A4.1/5.0

Scored across 15 tools

Disambiguation4/5

The league-specific families are clearly separated, and calculate, equivalent, and movement tools have distinct purposes. The only mild overlap is between equivalent_*_salary and player_movement_* because both compare two teams, but the descriptions clarify that one solves for an equivalent gross salary while the other compares after-tax income at the same gross pay.

Naming Consistency3/5

All names use snake_case and the league-specific families are internally predictable across MLB, NBA, NFL, and NHL. However, the overall convention is mixed: calculate_mlb_tax places the league in the middle, equivalent_mlb_salary uses an adjective-first pattern, and player_movement_mlb places the league at the end.

Tool Count5/5

Fifteen tools is well-scoped for four leagues each needing calculation, equivalent-salary, and player-movement operations, plus three supporting utilities. Each league-specific tool earns its place by avoiding ambiguity in league selection and parameters.

Completeness4/5

The surface covers the core tax workflow: input discovery, player salary lookup, single-season calculation, equivalent-salary comparison, and team-movement comparison. Minor gaps exist around broader multi-team or multi-season comparison views and detailed tax-breakdown reporting, but the main agent workflows are supported.

Available Tools

15 tools
calculate_mlb_taxCalculate MLB taxAInspect

Calculate professional-athlete tax for one MLB season with the Jock Taxes engine. Ask the user for a missing team or salary. Do not invent team codes, seasons, salaries, or filing status. Call list_tax_calculator_inputs for allowed values. Send salary when the user has one season total taxed entirely as duty-day pay. Send base_salary plus optional signing_bonus and performance_bonus to match the site Salary + Bonuses form. Do not send salary together with base_salary or a bonus. exempt_signing_bonus_from_jock_tax defaults to true for a split, so the signing bonus is taxed only in the player's domicile. performance_bonus is included only when include_performance_bonus_in_jock_tax is true. art_xvi4_inducement_sb applies to an exempt signing bonus paid by a Canadian club to a U.S. resident. Present the result as a calculation, not as tax or legal advice. Required before this call: team, and salary or base_salary. Match a player with list_team_players only after league, team, and season_id are known. Repeat inputs and defaults from the result in the reply. Results are income tax only unless the user asks for take-home: then send include_payroll_taxes, agent_fee_pct, retirement_contribution (401(k), or RRSP on a Canadian club) or rca_contribution (Canadian clubs), and report result.net_pay. Comparisons then match on net_pay.net_economic, which counts an RCA after its estimated payout tax (rca_payout_tax_rate; default 25% Canadian withholding on the US-duty-day share and the US federal marginal rate on the rest, or 25% on all of it for a US person).

Inputs: team (required), salary, season_id, base_salary, +17 more. Returns: sport, inputs, result, defaults, +1 more
