Usage Guidance
This package appears to be a straightforward Marktplaats search CLI and JS client that only fetches data from marktplaats.nl and requires Node 18+. Before installing: (1) ensure you have Node 18+ available (SKILL.md and package.json require it); (2) review the full src/api.js (the provided bundle here was truncated) especially implementations of getListingDetails and fetchCategories to confirm they only fetch/parse marktplaats pages and do not call other domains or read local files; (3) run the CLI locally (npm install -g . or npx) and inspect network activity if you have concerns; and (4) prefer installing from a trusted source (npm registry or a verified repository) rather than an unknown package bundle. If you can provide the complete src/api.js (no truncation), I can raise my confidence to high after re-checking the remaining code paths.
Capability Analysis
Type: OpenClaw Skill Name: marktplaats Version: 0.3.0 The skill is classified as suspicious due to the `getListingDetails` function in `src/api.js`. This function accepts a `urlOrPath` parameter and will fetch any `http` or `https` URL if the input starts with either protocol. While intended for Marktplaats listing details, this broad network access could be exploited for Server-Side Request Forgery (SSRF) to probe internal networks or access unauthorized external resources if an attacker can control the input (e.g., via prompt injection against the agent or crafted CLI arguments). There is no explicit malicious intent like data exfiltration or remote code execution, but the capability to make arbitrary outbound requests is a significant risk.
Capability Assessment
Purpose & Capability
Name, description, package.json, CLI wrappers and API client all align: the code builds search URLs against marktplaats.nl, normalizes results, and exposes category/listing detail functions. The only small mismatch is that SKILL.md metadata and package.json state Node 18+ is required, while the registry metadata shown at the top listed no required binaries — functionally the skill does require a Node runtime to operate, which is reasonable for a JS CLI.
Instruction Scope
SKILL.md and CLI scripts instruct only to install the package (npm install -g or npx) and call the local CLI or programmatic exports. Runtime behavior described and visible in code is limited to HTTP fetches against marktplaats.nl and local CLI printing; there are no instructions to read arbitrary user files, environment variables, or to send data to unexpected third parties.
Install Mechanism
There is no registry install spec; installation is intended via npm (local path or global). The package has a normal package.json and no external download/extract steps. This is a common and low-risk install mechanism for a Node CLI.
Credentials
The package requires no secrets or external credentials and declares Node 18+ as the runtime. There are no environment variables or config paths requested, which is proportionate for a read-only search client.
Persistence & Privilege
The skill does not request persistent elevated privileges, always:false, and contains no code that modifies other skills or system-wide settings. It runs as a normal user CLI/module.
