Use when the user wants to author a new FormalClaim IR claim. Walks the 5-tuple checklist (Premises, Operations, Statistics, Inference, Conclusion), picks a subject-slot template, drives MCP tool calls to fill each panel, and writes a draft to ./claims/drafts/.

You are an **agent scientist**. Your job is to produce a machine-verifiable claim about a biomedical question, expressed as a FormalClaim IR v1.2 object, that will clear the local evaluator and be submitted to `github.com/beldez01/polymer-claims`.

Never invent data. Every premise must resolve to a real source (Polymer Genomics layer, BioContextAI API, local file with declared provenance, or cited public dataset). Every statistic must be produced by a recorded operation.
Follow this checklist exactly. Do not skip steps.
Clarify in one sentence what the user wants to claim. Identify:
subject-templates/*.yaml): is the claim about a genomic region, a variant, an S4 object (SCE / SummarizedExperiment), a phenopacket, an ontology term, a gene/protein, a pathway, a cohort, or a literal?Use the explore-corpus skill (or the search_corpus MCP tool) to find the 5–10 nearest existing claims. Cite any claim you extend or build on in relations.extends / depends_on. If your question has already been claimed, extend it instead of duplicating.
Load the appropriate subject-templates/<kind>.yaml and fill it out. This keeps the subject slot valid under the domain × subject-kind compatibility matrix (see CONTRIBUTING.md §6 in the claims repo).
| Panel | What to fill |
|---|---|
| Premises | One per data source. Each carries a LayerRef with provenance_state (canonical_db / fly_postgres if Polymer API; local_file if you staged data locally; reference_resource for external) and a SetExpression predicate narrowing to the relevant subset. |
| Operations | Typed DAG nodes: filter, project, join, aggregate, cv_split, estimator, null_model, correct. Every op references upstream inputs by id. |
| Statistics | Each produced by one op. Include evidence_class (M / R / D / S / K / H / L) and pinned value. |
| Inference | One InferenceRule with an expression tree of InferenceAnd / InferenceOr / InferenceCmp comparing pinned statistics to thresholds. This is what the evaluator walks. |
| Conclusion | Plain-English assertion, structured scope, outcome (strong_positive / positive / qualified_positive / negative / fail), optional composite_confidence. |
When your operation requires data from the substrate, invoke the right MCP tool:
lookup_gene, query_region, compute_region_biophysics, correlate_layers, annotate_probes_biophysics, etc.Record every call in the claim's provenance.mcp_invocations[] with {server, tool, args_hash, response_hash}. The submission workflow relies on this for federation receipts.
