FiledProof

The tools are mostly well-differentiated by analytical operation (issuer resolution, filing inventory, passage search, evidence packaging, claim verification, chronology, lineage, cross-company matrix, change monitoring, financial fact reconciliation), and descriptions explicitly cross-reference alternatives. However, several tools occupy adjacent territory around filing comparison/history (build_disclosure_lineage, build_timeline, compare_filings, check_disclosure_changes, check_material_filing_changes), so an agent could still misselect without carefully reading the routing guidance.

All 13 tools use the same filedproof. namespace prefix and a consistent snake_case verb_noun or verb_object pattern (build_disclosure_lineage, check_disclosure_changes, compare_filings, list_filings, reconcile_financial_fact, etc.). There are no mixed conventions or vague names.

13 tools is well within the typical 3-15 range for a specialized SEC filing research server. Each tool appears to cover a distinct operation or paired workflow (preflight/reconcile, search/verify, lineage/matrix/timeline), so the count is not excessive for the domain.

The surface covers issuer resolution, filing listing, passage search, evidence packaging, claim verification, chronological and lineage views, cross-company comparison, disclosure change monitoring, and financial fact reconciliation. A minor gap is the absence of a direct full-filing retrieval tool (e.g., fetch a filing document by accession) or a broader issuer search beyond exact resolution, though search_evidence and list_filings partially compensate.
