Description
Chinese character conversion between Simplified/Traditional and regional variants. Use when Pi needs to convert Chinese text with precision and awareness of...
Usage Guidance
This skill appears coherent and purely focused on Chinese character conversion, but before installing you should: 1) Verify which opencc package you'll install (pip package name and maintainer) and pin a known-good version — malicious or typo-squatted PyPI packages are possible. 2) Confirm the opencc package you install provides the expected JSON mode files (s2t.json, s2tw.json, etc.) or supply them from a trusted OpenCC release. 3) If you require production or high-assurance use, audit the installed opencc package (check for native code, post-install hooks, and network behavior) and run the included tests (pytest test_convert.py). 4) No secrets or network endpoints are present in the skill itself, but keep general supply-chain caution for third-party dependencies.
Capability Analysis
Type: OpenClaw Skill
Name: opencc
Version: 1.0.0
The `scripts/convert.py` file is vulnerable to path traversal. The `--input` and `--output` arguments are directly used in `open()` calls without sanitization, allowing an attacker to read or write to arbitrary file paths (e.g., `/etc/passwd`, `~/.ssh/id_rsa`) on the system if the agent is instructed to use this skill with malicious input. This constitutes a significant file system access vulnerability, though it does not show clear evidence of intentional malicious behavior by the skill itself.
Capability Assessment
Purpose & Capability
Name/description, README, SKILL.md, pyproject.toml, scripts/convert.py, and tests all align: the skill wraps the OpenCC conversion library and exposes CLI and Python usage. There are no unrelated environment variables, binaries, or credentials requested.
Instruction Scope
Runtime instructions and the CLI script only read input text (positional argument, stdin, or an input file), perform conversion via opencc.OpenCC(...).convert(...), and write output to stdout or a file. They do not access external endpoints, secrets, or unrelated system files. Note: the skill expects OpenCC JSON mode files (e.g., s2t.json) to be available via the opencc package at runtime — the repo does not include those JSON files itself, so correct behavior depends on the installed opencc package providing them.
Install Mechanism
No registry install spec is provided in the skill metadata, but SKILL.md/README suggest installing via 'uv add opencc' or 'pip install opencc' and pyproject.toml declares dependency 'opencc>=1.2.0'. Installing a PyPI package is expected for this functionality. This is a normal install pattern, but the runtime depends on the authenticity and contents of the opencc package (which may include native components).
Credentials
The skill requests no environment variables, no credentials, and no config paths. All code operates on supplied text/files and uses the opencc library only — there is no disproportionate secret access or credential request.
Persistence & Privilege
The skill does not request always:true, does not modify other skills or global agent settings, and is user-invocable. It does not persist credentials or enable itself automatically in a privileged way.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install opencc - After installation, invoke the skill by name or use
/opencc - Provide required inputs per the skill's parameter spec and get structured output
