Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (7)

`compile`read-only	Compile source code and return assembly output, stdout, and stderr
`generate_short_url`	Create a Compiler Explorer short URL for sharing code with compiler settings
`get_shortlink_info`read-only	Retrieve source and compiler config from a CE short URL. Compiler entries are returned in the `compile` tool's shape ({compiler, options, libraries:[{id, version}]}). Multi-pane shortlinks (executors, conformance views, CMake trees, per-compiler filters/tools) are flattened — only the basic compile inputs survive.
`list_compilers`read-only	List available compilers, optionally filtered by language
`list_languages`read-only	List supported languages. Each entry has `defaultCompiler` and `compilerCount`.
`list_libraries`read-only	List available libraries for a given programming language
`lookup_asm_instruction`read-only	Look up documentation for an assembly instruction
