CyptoDataVault

Provides real-time cryptocurrency prices, on-chain Ethereum data, and DeFi metrics via unified API access to multiple exchanges and protocols.

Security Scan

The skill's manifest and runtime instructions claim a crypto data integration but the package contains multiple inconsistent/mispackaged pieces (mismatched dependencies, import paths, and test expectations) that don't line up with its stated purpose—worth caution before installing or giving it network/keys.

Purpose & Capability

The skill claims 13 tools and multi-exchange/on-chain access. That purpose would reasonably need network access and optionally blockchain API keys (Etherscan etc.). However the package is internally inconsistent: SKILL.json and SKILL.md list fastapi/uvicorn and ccxt, but requirements.txt omits fastapi/uvicorn; config/default.yaml lists DATAVAULT_API_KEY and many scan keys but the registry metadata declares no required envs. The code references app.* modules (app.data, app.onchain) which are not present in the provided file manifest, indicating the bundle is incomplete or mispackaged. These mismatches make it unclear what the skill actually does or needs.

Instruction Scope

SKILL.md itself provides narrowly scoped instructions for calling tools (get_price, get_eth_balance, etc.). But contained scripts (scripts/test.sh, scripts/setup.sh) instruct running tests and imports that reference a different package layout (they import from src and assert >=50 tools), and test assertions expect many more tools/fields than SKILL.md documents. The scripts also create a .env template and encourage adding API keys. The run instructions and tests therefore go beyond the documented skill surface and conflict with the packaged code.

Install Mechanism

There is no formal install spec (instruction-only), which is lower risk. The included setup script uses pip install -r requirements.txt and creates a virtualenv; requirements.txt contains common packages (requests, pyyaml, ccxt) and no external downloads or obscure URLs. However SKILL.json declares additional dependencies (fastapi, uvicorn) that are not reflected in requirements.txt, which is inconsistent and could lead to missing runtime packages if followed as-is.

Credentials

The skill declares no required environment variables in registry metadata, and SKILL.md says optional ETHERSCAN_API_KEY. Yet config/default.yaml and setup scripts include DATAVAULT_API_KEY and many blockchain scan keys (ETHERSCAN, BSCSCAN, POLYGONSCAN, ARBITRUMSCAN). Requesting those API keys would be proportionate for on-chain features, but the fact they are present in config but not declared in metadata is an inconsistency the user should notice before supplying secrets.

Persistence & Privilege

The skill does not request elevated persistence: always is false and it does not declare creating system-wide config or modifying other skills. It requests network access (per SKILL.json metadata), which is expected for a data provider.

What to consider before installing

This package appears mispackaged and inconsistent rather than overtly malicious, so proceed cautiously. Specific things to check before installing or running: - The repository is missing the referenced app/ modules (app.data, app.onchain). Ask the author for the complete package or the correct import layout (src vs skill vs app). - Dependency mismatch: SKILL.json lists fastapi/uvicorn but requirements.txt does not. Confirm which packages are actually needed and install in an isolated virtualenv or sandbox. - Tests/scripts refer to a different package name (src) and expect many more tools/fields than documented; these tests may fail or be lying about capabilities. Don't trust the test assertions as evidence of capability. - The bundle will ask you to create a .env with API keys (Etherscan, DATAVAULT_API_KEY). Only provide low-privilege/test keys first and never supply high-value credentials without verifying the code. - Run the code in an isolated environment (container or VM), inspect the missing app modules and network endpoints the code calls, and verify the GitHub link and publisher identity before granting network access or secrets. If you can't verify these items or get a corrected package/source, treat the skill as untrusted and avoid installing it into production or on machines holding sensitive credentials.
