Scored across 21 tools
Most tools target a clearly distinct calculation (APL, heures supplémentaires, préavis, indemnités kilométriques), and inverse pairs like salaire_brut_en_net / salaire_net_en_brut are explicitly contrasted in their descriptions. There is real overlap among the statut/freelance cluster (auto_entrepreneur, portage_salarial, freelance_tjm_ca_net, comparatif_statuts all compute net income for overlapping regimes), which could cause misselection without reading descriptions closely.
All names are snake_case and readable, following a domain_noun convention (salaire_brut_en_net, indemnite_licenciement, seuils_micro_entreprise). Minor deviations exist: a few are verb-first or comparative (compare_offres, comparatif_statuts, simulation_apl), breaking the pattern slightly but not causing confusion.
21 tools is on the heavy side for a simulator suite, and the freelance/statut comparisons account for a cluster that could arguably be consolidated into one parameterized tool. Each tool does map to a distinct French payroll/tax calculation, so the count is defensible but borderline.
The surface covers the core French income lifecycle: brut/net conversion, chômage, APL, prime d'activité, congés payés, rupture, freelance statuses and TVA. Obvious gaps remain, notably a standalone impôt sur le revenu (barème) simulator and other aides sociales (RSA, allocations familiales), plus no salaried retirement contribution calculator.
