Each tool targets a distinct operation: compiling/running code, debugging with GDB, comparing outputs, reading a test case, and inspecting environment state. There is no meaningful overlap between these purposes, so an agent can select the right tool without confusion.

All names use snake_case and are action-oriented, mostly following a verb_noun pattern such as compare_outputs, read_test_case, and get_environment_info. Minor deviations like compile_and_run and debug_with_gdb introduce conjunction/preposition forms, but the overall convention remains predictable.

Five tools is well-scoped for a C++ olympiad-style assistant: compile/run, debug, compare outputs, read test cases, and check the toolchain environment. Each tool has a clear role, with no obvious filler or missing core capability at this scope.

The surface covers the core compile-run-debug-test workflow, including test case reading, output comparison, and environment inspection. Minor gaps remain, such as writing/editing source files, listing available test cases, or running a batch of test cases, but these can likely be handled outside this server.
