GDC Portal
GDC Portal skill. Genomic Data Commons cancer data retrieval, mutation frequency analysis, clinical-genomic correlation, and multi-project data integration.
Use This Skill When
- Genomic Data Commons cancer data retrieval.
- Mutation frequency analysis.
- Clinical-genomic correlation.
- Multi-project data integration.
Required Inputs
- Research objective, decision target, or hypothesis.
- Available data, source constraints, and domain assumptions.
- Required outputs, success metrics, and deadline or reproducibility constraints.
Workflow
- Confirm scope, assumptions, and the exact artifact set to save.
- Apply the narrowest domain method that answers the request with defensible evidence.
- Save code, tables, figures, and intermediate outputs to files instead of chat-only output.
- State limitations, uncertainty, and any validation or sensitivity checks performed.
- Append skill selection, handoff I/O, and file writes to
logs/process-log.jsonl.
Deliverables
report.md: concise method, results, interpretation, and file inventory in the user's language.results/: structured outputs, metrics, model artifacts, or extracted findings.figures/: English-only charts, diagrams, or panels when visual output is needed.data/: processed or derived datasets when transformation occurs.
Available Tools (MCP)
External tools available via ToolUniverse MCP server.
Falls back to Python requests + public REST APIs when MCP is unavailable.

Quality Gates
If any gate fails: identify the specific failing check, fix the issue, and re-validate before proceeding.
Gotchas
- Database API versions change frequently. Pin the API version or record access date for reproducibility
- Gene/protein identifiers differ across databases. Map to a canonical namespace before cross-database queries
- Enrichment analysis p-values require multiple testing correction. Report adjusted p-values, not raw
Validation Loop
- Execute analysis and generate outputs
- Check:
- Method selection matches the research question and stated assumptions
- All outputs are saved to files (no chat-only results)
- Limitations and uncertainty are explicitly stated
logs/process-log.jsonl is updated with execution trace
- If any check fails:
- Identify the failing gate
- Fix the specific issue
- Re-run validation
- Proceed only after all gates pass
