Skill: Land Registry SPARQL (Low-Level Bash)

Use this skill when you want direct, controllable access to the Land Registry SPARQL endpoint and postcode-neighbour data.

Workflow

1. •If input includes a postcode, normalize it:
   • •tools/postcode.sh normalize "<postcode>"
2. •Validate it before building a query:
   • •tools/postcode.sh validate "<postcode>"
3. •Compose SPARQL directly (do not rely on wrappers).
4. •Execute query:
   • •tools/query_raw.sh --query "..."
   • •or tools/query_raw.sh --query-file ./examples/postcode_sales.rq
5. •Parse results.bindings in returned JSON.

Nearby Postcodes

To enrich a search area around a location:

tools/nearby_postcodes.sh --postcode "CT2 8ET" --radius-meters 2000 --limit 25

Use returned postcodes to drive follow-up SPARQL queries.

Error Handling Guidance

• •If endpoint call fails, retry once with a longer timeout.
• •If still failing, return a clear error with status and query context.
• •If postcode validation fails, ask for corrected input.

Design Intent

• •Keep tools primitive and composable.
• •Let the LLM decide filtering, query shapes, and post-processing.
