/install nansen-web-searcher
Description
Search the web for one or more queries in parallel. Use when you need current information, news, prices, or any web content to complement on-chain Nansen data.
Usage Guidance
This skill appears coherent overall but has one unexplained mismatch: SKILL.md says searches use the Serper API while the skill only requests a NANSEN_API_KEY. Before installing, confirm the official source of the 'nansen-cli' npm package (maintainer, repository link, and version). Check the package code or docs to see whether it actually calls Serper (and therefore needs a SERPER_API_KEY) or whether the SKILL.md contains a copy/paste error. Treat npm installs as moderate supply-chain risk—prefer installing only from an official Nansen source or pinned release, and restrict the NANSEN_API_KEY permissions if possible. If you cannot verify the package origin, consider not installing or running it in an isolated environment. If you want, I can try to locate the nansen-cli package metadata or repository to help verify its source and whether additional credentials are required.
Capability Analysis
Type: OpenClaw Skill
Name: nansen-web-searcher
Version: 0.1.0
The nansen-web-searcher skill is a standard utility designed to perform web searches via the Serper API using the 'nansen-cli' tool. The SKILL.md and _meta.json files contain legitimate documentation, scoped bash permissions, and standard environment variable requirements (NANSEN_API_KEY) without any evidence of malicious intent, data exfiltration, or prompt injection.
Capability Assessment
Purpose & Capability
Name/description match the declared requirements: the skill requires the 'nansen' CLI and a NANSEN_API_KEY, which is appropriate for a Nansen web-search helper. However, the SKILL.md explicitly says 'Search the web ... via the Serper API' while the declared primary credential is NANSEN_API_KEY (no SERPER_API_KEY or equivalent). This is an inconsistency in documentation vs. declared requirements and could be a simple doc error or indicate the CLI uses a different upstream service requiring an additional key.
Instruction Scope
Instructions are narrow: they show CLI invocations (nansen web search ...) and do not instruct reading arbitrary files or extra environment variables. They do reference excluded domains and an alternate 'nansen web fetch' command, but there are no instructions that access unrelated system state. The Serper mention in the text is the only notable oddity.
Install Mechanism
Install spec is a node package (nansen-cli) that creates a 'nansen' binary. Installing from npm is common but carries supply-chain risk (moderate). The spec does not point to an audited release host or a pinned version; verify the package source and maintainership before installing.
Credentials
Only NANSEN_API_KEY is required and it fits the described purpose. The documentation's reference to the Serper API raises the question of whether a second API key should be required; absence of a SERPER_API_KEY declaration is unexplained and should be clarified.
Persistence & Privilege
The skill is not always-enabled and does not request system-wide persistence. It appears to be user-invocable only and does not modify other skills or configurations.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install nansen-web-searcher - After installation, invoke the skill by name or use
/nansen-web-searcher - Provide required inputs per the skill's parameter spec and get structured output
