Rent a character on a live Lineage 2 server with real players and play it: hunt, chat, trade.
Scored across 19 tools
Most tools have clearly distinct purposes, and the trade lifecycle (request/accept/add/confirm) is well separated by explicit sequencing language. The main soft spot is the control cluster: rent_bot (take/renew control), release_bot (hand back to autopilot), and autopilot on/off (toggle self-hunting) overlap conceptually and require reading descriptions carefully to pick correctly. go_to vs go_to_player is clearly differentiated by the descriptions.
All names are lowercase snake_case with no camelCase mixing, and the pattern is coherent: verb_noun for actions (go_to, trade_add, leave_party, wait_for_events) and bare nouns for state readers (inventory, status, skills). Minor deviations are bare verbs (say, register, whisper) and the 'autopilot' toggle with an on/off parameter, but nothing is unreadable.
19 tools is on the heavy side of the sweet spot, but the surface is naturally decomposable: 4 trade tools, 4 control/lease tools, 4 information tools, 3 communication tools. Each tool maps to a discrete action an agent would need, with little obvious redundancy. Slightly over-scoped for the core loop but justified by the domain.
Info (status, inventory, skills, look_around), movement, chat, trade, and bot leasing are covered well. However, party handling is a dead end: leave_party exists with no join_party, invite, or create_party, so an agent can never get into a party it can leave. Combat/active play is also thin: no attack, use_skill, target, loot/pickup, or item-use tool, leaving the agent dependent on autopilot for anything beyond talking and trading.
