insidergraph

Each tool has a clearly distinct role: raw feed searches (get_insider_trades, get_material_events, get_planned_sales, get_stakes, list_recent_filings), identity resolution (find_company), orientation/aggregation (describe_coverage, company_profile), and derived cross-feed signals (cluster_buys, planned_vs_executed, trades_before_events). Descriptions explicitly delineate scope—e.g., company_profile is marked 'START HERE' and points to deeper tools—so an agent can reliably choose the right tool.

All names use snake_case, but patterns vary: most are verb_noun (get_*, list_*, find_*, describe_*), while several are noun phrases (company_profile, cluster_buys, planned_vs_executed, trades_before_events). This is a minor deviation from a single convention and remains readable, but it is not fully consistent.

11 tools is well within the ideal 3–15 range for an API focused on SEC insider data. Each tool earns its place: five raw feed searches, three cross-feed signals, two orientation/aggregation helpers, and one identity resolver, with no redundant or trivial tools.

The toolset covers the core insider domain: Forms 3/4/5, 8-K, Form 144, Schedules 13D/13G, identity resolution, and three derived signals. Minor gaps exist—no dedicated historical stake-change query (superseded 13D/13G history is archived but not directly searchable) and no cross-company insider profile tool—but agents can work around these with existing searches.
