Skill v1.0.0

version: "1.0.0" name: finngen-phewas-skill description: Fetch compact FinnGen PheWAS summaries for single variants by accepting rsID, GRCh37, or GRCh38 input and resolving to the required GRCh38 query. Use when a user wants concise FinnGen association results for one variant

Operating rules

• Use scripts/finngen_phewas.py for all FinnGen PheWAS lookups.
• Accept exactly one of rsid, grch37, grch38, or variant; resolve to the canonical GRCh38 chr:pos-ref-alt query before calling FinnGen.
• The script accepts max_results; start with max_results=10 and only increase it if the first slice is insufficient.
• Re-run the lookup in long conversations instead of relying on older tool output.
• Treat displayed ... in tool previews as UI truncation, not literal request content.
• If the user needs the full association payload, set save_raw=true and report raw_output_path instead of pasting large arrays into chat.

Execution behavior

• Return concise markdown summaries from the script JSON by default.
• Return the JSON verbatim only if the user explicitly asks for machine-readable output.
• Surface the canonical queried variant, total association count, truncation status, and any returned regions.
• Increase max_results gradually instead of asking for large association dumps in one call.

Input

• Read one JSON object from stdin, or a single JSON string containing the variant.
• Required input: exactly one of rsid, grch37, grch38, or variant
• Optional fields: max_results, save_raw, raw_output_path, timeout_sec
• Common patterns:
• {"grch38":"10:112998590-C-T","max_results":10}
• {"grch37":"10:114758349-C-T","max_results":10}
• {"rsid":"rs7903146","max_results":10}
• {"variant":"10:112998590:C:T","max_results":25,"save_raw":true}

Output

• Success returns ok, source, input, query_variant, max_results_applied, association_count, association_count_total, truncated, associations, variant, regions, variant_url, raw_output_path, and warnings.
• Use raw_output_path when save_raw=true.
• Failure returns ok=false with error.code and error.message.

Execution

echo '{"grch38":"10:112998590-C-T","max_results":10}' | python scripts/finngen_phewas.py
