Description
Execute SQL, SPARQL, SPASQL, SPARQL-FED, and GraphQL queries against live data spaces and knowledge graphs via OpenLink's OpenAPI-compliant web services. Use...
Usage Guidance
This skill appears to be what it says: a set of templates and rules for routing queries to SPARQL/SQL/GraphQL endpoints (defaulting to linkeddata.uriburner.com). Before installing or enabling it: 1) Confirm you trust the default external endpoints (linkeddata.uriburner.com); queries (including any sensitive strings you include) will be sent there or to other remote endpoints. 2) Check your agent/runtime-level credentials — the skill references authenticated transports (MCP, chatPromptComplete, OPAL) but does not declare env vars; if your agent exposes global credentials those could be used when the skill attempts authenticated calls. 3) Avoid including secrets or sensitive PII in queries. 4) If you need stricter controls, restrict the skill's invocation to trusted users only or verify platform-level policies for network/credential access. Finally, note a minor inconsistency: the functions table lists UB.DBA.sparqlQuery with different signatures in separate rows (likely overloads but worth verifying with the provider).
Capability Analysis
Type: OpenClaw Skill
Name: sql-sparql-graphql-skill
Version: 1.0.0
The skill bundle is a legitimate tool for querying OpenLink's data services (Virtuoso, URIBurner) via SQL, SPARQL, and GraphQL. It provides structured templates in references/query-templates.md and clear protocol routing instructions in references/protocol-routing.md. The use of curl and REST functions is aligned with the stated purpose of interacting with live data endpoints like linkeddata.uriburner.com, and no indicators of malicious intent or unauthorized data access were found.
Capability Assessment
Purpose & Capability
Name/description match the actual behavior: the SKILL.md contains templates for SQL, SPARQL, SPASQL, SPARQL-FED, and GraphQL and explicit routing to URIBurner/OPAL endpoints. Required env vars or binaries are not declared and are not needed by an instruction-only query router.
Instruction Scope
Instructions are narrowly focused on building and executing queries and presenting/tabulating results. They explicitly direct the agent to call external endpoints (defaulting to linkeddata.uriburner.com) via curl, REST functions, MCP, authenticated chatPromptComplete, or OPAL. The skill does not instruct reading local files or unrelated system paths, but it does assume the environment may provide authentication for some transports; queries (and any user-provided content) will be transmitted to remote services.
Install Mechanism
Instruction-only skill with no install spec or code files; no artifacts written to disk by the skill itself. This is the lowest-risk install posture for this type of capability.
Credentials
The skill declares no required environment variables or credentials, which is consistent with an instruction-only router. However the runtime instructions reference authenticated transports (MCP endpoints, authenticated chatPromptComplete, OPAL) and note that MCP 'requires authentication' — meaning the skill expects credentials to be available in the agent environment or platform. This is not inherently incoherent but is important: if your agent runtime supplies AWS/other tokens globally, those could be used by the skill when it attempts authenticated calls.
Persistence & Privilege
always is false and the skill is user-invocable; it does not request permanent presence or attempt to modify other skills. Autonomous invocation is allowed (platform default) but not combined with any other high-privilege configuration here.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install sql-sparql-graphql-skill - After installation, invoke the skill by name or use
/sql-sparql-graphql-skill - Provide required inputs per the skill's parameter spec and get structured output
