' metadata — the runtime assumes an execution environment that can install/supply dependencies (uv and Python packages). This is not a security issue but is an operational/incoherence note.
Credentials
The skill requests no environment variables, no credentials, and accesses only the PDF path provided by the user. There are no unrelated or excessive secret requests.
Persistence & Privilege
always is false and the skill does not request any elevated or persistent platform privileges. It does not modify other skills or global agent configuration.
