Usage Guidance
This skill appears coherent and low-risk: it runs a small Python script that makes HTTPS requests to exchangerate-api.com and prints exchange rates. Before installing, consider that the skill will make outbound network requests (so it requires network access) and depends on a third‑party API (rate limits and availability apply). If you require provenance, note the skill has no homepage/source URL in the metadata — if you need an auditable origin or long‑term maintenance guarantees, ask the publisher for a repository or verify the owner identity.
Capability Analysis
Type: OpenClaw Skill Name: currency-exchange Version: 1.0.0 The OpenClaw skill bundle is benign. The `SKILL.md` file clearly describes the currency exchange functionality and its reliance on exchangerate-api.com, with no evidence of prompt injection attempts against the AI agent. The `scripts/exchange-rate.py` script accurately implements this functionality, making network requests solely to the declared `https://api.exchangerate-api.com/v4/latest` endpoint. There are no signs of data exfiltration, unauthorized command execution, persistence mechanisms, or obfuscation. Input handling is basic but does not introduce shell injection vulnerabilities as arguments are processed internally by Python functions.
Capability Assessment
✓ Purpose & Capability
Name/description, SKILL.md instructions, and the included script all align: they fetch rates from exchangerate-api.com and perform conversions. No unrelated binaries, env vars, or config paths are requested.
✓ Instruction Scope
Runtime instructions are limited to running the included Python script with commands like convert/rate/list. The script only performs outbound HTTPS GET requests to the declared API and prints results; it does not read local secrets, files, or other system state.
✓ Install Mechanism
There is no install spec. The skill is instruction-only with a single Python script included; nothing is downloaded at install time and no archives or external installers are used.
✓ Credentials
The skill requires no environment variables or credentials. The included code does not access any undeclared env vars or secret material.
✓ Persistence & Privilege
The skill is not marked 'always', does not modify other skills or system configs, and does not request persistent privileges. It can make outbound network calls when invoked, which is expected for its purpose.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install currency-exchange
  3. After installation, invoke the skill by name or use /currency-exchange
  4. Provide required inputs per the skill's parameter spec and get structured output
